AIRCRAFT BATTERY PACK AND ASSOCIATED COOLING SYSTEM

Last updated:

Abstract:

An electric-powered aircraft battery pack and associated battery pack cooling system. The battery pack comprises a plurality of thermally conductive cooling plates and at least one battery cell coupled with each cooling plate. Heat generated by the battery cells is transferred by conduction to the associated cooling plate. The heat carried by the cooling plates is then transferred by convection to a fluid medium. In some embodiments, heat is transferred from the cooling plate to ambient air or ram air of the aircraft. In some embodiments, heat is transferred from the cooling plate to coolant liquid of a battery pack cooling system.
