Abstract
A power storage apparatus includes a plurality of power storage devices, a switch provided on a current-carrying path to the plurality of power storage devices, a voltage detecting unit that detects respective voltages of the power storage devices, and a control unit. The control unit switches a duty ratio of the switch so as to prevent or delay the voltages of the power storage devices from reaching an upper limit voltage during the charge.
