Abstract: Methods for thermally regulating batteries of aircraft are provided. The aircraft comprises: an air inlet; an air outlet; a battery pack comprising battery cells; and an air channel in fluid communication with the air inlet and the air outlet, a surface of the air channel being in thermal communication with the battery cells whereby air flowing through the air channel exchanges heat with the battery cells through the surface of the air channel. The methods comprise: connecting an external supply of air to the air inlet of the aircraft; and delivering a flow of air through the air channel using the external supply of air. A kit comprising the aircraft and the external supply of air is also provided.

Abstract: An aircraft including a battery pack having a plurality of battery cells arranged to vent into a venting region of the battery pack. A path is defined between the venting region and an exterior of the aircraft, whereby thermal products vented by the cells can exit the aircraft via the path. In some embodiments, the venting region is or is in fluid communication with an air channel through which air flows from an aircraft air inlet to an aircraft air outlet. In other embodiments, the path joins the venting region and an opening in an external surface of the aircraft.
