Tips for saving laptop battery

A battery, can work from the power supply, laptop and desktop is the difference between the largest one is the so-called “portable use”, so the sony vgp-bps9 battery, sony vaio vgn-fz battery itself is the most important parts of one of the notebook, whether cost or volume weight, are accounted for in a notebook in a large proportion.

As with all batteries, notebook batteries are half consumables, the status with the use of time and gradually decreased, as long as you use, the battery will keep the wear and tear, the so-called use and maintenance of skills, it means as much as possible the potential to play a larger battery, and reduce the battery because of losses caused by use of time. In addition to new ones, the not in use six months after the battery is also like new, in fact, more than 30 times in the charge and discharge, the battery’s state began to decline.

Battery saving tips

First, take a look at how to make battery life a long time as far as possible:

Method 1: CPU deceleration. If your machine does not have built-in power management, when using the hp pavilion dv2 battery, hp pavilion dv7 battery, the XP’s power management set to “Max Battery” or “Portable / Laptop.” So that when the machine was found when using the battery will automatically reduce the CPU speed, it saves a large amount of electricity. The higher frequency processor, the greater frequency of lower magnitude, but also can save more power.

Method 2: Reduce the screen brightness. This and the use of comfort Paradoxically, the more power the lower the brightness, but brightness is too low not look comfortable, personal experience is that about half the brightness more appropriate place. Of course, if you can accept it, you can also adjust the brightness was lower. In addition, the larger screen size, brightness, the greater the impact on power consumption.

Method 3: the right to set power management. You can accept in the context of the hard disk and screen time to enter standby or hibernation settings were as short as possible. Many of my friends would ask, is it choose to enter “standby” status is good? Or “sleep” state is good? Which of the two more power? The answer is to use as the case may be. In fact, the difference between the two: when the standby system will save the data to memory, this advantage is the short time the machine wake up, wake up process is also less power consumption, but in standby process, the machine in order to maintain data in memory, will slow consumption of power; sleep time, the system sucked the data saved to disk dell studio 1535 battery, dell studio 1737 battery, do not consume after, but when entering sleep and wake up a lot of electricity to be consumed. Personal experience is that if the leave within one hour of computer, standby power than sleep, if the time left, the way is relatively dormant power. Of course, the power saving mode may be “off”, huh, huh!

Method 4: as much as possible off the external equipment. Including PC cards, infrared ports, wireless LAN, with particular attention to best not to connect USB hard drives and USB optical mouse, many people do not know that USB device is very power of two. If you can, even the best drives are not used.

Method 5: improve cooling. If the cooling efficiency, the machine would continue to operate the cooling system will consume additional power. Simpler method is to use the machine chess books or booster, in between the desktop machine and leaving about 1 cm of space, so the air flows easily. If you have the summer mat to sit around the water bag on the better latitude c610 battery pad in a notebook the following drivers can save a lot of fan power.

Method 6: Cancel screensavers, use pure black wallpaper. Unless your screen saver is the system that comes with “Windows XP” logo that, or cancel it, because the complexity of the screen saver will consume additional power. If your application without the need for ongoing, then the screen (for example, play music and download), simply close the screen, the “closing the portable computer” is set to “no”, then close the screen, the machine will continue to run, or to background set to black screen, so you can save pixel TFT-LCD display drivers of dell vostro 1310 battery, dell vostro 1510 battery electricity (the black pixels for the default power state), but if your operation will be constantly changing images on the screen, will not achieve this on a black background The role of the saving.

Method 7: Choosing and using software. When choosing software, try to select those resources relatively low occupancy, low CPU utilization and memory footprint, which means less power consumption, when using the battery as much as possible not to use memory-consuming huge “monster class” software Otherwise, when the physical memory is exhausted, the system uses hard disk as virtual memory, hard drive and CPU power will be part of the hurricane.

Method 8: Avoid use in high and low temperature battery. suitable temperature range is from -5 degrees to 30 degrees Celsius, higher than this temperature, the battery self-discharge will increase the battery time Bianduan, Er lower than the temperature, the battery lithium own capacity will decline Fahui not normal time should have the power.

