Abstract
A hybrid 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, fuel cell, or flywheel. The second energy storage device provides intermittent energy bursts to satisfy the power requires of, for example, pulsed power communication devices. The first and second energy storage devices are coupled to a current controller to assure that pulse transients are not applied to the first energy storage device as a result of charging the second energy storage device.
