The application provides a heating method of a power battery, a motor control circuit and a vehicle. The motor control circuit comprises a switch module, a three-phase inverter, a three-phase alternating current motor, an energy storage module and a control module. The control module is connected with a power supply module, the switch module, the three-phase inverter, the three-phase alternating current motor, a to-be-heated part and the energy storage module. According to the technical scheme, an N line is led out from a connection point of a three-phase coil in the three-phase alternating current motor and different loops are formed by the three-phase inverter, the power battery, the energy storage module and the three-phase inverter; a heat source is provided through a three-phase coilin the three-phase alternating current motor, the three-phase inverter, the energy storage module and a heating device in the energy storage module. After the heat exchange medium is heated, a to-be-heated device is heated through the cooling loop, the temperature of the to-be-heated device can be increased without using an engine or adding a heating device, the heating efficiency is high, and thetemperature of the to-be-heated device rises quickly.

    本申请提出了一种动力电池的加热方法、电机控制电路及车辆,电机控制电路包括开关模块、三相逆变器、三相交流电机、储能模块以及控制模块,控制模块连接供电模块、开关模块、三相逆变器、三相交流电机、待加热部件以及储能模块,本申请技术方案在三相交流电机中三相线圈的连接点引出N线,进而与动力电池、储能模块以及三相逆变器组成不同的回路,通过三相交流电机内部三相线圈、三相逆变器和储能模块及其内部发热器件来提供热源,加热换热介质后经过冷却回路实现对待加热器件的加热,不需要使用发动机或者增加加热装置就可以实现提升待加热器件的温度,并且加热效率高,待加热器件温度升高快。
