Abstract

A charge/discharge device switches between allowing and disallowing charging/discharging of an electrical storage unit by switching a relay with a drive circuit. The device, specifies at the time of an anomaly that prevents the relay from operating normally, the portion in which the anomaly has occurred. A charge/discharge circuit performs a charge or discharge operation on an electrical storage cell in response to instructions. A drive circuit generates a drive current where a drive instruction is given, and supplies the drive current to a relay. A control unit controls the instructions that are given to the charge/discharge circuit and instruction that is given to the drive circuit. An anomaly specification unit specifies the portion where an anomaly has occurred based on the power source voltage that is input to the drive circuit, output that is provided from the drive circuit to the relay, and the voltage of a charge/discharge path.
