The invention relates to the technical field of vehicles, and discloses a vehicle-mounted charger, a controller, a vehicle-mounted power system and an electric vehicle. The vehicle-mounted charger can reuse a winding of a compressor three-phase motor to charge a power battery. According to the vehicle-mounted charger, the controller, the vehicle-mounted charging system and the electric vehicle provided by the embodiment of the invention, the compressor can be charged according to the environment temperature of the three-phase motor of the compressor; one or more of the temperature of the three-phase motor of the compressor and the temperature of a refrigerant in the compressor starts the cooling air conditioner to dissipate heat or drives the three-phase motor of the compressor to start the compressor to dissipate heat while charging the power battery; therefore, the temperature of the vehicle-mounted charger and the compressor three-phase motor is prevented from being too high, and the charging efficiency of the power battery is considered.

    本申请涉及车辆技术领域,公开了一种车载充电机、控制器、车载动力系统及电动车辆。其中,车载充电机可以复用压缩机三相电机的绕组对动力电池充电。本申请实施例提供的车载充电机、控制器、车载充电系统及电动车辆可以根据压缩机三相电机的环境温度、压缩机三相电机的温度或压缩机内冷媒的温度中的一种或多种启动冷却空调进行散热或者在对动力电池充的同时驱动压缩机三相电机启动压缩机进行散热,从而防止车载充电机和压缩机三相电机的温度过高且兼顾动力电池的充电效率。
