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.

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.

Battery warranty for one year six months or “strike”

Industry: new battery for six months after the renovation of damaged cells is norm

Mr. Zhang, the provincial capital to buy a brand of electric vehicle batteries, with no electricity for half a year, and had business commitments this year falls far short shelf life, Ms. Wang to buy another brand of bike, 10 months after Battery capacity is significantly less than to the business gave her a free replacement battery for a refurbished battery, very poor. Recently, this reporter received a lot of readers of the phone are reflected in electric car battery problems. Why do battery electric cars are more problems? Reporters have conducted some research.

readers to reflect:

After six months battery warranty for one year but can not charge

Mr. Zhang, the provincial capital in March last year to change a battery electric car, 36 volts, and spent more than three hundred dollars, but less than electric Juji six months, and I never ride no more, the battery can no longer charge. Zhang told reporters, when buying batteries, the business commitment to ensure that the battery can be used for one year. But when he hurriedly ran to find businesses, they found that the business has been empty. Mr. Zhang provided by merchants battery is definitely suspect a problem, when he asked around friends, you have the battery life of the warranty period of one year to challenge, “many of my friends and I have encountered the same problem a few months on battery not uncommon uphill climb. ”

The battery is new for the “old”

And compared to Zhang, Wang lucky. Last year, Ms. Wang bought a brand of electric car, 10 months later, the battery there is a clear lack of capacity, greatly reducing the mileage of the phenomenon, according to the standard warranty period of one year, Ms. Wang also rushed to the requirements for dealers new battery. Dealers said the can to replace the battery, but Wang found that not only looks new for some of the old battery, but after use, or the emergence of the same problem. Wang questioned the dealer, the dealer told her that after six months can only be replaced to maintain the battery, that is, the old battery refurbished “new” battery, which, Ms. Wang said it is difficult to accept.

Industry Secret:

There are two main reasons for reduced battery life

With these readers’ questions, the reporter interviewed the electric vehicle industry, the provincial capital, a senior person, the person told the reporter, resulting in reduced battery life of electric vehicles, for two reasons, one is the electric vehicles commonly used lead-acid batteries, life expectancy is only 500 charge and discharge; the second is the user overweight speeding, making the battery discharge current is too large, damaging the battery life. “Subject to technical constraints, the current widespread use of lead-acid batteries, can only charge and discharge 500 times.” Remind the public that the industry, if the electric car does not run out of battery power, do not frequent charging. Meanwhile, the electric car designed load capacity of only seventy to eighty kilograms, the design speed is generally about 25 kilometers, driving in this condition, in order to ensure a year of use, if the public often with people or cargo, road time and speeding driving, and will definitely hurt the battery life.

According to this industry sources, in general, well-known brands of electric vehicles, an optional battery quality is relatively good. Some brands of electric hybrid vehicles, the competition for the market, then to compete with low-cost, quality of the selected battery is not good. “Some battery manufacturers, care for immediate benefits, as cost savings, more money, they cut corners, so many electric vehicles use batteries, but the quality is related.” Six months later, the battery is the norm for maintenance

The source told reporters, according to national standards, the warranty period, the battery capacity falls below 60% of the original can be replaced, but the data must be obtained after a scientific test, that is not braking, not climbing without people, do not turn on the lights in the case shows the data, and electric car industry in accordance with the unspoken rules, businesses will change after six months to maintain battery, replacement batteries in electric vehicles, the business keeps on saying that the battery replacement for one year In fact, a new battery before the battery replacement for six months, half will be replaced to maintain the battery, so-called “maintenance battery” is actually the old battery renovation, the effect is certainly less than the original battery capacity and mileage, the industry revealed that this is their norm, the battery is a consumable, the factory did it out of cost considerations.

CASE reminder:

The two sides should be clear “three guarantees” responsibility

Reporters learned from the Provincial Consumer Association, complained of several categories of electric vehicles, which is part of a considerable number of complaints about battery capacity, reflecting the mileage and the product description promised a large gap, there are some after-sales Service does not regulate the lights and electric cars, carriages, speakers, batteries and other parts of the lock quality complaints. Relevant department official told reporters, because electric cars did not explicitly state the “three guarantees”, the end of 2006, Consumers Association of Anhui Province, Anhui Province Franchise Association Professional Committee of electric vehicles jointly issued a “consumer dispute resolution Anhui Electric Bicycle approach, “clearly sellers, special repairer, producers of electric bicycle repair, replacement, return (three packs) of after-sales responsibilities and obligations, the battery warranty period is one year, if there is leakage or less than 60% of capacity failure should be repaired and replaced, but the official said, for the exchange of in the end is to maintain the battery or new battery, and not clearly defined, should be subject to agreement between consumers and businesses.

Therefore, the Consumer Association reminds consumers to buy electric cars to try to buy a brand of electric cars, buy electric car, the dealer should be observed there is no special maintenance station. Some shops do not repair to the factory for professional staff training, technology is difficult to ensure, together with parts failure, service is difficult to keep up. Ask for a car to pay attention to after-sales service warranty card, invoice, and warranty for all parts written specifically to avoid future dispute. Also, do not believe in the verbal commitment to the business, maintenance, service agreements or written materials to be included in the invoice form, so that there is a dispute as evidence.

