<p>A rechargeable battery pack comprises a cell pack comprising unit cells formed with rechargeable batteries; a protection circuit module; a temperature sensor attached to a unit cell having the fastest speed of temperature increase among the unit cells, and connected to the protection circuit module. A method includes a classifying step including selecting unit cells within a predetermined range of voltage-current characteristic and classifying the unit cells by a speed of temperature increase; a cell packing step connecting the unit cells, disposing a unit cell having the fastest speed of temperature increase to a position where a temperature sensor is connected and then connecting the classified unit cells to form a cell pack; a connecting step for installing a protection circuit module to a position where the temperature sensor is connected and then connecting the temperature sensor with the unit cell and the protection circuit module with the temperature sensor.</p> |
