插电式混合动力电动汽车（PHEV）被认为是实现能源和环境目标的短期技术，也是向可行的全电动汽车过渡的一步。为了在市场和影响分析中用对潜在插电式混合动力汽车驾驶员行为的观察来取代假设，对美国2,373个新车购买家庭进行了基于互联网的调查。该仪器要求家庭回答问题，完成驾驶和停车日记，然后完成几个PHEV设计练习。从所得数据中可以得出三个结论。首先，至少有一半的目标人群已经配备了在家充电的设备，但很少有机会在工作场所或其他地点充电。其次，该研究发现，受访者对四种可能的PHEV属性有着广泛的兴趣：燃油经济性（在电量消耗和电量维持操作中），混合动力与全电动操作，车辆处于电量消耗模式的距离以及充电速度。然而，增加燃油经济性的吸引力似乎是最高的，而更快的充电似乎是最低的。此外，对全电动操作的兴趣不大。第三，考虑到前两点，据估计，大约三分之一的目标人群既有为插电式混合动力汽车充电的基础设施，又对具有插电式功能的车辆感兴趣。政策、技术和能源供应商可以利用这些信息来了解他们的计划、设计和目标是否与目前的理解一致，或者是否有利于促进美国汽车买家对插电式混合动力汽车的新理解。
Plug-in hybrid electric vehicles (PHEVs) are proposed as both a near-term technology to achieve energy and environmental goals and as a transitional step toward viable all-electric vehicles. To replace assumptions with observations of potential PHEV drivers’ behavior in market and impact analyses, an Internet-based survey of 2,373 new-car–buying households in the United States was conducted. The instrument required households to answer questions, complete a driving and parking diary, and then complete several PHEV design exercises. Three conclusions could be drawn from the resulting data. First, at least half of the target population is already equipped for at-home vehicle recharging but has little opportunity for recharging at the workplace or other locations. Second, the study found that the respondents had widely varied interests in four possible PHEV attributes: fuel economy (in both charge-depleting and charge-sustaining operations), blended versus all-electric operation, the distance over which the vehicle is in the charge-depleting mode, and the recharging speed. Nevertheless, the appeal of increased fuel economy appears to be the highest and that of faster recharging appears to be the lowest. Furthermore, there is little interest in all-electric operation. Third, given the previous two points, it was estimated that about a third of the target population has both the infrastructure to recharge a PHEV and interest in a vehicle with plug-in capabilities. Policy, technology, and energy providers may use this information to understand whether their plans, designs, and goals align with these present understandings or whether it would be collectively beneficial to foster new understandings of PHEVs among U.S. car buyers.
