Design and development of a zero-emission scooter for Taiwan

A prototype zero-emission scooter (ZES) has been developed to solve air-pollution problems in the large cities of Taiwan. The design features of the ZES are described; these include battery, motor/driver, transmission systems, and body-chassis structure. The driving range of the prototype ZES in urban areas is about 40 km per single charge. Its maximum speed is over 50 km h−1, and it can accelerate to 30 m in less than 5 s. A future programme of field trials is also discussed.
