摘　　要：发展集成多元传感器件的智能电池技术有望解决传统电池系统由于传感信号匮乏导致的电池状态估计精度低、运维管控难度大的痛点,是近年的研究热点。从电、热、气、力、声等传感信号出发,介绍了电池智能传感技术的最新进展及典型工作,阐述了不同传感信号对于理解电池老化、失效、失控等过程的机理以及开发高可靠高安全运维技术的意义,并分析了不同传感技术所面临的问题和挑战。从传感器、电芯设计制造、信号采集与传输、智能运维系统等方面展望了智能电池技术发展所亟需解决的关键技术挑战。Conventional battery systems face the challenges of low accuracy in battery state prediction and high difficulty in battery management due to limited signals collected.Developing the so-called smart battery that has multiple types of sensors can potentially resolve the above issues.Here,the recent progress of battery smart sensing in terms of electrical,thermal,gas,mechanical,and acoustic sensing was reviewed.Specifically,how acquiring these signals can contribute to the understanding of battery aging,failure,and thermal runaway processes and to the development of high-safety and high-reliability battery management systems was discussed.The challenges faced by each type of sensing were further discussed.Finally,an outlook for the barriers to be conquered for the development of a smart battery from the aspects of sensors,battery design and manufacturing,signal acquisition and transmission,and intelligent battery control strategies was provide.
