锂离子电池故障预测及健康管理技术进展

The prognosis and health management (PHM) technology of lithium-ion batteries helps reduce the probability of failure and improve the service time by analyzing current reliability and formulating a comprehensive control strategy. Analysis and forecasting of battery failure are key components of battery PHM technology. This article examines the state of research on the main PHM technologies, such as reliability analysis, testing, and growth technology, failure diagnosis and early warning algorithms, failure model based on digital twin technology, and fault analysis and probability prediction. And the article introduced the general architecture for PHM technology on cloud battery management systems for electric vehicles. The advantages and disadvantages of existing technologies are summarized, and the challenges and future perspectives of PHM technology are prospected.
