A Brief Review on Cell Balancing for Li-ion Battery Pack (BMS)

The enormous demand for green energy has forced researchers to think about better battery management for the best utilisation and long-term ageing of the high-power battery bank. The battery management system is yet to reach a mature level in terms of battery protection, balancing, SoC estimation, and ageing factor. This paper extensively reviews battery balancing configurations, their control strategies, security, and applications. It is targeted at providing a comprehensive overview of battery balancing technology to researchers, design engineers, and application engineers working on (BMS). A classified study of more than 50 research papers has been done, and BMS’s state of the art is also given for quick reference.
