The thermal management systems covering all temperature conditions were evaluated and summarized. Lithium-ion batteries are extensively utilized in electric vehicles for its high energy density. However, safety problems caused by thermal runaway and performance degradation caused by abnormal temperature must be solved.
The thermal characteristics of lithium-ion battery are determined by the complex electrochemical reaction and electric-thermal conversion. The heat generation consists of four components: reaction heat, ohmic heat, polarization heat and secondary reaction heat.
The maximum temperature and temperature uniformity are considered as the performance parameters to compare the effectiveness of various battery thermal management arrangements. Also, different heat pipe materials, wick structures and working fluids with wide temperature ranges are discussed.
The latest development of cooling system is introduced and evaluated from the perspective of heat transfer medium. The preheating technologies of lithium-ion batteries are analyzed according to different heat sources. The thermal management systems covering all temperature conditions were evaluated and summarized.
Generally, two types of BTMS are used to dissipate the heat from the Lithium-ion battery: (i) Internal BTMS, i.e., inner alteration to minimize heat produced and (ii) External BTMS, i.e., an outside system to improve heat transfer rate within cells. 3.1. Internal BTMS
Thermal stability is the main indicator for improving reliability and safety. Hence, battery thermal management system ( BTMS) is a prime topic of research interest and for electric vehicle makers. The maximum temperature and temperature difference of battery is crucial indicators to calculate the heat transfer rate of BTMS.
