Thermal Performance Analysis of Novel All-Climate Lithium-Ion Battery Thermal Management System Coupled with Heat Pipes and Phase Change Materials
摘要
Abstract
The battery thermal management system is an essential approach to ensuring the safe and efficient operation of energy storage batteries under different operating conditions.Considering the high latent heat of phase change materials and the superior thermal conductivity of heat pipes,this paper designs a novel lithium-ion battery thermal management system for lithium-ion batteries coupled with heat pipes and phase change materials coupling that can realize the requirements of heat removal and heat preservation under all-climate conditions.The thermal performance of such a battery thermal management system is numerically investigated.Under low-temperature environments,the paper analyzes the influences of insulation material thickness and initial battery temperature on the duration of heat preservation by simulating the battery discharge process and the temperature drop after discharge.In contrast,at normal and high ambient temperatures,it proposes heat removal strategies based on single or coupled measures of phase change materials,heat pipes,and gas/liquid cooling channels for the safe operation of lithium-ion batteries,especially at 0.5C to 2.0C discharge rates.The current work could provide theoretical guidance for the efficient design of a lithium-ion battery thermal management system covering the whole climatic range.关键词
