The invention provides a thermal management control method of a pure electric vehicle, a controller and a vehicle. The method comprises the steps that a target value of the water temperature of a motor is determined according to a battery heating request and/or an air conditioner heating request; if it is determined that a generator locked-rotor heating mode needs to be started according to the target value of the water temperature of the motor, the first current value of the water temperature of the motor, the suction pressure of a compressor and the vehicle state, the target operation power of the motor is determined according to the target value of the water temperature of the motor and the first current value of the water temperature of the motor; thus, the locked-rotor heating mode of the generator is triggered according to the heating requirement of the battery and the heating requirement in the passenger compartment, appropriate heating capacity can be provided for the vehicle, the heating requirement of the passenger compartment and the battery can be met under the condition that a PTC heating component is removed, and the vehicle cost can be reduced.

    本发明提供了一种纯电动汽车的热管理控制方法、控制器及车辆,方法包括:根据电池制热请求和/或空调制热请求确定电机水温的目标值;若根据所述电机水温的目标值、所述电机水温的第一当前值、压缩机吸气压力以及车辆状态确定需要触发电机堵转制热模式开启,则根据所述电机水温的目标值及所述电机水温的第一当前值确定电机的目标运行功率;如此,根据电池制热需求和乘舱内的制热需求触发电机堵转制热模式,可以为车辆提供合适的制热量,既可以在去除PTC加热部件的情况下满足乘舱和电池的制热需求,也可以降低车辆成本。
