The invention relates to a vehicle power battery pulse heating method, system and device, a vehicle and a storage medium, a bus is added between a motor and a power battery through a first relay switch, when a pulse heating condition meets a preset pulse heating condition, a pulse heating parameter is obtained, and a pulse heating action is executed according to the pulse heating parameter. And when the heating action is executed, the second relay switch is controlled to be switched off, and the first relay switch and the third relay switch are controlled to be switched on. The specific control time sequence is that the lower bridge arm of the inverter is sequentially controlled to be closed, the upper bridge arm is disconnected, the lower bridge arm is disconnected, the upper bridge arm is closed, the lower bridge arm is disconnected, the upper bridge arm is closed, the lower bridge arm is closed and the upper bridge arm is disconnected, and the four time sequences are repeated so as to control the power battery, the bus capacitor and the motor to output pulse current to heat the internal resistor. According to the invention, the pulse heating function of the power battery can be realized only by adding one high-voltage bus on an original vehicle framework and combining sequential control on the inverter, so that the cost is reduced.

    本发明涉及车辆动力电池脉冲加热方法、系统、装置、车辆及存储介质,通过在电机与动力电池之间通过第一继电开关增加一条母线,当脉冲加热条件满足预设脉冲加热条件时,获取脉冲加热参数,并根据脉冲加热参数执行脉冲加热动作。在执行加热动作时,控制第二继电开关断开,第一继电开关与第三继电开关闭合。具体控制时序为依次控制逆变器的下桥臂闭合、上桥臂断开,下桥臂断开、上桥臂闭合,下桥臂断开、上桥臂闭合,下桥臂闭合、上桥臂断开,重复上述四个时序,以控制动力电池、母线电容与电机输出脉冲电流对内阻进行加热。本发明在原有的车辆架构上只需要增加一条高压母线,并结合对逆变器的时序控制即可实现动力电池脉冲加热功能,降低了成本。
