Does it seem like no matter what you do, your computer is always out of battery power? It might be time to replace the battery. Every battery has a designed capacity-basically the amount of charge that it's designed to hold. Over time batteries lose their ability to hold a charge. This means that even though you're fully charging your battery, the actual amount of power that the battery can hold is going down.

Some of the telltale signs that your battery is going bad are shorter use times, and subsequently, shorter times to recharge. If you notice the amount of time you can spend unplugged is going down, then chances are your battery has lost much of its ability to hold a charge. Another sign that your battery might be on the wane is that it takes less time to recharge. A battery that's going bad might also cause your computer to turn off or hibernate unexpectedly, even if the battery meter displays ample capacity remaining (70 or 80 percent).

Fortunately, Windows can help you know when your battery is unable to hold a full charge. When your battery gets down to 40 percent of its original capacity (that is, it can only hold 40 percent or less of its designed capacity after it has been charged), you'll see a notification via the battery meter icon that your battery might be going bad. This notification is new in Windows 7-earlier versions of Windows can't notify you when your battery is going bad. If you don't want to receive this notification, you can turn it off by clearing the check box on the battery meter.

Many batteries will show signs of problems well before reaching 40 percent of their original capacity. Also, many computer manufacturers have programs that you can use to measure the performance of your battery. These programs might be more sensitive to battery problems and should be used first to check the condition of your computer's battery. For more information about solutions to this problem, see Solutions to common battery problems.

Note

Some computer manufacturers report the designed capacity of their batteries to be the level of the last full charge, so it's possible that your battery might be below the warning threshold without giving you any warning. If your computer continues to run out of battery too quickly, but your battery meter shows that it's fully charging, it might be time to consider replacing your battery. Check with your computer manufacturer for information about replacing your battery.

Using the battery meter to monitor power consumption

• The battery meter is a handy tool located in the notification area of the Windows taskbar that makes it easy for you to keep an eye your computer's power consumption. The battery meter icon indicates whether your laptop is plugged in or whether it's running on battery power . When you point to the battery meter, you can see the percentage of battery charge remaining as well as an estimate of how much time you have until you'll need to plug your computer in.
• When you click the battery meter icon, you can get more information-like which power plan you're using and, if you have more than one battery, how much charge is left in your second battery. You can also change power plans and access additional settings for managing more power options. For more information, see Battery meter: frequently asked questions.

Using power plans to save your battery

One of the easiest ways to save your battery without affecting the performance of your computer is to use one of the built-in power plans that come with Windows. Power plans are basically collections of hardware and software settings that control how your computer uses power. There are two power plans that come with Windows that are useful for laptops:

Balanced. This is the plan that most laptops use by default. It offers full performance and display brightness when you need it and saves power during periods of inactivity.
Power saver. This plan can help you get the most from a single battery charge. It saves power by reducing system performance and screen brightness.

In addition to the power plans that come with Windows, your computer manufacturer might offer additional plans. You can also create your own power plan, or customize the settings for one of the existing plans. For more information, see Change, create, or delete a power plan (scheme).

Getting the most out of your battery

In addition to using power plans to get the most mileage out of a battery charge, it's also important to take care of your battery to make sure you get the most life out of it.

• Make sure you're following the manufacturer's instructions for charging and maintaining your battery. Only use a charger and power cord supplied by the manufacturer.
• Don't let your battery get too hot (or too cold). A hot battery is a sign of trouble and usually means that your battery isn't working properly. You should stop using it right away. Also, make sure that your battery isn't exposed to extreme temperatures. Batteries are designed to work best at room temperatures. Avoid using (or even storing) batteries in extreme temperature conditions.
• Use your battery to keep it fresh. Don't keep your computer plugged in all the time. It's a good idea to discharge and then recharge your laptop battery about once a month. Also, you should let your battery run down before you recharge it.

Dunhuang, China want to build solar power base

Dunhuang, China want to build solar power base

Dunhuang, one located in the Silk Road, the historic and cultural city, with bright well-known desert civilization and art. Here, the monuments to show the glory days are past, but in the outside corner of the vast Gobi Desert is brewing in recent years, the construction of a number of years ancient cultures co-exist with high-tech industries.

