1. A system for battery temperature management in an electric aircraft, wherein the system comprises:
a plurality of battery cells, wherein the battery cells are comprised of pouch cells;
at least a sensor communicatively connected to a computing device, wherein the at least a sensor is configured to collect a temperature datum of the plurality of battery cells;
a plurality of temperature regulating elements disposed between the plurality of pouch cells, wherein the plurality of temperature regulating elements are configured to regulate a temperature of the plurality of battery cells, wherein at least one temperature regulating element comprises a heating element including a sheet heater, wherein the sheet heater comprises a resistive film wrapped around a pouch cell of the plurality of pouch cells; and
a computing device communicatively connected to the plurality of temperature regulating elements, wherein the computing device is configured to:
determine a target temperature of the plurality of battery cells as a function of a flight plan and battery considerations, wherein the target temperature is further determined as a function of wind speed;
determine the temperature of the plurality of battery cells by comparing the temperature datum to the target temperature;
send a notification of the temperature of the plurality of battery cells to a user interface; and
direct the plurality of temperature regulating elements to modify the temperature of the plurality of battery cells as a function of the target temperature.
