Performance Analysis Based on Desert Rescue UAV Power Battery in High Temperature Environment

Abstract

The main purpose of this paper is to analyze and discuss the performance of the lithium iron phosphate battery and the new lithium titanate battery commonly used in UAV that affect the endurance in high temperature environment. This paper first introduces the functions of desert rescue UAV and the development status of UAV power battery technology. This paper first points out the main factors that affect their endurance at high temperature, expounds the reasons for the failure of lithium-ion batteries and high-temperature polymer batteries at high temperature, and introduces the materials and general performance characteristics of the two types of batteries, and then reviews the methods and results of various studies on the performance of lithium-ion batteries and lithium polymer batteries at high temperature. Finally, this paper points out the shortcomings of the existing research and points out the direction for the future development. By comparing the working performance of the two batteries at high temperature and combining with the practical problems that need to be considered in production and use, this paper puts forward selection suggestions according to the existing conditions, so that later workers can choose the type of UAV power battery according to different working environments.
