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.

Battery meter showing a notification that a battery might be going bad

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.

Battery meter showing power plans

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.

Companies running into the field of new energy

The new energy sector is becoming the focus of the market. This section not only in industrial policy to obtain specific support, in the capital markets also gained the favor of investors. It is in this context, many traditional industries have started to invest in listed companies into the new energy sector.

New energy industry is currently involved in two major business, one of new energy power generation business, such as solar power, biomass power, wind power, the second is the use of new energy power industry, including lithium batteries, battery cars.

New energy vehicles

Jiangxi two listed companies, shares and river-motor Anyuan announced desire through cooperation into new areas of the energy bus. According to the notice issued by the two companies, the shares owned subsidiary Anyuan Anyuan buses and special motor Jiang, Jiangxi lithium new energy, new energy power giant Beijing Shenzhou four companies signed a "new energy production Yichun lithium bus agreement . " Among them, the body responsible for providing Anyuan bus and vehicle electronic control systems and vehicle assembly; Jiang motor and special motor is responsible for motor control systems; Jiangxi lithium can be responsible for the new bus manufacturing of new energy lithium co-ordination work; Beijing Shenzhou giant new power can provide the battery and battery management system, is also responsible for batteries and battery management system installation.

Jiang-motor-related charge, said the company can play to the advantages in the field of special motor, the lithium industry, upstream and downstream direction, the auto and electric vehicle drive motor assembly research and development, trial, but the contract had no effect on the current operating performance . Anyuan shares official said that the implementation of the contract Anyuan bus to enhance R & D capabilities, to promote the development of new energy bus company has products to help improve play a role.

Lithium Battery

Foshan Lighting is a veteran lighting manufacturers, Bell, chairman of the letter was a recent shareholders meeting, Qinghai Salt Lake Group in cooperation with the company's initial production of lithium carbonate project is about. In addition, the company through the acquisition of Landmark National Hi-Tech 20% stake in the new energy field formed a "development of lithium - lithium batteries - electric vehicle applications" a complete industrial chain.

Chung said the letter was, in Foshan Lighting has been successfully obtained four years ago to extract lithium carbonate technology, the company is expected to be completed within one year 3,000 tons of production capacity. Guoxuan Tech has a lithium iron phosphate cathode material and battery capacity, and has been successfully used in electric bicycles and storage batteries. Guoxuan Ankai Tech and co-developed 30 electric buses in Hefei, the beginning of time Demonstration. Foshan lighting that can take advantage of the upstream resources of lithium carbonate, lithium battery development projects for the future formation of lithium from lithium carbonate extraction to the production of lithium battery materials, and gradually form a new electric car energy chain.

Solar

CSG fields in addition to a generous investment in polysilicon, but also invest in a thin film solar cell with TCO conductive glass production lines. CSG's first annual production capacity of 460,000 square meters of thin film solar production line of TCO conductive glass was mass production of 2010 season, which makes CSG has become the first solar thin film photovoltaic cells with TCO conductive glass production capacity of the enterprise .

TCO glass is made of thin film solar is one of the key raw materials, global demand in 2010 will reach 25 million square meters. CSG is actively conducting TCO glass expansion project is expected to total production in 2011 will expand to produce 1.2 million square meters. CSG said it would closely integrated thin film solar cell technology trends, R & D has been differentiated characteristics of the product line.

The Vosges shares into the new energy field is a key project of solar thin-film battery components, Sun's chairman said on your company for the industrial transformation have high confidence.

Wind Power

Land of the direction of energy transition is the main business field of wind power. Land of energy through multiple asset sales, from a trade, machinery manufacturing-based industry trade manufacturing enterprises into the wind power industry, new energy-based enterprises. Company directed repurchase is completed, Shanghai Hong Chang Sheng Group became the largest shareholder, in Inner Mongolia Wulanchabu 400 square kilometers of wind farms, all production will form a 1,500 MW total installed capacity and annual power output 3.75 billion kWh production scale.

Cathay Nengyuan said the company is now focusing on the development of a project ---- Inner Mongolia Bayinxile 49.5 MW wind farm project, was in 2009 Xia Bannian construction, fan equipment purchase contracts signed in early 2010 has also been in Other work is in full swing them. It is understood that Cathay energy Bayinxile 49.5 MW wind farm wind power concession projects have been selected through public bidding to determine the Vestas Wind Technology Co., Ltd. 2 MW wind turbine, the two sides have signed a wind turbine procurement contract .

