［Abstract］

　A development survey of components for energy regeneration system was carried out, while the regenerative energy in urban driving of passenger cars are calculated. Next, the maximization of kinetic energy regeneration by super capacitor and storage battery was examined using a motor bench tester and a charge-discharge tester. And, the detailed evaluation method for energy transfer in hybrid electric system was considered. Based on those results, suppression effects of carbon dioxide (CO2) discharge by introducing high-efficient automobile into urban traffic were predicted.
