Cell Balancing in Lithium-ion Batteries – A Comparative Evaluation
Abstract: Balancing the cells within a battery system is essential for safeguarding against overvoltage, overcharge, and over-discharge, which can lead to system failures and safety hazards. Two commonly employed methods for cell balancing are passive and active balancing. In passive balancing, excess charge is dissipated through resistors, while active balancing involves the controlled flow of charge within the circuit. This paper focuses on the comparison and analysis of passive and two …