Industry point of view

New long-term healthy development of the energy industry

Recent decision-makers stressed the need to focus on strengthening the polysilicon, wind power equipment industry guidance, strict market access; for polysilicon and other new industries to establish and improve access standards, to solve the problem of excess capacity. This is the new energy industry is a major positive. Wind power, solar industry, leading enterprises will directly benefit from this industrial policy, and competitive market environment facing the situation will be greatly improved, the industry leader is expected to take this opportunity to further consolidate its dominant position.

After the domestic wind power market in recent years, temper, local wind power companies have to occupy in the global top ten three seats. To the wind as the representative of leading companies, on the one hand to obtain financing through the capital market expansion capital, but also begin the layout of the global wind power capacity market. We think this is the impact of slowing domestic price competition, global wind power market towards the correct course.

On the solar industry, the 2009 global PV installed capacity of new highs reached 7200MW. With the national PV industry to promote the implementation and support policies continue to lower the cost of electricity can be expected, the global PV market by 2014 demand will reach 30GW, the next five years remains at a compound growth of more than 30%.

The future of nuclear power industry equipment, the most important feature is full localization. At present, China can produce 300,000 with independent intellectual property rights kilowatt pressurized water reactor nuclear power plant equipment, the localization rate of 80%; basically have the complete set to produce 60 kw pressurized water reactor nuclear power plant unit of capacity, independent of the share may exceed 70 %. Next 10 years, China's nuclear power equipment market is about 418 billion yuan, $ 38 billion annual market capacity.

BYD's secret front: iron batteries will be put into mass production

Alleged breach of the new plant site was forced to a standstill, to postpone the return of A shares, Hong Kong stock price nearly cut, fund holdings, Morgan Stanley lowered sales expectations and investment rating ... ... BYD (52.65,0.85,1.64%, the economy through real-time quotes) ( 01211.HK) recent troubles.

At the same time, BYD in its field of solar power and electric cars are still, as always, a high-profile. Perhaps, in the individual this view, all the technical problems bothering the general will as he habitually overcome.

Compared with the above, BYD has been claiming that "nuclear weapons" iron battery will be put into production perhaps it was really fun to do.

This is outside of the much-anticipated years of BYD's "core technology", and BYD vowed to enter the solar energy and other new layout, is the secret of concentration of forces BYD front.

However, the mystery is indeed mysterious, but also in the outside world into question. Has always been known for its low cost advantage, technical research capabilities, it really can be the same as in the field of rechargeable batteries to help them continue in the new field of energy withering to take the lead, will not like it's known as "the world's first production dual-mode electric vehicle "F3DM general, but no one saw the thunder down?

After all, this over the years to attract everyone's attention F3DM, has been listed since March this year, sold only 20 units, which with its annual sales target of 1,000 units far.

This is more than a year ago for its claim to a large-scale production of iron cast a shadow over the battery production plans. After all, a secret front in BYD, whether it is iron battery, or solar cells, solar energy storage power plants, all based on large-scale electric vehicle based on sales.

BYD aware of this, perhaps after facing years of high-profile, it will eventually usher in the outside world a glimpse of its secret nature to look.

New energy expansion

"BYD is indeed building a 100 MW solar cell production line, but has yet to reach capacity production line, still in the commissioning phase." Mid-July, the PV industry, told the newspaper.

The source said, back in 2008, BYD announced to enter in the photovoltaic field, and to institutional investors, said polysilicon links in a "physical law" technology (a way to take high-temperature melting of silicon purification technology) - - "can reduce the cost per kilogram to $ 8."

Should the implementation, this cost would be subversive. In fact, until 2010, the most advanced silicon technology costs of $ 25-30 per kg. "BYD description of the 'cost' of solar prospects for we are operating to bring PV business of listed companies investor relations trouble." The source said.

Until the end of the first half of 2010, BYD service delivery in the photovoltaic cell responses to 320 kilowatts of products. This is almost the size of guinea pigs, a country of about 20 MW plant size also.

Newspaper learned that the first sign of BYD Battery Co., Ltd. is the American Solar Energy (SolarPowerInc. Referred to as SPI). SPI's main business of residential photovoltaic roof.

