A variety of battery charging method

Lead-acid battery charging method

 

1. Lead-acid battery charging method and the method of Li-ion battery, as it is: pre-loading, load current constant voltage constant monitoring of temperature, floating charge (maintenance)

2. Pre-Charge: If the single cell voltages lower than the set value of voltage, load in the pre-charge cycle, the first time, the general configuration of single-cell is less than 1.65 V, both below the voltage entered on the pre-loading time.

3. Current load constant: as a single-cell voltage exceeds the set value of voltage, the charge cycle in the constant load current with the most current to recharge theVGP-BPS9A/B VGP-BPS9/S  battery. The general tension setting of this unicellular 1.65-2.47V

4. Constant Charge: When the battery in the process of charging, the battery voltage reaches the set value, the charge cycle, in constant tension. In the constant voltage, constant voltage and current gradually reduced from the maximum when the current is reduced to set value, the battery is full. Generally set at 200 mA, 400 mA current.

5. Temperature control: In the whole process of charging an external thermistor to accurately determine the temperature of the battery on the battery to achieve real time, to avoid the battery temperature is too high or too low, causing the battery damage or danger.

6. Floating Chong Chongdian (maintenance): Lead-acid battery is fully charged, the battery charge cycle in floating, floating Chong Chongdian cycle is to keep the battery as no self-discharge to keep the battery in the completeness. Chong Chongdian state floating cells are not afraid of a long charge to ensure that there is no worse off after the F4809A F4812A battery power pack.

7. The three-step method of loading on the market as follows: pre-load, load at constant current, constant voltage.

8. Lead acid are generally rated voltage: 6V, 12V, 24V, 36V, 48V, grid cell for each single nominal voltage of 2.0 V.

9. Lead-acid battery charging voltage equal to: 7.4V, 14.8V, 29.6V, 44.4V, 59.2V.

10. Lead acid battery voltage float match: 6.9V, 13.8V, 27.6V, 41.1V, 55.2V.

 

Lithium battery charging method

 

1. Li ion as long as the charging method is as follows: pre-load, load at constant current, constant voltage, the temperature monitoring.

2. Pre-Charge: If the single cell voltage lower than the set value of voltage, load in the pre-charge cycle, the first time, the general configuration of single-cell is less than 3.0V, as long as less than tension between the pre-charge time.

3. Current load constant: as a single-cell voltage exceeds the set value of voltage, the charge cycle in the constant load current with the most current to recharge the PA3383U-1BRS PA3395U-1BRS battery. The general framework of the tension of a single cell of 3.0-4.2V.

4. Constant Charge: When the battery in the process of charging, the battery voltage reaches the set value, the charge cycle, in constant tension. In the constant voltage, constant voltage and current gradually reduced from the maximum when the current is reduced to set value, the battery is full. General 50mA current range.

5. Temperature control: In the whole process of charging an external thermistor to accurately determine the temperature of the battery on the battery to track in real time to prevent the battery temperature is too high or too low causing damage to the battery or the occurrence of risk.

6.li monomer ion is generally rated voltage: 3.6V, 3.7V

Monomer 7.li-ion charging voltage is typically: 4.23V-4.26V

 

Ni-Cd, Ni-MH rechargeable and processes of pricing methods:

 

1. Charging process: pre-charge, fast charge, top-up maintenance charge.

2. Pre-load: just start charging a low BATCL50L LCBTP03003 rate of charge, to meet certain conditions, pricing, and then transferred to load faster.

3. Quick charge: is divided into constant current load and the load pulse:

A. Constant-load current is a constant current to charge the battery;

B. Load pulse was first used a pulse of current to recharge the battery, then let the battery discharge and so on.

4. Surcharge: A quick method of charge termination, after the cessation of fast charging, the battery power is not sufficient to ensure the battery charging to 100% of electricity, but also join the increase the rates charged are usually no more than 0.3c, the additional charge process, the temperature will continue to increase when the temperature exceeds the limit, the net of the shipper in the state.

5. Charge compensation: Also known as maintenance costs, according to the battery self-discharge characteristics of the loading rate of maintenance are generally low. While connected to the battery charger and the charger connected to power in maintaining the state of charge, the shipper a charge rate will be added to the power of the 6Y270 75UYF battery, it will give the battery is fully charged state of the total. Load current is less than 0.1C, we called the trickle charge.

The proper use of laptop can extend laptop battery life

Laptop battery life is indeed a headache issue to us, although we can not make any changes to Laptop battery, but we can improve the utility by changing the habits of notebook using, so that battery life is lengthened. These more than 10 tips below is the practical method prepared for notebook users to extend battery life.

