GM General Motors made in its production of new Volt electric vehicle in the same week, Honda announced that RD Director Masaaki Kato on plug-electric hybrid systems research, R & D investment in the near future will not be confirmed.

Toyota and GM are legitimate in the development of plug-electric hybrid system plugged rechargeable battery power efficiency and pure electric vehicles in the direction, but laptop battery  technology for Honda would not hold a lot of confidence, especially the unplugged mode really fit Commercial operation of the business have yet to do and, more recently, the price of lithium laptop battery  is still high, and there is heavy and has a low battery power, and so on, not the standard of goods.

So Honda decided to go its own way, by launched a few days ago FCX fuel cell car, Honda will own the future of alternative energy vehicles, car key, because only need to travel 448 kilometers hydrogen 4 kg, compared with traditional batteries, However, the expected Toshiba battery   technology and many more possibilities for the development of scientific and technological breakthroughs in the degree of difficulty will be lower. In the past two years have made some remarks, although Honda did not rule out the unplugged mode power source, but after a recent talk show, Honda fuel cell will be the core of alternative energy.

Now appearing on the market penetration is highest in the lithium-ion battery (Li-ion) As a result, this article will focus on lithium-ion laptop battery. Know your notebook battery you need to clarify the following parameters: battery capacity, rated voltage, the normal temperature and so on.

From the size of the capacity of the main battery to determine mAh marked by its Chinese name is milliamperes. Milliamperes have a direct bearing on the size of notebook batteries by the use of the time, but it can not be generalized. Is not to say that the notebook battery supply capacity of the greater use of more durable in actual use in the process of life were closely related to the ability of the notebook power consumption. We can imagine a notebook configuration, the higher the greater energy consumption, the greater the amount of running the operation of the passage of electricity will be the faster speed.

Is the normal operating temperature of the battery can work in normal temperature range, in the use of non-normal temperatures likely to be dangerous (explosive), as well as unnecessary trouble (leakage, all of a sudden power).

Date of production, which in some older models of notebook batteries will be in it directly in your piece of the battery can use the length of time, this is a decision of the normal use of compaq battery time for the important parameters. That is why we buy a notebook’s battery when it’s necessary to pay attention to the production date, even if the new batteries placed on the longer time of his life will be reduced accordingly. Expect to buy second-hand books for the users should pay attention to the aspects of the parameters.

How to tell what the parameters of this battery? From the picture we can see the type of battery used for Li-ion, lithium-ion battery that is. Rated output voltage 10.8V, for electricity 4800mAh. Of course, there are manufacturers, production, the normal operating temperature (0 degrees -60 degrees Celsius), and so on, the battery is currently used such a logo, you can enlarge the picture to the top of their notebook batteries some basic information.

The books of the external battery structure, we can only look at some of the above parameters of the internal structure of a lot of people believe that “dare” to understand. After all, the price of notebook batteries, or be called expensive.

In fact, the essence of notebook batteries and rechargeable batteries common no-like, but the major vendors have models for their appearance for the Presario 900 battery  case processing, so that if ripping out the laptop battery shell, its internal structure and Ordinary batteries do not have the distinction of any kind, that is the major mutual constraint brand notebook batteries commonly used is the biggest obstacle to major notebook PC brand among independent design.

A closer look at the internal battery, which is a few cells of the group series and parallel circuits, in general, by a single battery capacity and voltage requirements of notebook batteries bound notebook batteries generally used after the first series of parallel approach to ensure its Voltage and battery capacity, an analogy, if a nominal 12.5V, 4000MAh battery of the laptop, this is generally composed of: 3 by the single voltage 4.2V, 2000MAh of batteries in series to achieve its The nominal voltage 12.5V, and then through a group of the same cell re-composition of the parallel circuit, the overall battery capacity to 4000MAh, this battery is said to the general 6CELL cell group.

For notebook computer batteries, as well as internal and external power supply are some of the principles of understanding, we will be able to work better in the day-to-day life Presario R3000 battery  used in notebook. Then I talk about in their own laptop batteries for use in some of the experiences and suggestions.

