A rechargeable battery module includes: a bottom plate supporting a plurality of cells and having mounting holes at both ends; a pair of side plates coupled to both sides of the bottom plate; a pair of end plates coupled to the bottom plate and the side plates at both sides; a mounting plate coupled to the bottom plate and the pair of side plates between the pair of end plates, the mounting plate having a through installation hole through which a mount member extends therethrough from the outside thereof to fasten the rechargeable battery module to a platform of an electric vehicle or a rack of an energy storage system; a top cover coupled to the side plates, the end plates, and the mounting plate; and a final terminal connected to a bus bar connecting electrode terminals of the cells.

A battery pack includes: a plurality of battery cells arranged into rows adjacent to each other, adjacent rows of battery cells being alternately shifted to front positions or rear positions in a row direction; busbars arranged to form a parallel group of battery cells by connecting a group of battery cells to each other in parallel, and connecting adjacent parallel groups to each other in series, the busbars including a body portion extending in a zigzag shape in a column direction and a first and second branch portion extending in the row direction from the body portion toward different parallel groups; and expansion pieces protruding from the body portion of the busbar to external positions outside the plurality of battery cells in the row direction or the column direction.

A battery module includes a plurality of battery units arranged in a first direction and each including a plurality of battery cells arranged in a second direction perpendicular to the first direction, and two holders respectively located at two ends of the plurality of battery units in a third direction perpendicular to the second direction and the first direction. Each of the holders includes a main body portion. A plurality of guide portions are provided on a side of the main body portion close to the plurality of battery units, and are arranged corresponding to the plurality of battery units. The guide portions extend toward the plurality of battery units in the third direction, and are configured to provide guidance for movement of the corresponding battery cells. Extension lengths of the plurality of guide portions gradually decrease in the first direction.

A traction battery of a motor vehicle is disclosed. The traction battery includes a housing having a housing pot and a lid closing the housing pot. A plurality of components to be cooled are arranged in the housing. A cooling device having at least one cooling channel is arranged within the housing and connected to the components to be cooled in a heat-transferring manner. At least one insert is provided. The components to be cooled lie against the at least one insert in a heat-transferring manner.

A battery receptacle for a rail vehicle and a rail vehicle with a battery receptacle. The battery receptacle has a volume form which deviates from a cuboidal form. The battery receptacle has connection elements that are designed such that the battery receptacle can be pivotally connected to an associated battery box of the rail vehicle so that when the battery receptacle is rotated about an axis it can be rotated into the battery box or rotated out of the battery box.

The invention relates to a battery (1) for electric bicycles comprising a total number N of cells (2) distributed in an optimized way, a management system (4) and at least one connector (5). The battery (1) is characterized in that it comprises a distribution with at least one additional semi-block (3b), created by at least one cell (2) separated from a block (3) or semi-block (3a) at one end (1a) of the battery (1), creating at least two spaces (6, 7). The previous space (6) is located in the semi-block (3a) of the end (1a) of the battery (1) created by the absence of at least one cell (2) and intended to connect the management system (4), and the new space (7) is in the additional semi-block (3b) created by the absence of at least a number n−1 of cells (2) and destined to house the connector (5).
