A vehicle-mounted device (700A, 700B) and a vehicle charging apparatus (500A, 500B) including the same, the vehicle-mounted device including an inverter (704A, 702B) including a first inductance coil (7042A, 7022B) and connected to a drive motor of a vehicle, the first inductance coil serving as a secondary of a transformer in a charging mode of the vehicle; a bidirectional DC/DC converter (706A, 704B) that is connected to the inverter; and a battery pack (708A, 706B) that is connected to the bidirectional DC/DC converter. The vehicle charging equipment comprises a non-vehicle-mounted charger (600A, 600B) and the vehicle-mounted device, the non-vehicle-mounted charger or the vehicle-mounted device comprises a conversion circuit (702A, 604B), and the conversion circuit comprises a DC/AC converter (7022A, 6042B) and a second inductance coil (7024A, 6044B). The second inductance coil is used as a primary, the first inductance coil is used as a secondary, and the first inductance coil and the second inductance coil jointly form a transformer. According to the vehicle-mounted device and the vehicle charging equipment, the structure is simplified, the cost is reduced, and the size of the vehicle-mounted device is reduced.

    一种车载装置(700A,700B)及包括其的车用充电设备(500A,500B),该车载装置包括逆变器(704A,702B),其包括第一电感线圈(7042A,7022B)且与车辆的驱动电机相连,其中,在所述车辆的充电模式下,该第一电感线圈用作为一变压器的次级;双向DC/DC变换器(706A,704B),其与该逆变器相连;以及电池组(708A,706B),其与该双向DC/DC变换器相连。该车用充电设备包括非车载充电器(600A,600B)及该车载装置,该非车载充电器或该车载装置包括变换电路(702A,604B),该变换电路包括DC/AC变换器(7022A,6042B)和第二电感线圈(7024A,6044B)。该第二电感线圈被用作为初级,该第一电感线圈被用作为次级,两者共同组成变压器。本发明的车载装置及车用充电设备简化了结构、降低了成本且减小了车载装置的体积。
