Abstract
A battery pack and a method of controlling the battery pack. The battery pack includes a battery cell and a capacitor connected in parallel to the battery pack. Accordingly, the battery power and the distance travelled by an electric transport device that requires an instantaneous high power output, such as an E-bike, may be increased.
