Patent Images
1. A vehicle battery pack integration assembly, comprising:
- first and second vehicle structural side members located adjacent respective first and second sides of an electric vehicle, each of the vehicle structural side members comprising multiple longitudinal channels;
a battery pack enclosure mounted under the electric vehicle, wherein said battery pack enclosure comprises an enclosure top panel, an enclosure bottom panel, an internal cross member transverse to the electric vehicle, and a plurality of enclosure side members, wherein an outside of a first enclosure side member horizontally abuts the first vehicle structural side member, wherein an outside of a second enclosure side member horizontally abuts the second vehicle structural side member, wherein ends of the internal cross member abut respective insides of the first and second enclosure side members, wherein said battery pack enclosure is configured to hold a plurality of batteries, and wherein said battery pack enclosure is mounted between a passenger cabin floor panel and a driving surface; and
at least one insulating layer interposed between said battery pack enclosure and said passenger cabin floor panel, wherein said at least one insulating layer provides noise isolation, thermal isolation and vibration damping, and wherein said at least one insulating layer is compressed when said battery pack enclosure is mounted to said electric vehicle.
