Efficient thermal management of the large-format pouch lithium-ion cell via the boiling-cooling system operated with intermittent flow

Electric vehicles (EVs) powered by lithium batteries, which are a promising type of green transportation, have attracted much attention in recent years. In this study, a thermoelectric generator (TEG) coupled with forced convection (F-C) was designed as an effective and feasible cooling system for a battery thermal management system. A comparison of natural convection cooling, F-C cooling, and TEG cooling reveals that the TEG is the best cooling system. Specifically, this system can decrease the temperature by 16.44% at the discharge rate of 3C. The coupled TEG and F-C cooling system can significantly control temperature at a relatively high discharge rate. This system not only can decrease the temperature of the battery module promptly but also can reduce the energy consumption compared with the two other TEG-based cooling systems. These results are expected to supply an effective basis of the design and optimization of battery thermal management systems to improve the reliability and safety performance of EVs.

Lifetime Extension

A lithium-ion capacitor (LiC) is one of the most promising technologies for grid applications, which combines the energy storage mechanism of an electric double-layer capacitor (EDLC) and a lithium-ion battery (LiB). This article presents an optimal thermal management system (TMS) to extend the end of life (EoL) of LiC technology considering different active and passive cooling methods. The impact of different operating conditions and stress factors such as high temperature on the LiC capacity degradation is investigated. Later, optimal passive TMS employing a heat pipe cooling system (HPCS) is developed to control the LiC cell temperature. Finally, the effect of the proposed TMS on the lifetime extension of the LiC is explained. Moreover, this trend is compared to the active cooling system using liquid-cooled TMS (LCTMS). The results demonstrate that the LiC cell temperature can be controlled by employing a proper TMS during the cycle aging test under 150 A current rate. The cell’s top surface temperature is reduced by 11.7% using the HPCS. Moreover, by controlling the temperature of the cell at around 32.5 and 48.8 °C, the lifetime of the LiC would be extended by 51.7% and 16.5%, respectively, compared to the cycling of the LiC under natural convection (NC). In addition, the capacity degradation for the NC, HPCS, and LCTMS case studies are 90.4%, 92.5%, and 94.2%, respectively.

Abstract The lithium-ion battery is promising energy storage that provides proper stability, no memory effect, low self-discharge rate, and high energy density. During its usage, batteries generate heat caused by energy loss due to the transition of chemical energy to electricity and the electron transfer cycle. Consequently, a thermal management system by cooling methods in the battery is needed to control heat. One of the cooling methods is a passive cooling system using a phase change material (PCM). PCM can accommodate a large amount of heat through small dimensions. It is easy to apply and requires no power in the cooling system. This study aims to find the best type of PCM criteria for a Lithium-ion battery cooling system. The research was conducted by simulations using computational fluid dynamics. The variations were using PCM Capric Acid and PCM Hexacosane, with thickness variations of 3 mm, 6 mm, and 9 mm. Hexacosane PCM with 9 mm thickness indicates the best result to reduce heat up to 6.54°K, demonstrating a suitable passive cooling system for Li-ion batteries.

Thermal Management System

Abstract With the development of modern technology and the economy, environmental protection and sustainable development have become the focus of global attention. In this paper, the promotion and development of electric vehicles have bright prospects, and they are also facing many challenges. Under different operating conditions, various safety problems of electric vehicles emerge one after another, especially the potential safety hazards caused by battery overheating that threaten electric vehicles' development process. In this paper, a new indirect liquid cooling system is designed and optimized for cylindrical lithium-ion batteries. A variety of design schemes for different cooling channel structures and cooling liquid inlet direction are proposed, and the corresponding solid-fluid coupling model is established. COMSOL Multiphysics simulation software models, simulates and analyses cooling systems. An approximate model is constructed using the Kriging method，and it is considered to optimize the battery cooling system and improve the optimization results. Sensitivity parameter analysis and system structure optimization design are also carried out on the influencing factors of the battery thermal management. The results indicate it effectively balances and reduces the maximum core temperature and temperature difference of the battery pack. Compared with the original design, from the optimized design of these factors, which based on method of the non-dominated sorting genetic algorithm (NSGA-II), there is an excellent ability on the optimized thermal management system to dissipate thermal energy and keep the overall cooling uniformity of the battery and thermal management system. Furthermore, under thermal abuse conditions, the optimized system can also prevent thermal runaway propagation. In summary, this research is expected to provide some practical suggestions and ideas for the engineering and production applications and structural optimization design carried by electric vehicles.
