Abstract
The present invention discloses a battery pack charging system, comprising battery packs and a charging cabinet, a nitrogen replacement device is arranged inside the charging cabinet, the charging cabinet provides charging and nitrogen filling for the battery packs, wherein: there is a gas-filling protective device arranged between the nitrogen replacement device and the battery packs, and the gas-filling protective device is used to regulate the gas-filling flow of nitrogen automatically. Also disclosed is a charging method of the battery pack charging system. Beneficial effects: Different from the existing battery pack forms of electric bicycles, the present invention provides a feasible technical support for the 'shared power changing' of the existing electric bicycle battery packs; Secondly, on the basis of improving the battery pack of electric bicycles, a battery cupboard capable of charging and filling nitrogen into the battery pack at the same time is provided for the battery pack, thus fundamentally preventing the thermal runaway of the battery; Moreover, a new method is provided for filling nitrogen into the battery pack, avoiding the defects of using double solenoid valves and oxygen concentration sensors in the existing technologies.
