Ultracapacitor technologies are reviewed with the emphasis on carbon-based devices using organic electrolytes. Such devices have cell voltages of 2.5 - 3 V. The energy density of commercially available large device (1200 - 2600 F) have usable energy densities of 3 - 4 Wh/kg with pulse power capability of 3 - 4 kW/kg. A small (3 V, 47 F) carbon-based laboratory prototype device has an energy density of 8.5 Wh/kg with a pulse power density of greater than 10 kW/kg. The conceptual design of ultracapacitor modules and energy storage units for vehicle applications indicated that the commercially available devices could be used effectively for engine starting to assist batteries in passenger cars and large class 8 trucks and as the power assist energy storage unit for hybrid-electric drivelines for passenger cars and transit buses.
