Abstract

A battery includes at least one battery module that has several battery cells arranged next to each other on a support plate. The battery module is arranged with the support plate on a base plate of the battery or on a base plate of a lower unit of the battery. The support plate and the base plate are fixed together by at least one fixing system that includes at least two fixing elements engaging in each other. The first fixing element is arranged on the battery module and the second fixing element is arranged on the base plate. A motor vehicle includes the battery.

First claim

The invention claimed is:

1. A battery, comprising:
a support plate;
a base plate; and
a battery module, including:
a plurality of battery cells arranged next to one another on the support plate; and
a pressure plate arranged on an end face of only one battery cell of the plurality of battery cells,

wherein the battery module is arranged by way of the support plate on the base plate,
wherein the support plate and the base plate are connected to one another in a stationary manner by way of at least one fastening system, and
wherein the fastening system has a first fastening partner and a second fastening partner that latch into one another, the first fastening partner being arranged on the pressure plate of the battery module, and the second fastening partner being arranged on the base plate.

2. The battery as claimed in claim 1 , wherein at least one interlocking connection in a direction perpendicular to the base plate is established by the first and second fastening partners.

3. The battery as claimed in claim 1 , wherein the second fastening partner is formed by a cutout in the base plate and an area of the base plate that borders the cutout.

4. The battery as claimed in claim 3 , wherein the first fastening partner is a spring arm that projects into the cutout and engages behind that area of the base plate that borders the cutout.

5. The battery as claimed in claim 3 , wherein the cutout is arranged in the base plate beneath the battery module.

6. The battery as claimed in claim 1 , wherein the first fastening partner is a projection, and the second fastening partner is a spring arm that engages behind the projection.

7. The battery as claimed in claim 1 , further comprising an intermediate layer arranged between the battery module and the base plate, the intermediate layer being configured to apply a pretensioning force between the battery module and the base plate.

8. The battery as claimed in claim 2 , wherein one or more of (i) the first fastening partner is integrally formed with the pressure plate and (ii) the second fastening partner is integrally formed with the base plate.

9. A motor vehicle, comprising:
a drive system; and
a battery connected to the drive system, the battery including:
a support plate;
a base plate; and
a battery module, including:
a plurality of battery cells arranged next to one another on the support plate; and
a pressure plate arranged on an end face of only one battery cell of the plurality of battery cells,

wherein the battery module is arranged by way of the support plate on the base plate,
wherein the support plate and the base plate are connected to one another in a stationary manner by way of at least one fastening system, and
wherein the fastening system has a first fastening partner and a second fastening partner that latch into one another, the first fastening partner being arranged on the pressure plate of the battery module, and the second fastening partner being arranged on the base plate.

10. A battery, comprising:
a support plate;
a base plate; and
a battery module including a plurality of battery cells arranged next to one another on the support plate,
wherein the battery module is arranged on the base plate by way of the support plate,
wherein the support plate and the base plate are connected to one another in a stationary manner by way of at least one fastening system, and
wherein the fastening system includes a first fastening partner and a second fastening partner that latch into one another,
wherein the second fastening partner is formed by a cutout in the base plate and an area of the base plate that borders the cutout, and
wherein the first fastening partner is a spring arm that projects into the cutout and engages behind that area of the base plate that borders the cutout.

11. The battery as claimed in claim 10 , wherein at least one interlocking connection in a direction perpendicular to the base plate is established by the first and second fastening partners.

12. The battery as claimed in claim 10 , wherein the first fastening partner is arranged on the support plate of the battery module.

13. The battery as claimed in claim 10 , wherein the first fastening partner is arranged on a pressure plate of the battery module, said pressure plate being arranged next to an outer one of the battery cells.

14. The battery as claimed in claim 10 , wherein the cutout is arranged in the base plate beneath the battery module.

15. The battery as claimed in claim 10 , further comprising an intermediate layer arranged between the battery module and the base plate, the intermediate layer being configured to apply a pretensioning force between the battery module and the base plate.
