A hybrid system design resulting from an investigation of battery-flywheel power systems for automobiles is presented. Topics include: (1) flywheel design, including sizing and safety; (2) power transmission design with an electromechanical transmission, traction motor, and flywheel motor; (3) control system design; and (4) performance calculations. Using a simplified mathematical model, a comparison is made between the hybrid performance characteristics and those of an all-battery electric vehicle. The hybrid design includes regenerative braking and flywheel relief of the drain rate. (PMA)
