The invention discloses a power battery pulse heating method and device, a terminal and a storage medium, and belongs to the technical field of power battery heating. When heating request data is received, heating related parameters in the heating request data are obtained; the heating completion time is determined according to heating preset related parameters, and the pulse heating frequency, the charging current amplitude and the discharging current amplitude are determined according to the heating completion time; and heating the power battery according to the pulse heating frequency, the charging current amplitude and the discharging current amplitude, obtaining real-time heating data of the power battery, and judging whether heating needs to be continued or not according to the real-time heating data. According to the method, when the battery temperature is increased through pulse self-heating of the electric vehicle, intervention control is conducted in advance, the pulse self-heating rate is the optimal heating rate, and meanwhile the use convenience and user experience of the electric vehicle are met.

    本发明公开了一种动力电池脉冲加热方法、装置、终端及存储介质,属于动力电池加热技术领域,当接收到加热请求数据时,获取所述加热请求数据中的加热相关参数;根据加热预设相关参数确定加热完成时间并根据所述加热完成时间确定脉冲加热频率、充电电流幅值和放电电流幅值;按照所述脉冲加热频率、充电电流幅值和放电电流幅值对动力电池进行加热,获取动力电池加热实时数据并根据其判断是否需要继续加热。本发明在电动汽车脉冲自加热对电池温度进行提升时进行提前干预控制,在使脉冲自加热速率在最佳加热速率同时满足电动汽车使用的便利性及用户感受。
