Abstract
A power tool/battery pack combination includes an electric motor, one or more electrochemical cells, and a capacitive element. The electric motor is connected in series to a first switch. The series combination of the electric motor and the first switch is connected to a first terminal and a second terminal. The one or more electrochemical cells are connected across a third terminal and a fourth terminal. The third terminal and the fourth terminal are coupled respectively to the first terminal and the second terminal. The one or more electrochemical cells supply power to the electric motor via the first switch. The capacitive element includes one or more capacitors. The capacitive element is connected across the third terminal and the fourth terminal. The capacitive element is capable of storing inductive energy generated by the one or more electrochemical cells.
