Abstract
An electric vehicle battery pack with a reinforced cover to better support vehicle cabin loads such as seat submerge loads, seat pitch loads, and the like. The cover has a number of reinforcing members affixed thereto and positioned over cross members of the battery pack frame. Loads imposed by the cabin are thus transferred to the reinforcing members and then to the rigid cross members. In this manner, battery packs of embodiments of the disclosure better support cabin loads applied thereto, improving their strength and better protecting more delicate components within the battery pack.
Claims20
A battery pack lid, the lid comprising:
- a panel comprising a first side and an opposing second side, the first side configured to face a battery pack frame comprising cross members extending between opposing sides of the battery pack frame;
- and
- a plurality of longitudinal reinforcing members affixed to the second side of the panel to extend across the cross members, wherein the plurality of longitudinal reinforcing members comprises at least one coupling that interfaces with at least one mounting point, and wherein the plurality of longitudinal reinforcing members are positioned to transfer loads to respective adjacent cross members when the panel is coupled to the battery pack frame.
An electric vehicle battery pack, the battery pack comprising:
- a frame having opposing sides, and a plurality of cross members each extending between the opposing sides, the opposing sides configured to support at least one battery module;
- a cover having a first surface facing the frame, and an opposing second surface;
- and
- at least one reinforcing member affixed to the second surface of the cover, the at least one reinforcing member positioned to extend across one or more cross members, the at least one reinforcing member further being positioned to transfer energy from an electric vehicle cabin to respective adjacent cross members, wherein the at least one reinforcing member comprises at least one coupling that interfaces with at least one mounting point.
A vehicle, comprising:
- a chassis;
- a vehicle cabin comprising mounting points;
- and
- a battery pack coupled to the chassis, the battery pack having a frame, cross members extending between opposing sides of the frame, a cover affixed to the frame, and at least one reinforcing member affixed to the cover and extending across at least two adjacent cross members, wherein the mounting points of the vehicle cabin are positioned above the at least one reinforcing member and wherein the at least one reinforcing member comprises at least one coupling that interfaces with at least one of the mounting points.
