The invention belongs to the technical field of vehicle heat management, and particularly relates to a battery self-heating system and a vehicle. The battery self-heating system comprises a three-phase alternating current motor, a heating control contactor, a motor controller and a battery pack, the battery pack comprises at least two battery packs which are connected in series, and the motor controller comprises a three-phase inverter; the positive electrode of the battery pack is connected with the first confluence end of the three-phase inverter, and the negative electrode of the battery pack is connected with the second confluence end of the three-phase inverter; the three-phase lines of the three-phase AC motor are respectively connected with the three-phase bridge arms of the three-phase inverter. A neutral point of the three-phase alternating current motor is connected to a series connection point between any two adjacent battery packs through a heating control contactor. According to the battery self-heating system, mutual charging and mutual discharging can be achieved only through one heating control contactor so as to conduct alternating current heating on the battery pack, the circuit modification of the battery self-heating system is little and simple, and the modification cost is greatly saved.

    本发明属于车辆热管理技术领域,特别是涉及一种电池自加热系统及车辆。该电池自加热系统,包括三相交流电机、加热控制接触器、电机控制器以及电池包,电池包包括相互串联的至少两个电池组,电机控制器包括三相逆变器;电池包的正极连接三相逆变器的第一汇流端,电池包的负极连接三相逆变器的第二汇流端;三相交流电机的三相线分别连接三相逆变器的三相桥臂;三相交流电机的中性点通过加热控制接触器连接在任意相邻两个电池组之间的串联点上。本发明中,该电池自加热系统仅需一个加热控制接触器既能实现互充互放以对电池包进行交流加热的功能,且该电池自加热系统对电路的改造少且简单,大大节约了改动成本。
