Abstract
A battery pack including a heat radiation structure of a protection circuit module (PCM) using a heat radiation tape, wherein the heat radiation tape made of a material having heat conductivity is provided, and heat generated from the protection circuit module (PCM) is dispersively emitted based on the heat radiation tape wrapping the protection circuit module (PCM) in a “” shape to form a contact region at each of a side surface of a battery cell, a region between the protection circuit module (PCM) and the cell terrace part, and an upper portion of the protection circuit module (PCM).
Claims14
A battery pack comprising:
- battery cell including a cell terrace part extending upward on one side surface thereof, and the battery cell having a pair of electrode leads protruding outward through the cell terrace part;
- a protection circuit module (PCM) including two field effect transistors (FETS) disposed on each of upper and lower surfaces thereof, and the PCM being installed on the cell terrace part;
- a heat radiation tape attached while wrapping the protection circuit module (PCM) in a “” shape to form a contact region at each of a side surface of the battery cell, a region between the protection circuit module (PCM) and the cell terrace part, and an upper portion of the protection circuit module (PCM);
- and
- an upper tape to cover the upper portion of the protection circuit module (PCM) wrapped by the heat radiation tape.
A method for manufacturing a battery pack including a structure which radiates heat generated from a field effect transistor (FET) installed in a protection circuit module (PCM), the method comprising:
- a protection circuit module installation operation of installing the protection circuit module (PCM) on a cell terrace part of a battery cell by using a heat radiation tape having a “” shape to form a contact region at each of a side surface of the battery cell, a region between the protection circuit module (PCM) and the cell terrace part extending upward on one side surface of the battery cell, and the upper portion of the protection circuit module (PCM);
- a side surface covering operation of covering both side surfaces of the battery cell by attaching a side surface tape to each of both side surfaces of the battery cell;
- an upper and lower portion covering operation of attaching upper and lower tapes to upper and lower portions of the battery cell, respectively, to cover the upper and lower portions of the battery cell;
- and
- a front surface covering operation of attaching a front surface tape to a front surface of the battery cell to cover the front surface of the battery cell.
