摘要：	The NASA John H. Glenn Research Center initiated baseline testing of the EV Global E-Bike with asymmetric ultracapacitors as a way to reduce pollution in urban areas, reduce fossil fuel consumption and reduce operating costs for transportation systems. The E-Bike provides an inexpensive approach to advance the state of the art in hybrid technology in a practical application. The project transfers space technology to terrestrial use via nontraditional partners and provides power system data valuable for future space applications. The work was done under the Hybrid Power Management (HPM) Program, which includes the Hybrid Electric Transit Bus (HETB). The E-Bike is a state of the art, ground up, hybrid electric bicycle. Unique features of the vehicle's power system include the use of an efficient, 400 watt, electric hub motor and a 7-speed derailleur system that permits operation as fully electric, fully pedal, or a combination of the two. Other innovative features, such as regenerative braking through ultracapacitor energy storage, are planned. Regenerative braking recovers much of the kinetic energy of the vehicle during deceleration. The E-bike has previously been tested with the standard battery energy storage system. a symmetric ultracapacitor energy storage system, and a combination battery and symmetric ultracapacitor energy storage system. The focus of this report is the test results of the E-bike with asymmetric ultracapacitor energy storage and comparison to the other energy storage systems. The report concludes that the E-Bike provides excellent performance and that the implementation of asymmetric ultracapacitors in the power system can provide significant performance improvements.
