Generally, the battery storage unit's initial state of charge (SOC) is inconsistent , . It is easy for some energy storage units to exit operation prematurely due to energy depletion, leading to the reduction of available capacity and the removal of power supply reliability of the power system , , .
Factors affecting the state of a battery. As the number of charge-discharge cycles increases, a chemical reaction occurs in the battery, causing aging, which reduces the SoH of the battery. Aging increases the internal resistance of a battery and decreases its charge-discharge capacity.
During the charging and discharging process, the internal resistance of a battery increase and the constant current (CC) charging time decrease. The SoH can be predicted from the CC charging time of the battery and the battery efficiency, as proposed in this paper.
The efficiency of ESS is caused by the decrease in the difference between the power consumed by charging and the power generated by discharging; therefore, the operating cost for using the battery increases. Efficiency was measured when applying the proposed EMS and BMS algorithms.
The performance of a BMS varies according to the estimation accuracy of the SoC and SoH, indicators of the battery state [ 10, 34, 35 ]. Charge-discharge cycles, temperature, overcharge and overdischarge, and increased internal resistance cause batteries to age, which reduces their capacity.
The optimization process maintains the optimal state of charge of a battery by considering the amount of charge between cells [ 30, 31, 32 ]. As the cycle of a battery increases, the battery ages and its state changes [ 33 ]; therefore, to manage a battery, it is necessary to improve the performance of BMSs.