Shenzhen, a private, said they were not optimistic about the BYD use of "physical law" manufacturing polysilicon. "Not only is their team, the technical action is not obvious, but in the United States, Japan, there have been several solar companies to do the physical laws, later failed." Siemens is now relatively common (at high temperatures, a chemical method to purify silicon technology), physical method, while a short process, low investment, low production costs, but the disadvantage is that the conversion rate of instability, recession and rapid product and technology relatively immature.

For solar cell production status BYD, BYD, said: "On a lot of solar energy plan, the company now are not made public, and not convenient to answer." BYD public relations, a person claimed that "solar production line is started, not very sure."

This does not prevent the vision described BYD. In the solar business, BYD has a very large project - a message from the Shaanxi Provincial Development and Reform Commission, Shaanxi BYD plans to build 5,000 megawatts of solar cell production line. It gave himself six years to be completed by 2015.

In contrast, the domestic leading enterprises Suntech took eight years before they reach the current size of 1,000 MW. This means that, Suntech in order to "catch up" BYD, must raise 50% of the annual production capacity to 5,000 MW in 2015. Meanwhile, the PV market have the same annual rate of expansion.

As the world's largest market - Germany last year demand for 2,500 MW of photovoltaic cells.

Meanwhile, the BYD targets, Suntech is more than the "magnificent" - to build the solar cell industry chain.

In addition to production, technology and market risks, the news from the Shaanxi Provincial Development and Reform Commission, BYD is expected to invest in the project, $ 22.5 billion is the development of circular economy in southern Shaanxi ten projects.

Funds come from, BYD did not give an explanation.

However, although no solar cell results, but involved in the new energy industry, the success of the company in the capital market rally. In 2008, BYD began to spread on the market in the "low-cost polysilicon manufacturing" news. In 2009, BYD announced a solar cell project started in Shangluo City, the scale of 100 MW. In early 2010, came BYD want to build 5,000 MW scale.

The end of June this year, said the news from BYD, "a 100-megawatt production line will be formally put into operation, two 400 MW has started construction."

"'Will be formally put into operation' instructions not to do, that is, and new energy vehicles, like business, BYD uses campaign ahead." Broker a researcher said.

Time difference

BYD is studied under in more new business, but called "nuclear weapons" - is still only iron battery technology. After all, in the company's territory, the main industry is still the car, and thus extended to other business.

BYD-iron battery is called the "nuclear." Cited outside the curious, this is a core technology itself exactly how powerful, can mass production?

The reporter field survey found that, until today, the iron battery production base two projects are still construction sites.

This year, BYD shares soared up to 85 million.

Last August, BYD announced that electric car battery production base in Huizhou, Guangdong capital construction, "the battery can be mass-produced iron." At that time the company introduced two projects in construction in September 2008, and covers an area of 810,000 square meters. Phase II project that is BYD iron battery production base.

One year, BYD electric vehicle battery production base status?

July 14, 2010, newspaper reporter iron battery base in Huizhou scene - two project sites, the large tracts of land still loess overturned, dusty park, the site is basically a heterogeneous picture. And across the street from the excitement of a park scene compared to hurry here, do not see the workers wearing BYD tooling.

In the two corner site, the reporter saw "BYD Battery Co., Ltd. Huizhou base two 1, 2 quarters," the project license. Start date of November 11, 2009, completion date is July 30, 2010.

Corner of the park, part of the blue roof of the plant has been built. According to the workers introduced into the plant has equipment. Reporters tried to enter the film factory, but blocked by security.

Contact BYD Company newspaper, the responsible person, "the company has provided for the project base-iron battery is not currently open." A CCTV reporter said that CCTV has repeatedly requested access to iron battery production sites to visit, but the same was rejected.

Has been "secretive show people" BYD iron battery production line, started what will, lead to the outside world quite a lot of speculation.

April 2009, the battery company BYD Huizhou, for electrical appliances, automatic washing lines and other equipment for a number of tender. In July, the Daya Bay District Government BYD two industrial parks located in the "BYD Auto paint production project environmental impact report" for the trial.

BYD these initiatives seems to indicate that iron battery production line, step by step indeed. But so far, BYD iron battery two sites, most of the wasteland.

There is speculation that "nuclear weapons" iron battery "carrier" - the electric car has not yet reached the scale of production, or restricted-iron battery BYD main reason for large-scale production.

December 15, 2008, BYD announced its "world's first production dual-mode electric vehicle" F3DM listed. A year later, in March this year, an upgraded version of the car - "low-carbon version of" formally for personal sales.

