Beschreibung
Zusammenfassung:	There are provided a voltage detection circuit that measures a voltage of an assembled battery 20 in which energy storage devices 100 are connected in series, a current detection resistor that detects a current of the assembled battery 20, and a CPU 33 that calculates an electrical quantity of energization by continuous charge or continuous discharge of the assembled battery 20. The CPU 33 controls input or output of the assembled battery 20 during charge and discharge such that a ΔSOC, which is a value obtained by dividing the electrical quantity of energization by an available capacity of the assembled battery 20, does not exceed an upper limit ΔSOC.
