Taiwan solar cell industry may need to be integrated

Thursday, November 26th, 2009

For the rapidly developing field of solar power component manufacturing, Taiwanese companies will go through a difficult period, and may be forced to integrate.
Cause of the problem faced by these enterprises are in the middle of the supply chain, and can not be vertically integrated. These enterprises are not used in the production of polysilicon solar panels and batteries dell Inspiron 6400 battery, but also basically not involved in the integration of solar systems.

At the same time, they also are low-cost rivals from mainland China and local large companies squeeze.

While the demand continues to grow, manufacture or assembly of solar cells Taiwanese company profit margins decline, in addition to the merger and the creation of their own brand is no alternative.

Yuanta Securities (Yuanta Securities) is expected next year, Asian demand may double solar cells, an increase of more than 50% of the world.

Yuan Tai Securities in Hong Kong, an analyst Min Li said the solar industry will eventually become a commodity industry, because the entry threshold is very low, which is the mainland’s rapid development of the reasons why the dell Inspiron 5150 battery company must therefore develop their own brands, At the same time, if the scale is not big enough, it will be difficult to survive.

Taiwan’s 2008 exports of the total power 900 megawatts of solar cells, with a total value than doubled in 2007, reaching 3.15 billion U.S. dollars, in the global market share of 11.6%.

Motech Industries Inc. (Motech Industries Inc., 6244.OT), chairman of the left yuan Huai River (Simon Tsuo) expects 2012 global solar cell shipments will reach 25 billion watts, an increase of 4 times higher than in 2008. In terms of volume of shares Motech of Taiwan’s largest and the world’s eighth largest manufacturer of polycrystalline silicon solar cells.

But Ben Asia Securities (Primasia Securities), said strong demand led to oversupply, and the surplus situation will continue until 2011, although shipments growth, but the solar cells next year, prices will decrease by 20% -30%.

Taiwan is still in the middle of the supply chain, both upstream enterprises rely on battery production raw material polysilicon, but also need to rely on downstream dell GD761 battery systems integrators. Systems integrators because of its brand, able to obtain a higher profit margin.

Huai Yuan Zuo said that as the supply of polysilicon has a right to control and access to government loans, Suntech Power Co., Ltd. (Suntech Power Holdings Co., STP) and Yingli Green Energy Holdings Limited (Yingli Green Energy Holding Co., YGE), etc. Mainland companies to be vertically integrated.

Li Yuan Tai Securities, said mainland enterprises lower costs than European companies 33%, 22% lower than Japanese companies.

Solar photovoltaic module assembly companies Jing Mao Company Limited (Kinmac Solar Corp.) Chief executive Mr Sunny Wong scales (Robert Huang) said that at present Taiwan has more than 20 battery module assembly business, total capacity of about 600 MW, which numbers must be of at least one billion watts in order to have the economies of scale, would be difficult to compete on price alone.

However, due to concerns about climate change, it seems bound to promote solar energy industry, giving rise to several decades of rapid growth, a number of Taiwan-funded enterprise intends to take action.

These companies include the chip giant Taiwan Semiconductor Manufacturing Co., Ltd. (Taiwan Semiconductor Manufacturing Co., TSM, referred to as: TSMC) and UMC (United Microelectronics Co., UMC), flat-panel maker dell TD347 battery AU Optronics (AU Optronics Corp., AUO), and chemical giant Formosa Plastics Corporation (Formosa Plastics Co., 1301.TW, referred to as: Formosa Plastics). These enterprises are in the development of the green energy business.

Recently, TSMC CEO Rick Tsai (Rick Tsai) took over a new department, the department specializes in developing solar energy and clean technologies such as light-emitting diodes.

AU Optronics May set up a systems integration company, while in September to spend 125 million U.S. dollars through the acquisition of a Japanese silicon wafer maker M. Setek Co. 15% stake in the upstream and downstream expansion of the business.

