Hammerslag, J G; Hammerslag, G R

This patent describes an electric vehicle drive system, comprising: a vehicle drive wheel, a reversible electric motor-brake connected with the wheel, a battery source of stored electrical energy in circuit with the motor, controller means in the circuit, a motor-generator in circuit with the controller means, a flywheel connected in drive relation with the controller means, accelerator and brake means in circuit with the controller means. The controller means is operable to control current flow between the battery source and the motor generator and the motor-brake to limit the current supplied to the motor-brake from the battery source in response to the current demand to drive the drive wheel and to supply current from the motor-generator to the drive wheel. A mounting means supports the flywheel for angular movement on an axis transverse to the axis of rotation of the flywheel, the mounting means supporting the flywheel on a horizontal axis and being angularly moveable on a vertical axis.
