A molded composite battery enclosure containing top and bottom composite covers attached together. The joined top and bottom composite cover structures form an enclose or open area for housing a battery system of battery cells and cooling devices. The composite battery enclosures are lightweight and made of materials that can function to absorb energy and insulate the battery housing area. The composite structures contain a core material adhered and sandwiched between skin fiber layers and an electromagnetic shielding material or resin incorporated into one of the composite structures.

A molded composite battery enclosure containing top and bottom composite covers having a formed cross member arranged between the top and bottom covers. The cross member is a formed member having a bottom portion shaped to accommodate interior surface features of the bottom composite cover. The cross member contains a flange portion for attaching to an interior surface of a battery enclosure. The flange portion of the cross member is split into separate sections to adapt to an interior surface contour of the top composite cover and an interior surface contour of the bottom composite cover.

The present invention relates to an outer module cover (1) with integrated gas discharge for a battery module (3) made up of battery cells (4), wherein the outer module cover (1) has a cover plate (8) in which rupture cut-outs (2) are provided that are through-openings in the cover plate (8), and the rupture cut-outs (2) are closed with a rupture disc (10) which is designed to open when acted upon by gas (7) escaping from a battery cell (4) in the event of a thermal failure in order to discharge the escaping gas (7) away from the battery module (3), wherein the outer module cover (1) is made of a high-temperature-resistant fiber-reinforced material.

An integrated battery cooling system includes a battery enclosure and a plate attached directly to the battery enclosure. The battery enclosure or the plate includes a wave-like cross-section that combines with the other to define coolant channels therebetween. The battery enclosure may have the wave-like structure and a flat cover plate may be attached to the top of the wave-like structure. A lower plate may include the wave-like structure and may be attached to the bottom of the battery enclosure. Coolant may pass through the coolant channels defined between the battery enclosure and the plate to draw heat away from battery cells housed within the battery enclosure.

A battery enclosure for a battery system includes a reinforcing layer including reinforcing fibers, a shielding layer, and a thermal protection layer. At least one of the reinforcing fibers, the shielding layer, and the thermal protection layer is consolidated using a thermoplastic resin into one of a body and a cover of the battery enclosure. The shielding layer is arranged on one side of the one of the body and the cover and the thermal protection layer is arranged on opposite side of the one of the body and the cover.
