锂离子电池（LIB）在可再生能源渗透、电气化运输和便携式电子产品等各种领域都有广泛的应用。可靠的电池管理系统（BMS）对于满足LIB系统的可靠性、效率和寿命的期望至关重要。近年来，智能电池及其管理系统的出现，可以有效地克服传统电池管理系统的不足。基于此，本文从系统设计、传感技术、系统集成等方面综述了智能电池和智能电池系统的研究进展。概述了从传统LIB系统向更高智能化的转变以及由此产生的优势/挑战。特别关注的是现有的和新兴的细胞级，多维（机电热）传感技术，可能会发挥关键作用的智能细胞的管理。系统地讨论了从外部到内部嵌入式传感的缓解及其对电池系统性能的潜在好处/影响，以及传感器设计和集成的一般要求。考虑到设计创新和数据传输负担，系统级智能电池集成的潜在变化作为一个开放的前景进行了进一步讨论。
Lithium-ion batteries (LIBs) has seen widespread applications in a variety of fields like the renewable penetration, electrified transportation, and portable electronics. A reliable battery management system (BMS) is critical to fulfill the expectations on the reliability, efficiency and longevity of LIB systems. Recent research progresses have witnessed the emerging technique of smart battery and the associated management system, which can potentially overcome the deficiencies met by traditional BMSs. Motivated by this, this paper reviews the research progresses on the smart cell and smart battery system from multiple aspects, including the system design, sensing techniques, and the potential innovation of system integration. The transition from conventional LIB system towards higher smartness and the incurred advantages/challenges are overviewed. Special focuses are given to the existing and emerging cell-level, multi-dimensional (electro-mechanical-thermal) sensing techniques that may play critical roles in the management of smart cells. The mitigation from external to internal embedded sensing and its potential benefits/impacts to the performance of battery system, as well as the general requirement for sensor design and integration, are discussed systematically. Considering the design innovation and data transmission burden, the potential change of system-level smart battery integration is further discussed as an open outlook.
