MULTI CHARGING STATION FOR A STORAGE SYSTEM

A storage system includes a bin storing grid for storing storage bins in columns of the grid, a base with rails provided on top of the grid, and a vehicle configured to move vertically along the rails in a vehicle operating space. The system includes a charging station assembly for charging the rechargeable power sources of the vehicle. The charging station assembly includes a plurality of charging stations located above each other. Each charging station includes a power source carrier for carrying one of the respective power sources. A charging station support is supporting the charging stations in relation to the base. A transportation device is connected to the base for vertical displacement of the charging stations in relation to the base. A holding device is configured to selectively hold one of the charging stations at an exchange location in which the power source carrier of the one charging station is a predetermined height above the base. The transportation device is configured to vertically displace other charging stations to an upper location above the vehicle operating space or to a lower location below the vehicle operating space.
