Electric vehicle battery enclosures and methods of assembling electric vehicle battery enclosures involve a base portion to hold one or more batteries that provide motive power to an all-electric or hybrid electric vehicle. An electric vehicle battery enclosure includes a cover portion to mate with the base portion to enclose the one or more batteries, and a sealant to create a bond between the base portion and the cover portion around an entire perimeter of the enclosure and to seal the enclosure based on a uniform height of the sealant around the perimeter of the enclosure.

The invention relates to a casing for protecting at least one electric battery module (M), comprising at least one element (9) for thermal regulation of said at least one module (M) in which a heat-transfer fluid flows. According to the invention, the protective housing comprises at least one duct (10), for conveying heat-transfer fluid, that extends in at least one wall of the protective casing (B, 1, 2, 3, 4) and is in fluid connection with said at least one thermal regulation element (9).

A module layer and to a battery system made therefrom, which, as a device for supplying and storing electrical energy between two final end components, comprises a number of battery modules that are electrically connected to one another in series. Each module here consists of a number of elementary cells, which are generally lithium-ion batteries. The module layer is embodied as a structural unit, wherein the cells in the module layer are positioned next to one another in a tray, in an upright position on a base element of the tray, and are enclosed by an outer frame that is embodied as a heat sink and constitutes the rim of the tray, the outer frame has a seal, and the module layer has a section of a central shaft into which bus bars protrude, which produce a conductive connection with the cells of the respective module layer.

A battery module includes a battery assembly including a plurality of sub-packing units, the plurality of sub-packing units respectively including a cell housing, at least one battery cell accommodated in an internal space of the cell housing, and at least one vent hole disposed in the cell housing and connecting the internal space to an outside of the cell housing, and a flame blocking structure coupled to the battery assembly, and including an inlet hole connected to the vent hole, an inner chamber communicating with the inlet hole, an outlet hole communicating with the inner chamber and the outside, and at least one partition wall protruding into the inner chamber.

A frame for a battery pack includes: a first end beam; a second end beam; and one or more intermediate beams between the first end beam and the second end beam. Each of the beams is orientated along a first direction that is perpendicular to a virtual plane, and includes: a first plate having a first side, and a second side opposite to the first side of the first plate; a second plate having a first side, and a second side opposite to the first side of the second plate; and a coupling means slidably coupling the second side of the first plate to the second side of the second plate to inhibit any displacement of the first plate relative to the second plate, except for a shifting of the first plate relative to the second plate in or against the first direction.

A case, a battery, a power consuming device, and a method for assembling a case are provided. The case includes a first case body, an accommodating groove, a sealant, and a second case body. The first case body is provided with an opening. The accommodating groove is provided in a peripheral direction of the opening. The sealant is accommodated in the accommodating groove. The second case body is provided with a peripherally-arranged joint part. The joint part is configured to extend into the accommodating groove and be joined with the sealant when the second case body covers the opening, so as to form a sealed connection between the first case body and the second case body. The accommodating groove can limit the sealant, the sealant does not shift in the accommodating groove, and a sealing failure is less likely to occur, thus ensuring the sealing performance of the sealant.
