Original Abstract Submitted
A charge discharge device includes: a bidirectional charger for converting a power from an external power supply into DC power, and converting DC power of the battery into AC power; and a controller for controlling the bidirectional charger. Further, the bidirectional charger includes an AC/DC converter, a DC/DC converter, an output terminal electrically connected to a power line, and a switch provided between the power line and the output terminal, the output terminal is electrically connected to an electrically heated catalyst, and in a case power of the battery is supplied to the electric heating catalyst and the external device at a same time, when a required voltage of the electric heating catalyst is lower than the output voltage corresponding to a power supply possible range of the external device, the controller intermittently operates the switch.
