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. 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 first and second energy storage devices may be coupled to output electronics to condition the output of the devices prior to delivering it to the application device.
