Abstract

The invention relates to a battery module housing ( 200 1 , . . . 200 4 ) for a battery pack ( 10 ), characterized in that: the battery module housing ( 200 1 , . . . 200 4 ) can contain a large number of battery cells ( 100 111 , . . . 100 432 ) which each have a large wall surface ( 120 1 , 120 2 ) and a small wall surface ( 130 1 , 130 2 ), of which small wall surface the surface area is less than a surface area of the large wall surface ( 120 1 , 120 2 ), wherein the battery cells ( 100 119 , 100 129 , 100 132 , 100 142 , 100 219 , 100 229 , 100 232 , 100 242 , 100 319 , 100 329 , 100 332 , 100 342 , 100 419 , 100 432 ) which can be arranged adjacent to outer sides of the battery pack ( 10 ) can be oriented in such a way that their large wall surfaces ( 120 1 , 120 2 ) run along the outer sides, so that a force which acts on one of the outer sides can initially be received by one of the large wall surfaces ( 120 1 , 120 2 ), and also to a battery module ( 20 1 , 20 4 ), to a battery pack ( 10 ), to a battery, to a vehicle and also to a method for producing a battery module ( 20 1 , . . . 20 4 ), a battery pack ( 10 ) and a battery.

First claim

The invention claimed is:

1. A battery pack comprising:
four outer sides that are configured to extend vertically during normal use of the battery pack,
a plurality of battery module housings, and
a plurality of battery cells, each of the battery module housings containing at least two of the battery cells, and each of the battery cells having a large wall surface and a small wall surface, a surface area of the small wall surface being less than a surface area of the large wall surface, wherein the battery cells which are arranged adjacent to the four outer sides of the battery pack are oriented in such a way that only the large wall surfaces of the battery cells adjacent to the four outer sides of the battery pack run along the four outer sides, so that a force which acts on one of the four outer sides can initially be received by one of the large wall surfaces of one of the battery cells adjacent to the four outer sides of the battery pack.

2. The battery pack according to claim 1 , wherein at least one of the battery module housings includes
a receptacle or receiving chamber for receiving a device for monitoring or controlling the plurality of battery cells.

3. The battery pack according to claim 2 , wherein
the device for monitoring or controlling said plurality of battery cells is a battery disconnect unit.

4. The battery pack according to claim 1 , comprising a battery module, wherein the battery module includes:
a device for monitoring or controlling the plurality of battery cells.

5. The battery pack according to claim 4 , wherein
the device for monitoring or controlling said plurality of battery cells is a battery disconnect unit.

6. A battery, comprising:
the battery pack according to claim 1 .

7. A vehicle, comprising:
the battery according to claim 6 .

8. A method for producing a battery pack having four outer sides that extend vertically during normal use of the battery pack, the method comprising:
providing a plurality of battery module housings,
providing a plurality of battery cells each having a large wall surface and a small wall surface, a surface area of the small wall surface being less than a surface area of the large wall surface, and
arranging at least two of the plurality of battery cells in each of the plurality of battery module housings, wherein the battery cells which are arranged adjacent to four outer sides of the battery pack are oriented in such a way that only the large wall surfaces of the battery cells which are arranged adjacent to the four outer sides of the battery pack run along the four outer sides, so that a force which acts on one of the outer sides can initially be received by one of the large wall surfaces of the battery cells which are arranged adjacent to the four outer sides of the battery pack.

9. The method according to claim 8 , furthermore comprising:
providing a device for the monitoring and controlling of battery cells and
arranging the device for monitoring and controlling said battery cells in the battery module housings.

10. The method according to claim 9 , wherein:
the device for the monitoring and controlling of battery cells is a battery disconnect unit,
the battery disconnect unit comprises a first circuit breaker and a second circuit breaker, or
the first circuit breaker and the second circuit breaker are arranged at right angles to one another, so that they cannot be influenced in the same way by the applied force.

11. A method for producing a battery pack, characterized by:
providing the battery pack according to claim 1 ,
providing a battery module including one of the battery module housings,
providing a crash frame including the four outer sides, and
arranging the battery module in the crash frame.

12. The method for producing a battery pack according to claim 11 , furthermore comprising:
providing a circuit board,
arranging the circuit board on the battery module and
electrically coupling connection contacts of the circuit board to electrical terminals ( 150 , 155 ) of the battery cells.

13. A method for producing a battery, characterized by:
providing the battery pack according to claim 1 ,
providing a battery housing, and
arranging the battery pack in the battery housing.

14. The battery pack of claim 1 , wherein the battery module housing includes a plurality of battery cell chambers for receiving the plurality of battery cells.

15. The battery pack of claim 3 , wherein the battery disconnect unit comprises a first circuit breaker and a second circuit breaker.

16. The battery pack of claim 15 , wherein the first circuit breaker and the second circuit breaker are arranged at right angles to one another so that they cannot be influenced in the same way by the applied force.

17. The battery pack of claim 5 , wherein the battery disconnect unit comprises a first circuit breaker and a second circuit breaker which are contained by one of the battery module housings.

18. The battery pack of claim 17 , wherein the first circuit breaker and the second circuit breaker are arranged at right angles to one another so that they cannot be influenced in the same way by the applied force.

19. A battery pack comprising:
four outer sides that are configured to extend vertically during normal use of the battery pack,
a plurality of battery cells contained by the battery pack and each having a large wall surface and a small wall surface, a surface area of the small wall surface being less than a surface area of the large wall surface, wherein the battery cells which are arranged adjacent to the four outer sides of the battery pack are oriented in such a way that only the large wall surfaces of the battery cells adjacent to the four outer sides of the battery pack run along the four outer sides, so that a force which acts on one of the four outer sides can initially be received by one of the large wall surfaces of one of the battery cells adjacent to the four outer sides of the battery pack,
