Fig. 1 shows the global sales of EVs, including battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs), as reported by the International Energy Agency (IEA) [9, 10].Sales of BEVs increased to 9.5 million in FY 2023 from 7.3 million in 2002, whereas the number of PHEVs sold in FY 2023 were 4.3 million compared with 2.9 million in 2022.
Therefore, it is crucial to consider the safety and reliability of the “second life” of new batteries during their development and to integrate appropriate management and monitoring systems into the design . The development of new batteries also needs to address future recycling and reuse issues.
To address existing gaps, we introduce the concept of battery engineering safety technologies (BEST). BEST is a systematic technological framework designed to enhance the safety performance and reliability of actual batteries through a comprehensive, hierarchical, systematic approach.
In recent years, a considerable number of mandatory policies and regulations on the safety of new energy vehicles have been introduced, which has resulted in an increase in the technical requirements for the safety of new energy vehicle products and a slight improvement in the safety situation.
This includes advancements in key battery materials and the introduction of safety protection measures. Improvements in battery safety control primarily include the implementation of early warning systems to detect imminent thermal runaway and ensure user safety.
7. Challenges and opportunities The field of battery safety diagnostics is rapidly advancing, spurred by technological innovations and the growing demand for dependable energy storage solutions as part of industry 4.0 .
The power battery, being the core component of an Electric Vehicle (EV), directly impacts both performance and safety. To enhance the safety of power batteries, it is essential to investigate and understand the internal failure mechanisms and behavior characteristics of internal short circuits (ISC) and thermal runaways (TR) in extreme cases.
