This application relates to a battery pack. In one aspect, the battery pack includes at least one battery cell, a heat transfer piece arranged on the battery cell at a position spaced apart from a charge-discharge path, and a circuit board including a lead portion coupled to the heat transfer piece and a main body connected to the lead portion. The circuit board is configured to acquire temperature information from the at least one battery cell. The battery pack further includes a temperature sensor arranged on the lead portion, a moisture-proof layer provided on the temperature sensor and configured to block penetration of external substances onto the temperature sensor, and an anti-shock layer provided on the moisture-proof layer and configured to absorb external shock. The battery pack is configured to accurately detect the temperature of the at least one battery cell and has a temperature sensing structure improved for reliably protecting the temperature sensor.

Battery pack

This application relates to a battery pack including a battery cell, a circuit board configured to collect state information about the battery cell, and a connection line configured to transmit the state information about the battery cell to the circuit board and including a link line and a board connection pad. The link line extends from a side of the battery cell toward the circuit board, and the board connection pad extends from a first end portion, to which the link line is connected, and is coupled to the circuit board while facing the circuit board. The board connection pad includes outer soldering portions formed in an outer region of the board connection pad and concave toward the outside of the board connection pad and a gas discharge hole formed in a closed loop shape in an inner region of the board connection pad.

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.

A battery pack includes: a plurality of battery cells; a battery management system to acquire state information and control charge-discharge operations; a wiring board through which the state information is transmitted to the battery management system, the wiring board including conductive lines for transmitting different electrical signals; and a connector including a connector terminal coupled to the conductive lines and a connector housing accommodating the connector terminal, the connector being coupled to a mating connector of the battery management system, wherein the connector terminal includes a bottom plate accommodating the conductive lines, and barrels protruding upward from the bottom plate and configured to be compressed onto the conductive lines while surrounding the conductive lines, and first and second embossments on the bottom plate and the barrels of the connector terminal, the first and second embossments protruding toward the conductive lines.

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 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.