First of all, get a piece of new batteries, a lot of users is in accordance with the practice of business tips in the lithium batteries used in the previous three charging even more than 12 hours. In this debate there are many on-line, but I found that in actual use, in fact, the majority of the notebook battery is not necessary. Why? Merchant said that in order to fully activate the cell’s activity is entirely new wake-up battery. For this reason it sounds very full and credible, but we have not thought about this issue. If, notebook battery manufacturers have not yet been fully activated on the play, so the product can be said that only a semi-finished products. Can not require each user to master the skills to activate the battery, it is impossible in reality. As a result, the battery factory has been a manufacturer of a fully activated. How are charging customers 12-hour battery life in favor of it? Here the author gives a negative answer, the current notebook batteries have improved power management circuits and charging management system, when the battery reached saturation, the control circuit automatically switch to short-circuit, it is only after time in a waste of time Only. How can activate the battery of this activity? In fact, the manufacturer of the battery is activated in the absence of overload protection of the battery will discharge and recharge for a long time. Therefore, charging three times before the 12 hours is not necessary.

At times, a lot of users in the use of batteries in the very confused as to whether or not to wait until the A2 battery  run out completely before charging. In fact, this question should be answered like this, if you can do is certainly a good thing, but the premise is your problem too. Of course, I am talking about here is not referring to the excessive discharge, excessive discharge Practice has proved that the battery is absolutely harmful, it will shorten the battery life. Therefore, when the notebook prompted a time of low power consumption will be able to charge the appropriate time. Some business has repeatedly stated that its lithium battery memory effect did not, this is very irresponsible. So when your battery power when there is more still do not charge for the good, because the memory effect is real.

Thirdly, the need for long-term battery should be how to do, into the proposed 40-50% of the electricity, placed in the shade of the low-temperature, the following parameters will be able to note the problem.

Storage temperature of 40% of the state-of-charge 100% state of charge
0 degrees 98% (after one year) 94% (after one year)
25 degrees 96% (after one year) 80% (after one year)
40 degrees 85% (after one year) 65% (after one year)
60 degrees 75% (after one year) 60% (3 months)

(Percentage of saturation at the time of the initial value of the relative percentage)
Of course, the best month we should come out with a battery, the battery can ensure a good state of preservation, and not let the loss of full electricity and cell damage.

Fourth, in notebook computers for use in “a month after the release should be sufficient full-time” if necessary. Notebook computer lithium-ion batteries used in general management with a chip and charge control chips. One-chip management in a series of registers, there is capacity, temperature, ID, state-of-charge, discharge, such as the number of values. These values are in use will gradually change. Personally, I think, in notebook computers for use in “a month after the full charge should take a” leading role of these amendments is to be improper, the value of the register, making the asus battery charge control and battery with a nominal capacity of the line The actual situation. This is why the work could not be omitted, after all, the high-priced notebook or effemination the aristocracy.

In the final turn on the use of, books in the cell how to make longer. Since you bought a laptop is to use it, the battery is one of consumables, as is bound to use the time to renew and scrapped. What books to allow a longer battery life? Power-saving technology? Sleep? Hard to let hang? Reduce the brightness of the screen so? All these methods seem to be able to increase the so-called extension of the time. But you have never thought that such a meaningful extension of the time it? I do not run any open book process, do not open display, not to hard, I can not reach a longer period of time. This would be absurd, is used to use the notebook, rather than high-sounding setting. I therefore propose that we make good use of the notebook, rather than about how to use the notebook. Perhaps, two years after the notebook market is another world, your books have reached the ranks of the retired. As long as we pay attention to day-to-day use of batteries used to, the normal cells can be used, there is no need to be timid.

