Abstract: 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.

Abstract: A battery pack includes battery cells arranged in a first direction, a wiring board collecting state information about the battery cells, and a sensing portion including an input port through which the state information about the battery cells is input, an output port coupled to the wiring board and through which the state information about the battery cells is output, and a connection portion between the input and output ports. The connection portion extends in a curved shape with portions spaced apart from each other in a second direction crossing the first direction. Damage or dielectric breakdown of a conductive line transmitting signals relating to the state information about the battery cells may be prevented, and accumulation of stress in the conductive line or an insulating film may be prevented, because the conductive line or the insulating film is flexibly deformed in response to swelling of the battery cells.