Battery maintenance tips

1. Do not use as often as necessary and sufficient. If the battery has less than 70%, do not hurry to charge it would be best to travel into the 10% recharge, long-term injury with the use with the rechargeable dell latitude e6400 battery, dell latitude e6500 batteries will make the maximum capacity of the battery can not play, after fully charged, can remain AC power supply, the current laptop has a battery control circuit, not like nickel-cadmium or nickel metal hydride that would overcharge.

2. Should be stored in a suitable environment. Ideal environment is 18 to 24 degrees Celsius dry and dark environment, very sensitive to direct sunlight in the hot environment, if long-term need, the best charge to 40-50% and then wrapped in plastic bags saved.

3. Regularly complete charge and discharge time. And the general view that is different from the total charge and discharge actually can not improve battery capacity, but you can refresh the fully charge and discharge control circuit of the set, it realized that the actual capacity of the battery today, so we can be more reasonable to use the battery capacity and can be modified for example, shows 0% charge can also use the half-hour of such problems.

Recycling used batteries should be paid

The battery, it is a common thing in life, the necessities of life, the environment is gradually becoming a “killer” - one on the 1st battery, if the rot in the ground, you can make 1 square meter of soil permanent loss of use value lower than toshiba pa3634u-1brs battery, toshiba pa3728u-1brs battery, a Button batteries actually make 600 thousand liters of water to be contaminated drinking water is equivalent to the amount of a person’s life of battery. In this regard, CPPCC members Shenyang, Liaoning materials Sales Co., Ltd., chairman of Chia Tai Ha Fengxia suggestions: Paid recycling used batteries, not only can effectively solve this problem, but also to further enhance people’s awareness of environmental protection can be described as double benefit from APple A1021 adapter.

The status quo in Shenyang produce 30 million tons of waste batteries

Kazakhstan Fengxia said that at present only in Liaoning, the annual consumption of dry batteries in around 550 million, non-battery-generated about 1.5 million tons. The national annual production of 10 billion batteries, annual consumption of 156,000 tons of zinc, 226,000 tons of manganese dioxide, 2080 tons of copper, 27,000 tons of zinc oxide. At present, Shenyang, produces approximately 30 million tons of used batteries, the amount recovered was only 66 million, about 20 million tons. “Some experts have told me that one on the 1st cell of toxic substances can make one square meter of land permanent loss of use value, while a button dell vostro 1310 battery, dell vostro 1710 battery, if thrown in the water, which contains toxic substances killing 60 million liters of water Body of pollution, and that a person’s life is equivalent to the amount of drinking water.

“Kazakhstan Fengxia said, thus bringing the health issues will also be particularly prominent, but also to the state and society created a huge burden exceeding Apple MacBook Pro 15-inch or Apple PowerBook G4 15-inch Aluminum. Kazakhstan Fengxia that, in fact, there have long been used batteries and seriousness of the consequences of pollution hazards understand, but most people do not understand this process, the enormous cost - as derived from serious illness, therefore, lost labor, as well as the households to pay for high medical expenses.

Embarrassing waste batteries are “home” is hard to return to

as early as 2000, Shenyang Environmental Protection Bureau of Shenyang on public places, offices, schools, etc. to establish of 100 waste battery recycling boxes. At that time, the environmental protection departments are expected recovery of the amount of waste dry batteries can be a year to 120 tons. However, just less than six months time, that is, in 2001, which either form or durability are very good bins disappeared.

In June last year, when the lead at the provincial Environmental Protection Bureau under the Shenyang Environmental Protection Bureau has many locations in the city of nearly a hundred of waste battery recycling boxes, with little success by hp pavilion dm3 battery, hp pavilion dv9000 battery, some texture of metal recycling bins and even damage and stealing and selling. Street walking in certain streets, shopping malls battery, the reporter saw in the elevator at the side of an eye-catching promotional slogans written on scrap battery recycling boxes.

