Hierarchical SOC Balancing Controller for Battery Energy Storage System

This article presents a hierarchical state-of-charge (SOC) balancing control method for a battery energy storage system. In the presented system, multiple battery cells are connected in-parallel at the inputs of a single-inductor multiinput single output (SI-MISO) power converter to form a battery module and multiple battery modules are connected in series at the output to form the complete batter...
