Air-Powered Auxiliary EV Charging and Battery-Cooling System

An air-powered auxiliary battery charging and battery-cooling system for electric vehicles is disclosed. The system includes a forward-facing air intake assembly configured to capture ram-air during vehicle motion and direct the airflow through intake ducts toward impellers housed in impeller enclosures. The impellers rotate and drive generator modules that produce supplemental electrical energy, which is conditioned to charge the vehicle's battery pack. Air exiting the impeller housings is routed through transition ducts that reshape the airflow from a circular to a rectangular profile before entering a distribution duct positioned adjacent to the battery pack. One or more heat-transfer members are disposed within the distribution duct to diffuse the airflow across the battery surface to remove heat and improve thermal stability. The airflow is released through an exhaust duct oriented toward the rear of the vehicle.
