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.

An encapsulation structure for preventing thermal damage to a battery includes a cooling module air guide formed on a front outer peripheral surface of a cooling module so as to protrude in a forward direction of a vehicle; an outside air line communicating with the cooling module air guide such that outside air flowing into the cooling module air guide is introduced through the outside air line; and a battery case formed to enclose the battery. The battery case communicates with the outside air line.

An automotive high-voltage energy accumulator includes a housing structure; a plurality of battery modules disposed in a housing space of the housing structure, wherein the housing structure closes the housing space at least in a lateral and/or downward manner; and a housing cover that closes the housing space of the housing structure at least in an upward manner. The housing cover has a multi-layered construction and includes a lower metal layer and an upper metal layer. The lower metal layer and the upper metal layer are mutually disposed so as to be substantially vertically spaced apart, define a cover space therebetween, and are fixedly interconnected at peripheries. A plastics core layer substantially fills the cover space and mechanically interconnects the two metal layers.

An object of the present invention is to provide: a laminate which is capable of satisfying two requirements, namely, weight reduction and fire resistance at the same time; an in-vehicle battery containing body; and a method for producing an in-vehicle battery containing body. In order to achieve the object, a laminate 5 according to the present invention includes at least a first layer 51 containing a thermoplastic or thermosetting resin and a second layer 52 containing an incombustible or flame-retardant nonwoven fabric. The first layer and the second layer form an integrally molded article in which at least part of the resin of the first layer melting to combine and integrated with the second layer. An in-vehicle battery containing body 1 includes containing bodies 2, 4 for containing an in-vehicle battery 3, and at least a portion of the containing bodies 2, 4 is formed by a laminate 5. At least two layers, namely a first layer 51 and a second layer 52, are laminated on each other, and then, integrally molding at the same time such that at least a portion of the resin of the first layer 51 is melted and combined with the second layer 52.

A solid-state polymer lithium battery pack and a preparation method therefor are provided. The lithium battery pack includes: single batteries (1), connecting sleeve members (2), electric cables (3), a battery box (4) and a pouring sealant, and has functions of power supply, power storage and multiple charging/discharging. The preparation method includes: connecting a plurality of single batteries in series by means of connecting sleeve members (2) to form combined batteries; connecting a plurality of combined batteries in series to form a lithium battery pack; and finally, assembling the lithium battery pack into a battery box (4), filling a pouring sealant inside the battery box by means of a sealant pouring process for fixing the single batteries (1) and internal electric cables (3), and discharging air in the battery box (4), so that a final solid-state polymer lithium battery pack is obtained.

A battery enclosure for a vehicle chassis comprising a base plate having an upper and lower surface and a plurality of edges; an external support structure with a flange portion on a lower surface thereof and disposed on an upper surface of the base plate to circumscribe the base plate edges; a battery tray with a flange portion extending from an upper surface thereof is disposed on an upper surface of the base plate. The battery tray includes a plurality of raised surface features on the upper surface outlining individual cells, each cell configured to receive at least one battery. A lid is disposed on the flange of the battery tray with the external support structure disposed below the battery tray flange, and extending around the battery tray edges.
