摘要：AbstractExisting energy management strategies of HEVs do not consider the inaccuracy of SOC estimation during optimal control formulation. In this paper, the importance and effect of considering this discrepancy in SOC values are analyzed and a mathematical relationship has been established. A sensitivity-based approach is adopted to analyze the problem. Finally, it is demonstrated through theoretical justifications and realistic simulation results that without incorporation of this discrepancy, not only does this lead to exceeding safe boundary conditions for battery but it also substantially affects fuel economy/energy consumption.
