Abstract
The charge and discharge are performed by a proper electric power corresponding to the service environment of a battery and the state of the battery. When the temperature of the battery is not more than a specified temperature, or not less than another specified temperature, the upper limit value Pin-s of the charging electric power and the upper limit value Pout-s of the discharging electric power are determined so as to be smaller than those at a normal temperature. The temperature of the battery is detected, and the charging electric power and the discharging electric power are determined so that they may be not more than the upper limit values Pin-s, Pout-s of the charging and the discharging electric power at this temperature, and the charge control of the battery is performed.
