Abstract: 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.

Abstract: 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.