Phase of product a year ago, "low-carbon version of" a piece of the roof to install solar panels. BYD said in addition to professional and home charging station charging outside, F3DM low carbon version added a third charge of solar charging this way.

However, since the sale of several months, as of mid-July, the car sold a total of 20 units. One month of June, only listed in the Shenzhen area of 12 units were sold.

This means that the electric car to be optimistic about the outside world until the mid-2010, BYD is still not sufficient to promote publicity in 2009 that the realization of large-scale production of iron battery. BYD is obviously aware of this, this, in addition to subsidies enjoyed sales of Shenzhen, as well as in Shanghai and Hangzhou to promote F3DM and E6, the company is located in Changsha, the base of electric buses, but also within the year production.

Path

BYD along the way, voices of doubt and applause go hand in hand. For its main focus on the question: what a significant reduction in cost, iron battery and electric vehicle technology available why the delay?

"Propaganda first," is the key external challenge BYD arrogant.

In the individual into the car business before the company is doing OEM rechargeable battery and cell phone parts.

In 2003, BYD Qinchuan car purchase, Wang declared that: "Do electric cars is BYD entered the automotive industry in mind. BYD electric cars do, is to make China's Three Gorges dam, the water turned into oil , so that all cities in China, like Tibet, is like the sky blue. "

In 2007, BYD entered the automotive industry is the fifth year, Wang has released rhetoric, issued a "Declaration of 2015 and 2025", respectively, for the "China first" and "the world's first" specific time. This year, BYD sold only 85,000 the year, car prices in the country are still not on the number row.

In 2008, F3DM models listed, so that became the domestic BYD electric vehicle technology leader. Although, the car was "shelved" until today has not achieved mass production, but BYD "upstart electric car technology" image is already set.

Concrete expression of new energy vehicles and "upstart electric car technology" status does not match. Until the end of 2009, 45 million units in BYD in total car sales, the proportion of the fuel cars accounted for almost all.

However, Wang's pursuit of electric cars, has successfully attracted a "Warren" Buffett's attention. Munger, Buffett's partner and even praised Wang, "This guy is simply a combination of Edison and Welch." "Warren" shares, the BYD shares rising steadily to $ 80 or more.

The delays for F3DM for personal sales, Wang Jun, a spokesman said BYD Auto: they do not want in the market environment and facilities is not ripe hurt the consumer market, BYD is willing to support national policy and other vehicles with lower prices make this market bigger.

BYD said the current market environment and facilities are not yet ripe, such as charging stations, charging pile set and other facilities is not perfect, also involved in power system communication, and strong government co-ordination.

Interestingly, in the "immature environment" under the constraints of BYD has introduced a new plan is more ambitious - "to enter the field of solar cells." BYD hopes in electric car, and then attach the solar cells.

Vertical integration

BYD to build solar cell production lines to make up for electric cars "car environment", the company has a new plan.

May this year, BYD Los Angeles financial district in the United States, set up a "car batteries and solar business" headquarters. Chairman Wang said at the scene, "I want every family to spend solar panels," and claimed that the company's next goal is to "expand the U.S. market", and then, and then shift the focus to hybrid and electric-powered vehicle.

July 13, BYD new energy into the house. Teamed U.S. KBHome, green residential building in the United States. Allegedly, this set of residential solar energy technology, battery technology and LED lighting in a number of new energy technologies.

This may be BYD "expand the U.S. market", and also indicates the future direction of BYD solar battery.

However, BYD This time together to create a new energy with only 5 residential units, and the use of new energy technologies, there is no commercial. In China, only used in BYD own "future Village". "The future village" is BYD in Shenzhen, Ping Shan base two villas, the company's technology in this lab.

At the same time, BYD's under the IT field - rechargeable batteries, will be this year, further increasing battery product application portfolio for the development of electric vehicles and energy storage power station and other new business areas to prepare.

BYD Company portrayed to the outside world is a new energy business in addition to IT and vehicles, to enter the third area. New energy business, including solar power, storage power stations, new energy vehicles, solar cells.

BYD said the company will use the "vertical integration" of low-cost model, transplanted to the new energy sector.

July 22, BYD insiders told this newspaper, "the company does business in preparation for home appliances," but, the person said, "several executives at the meeting explained that this business is currently not allowed to reveal."

Can be expected that the business should also be BYD appliance chain in a ring.