Energy giant market ahead of the layout of Beijing charging station

Despite the popularity of electric vehicles is too early, but the attractive market potential to attract energy giant, charging stations ahead of the layout of the market.Reporters learned yesterday, Sinopec (600028, stock it) Beijing Petroleum Branch has been reached with the group of the first joint venture agreement, will work together to build electric car charging stations; while the national electricity grid has announced an ambitious month of “enclosure” program, in 27 provinces, municipalities, comprehensively promote the 75 electric vehicle charging stations, which intends to build Beijing 5-7 large-scale high-charging stations.

According to reports, wait-listed Sinopec Beijing in the first section of new energy technology Co., Ltd. registered capital of 50 million, will protect Beijing’s large-scale electric vehicle applications.The company will use the conditions in the petrochemical refueling stations, converted into a refueling charge integrated service stations, and plans to expand this business model to a comprehensive, Hebei, Tianjin and other areas.

Sinopec executives said the city has a very cramped space station, all new charging facilities is not realistic.However, compared with the power companies, the existing gas station network advantages of the system is very prominent. “Electric vehicles operating scale, consumers can charge the battery to the Sinopec gas station, the staff will focus to a large battery charging station charging, fully charged and then inform the consumers to get in has risen significantly, stations throughout the city, you can consider part of the network turned into a charging station. ”

With ordinary gasoline and diesel vehicles, twelve minutes to complete the different fuel, electric vehicle charging more slowly.With electric buses, for example, time-consuming professional for half an hour fast charging station can charge enough to power 60%, full power is required 45 hours.Taxis and family car, the fast charging stations at least 10 minutes to charge from 50% to 60% capacity.Thus, large-scale operation, the car waiting in line at gas stations charge, will only increase traffic congestion.

In the new category in the energy range of vehicles, hybrid vehicles, electric vehicles are considered the most realistic conditions, the technology path, but also China’s auto industry to reach the world advanced level of a breakthrough car.According to the Ministry of Science launched last year’s “10 City, 1000″ program, three to four years to develop 10 cities each year, less than 1000 in each city launched a new energy vehicles to carry out demonstration run, the scale of operations to foster the industry of electric vehicles of the foundation, which hybrid and pure electric vehicles will be the main vehicle.2012, domestic Demonstration of new energy vehicles will reach 60,000, the Ministry of Finance during this special subsidy will be up to 200 billion yuan.

Beijing is undoubtedly the focus of the new energy model city car.As early as during the Olympic Games, 595 electric vehicles in the Olympic central area and the surrounding regions had run 3.71 million km, transporting passengers to 4,417,000 passengers, the largest in Olympic history to achieve electric vehicle demonstration runs.At the time, supporting the construction of Olympic area of 5,000 square meters, the largest international electric vehicle charging stations.Since then, this temporary removal of charging stations, the Olympic central area of operations 50 electric buses in Beijing is currently the main bus station charging station charging, and continue driving on the streets of Beijing.

Municipal Science and Technology responsible person said, Beijing will be the new energy of pure electric vehicle demonstration fleet dominated the year 1000 will purchase electric sanitation vehicles and 200 new energy bus.Currently, electric vehicles are Xicheng sanitation pilot, its low noise, no pollution, improve the sanitation workers operating environment.By 2011, electric vehicles will account for all the city buses and sanitation vehicles, one-third.In addition, the City Commission by letter, Municipal Development and Reform Commission jointly issued by the automobile industry revitalization program is also proposed, will strive to achieve before the end of 500 demonstration electric taxi operators.

However, pure electric vehicles, especially electric vehicles, scale of operations, first of all have convenient charging outlets, and the charging station network layout is also directly determines the speed of electric vehicles into the home.Professionals worry that charging network construction, electric vehicles, especially electric taxi operators will face a severe test.In addition, the battery specifications, interfaces are not unified, the battery performance decay faster than expected actual battery life and other issues, will affect the marketing of electric vehicles.

“Days” of domestic battery industry, lead dancer

Changxing County Tianneng Power International Group last June 11 a successful IPO in Hong Kong main board. Historic moment in the market, who is also vice chairman of the China Battery Industry Association and Zhejiang Battery Industry Association, the company chairman Zhang Tianren claiming to be “the happiest people.” He said: “The enterprise market, the once dream-and this not only indicates the battery industry will speed up again, ‘days to’ is also facing a second venture.”

Founded in 1986, “days” is a small village factory, the late 1990s, pollution-free enclosed maintenance-free valve-regulated battery electric vehicles successful professional development, so that the “days” finally won a major national well-known electric car manufacturers trust and establish a solid relationship sales network throughout the East, and even radiation.

A business to sustainable development, and only constant innovation. In 1999, the “days” set up “Eternal Battery Science”, then, has set up a “high-performance environment-friendly battery Changxing Research and Development Center,” and with Zhejiang University to establish a new battery research and development center, so every year number of new products to market. Only the last three years to develop new products, nearly 65 provincial, national new products 3, 45 national patents. “Days” in the production of continuously upgrade the industry, is actively preparing to produce nickel-metal hydride, lithium ion batteries, new battery project.