However, passenger traffic reached its peak in the afternoon the same day, almost half an hour’s time, waiting at the side of the press has never seen one this consumer will be used batteries in it. “Every day we will see recycling bins at most only 35 when the scrap batteries.” One of the shopping centers such as Battery, said the staff members concerned. In some Zhongjie and residential communities, the waste battery recycling bins where residents have long been used as a garbage running office. In this regard, the relevant departments of a person in charge, said: “Now, used batteries do have ‘family’ hard back.”

Survey of business sense

Compared with thte used batteries and Waste battery recycling box in which the embarrassment of a different, in some specific agencies, has become the meat and potatoes of used batteries.

1st,Nov, 8 pm just after a Dongling District of Shenyang City waste collection stations, the one wrapped Yanyanshishi name of the workers are nervously to a wide range of battery classification, with the attendant sold is located in the suburbs of Shenyang as a “factory.” There, indeed meticulous division of labor toshiba pa3593u-1brs battery, toshiba pa3594u-1brs Battery, it was dedicated to remove the battery cell, while others are responsible for cleaning, charging, welding circuit, the battery will eventually be processed puts on a new shell, and then rolled through the laminators … … a counterfeit battery production process It was so done.

Reporter has learned that these are waste battery recycling chain of the industry is the top specialist recycling of used batteries salvage station over Dell Latitude X300 battery. They usually will follow within the scope of the Waste Treatment Plant of Shenyang contact to about 40 yuan per kilogram price of the acquisition of used batteries, and eventually sold to “factory.” The plant eventually after a series of seemingly complicated process, such as magic, it will re-sell these batteries back to the market to Battery. In the market, such as the selling price of mobile phone batteries could reach 10 yuan to 20 yuan, even the most common of a dollar can buy 4 of the 5 or 7, the battery, the profit ratio is up to 20%. As for acquisition of electric bicycle battery, the rate can be up to 100% or even higher.

However, such a battery life there for how long? The mobile phone market in the small northern distributor mobile phone batteries with apple a1036 adapter, Mr. Wen told reporters: “is usually also a two months ago, consumers will obviously feel Daibu Zhu machine mobile phone, and often throw it away, and then buy one.

the proposed waste hp compaq 6510b battery, hp compaq 6910p battery recycling paid

Last year, the Liaoning Provincial Environmental Protection Office, the provincial committee through a letter of 6 departments have jointly issued a circular in 2012 before the end of a province-wide will form a set of well-organized, the system improve the management put in place various types of waste battery recycling system of governance over 45Wh Apple PowerBook G4 Adapterso that all the used batteries generated in our province have been dealing with utilization or placement to Toshiba TecraA5 battery or Toshiba TecraA6 battery. Upon request, our province will be set 50000 used batteries recycling bins, which will be set up at the Shen reach 9,000 or so. At the same time, Shenyang will also set up 2-3 recycling used batteries, each about one month to focus on the battery collection bins.

Moreover, as the Northeast Center for the sole disposal of used batteries, Liaoning Environmental Protection Industry Park, the next years in dealing with intravenous volume of waste batteries will be 2.2 million tons. Moreover, in order to solve the pollution problem of used batteries as, in Liaoning Province, Shenyang Environmental Protection Bureau and other related aspects of the strong support of the Tieling Fangsheng starts in Shenyang Environmental Protection Technology Co., Ltd. to establish waste asus a3000 battery, asus a32-f3 battery, asus a33-f3 battery recycling system work, and recycling of scrap the battery factory, harmless, resource processing.

However, through these sets of figures It is also not difficult to see that with each year of Shenyang will produce 30 million tons of used batteries, and future treatment capacity is only 2.2 million tons. A huge gap, but also will lead to more environmental problems. In this regard, Kazakhstan Fengxia said the first try in the original selling powerbook g4 power adapter ibook g4 adapter price based on the rate of increase in certain cost recovery as a waste batteries. Meanwhile, the development of trade-in you can enjoy the original price to buy a new battery requirements. In this way, as long as the purchase of new batteries each time to hand over the old battery, life only pay a recovery prices higher than Battery, consumers still use the original price. And then there are additional

