Battery pack for a vehicle

1. A battery pack for a vehicle, the battery pack comprising:

a battery module comprising a plurality of secondary battery cells;

a carrier plate having a top surface and a side wall facing in a different direction than the top surface, the carrier plate comprising an integral first coupling element inside a coupling opening in the side wall of the carrier plate and an integral cooling channel structure having a cooling opening in the side wall of the carrier plate, the coupling opening being separate and spaced apart from the cooling opening in the side wall of the carrier plate, the battery module being on the top surface of the carrier plate;

a coupling member comprising:

a second coupling element configured to interact with the first coupling element inside the coupling opening to mechanically connect the coupling member and the carrier plate to each other; and

a mounting bracket; and

a coolant distributor in a fluid-tight connection with the integral cooling channel structure and extending into the cooling opening in the side wall of the carrier plate,

wherein the coolant distributor is removably retained in position relative to the carrier plate by the mounting bracket of the coupling member.

2. The battery pack of claim 1 , wherein the coupling member further comprises a support plate, and

wherein the mounting bracket is arranged on one side of the support plate, and the second coupling element is arranged on an opposite side of the support plate.

3. The battery pack of claim 2 , wherein the support plate, when fixed to the carrier plate, covers the side wall of the carrier plate, and

wherein the support plate, when fixed to the carrier plate, has a passage aligned with the cooling opening in the side wall of the carrier plate.

4. The battery pack of claim 3 , wherein the mounting bracket and the passage in the support plate are in the same section of the support plate.

5. The battery pack of claim 1 , wherein the coolant distributor comprises a tubular portion extending in a first direction and an intersection portion extending perpendicular to the tubular portion, the intersection portion being configured to establish fluid connection between the coolant distributor and the cooling opening in the integral cooling channel structure, and

wherein the mounting bracket comprises a clip element that, when closed, encircles and fixes the tubular portion of the coolant distributor.

6. The battery pack of claim 5 , wherein the coupling member further comprises a support plate, and

wherein the clip element comprises a first half shell and a second half shell, the first half shell being fixed to the support plate, the second half shell being moveably attached to one side of the first half shell for opening and closing the clip element.

7. The battery pack of claim 1 , wherein the first and second coupling elements are self-locking clamp elements.

8. The battery pack of claim 1 , wherein the second coupling element of the coupling member is configured to be friction-fit into the first coupling element in the side wall of the carrier plate to mechanically connect the coupling member to the carrier plate.

9. The battery pack of claim 1 , wherein, when the coupling member is connected to the carrier plate, the cooling opening in the side wall of the carrier plate is positionally between a distal end and a proximal end of the coupling member, and

wherein the coolant distributor extends from the proximal end of the coupling member to the distal end of the coupling member.
