METHOD AND APPARATUS FOR BALANCING DISCHARGING OF EACH BATTERY IN BATTERY GROUP

摘要

A method and an apparatus for balancing the discharging of each battery in a battery group (1). During the discharging of the battery group (1), certain batteries with low voltage are charged to decrease their discharging quantity. Thereby, the discharging time of the whole battery group (1) is prolonged. Furthermore, all of the batteries almost are in the same status when the discharging is finished, and the battery homogeneity is improved.