In addition, the Shenzhen Municipal Government to seek industry in inland after the transfer of Foxconn, BYD more support in the field of electric cars, BYD to give great support. Its two electric cars F3DM and E6, respectively, for maximum 89,000 yuan and 12.9 million in subsidies.

According to this understanding, BYD to support the new energy vehicles, a taxi company in the local government specially selected 40 5-star driver, driving 40 BYD new energy vehicles. Elements of these drivers can not pay the money, the monthly wages of 6,000 yuan.

Excellent environment due to BYD's battery of new energy vehicles - every taxi driver can only run 400 km per day. BYD new energy battery charge is divided into short, medium and long full charge. Among them, the fast half-hour full charge is 60%, and long you need to charge full 6 hours. Shenzhen taxi drivers the practical experience, or to bring new energy electric cars BYD reputation.

Capacity expansion in new business while in mid-July, the Ministry instructed the Shaanxi Provincial Department of Land and in conjunction with the prosecution, and severely punish illegal land BYD shares Plant Xi'an incident, in order to cast a shadow over the business this year, BYD.

It is understood that in order to "shock 800 000," the sales target, Xi'an BYD expansion project started last year. Currently, the project was forced to run aground.

BYD existing capacity of 500,000 vehicles, of which the capacity of the facility with 300,000, but this year sales target of 80 million. According to data released by China Association of Automobile Manufacturers, sales of BYD first half of 2010 was 28.5 million. After the event, the industry worried that the company had sales of cold car will once again intensified.

For some time, BYD was Fidelity holdings, Morgan Stanley lowered sales expectations and investment rating, A-share listed the main surgeon who UBS Securities Asia Chairman Cai Hongping also announced the departure. July 14, BYD announced that plans to issue A shares extended for another year, until September 7, 2011.

BYD has a whole lot of good new energy vision, however, the car business, profit alone is not enough support. As a "technology upstart," BYD, how to promote the new energy carrier, the outside world remains to be seen.

Volkswagen intends to launch in 2013 the first electric vehicle to market

Reuters German website reported July 20, Volkswagen intends to market in 2013 the first electric car.

Volkswagen CEO Winterkorn announced Monday in the United States, in 2012 hybrid vehicles, electric vehicles by 2018 sales will increase to 3% of total sales. Venturi said the main problem now is the electric vehicle battery is too expensive, the average cost per kilowatt-hour 500-1000 euros. He hopes to reduce the price of the battery, the "batteries not only to smaller, lighter, more to be cheap."

Valve-regulated battery life because the base station and measures

This causes the base station of the current process of valve-regulated battery capacity decline, shortened life expectancy for various reasons, the analysis and discussion, and propose improvements.

Keywords: VRLA battery life improvements

From the current base station battery situation, widespread decline in battery capacity too fast, short life, even just 1 to 2 years battery capacity is only a nominal capacity of 30% to 40%, some only 10% to 20 %, and most of the base stations 1 to 4 years after the battery is running, its capacity is only 50% of its nominal capacity, far less than its design life, and exchange the battery compared to the same bureau station, its service life is also greatly lower maintenance standards used by the battery, as long as the battery capacity drops to 80% of its nominal capacity, its life will end, they should be replaced, this causes the base station on the battery capacity dropped too quickly, analyze the causes of reduced life and explore, and propose relevant measures for improvement of this hope for all operators to help. This refers specifically to VRLA batteries battery.

Excellent form of solar photovoltaic cells supply and demand imbalance

PV industry suddenly from winter into spring last year. From the fourth quarter of 2009, the PV market recovery, the first half of this year, forms an excellent.

Photovoltaic industry from upstream of the hot demand for polysilicon raw materials can be seen two. According to the Investment Advisory Industry Research Center, the latest data show that GCL in the first five months of 5713 tons polysilicon production and sales, 300% more than last year. Only from January to May, China imported a total volume of polysilicon to 1.55 million tons, with 7007 tons compared to the same period last year, an increase of 121%. According to public data, as second only to solar PV production base in Jiangsu, Zhejiang, the first quarter of this year, total exports of 4.73 million solar cells, an increase of 250%.

