Abstract

A power system for an electric vehicle, the power system comprising at least one power generating device selected from a group consisting of a solar panel, a wind turbine capable of producing electrical power, an auxiliary generator driven by an internal combustion engine, and a generator for producing electrical power mechanically connected to, and driven by the rotational force of an axle of a vehicle. The power system being further comprised of a charging device, a battery control device, at least one battery, a motor control device, an electric drive motor electrically connected to the motor control device, and a driver interface connected to the motor control device. The electric drive motor may be used to generate power through regenerative braking. The wind turbine may be raised outside the body of a vehicle while the vehicle is not in motion. The solar panel may be disposed outside the vehicle while remaining electrically connected to the charging device.
