Effect analysis on integration efficiency and safety performance of a battery thermal management system based on direct contact liquid cooling

A thermal management system (TMS) is necessary for lithium-ion batteries (LiBs) used in electric vehicles/hybrid electric vehicles (EVs/HEVs), which generate excessive heat during fast discharging and charging. In order to provide low power consumption and efficient heat transfer, finding the most efficient, cheapest, and lightest solution like phase change materials (PCMs) and heat pipes (HPs) is essential. In addition, heat pipe technology is a relatively efficient solution for the TMS for batteries, and it is important to explore the possibility of combining heat pipes with conventional cooling systems. Therefore, this paper focuses on the concept of using heat pipes for TMS in EVs/HEVs and highlights the work done in this field. Additionally, the utilization of TMSs for batteries in EVs/HEVs based on heat pipes combined with nanofluids and phase change materials (PCMs) is also reviewed and discussed. Using of heat pipes for TMS in batteries of EVs/HEVs is proposed to reduce the battery temperature as well as to distribute the temperature uniformly. Further enhancement of temperature distribution can be achieved using integrated HPs with phase change material as well as using nanofluids. Finally, the current study describes the opportunities, challenges, and future prospects for using heat pipes in TMS to enhance the technology and advancements of EVs/HEVs.

Thermal Runaway Induced Casing Rupture: Formation Mechanism and Effect on Propagation in Cylindrical Lithium Ion Battery Module

Funding information National Natural Science Foundation of China, Grant/Award Numbers: 11627803, 11872354, 11872355; Strategic Priority Research Program of the Chinese Academy of Sciences, Grant/Award Number: XDB22040502 Summary Reducing the charging time for electric vehicles (EVs) is considered as a crucial factor to promote consumer interest and improve the competitiveness of EVs in the automotive market. Therefore, the investigation of fast charging protocol becomes increasingly important. In this work, a novel self-adaptive fast charging protocol for cylindrical lithium-ion battery is proposed based on constant incremental capacity (dQ/dV) algorithm, the charging current of which is adaptively adjusted by the intrinsic properties of battery. The cycle test results show that the battery using the new fast charging protocol maintains a capacity of about 90% after 1150 cycles, indicating that the proposed charging protocol can improve the cycle life of the battery, while decreasing the charging time. The fatigue analysis has shown that the capacity fade results predominantly from the loss of active lithium ion and degradation of anode. The anode potential evaluation results show that the anode potential is always greater than zero volt with the proposed fast charging protocol, which avoids lithium deposition. Meanwhile, the post-mortem results of cycled battery indicate that the battery using the proposed charging protocol generate no lithium deposition on anode.
