## Title
Electric vehicle range extender charging

## Abstract

In an electric vehicle having a primary battery powered source of energy with a primary electric motor driven and connected to one or more ground engagement wheels of the electric vehicle, has a device called a sprocket used for collecting energy form the inner rim edge of the rear wheel of the electric vehicle. This sprocket mechanism device collects this energy then transfers that energy to alternators one and two on its mounted framework in the trunk compartment by way of a chain. The two alternators with its sitting pilot voltages, then transfer it by required electrically conductive cables sending energy to the battery bank source thus completing the on board charging system cycle.

BACKGROUND OF THE INVENTION
The present invention relates to an auxiliary power transfer device for an electric vehicle and more particularly to an auxiliary mounted sprocket source device powered by one or more wheels of an electric vehicle powered solely by batteries are well known and the electric vehicle whose drive systems are powered solely by battery sources are well known. Combining the two sources of energy to drive an electric vehicle has heretofore been deemed practical.
BRIEF SUMMARY OF THE INVENTION
In accordance with the invention, therefore, there is provided an electric vehicle comprising a primary electric motor powered by a primary battery bank source with electrical energy. The primary motor being driven and connected to one or more plurality of ground engagement wheels mounted on the electric vehicle; an auxiliary device driven and connected to one or more of the ground engagement wheels; a sprocket energy collecting device mounted on the electric vehicle for connecting to the wheels rotating energy; the sprocket energy collecting device included as an energy supply mechanism routing energy collected from the rear wheel inner rim edge.
The energy supply device comprises a battery bank source and an electrically conductive cable connected to the primary motor collecting device and delivering energy to one or more of the ground engagement wheels.
The energy supply device further comprise connections between the two alternator devices and receives energy from the wheel driven sprocket sending an electrically conductive cable to the battery bank source.
The primary battery bank source and the primary electric vehicle motor devices will alternately be driven and or connected electrically to a common ground engagement wheel.
The primary electric vehicle motor device typically includes an energy regenerator connected to the battery bank source while the energy regenerator is being driven and connected to the wheel which is driven and connected to a sprocket mechanism device mounted on the inner rim edge of the rear wheel and operating to regenerate energy for storage and usage in the battery bank source in response to the rotation of the connected and driven wheel. A modular gear box on the other hand consisting of several hard plastic and or metal gears is known as being capable of replacing the sprocket mechanism devices for space and strength are well known.
