Abstract
In a battery charger for charging a plurality of battery cells connected in series with each other with a constant current in a batch manner, the present invention is intended to suppress the generation of heat in cell shunt circuit sections which are provided as overheat protective measures for the individual cells. Surplus energy, which is generated in the cell shunt circuit sections by the product of a cell voltage and a shunt current and which becomes a heat generating source, is regenerated to a charger side via a flyback transformer provided in each of the cell shunt circuit sections, thereby suppressing heat generation.
