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: Aircraft with battery thermal regulation systems, including: an aircraft air inlet and an aircraft air outlet; a battery pack including battery cells; and a battery thermal regulation system including a first air channel, a surface of which is in thermal communication with the battery cells so that air flowing through the first air channel exchanges heat with the cells through the surface; and an airflow device for driving an airflow. The battery thermal regulation system has a first and a second mode operation. In the first mode, the first air channel is fluidly connected with the aircraft air inlet and the aircraft air outlet whereby, during flight of the aircraft, air can enter the aircraft through the air inlet, flow through the first air channel and exit the aircraft through the air outlet. In the second mode, the airflow device drives an airflow through the first air channel.
