A battery pack includes an antenna attached to a battery cell, a sensor configured to sense an energy level induced in the antenna, a controller configured to determine, according to a sensed signal of the sensor, whether the energy level is a first energy level for wireless charging or is a second energy level for near field communication, and a switch connecting the antenna to a battery charger or a near field communication circuit according to a control signal of the controller.

Battery pack with wireless charging and near field communication functions

In a rechargeable battery, a case is combined with an upper surface of a bare cell by being fixed to a lead plate electrically coupling a protection circuit board of a protection circuit module to the bare cell. Alternatively, the case is combined with the bare cell by being fixed to the protection circuit board so as not to be separated from the bare cell, thereby improving the reliability of the products.
