Abstract

A power accumulation system includes a power accumulation device (10), a relay device provided in a pair of power lines disposed between the power accumulation device (10) and a power conversion device that exchanges power with the power accumulation device (10), a capacitor provided between the pair of power lines between the relay device and the power conversion device and an electronic control device (70) that controls the relay device. The electronic control device (70) is configured to execute a predetermined foreign matter removal process when it is not possible to bring one of a first relay and a second relay from a power blocking state to a conductive state.
