A battery pack includes: a plurality of unit cells arranged side by side in a first direction and each comprising a first terminal and a second terminal to improve the durability and safety of the battery pack; a protection circuit module disposed on the plurality of unit cells; and a temperature element unit disposed on the plurality of unit cells in the first direction and comprising a first temperature element, a second temperature element, a first plate connecting the first temperature element and the second temperature element, and a second plate having an end electrically connected to the protection circuit module and another end electrically connected to the first plate disposed between the first temperature element and the second temperature element.

Battery pack

Provided is a battery pack, which can be prevented from being released from a label adhered to a frame or a battery cell due to distortion applied to the battery pack, thereby preventing noises from being generated during movement of an adhered surface of the label. A battery pack is also provided, which may prevent electrostatic discharge (ESD). The battery pack includes a battery cell, a protective circuit module (PCM) electrically connected to the battery cell, a frame accommodating the battery cell and the PCM, and a label adhered to the battery cell, the PCM and the frame while surrounding the same. A release sheet is attached to a region of the label surrounding the PCM.

Secondary battery with protection circuit module with label and release sheet

In a battery pack, a component for attaching a secondary protection device to a bare cell may be omitted to reduce manufacturing costs and improve productivity. The battery pack includes a bare cell, a flexible printed circuit board in which at least one portion thereof contacts the bare cell, the flexible printed circuit board being electrically coupled to the bare cell through a lead pattern surrounded by an insulation cover, a secondary protection device on the flexible printed circuit board, the secondary protection device being electrically coupled to the flexible printed circuit board through the lead pattern, and a protective circuit module electrically coupled to the flexible printed circuit board through the lead pattern.
