This article presents a hierarchical state-of-charge (SOC) balancing control method for a battery energy storage system.
The proposed PCI method can always ensure a maximum power flow of the maximum or minimum SOC storage unit during the SOC balancing process. Moreover, the proposed strategy has been extended to energy storage systems with inconsistent battery cell capacities. 2. SOC balancing control strategies 2.1. Traditional droop SOC balancing control
SOC balancing for capacity inconsistent systems In a system consists of ESUs with inconsistent capacities, the storage units' target energy no longer equals the average value.
At the end of the SOC balancing process, the minimum-SOC unit (i.e., unit 3) keeps a maximum charging power for a short time. This high-power energy interaction among the units further accelerates the SOC balancing speed, leading to the shortest balancing time, Tb = 9.8 s.
