Title:

Considering Individual Battery Range Needs in Environmental Assessments of Electric Vehicles

Abstract:

Beyond the electricity grid’s carbon intensity, the environmental benefits of electric vehicles (EVs) adoption depend largely on the degree of “travel electrification”, which is the percentage of vehicle- miles-traveled that can be powered by electricity. One key factor that determines travel electrification is the battery range. Previous studies evaluating the environmental impacts of EVs often consider EVs with different battery ranges as parallel scenarios, assuming that all adopters will choose the same EV in each scenario, neglecting the heterogeneity of EV adoption. With the different EV models (with different battery ranges) offered in the market, consumers are likely to make different choices considering their individual travel needs and access to charging infrastructure. In this study, the authors developed an optimization model to identify battery ranges required to satisfy 100% of the driving demands at the individual level. The model is applied to a case study in Beijing using data from both taxis and private vehicles, considering existing charging infrastructure. Their results show that: 1) over half of the taxis have an optimal battery range within 90 to 180 miles while 45% of the private vehicles have an optimal range within 20 to 50 miles, suggesting the feasibility of using existing BEV models to replace conventional vehicles without sacrificing individual mobility demands; 2) a charging station service range of 2 miles or greater is required to reach significant BEV penetration and travel electrification; and 3) the use of fixed battery ranges can underestimate the adoption rate and the overall travel electrification rate.