Enter the second decade of the 21st century, Dunhuang desert sun is creating a large-scale advanced modern industries - solar photovoltaic industry. According to the next round of the western development plan, it will be China's new energy base map is an important component.

With foreign correspondents last week to this group are being built into the desert to visit the local city photovoltaic PV industry. Dunhuang city 13 kilometers away in the clean energy industrial park, a large-scale photovoltaic power generation projects into the reporter's attention, reflects the development of China's ambitions in this regard.

SDIC Dunhuang 10 megawatts (MWp) Photovoltaic power generation demonstration project concession covers an area of about 500 acres (33 hectares), is the first large-scale photovoltaic power generation demonstration project concession. According to the Dunhuang PV SDIC any Tao, general manager, the project officially started in September last year, this month will be put into operation all the PV modules, the entire construction process less than a year.

China occupies the leading position of photovoltaic cells

China's current production capacity of photovoltaic cells occupy the dominant position, which in 2009 produced a total of 32% of the global battery. Mainland and Taiwan accounted for a total of 45% of the total global supply. In the photovoltaic industry in recent years, rapid development in China against the backdrop of this country to vote in the Dunhuang photovoltaic project is one hundred percent "Made in China."

Baoding Yingli Group, Jun Shi Fujian Energy Co., Ltd., Hefei Sunlight Power Supply Co., the manufacturer of photovoltaic panels and inverters, constitute the country's investment in the Dunhuang project. Ren Tao said: "All equipment, including control center equipment, all made in China, virtually no imported equipment."

The total project investment 179 million yuan (RMB, about 36 million dollars), designed annual generating capacity of 15,299,800 kwh (kWh). After the operation, the solar panels made of photovoltaic modules into the Northwest power grid will be integrated into national service in Xinjiang, Ningxia, Qinghai and other provinces. Photovoltaic power generation is still part of the high cost of power generation business, without government subsidies, corporate investment is not cost-effective.

Ren Tao pointed out that the cost of investment, the current unit of kilowatt hydropower needs 10,000 to 11,000 yuan or so per kilowatt of wind power is 11000-12000 yuan. The most expensive investment per kilowatt of photovoltaic power generation needs to 17,000 yuan.

He said the project is the electricity price per kilowatt-hour 1.0928 yuan, of which about 80% of the state subsidies. PV module life expectancy of 25 years, according to estimates, the entire power plant cost recovery period is 8 to 10 years, next year there will be 50 million to each of 700,000 yuan profit.

Dunhuang, long sunshine hours, annual sunshine time of 3310 hours of sunshine percentage of 75%, China's solar energy resource-rich region - with the development of photovoltaic power generation industry, special advantages, coupled with flat open, large-scale construction ideal strategy for large-scale photovoltaic power station development area.

In addition to national investment projects, currently built in Dunhuang China Guangdong Nuclear Energy Development Corporation of the Commonwealth 10 MW photovoltaic power generation projects.

In early May, the State Council issued "on the further support of a number of economic and social development in Gansu opinions", which calls for: "speed up to focus on solar power Dunhuang demonstration base, and strive to 2020 million-kilowatt solar power above the base."

Ren Tao said the completion of the first phase of 10 MW photovoltaic project, the second phase will start in the second half of this year, an additional 10 MW, one square kilometer of solar power plants could eventually be 30 megawatts of photovoltaic panels laid .

Ren Tao said: "In accordance with local planning Dunhuang, Dunhuang City, in 2020 the total installed capacity to reach 10 trillion, can be said here to the unparalleled, certainly one of the world's largest photovoltaic industry base."

Behind the hype value of the geometric heart of lithium

Behind the hype value of the geometric heart of lithium

The long-depressed stock market finally ushered in a wave rally last week, the harvest of five, while Yang Xian, Shanghai rebound 6 percent, the Shenzhen market rebounded 17%. Major sections you Changba me play, highlights the market wave after wave of enthusiasm is risen. But to say that one of the most eye-catching plate, it is none other than non-new energy.

20, in the first half of 2010 the economic situation of the energy conference, the National Energy Board Planning Division, River ice disclosure of the "emerging energy industry planning" related news, this positive impact of the new energy sector rose, while the development of new energy Auto is planning one of them. Among them, the lithium battery industry, the new energy automotive industry is undoubtedly the most promising sector in the plate.

