Abstract
A battery charging apparatus includes a charging module and a control module. The control module obtains a DIR (dynamic internal resistance) of a battery cell group based on a voltage and a current of the battery cell group, and generates a control signal based on the voltage and the DIR of the battery cell group. The charging module alternates between outputting and not outputting a charge current/voltage to charge the battery cell group based on the control signal.
