Are battery energy storage systems inconsistency optimized under fixed topology?

Consistency optimization scheme under fixed topology is validated. Future research challenges and outlooks are prospected. With the rapid development of electric vehicles and smart grids, the demand for battery energy storage systems is growing rapidly. The large-scale battery system leads to prominent inconsistency issues.

What does SoC mean in a battery?

In a battery, SoC (State of Charge) represents the current charge level. When (SOC=0), the battery is fully discharged, and when (SOC=1), the battery is fully charged.

What is the SOC of a battery pack before optimization?

Specifically, the SOC of the battery pack before optimization began to deviate at about 2000s. With the increase of discharge depth, the inconsistency of SOC increases gradually. At the discharge end, the maximum SOC deviation is about 10.8 %. However, the SOC of the comparison experiment has a high degree of consistency in the whole process.

What is the difference between SOC and voltage of battery pack?

The SOC and voltage of the battery pack before and after optimization are obviously different. Specifically, the SOC of the battery pack before optimization began to deviate at about 2000s. With the increase of discharge depth, the inconsistency of SOC increases gradually. At the discharge end, the maximum SOC deviation is about 10.8 %.

What does SoC mean in energy management?

SOC is monitored and managed by the Energy Management System. For example, if a battery has an SOC of 80%, it means that 80% of its total energy capacity remains available for use. Conversely, an SOC of 20% implies that 80% of the energy has already been consumed, leaving only 20% of the capacity remaining.

How does SoC error estimation work in a battery management system?

Although the battery is aging, the SOC error estimation system maintains the setting range using a low-cost 8 bit micro-controller. The proposed method can track and correct the open-circuit voltage against capacity in the battery management system by comparing the capacity error with the coulomb counting and look-up table methods.
