Abstract
A vehicle having an electric hybrid power system is provided. The vehicle includes an electric motor drivably connected to one or more ground engaging wheels. A battery pack stores electricity to power the electric motor. An engine is drivably connected to the wheels with an alternator connected to the engine for recharging an accessory battery. The engine is located near the end of the vehicle opposite the end where the electric motor is located and the two motors are joined with a light-weight small-diameter drive shaft. The alternator has at least a voltage output range of between approximately the standard output voltage of the accessory battery and the standard output voltage of the battery pack. In accordance with the present invention, a mechanism for electrically connecting the alternator to the battery pack is provided such that the alternator alternatively recharges both the battery pack and the accessory battery.