Shine on the concept of the lithium battery when it appeared in a particular listed company, which is announced on Wednesday announced its withdrawal from the lithium battery industry Magicstor [7.52 -1.83%] (600 920). Why the market both in the policy of positive circumstances will opt out Huiton lithium batteries? This exit will move on Magicstor what impact? Future developments in the field of lithium batteries how? On this series of questions, the reporter carried out some interviews and surveys.

Lithium long-term business losses

July 21, Magicstor company held its third board meeting of the eighth, and at the meeting examined and adopted the company's lithium batteries out of the business motion, Magicstor transfer to be held outside all Guizhou Aerospace Power Technology Co., Ltd. (hereinafter referred to aerospace power) shares. Notice that in Magicstor, Magicstor make this decision mainly because of poor management aerospace supply company, in 2009, operating income was 87.66 million yuan, loss of 17.46 million yuan. A lot of losses down the company's profitability. And this situation has not been significantly improved this year, aerospace power in the first quarter operating income of 20.66 million yuan, loss of 1.46 million yuan. Long-term loss of leisure finally Magicstor lost patience on the lithium battery business, the company determined to sell their entire stake aerospace power. Currently Magicstor holds 37.81% stake in the company, and provide 12.9 million yuan loan guarantees.

Reporters on the matter of Magicstor company conducted a telephone interview, the company insisted that all the news side to notice. Magicstor recently announced that, due to space power losses, the company to improve profitability, the company decided to transfer all the shares. This transfer of shares of aerospace power in line with company's development strategy will help companies improve the efficiency of resource allocation, focus on core business unit strategy, enhance core competitiveness. After the transfer, the company is no longer a shareholder of space power, space power will no longer be included in the consolidated financial statements of the scope of the company, will help improve the company's overall operating efficiency, the lifting of aerospace power will provide loan guarantees of 12.9 million yuan, will help reduce the company's operational risks. This is consistent with company strategy, is consistent with the interests of all shareholders.

Transfer of ownership is indeed wise

How should we treat Magicstor that this practice? State Securities [14.49 1.05%] Mao Rui new energy analyst believes that this is a very normal behavior.

As the current long-term loss of aerospace power, in the performance of Magicstor had not a small negative impact, although the policy is expected to support visible, but for space power is not necessarily able to enjoy the preferential policy. Aerospace power is the main business of lithium batteries for mobile phones in domestic production, as has been weak competitiveness of domestic mobile phone market share has been limited, annual loss of aerospace power, coupled with a very low threshold for cell phone lithium battery production, small start-up capital, technology low level of market competition is very fierce. The recent capital market is very hot lithium battery concept is aimed at the car battery and other battery. This type of battery R & D costs are very high early on funds, technical requirements are very high; with aging facilities and space power, capital and technology are difficult to compliance, the transition difficulties, the transfer of equity refused to concede defeat.

Generally believed that the equity transfer are indeed able to eliminate the operating loss of aerospace power's negative impact on company performance, but due to the current concept of lithium batteries in the market is very hot, which to some extent reduce the operation of the subject company's stock price of space, this approach is There are two-sided nature. And not because the share price Magicstor this hot and blew out of lithium batteries, 21, after the announcement, although the company's share price all the way to shock, but Friday's closing price is still 7.52 yuan, compared with 21 of the opening is only 7.72 yuan at least two cents.

Mao Rui pointed out that this phenomenon is very normal. While the Shanghai stock market last week, out of 5 with Yang, but mainly for the disk in the oversold rebound plate, is a valuation of oversold stocks. The concept of short-term speculation is not much, but the concept as a long-term lithium hot topic as the country's new energy policy implementation and continue to be market speculation. In fact, even the concept of lithium-related stocks, the recent trend is not satisfactory, just follow the broader market rebounded only synchronous, not too many bright spots. Markets for lithium battery industry "is not nice to make money" should be more clear understanding.

Lithium industry still needs development

Li-ion battery business for the annual mobile phone market losses, and that for the lithium battery in the battery business then? It also looks like a mirage just beautiful? Correspondents have made the following investigation.

Mao Rui pointed out that the lithium battery industry started relatively late, Despite the increased national policy support, but the new energy vehicle market has been slow development process, so far there is no large-scale public programs; combined with policy implications, have power over many Li-ion battery project, which to some extent, exacerbated the lithium battery industry competition in the market, resulting in a structural overcapacity, oversupply, leading to low lithium corporate marketing in general.

