Analysis of Thermal Characteristics and Thermal Management Strategy of UAV Power Batteries for Inspection in High-altitude Area
摘要
Abstract
In Qinghai region,drone inspection has emerged as the primary method for regular inspection of photovoltaic power stations.Lithium-ion batteries are one of the commonly utilized battery types in unmanned aerial vehicles.However,in high-altitude areas,due to the influence of temperature and atmospheric pressure,lithium batteries may experience a decrease in capacity and an increased risk of thermal runaway.This study select the corresponding atmospheric pressure and temperature in sunny regions of Qinghai as the research environment,and compare the temperature rise,internal resistance,convective heat transfer coefficient,and entropy heat coefficient data of the battery tested under low-pressure conditions with those obtained under normal pressure.Subsequently,the thermal characteristics of the battery are simulated and a model is built to conduct in-depth research on the characteristics of lithium batteries.According to the simulation and experimental results,a thermal management strategy combining thermal insulation and heating of the battery pack suitable for high-altitude and low-pressure areas is proposed.Finally,6 mm thick aerogel is selected as the thermal insulation material to heat the side of the battery pack,which can effectively ensure the working performance of power batteries in extreme environments in high-altitude areas such as Qinghai,so as to ensure the normal operation of patrol equipment in high-altitude areas.关键词