collection points for used batteries, you can at school, property, neighborhood, all supermarkets, and district exit to set up a waste battery recycling point, to encourage waste battery recycling Apple PowerBook G4 15-inch Battery. Moreover, the environmental protection departments should ban short-lived regular cycle of low-cost production and sales of batteries, reducing pollution and emissions of the use of materials and the development of production and use of the battery does not contain harmful substances to sony vaio vgn-fz battery, sony vgp-bps8 Battery. In the end, the Government should encourage social policies and funding the formation of waste battery treatment industry, increase the recycling of used batteries manufacturers dealt with capital investment to expand capacity, increase the recycling of used batteries factory workers dealing with health-care costs, “so that an increase of the induction of employment opportunities, and increased the handling capacity of waste batteries, double benefit. ”

The concept of balanced battery technology and application

To the equipment in order to provide sufficient voltage, lithium dell vostro 1310 battery, hp pavilion dm3 battery pack is usually made by a number of batteries in series, but if the battery capacity mismatch between the impact will be the capacity of the entire battery pack. To this end, we lost the need for a balanced allocation of the battery. This article discusses the concept of balanced battery and some attention.

Li-ion battery pack is usually one or more batteries in parallel, each battery pack by 3-4 in series constitute a battery. This combination can satisfy the laptop at the same time, medical equipment, testing equipment and industrial applications of the voltage and power requirements. However, the general configuration of this application does not usually exert their maximum effect, because if the capacity of a battery in series with other batteries do not match will reduce the capacity of the Toshiba laptop battery pack.

Battery capacity does not match, including state-of-charge (SOC) and capacity mismatch / energy (C / E) mismatch. In both cases, the total capacity of the battery pack can only reach the capacity of the weakest battery. In most cases, the mismatch caused by the battery of the reasons for process control and testing are imperfect means, rather than lithium-ion changes in their chemical properties. Prismatic lithium batteries (LiIonprismaticcell) required more time in the production of mechanical stress, the battery is more prone to the difference between. In addition, the lithium-ion toshiba pa3399u-1brs battery, toshiba pa3399u-1bas battery will be because the introduction of new technology and the emergence of differences between the battery.

Balanced use of the battery SOC and treatment techniques to address C / E mismatch problem, thereby improving the tandem performance of lithium-ion battery pack. Through the initial adjustment process in a balanced treatment of the cells can be corrected mismatch problem, since only in the charging process can be balanced, and the C / E mismatch must be sufficient discharge to a balanced process. Even though a battery manufacturer for their products in terms of possible defect rate is very low, but in order to avoid too short battery life, we still have the need for further quality assurance.

The definition of a balanced battery

Working voltage of 6V or more portable devices powered used in series, in which case the total battery pack voltage of the battery voltage of the series and. Portable computer from the battery pack is usually three or four batteries together in series, nominal voltage of 10.8V or 14.4V. In most such applications, a single series battery pack can not provide the energy needed. The biggest battery current (such as 18650) provides 2000mAh (milliamp hours) of energy, and the computer required 50-60Whr (5000-6000mAh) energy, it must give each series of three battery cells in parallel.

Battery balance refers to the series are different hp compaq 6510b battery, hp compaq 6910p battery (or battery) Use of differential current. Battery packs in series for each of the current battery is the same as usual, it is necessary to increase the extra battery pack and circuit components to achieve a balanced battery. Only when the battery pack in the battery are connected in series, at the same time series equal to or greater than the three-tier battery when the battery will consider the balance. When the battery pack to meet all batteries have the following two conditions, we achieve a balanced battery:

1. If all the capacity of the the same as when their relative status as charging the battery when the balanced implementation. SOC is usually the current capacity and nominal capacity expressed as a percentage, therefore, open circuit voltage (OCV) can be used as a measure of SOC. If a battery pack is not balanced all of the battery can be recharged through the differential reach full capacity (equilibrium point), they will be able to carry out the normal charge and discharge without any additional adjustment, this adjustment is usually a one-off. Users when using the new battery, it normally takes a long time called for charging batteries, in fact this process, including a full release – charge. So that the process to minimize the load and the longest battery and reduce battery requirements of a balanced circuit.

