Abstract
The present invention comprises a voltage detection circuit for measuring the voltage of an assembled batteryin which power storage elementsare serially connected, a current detection resistor for detecting the current in the assembled battery, and a CPUfor calculating, inter alia, the amount of energization electricity from continuous charging or continuous discharging of the assembled battery. The CPUcontrols input/output for when the assembled batteryis charged/discharged so that ΔSOC, which is the value obtained by dividing the amount of energization electricity by the actual capacity of the assembled battery, does not exceed an upper limit ΔSOC.
