    Patent number: 6841971
    Abstract: A system for equalizing the voltages across first and second batteries coupled in series at a common terminal comprising a capacitive storage element, first and second inductive storage elements, first and second switch circuits, and a control unit. The capacitive storage element is coupled to first and second nodes. The first inductive storage element is coupled between the first node and the first battery. The second inductive storage element is coupled between the second node and the second battery. The first switch circuit is coupled between the first node and the common terminal. The second switch circuit is coupled between the second node and the common terminal. The control circuit operates the first and second switch circuits to control current flow to the first and second batteries.
