摘要

Abstract

Firefighting UAVs represent a significant technical apparatus for emergency rescue missions

and as such

they are extensively employed in fire scene reconnaissance and rescue operations due to their high efficiency and flexibility. However

in high-temperature environments

conventional power systems (e.g.

lithium battery packs) can significantly affect the range and safety of UAVs due to insufficient heat dissipation performance or poor heat resistance. This paper proposes methods to enhance the heat resistance of Li-ion battery packs employed in high-temperature environments

with the objective of safeguarding the endurance and operational capability of UAVs in extreme conditions. To this end

simulation is carried out by COMSOL software to analyse the thermal runaway behaviour of lithium batteries. The study reveals that the selection of conductor materials significantly impacts the battery pack's heat resistance.
