Abstract

A power storage apparatus includes a storage battery chargeable and dischargeable, a voltage stepping-up/down circuit that performs a voltage stepping-up operation of stepping up by PWM control a voltage supplied from the storage battery and outputting a stepped-up voltage to a high-voltage DC bus line, and a voltage stepping-down operation of stepping down by PWM control a voltage supplied from the high-voltage DC bus line and supplying a stepped-down voltage to the storage battery. Moreover, a detection device is provided that outputs a detection signal indicating a full-charged state of the storage battery, and a controller keeps a high-side switch in the voltage stepping-up/down circuit in an off state in response to input of the detection signal.
