Abstract: An air-cooled battery cooling system for an air mobility vehicle may ensure the cooling performance for batteries using air flows during the flight of the air mobility vehicle, since the cooling of the batteries is performed using an air flow in the top-bottom direction due to the hovering of the air mobility vehicle and an air flow in the front and rear direction due to the cruising of the air mobility vehicle, the efficient cooling performance for the batteries is ensured in a variety of flight modes. Furthermore, the batteries are securely fixed while being cooled by air flows via the heat transfer pads within the battery packs.

Abstract: In an air mobility vehicle, an engine operates as required to provide mechanical driving force or electric energy. A battery is charged with the electric energy from the engine. Main rotors operate using the electric energy of the battery and electric power generated by the engine to perform takeoff, landing, and cruising. Auxiliary rotors are disposed at or adjacent to the center of gravity of a vehicle body and mechanically connected to the engine via a clutch. The auxiliary rotors perform the takeoff, the landing, or the cruising by receiving the mechanical driving force from the engine when the clutch is in an engaged position. A controller monitors the states of the battery and the main rotors and controls the operations of the engine and the clutch.
