The current status of a program to develop and evaluate a regenerative flywheel energy storage system is described. The system has been designed for a battery/flywheel electric vehicle in the 3000 pound class. Planned laboratory tests will simulate this electric vehicle operating over the SAE J227a Schedule D driving cycle. The range improvement attributed to the use of the flywheel will be established. The flywheel energy storage system will consist of a solid rotor, synchronous inductor-type flywheel drive machine electrically coupled to a dc battery electric propulsion system through a load commutated inverter. The motor/alternator unit is coupled mechanically to a small steel flywheel which regenerates the vehicle's braking energy. The laboratory simulation of the battery/flywheel propulsion system will include a 108 V lead--acid battery bank, a separately excited dc propulsion motor coupled to a flywheel which simulates the vehicle's inertia, and the flywheel energy storage system comprised of the motor/flywheel unit, the load commutated inverter and its control.
