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.
