Abstract

A supplemental power supply system for supplying power to an electric engine. The system includes a generator for generating power, a charger coupled to the generator, wherein the charger provides charging power to a battery; and a drive module coupled to the generator, wherein the drive module provides power to an electric drive motor and wherein the battery simultaneously provides power to the electric drive motor.

Claims

1. A supplemental power supply system for supplying power to an electric drive motor, comprising:

a generator configured to interface with an engine, wherein the engine turns the generator, the engine including a starter, the starter comprising a ring gear having an opening on one end thereof and wherein teeth are formed on an interior surface of the ring gear, the opening sized to receive a cooperating gear of a starter bendix, whereby the rotation of the starter bendix causes the ring gear to rotate in the same direction;

a charger coupled to the generator, wherein the charger provides charging power to a battery; and

a drive module coupled to the generator, wherein the drive module provides power to the electric drive motor and wherein the battery simultaneously provides power to the electric drive motor.

2. The system of claim 1 wherein the control switch is connected to a starter, wherein the starter is configured to provide control signals and wherein the starter is further configured to start the engine.

3. A hybrid power supply for a vehicle, comprising:

an engine coupled to a generator, the engine for turning the generator, the engine comprising a starter, the starter comprising a ring gear having an opening on one end thereof and wherein teeth are formed on an interior surface of the ring gear, the opening sized to receive a cooperating gear of a starter bendix, whereby the rotation of the starter bendix causes the ring gear to rotate in the same direction;

a battery coupled to an electric drive motor;

a charger coupled to the generator, wherein the charger provides charging current to the battery;

a drive module coupled to the generator, wherein the drive module provides current to an electric drive motor and wherein the battery simultaneously provides current to the electric drive motor.
