A battery pack includes a battery cell, an input/output terminal to/from which a charging/discharging current of the battery cell is to be inputted/outputted, and a connector detachably connected to the input/output terminal, and the input/output terminal includes a first hollow conductive member protruding in a first direction and a second hollow conductive member protruding to surround an outer periphery of the first hollow conductive member, the connector includes a central guide protruding in a second direction opposite to the first direction and a third hollow conductive member protruding to surround the outer periphery of the central guide, the central guide is fitted into a hollow portion of the first hollow conductive member, and the third hollow conductive member is fitted into a space between the first and second hollow conductive members and is electrically connected to the first and second hollow conductive members by an elastic connection member.

Battery pack

A battery pack is provided. The battery pack includes a battery cell, an input/output terminal electrically connected to the battery cell, the input/output terminal including an upper end portion and a lower end portion in a first direction, and a charge/discharge current of the battery cell being input and output through the input/output terminal, a connector electrically coupled to the input/output terminal, the connector including a fastening portion coupled to the input/output terminal at a fastened height between the upper end portion and the lower end portion of the input/output terminal, and a slider which is slidable in a second direction crossing the first direction, between a first position, at which the slider covers the fastening portion, and a second position, at which the slider exposes the fastening portion, and a fastening member electrically coupling the input/output terminal and the connector to each other.

A battery pack includes: a plurality of parallel modules arranged in an arrangement direction; and a bus bar through which different polarities of parallel modules of the plurality of parallel modules that are not adjacent to each other in the arrangement direction are connected in series to each other. In the battery pack, output terminals having different polarities are provided at adjacent positions. Therefore, the battery pack may be easily electrically connected to a set device. In addition, since the electrical paths of the output terminals are shortened, the battery pack may have improved electrical output power and spatial efficiency by a simple structure, and may be durable against vibrations and shocks.

A battery module includes a plurality of battery cells aligned in a first direction and a housing portion fixing the plurality of battery cells, wherein central parts of the plurality of battery cell are concave, and wherein first adhesive members are between adjacent battery cells.

Battery module

A battery pack including a plurality of battery cells; a housing accommodating the plurality of battery cells; a connector coupled to the housing, at least a portion of the connector being exposed outside of the housing; and a sealing member coupled to the connector, the sealing member surrounding the exposed portion of the connector.

An embodiment of the invention relates to a battery pack having a strength-reinforced housing that accommodates a plurality of battery cells. In one embodiment, the battery pack includes one or more battery cells, a housing accommodating the one or more battery cells, and a reinforcement portion formed in the housing. The housing has a bottom portion and three sidewalls upwardly extending from three-sided perimeters of the bottom portion. The reinforcement portion surrounds surfaces of the three sidewalls.