Industrial Technology Research Institute (Industrial Technology Research Institute), said analyst Jay Wang, TSMC and other companies could lead to solar energy industry has undergone tremendous change, because these companies have strong financial strength, capable of vertical integration.

Excess photovoltaic polycrystalline silicon as a whole does not have bottomed out

Wednesday, November 25th, 2009

Vote against the wind sector, pay close attention to the PV industry, the problem of excess production capacity, Suntech Power’s chairman Shi Zhengrong 23 in 2009, said the annual sony VGP-BPS8 battery meeting of entrepreneurs, from the photovoltaic materials to see that this year 50% of the polysilicon to rely on imports, the overall production capacity and to see is not excessive, but the low-end excess production capacity exists locally.

Although polysilicon pricing is still hovering at 50 yuan / ton in a lower position, but from the industry perspective, have shown the trend bottoming out. Third-quarter earnings of listed companies related to the chain upward trend in the more vigorous, and the market outlook continues to rebound can be expected.

This year 50% of the silicon material to rely on imports sony VGP-BPS8A battery 

“The financial crisis triggered the foreign photovoltaic market is shrinking, leading to a temporary excess capacity, combined with the domestic market capacity can not be released, leading to a surplus of domestic production capacity. While the technology behind the product not meet the quality requirements are the main reason for partial excess capacity. “Shi Zhengrong think.

Zhengrong Shi said, “China will Huyou, planning capacity is to build capacity 10 times, the building of capacity is the actual capacity of 10. Every company wants to the table before the Government power, the results to the government to mislead, in fact this year we have 50% of the also rely on foreign imports of raw materials. Therefore, the current so-called excess capacity is in fact low excess capacity, inefficient excess capacity and low-quality excess capacity sony VGP-BPS9 battery. ”

He said that in the first half, about 30% of Suntech’s excess capacity. However, beginning in July, Suntech not enough production capacity to the end products are sold out, even the expansion was too late.

In fact, from the Suntech earnings perspective, Shi Zhengrong, and there is no “Huyou” the industry. Suntech in 2009 third-quarter sales and net profit surge in the second quarter were 85% and 342%. Suntech optimistic forecast for 2010 shipments will surge 75 percent compared with 2009, the company also plans to be the end of 2010 production target from the current 1GW raised to 1.4GW.

PV Enterprise bottoming out

Although polysilicon price would still hovering at 50 yuan / ton in a lower position, but from the industry perspective, has been showing a bottoming out trend, countries photovoltaic companies sony VGP-BPS9/B battery, especially in the third quarter results for Chinese enterprises have greatly increased the chain. KGI 23, released a report that the high return on investment demand has picked up guide, industrialization season will continue until the fourth quarter. Since 2009, PV prices have fallen sharply, making investment in PV systems in Italy, France, Germany, Spain and other countries look attractive return on investment, including subsidies for the German market in 2010, raising rates may lower upfront investment boom , coupled with high international oil prices and other favorable factors, the global PV industry demand for the third quarter of temperature and strength of a strong return to the main manufacturers shipments and revenue than in the second quarter of substantial growth, Chinese companies rely on cost advantages, performance, the sharpest rise shells.

In addition, the National Development and Reform Commission and other departments have 10 iron and steel, cement, plate glass, coal chemical industry, polysilicon and wind power equipment industry, as excess capacity, in principle, will no longer approve the expansion of production capacity projects. This will make polysilicon sony VGP-BPS9/S battery spot prices to stabilize, the future reduce the risk of rapidly falling prices of related companies constitute a beneficial effect.

KGI that, while PV corporate profitability has not yet fully recovered, but some companies in the third quarter and fourth quarter shipments were a record high of basic industries have been leaving the bottom plate with compensatory growth opportunities for PV. Among the many PV companies, with economies of scale, group strength, technological innovation, the regional advantages and other firms will be the better choice.

