“…Many scholars have studied the energy consumption and environmental characteristics of different types of new energy vehicles, including battery electric vehicles (BEVs) [1,2], hybrid electric vehicles (HEVs) [3,4], plug-in hybrid electric vehicles (PHEVs) [5], fuel cell vehicles (FCVs) [6,7], natural gas vehicles (NGV) [8,9], extended-range electric vehicles (EREVs) [10]. Particularly, Bohnes et al explored relative environmental benefits of EREVs and FCVs over internal combustion engine vehicles (ICEVs) and electric vehicles [11].…”

Many researchers use life cycle assessment methodology to investigate the energy and environmental impacts of energy-saving and new energy vehicles. However, in the context of China, the life cycle energy-saving and emission-reduction effects of extended-range electric vehicles (EREVs), and the optimal applicable vehicle size and driving conditions for EREVs have been rarely studied. In this study, based on the life cycle assessment theory, the resource consumption, energy exhaustion, and environmental impact of EREVs were comprehensively analyzed. In addition, a differential evaluation model of ecological benefits was established for comparing EREVs with other vehicles with different power sources. Finally, scenario analysis was performed in terms of different vehicle sizes and driving conditions. The results have shown that EREV has great advantages in reducing mineral resource consumption and fossil energy consumption. The consumption of mineral resources of EREV is 14.68% lower than that of HEV, and the consumption of fossil energy is 34.72% lower than that of ICEV. In terms of environmental impact, EREV lies in the middle position. The scenario analysis has revealed that, for EREV in China, the optimal vehicle size is the passenger car and the optimal driving condition is the suburban condition. This work helps to understand the environmental performance of EREVs in China and may provide a decision-making reference for the government.
