Abstract
An electric power conversion device for a power storage device includes a first control device, an electric power conversion circuit that is configured to output electric power to the power storage device, a drive circuit that generates a drive signal for the electric power conversion circuit by using power supply electric power, a shutoff circuit that shuts off supply of the power supply electric power to the drive circuit, and a detection circuit. The detection circuit is configured to output a shutoff signal to the first control device based on a fact that the shutoff by the shutoff circuit is completed. The shutoff signal indicates that the supply of the power supply electric power to the drive circuit is shut off.
