Electrochemical capacitor (ultracapacitor) technology for electric vehicles is reviewed. Data is presented for single cell and bipolar devices showing energy densities of 1-2 W.h/kg for IV, aqueous electrolyte devices and 5-7 W.h/kg for 3 V, organic electrolyte devices. Tests have been performed on the devices at constant powers up to 3 kW/kg. Barriers to the availability of these devices in quantities and costs suitable for testing are discussed as well as the need for interface electronics between the capacitor and the battery if the capacitor is to satisfactorily load level the battery.
