A bidirectional vehicle-mounted charger disclosed by the present invention, comprises a first alternating current interface, a second alternating current interface, a direct current interface and a switching circuit. When an electric vehicle is in a driving state, the bidirectional vehicle-mounted charger is used for receiving the electric energy of a power battery through the direct current interface and is used for controlling the second discharge port connected with the second alternating current interface to transmit the electric energy of the power battery to an external load through the switching circuit; when the electric vehicle is in a parking state, the bidirectional vehicle-mounted charger is used for receiving the electric energy of the power battery through the direct current interface, and is used for controlling the second discharge port connected with the second alternating current interface and/or the first discharge port connected with the first alternating current interface to transmit the electric energy of the power battery to the external load through the switching circuit. According to the present invention, the technical problem that a bidirectional vehicle-mounted charger cannot provide energy for an external load in the running process of an electric vehicle is solved.
