Abstract

A battery pack mounting system includes, among other things, an outboard bracket connecting a battery pack to a vehicle underbody, a first inboard bracket connecting the battery pack to the vehicle underbody, and a second inboard bracket connecting the battery pack to a tunnel of the vehicle underbody.

First claim

What is claimed is:

1. A battery pack mounting system, comprising:
an outboard bracket connecting a battery pack to a vehicle underbody;
a first inboard bracket connecting the battery pack to the vehicle underbody; and
a second inboard bracket connecting the battery pack to a tunnel of the vehicle underbody,
wherein the first inboard bracket connects the battery pack to a midrail of the vehicle underbody.

2. The battery pack mounting system of claim 1 , wherein the outboard bracket connects the battery pack to a rocker of the vehicle underbody.

3. A battery pack mounting system, comprising:
an outboard bracket connecting a battery pack to a vehicle underbody;
a first inboard bracket connecting the battery pack to the vehicle underbody; and
a second inboard bracket connecting the battery pack to a tunnel of the vehicle underbody,
wherein the outboard bracket connects the battery pack to a rocker of the vehicle underbody,
wherein the outboard bracket includes a plurality of legs extending from a platform, wherein, along a horizontally facing outboard side of the battery pack, each of the legs within the plurality of legs is spaced a distance from the remaining legs within plurality of legs.

4. The battery pack mounting system of claim 3 , wherein the plurality of legs includes at least four legs.

5. The battery pack mounting system of claim 3 , wherein the platform extends along a vertically lower side of the battery pack.

6. The battery pack mounting system of claim 1 , wherein the first inboard bracket is directly connected to a horizontally facing inboard side of the battery pack and further directly connected to a downwardly facing side of the midrail.

7. The battery pack mounting system of claim 1 , wherein the second inboard bracket connects the battery pack to a horizontally facing side of the tunnel.

8. The battery pack mounting system of claim 7 , wherein the second inboard bracket is directly connected to the tunnel and further directly connected to a vertically lower side of the battery pack.

9. The battery pack mounting system of claim 7 , wherein the tunnel is a driveshaft tunnel.

10. The battery pack mounting system of claim 1 , further comprising at least one mechanical fastener that extends horizontally through an aperture in second inboard bracket to connect the second inboard bracket to the tunnel.

11. The battery pack mounting system of claim 1 , further comprising an aft bracket that connects the battery pack to the vehicle underbody.

12. The battery pack mounting system of claim 1 , further comprising a liquid fuel tank on a passenger or driver side of the tunnel, the battery pack on the other of the passenger or driver side of the tunnel.

13. A battery pack mounting method, comprising:
connecting a battery pack to a vehicle underbody with an outboard bracket;
connecting the battery pack to the vehicle underbody with a first inboard bracket; and connecting the battery pack to a tunnel of the vehicle underbody with a second inboard bracket,
wherein the first inboard bracket is connected to the battery pack and a midrail of the vehicle underbody.

14. The battery pack mounting method of claim 13 , wherein the battery pack is disposed on a passenger side or a driver side of the tunnel.

15. The battery pack mounting method of claim 14 , wherein a liquid fuel tank is disposed on the other of the passenger side or the driver side of the tunnel.

16. The battery pack mounting method of claim 13 , wherein the outboard bracket is connected to the battery pack and a rocker of the vehicle underbody.

17. The battery pack mounting method of claim 16 , wherein the connecting of the outboard bracket to the rocker comprises connecting a plurality of legs of the outboard bracket to the rocker, and further comprises connecting a platform of the outboard bracket to a vertically lower side of the battery pack.