 

1. Defrag regularly

 

Defragging your hard drive that allows to work faster, make the hard disk defrag on a regular basis to maintain effective state, of course, defrag when using an external power supply. The disk response speed become quicker and working time become shorter, it will certainly reduce the power consumption to extend laptop battery life.

 

2. To reduce the screen brightness

 

Most of the laptop screen brightness can be adjusted, there are some even can reduce the CPU’s operating frequency. When using the Dell Latitude D610 battery, reduce these parameters can be more effective to extend battery life.

 

3. Turn off background programs

 

There are some programs running in the background, although not directly see these programs running, but all consume CPU processing power, of course, consume battery power. The best way is to turn off all unnecessary background processes in order to prolong battery life.

 

4. Reduce the peripheral equipment

 

USB devices (including your mouse), Wi-Fi wireless connections are able to consume hp F4809A battery power, when the equipment is not in use, the best way is to pull down or masked. There is some equipment, such as the iPod will begin to charge when connecting with the computer, be careful not to do it when using the battery-powered laptop.

 

5. Adding more memory

 

More memory means that notebooks do not be so dependent on virtual memory. Virtual memory is built on the hard drive, obviously access memory power consumption is lower, so more read the memory rather than the hard drive, this can reduce power consumption. However, adding memory also can trigger the issue of energy consumption, so the computer often use virtual memory, the most the time to consider adding memory.

 

6. Do not use drive too much

 

Although the hard drive power consumption relatively larger, but in fact the energy consumption of drive is more in the eyes. Even when not in use, CD-ROM is still rotate, consume energy. If you can find a suitable virtual CD-ROM files, through a virtual drive to read, obviously much less power consumption.

 

7. To keep the interface clean

 

We proposed here, every few months to clean up laptop battery metal interface, you can wipe by a cloth soiled with alcohol. This can ensure that the toshiba PA3399U-1BAS battery inside the battery can be more effectively transmitted to the various components to consume.

 

8. Take good care of the battery

 

Take good care of the battery is not to shelved, but regular check it out. Do not let the battery fully charged do nothing for a long, long time. Once charged the battery power, you should at least fully used once every two or three weeks. Of course, do not let your battery completely consume the electricity, it is the way to deal with the old battery memory effect.

 

9. Hibernate instead of standby

 

Although the stand-by allows users to immediately return to work status, but this feature is clearly not better than Hibernate to save power. Hibernate also be able to save your current work status, and almost a complete cessation of electricity consumption for laptops.

 

10. Reduce the operating temperature

Notebook temperature lowered to a more efficient operation. For the notebook used relatively long time, the internal would be a considerable degree of dust accumulation, which can raise laptop internal working temperature. Regular cleaning the inside of notebook is also important for extending apple A1061 battery life.

 

11. Optimize the Power Options

 

In the Windows control panel, there is a power option button, through the button, you can set up and optimize your laptop’s power options. There are some notebooks come with more powerful management software, it would be more convenient for users to use.

 

 

12. Non-multi-tasking

 

When using the battery, it is best to run only one task, rather than dealing with reports, send and receive messages in the background, while playing music, and so on. multi-tasking can only give you a faster notebook TravelMate 290 battery consumption, but also power off when some work haven’t done.

 

13. Less to run large programs

 

To extend battery life, it is best to run a small amount of heavy task large program. Send and receive mail, handling of electronic documents, are clearly smaller power consumption than play the game and DVD discs.

 

14. Buy a new laptop

 

The nootbook accompany us for several years is certainly not willing to throw away, but the harsh fact is: they are already old, already can not keep up the efficiency. The latest notebook, upgrade a lot on energy consumption, if you want longer VGP-BPS2B battery life, it may be picking up new love and throwing old love.

 

15. To prevent memory effect

 

If your laptop has used for a long time, it must be pay attention to prevent “memory effect” generation. Every couple of weeks let your battery fully charge and discharge, of course, if you are using lithium-ion batteries, then there is no need to do this.

 

16. Turn off auto-save

 

Microsoft Word, Excel and other programs have auto-save feature, in most cases this is an intimate setting, but when using the IBM ThinkPad R32 battery, which undoubtedly added to the hard disk work. Turn off this feature requires you to remember from time to time to save the document, prevent the results of hard work go down the drain.

 

17. Reduce the graphics application

 

For example, we can change the graphics resolution, close some aesthetic effects, graphics card is a remarkable place, because of nowadays the graphics card consumption has been almost, and some even higher than the hard drive power consumption.
