電動アシスト自転車の一充電当たりの走行距離に対するペダリングの影響

抄録

Travel distance per charge is one of the important elements of electric power assisted bicycles. General method of measuring travel distance per charge is “BAA standard” method. However, in this method, measurement variation caused by difference of riders occurs. To reduce the variation, automatic measurement of travel distance per charge is needed. For realization of automatic measurement, we have measured electric power assisted bicycles by using chassis dynamometer and pedal sensors. In this study, the influence of pedaling for travel distance per charge of three electric power assisted bicycles was measured. The results of measurement showed that crank input torque affected the travel distance and maximum measurement variation caused by three riders was 2 km. Moreover, it was possible that maximum measurement variation was 3km.
