A charge and discharge system capable of being charged and discharged from and to an external device includes a charge and discharge circuit, a switching system and a controller. The charge and discharge circuit converts electric power from an inlet to direct-current power compatible with an electrical storage device and converts direct-current power of the electrical storage device to electric power that is discharged from an outlet. The switching system connects the charge and discharge circuit to the inlet or to the outlet. The controller determines that the switching system has a failure on condition that an alternating-current voltage has been detected at the inlet and an alternating-current voltage has been detected at the outlet, and disable charging and discharging.
