Environmental Implications: Higher energy demands for charging BESS can increase resource usage and potentially lead to higher greenhouse gas emissions if the charging energy comes from fossil fuels. Battery Energy Storage Systems (BESS) experience various losses over time due to several factors, impacting their efficiency and capacity.
Based on the electrochemical-thermal-mechanical coupling battery aging model, the influences of the charge/discharge rate and the cut-off voltage on the battery capacity degradation are studied in this paper, and the optimization of the charge/discharge strategy is carried out.
Self-Discharge: Batteries can lose charge over time when not in use. Coulomb Efficiency (CE): CE measures the efficiency of storing and releasing energy during a cycle. Lower CE indicates more energy lost during each cycle. Operational Factors: Frequent charging and discharging can lead to faster degradation.
Under low temperature and overcharge conditions, the lithium plating occurs on the surface of the negative electrode, resulting in the rapid decay of battery capacity. Meanwhile, the growth of SEI film also increases the internal resistance of the battery and causes the degradation of the battery.
