Electric hybrid vehicle
First Claim
1. A vehicle comprising:
- an electric motor drivably connected to at least one ground engaging drive wheel, the electric motor selectively having a function of rotating the drive wheel;
a battery being electrically connected to the electric motor, the battery selectively powering the electric motor, the battery selectively being charged by the electric motor;
a liquid fueled engine drivably connected to at least one ground engaging drive wheel, the liquid fueled engine selectively having a function of rotating the drive wheel;
an accessory battery electrically connected to vehicle accessories;
a recharger recharging the accessory battery and the battery, and the recharger receiving power from the liquid fueled engine;
a voltage controller altering the voltage output of the recharger; and
a switch changing the output of the recharger between the accessory battery and the battery, the switch directing the altered voltage away from the accessory battery and to the battery when the recharger has substantially charged the accessory battery.

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 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.

13. A vehicle comprising:
-
an electric motor drivably connected to at least one ground engaging drive wheel;
an electrical store electrically connected to the electric motor;
a liquid powered engine being connected to a drive wheel and generating electrical power;
an accessory electrical store providing power to vehicle accessories;
a recharger selectively recharging the accessory electrical store and the electrical store with a voltage output, and the recharger receiving power from the liquid powered engine;
a voltage controller altering the voltage output of the recharger, the voltage controller providing a higher voltage output to the electrical store and a lower voltage output to the accessory electrical store; and
a switch changing the voltage output of the recharger between the accessory electrical store and the electrical store, the switch directing a portion of the voltage output away from the accessory electrical store and to the electrical store when the accessory electrical store has been substantially charged. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