The final analysis, our lack of core technology lithium batteries, lithium battery industry in China is leading to poor operational level, the root cause of competition is too low. Lithium battery industry chain mainly consists of three parts: the upper reaches of lithium ore resources, lithium battery materials (including the cathode material, anode material, separator, electrolyte), and battery manufacturing and packaging. Technically, lithium battery materials, the highest threshold of thin film technology, now basically dependent on imports. Currently, only domestic Fosugufen [12.27 -0.65%] (000,973), a subsidiary of Jinhui Tech, Dongguan star-source technology, Xinxiang, Henan Douglas.Ryan, and other parties in the Division to provide a small lithium battery manufacturers have to use the diaphragm. The lithium battery materials, lithium carbonate is the key raw materials upstream, the current oligopoly structure of foreign companies.

Wuhan University: "low-carbon economy" of getting better

Wuhan University: "low-carbon economy" of getting better

A diameter of 20 cm "glass" at the sun's energy is gathered under a few seconds you can light a cigarette. This is a College of Chemistry and Molecular Sciences, Professor Liu Lijian demo scene.

Professor Liu Lijian said that this is actually a polymer condenser plate, in theory, sunlight intensity can be increased in recent times, the gathering of solar energy to generate temperatures above 600 ℃. His research group is using this condenser plates in the solar energy into chemical energy of the "low carbon" technology research.

"Low-carbon economy" is a hot topic in the Copenhagen Climate Conference, Prior to this, the first time the Chinese government publicly committed to quantified emissions reduction targets the world, decided to unit of GDP by 2020, greenhouse gas emissions below 2005 levels by 40% - 45%.

"Low-carbon economy" is that fossil fuels such as coal, oil, etc. to use as much as possible the use of biomass energy, wind energy, solar energy. "Low-carbon economy" rely on technology to ensure the realization. Reporters learned that, in Wuhan University, active in a group engaged in "low carbon" technology experts and scholars, they use biomass, wind, solar and other aspects of the research has been getting better, in the promotion of high-carbon to the "low carbon" , "zero carbon" research firm on the road forward.

Since 2003, Liu Jian group trying to gather the energy of sunlight to carbon dioxide and biomass such as straw, the reaction of carbon monoxide, a move not only the direct use of solar energy to biomass into carbon monoxide gas, but also by the carbon dioxide into carbon monoxide The process of solar energy into chemical energy, in order to achieve carbon dioxide recycling, save energy, increase energy, emission reduction and environmental protection in multi-effects. The simulation process has been completed a small trial is underway to expand testing.

Liu Jian, China's only straw produced annually about 11 million tons, all of them using only the equivalent of less than 4 million tons of carbon, can not meet the huge demand for social and economic development. To this end, his group still try to gather direct sunlight to make carbon dioxide into carbon monoxide, not only to energy conservation, is also expected from the "low carbon" to "zero carbon."

National New Century Talents Project selected candidates, Wuhan University, School of Physics, Professor Zhao Xingzhong the group is committed to solar cell research, some of the technology has been close to the world advanced level.

New solar energy as a renewable energy, is considered the most important new 21st century energy sources. The semiconductor material silicon solar cells, represented the first flourish. But its production process complexity and higher cost. In recent years, scientists from various countries have been working on developing some low-cost, highly efficient new solar cells. Low-cost dye-sensitized solar cells in recent years scientists have studied the hot spots.

Professor Zhao Xingzhong the auspices of "dye-sensitized solar cells," study abroad unique. Beginning in 2006, the group hosted 863 projects "solid polymer electrolyte modified nanocrystalline dye-sensitized solar cells", by ultrasonic irradiation, nano-particles doping techniques, aimed at modified solid-state electrolyte. Dyes excited by the sunlight, the photo-electron injection TiO2 porous film, transferred to the external circuit through the TiO2 can directly convert solar energy into electricity. Dye-sensitized solar cell production process does not produce carbon dioxide, does not produce environmental pollution. Unlike traditional semiconductor silicon solar cells, dye-sensitized solar cell silicon cell costs only 1 / 5.

