Abstract

A battery pack is formed by serially connecting a plurality of cells, that are individually constructed as rechargeable batteries. Charging and discharging of this battery pack are controlled such that, the proportion of discharge current with respect to the charge current equals to a value obtained by multiplying the charge current by a charging efficiency corresponding to a target SOC value.
