The invention discloses a battery pack charging system which comprises a battery pack and a charging cabinet. A nitrogen replacement device is arranged in the charging cabinet, the charging cabinet provides charging and nitrogen charging for the battery pack, and the battery pack charging system is characterized in that an inflation protection device is arranged between the nitrogen replacement device and the battery pack and the inflation protection device is used for automatically adjusting the inflation flow of nitrogen. The invention further discloses a charging method of the battery pack charging system. The battery pack charging system has the beneficial effects that the form of the existing battery pack of the electric bicycle is changed, and feasible technical support is provided for 'shared battery replacement' of the existing battery pack of the electric bicycle; then, on the basis of improving the battery pack of the electric bicycle, a battery cabinet capable of charging and filling nitrogen into the battery pack at the same time is provided for the battery pack, so that thermal runaway of the battery is prevented and controlled from the source; and moreover, a new method is provided for filling nitrogen into the battery pack, and the defect that double electromagnetic valves and an oxygen concentration sensor are used in the prior art is overcome.

    本发明公开了一种电池包充电系统,包括电池包和充电柜,所述充电柜内置有氮气置换装置,所述充电柜为所述电池包提供充电和充氮气,其特征在于:在所述氮气置换装置与电池包之间设有充气保护装置,所述充气保护装置用于自动调节氮气的充气流量。还公开了一种电池包充电系统的充电方法。有益效果:本发明一改现有的电动自行车的电池包形式,为现有电动自行车电池包的“共享换电”提供可行性技术支持;其次,在改进电动自行车电池包的基础上,为电池包提供了一种可同时充电和向电池包内部充氮气的电池柜,从根源上防控了电池热失控;再者,为向电池包内部充氮气提供一种新的方法,避免了现有技术中使用双电磁阀以及氧气浓度传感器的弊端。
