A battery enclosure for a vehicle chassis having a base member with raised surface features on the upper surface outlining individual cells, each cell configured to receive at least one battery; a cover member having a plurality of depending surface features on the lower surface which are aligned with the surface features of the base member. The cover member includes a channel formed in the upper surface thereof, aligned with and extending along a length of the depending surface feature disposed on the bottom surface. A lattice support structure is also included which has a plurality of support members extending axially and transversely, wherein the lattice support structure is configured to be at least partially disposed within the channel of the cover member and mounted to the vehicle chassis. The lattice support member providing increased rigidity and a load distribution path for externally applied forces (e.g. crash events) to prevent or inhibit enclosure breakage or puncture.

A battery module incorporates features of both prismatic housings and metal foil laminate pouch housings, and is configured to receive and support electrochemical cells. The battery module housing includes a rigid tubular frame and flexible cover elements that are joined to the frame and close the open ends of the frame. The frame has an inner surface that faces the cells, an outer surface that is opposed to the inner surface, a first edge that joins the inner surface to the outer surface at one open end of the frame, and a second edge that joins the inner surface to the outer surface at the opposed open end of the frame. The first cover element overlies and closes the one open end of the frame and the second cover element overlies and closes the other open end of the frame.

A battery assembly according to an exemplary aspect of the present disclosure includes, among other things, an enclosure assembly defining an interior and a service panel integrally formed in the enclosure assembly. The service panel includes a ductile portion that is removable to access the interior.

Provided are a battery module end plate, a battery module, and a preparation method for a battery module end plate. The preparation method includes: providing a first blank and stamping the first blank to obtain a first plate body; providing a molding die and placing the first plate body into the molding die; providing a second blank and melting the second blank to obtain a molten material; and injecting the molten material into the molding die to allow the molten material to be wrapped around the first plate body, and obtaining the battery module end plate through cooling. The battery module end plate includes the first plate body and a second plate body formed by cooling the molten material and wrapped around the first plate body.
