Abstract

The present invention relates to a replaceable battery module for an electrically driven vehicle, with at least one bracket that can be detachably arranged on a bearing structure of the motor vehicle, and carries at least one battery unit.

Claims

1. A replaceable battery module for an electrically driven vehicle comprising:

at least one bracket that can be detachably arranged on a bearing structure of the electrically driven vehicle, and that carries at least one battery unit.

2. The replaceable battery module according to claim 1, wherein the at least one bracket exhibits at least one fastening element that corresponds with a counter-fastening element provided on the bearing structure.

3. The replaceable battery module according to claim 2, wherein the at least one fastening element and/or the counter-fastening element prescribe an assembly or disassembly direction that is essentially aligned in a vertical direction of the electrically driven vehicle.

4. The replaceable battery module according to claim 1, wherein the at least one bracket exhibits a mounting plate on which the at least one battery unit is detachably arranged.

5. The replaceable battery module according to claim 4, wherein a lower side of the mounting plate facing away from the replaceable battery module is designed as a floor cladding section of the electrically driven vehicle.

6. The replaceable battery module according to claim 4, wherein the mounting plate is integrated essentially flush in a floor cladding of the electrically driven vehicle with the replaceable battery module in a mounting position on the electrically driven vehicle.

7. The replaceable battery module according to claim 1, wherein at least one electrical connecting element is provided on the at least one bracket and/or on the at least one battery unit, and corresponds with an electrical connecting element formed on the electrically driven vehicle.

8. A motor vehicle with an electric drive and with at least one replaceable battery module that can be arranged on a floor of the motor vehicle, wherein the at least one replaceable battery module comprises:

at least one bracket that can be detachably arranged on a bearing structure of the motor vehicle, and that carries at least one battery unit.

9. The motor vehicle according to claim 8, wherein the at least one replaceable battery module is detachably arranged in a center in or on the motor vehicle in relation to a transverse direction of the motor vehicle.

10. The motor vehicle according to claim 8, wherein the at least one replaceable battery module is detachably arranged in a region lying between a front axis and a front seat relative to a longitudinal direction of the motor vehicle.

11. The motor vehicle according to claim 8, wherein the at least one replaceable battery module is detachably arranged so as to project underneath a passenger cabin and/or into a region of a front wheel in relation to a vertical direction of the motor vehicle.

12. The motor vehicle according to claim 8, wherein a drive as viewed in a traveling direction of the motor vehicle is situated behind a front seat.

13. The motor vehicle according to claim 8, wherein at least one front seat is at least regionally situated between a drive and the at least one replaceable battery module in relation to a longitudinal direction of the motor vehicle.
