Not only ICEV user but also EV users have interest in eco-driving. So, in this study, quantitative evaluation of eco-driving effect for EV was conducted using chassis dynamometer with new developed “Eco-driving test mode”. They were extracted from seventy two real-world driving data collected at the Eco-driving test-ride event. And they had four speed patterns which had same travel distance of 5.2 km and wide range of kinematic running energy. Three ICEVs, one HEV and two EVs were tested. The results showed that good linear relationships were found between kinematic running energy and fuel consumption rate for all 6 tested vehicles. Thus, eco-driving with low kinematic running energy by observing speed limit and constant speed was effective to not only ICE but also HEV and EV. The eco-driving effects from averaged drive as usual to averaged eco-driving in the eco-driving test-ride were estimated. And the effects of 660cc CTV ICEV, 1,300cc CVT ICEV, 1,800cc 4AT ICEV, 1,500cc HEV, EV type A and EV type B were 12.0%, 12.2%, 10.9%, 12.6%, 18.4% and 11.7% respectively. And the results indicated that EV had higher potential of eco-driving effect than ICEV if EV could maintain high energy conversion efficiency with various driving situations.
