Abstract: In order to provide UAVs with effective guidance for its rescue works under extreme environment conditions, flight experiments of it at high temperature of 10 to 60 ℃ and low temperature of 0 to -40 ℃ were conducted in an extreme environment chamber, and effects of extreme temperature on battery performance of UAVs were investigated. The research shows that its performance will be affected when temperature is above 50 ℃ at which battery temperature could not be well managed. When it is below -15 ℃, UAV will consume a lot of power for taking off and will not be able to fly normally when temperature goes below -25 ℃.

Key words: unmanned aerial vehicle (UAV), lithium-ion battery, environmental adaptability, emergency rescue, device security
