The invention discloses a vehicle-mounted charger for an electric vehicle, and belongs to the field of electric vehicle chargers. The invention aims at the problems that: an existing vehicle-mounted charger is single in working mode and cannot meet the requirements of charging, motor driving and diversified charging of an electric vehicle. An alternating current input circuit is connected with a primary side circuit, the primary side circuit is connected with a primary side coil of a transformer, a secondary side coil of the transformer is connected with a high-voltage battery pack through a secondary side circuit, a first mode switch K1 is arranged between the alternating current input circuit and the primary side circuit, and the motor is connected between the first mode switch K1 and the primary side circuit through a second mode switch K2. According to the invention, two working modes of charging and driving can be realized, and the requirement of diversity of the charging modes of the electric vehicle is met.

    本发明公开了一种电动汽车车载充电机,属于电动汽车充电机领域。本发明针对现有的车载充电机工作模式单一,不能满足电动汽车的充电、电机驱动以及多样化充电的需求的问题。本发明的交流输入电路连接原边侧电路,原边侧电路连接变压器的原边线圈,变压器的副边线圈通过副边侧电路连接高压电池组,交流输入电路与原边侧电路之间设有第一模式开关K1,电机通过第二模式开关K2连接第一模式开关K1与原边侧电路之间。本发明具有能够实现充电和驱动两种工作模式,满足电动汽车充电模式多样性的需求。
