Description

Technical Field

[0001] The utility model relates to the technical field of battery replacement, and more specifically, to a battery replacement station. Background Art

[0002] With the development of new energy technologies, the demand for battery swap stations is increasing. There are many types of battery swap stations. The battery boxes in the main body of the station need to be charged or discharged, which will inevitably increase the temperature of the battery box. There are many high-voltage and low-voltage lines in the battery box, which inevitably leads to the battery box overheating or short-circuiting and burning. If the burning battery box is not handled in time, it will affect other battery boxes in the station. Some battery swap stations are equipped with a battery cavity and a fire-fighting cavity in the shell. The battery cavity is used to place the battery box. The fire-fighting cavity and the battery cavity are located in the same shell. When a thermal runaway battery box is placed in the fire-fighting cavity, the heat will be transferred to one side of the battery cavity, affecting other normal battery boxes in the shell of the station.
