碩士 === 國立臺北科技大學 === 車輛工程系所 === 104 === In view of pure electric vehicles in the world today is becoming increasingly popular, as well as an extension the problem of battery life out of the poor and insufficient motor power, etc. Therefore, this study tried to take advantage of a commercially available Green Trans e-moving Super to do the transformation from the original motor connected to the wheels directly modified the two-speed transmission system, and hope that concept like the motorcycle, to solve the bottleneck for the electric scooter. The study also research the effect with regenerative braking to the electric scooter. In this two gear shifting mechanism, how can we use of regenerative braking system more efficient, to improve battery life and the other problem; this study focuses on improvements the regenerative braking system’s logic, with written program by the embedded systems, plus on providing additional regenerative braking when taxiing, do the experiments tested in different environments and speed. The results show that the two-speed transmission each has 20% promotion at first gear and second gear. Extra glide at high speed can be backfilled 0.210 Cullen ~ 5.102 Cullen of charge, and with the new logic of a more comprehensive use of the regenerative braking function overall driving 30km/hr conditions in the laboratory with the full power to the rated voltage of about 1268.53 Cullen can enhance the power, the road is about 1283.91 Cullen.
