Abstract

An exemplary connector assembly includes, among other things, a bottom brace at least partially disposed beneath an enclosure of a battery pack to provide an open area vertically between the enclosure and a floor of the bottom brace. A side brace is disposed alongside the enclosure to provide an open area laterally between the enclosure and a floor of the side brace. A bracket connects the bottom and side braces to a vehicle structure. An exemplary battery pack connection method includes, among other things, supporting an enclosure of a battery pack with a bottom brace at least partially disposed beneath the enclosure. The method includes supporting the enclosure with a side brace that is at least partially disposed alongside the enclosure. The method further includes connecting the bottom and side braces to a vehicle structure through a bracket.

First claim

What is claimed is:

1. A connector assembly, comprising:
a bottom brace at least partially disposed beneath an enclosure of a battery pack to provide an open area vertically between the enclosure and a floor of the bottom brace;
a side brace at least partially disposed alongside the enclosure to provide an open area laterally between the enclosure and a floor of the side brace; and
a bracket connecting the bottom and side braces to a vehicle structure, the bottom and side braces each directly secured to the enclosure.

2. The connector assembly of claim 1 , wherein the bottom brace is a tube having a transverse cross-section that is circumferentially continuous.

3. The connector assembly of claim 1 , wherein the bottom brace is a first bottom brace and further comprising a second bottom brace at least partially disposed beneath the enclosure to provide an open area vertically between the enclosure and the second bottom brace, the first and second bottom braces laterally spaced a distance from each other.

4. The connector assembly of claim 3 , further comprising a third bottom brace at least partially disposed beneath the enclosure to provide an open area vertically between the enclosure and a floor of the third bottom brace, the third bottom brace extending longitudinally from a position adjacent the first bottom brace to a position adjacent the second bottom brace.

5. The connector assembly of claim 4 , wherein the first, second, and third bottom braces are each a tube having a transverse cross-section that is circumferentially continuous.

6. The connector assembly of claim 1 , wherein the side brace is directly connected to a lateral side of the enclosure and, where the side brace is directly connected to the lateral side, the side brace has a transverse cross-section that is circumferentially continuous.

7. The connector assembly of claim 1 , wherein the side brace is directly connected to a lateral side of the enclosure and, where the side brace is directly connected to the lateral side, the side brace has a transverse cross-section that has a cup-shape and is circumferentially discontinuous.

8. The connector assembly of claim 1 , wherein the side brace extends from a lateral side of the enclosure to a vertical bottom of the enclosure where the side brace interfaces directly with the bottom brace.

9. The connector assembly of claim 8 , wherein, where the side brace interfaces directly with the bottom brace, the side brace has a transverse cross-section that is circumferentially continuous.

10. The connector assembly of claim 1 , wherein the side brace is disposed entirely above a bottom of the enclosure such that no portion of the side brace extends vertically below the bottom.

11. A connector assembly, comprising:
a bottom brace at least partially disposed beneath an enclosure of a battery pack to provide an open area vertically between the enclosure and a floor of the bottom brace;
a side brace at least partially disposed alongside the enclosure to provide an open area laterally between the enclosure and a floor of the side brace; and
a bracket connecting the bottom and side braces to a vehicle structure, wherein the bracket is directly connected to both the bottom and side braces.

12. The connector assembly of claim 11 , wherein the bracket is a single, continuous bracket.

13. The connector assembly of claim 1 , further comprising the enclosure of the battery pack disposed outside of a vehicle, the enclosure is connected through the bottom brace, side brace, and the bracket to an underbody of the vehicle.

14. The connector assembly of claim 11 , wherein the bottom brace is a tube having a transverse cross-section that is circumferentially continuous.

15. The connector assembly of claim 11 , wherein the side brace is directly connected to a lateral side of the enclosure and, where the side brace is directly connected to the lateral side, the side brace has a transverse cross-section that has a cup-shape and is circumferentially discontinuous.

16. The connector assembly of claim 11 , wherein the side brace is directly connected to a lateral side of the enclosure and, where the side brace is directly connected to the lateral side, the side brace has a transverse cross-section that has a cup-shape and is circumferentially continuous.

17. A connector assembly, comprising:
a bottom brace providing an open area vertically between an enclosure of a battery pack and a bottom brace floor;
a side brace providing an open area laterally between the enclosure and a side brace floor, the side brace extending to a vertical bottom of the enclosure to interface directly with the bottom brace; and
a bracket connecting the bottom and side braces to a vehicle structure.

18. The connector assembly of claim 13 , wherein the bracket is a single, continuous bracket.

19. The connector assembly of claim 13 , wherein the bottom brace is a first bottom brace and further comprising a second bottom brace at least partially disposed beneath the enclosure to provide an open area vertically between the enclosure and the second bottom brace, the first and second bottom braces laterally spaced a distance from each other.
