This paper analyzes the application of a novel Lithium-Sulfur (Li-S) battery with the bilateral solid electrolyte interface to the cruise control of plug-in hybrid electric vehicles (PHEVs). An optimal cruise control strategy based on the dynamic programming algorithm is modified to include battery degradation cost during energy management. The degradation cost of a Lithium-ion Battery is used as a benchmark to analyze the degradation cost of Li-S battery of PHEVs. The comparison results demonstrated that the application of the new Li-S battery significantly reduces the cost of PHEVs.
