Safety enhancement for lithium-ion batteries (LIBs) has received a lot of attention from academic and industrial fields. However, there is a lack of attention from the perspective of the application power electronics (PEs) in the systems. This tutorial gives a presentation about PE-based safety enhancement technologies for LIBs, mainly focusing on battery management. It introduces the latest advances in battery protection, balancing, monitoring, and lifetime improvement, all based on PE technologies. Detailed discussion and future research opportunities are given. This tutorial aims to provide a reference for PE researchers who want to make some efforts in LIB safety.
