The invention relates to the field of power batteries, and provides a control method for battery pack heating, a motor controller and a battery pack heating system. The control method is applied to a motor controller of a vehicle and comprises the steps of receiving a first instruction sent by a whole vehicle controller of the vehicle in response to a fact that the temperature value of a battery pack is smaller than a preset temperature threshold value, wherein the first instruction is used for indicating the motor controller to enter a preset current mode; and entering a current mode in response to the first instruction, and enabling the motor to output a current to the battery pack by applying a current vector to the motor in the current mode so as to realize heating of the battery pack. According to the embodiment of the invention, the motor controller enables the motor current to heat the battery pack, other heating devices do not need to be added, the cost is reduced, and the heating efficiency is high.
本发明涉及动力电池领域,提供一种用于电池包加热的控制方法、电机控制器及电池包加热系统。本发明所述的控制方法应用于车辆的电机控制器,且包括:接收车辆的整车控制器响应于电池包温度值小于预设温度阈值而发送的第一指令,其中所述第一指令用于指示所述电机控制器进入预设的电流模式;以及响应于所述第一指令进入所述电流模式,在该电流模式下通过向所述电机施加电流矢量来控制所述电机向所述电池包输出电流,以实现电池包加热。本发明实施例通过电机控制器控制电机电流以实现电池包加热,无需增加其他的加热器件,降低了成本,且加热效率高。