Wind power generation is to promote the use of wind generators. Wind energy resource is clean, renewable energy, inexhaustible, is the permanent presence of local resources. However, the establishment of wind farms need to address the stability is not enough, and wind power reserves and transportation and other technical issues.

The school of Electrical Engineering focused wind and solar power, is leading in the "large-scale long-distance transmission of wind power," to explore the subject, the study targeted wind power planning, wind power access, and other technical aspects of wind power reserve. At present, Henan, Gansu and other places connected to the grid for wind power research for China's wind power access and long-distance transport to tackle technical problems.

Smart Grid is a research hotspot in recent years, the experts. U.S. President Barack Obama's energy plan after taking office, including the development of smart grid industry, to maximize the value of the U.S. National Grid and efficiency, creating the world's highest energy efficiency. In recent years, Electrical Engineering, a group of experts to join the smart grid research, network security, lightning protection and grounding, power quality, grid stability and other aspects of leading the country.

Chinese Academy of Engineering suggested that the state funding two billion boost electric car

Chinese Academy of Engineering suggested that the state funding two billion boost electric car

Recently at the 16th annual meeting of Chinese Academic of electric vehicles, the Chinese Academy of Engineering, said Yang Yusheng, a number of academicians from the Chinese Academy of Engineering study and discuss Yu-Sheng Yang drafting ideas on development of electric vehicles in China report has been submitted to the State Council. The report recommends, to promote the development of pure electric vehicles, we must accelerate the battery, especially lithium-ion battery R & D and development, the state should be allocated 2 billion yuan to establish battery research and development of major projects, raise the overall battery production technology.

YANG Yu-sheng told reporters that the development of pure electric vehicles, battery power is the key. "The United States has voted 15 billion, we should raise the level of battery production technology, while focusing to carry out original research, research and development to enhance the battery capacity of 10 to 15 years later to provide pure battery electric vehicles with proprietary intellectual property rights The core technology, research new battery. "

New energy vehicles around the "jump red"

In 2009, the strategy put forward new energy vehicles on China's new energy vehicles, "first year", were launched the "10 City, 1000" demonstration project, financial subsidies for new energy vehicles management approach and "automobile industry restructuring and revitalization plan." , which clearly stated the next three years, new energy vehicles create 500 000 new energy vehicles production. Issued in June of this year "regarding the development of the private purchase of new energy vehicles to subsidize pilot," which defined the central government on the private purchase of pilot cities, registration and use of plug-in hybrid electric passenger cars and passenger cars, give up to 6 million one-time subsidy.

With state support policies have been introduced and implemented, China's new energy automotive industry to fame. To the major Automotive Group as the basis, over a time of new energy vehicles have sprung up.

Published in the current local planning objectives, if the node 2012, Jilin planning objectives of new energy vehicles is five million, Shanghai is 10 million, planning to achieve 500 000 Tangshan pure electric vehicles; while Zhuzhou that "the construction of China's largest new energy automotive industry base ", Guangzhou will strive to create" new energy vehicles world-class R & D center and manufacturing base ", and Xiangfan, has recently proposed to the Xiangfan-year period in 2010-2015 to fight the one million level vehicle and engines, transmissions, axles and other important automotive parts assembly and manufacturing base.

According to the deputy mayor of Xiangfan City, Bin-Bin Wang, in recent years, Xiangfan implementation of the new energy vehicle development strategy, has been formed from the battery, drive motor, automatic transmission drive system, controller, bus chassis to the vehicle a more complete new energy vehicles chain, and in April this year with the Dongfeng Motor Corporation signed a "Xiangfan Automobile Industry Development Strategy to promote cooperation framework agreement." "Xiangfan Municipal Government attach great importance to the development of new energy automotive industry, the whole idea will be market-oriented, wind-based, the core component-based, policy support, while increasing the intensity of innovation, open attitude, cooperation, so that we Xiangfan new energy automotive industry to make economies of scale to make economic effects, social effects to make. "

Pure electric vehicles SANDOVAL

In Yu-Sheng Yang appears that China should give priority to the development of new energy vehicles, development of pure electric vehicles, namely the implementation of "step away" strategy. "Comparison of Japan, the United States and other developed countries can see the strategy, developed the technology route is changed to pure electric vehicles, such as METI Japan's innovative energy technology plan has been identified by the steering hybrid plug-in hybrid, and then the development of pure electric vehicles, while the United States "next generation" battery and electric car program, pure electric vehicles is the most models. "

The four ministries from the Ministry of Finance released for the private purchase of new energy vehicles subsidies can be seen, pure electric vehicles has become China's priorities for the development of new energy technology road vehicles, and major companies have stepped up the layout.

