An assembly structure of a cover and a terminal for a power battery, including a cover and a terminal. The terminal includes a base and a post extending downwards from the base. The cover is provided with a mounting hole through which the cover is inserted against the terminal. A high-temperature resistant component is provided between the base and the cover, and a conductive block is riveted to a lower end of the terminal. A sealing member is provided between the conductive block and the cover. Different from the existing terminals, the present terminal is T-shaped. Therefore, current carrying area and capacity of the upper surface of the terminal are increased. Further, the riveting structure is provided at a bottom of the terminal, which can avoid the inaesthetic appearance of the terminal caused by soldering. The reliable assembly structure can avoid the terminal loosening and short circuit of the cell.

A battery pack includes: a connector holder that is fixed to an exterior case and has two main surfaces that include a first main surface exposed through an opening of the exterior case; a floating connector connected with a center of the connector holder in such a manner that the floating connector floats in such a manner that an orientation or a position of the floating connector is variable upward, downward, leftward, and rightward; a lead wire fixed to an inner surface of the floating connector, the lead wire extending through an inside of the exterior case, and the lead wire connecting floating connector with a circuit board; and a positioning buffer that pushes the floating connector, and positions the floating connector at a predetermined original state when an external force is not applied to the floating connector.

A top cap for a secondary battery includes a circumferential area which defines an outer circumferential surface of the top cap, a central area which defines a central portion of the top cap, a connection area which connects the circumferential area to the central area, and a protrusion area which protrudes downward from the circumferential area, the central area, or the connection area. The top cap is assembled with a battery case, an electrode assembly positioned therein, and a through-hole formation member to form a secondary battery, in which at least a portion of the protrusion area of the top cap is positioned within a through-hole of the through-hole formation member.

A mounting rack is described for a power electronics installation, including busbars for electrically connecting a plurality of assemblies, which busbars are arranged on the rear side of the mounting rack. A corresponding power electronics installation is also described.

A secondary battery including an electrode assembly; a first case that includes an electrode assembly accommodating space; and a second case that coupled to the first case, the second case facing the first case and having a convex-concave pattern.

Electrical feedthroughs for battery housings are presented. The electrical feedthroughs include a connector, a ceramic insulator, and a terminal. A first seal couples the connector to the ceramic insulator via a first braze alloy. A second seal couples the ceramic insulator to the terminal via a second braze alloy. The electrical feedthroughs can also include a spacer. A first seal couples the connector to the ceramic insulator; a second seal couples the ceramic insulator to the spacer; and the third seal couples the spacer to the terminal. The first seal, the second seal, and the third seal include, respectively, a first braze alloy, a second braze alloy, and a third braze alloy.

The present disclosure relates to a secondary battery. The secondary battery includes a cap assembly including a cap plate provided with an electrode lead-out hole, an electrode terminal covering the electrode lead-out hole, a sealing ring disposed between the cap plate and the electrode terminal, and a lower insulating member including a base portion and a protruding portion connected to each other, wherein the base portion is located at a lower side of the cap plate and the protruding portion is at least partially located in the electrode lead-out hole; a current collecting member including a body portion and an extending portion connected to each other, wherein the body portion is located below the base portion, and the extending portion extends into the electrode lead-out hole and is connected to the electrode terminal; and a support member disposed between the body portion and the base portion.

A battery includes: a casing that includes a plurality of exterior faces having outer faces facing mutually-different directions and has an arrangement concave part formed; a cell that is housed inside the casing; and a connector that includes a connection terminal connected to an electrode terminal of a connection apparatus and is arranged in the arrangement concave part, in which a face forming the arrangement concave part of the casing is formed as a concave part forming face, and the concave part forming face is present between the exterior faces and the connector.

A sealed battery of the present invention comprises: an electrode assembly having a multilayered structure in which a positive electrode, a negative electrode, and a separator are layered; and a first clip. The positive electrode has a positive-electrode current collection sheet and a positive-electrode active material layer; and the negative electrode has a negative-electrode current collection sheet and a negative-electrode active material layer. The electrode assembly has the following sections: a positive-electrode extended section which is a layered portion of the positive-electrode current collection sheet and extends from the multilayered structure; and a negative-electrode extended section which is a layered portion of the negative-electrode current collection sheet and extends from the multilayered structure. The first clip is provided in such a way that either one of the positive-electrode extended section and the negative-electrode extended section is sandwiched and fastened between the first plate section and the second plate section; and the first clip has a first gripping opening. The positive-electrode extended section or the negative-electrode extended section fastened by the first clip has a first fold portion formed by folding the current collection sheet by using an end of the first or second plate section at the first gripping opening as a fulcrum point.

A current interrupt apparatus and a flipping member thereof, a battery cover plate assembly, a cell, a battery module, a power battery, and an electric vehicle are provided. The flipping member is to be electrically connected to a score member, and can act under an effect of air pressure to break a score on the score member so as to cut off the electrical connection to the score member. A first connection region to be electrically connected to the score member and a second connection region to be electrically connected to an outer electrode terminal of a battery are formed on the flipping member. A deformation cushion region is further formed on the flipping member. The deformation cushion region is disposed between the first connection region and the second connection region and around the first connection region.
