A unit selection unit (120) selects, from among a plurality of electrical storage units (110), a predetermined number of the electrical storage units, and connects the selected electrical storage units to input/output terminals (140). A control unit (130) controls the unit selection unit (120). More specifically, during continuous discharge from the input/output terminals (140), the control unit (130) switches between the electrical storage units (110) selected by the unit selection unit (120), and repeatedly selects the same electrical storage units (110) after a time period has elapsed. |
