Abstract
The method of charging a battery array performs constant current, constant voltage charging of a battery array while detecting the voltage of each battery. The battery array is a plurality of series connected batteries. The charge method detects the voltage of each battery cell at a prescribed sampling rate. When the voltage of any battery cell exceeds a preset maximum specified voltage, charging power is reduced for constant current, constant voltage charging of the battery array.
