Between 300 and the waiting area, for removing, installing and transporting the battery pack of the vehicle 900.

The vehicle-carrying platform 200 is used to carry the vehicle 900 whose battery pack is to be replaced. The battery-changing vehicle 900 enters the battery-changing station and stops at the vehicle-carrying platform 200 . If the battery pack has a new battery pack, the battery swapping device 100 removes the old battery pack on the vehicle 900 and transports it to the charging area 300 for charging. The second channel is moved out of the swap station, so as to prevent the battery pack in question from burning or exploding and causing damage to other battery packs or vehicles inside the swap station.

In the charging area 300 are placed charging racks, elevators, main control boxes and other equipment. The charging racks are used for accommodating battery packs and charging old battery packs. The elevator is used for exchanging battery packs with the battery swapping device 100 and removing the battery packs from the charging racks. Take it out or put it in the charging stand.
