The invention relates to a battery heating method, device and equipment, a storage medium, a system and a vehicle, and relates to the technical field of electric vehicles. The method is applied to a battery heating system. The battery heating system comprises a power battery, a motor controller power module, a three-phase motor, an inductance module and cooling liquid. Cooling liquid sequentially flows through the motor controller power module, the three-phase motor, the inductance module and the power battery. The method comprises the following steps: receiving a heating request message sent by a battery controller; and in response to the heating request message, controlling any one of the first power switch, the second power switch and the third power switch to be switched on in the current period, and controlling the other two power switches to be switched off. Thus, no electromagnetic force is generated in the stator winding of the three-phase motor, and torque output can be effectively avoided. Meanwhile, the motor controller power module, the three-phase motor and the inductance module can heat the power battery in a cooling liquid heating mode.
本申请涉及一种电池加热方法、装置、设备、存储介质、系统及车辆,涉及电动汽车技术领域。该方法应用于电池加热系统,电池加热系统包括:动力电池、电机控制器功率模块、三相电机、电感模块和冷却液;冷却液依次流经电机控制器功率模块、三相电机、电感模块以及动力电池。该方法包括:接收电池控制器发送的加热请求消息;响应于加热请求消息,在当前周期内控制第一功率开关、第二功率开关、第三功率开关中的任意一个功率开关导通,并控制其他两个功率开关断开。这样,不会在三相电机的定子绕组中产生电磁力,可以有效避免扭矩输出。同时,电机控制器功率模块、三相电机、电感模块可以通过加热冷却液的方式使得动力电池升温。
