The present disclosure provides a battery module, which comprises: a harness isolation board provided with a mounting groove; an output pole connection sheet; and a fixing assembly. The fixing assembly comprises: a connecting member placed in the mounting groove to be fixed on the harness isolation board; and a fastening member securely connected to the connecting member and fixing the output pole connection sheet. The connecting member and the fastening member are separately formed and securely connected together, the fastening member is fixed on the harness isolation board via the connecting member, thus the fixing manner between the connecting member and the harness isolation board is not related to the fastening member, and in turn it only needs to improve the structure of the connecting member and the harness isolation board to enhance the connecting strength and the anti-torque effect between the fixing assembly and the harness isolation board.

A battery cover including a main body, an opening/closing part provided on the main body, a flexible rib having a locking projection provided on the opening/closing part, an abutting rib provided on the main body, which has a locking recess to be engaged with the locking projection while the opening/closing part is opened to the main body, a contact portion that abuts on the locking projection and deflects the flexible rib when the opening/closing part is opened to the main body, and a flat portion provided on the contact portion, which abuts on the locking projection first when the opening/closing part is opened to the main body and extends in the direction orthogonal to the direction of force input when abutting on the locking projection.

A sealed battery includes a case, an internal terminal, an external terminal, and an insulating holder. The internal terminal of the sealed battery includes a collector connected to an electrode body, a shaft part exposed outside the case, and a crimping part that is provided in an upper end portion of the shaft part. The crimping part is formed by pressurizing and deforming an upper end portion of the shaft part such that the crimping part extends along an upper surface of the external terminal. Then, the external terminal arranged outside the case is configured so that a linear expansion coefficient on a side of the upper surface and a linear expansion coefficient on a side of a bottom surface in contact with the insulating holder are different from each other.

A battery pole terminal, having an annular section, which surrounds a cylindrical or conical receiving space at least in sections in a circumferential direction, the annular section having an interruption with respect to the circumferential direction with two opposite edges. A gripping section for a clamping mechanism is provided at each of the edges. Furthermore, the battery pole terminal has a clamping mechanism which acts on the gripping sections and can exert a clamping force on the edges, pushing the opposite edges toward each other. A force limiting mechanism is provided which, when a minimum distance between the edges is reached, prevents an increase in the clamping force on the gripping sections.

A battery pack that protects an internal configuration from external impact and effectively prevents internal short circuit is disclosed. The battery pack includes a plurality of can type secondary batteries arranged to be laid down in a horizontal direction; a bus bar at least partially formed of an electrically conductive material to electrically connect the plurality of can type secondary batteries; at least one module case with an empty space formed inside to accommodate the plurality of can type secondary batteries; and an insulating tube configured to surround an outer wall of the module case and having an outer surface on which a plurality of embossing structures with a part bulging in an outer direction are formed.

Battery parts having retaining and sealing features and associated assemblies and methods are disclosed herein. In one embodiment, a battery part includes a base portion that is configured to be embedded in battery container material of a corresponding battery container. The battery part and base portion include several torque resisting features and gripping features that resist torsional or twist loads that are applied to the battery part after it has been joined to the battery container. For example, the base portion can include several internal and external torque resisting features and gripping features that are configured to resist twisting or loosening of the battery part with reference to the battery container material, as well as prevent or inhibit fluid leakage from the battery container.
