A gasoline-powered Class-2 van was retrofittedfor hybrid operation by the addition of a traction motor,inverter,and an energy storage unit comprised of electrochemical capacitors(ECs).No batteries were *** system was evaluated using the Urban Dynamometer Driving Schedule(UDDS).Fuel mileage was improved 15-21%.Operational life is predicted to be 10～15 *** mileage depends on the power management strategy,which must be different from that used with a battery energy storage system.
