摘要:

锂离子电池的性能直接影响电动汽车的续航、安全性和可靠性。低温环境下,锂离子电池功率特性变差、循环寿命衰减、可用容量降低,同时面临低温充电难、充电易析锂等问题,这些因素阻碍了电动汽车的发展。低温加热技术是电池热管理系统的核心技术之一,是缓解动力电池在低温环境下性能衰减的关键。本文综述了包括内部自加热法、MPH加热法、自加热锂离子电池、交流加热法等低温快速加热方法的最新研究进展,并总结了不同加热方法的加速速度、能量消耗、循环容量损失等关键性能参数。另外归纳了动力电池低温热管理系统的设计目标,并对不同加热方法性能进行比较分析。分析结果表明,交流加热法相比于其他方法更具优势,尤其在能量消耗、电池老化方面。最后,指出现有研究在电池老化机理、电池组/包层面加热策略方面的不足,并展望了未来的研究方向。本文内容有利于低温加热方法的发展和实际工程问题的解决,可为后续电动汽车动力电池的低温快速加热技术研究、低温热管理系统设计提供参考。

Abstract:

The performance of a lithium-ion battery affects the driving range, safety, and reliability directly. Furthermore, as the power characteristics of the lithium-ion battery degrade, the cycle life attenuates, and the available capacity is reduced in low-temperature. Furthermore, there is a high risk of lithium plating at the surface of the anode when the battery is charged at extremely low temperatures. These factors hamper the development of electric vehicles. Battery warm-up is one of the core technologies of the battery thermal management system to alleviate the deterioration of batteries in cold weather. To this end, this paper reviewed the recent research progress of rapid heating methods, including internal self-heating, mutual pulse heating (MPH), self-heating lithium-ion battery, alternating current heating. Key performance parameters such as heating time, energy consumption, and degradation of various heating methods were also summarized. The design considerations of battery management systems in low-temperature conditions were provided, and the performance of different heating methods was compared. The results demonstrated that alternating current heating had advantages over the other methods, especially in energy consumption and degradation. Finally, future trends of battery heating methods were discussed, and more breakthroughs should be made in battery aging mechanisms and preheating strategies in a battery module/pack level. The research was helpful to promote the development of heating methods and solve engineering problems. It also provided plenty of references for the research of rapid heating methods and designing a battery thermal management system at low temperatures.
