摘要： 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.

摘要： A battery module includes first and second neighboring battery cells. The battery module also includes a cold-plate configured to remove thermal energy from the first and second battery cells. The cold-plate includes first and second sections configured to seat respective first and second cells. The first section defines a first vent arranged directly adjacent the first cell and configured to exhaust gases therefrom. The cold-plate additionally includes a first closure element arranged within and configured to block the first vent in a first mode to transfer thermal energy from the first cell to the cold-plate. The first closure element is additionally configured to open the first vent in a second mode when the first cell undergoes a thermal event to exhaust gases and transfer thermal energy from the first cell through the first vent and thereby control propagation of a thermal runaway in the battery module.