According to the reporter, Domestically, BYD dual-mode electric vehicle as offered to the transition, the electric car as the ultimate goal of the development plan, and the end of 2009 Dongfeng Motor's electric buses took the lead in the commercialization of the pilot into the industry and market-oriented phase, National Grid and Southern Power Grid have to step up the layout of electric charging stations gas to speed up the pace to snatch a piece of cake, supporting facilities, Hubei chasing New Energy Technologies developed the smart electric car PV charging pile, charging systems will also enter the industry so stage.

This Academy of Engineering report submitted to the State Department suggested that "five" period, China should first develop miniature, low-speed, short-range electric passenger cars as a transition, and gradually improved; second public buses and medium-sized program to increase high-end passenger cars as the main transition of pure electric drive vehicles, of course, the transition does not rule out other vehicles; third lay a solid foundation for a new generation of electric cars to leapfrog development direction to prepare. YANG Yu-Sheng said this, "if" five-second "We can do these three work, we will be the development of electric vehicles, a big step forward."

Key: battery

But the electric car industry can not be done overnight. Electric cars Engineering Branch of China Director Chen Quanshi stressed that this is a gradual process, through demonstration operations, expanding the scale of the application through the promotion of large-scale battery technology to further enhance, reduce battery costs, and improve the relevant technical standards.

Battery, motor and electric control system is a new energy vehicles three major components, including battery power is the key. The reporter has learned, the main bottleneck of electric vehicle technology is the battery technology, the current car battery's energy density is still relatively low, the stability of the battery life also needs further improvement.

"Right now the battery pack's cycle life is lower than 1000, while the pure electric vehicle battery cycle life if less than 1500, its economy will be greatly reduced." This Yu-Sheng Yang stressed that the acceleration power batteries, especially lithium-ion cell research and development is imminent.

"The future can be bigger and stronger a few power battery factory, and 5-10 years in which few can produce 50 million new battery factory, every plant was put into more than a billion; must also support the localization of cell production equipment We are now better production equipment are imported, spent a lot of foreign exchange, battery production equipment is now doing mechanical and electrical industry, new opportunities in China, but also for the future lay the foundation for a powerful battery supply. "

"The new energy and electric vehicle technology development through active investment, has won a huge market, and lithium-ion rechargeable battery market is in great transition." Battery test under 863 Prince, director of the winter is expected in the electric car market demand, driven by lithium-ion battery market in the next five years will exceed $ 20 billion, and the fierce competition and technological development has already begun, a series of new entrants making the market more lively.

Monitor UPS power capacity installed in the calculation of

Monitor UPS power capacity installed in the calculation of

How to determine what type of UPS you need power? Typically, personal office and home users to consider back-up models, such as the Hills-line UPS power low-cost, thin, light and is an ideal PC partner. Has a very high price; system for small and medium sized network users, servers, or precision instruments, the multi-line or line interactive UPS power supply, can better resist the power line from a variety of violations, its functional and Most intelligent monitoring and network connectivity, remote control and intelligent management. Important for large-scale equipment and systems, high-power Hills-line UPS power protection essential to provide a stable power supply. Specifically how to determine the required power (VA) size? Need to list all the equipment need to be protected, do not forget to display terminals, external hard drives. Voltage and current of each device on the backplane data can be found by multiplying the two can get VA. Some devices require electrical energy in watts that, you can see the tile was roughly 1.4 times the number of VA. For the whole device is its rated power as the base number. The aggregate value of all the VA facilities, will be aggregated value plus 30 percent expansion of capacity to prepare for the system upgrade with.

