Research Progressof Battery Thermal Management Technology for Electric Vehicles
With the rapid development of pure electric vehicles,the use of pure electric vehicles has become more and more common.During the normal operation of a car,lithium batteries generate a lot of heat,but the commonly used air cooling and liquid cooling technologies have poor temperature control effects and are prone to local overheating,which has many limitations.To ensure the safe operation of lithium batteries,thermal management of lithium batteries in electric vehicles is necessary.This article analyzes the main reasons for the generation of heat sources in pure electric vehicle lithium batteries,uses a heat generation model to analyze the heat generation during vehicle operation,summarizes the thermal management methods of lithium batteries using air cooling,liq-uid cooling,heat pipe cooling,composite phase change material cooling,and composite cooling,and also analyzes the advantages and disadvantages of various thermal management methods.By implementing effective thermal management strategies to address the current technological development challenges,and making relevant predictions on the technological development direction of lithium battery thermal management systems for pure electric vehicles,a reference for further research on lithium battery thermal manage-ment systems will be provided.