From the industrial chain, at present, involving a listed company polysilicon feedstock, including Leshan Electric Power, Chuantou energy, TBEA, Jiangsu Sunshine, shield an environment, industrial chain sony VGP-BPS9A battery covering raw materials to protect the battery has Tianwei change, CSG, aerospace mechanical and electrical focusing thin-film batteries are Tuo New energy, Vosges stake in polysilicon furnace cast anchor there refinement technology.

Countries of concern PV electricity price policy

For photovoltaic electricity price policy, Shi Zhengrong insisted that only 1.44 yuan PV installed capacity of electricity can be achieved large-scale sony VGP-BPS9A/B battery,sony VGP-BPS13/S battery development. “The price is not less than 1.44 yuan a company can make money. When an industry or infancy, if the business process can not be profitable, what kind of power and capital to continue to expand the scale? How can we continue to invest in R & D, to study more and better technology and products? “

A solution to a good laptop battery capacity drop another way

Notebook battery capacity to solve the decline ways and means of Jiemi

My notebook is basically mounted on the books, and one to prevent accidental power outage, resulting in their work wasted. Secondly, can also play a role in protecting your computer. Every night I go to bed are holding a computer, the battery will look at a movie or novel (with wireless network), and then sleep. However, a long time (soon two years). Found that battery life has dropped. The next test with software and found that the capacity decreased by 45% every time only with an hour of Tingbu Zhu. Later found a number of ways, no way to lose 45% of the capacity to find them again.

Last month, read the article about cell phone battery maintenance, so I hut ton open. In accordance with this method, you can restore the capacity of the battery to 90% or more, and is now used for nearly a month, there is no Han problems. Now to come out to share with everyone, hopefully more useful to everyone. Specific approach is to first inside the laptop battery power exhausted. The more the better with a clean. Then get some good absorbent paper (I am using a napkin), the battery pack up. Then put the battery in the freezer of frozen whole box to (not frozen), put 3 days, and then take it out 2 days at room temperature decentralized. To wait for the battery thaw. Such as the battery return to room temperature, and then thrown into the refrigerator. Two days later to take out at room temperature for 3 days, put into the laptop charging. To pay attention to when installing the battery on a copper surface and get all the clean water. Is full, you re-use the software under test to see if the battery capacity of more than 90% of the back. Time and battery life of up to two and a half hours of. Very practical bar!

HP previews able fourth-quarter earnings

Tuesday, November 17th, 2009

On the heels of announcement its accretion of 3Com, Hewlett-Packard aswell gave a bastard blink at its fourth-quarter earnings.

Though not appointed to clearly advertise balance until November 23, hp laptop battery said Wednesday it expects to address acquirement of $30.8 billion for the division on balance of 99 cents per share. (Excluding ancient charges, it would accept becoming $1.14 per share.) While acquirement was down 8 percent compared to the aforementioned division a year ago, balance were up from 84 cents per allotment in the fourth division of 2008.

Analysts were assured balance of $1.12 per allotment and acquirement of $29.8 billion.

“Solid beheading collection aberrant achievement for hp 338794-001 battery this quarter, fueled by cogent advance in China,” HP Chairman and CEO Mark Hurd said in a account Wednesday. “We are carrying on our action and are able-bodied positioned traveling into 2010.”

The aggregation aswell aloft its angle for 2010. For the aboriginal quarter, HP is ciphering $29.6 to $29.9 billion in revenue, and balance amid $1.03 and $1.05 per allotment excluding 13 cents per allotment laptop battery of after-tax costs and accuse accompanying to restructuring and acquisitions.

Nano-particles of organic dye solar cells open up new fields of application

Monday, November 16th, 2009
The new solar laptop battery, the above can be embodied a variety of colors and patterns, the smarter of them to well integrated into the architectural design. The new solar cells for windows covers not only the sun can also generate electricity.

Key elements of the new battery pack is an organic dye and a combination of nano-particles, which can convert sunlight into electricity. The component is the translucent form, making it more suitable for dell Inspiron 6400 battery  integration. New solar cells developed by the Fraunhofer Institute for Solar Energy Systems.

