Abstract

The invention relates to a battery system for driving an electric motor of a hybrid vehicle or of an electric vehicle. To improve the comfort, performance and/or the range of the vehicle, the battery system has an exchangeable component battery system (10).

Claims

1. A battery system having at least one battery for driving an electric motor of a hybrid vehicle or of an electric vehicle, characterized in that the battery system comprises an exchangeable component battery system.

2. The battery system of claim 1, wherein the exchangeable component battery system comprises at least one exchangeable auxiliary battery and a supply battery.

3. A motor vehicle having an electric motor that can be driven by a battery system, the battery system comprising a supply battery and at least one exchangeable auxiliary battery.

4. A motor vehicle comprising:

an electric power source having a supply battery and at least on auxiliary battery;

a trunk compartment having a bottom delimited by a movable trunk compartment floor, an accommodation space provided beneath the trunk compartment floor and configured for accommodating the at least one auxiliary battery.

5. The motor vehicle of claim 4, wherein the trunk compartment floor is vertically adjustable to change dimensions of the accommodation space in accordance with whether the auxiliary battery is required.

6. The motor vehicle of claim 5, wherein the trunk compartment floor is moveable to a loading position defining a maximum possible trunk compartment volume.

7. The motor vehicle of claim 6, wherein the trunk compartment floor is moveable up to a battery position defining the accommodation space that accommodates the auxiliary battery.

8. The motor vehicle of claims 7, wherein the trunk compartment floor is manually adjustable vertically.

9. The motor vehicle of claim 7, further comprising a motor for vertically adjusting positions of the trunk compartment floor.

10. The motor vehicle of claim 4, further comprising an opening at a lower part of the accommodation space for accessing the accommodation space from below to insert, remove or exchange the auxiliary battery.
