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.

First claim

What is claimed is:

1. A replaceable battery module for an electrically driven vehicle having a vehicle frame supporting a seat and an electromotive drive, the replaceable battery module comprising:
a mounting plate carrying a battery unit on a first side of the plate;
a bracket configured to be detachably secured to a bearing structure on the vehicle frame for securing the battery unit between the mounting plate, the bracket and the bearing structure and locating the front seat between the battery unit and the electromotive drive; and
a plurality of threaded fasteners extending through the mounting plate and the bracket for detachably securing the bracket to a plurality of corresponding provided on the bearing structure;
wherein the replaceable battery module is hermetically separated from an interior of the vehicle.

2. The replaceable battery module according to claim 1 , wherein the at least one plurality of threaded fasteners and/or the plurality of threaded boreholes prescribe an assembly or disassembly direction that is essentially aligned in a vertical direction of the electrically driven vehicle.

3. The replaceable battery module according to claim 1 , wherein a lower side of the mounting plate facing away from the battery unit is designed as a floor cladding section of the electrically driven vehicle.

4. The replaceable battery module according to claim 1 , wherein the mounting plate is integrated essentially flush in a floor cladding of the electrically driven vehicle when the replaceable battery module is in a mounting position on the electrically driven vehicle.

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

6. The replaceable battery module according to claim 1 , wherein the replaceable battery module is configured to be centrally located in relation to a transverse direction of the motor vehicle.

7. The replaceable battery module according to claim 1 , wherein the replaceable battery module further comprises at least one battery unit hermetically encapsulated from the environment.

8. A motor vehicle comprising:
a vehicle frame having a floor and a bearing structure including a plurality of threaded boreholes;
a seat supported on the vehicle a above the floor in an interior of the motor vehicle;
an electric drive supported on the frame behind the seat; and
at least one replaceable battery module arranged on the floor of the motor vehicle and hermetically separated from the vehicle interior, the at least one replaceable battery module including:
a mounting plate carrying at least one battery unit on a first side of the plate;
a bracket detachably secured to the vehicle frame for securing the battery unit between the mounting plate, the bracket and the bearing structure and locating the front seat between the battery unit and the electromotive drive;
a plurality of threaded fasteners extending through the bracket and into corresponding plurality of threaded boreholes for detachably securing the bracket to the bearing structure.

9. The motor vehicle according to claim 8 , wherein the at least one replaceable battery module is centrally located 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 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.

11. The motor vehicle according to claim 8 , wherein the replaceable battery module further comprises at least one battery unit hermetically encapsulated from the environment.
