The invention relates to a system for replacing a battery of a ground transportation vehicle, particularly of an unmanned heavy-duty transportation vehicle for ISO containers. The system includes storage spaces for batteries, at least one ground transportation vehicle having a receiving space for a replaceable battery, and at least one loading and unloading device for transporting batteries between the storage spaces and the receiving space of the transport vehicle in a replacement area. The storage space and the receiving space may include respective centering elements such that the battery is aligned relative to the storage space or the receiving space in response to the loading motion of the loading and unloading device.

1. A battery changing system for use in changing a battery of a ground transport vehicle, said system comprising: storage areas for batteries;at least one ground transport vehicle with a receiving area for a replaceable lead battery having a weight of at least 6 tons, wherein said transport vehicle is a heavy-duty automated guided vehicle for ISO-containers;a changing area for supporting the at least one ground transport vehicle;at least one loading and unloading device for transporting the batteries between the storage areas and the receiving area of the at least one transport vehicle supported on the changing area, wherein the loading and unloading device is configured to move the batteries in a lifting and lowering direction for mounting or dismounting the batteries in the storage areas or in the receiving area;centering elements positioned in the storage area and the receiving area, the centering elements configured to orient the battery relative to the storage area or the receiving area in response to the lowering movement of the loading and unloading device;support elements disposed on the battery, the support elements laterally protruding on both sides of the battery;carrier rails disposed in the storage area;support rails disposed in the receiving area, wherein the receiving area is open on both sides of the transport vehicle; andwherein the support elements of the battery are configured to lie on the carrier rails or the support rails when the battery is positioned in the storage area or the receiving area. 2. The system as claimed in claim 1, wherein the battery is configured to be suspended in and unhooked from the storage area or the receiving area by the loading and unloading device. 3. The system as claimed in claim 1, wherein the loading and unloading device is configured to permit the battery to move horizontally to facilitate centering during the lowering movement of the loading and unloading device and when the centering elements are in engagement with the battery. 4. The system as claimed in claim 1, wherein the battery is configured to be electrically separated or electrically contacted automatically in the storage areas and the receiving areas upon movement of the battery in the lifting and lowering directions, respectively. 5. The system as claimed in claim 1, wherein the loading and unloading device has a support arm for the battery, which is able to travel laterally in a mounting and dismounting direction in and out of the storage areas and in the direction of the changing area. 6. The system as claimed in claim 1, further comprising a distribution vehicle that is configured to operate in an automatic mode. 7. The system as claimed in claim 1, further comprising: a plurality of the storage areas disposed next to each other;a distribution vehicle for supporting the loading and unloading device, the distribution vehicle configured to travel along the storage areas and along a travel path; andwherein at least one changing area for the transport vehicle is disposed adjoining the travel path. 8. The system as claimed in claim 7, wherein the at least one changing area is disposed opposite the storage areas with respect to the travel path of the distribution vehicle. 9. The system as claimed in claim 7, wherein the at least one changing area is disposed adjoining the travel path and as an extension of the storage areas. 10. The system as claimed in claim 7, comprising more than one changing area disposed opposite the storage areas with respect to the travel path or adjoining the travel path and as an extension of the storage areas. 11. The system as claimed in claim 1, wherein a shelf unit with a plurality of levels arranged one above the other comprises the storage areas, and wherein the distribution vehicle is configured as a shelf unit serving apparatus. 12. The system as claimed in claim 1, further comprising sensors disposed in the region of the changing areas, the sensors configured to determine the position of the transport vehicle relative to the loading and unloading device so that the orientation of the loading and unloading device can be corrected with respect to the transport vehicle on the changing area with the aid of the determined position of the transport vehicle. 13. The system as claimed in claim 3, wherein the battery is configured to be electrically separated or electrically contacted automatically in the storage areas and the receiving areas upon movement of the battery in the lifting and lowering directions, respectively. 14. The system as claimed in claim 13, wherein the loading and unloading device has a support arm for the battery, which is able to travel laterally in a mounting and dismounting direction in and out of the storage areas and in the direction of the changing area. 15. The system as claimed in claim 1, further comprising a distribution vehicle that is configured to operate in an automatic mode. 16. The system as claimed in claim 15, further comprising: a plurality of the storage areas disposed next to each other;a distribution vehicle for supporting the loading and unloading device, the distribution vehicle configured to travel along the storage areas and along a travel path; andwherein at least one changing area for the transport vehicle is disposed adjoining the travel path. 17. The system as claimed in claim 16, wherein the at least one changing area is disposed opposite the storage areas with respect to the travel path of the distribution vehicle. 18. The system as claimed in claim 17, wherein the at least one changing area is disposed adjoining the travel path and as an extension of the storage areas. 19. The system as claimed in claim 18, comprising more than one changing area disposed opposite the storage areas with respect to the travel path or adjoining the travel path and as an extension of the storage areas. 20. The system as claimed in claim 19, wherein a shelf unit with a plurality of levels arranged one above the other comprises the storage areas, and wherein the distribution vehicle is configured as a shelf unit serving apparatus. 21. The system as claimed in claim 20, further comprising sensors disposed in the region of the changing areas, the sensors configured to determine the position of the transport vehicle relative to the loading and unloading device so that the orientation of the loading and unloading device can be corrected with respect to the transport vehicle on the changing area with the aid of the determined position of the transport vehicle.
