Method of Lithium battery charging

Li-ion batterey , Panasonic CGR-S003charging methods are: pre-charging, constant current charging, constant voltage charging, temperature monitoring.

1. Pre-Charge: If the single JVC bn-vf823 cell voltage is lower than the set voltage value, charge go into the pre-charge cycle in the first time, in general single cell configuration is less than 3.0V, as long asit is less than the voltage ,that is to enter the pre-charging time.


2. Constant-current charge: As long as single Sony NP-FC11cell voltage is higher than the set voltage value, the charge cycle can go into the constant current charging, charge the battery with the greatest current. in general setting of this single cell voltage is 3.0-4.2V.


3. Constant Charge: When the battery forOlympus li-12b is in the process of charging, the battery voltage reaches the set value, the charge cycle can go into the constant voltage charging. In the constant voltage charging, the voltage is constant and current gradually reduced from the maximum, when the current is reduced to set value, the battery, Casio NP-100 is full. a general set current is 50mA.


4. Temperature control: we accurately determine the temperature of the Canon NB-2L battery in the whole process of charging by an external thermistor toon the battery to achieve real-time monitoring, and it can avoid the battery temperature is too high or too low, resulting in damage to the battery for Nikon EN-EL4 or the occurrence of the hazard.

.li-ion battery nominal voltage is generally: 3.6V, 3.7V;li-ion Olympus li-10b battery charging voltage is generally: 4.23V-4.26V.