1. Under normal circumstances, the new nickel-metal hydride batteries contain only small amounts of electricity, we must first purchase and then charge for use. However, if the laptop battery factory relatively short time, the electricity is enough to recommend the use of first and then charge.
2.’s Purchase of the new nickel-metal hydride batteries generally go through 3-4 times the charge and the use of performance in order to play its best.
3. Although the Ni-MH battery memory effect of the small, we still recommend the use of as much as possible every time after the end charge and is full of one-time, I will not be sufficient for a moment and then charge. However, this “longevity” an important point.
4. Rechargeable battery, charger should pay attention to the surrounding heat and not to put too many chargers around the debris. The battery contacts to avoid oxidation. If the application of oxidation of paper or cloth wipe, do not sandpaper or grinding wheel, or else they will lead to more serious oxidation.
5. Not for a long time, remember that the battery cell from the warehouse out, under dry conditions, the recommendation into the battery box, to avoid short-circuit the battery contacts and oxidation.
6.’s Not a long-term nickel-metal hydride batteries will be stored in a few months later, the battery into the nature of a “dormant” status, significantly reduce presario battery life. If the nickel-metal hydride batteries have been placed for a long time, I suggest you first slow to carry out sufficient charge is appropriate. Here is another key issue involved: Ni-MH battery, the battery is fully discharged and then save, or save live? These two very different point of view, it should be adopted? Many people believe should be the former, but I think a more reasonable to preserve the battery charged. Because: It has been tested, Ni-MH battery to preserve the best condition that charged about 80% of preservation. This is because Ni-MH battery self-discharge of a larger (10% -15% in a month or so), if the battery completely discharge and then preserved for a long time not to use, the battery self-discharge phenomenon will result in excessive discharge of the battery, Will damage the battery. Do not believe it? What do you think of buying a new nickel-metal hydride rechargeable batteries is not all there is electricity, which is the reason. : More compared to rectify the wrong point of view, from the start in the right direction maintenance batteries, or else they will backfire.
7. Have made many friends in the post asked how the Ni-MH conduct discharge? The expert asked about the number of batteries, reached the same conclusion. Remind friends. Do not try to nickel-metal hydride batteries, rechargeable lead-off put the failure to do so against much larger than their own Ni-MH Presario 900 battery  memory effect!
8. Multimeter battery is full of self-test or not. General in charge Ni-MH battery, 1.2V voltage below the normal voltage in full after about 1.4V. We judge this, it is easy to judge the status of the battery.
9. Charger can be broadly divided into fast and slow-filling charge. Slow flow of small charge, usually around 200mA, such as our common charge current is 160mA or so. Charge for a long time to the 1800mAh Ni-MH battery to 16 hours or so. Although time is a bit slow, but will charge the full charge is enough, and do not hurt the battery. Fast flow usually charge more than 400mA, charging significantly reduce a lot of time ,3-4 hours you can get, and everyone’s favorite to win. Many types of fast filling, the prices vary. So often we all have doubts, are filling fast, and why the price is a big gap in it? Good charger in particular are filling fast with a good anti-over-charge protection, such as the period of hot-selling LCD Panasonic BQ-830 smart charger rapid charger in this regard was especially outstanding.
10. Slow injury does not charge the battery charge time is too long, however; fast charge time can be saved, but the batteries have hurt, even if the surface is the best of the best the world can only be a good charger to reduce the extent of damage, but can not be completely avoided . This contradiction can be resolved is to buy a quick charge and a charge slowly. With sufficient speed and sufficient period of time, for example, at 5, 10, Chong Chongdian slow to switch to one or two. This will also return to the performance of battery-top condition.
11. Batteries are generally used Presario R3000 battery , that is, 4 or 6 series, this time to maintain the balance of each cell is very important, otherwise, because of a battery problem affected the entire battery pack. First of all, to ensure that the battery capacity, the best choice of the same brand of the same type of battery at the same time to buy. Then, to keep the internal battery power, said simply, is that the battery power is either full or empty. If there are more cell group composed of a number of batteries, you can try to “select” look. That is specific to capacity, similar to parameters such as voltage battery series into a single set of batteries, due to inadequate conditions, under normal circumstances, let us test finished after the charge voltage and power good voltage on it.
12. To talk about the final charge and discharge.
   The high-grade NI-MH battery charger using a detection-DELTA V battery voltage to determine whether the battery is full. When the battery voltage discharge curve and a little bit similar to the beginning of a more rapid rise, followed by the slow rise until sufficient good, fast start and voltage drop in the rate of decline is not great. Before commonly used nickel-cadmium batteries are also similar, but the decline in the speed and range than the NI-MH are great. The largest number of chargers on the market (that’s less expensive) is often used in value-charge pressure, such as Po-old GP is the 1.4V charge voltage value, that is, into the battery when the 1.4V voltage in the absence of the poor, charging the end of . Such an outcome is often not the battery is full, especially compared with some of the old battery, due to increasing resistance, the real increase in battery on a lower voltage. This charger current and often smaller, often have to charge more than 10 hours. The use-DELTA V automatic cut off of the charger, because it can accurately control the charging time, it can be more reliable to use the current charge.
   Current nickel-metal hydride rechargeable batteries for the damage we did not think much, on the contrary, now that the use of small electrical appliances, and more high-current charge. The first is a matter of time, do not have to speak. Then, Ni-MH asus battery has a characteristic that you charge the greater the current, it can release the greater the current, electrical power is a tiger, not a small current, relatively speaking, therefore, the use of relatively large Current charge is a wise choice, can increase battery _ clean. 5, the general charge current should not exceed 1.5C, C for the battery capacity is 1000MAH batteries, not more than 1.5A. 0.5C can be used to conduct charge. Discharge, under normal circumstances, after the black electrical charge can be taken up, NI-MH little memory effect. But after a period of time, as well as to balance the use of batteries, battery-activated, to control the discharge of the battery voltage termination. NI-MH battery voltage of the termination of 0.9V, the discharge time careful not to over-discharge, on each battery 0.9V when you can stop the discharge. NI-MH battery has not tough nickel-cadmium batteries, the charge had been released and are more sensitive to high temperatures.
   Charge-discharge temperature. In general, do not let the battery temperature higher than 45 degrees. The battery is full, the batteries will be fever, a high current when the temperature should be about 42 degrees and not more than 45 degrees, the A2 battery  internal resistance will increase. After the battery charge a higher temperature, cooling, and so on before use.
  
