The present invention relates to a battery module. The battery module according to the present invention includes a housing having an internal accommodation space; and a plurality of battery cells disposed in the internal accommodation space, in which the housing includes a weld joint in which a first base material of a first aluminum-based alloy and a second base material of a second aluminum-based alloy are welded, and at least a partial region of a bead surface of the weld joint is located inward with respect to a reference plane, with an imaginary plane, which connects an outer surface of the first base material and an outer surface of the second base material in contact with the weld joint, as the reference plane.

The present application provides an insulating composite plate comprising: an upper plate layer, a lower plate layer, and a middle plate layer, wherein the upper plate layer and the lower plate layer are made of a thermoplastic material; the middle plate layer is located between the upper plate layer and the lower plate layer, the middle plate layer being a metal mesh; the upper surface of the middle plate layer and the lower surface of the upper plate layer are bonded together, and the lower surface of the middle plate layer and the upper surface of the lower plate layer are bonded together. An insulating composite plate provided by this application has good insulation properties and can shield electromagnetic interference.

The present invention provides a battery module case for an electric vehicle, wherein an electric vehicle battery provided to be utilized in an electric vehicle is accommodated inside the battery module case to improve assemblability. The battery module case for an electric vehicle is characterized by comprising: a case part which is formed by extrusion-molding an aluminum material, has a cavity formed in an inner profile corresponding to the outer profile of the battery for an electric vehicle, and is open in at least one end in the longitudinal direction, wherein a press-fit protrusion is formed along the edge of the open end; and at least one cover part which is formed by die-casting an aluminum material and provided so as to be coupled to the open end of the case part, and in which an extension portion is integrally formed to extend and protrude toward the case part from the edge thereof, at a position corresponding to the press-fit protrusion, so as to be press-fit on the edge of the press-fit protrusion, and both-side contacting grooves surrounding and closely contacting both sides of the press-fit protrusion are recessed in an end section of the extension portion.

Exemplary battery pack designs for use in electrified vehicles may include an enclosure assembly that houses one or more battery internal components (e.g., battery arrays, battery electronic components, or both). A tear-away service panel may be positioned within a wall of the enclosure assembly. The service panel may be removed from the enclosure assembly to access one of the battery internal components requiring service and may be subsequently replaced with a replacement service panel. The replacement service panel may be part of a battery pack resealing kit.

A charging device includes a base and a platform that extends upward from the base. The base and platform may each be configured with wireless charging surfaces to enable wireless charging of a computing device upon contact. The base includes a recess in front of where the platform extends to provide support to a computing device, such as a smartphone. The base's surface may gradually rise until reaching the recess to provide further support to the smartphone and thereby prevent the smartphone from sliding down. The charging device includes female receptacles to enable charging adapters to connect to the charging device, thereby increasing the number of accessories charged with the charging device. Charging adapters can include a laterally extending platform on which, for example, a smartwatch can rest, or a charging shaft that includes a series of electrical contacts for charging external battery devices.