Solar prototype battery pack is amber, but it is quite possible there are other colors, and even in the printed image or text so that it can be used as decorative elements. This approach has opened a new set of application areas: solar panels are not just that as the roof of the building, but can also be applied to Windows, using this new  olympus charger technology can not only prevent the direct sunlight in Inside the building, and can generate electricity.

“We do not believe that the dye solar cells is a traditional silicon cells competitor” physicist FraunhoferISE
AndreasHinsch said. The module prototypes only achieve efficiency by 4%, what is and apply it to the roof performance compared to silicon solar cells crystalline. On the other hand, dye solar fujifilm battery have an obvious advantage is that integration in the positive.
  
Complexes between the physics of glass in both cell membranes using nano-and screen-printing technology, which makes it possible to get the images you want printed on the new solar cells, solar cells made of the new curtain wall Glass can be given more effective decoration and design, such as multi-company logo color.

Dye solar panels is still a prototype. The new technology has brought a particular challenge or two layers of glass outside the cell membranes must be sealed to prevent air in the destruction of reactive samsung battery substances. Fraunhofer experts have a solution for this problem, they are not the same as the competitors, the use of plastic polymer instead of a fine glass powder, to this end, the glass powder is screen printing and middle of the glass, rising temperatures, the material gradually softened glass, began to show its cash to bridge the gap between two glass, the temperature around 600 degrees Celsius. In a variety of weather conditions, tests have shown, the solar cells can work thousands of hours, but the possibility of long-term stability has not yet been officially confirmed.

How to identify the good battery and bad battery?

Friday, November 13th, 2009

There are many laptop battery in the electronic market, a large number of substandard products into the market, including many original batteries counterfeit, take many potential to consumers. For non-professional consumers, we suggest the customer select the notebook battery following to the next tips:

1. Check packaging
Battery packaging should be sealed anti-static bags, anti-static foam lining, which is to protect the basic configuration of the camcorder batteries.

Battery packaging should have a bar code serial code. Bar code is provided by the factory management of commodity standards to identify the authority logo.

2.check the appearance
Batteries should not be scratched or the appearance of the old sense, or readily available second-hand goods renovation as OEM Sony Camcorder battery.
Battery case should be clear parameters, performance, application of model identification.
Joints up and down the panasonic camcorder battery cover should have no marks have been opened.

3. Check the official commitment to the protection of that and after-sale

Formal professional laptop battery grade qualified products cylindrical canon camcorder battery, since the date of the factory, there are bonds for one year warranty. If you can not have this commitment, then the use of batteries and other materials may not be the quality of very qualified sub-grade batteries but batteries. At present the market with large number of obsolete Japan, South Korea and the poor sharp camcorder battery conversion, this product may seem cheap products are actually huge profits, as well as the normal use of notebook computers much damage, the explosion will be serious personal injury caused to consumers.

Notebook battery fully charge and discharge error

Friday, November 13th, 2009

Notebook computer equipped with the original battery, after a period of time after use, there will inevitably be the case of standby time. Some users said: “depth with repeated charge-discharge method, be able to resume the performance of the battery, thereby extending the battery life.

To a correct understanding of this issue, start a notebook about the type of laptop batteryused. As we all know, in 1995, before the production of notebook computers are basically used to power nickel-cadmium batteries. In the use of such batteries, if not the correct way of charging and discharging, the battery will have a “memory effect”, thereby reducing the battery’s actual capacity, the elimination of this “memory effect” is the best way to repeatedly charge and discharge depth manner. With the emergence of nickel-hydrogen batteries, battery capacity has improved significantly, but the “memory effect” did not completely eliminate the shortcomings.

In recent years, lithium-ion batteries in notebook computers has been rapidly increasing, largely as a result of lithium-ion batteries have been the elimination of the “memory effect” problem, it is used repeatedly to restore the depth of dell Inspiron 6400 battery charge-discharge performance of the method is not applied. But why lithium-ion battery capacity or the will to reduce the problem? Have a fundamental reason for this situation is used in notebook computers and the original lithium-ion battery in the built-in battery management systems.

