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.

A power storage apparatus, comprising:
- 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;
- a control unit, wherein 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 charge;
- an external terminal to which a charger is connected, the switch being disposed between the external terminal and the power storage devices;
- and
- a case in which the power storage devices and the switch are contained, the case being provided with the external terminal.
