Abstract

A battery module carrier includes: an H-beam including an upper flange, a web, and a lower flange; a first coolant hollow in the upper flange and extending along substantially an entire length of the upper flange; and a second coolant hollow in the web and extending along an entire length of the web.

First claim

What is claimed is:

1. A battery module carrier comprising:
an H-beam comprising an upper flange, a web, and a lower flange;
a first coolant hollow in the upper flange and extending along substantially an entire length of the upper flange in a longitudinal direction of the H-beam; and
a second coolant hollow in the web and extending along an entire length of the web in the longitudinal direction of the H-beam.

2. The battery module carrier according to claim 1 , further comprising a third coolant hollow in the lower flange and extending along substantially an entire length of the lower flange.

3. The battery module carrier according to claim 2 , wherein the second coolant hollow is fluidly connected to at least one of the first coolant hollow and the third coolant hollow.

4. The battery module carrier according to claim 2 , wherein the lower flange comprises a lower opening fluidly connected to the third coolant hollow.

5. The battery module carrier according to claim 1 , wherein the upper flange comprises an upper opening fluidly connected to the first coolant hollow.

6. The battery module carrier according to claim 1 , wherein the web comprises a coolant port configured to connect the second coolant hollow to an outer coolant circuit.

7. The battery module carrier according to claim 1 , wherein the upper flange and the lower flange are spaced from each other in a height direction of the H-beam such that accommodation spaces are formed between the upper flange and the lower flange on both sides of the web.

8. The battery module carrier according to claim 1 , wherein at least one of the upper flange, the web, and the lower flange of the H-beam is an extruded aluminum component.

9. A battery system comprising:
a battery module carrier comprising:
an H-beam comprising an upper flange, a web, and a lower flange;
a first coolant hollow in the upper flange and extending along substantially an entire length of the upper flange; and
a second coolant hollow arranged in the web and extending along an entire length of the web;

a first plurality of battery modules between the upper flange and the lower flange on a first side of the web; and
a second plurality of battery modules between the upper flange and the lower flange on a second side of the web.

10. The battery system according to claim 9 , further comprising:
a first side cover attached to the upper flange and/or the lower flange on the first side of the web and covering a surface of the first plurality of battery modules; and
a second side cover attached to the upper flange and/or the lower flange on the second side of the web and covering a surface of the second plurality of battery modules.

11. The battery system according to claim 9 , further comprising:
a third plurality of battery modules on a top surface of the upper flange; and
a top cover attached to the upper flange and covering a surface of the third plurality of battery modules.

12. The battery system according to claim 11 , further comprising:
a fourth plurality of battery modules on a bottom surface of the lower flange; and
a bottom cover attached to a lower surface of the lower flange and covering a surface of the fourth plurality of battery modules.

13. The battery system according to claim 12 , further comprising a control electronics assembly between the upper flange and the lower flange on one side of the web, the control electronics assembly comprises a power port and/or a signal port and is electrically and/or electronically connected to at least one of the first plurality of battery modules, the second plurality of battery modules, the third plurality of battery modules, and the fourth plurality of battery modules.

14. The battery system according to claim 9 , further comprising a front plate attached to a front face of the H-beam.

15. The battery system according to claim 14 , further comprising further comprising a third coolant hollow in the lower flange and extending along substantially an entire length of the lower flange; and
an end plate attached to an end face of the H-beam.

16. The battery system according to claim 15 ,
wherein at least one of the front plate and the end plate is configured to fluidly connect at least one of the first coolant hollow, the second coolant hollow, and the third coolant hollow to an external coolant circuit,
wherein at least one of the front plate and the end plate is configured to fluidly connect at least two of the first coolant hollow, the second coolant hollow, and the third coolant hollow to each other, and
wherein at least one of the front plate and the end plate is configured to fluid tightly seal at least one of the first coolant hollow, the second coolant hollow, and the third coolant hollow.

17. The battery system according to claim 15 , wherein at least one of the front plate and the end plate is configured to fluidly connect at least one of the first coolant hollow, the second coolant hollow, and the third coolant hollow to an external coolant circuit.

18. The battery system according to claim 15 , wherein at least one of the front plate and the end plate is configured to fluidly connect at least two of the first coolant hollow, the second coolant hollow, and the third coolant hollow to each other.

19. The battery system according to claim 15 , wherein at least one of the front plate and the end plate is configured to fluid tightly seal at least one of the first coolant hollow, the second coolant hollow, and the third coolant hollow.

20. The battery system according to claim 15 , wherein one of the front plate and the end plate is configured to fluidly connect at least one of the first coolant hollow, the second coolant hollow, and the third coolant hollow to an external coolant circuit, and
wherein the other one of the front plate and the end plate is configured to fluidly connect at least two of the first coolant hollow, the second coolant hollow, and the third coolant hollow to each other.

21. A battery module carrier comprising:
an H-beam comprising an upper flange, a web, and a lower flange;
a first coolant hollow in the upper flange and extending along substantially an entire length of the upper flange;
a second coolant hollow in the web and extending along an entire length of the web; and
an end plate connected to the H-beam and comprising a coolant connecting channel fluidly connecting the first coolant hollow and the second coolant hollow to each other.