2. If the asus a32-f3 battery, asus a3000 battery capacity is different from the same when the SOC that they are balanced. However, SOC is a relative value, the absolute value of the capacity of each cell are different. Different in order to make the battery capacity SOC the same for each of the battery charge and discharge in series must be used when the difference current.

Normal charge and discharge time of the initial charge and discharge more quickly, and required greater current.

When the battery pack in the battery is not balanced, it will reduce the available capacity, serial battery pack in the battery capacity will determine the minimum of the total capacity battery pack. Imbalance in the battery pack, a battery or some other battery will still charge the maximum capacity has been achieved. In the discharge when the battery is not fully charged battery will be released than other electric end, the battery pack due to insufficient voltage to the supply of electricity in advance.

Typically, the satellite a65 series capacity of the differences between the less than 3%. If the lithium battery packs in series to a battery of sub-standard, or placed in the package too long ago, after the electricity at a voltage difference of up to 150mV, so that the total capacity of the battery pack dropped 13-18%.

SOC balanced treatment

If the battery pack in the battery capacity of all the same, we will deal with the use of SOC balance. When all the battery SOC value at the same time we believe that the satellite a60-662 battery are balanced.

A single battery charge status is defined as:

SOC = C / CTOTAL%

The capacity of a single cell is defined as:

C = (i × t) mAh

In order to determine the capacity of a hp pavilion dv2 battery, hp pavilion dv7 battery, hp pavilion dv6 battery , we have the battery fully discharge and then recharge, and recharge in the process of current measurement at different time until it reaches the open circuit voltage of 4.20V. The best performance of the battery status in the SOC for the 100%, SOC 50% of the OCV voltage is often referred to as VMID, its typical value of 3.67V.

In order to give a different battery capacity so that they achieve the same SOC, to ask some battery charge / discharge capacity than many other battery, which must use the current differential. We will call this process of capacity / energy maximization.

Capacity / energy to maximize

Capacity / energy to maximize the battery pack means that all the series is set to the same battery SOC, even if they are different capacity. Time management in all SOC, the battery pack to maximize the output energy. In order to maximize the output energy, all the batteries have to be full of electricity. That is, all the battery SOC must be 100%. If the battery capacity is different from a number of battery charge / discharge the battery will be more than any other. For example, suppose there is a battery pack of three batteries in series, C1> C2 = C3. Balance of the battery packs are the only way to give a higher capacity battery (C1) to impose a differential charge current.

Discharge the battery pack must also be the case, otherwise, when the battery capacity to meet the minimum turn-off voltage, the entire tecra 8100 battery pack will stop the discharge, while remaining battery capacity of the other, thus reduce the total capacity. The long run, the capacity of the smallest dell latitude e6400 battery, dell latitude e6500 battery performance will be a recession than any other battery faster, go through a number of charge / discharge cycle will accelerate the loss of capacity.

Through the matching series battery voltage, high-capacity toshiba pa3356u-1brs will draw more current. Discharge when consumed through a balanced number of extra voltage, in the final when all batteries have reached 0SOC when obtained from the battery pack relative to the total energy balance will increase the former.

Usually cylindrical lithium-ion battery (cylindricalcell) are usually of better quality control, battery capacity difference of no more than ± 3%. Basically, more precise input capacity, the difference does not exceed some mAs (milliampere seconds). Therefore, the capacity is also the basic accuracy of the absolute value, SOC at the difference within a few percentage points.

Power lithium batteries as a new industrial investment

In recent years, electric vehicles, new energy has increasingly become an important direction of car development. Therefore, not only automotive business development of electric vehicles full of enthusiasm, as the core technology of electric vehicles, power lithium-ion sony vgp-bpl9 battery, sony vgp-bps11 batteries are also a number of parts suppliers to become a hot chase, more and more enterprises to join the development of lithium batteries for vehicle use , production. According to incomplete statistics, the industry has gathered hundreds of companies. So the influx of so many companies that have not industrialized areas, whether caused by excessive investment? Recent survey from a journalist, covering the situation, as a strategic new industry, battery industry, now that the excess investment still too early to grasp the key issue of investment Jiezou He accelerated structural adjustment, beware of investment bubble.