Technological innovation and industrial upgrading, so that day to become the largest group of battery supplier, since 2001, annual production and sales growth of 200% or more. Up, by the “days” of the electric car batteries account for 50% market share.

All along, Zhang Tianren are so that the brand is the business to enhance the strength, reflecting the value of the carrier. In 1999, the second national selection of electric bikes start of the race specified mileage battery products. Then little-known “days” are sent to selected participants of the battery, who knows “days” to send the parameters of the selected battery products are eligible, higher than other brands and impressed the judges. Therefore, the “days” was chosen as the country for two consecutive terms battery electric bike mileage competition only designated products.

This year, the “days” proposed a “stable primary market, secondary market development, training end-market” positioning, marketing and management through a comprehensive sound system, strengthen the marketing ranks, increasing after-sales service network to provide consumers with more attentive service, so consumers really feel the “days” the brand’s unique corporate culture and brand appeal, and further enhance the visibility of days to the battery.

“Now the day can be the battery, even if the price 10% higher than similar products, or in short supply.” Days Renzi Hao Zhang said, “days in the past year the Group achieved sales ranked first in the industry, the electric bicycle battery market share for 8 consecutive years ranked first in the country this year, ‘days to’ declare known trademarks in China in three years, determined to recreating a ‘days to’ for the nation to seek a more powerful battery industry, broader right to speak. ”

New energy battery recycling is a long way to go green car challenge

New energy vehicles, electric vehicles in the stage are, and will continue to be used as a hot topic of discussion. This is so because it has been wearing a “green” hat. Zero-emission electric vehicles, it seems that people find the car from the manufacture of carbon dioxide into the sky towards the path of environmental protection. Automotive electric shock, the best of our state to pursue it?

Policy, car prices of double support

In 2009, China’s auto market performance, let us see the policy for the automobile market sales curve a powerful force. In the new energy, it is understood, are in the pipeline and is expected to be released in 2010 China’s new energy policy, including vehicles, is being organized to develop the performance of pure electric vehicle conditions to seize the commanding heights of world standards. It is reported that the state’s favorable policies of new energy vehicles will also be launched in the near future, people will buy electric cars expected to be 6 million in subsidies. In addition, the United Nations agencies will be held in March 2010 to revise the global automotive standards, including hybrid and electric vehicles globally harmonized safety standards.

Started to manufacture batteries and electric vehicle research and development has been at the forefront of BYD Needless to say. January 21, Zotye 2008EV hit the domestic market first mass-produced electric car flags. This month’s North American Auto Show, BMW Group’s global debut of the BMWConceptActiveE electric vehicles. Ford also announced a high-profile, will invest 450 million U.S. dollars for electric vehicle research and development production, according to incomplete statistics, as of now, there are hundreds of domestic and foreign businesses to invest in R & D production of electric cars. There are indications that the technical line of new energy vehicles have quietly turned to electric cars in 2010, new energy vehicles to enter the complete “shock” of the era.

Environmental protection, requires prerequisite

Energy use up clean, but its manufacturing process is also clean it? At present, China’s coal-dominated energy generation, followed by hydropower, nuclear power’s share is small. In 2003 the country’s total power output, thermal power accounted for 82.9%, 14.8% hydropower, nuclear power accounted for only 2.3%. Coal-fired power plants in the production of electricity, the emissions of carbon dioxide is much less than fuel vehicles. However, as we like, straight up the number of electric vehicles, the carbon dioxide emissions is not a small figure. A report released last year, has pointed out that if Britain’s 27 million cars are converted to electric vehicles and charging every day, then, the United Kingdom than it is now the power supply must quadruple to meet the demand. While figures show that car ownership in China will exceed 130 million this year. So, China’s power supply must be multiplied several-fold? I am afraid that is not a simple multiplication and division will be able to calculate the results. The coal is non-renewable resources, coal power generation is still not smooth the road.

Development of western China in recent years, is speeding up hydropower development in the western region, the “Plan”, China in the 21st century, half of the energy structure of power has the potential to increase in the share of hydropower. We hope so.

Battery recycling is a difficult problem

As we all know, the battery contains large amounts of heavy metals, acids, alkalis and other substances. In normal use, these substances are encapsulated in the shell, it will not cause harm to the environment and the human body. But when the battery was abandoned, due to the long-term effect of mechanical or corrosion, making the battery and other heavy metals and acid leaked, it could cause serious environmental pollution problems. In addition, some batteries, after the acquisition of plant acquisition, only a simple removal, whichever is useful for some, but will the rest of the discarded into the environment. The same may lead to serious environmental pollution. If you can establish a unified recycling system for recycling technology is not perfect or energy consumption, cost too much, it is recommended a centralized approach to deep landfill. But still the best way is to use reasonable recycling technologies, and avoid waste of resources to achieve sustainable development goals.

Thus, the use of electric vehicles is far from our imagination come easy. Want to complete environmental protection, we long way to go.
