Battery low-temperature pulse charging method and device

According to the battery low-temperature pulse charging method and device provided by the invention, in the charging process of the battery pack, the battery pack is subjected to instant pulse discharging with the reverse duration, then the battery pack is charged, the whole process is a bidirectional pulse charging process, and the charging method has an obvious effect of inhibiting the lithium precipitation phenomenon when being used for charging, so that the charging efficiency is improved. According to the invention, the polarization phenomenon in the charging process of the battery can be relieved, the charging acceptance of the battery is improved, additional equipment for heating the battery pack is not needed, and the waste of resources is reduced. 本发明提供一种电池低温脉冲充电方法和装置，在电池包充电过程中，对电池包进行反向的时长的瞬间脉冲放电，然后再对电池包进行充电，其整个流程为一个双向脉冲充电流程，采用该充电方法进行充电对析锂现象的抑制有明显的效果，能够缓解电池充电过程中的极化现象，提高电池的充电接受能力，无需增加额外的设备对电池包进行加热，减少了资源的浪费。
