插电式混合动力汽车（phev）提供了减少石油进口、温室气体排放和燃料成本的潜力，但高昂的前期成本使许多潜在买家望而却步。由于驾驶模式、车辆续航里程、可用能源管理以及影响电池磨损和汽油消耗的充电策略等因素的敏感性，将自动驾驶汽车与传统替代方案进行经济比较变得非常复杂。确定合理的电池更换时间表使问题更加复杂。国家可再生能源实验室开发了电池所有权模型来解决这些问题和相关问题。当采用高保真电池退化模型和经济合理的电池更换计划时，本文将使用电池所有权模型来检验PHEV经济性对驾驶模式、车辆续航里程、可用能量管理和充电策略的敏感性。我们发现，能量管理方法、全电续航里程、最大寿命开始充电状态和基本充电时间对插电式混合动力汽车的总拥有成本影响较小；然而，插电式混合动力车的经济性确实对驾驶模式和工作充电器的可用性很敏感。
Plug-in hybrid electric vehicles (PHEVs) offer the potential to reduce oil imports, greenhouse gases, and fuel costs, but high upfront costs discourage many potential purchasers. Making an economic comparison with conventional alternatives is complicated in part by sensitivity to drive patterns, vehicle range, available energy management, and charge strategies that affect battery wear and gasoline consumption. Identifying justifiable battery replacement schedules adds further complexity to the issue. The National Renewable Energy Laboratory developed the Battery Ownership Model to address these and related questions. The Battery Ownership Model is applied here to examine the sensitivity of PHEV economics to drive patterns, vehicle range, available energy management, and charge strategies when a high-fidelity battery degradation model and financially justified battery replacement schedules are employed. We find that energy management methodology, all-electric range, maximum beginning-of-life state of charge, and basic charge timing generally have a small impact on the total cost of ownership of PHEVs; however, PHEV economics do prove sensitive to drive patterns and the availability of an at-work charger.
