REGENERATIVE FLYWHEEL ENERGY STORAGE SYSTEM VolumeⅠ: Executive Summary

摘要

This report describes the development, fabrication, and test of a re¬generative flywheel energy storage and recovery system for a battery/fly¬wheel electric vehicle of the 3000-pound class. The vehicle propulsion system was simulated on a digital computer in order to determine the opti¬mum system operating strategies and to establish a calculated range improve¬ment over a nonregenerative, all-electric vehicle. Fabrication of the inductor motor, the flywheel, the power conditioner, and the system control are de¬scribed. Test results of the system operating over the SAE J227a Schedule D driving cycle are given and are compared to the calculated value,nThe flywheel energy storage system consists of a solid rotor, synchro¬nous, inductor-type, flywheel drive machine electrically coupled to a d-c battery electric propulsion system through a load-commutated inverter.
