摘要: 锂离子电池由于具有优良的电化学特性,在电动汽车及储能等领域得到了广泛的应用,但是其工作性能及安全性受温度的影响较大,因此,需要采用合理有效的热管理系统,以确保电池的温度维持在适宜范围内。本文归纳了常见的热管理系统,总结了风冷、相变材料冷却、热管冷却和液冷的研究现状及优缺点,重点从直接接触液冷和间接接触液冷两方面介绍了当前液冷技术的优化方式。对于单一热管理系统存在的局限性,从耦合热管理系统角度分析了液冷与其他方式相结合的热管理系统的研究现状。提出液冷热管理系统应向综合优化、智能管控的方向发展,特别是与被动散热方式的耦合以及电池管理系统的匹配连接。

Abstract: Lithium-ion battery is widely used in electric vehicles and energy storage because of its excellent electrochemical characteristics, but its performance is greatly affected by working temperature. Therefore, designing the reasonable and effective thermal management system is a key technology to promote the development of lithium-ion battery. This paper summarizes the common thermal management systems, including the research status, advantages and disadvantages of air cooling, phase change material cooling, heat pipe cooling and liquid cooling. Especially it introduces the current optimization methods of liquid cooling technology for the direct contact liquid cooling and indirect contact liquid cooling. For the limitations of a single thermal management system, it also analyzes the thermal management research status of liquid cooling combined with other methods from the perspective of coupled thermal management system. Finally, the direction of comprehensive optimization and intelligent control for liquid cooling management system is proposed, and the liquid cooling combining with the passive heat dissipation and linking of the battery management system has great development potential.
