| 5. Semi-constant voltage/constant current charging method of the charger |
|
The charger is controlled by micom to have a plot of charging of [output voltage] vs [output current] using a leakage transformer..
Accordingly, in case that a battery with irregular amount of discharge is charged, the charging is completed by automatic determination of the amount of charge corresponding to the amount of discharge. |
