Patent attributes
A battery pack includes an assembled battery, a battery case, a first temperature sensor and a second temperature sensor. The assembled battery has three or more battery cells electrically connected in series with each other. The battery case has the assembled battery received therein so that the assembled battery is partially exposed to outside of the battery case. The first temperature sensor is provided to detect the temperature of a most-exposed one of the three or more battery cells. The most-exposed battery cell has a maximum exposed area to the outside of the battery case among all of the three or more battery cells. The second temperature sensor is provided to detect the temperature of a least-exposed one of the three or more battery cells. The least-exposed battery cell has a minimum exposed area to the outside of the battery case among all of the three or more battery cells.
