Abstract
A regenerative braking system for an electric vehicle having front and rear wheels, and includes a drive wheel, an actuating device, a regenerative braking control circuit, and a power electronics circuit. The regenerative braking control circuit includes a potentiometer ir transducer, a process sensor, and a microprocessor. The system applies a regenerative braking torque to the drive wheel when the rider commands regenerative braking, and the process sensors signal a drive wheel velocity greater than zero. The present invention also relates to a throttle for actuating regenerative braking and reversing feature.
