The invention provides a vehicle-mounted charger and a working method. The vehicle-mounted charger comprises a motor driving device, a charging accessory, a motor, a switching circuit and a terminal,the motor driving device is connected with the motor through the switching circuit; the motor driving device is connected with the terminal; when the switching circuit is closed and the charging accessory is not connected with the terminal, the motor driving device drives the motor through the switching circuit; and when the switching circuit is disconnected and the charging accessory is connectedwith the terminal, the power grid charges the vehicle through the charging accessory and the motor driving device. According to the invention, the existing motor driving device of the new energy automobile is reused; and meanwhile, the form of the charging accessories is adopted, the charging accessories are installed on the new energy automobile in the charging state, the charging accessories are unloaded from the new energy automobile when charging is not conducted, the number of electrical elements of the new energy automobile is reduced, and the production cost, size and weight of the newenergy automobile are reduced.

    本发明提供了一种车载充电器和工作方法,该车载充电器包括:电机驱动装置,充电配件,电机,开关电路,端子;电机驱动装置经开关电路连接电机;电机驱动装置与端子连接;开关电路闭合,且充电配件未连接端子时,电机驱动装置经开关电路驱动电机;开关电路断开,且充电配件连接端子时,电网经充电配件和电机驱动装置,为车辆充电。本发明通过复用新能源汽车已有的电机驱动装置,同时采用了充电配件的形式,在充电状态时将充电配件安装在新能源汽车上,不充电时将充电配件从新能源汽车上卸载,减少了新能源汽车的电气元件数量,降低了新能源汽车的生产成本、体积和重量。
