A study on thermal management system of lithium-ion batteries for electrical vehicles: A critical review

The current study focuses on Lithium-ion Batteries those have been centre of research attention due to several associated advantages such as long cycle life, low-self discharge, and high energy density, etc. However, the temperature sensitivity is a major issue affecting their cycle life and performance adversely under extreme operational conditions. This fact signifies the need of an effective battery thermal system to be incorporated. This work summarizes recent progress on battery thermal management systems, with special focus on heat pipes-based systems. 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. Further, the hybrid systems are reported to be more effective relative to the individual systems for battery thermal management purposes.
