NOVELTY - Apparatus, which is installed in an electrically driven vehicle, contains a ram air driven variable pitch turbine electric generator (12) to provide electric energy to be stored in a battery energy storage device to power electrical components of the vehicle and a power management unit (15) to comprise a computer controlled battery charging system that will adjust the turbine blade angles and electrically de-couple the battery charge resistance load from the generator to minimize drag caused by the turbine and maintain ram air generated energy flow.    USE - The apparatus is used for converting ram air energy into electric energy to recharge the energy storage devices of the vehicle while minimizing the apparatus caused drag effect on the vehicle, thus extending the driving range of the vehicle between external charging.    ADVANTAGE - The apparatus provides a reliable means to harvest efficiently the ram air energy generated by a moving electric vehicle to extend the driving range of the vehicle and reduce the frequency of required external re-charging of the vehicle energy storage devices.    DETAILED DESCRIPTION - Apparatus, which is installed in an electrically driven vehicle, contains a ram air driven variable pitch turbine electric generator (12) to provide electric energy to be stored in a battery energy storage device to power electrical components of the vehicle and a power management unit (15) to comprise a computer controlled battery charging system that will adjust the turbine blade angles and electrically de-couple the battery charge resistance load from the generator to minimize drag caused by the turbine and maintain ram air generated energy flow, caused by the vehicle motion, to the battery that compensates for the vehicle drive energy expended to overcome the turbine caused drag in varying conditions of the vehicle speed and the battery charge level. It contains: (a) a ram air driven electric generator driven by a variable pitch wind turbine mechanically coupled to and driving the rotor of the generator and mounted in an assembly which is positioned within the engine compartment of the vehicle; (b) a battery energy storage device providing primary operational power to the vehicle; (c) an ultra capacitor auxiliary device electrically connected to the generator and the battery and controlled by the computer that will de-couple the battery electrical resistance load from the generator to minimize electrical torque load on the turbine generator and reduce drag caused by the turbine; (d) an air intake, outlet, and ductwork in the engine compartment to direct ram air flow created by vehicle motion to impinge blades of the turbine and cause the turbine and the generator rotor to rotate and cause current to flow in the generator and to discharge the air flow to ambient space after it passes through the turbine blades; (e) the blades of the turbine are variable, under the charging system computer control, in angular position relative to the direction of ram air flow to adjust the blade surface area exposed to ram air force at varying speeds of the vehicle and minimize the turbine caused drag; and (f) the generator us electrically connected by the computer controlled charging system to charge the battery energy storage device and the ultra capacitor and power electrical components of the vehicle.