“For China, the development of electric vehicles are required to take.” Commenting on the development prospects of electric vehicles, the Department of Tongji University, Dr. Wei Xuezhe car express this view. He explained that currently, China’s auto output and sales volume reached 13 million, if not growth, in order to calculate annual sales of 13 million, 10 years is 130 million. 2020, car ownership in China will certainly have to break through 200 million, oil supply will be very prominent. In addition to electric vehicles, there is no other more effective solutions. Thus, while electric vehicles, or power, whether economic performance, have not reach the level of the traditional internal combustion engine vehicles hp pavilion dv9000 battery, dell vostro 1310 battery, the automotive industry have no choice. It is reported that electric car industry development has been included in the national “12 Five-Year” Plan.

It is increasingly clear that electric car development prospects, and aroused the enthusiasm for investment in battery industry. At the press survey, about 15 of the motive power of investment, only the total investment plan for 2009 reached more than 510 billion yuan. Among them, the largest investment of 300 billion yuan, at least for 50 million yuan to 1 billion -50 billion in mostly size. From the investors perspective, most of the battery, motor manufacturers, there are some cross-bank investors; in addition to business, many local governments. Like Tangshan municipal government, plans to invest 300 billion yuan, an investment is 100 billion and 2000 acres Industrial District, target group an annual capacity of 100,000 lithium-ion electric vehicle battery pack. Jinan, Shandong provincial government also plans also invest 5 billion yuan, is expected to reach 1 million units of electric vehicle battery production capacity, the first investment of 2 billion yuan. Which is the lowest investment Huafang power days, for 50 million yuan. And these are just part of the investment power lithium dell inspiron e1505 battery, dell latitude e6400 batteries.

From the international point of view, the market forecast that the global large-size lithium-ion batteries such as Li-ion battery market in the next few years a large number of surplus production capacity in 2015 will exceed 100%. The state subsidies will be stimulated more investment. In addition, most in developing countries is concentrated in the battery manufacturing field, and not the core of the material research and development. Really able to fully meet the technical requirements of vehicle manufacturers, with the consistency and size of capacity of qualified, low-cost battery supplier in fact still very scarce. Another authoritative report of the investigation agency pointed out: “low-end manufacturing capacity for repeated construction, lack of core R & D manufacturing technology, imitation, copy, emerging, and that is the status of the battery industry in these countries.”

The situation in China battery industry have been very prominent. From the investment scale, the current stake, to join the hp pavilion dm3 battery, asus a32-f3 battery industry, many enterprises, but the real is able to meet loading requirements, technical stability of the battery business is not over. 863 plans major lithium-ion battery supporting one of the BAK International Vice President Cui Ke believe that it is hard to say whether the excess investment in lithium batteries. On the one hand, the current electric cars have not really achieved mass production, the electric car market has not formed, the next in the end how much the battery is still ideas to solve. On the other hand, apparently a lot of investment companies, but the overall look very different scale of investment, enterprise strength varies greatly, not the same purpose, can be described as quite a mixed bag. Many of them really join the new energy automotive industry, but some are from chasing hot spots, but do concept to make money. Mobile power supply system to do a great degree of difficulty involved in security issues, including the testing cycle, including the determination of the program hp compaq 6910p battery, hp compaq 6510b battery and so it takes time, but also to the volume, it all depends on product quality, performance, or not so stable. The development of electric cars is not easy, and the need for improved technology, market cultivation and infrastructure construction, real industrialization is still at least a year or two. This requires that the battery companies to loneliness, but also with the development of electric vehicle technology, continuous improvement programs to increase investment. Strength of the weak or those who just want a quick kill no long-term plan left the company may not last the day, close down or switch to advance. From this point of view, real power to meet the demand for electric vehicles, batteries industrial enterprises are not many.

Based on the status of the lithium industry, industry experts believe that lithium industry to adapt to the development of electric vehicles, electric vehicles to meet the matching requirements Industry, will have a survival of the fittest in the integration process, and within a year or two the situation will be dell xps m1530 battery, dell xps m1730 battery clear.
