Transportation electrification is a promising solution to meet the ever-rising energy demand and realize sustainable development. Lithium-ion batteries, being most predominant storage devices, directly affect safety, comfort, driving range, reliability of many electric mobilities. Nevertheless, thermal-related issues batteries such as potential thermal runaway, performance degradation at low temperatures, accelerated aging still hinder wider adoption To ensure safe, efficient, reliable operations lithium-ion monitoring their states critical safety protection, optimization, well prognostics, health management. Given insufficient onboard temperature sensors inability measure battery internal temperature, accurate timely estimation particular importance state monitoring. Toward this end, paper provides comprehensive review techniques in systems regarding mechanism, framework, representative studies. The metrics used characterize are discussed detail first considering spatiotemporal attributes strengths weaknesses applying management also analyzed. Afterward, various methods, including impedance/resistance-based, model-based, data-driven estimations, elucidated, analyzed, compared terms strengths, limitations, improvements. Finally, key challenges real applications identified, future opportunities for removing these barriers presented discussed.
