Vehicle-mounted charging and discharging circuit and vehicle

The utility model discloses a vehicle-mounted charging and discharging circuit and a vehicle. The vehicle-mounted charging and discharging circuit comprises a motor coil, a power factor correction circuit, a conversion circuit and a switching circuit, the power factor correction circuit is electrically connected with the motor coil and the conversion circuit respectively; the motor coil, the power factor correction circuit and the power battery form a motor driving circuit; the switching circuit is electrically connected with the power factor correction circuit and the power battery, and when the switching circuit is closed, the power battery supplies power to the power factor correction circuit. When the switching circuit is closed, the power battery supplies power to the power factor correction circuit, so that the potential of the power factor correction circuit can be maintained, an inductive load and a capacitive load can be compatible when the power battery discharges outwards, and the adaptive capacity of discharging is improved.
