Description

Technical Field

[0001] The utility model relates to an electricity storage and exchange system, mainly to the field of electricity exchange. Background Art

[0002] As a way to supplement energy for electric vehicles, battery swapping stations can greatly improve the efficiency of battery swapping for vehicles. The main working mode of the current mainstream battery swapping stations, such as the battery swapping station disclosed in the patent document with publication number CN117207830A, is still charging and battery swapping in one, that is, the battery swapping station charges the battery while the liquid car replaces the battery. In other words, its charging and battery swapping are in the same space. In fact, charging and battery swapping belong to two different work contents. Charging has lower space requirements, but higher safety such as temperature and fire protection. Battery swapping has higher space requirements, that is, it is necessary to provide a larger space for the battery swapping car. If multiple battery swapping stations are required, the area will be directly doubled, but the temperature and fire protection will be relatively lower. Setting the two in the same space will lead to the superposition of the main contradictions between the two, and the scene fire safety level is high, and the space requirements are large.