How to configure back-up delay time? Because different systems and equipment, select and configure the UPS power supply models are also different. UPS power supply standards of the machine itself comes with UPS batteries in general will continue to supply power after a few minutes to a few minutes; and long-acting UPS power supply with external battery pack, users can continue to supply extended power outage need to reserve time can be designed to ten minutes when the number of hours or longer. General long-acting UPS Power UPS battery backup time is mainly affected by the cost of installation space and battery recharge time and other factors. Generally the less electricity, power outages are more frequent in areas with a UPS power and generator power mode. When a power failure, UPS battery power first by a period of time, such as the outage time is longer, you can start the backup generator to supply power to the UPS, when electricity is restored and then switch to the mains supply. Battery life is mainly affected by the load size, battery capacity, temperature, battery discharge cutoff voltage and other factors. According to delay the ability to determine the size of the battery capacity required, with the security value to indicate when the AH to a given current amperage discharge time when the number of hours to calculate. UPS configuration to look at the general formula: UPS Power (VA) x delay (hours) / UPS battery power required to start the DC = Ann hours (AH) to Hills C3KS delay 4 hours, for example we calculate Next:: (Note: Hills C3KS to start DC: 96V) 3000 VA x 4 hours / 96V = 125AH 125AH battery results are needed to meet the four-hour power supply, but generally do not have regular UPS battery's capacity 125AH a group of eight (because C3KS start DC is 96V-(UPS standard at the factory DC), normally most of 12V DC battery, 96V (UPS startup DC) / 12V (Battery voltage) = 8, so in order to 8 batteries for a group) UPS batteries.

We can choose a 100AH battery to configure it; the delay time: 100AH (UPS battery capacity) x 96V (UPS startup DC) / 3000V (UPS Power) = 3.2 hours can also choose to group 2 (16 ) 65AH batteries of UPS in parallel configuration! the delay time: 65AH x 2 x 96V / 3000VA = 4.16 hours U.S. Hills UPS power supply voltage standard at the factory start DC: MT1000SC1KS C2KS-C3KS C6KS-3C20KS 3C3-10KS - 3C340KS 24VA 36V 96V 240V 384V U.S. Hills UPS power supply voltage output power factor are 0.7; such as Hills C1KS maximum support load power: 1000V x 0.7 = 700W, so the Hills C1K maximum support loading of 700W, and so on !! (Note: In order to make better use of the general UPS power supply, UPS power supply is best not to recommend no load / full load or overload use, UPS power supply load power is the best of its standard load of 70% -80%, such as C1K with the best load for the 500-600 (w) of the load! this UPS power supply can better play its characteristics and advantages of the power to extend the service life of UPS!

Fujian Quanzhou: private enterprises have entered the "low-carbon road"

Cheese battery

Cheese battery

In the journey of finding new energy sources, researchers have developed a cheese-driven fuel cells - in fact, is the use of whey, a byproduct of cheese-making process. Commonly referred to hydrogen fuel cells are fuel cells, and the study's goal is to make waste plant through the organic waste directly into electricity, thus restoring the waste of energy.

Whey is rich in lactose, Patras University, Greece, according to the biochemical engineer Georgia Antonopoulou introduction, lactose can be fuel cell culture medium in the digestion of bacterial decomposition, which directly generate electricity. Microbial fuel cell is not a new idea, but in recent years, as a way to waste water treatment and power generation at the same time to attract enough attention.

Whey is rich in organic matter, such as direct emissions, the environment at risk, many governments have enacted strict legislation will require plants to process it. According to Dr. Antonopoulou, occupied in the production of cheese whey liquid milk 70% of capacity, so even a small cheese factory, will produce up to the year 4,000 tons of whey. Microbial fuel cell can not only help the industry deal making cheese whey; breweries, farms, food processing plants, and even sewage treatment plants can benefit from this technology.

The traditional fuel cell makes use of catalytic fuel oxidation substances such as hydrogen, and produce positively charged ions and negatively charged electrons. Cations are attracted to a subsidiary electrode, electrolyte through the diaphragm or isolated electron, so that it can not move closer to the electrode directly to the cation, so that free-swimming electrons through wires running to the subsidiary electrode, resulting in current.

Microbial fuel cell principle is similar, but stored in the catalytic reaction chamber microbial fuel cell. In the anaerobic environment (ie, no oxygen present), whey through these micro-organisms to provide nutrients to metabolic, biochemical reactions in the cation will be produced, making the current generation is possible.

"In theory, microbial fuel cell can use any kind of organic-driven," the British Bristol Robotics (300,024, stock it) Laboratory head Chris Melhuish explains, "All you need to do is to make as a fuel organic matter and microbial culture medium appropriate pairing. "Melhuish spent many years of using Dr. wastewater to drive the robot, this process is not simple.

