Claims6
A method for electric aircraft operation, comprising:
- receiving a flight plan from a user, the flight plan comprising a flight distance;
- based on the flight distance and a thermal mass of a battery pack, determining a takeoff temperature threshold for the battery pack;
- cooling the battery pack to or below the takeoff temperature threshold by circulating a working fluid through the battery pack;
- and
- after cooling the battery pack to or below the takeoff temperature threshold, controlling the aircraft according to the flight plan.