Battery Management: At present, in notebook computers, almost all adopted the “battery management” and “charge-discharge control” of two chip-level management systems. The “battery management chip” placed in the notebook computer itself, the chip registers in the memory of the computer used in the capacity of lithium-ion dell Inspiron 1501 battery, operating temperature, ID serial number, charge-discharge state, the cumulative number of charge-discharge and other important information. In the use of these data, the need to constantly refresh the actual situation. The battery built-in “chip control charge and discharge” the most important role is to monitor and control the battery charge and discharge the entire process and be documented.

Charge: Lithium-ion rechargeable battery the whole process is divided into “fast charge constant-current” and “reduced charge constant current” two stages. The so-called “constant current fast charge” means charge has just begun, the charge current and charge voltage to follow a fixed battery terminal voltage gradually increased until they reach their nominal voltage of the charging method. When the dell Inspiron 1520 battery terminal voltage has reached the standard value, the controller will automatically turn into “reduced charge constant current” phase, when the charging voltage will no longer continue to rise, while the charge current to follow the battery capacity is rising gradually diminishing, and eventually reach zero, so they all completed a dell Inspiron 1521 battery charging process.

At the same time, the charge generated by the process of charging voltage, current and time data curves will be recorded in the dell Inspiron 1525 battery“charge-discharge control chip” of the memory. “Battery management chip” is through access to th

ese data, calculated by the sample data such as battery capacity, which is, in Battery Information in numerical Wh read.

Fixed: After repeated charging and discharging the Dell Inspiron 1526 battery after use, its built-in chip in the charge-discharge data will of course be changed. If at this time “battery management chip” has no chance to re-read the newer, more complete data, it calculated the battery capacity will not be accurate of course, to the user the feeling seems to be reducing the capacity of the  dell Inspiron 6000 battery, and the fact that the actual capacity of the battery has not really reduced. Some bring their own brand of rechargeable laptop management software working principle, the process is in charge refresh “charge-discharge control chip” memory of the data, thus ensuring the “battery management chips,” the correctness of calculations.

A close look if you have the use of laptop manuals, will be found that “a month in the use of computer time, should make a full  dell Inspiron 6000 battery charge and discharge operation” note. Its main purpose is to use the depth of charge and discharge the way to amend the charge and discharge control chip register data in the curve so that the battery charge control and battery nominal capacity and the actual situation, as a result the correct value of the battery capacity.

the Art of Laptop Battery Maintenance

Thursday, November 12th, 2009

We all own more battery powered products than ever before, and in most cases those laptop battery are rechargeable. Laptops, music players, phones - they all have rechargeable power packs, almost all of them using lithium.

These batteries don’t last forever. No matter what you do, their capacity to hold charge will decline over time, typically down to 80 per cent after 12-18 months in the case of laptop batteries.

That’s a range, not an absolute cut-off point, so how can we make these batteries last as long as possible? Ignoring the exceedingly rare risk of a fire, is there any way to ensure we get the best performance from our portable power supplies?

Follow some basic rules, and the answer is yes.

The model usage pattern is the mobile phone. Of all the rechargeable laptop batteries we’ve used, the ones in phones have always proved to retain their capacity longer than batteries in laptops, cameras and MP3 players. It takes a long time, generally speaking, for a phone battery to reach the point where no matter how long you charge it, it goes from full to empty in a very short space of time.

Contrast that with the netbook battery sitting next to us, which although less than a year old will discharge from full in under 20 minutes. That’s with the netbook just sitting there, screen on, connected to the internet. It should last eight times that.

The keys to dell battery longevity are regular usage and making sure cells are recharged before they become empty. Phone batteries typically take a couple of days to run down and tend not to be constantly on and off the charger during that period. Rather than waiting until the phone has so little power it switches off, most handset owners recharge their phones when they get a low-charge warning, usually around ten per cent capacity.