Nevertheless, Antonopoulou Ph.D. has proven that through the use of bacterial culture medium obtained from the water and with diluted whey as a fuel, such fuel cell performance with the use of processed fuel quite. The question now is the energy output of the fuel cell only microwatts magnitude, barely able to charge the phone. Meanwhile, the waste water treatment remains a long way to go.

Beginning, Antonopoulou Ph.D. and her colleagues found that they made the Cullen fuel cell efficiency (an electron into the circuit for generating a number of measures) is very low, only about 2%. This is because the microorganisms contained in the whey which is also absorbing electrons, so pre-killing by these impurities in the whey, and now they Coulomb efficiency to about 25%. They also vowed, through the design using a new fuel chamber so that the electrode surface area can be further improved to increase the power of the device.

Now the biggest problem is the lack of such fuel cell materials research and development investment. In the present case, as Antononpoulou Dr. Dr. Melhuish researchers had to use conventional fuel cell reference design of the electrode. If these problems can be overcome diverse and that the technology can be widely applied to industry, the microbial fuel cells have the potential to produce as it was the anaerobic fermentation tank of gas produced from waste as generated enough energy. If given enough time, the technology will be able to mature slowly, so as a high-quality cheese.

U.S. main battle tanks, the installation of high-power electronic devices will increase the fuel cell

Since the service since the 1980s have been many improvements, with export earnings to support further upgrades

States Army's main battle tank contrast, the U.S. M1A1 "Abrams" has absolutely proud of the capital, a strong interest and escalating artillery electronic system to maintain a leading position as a fellow in the Jiao-Jiao person. Currently, the U.S. is considering the electronic equipment to further tap the potential of M1A1.

More powerful fuel cell energy

It is reported that the Army plans to M1A1 "Abrams" main battle tank to install an advanced hydrogen fuel cell components, to provide electricity. Tank car research chemical engineer Steven Electra website published an article in the Army, said that although fuel cell technology is still in the experimental stage, but the U.S. Army engineers have been in a number of civilian vehicles were tested. Army wants this kind of battery is installed in the "Abrams" tanks for vehicle computer systems, fire control systems, sensors and other equipment to provide more power.

U.S. Army in the 1980s equipped with M1A1 tanks began to replace the old M60 tank. M1A1 tank about 10 meters, 2.4 meters high and weighs 63 tons, equipped with a 120 mm smoothbore gun and a 12.7 mm coaxial machine gun. In power, equipped with a AGT-1500 gas turbine engines for the M1A1 has brought a 72 km / hour speed. M1A1 tanks through a number of improvements in service after the upgrade, most recently, the United States has asked for the General Dynamics M1A1 integrate remote weapon station technology. General Dynamics of foreign claims, the system includes laser rangefinder and thermal imaging devices, than the existing M1A1 tank fire control system also advanced. Some analysts pointed out that, because of the high-power electronic devices equipped with more and more, only the U.S. military hopes to develop long-lasting fuel cells, support the M1A1 to enhance combat capability.

Comprehensive upgrade to ensure absolute advantage

In the country's main battle tanks in active service, M1A1 truly exceptional. Depleted uranium armor, the introduction of German technology to produce 120-mm smoothbore gun coupled with depleted uranium penetrators to both offensive and defensive. With a strong interest gun, M1A1 in the Gulf War of 1990 will be Iraq's Soviet-style armored forces played doomed to failure.

In the 21st century, large-scale tank battle has become a thing, roadside bombs and rocket-propelled grenade into the U.S. military's new nightmare. To this end, M1A1 has also undergone a transformation, begun on the installation of reactive armor side skirts, and installation of fence at the rear of the body armor, and a 12.7 mm machine gun integrated remote-controlled weapon stations, in order to enhance battlefield survivability.

M1A1 has become a popular commodity on the international market. Not only Kuwait, Saudi Arabia, Egypt and Australia, a large number of purchases, even the newly established Iraqi government forces have ordered 140. With the sale proceeds of tanks, the United States to continue to upgrade their equipment models. U.S. Associated Press reported June 25, pointed out that the sale to Saudi Arabia and Egypt, after a large number of M1A1, U.S. Army can get adequate funding and equipment more advanced M1A2 tanks.
