“…The optimal battery SOC range for battery vehicles has been estimated by analyzing the relationship between battery energy efficiency and battery SOC range [17]. There has also been discussion of the energy efficiency of NiMH batteries as they are applied to grid frequency control at various discharge currents [18]. To the best of the author's knowledge, there is still no study yet focusing on what factors will, and how they affect the energy efficiency of lithium-ion batteries in the long run across their entire life cycle.…”

State of Efficiency (SOE) is proposed as a performance indicator of lithium-ion battery in terms of energy efficiency.• The degradation trajectory of SOE for NCA lithium-ion batteries is studied and a linear model is proposed to describe SOE degradation trend.• A number of factors that affect SOE have been identified and studied, including ambient temperature, discharge current, and cutoff voltage.
