Abstract
A replacement station for the traction batteries of electric vehicles, preferably of passenger vehicles, which are arranged such that they can be replaced from underneath, alongside a vehicle axis in the direction of travel, in the floor area of the electric vehicle. In order to replace the traction battery, the electric vehicle is positioned, guided by tracks, above a hatch which is provided in the floor of the replacement station, and the traction battery is replaced through the hatch. In order to considerably minimize the total time required for completely automatic replacement of the traction battery without any disturbances, and to maintain a high safety standard in operation during the process, the track guidance guides at least those wheels which are arranged on one longitudinal side of the electric vehicle and in that, during track guidance, the electric vehicle is moved automatically by a controlled external drive, which acts on the electric vehicle.