This ensures a steady, even cycle of charge and discharge, and if there’s an operating condition lithium batteries respond well to it’s regularity.

The apple laptop battery won’t, of course, give you two days of usage, so it’s not necessarily practical to follow that charge-discharge-recharge pattern exactly, but you can get close. Make sure you regularly use your laptop on battery power. Don’t work on it with it always plugged into the mains.

If you do use the mains as your primary power source - as you might well if the notebook’s your main machine - at least make sure you use your laptop on  hp PB992A battery power a couple of times a week. This is what we didn’t do with the netbook. It has stayed attached to its AC adaptor for most of its life, with the battery barely being used.

The connected battery will charge to 100 per cent and then the battery pack’s electronics will ensure the cells receive no further charge. At this point, the biggest threat to the battery is heat from the laptop’s internals. Make sure your laptop’s vents don’t become covered. Beyond the heat generated by its operation, a laptop can safely be left connected to the mains.

There’s no harm in removing the battery from a laptop that’s going to stay connected to the mains for a while. Just make a note of the optimum hp 371785-001 battery storage conditions - more on this later - and don’t inadvertently yank the power cable. With no battery, there’s no back-up for your laptop’s memory.

Apple machines are an exception, and others may be too: they auto-underclock the processor when the battery’s removed, so despite being connected to the mains, they won’t run at full strength. We think that’s daft, but that’s Apple for you.

When you use your laptop on dell Inspiron 6000 battery power, make sure its charge drops to at least 80 per cent. But don’t let it drop to zero. Depending on which operating system you use and how its power settings are configured, you’ll get a low-power warning first and, later, your machine will sleep, hibernate or shut down.

At this point, your battery should still be charged to 5-10 per cent of its capacity, and you should now charge it, whether you want to continue working or not. If you’re not going to be able to do so for some time, make sure you’ve saved your work and your laptop’s shut down or hibernating rather than sleeping. These two modes turn the laptop off whereas sleeping just keeps it ticking over, but power is still being drained and you run the risk of emptying the battery.

Completely draining the battery is a no-no. Battery manufacturers and laptop makers say that it’s a good idea to drain the dell Inspiron 1721 battery as far as the laptop will allow every so often and to then charge fully in order to synchronise the various capacity monitors within the power pack and the laptop. That ensures that your capacity read-outs are as accurate as they can be.

There seems to be a consensus that daily-use laptops don’t really need this, and certainly not on even a monthly basis. Occasional-use laptops, on the other hand, may benefit.

Eking out the charge while your using your computer on  nikon battery power is simply a matter of disabling Bluetooth and Wi-Fi if you don’t need them, making sure your system spins down the hard drive when it’s not required, and - perhaps best of all - dimming the screen’s backlight.

If running to empty or never discharging at all are to be avoided, high temperatures are right out. Batteries’ inevitable capacity decline can be slowed by keeping the panasonic digital camera battery cool

According to website Battery University, a battery kept full will see its capacity drop by six per cent after a year if it’s kept at freezing point. Kept at 60°C, however, the same battery will lose 40 per cent of its capacity to hold charge after just three months.

At 25°C, you’re looking at a 20 per cent capacity loss after one year. Since your working environment is likely to be less than 25°C, the reduction will you see will be a little less than that, and by making sure the canon charger is used regularly and evenly, you should be able to delay the point at which the battery has only 80 per cent of its starting capacity to 18 months or more.

Cycle logical: check your battery’s recharge count in Mac OS X

Hot-running laptops will have the reverse effect, so if your notebook’s like that, consider buying a cooling stand to help draw heat away from the machine and panasonic battery. Don’t keep your laptop in a hot car cabin, or in direct sunlight.

If your laptop’s going to remain unused for a long period, keep it cool. Never freeze it, but sticking the battery in the fridge, for example, will prolong its life. Battery manufacturers recommend storing batteries with a charge level of 40-50 per cent.

