Abstract
Official abstract text for this publication.
The present invention is a control system for an assembled battery that controls an assembled battery comprising a plurality of cells, including: a bypass circuit connected in parallel to each cell of the cells, and comprising a switching element and a resistor connected in series; and a control circuit that controls a bypass current flowing in the bypass circuit by opening and closing the switching element, in order to discharge the cell; wherein the bypass circuit is set so that a current of a same magnitude as a self-discharge current in a predetermined overcharged states of the cell flow in the bypass circuit.
