Abstract

This disclosure details exemplary battery pack designs for use in electrified vehicles. An exemplary battery pack may include an enclosure assembly, one or more battery arrays housed within the enclosure assembly, a first battery internal component (e.g., an array holding device, heat exchanger plate, tray, etc.) adjacent to the battery array, a mounting bracket mounted to the first battery internal component, and a second battery internal component (e.g., a wiring harness of an electrical distribution system) elevated above the first battery internal component by the mounting bracket.

First claim

What is claimed is:

1. A battery pack, comprising:
an enclosure assembly;
a first battery array housed within the enclosure assembly;
a first battery internal component adjacent to the first battery array;
a mounting bracket secured to the first battery internal component;
a second battery internal component elevated above the first battery internal component by the mounting bracket; and
a retainer device secured to the mounting bracket,
wherein the second battery internal component is connected to the retainer device by a piece of tape or by flexible clip arms of the retainer device.

2. The battery pack as recited in claim 1 , wherein the first battery internal component is an array holding device that is received over at least a portion of the first battery array to retain the first battery array relative to a tray of the enclosure assembly.

3. The battery pack as recited in claim 1 , wherein the first battery internal component is a heat exchanger plate.

4. The battery pack as recited in claim 1 , wherein the first battery internal component is a portion of a tray of the enclosure assembly.

5. The battery pack as recited in claim 1 , wherein the second battery internal component is a wiring harness of an electrical distribution system.

6. The battery pack as recited in claim 5 , wherein the wiring harness connects between the first battery array and either a bussed electrical center or a battery electric control module.

7. The battery pack as recited in claim 1 , wherein the mounting bracket is secured to the first battery internal component by at least one fastener.

8. The battery pack as recited in claim 1 , wherein the mounting bracket includes a lower plateau, an upper plateau spaced from the lower plateau along a Z-axis of the battery pack, and a bridge that connects the lower and upper plateaus, wherein the retainer device is mounted to the upper plateau.

9. A battery pack, comprising:
an enclosure assembly;
a first battery array housed within the enclosure assembly;
an array holding device received over at least a portion of the first battery array to retain the first battery array relative to the enclosure assembly;
a mounting bracket secured to the array holding device;
a retainer device secured to the mounting bracket; and
a wiring harness connected to the retainer device,
wherein the array holding device, the mounting bracket, and the retainer device are each separate and distinct components of the battery pack.

10. The battery pack as recited in claim 9 , wherein the wiring harness includes a first connector that is plugged into a second connector that protrudes from a lateral side surface of the first battery array.

11. The battery pack as recited in claim 10 , wherein the first connector extends from a sense lead of the wiring harness.

12. The battery pack as recited in claim 9 , wherein the array holding device is received over a foot of an array frame of the first battery array.

13. The battery pack as recited in claim 9 , wherein the mounting bracket includes a lower plateau, an upper plateau spaced from the lower plateau along a Z-axis of the battery pack, and a bridge that connects the lower and upper plateaus, wherein the retainer device is mounted to the upper plateau of the mounting bracket.

14. The battery pack as recited in claim 13 , wherein the mounting bracket includes a bead formed in the bridge and configured for increasing a stiffness of the mounting bracket.

15. The battery pack as recited in claim 13 , wherein the mounting bracket includes an anti-rotation tab that protrudes from the lower plateau at an opposite end of the lower plateau from the bridge, wherein the anti-rotation tab contacts a side surface of the array holding device.

16. The battery pack as recited in claim 13 , wherein the lower plateau includes a first opening for receiving a fastener for mounting the mounting bracket to the array holding device, and the upper plateau includes a second opening for receiving an anchoring prong of the retainer device.

17. The battery pack as recited in claim 9 , wherein the retainer device includes an anchoring prong and a flat plate, and the wiring harness is connected to the flat plate by an adhesive or a tape.

18. The battery pack as recited in claim 9 , wherein the retainer device includes an anchoring prong and a pair of flexible clip arms that are configured to receive and retain the wiring harness.

19. A battery pack, comprising:
an enclosure assembly;
a first battery array housed within the enclosure assembly;
a first battery internal component adjacent to the first battery array;
a mounting bracket secured to the first battery internal component; and
a second battery internal component elevated above the first battery internal component by the mounting bracket,
wherein the mounting bracket includes a lower plateau, an upper plateau spaced from the lower plateau along a Z-axis of the battery pack, and a bridge that connects the lower and upper plateaus.
