The invention relates to a battery charging and discharging method, a battery charging and discharging device, a storage medium and a battery charging and discharging system. The battery charging and discharging method comprises the following steps: acquiring a current SOC state and a battery temperature when a battery is charged and discharged; according to the current SOC state of the battery and the battery temperature, whether the battery meets the charging and discharging conditions of pulse speed heating charging and discharging or not is determined; if the battery meets the charging and discharging conditions of pulse speed heating charging and discharging, the battery type and the charging and discharging mode of the battery are obtained; on the basis of the current SOC state of the battery, the battery temperature, the battery type of the battery and the charging and discharging mode of the battery, the charging and discharging current for pulse rapid heating charging and discharging of the battery is determined, pulse rapid heating charging and discharging of the battery are carried out on the basis of the charging and discharging current, and occurrence of overlarge pulse rapid heating charging and discharging current can be restrained through many condition restrictions. Therefore, the occurrence probability of overlarge pulse current can be reduced.

    本公开是关于一种电池充放电方法、电池充放电装置、存储介质及电池充放电系统。该电池充放电方法,包括获取电池进行充放电时的当前SOC状态及电池温度;根据电池的当前SOC状态及电池温度,确定电池是否满足脉冲速加热充放电的充放电条件;若电池满足进行脉冲速加热充放电的充放电条件,则获取电池的电池类型及电池的充放电方式;基于电池的当前SOC状态、电池温度、电池的电池类型及电池的充放电方式,确定对电池进行脉冲速加热充放电的充放电电流,以基于充放电电流对电池进行脉冲速加热充放电,可通过诸多条件限制来约束过大的脉冲速加热充放电流出现,从而有利于降低过大的脉冲电流的出现概率。