If you do refrigerate a samsung battery, don’t start using it as soon as you take it out again. Leave it several hours to warm up to room temperature first. Rapid warming could cause condensation, and you don’t want moisture forming inside your battery pack or laptop.

If you have a spare battery pack handy, keep it cool and charged to 40-50 per cent of its maximum capacity until you’re ready to take it on your travels. At that point, charge it up and use it as often as you use the other battery, so they both undergo regular charge and discharge cycles.

Charge Cycles Explained

Battery longevity - how long the battery lasts rather than how long it’ll power a device from a full charge - is typically measured in cycles, with one cycle being a discharge from full to empty.

This doesn’t need to happen all at once. A cycle is reached when 100 per cent of a casio camera battery’s potential capacity has been taken, even if it’s charged up in the meantime. If you drain a battery by half one day, charge it back up, take 25 per cent the next day, charge it up again then drain it by a quarter on the third day, that’s one cycle: 50 per cent + 25 per cent + 25 per cent.

That might suggest the best way to eke out cycles isn’t to discharge the battery too much, but don’t forget, lithium-based canon battery chargerlike to be used, not left on 100 per cent all the time.

Laptop makers typically say a machine’s battery capacity will have declined to 80 per cent of its original capacity after 300-odd cycles.

 

Support skills for Electric vehicle battery

Thursday, November 12th, 2009

1. Dont store the Electric vehicle battery in powerless

It is prohibited that store the laptop battery in a state of loss. State power loss is the failure to charge battery in time after use. Stored in the battery state of loss, it is prone to sulfate and lead sulfate crystals attached to the pole on the board, plug the electric ion channels, resulting in under-charging, the battery capacity decline. Idle state power loss the longer the more serious battery damage. Therefore, the battery should be charged fully once a month when not in use, so that the battery can keep in a good health state.

2. regular inspection in time

In the use of process, if the continued line of electric vehicles in a short period of time a sudden drop in mileage of more than ten kilometers, it is likely that the battery pack at least one battery cell appears broken, soft plate, plate active material shedding phenomenon, such as short-circuit . At this point, the battery should be repaired in time to the professional bodies to check, repair or distribution group. This can be relatively extended life dell GD761 batteryto maximize cost savings.

3. avoid large current discharge

Electric cars at the starting line, manned, uphill, please use pedal power to help avoid a momentary high-current discharge. High-current discharge easily lead to lead sulfate crystallization, to the detriment of the physical properties of the dell Inspiron 6400 battery plate.

4. keeping right charging time

In the use of process, should be based on the actual situation accurately grasp the charging time, frequency and use of reference normal mileage situation and pay attention to the capacity of the battery manufacturers to provide the size of note, as well as matching the performance of the charger, the charge current to grasp the size of charging parameters such as frequency . Generally batteries are recharged at night, with an average charging time in about eight hours. If shallow discharge (charge mileage after a very short period), the battery will soon be full of and continue to charge-off charge will appear, and that leads to cell loss, fever, lower battery life. Therefore, in order to discharge the hp PB994A battery depth of -70% to 60% when an electric charge the best, the actual use can be converted into cycling mileage, according to the need to charge the actual situation, to avoid charging damage.

5. prevent exposure

Electric vehicles is prohibited under the sun exposure. Environment temperature is too high will increase the internal pressure of the battery cell pressure limiting valve automatically opens, is a direct consequence of the loss of water to increase the toshiba laptop battery, and battery cell over-activity of water is bound to trigger a decline to speed up the plate to soften, charging shell body fever, from drum shell, deformation, such as a fatal injury.

6. avoid charging plug fever

Charger output plug loose contact will lead to the phenomenon of oxidation, such as charging plug fever, fever for too long will lead to short-circuit plug charging, direct damage to the charger, lead to unnecessary losses. So when found out that the situation should be promptly or replace the connector to remove oxides.
