This application provides a charging apparatus and a new energy vehicle. The charging apparatus is applied to the new energy vehicle. The new energy vehicle includes a first battery and a second battery. The first battery provides driving power for the new energy vehicle, and the second battery supplies power to a vehicle-mounted load device. The apparatus includes a charging unit and a general-purpose unit. The charging unit includes a DC-DC circuit and a BMS. The general-purpose unit includes a control module, a communication module, and an auxiliary power supply module. The auxiliary power supply module supplies power to the charging unit and the control module. The control module is configured to control the charging unit to provide electric energy of the first battery to the second battery. The control module is configured to: control the charging unit to connect the second battery to or disconnect the second battery from the first battery and the vehicle-mounted load device, and adjust charging and discharging power provided by the second battery for the vehicle-mounted load device. According to the apparatus provided in this application, a volume and a weight of the charging apparatus can be reduced, a service life of a battery can be prolonged, an in-vehicle communication and control architecture can be simplified, a vehicle layout space can be saved, and wire harness costs can be reduced.
