ABSTRACT:
For a charge to a serial connection or a series-parallel connection of secondary cells or modules thereof, a charger controllable for a reduction of charge current with a response time and bypass circuits each respectively connected in parallel to a corresponding one of the cells or modules are controlled such that a voltage of the corresponding cell or the corresponding module is predicted of a time point after a lapse of the response time, and the reduction of charge current is started when the predicted voltage has reached an upper limit voltage set therefor.
