Abstract
An energy storage system (10) including a first energy storage device (12), such as a secondary or rechargeable battery, and a second energy storage device (14), such as an electrochemical capacitor. The electrochemical capacitor provides intermittent energy bursts to satisfy the power requires of, for example, pulsed power communication devices. Such devices typically require power pulses in excess of those which conventional battery cells can easily provide for numerous cycles. The system (10) further includes circuitry (16) for coupling the capacitor (14) to a load in response to changes in the battery (12).