Capacity in the global market continues to expand. In some European countries to step up not only launched the PV power generation projects, the United States, Japan and other countries are also active layout. China also announced in June this year the second batch of photovoltaic power generation tender, amounting to 280MW, while the last is only 10MW. Jiang Qian said, according to forecasts, this year's global PV installed capacity will be twice last year, which for the PV industry in China has brought new growth points. After the economic crisis, a leading international photovoltaic companies have slowed down the pace of expansion also makes the product supply and demand in an unbalanced state.

Bump advance solar energy technology based on light-driven market

"New energy", especially the "solar energy industry" in recent years attracted a large number of investment companies. Industry has also experienced a rapid development of the whole industry chain is becoming mature. Many IC companies are optimistic about the future of new energy industries, and gradually began to expand related product lines, while some manufacturers are using the advantage of years of accumulated technology, naturally cut into the emerging markets.

Embossing technology (O2Micro) since its inception in 1995, sold 15 years more than 1.1 billion chips. This is a focus on specific areas of IC products and solutions company, can be described as quite good. This created by the Chinese, the main high-end custom-made design of multinational semiconductor companies to leading technology and professional services industry has been praiseworthy. Especially in backlight technology and battery management technology, O2Micro (O2Micro) always walk in front of the industry.

LED backlight is still substantial growth

Bump Technology Intelligent Lighting, executive vice president, Dr. Lin Yonglin description: With the display technology development and innovation, dominate the market for decades-old CRT monitor has gradually been lighter, thinner, more power to replace the LCD monitor . But even if the LCD display and "unified" Today, LCD panels used in backlight technology has been evolving. As early as ten years ago, O2Micro (O2Micro) began to put LED backlight driver IC development. According to incomplete statistics, such as big screen TV backlight applications, O2Micro (O2Micro) CCFL drivers have become market-driven solutions, while the LED backlight driver market, O2Micro has achieved very good results, which with the "advance, as early as the layout of" inseparable.

It is worth mentioning is that the current CCFL drive a major supplier of chips, in addition to the Roma but also have bump technology, which in the U.S. patent and technology licensing is also from the embossing technology (O2Micro). LED backlight on the laptop drive in great demand, Dr. Lin Yonglin that: This year may have more than 85% of the laptop screen, LED backlight technology will be applied. In the large-screen LED driver, the Japanese and Korean manufacturers in the market to go forward, and embossing technology (O2Micro) has also begun on a large screen area and Japan, South Korea's major brand manufacturers to cooperate.

Very close to the PV market strong

From the DC / AC inverter, battery management to the backlight, the accumulation of core technology enables embossing technology (O2Micro) to enter the PV market is particularly the process more natural. Battery management is the key, how to get more battery life. For multi-cell applications, if one or two cells is broken, the whole system would be affected. For large-scale use of photovoltaic systems in the current lead-acid batteries, O2Micro (O2Micro) solutions can monitor each cell's voltage, while adjusting the charge and discharge, to ensure the voltage balance, thus extending battery life.

Dr Lam stressed, O2Micro (O2Micro) has the advantage of technology and experience accumulated over the years and will continue to derive the PV industry, such as solar-powered LED lighting systems and so on. When it comes to batteries and power management, sustainable development will bump technology. It is reported that the domestic photovoltaic industry leader and a bump technology (O2Micro) formally signed a business cooperation memorandum, I believe that this strong combination will lead the PV industry into a more brilliant era.

To protect the charging electric buses, Hefei charging stations to be to build 3

To address the issue of charging electric vehicles bus, the city plans to build three large-scale charging stations. Currently, three large charging stations will have been identified.

This year, the city seize the national grid distribution in the national strategy for building charging stations the opportunity to actively and provincial power companies have signed a strategic cooperation agreement charging station construction, and construction of charging stations for the national grid to provide a "green channel." It is understood, the city is planning to build Shaodaying bus charging station, charging Yaohai bus station, charging station Public Transport Company to build a pure electric passenger car charging pile of about 500.

According to reports, Hefei new energy battery bus rental model is used, the battery maintenance by the manufacturer responsible for rent by the government allocated to the bus company, bus company and then allocated based on usage the battery manufacturer. This year, the city has actively introduced the "financial leasing" business, bought the battery by financial leasing companies, leasing companies use public transportation, maintenance by the manufacturer is still responsible.

Currently, the city as the country's 13 energy-saving and new energy vehicle demonstration pilot cities, has already put in 30 electric vehicle demonstration operations, opened the country's first electric bus lines. By 2012, the city put in energy-saving and new energy vehicles will reach 1400.
