초록 ▼

The present invention relates to a method and system for a more efficient and dynamic waste heat recovery system in an automobile. The present invention includes a heat exchanger connected to a generator. The heat exchanger includes variable pitch impellers attached to and rotating a shaft. The pitch of the impellers can be dynamically varied and the impellers can also be staggered. The generator includes a rotor connected to the shaft. The rotor rotates within a stator when the shaft rotates. The stator includes windings with different thicknesses and different turn ratios allowing for generation of different energy levels by each of the windings. Each of the windings can be dynamically activated. The pitch of the impellers can be dynamically altered and the windings can be dynamically activated depending on energy requirements of an energy storage unit and/or accessories in the automobile.