   Battery for a long time do not have to re-use, the best sufficient to reactivate the battery release several times. The use of normal time to pay attention to maintaining the integrity of packaging paper, there can not be broken in order to avoid a short circuit. Do not tempering the impact of the battery, do not burn.

In the wrong conditions, the use of the wrong battery can cause an explosion and failure. Will be carefully designed to avoid the breakdown of cell and accidents such as explosions, to reduce the harmful electrochemical reaction and the risks associated with failure.

Lithium-ion batteries have a lot better than other rechargeable  PA3107U-1BRS battery characteristics, including high energy density, light weight, long life cycle, the capacity to maintain good properties, to adapt to the ambient temperature range and current ability to be patient, and so on. Lithium-ion battery’s ability to adapt to the environment than any other battery chemistry better, but the characteristics of high-capacity battery pack means that it must be designed to be safer.

Use Survey

The selection of lithium laptop battery is an important step in a comprehensive description of the equipment, “the use of real profiles.” For example, different equipment temperature limit would result in the same cells produce different results of the performance. Overview of the use of battery following a number of parameters, such as an operating voltage range, the current duty cycle, environmental and operating temperature, the cyclical behavior, and run-time charge, charge and discharge cycles, as well as the frequency of the number of times. In the design and development process, the battery manufacturer’s specification does not contain such details. Only by understanding all the parameters, the VGP-BPS5A   battery pack can be seamlessly integrated into portable devices.

The best battery design should include a redundancy protection circuit, that is, in the main circuit failure, the auxiliary circuits can also play a role. In this way, only the battery in the case of a malfunction, that is, all the simultaneous failure of both circuits.

Battery components

In addition to the smart battery pack contains a number of circuit protection and thermal sensors, it also has a high-level intelligence functions. Such batteries usually contain a component Communications, which can charge and discharge the number of measures to carry out, also includes a total fuel cycle work to track each of the remaining  PCGA-BP2T  battery time and the report of the security situation.

Based on the voltage of the main fuel of dollars to rely on periodic measurements of voltage to the battery capacity to understand. This approach has its limitations because it can only estimate the relative capacity and excessive given the information. First-line approach by measuring the total input current to calculate the battery capacity. This method required the co-processor, connected to the negative battery terminal and induction of resistance between the voltage drop to monitor in order to determine the battery charge and discharge activities. Coulomb-or two-line method, the  M8511 battery can be used in the process to assess the absolute capacity. Two-line method is the most common agreement I2C and SMBus.

Once the battery pack assembly has been completed, most of the fuel should include the completion of the “learning cycle” process, so that the batteries can remember which part is empty and which part is over, and then will be able to correctly set the fuel dollars. However, the most advanced fuel cycle into account, even if do not need to learn, but also be able to achieve 99% accuracy, they are often used in critical applications.

The smart battery system is advanced in many handheld devices to choose a major. Their advanced features allow end-users to manage equipment and intelligence to prevent malfunction or shut down.

Protective measurements

Li-ion battery for internal security to rely on the measurement of heat off the isolation, it separated from the anode and the cathode material and the use of a material to ensure that the internal resistance of the  M2000 battery temperature over time can increase the customs point.

In addition, the battery’s certification program is very useful. When the micro-controller with the battery embedded with the main equipment in communication with the processor, the battery will start the accreditation process. This certification will not only protect from improper use of battery failure caused, but also to prevent the use of reverse plagiarism battery system to process patent.

The batteries used in the material must be monitored because of the heavy metal battery pack must be restricted. Europe’s RoHS directive does not apply to batteries for the time being, some of the equipment is currently adopted by the European Battery Directive 91/157/EEC to manage, and its battery will be included for recycling.
