摘要

公共充电基础设施的可靠性如何影响电动汽车的采用？大量的公共和私人投资正在扩大电动汽车充电网络，但人们越来越担心现有充电器的可靠性差及其对电动汽车采用的潜在影响。利用一项全国性调查的数据，我们采用了一个选择模型来量化感知充电可靠性对美国人购买新车或二手电动汽车意愿的影响。通过随机分配参与者接收将公共充电描述为非常可靠或非常不可靠的信息，我们展示了可靠性感知对电动汽车购买意愿的因果影响。我们发现，感知可靠性的差异相当于将价格改变32%的购买预算或将里程改变366英里，这强调了可靠的公共充电的重要性。

Poor reliability of public charging stations can impede the growth of the electric vehicle market

How does the reliability of public charging infrastructure affect electric vehicle (EV) adoption? Substantial public and private investments are expanding EV charging networks, but concerns are growing about the poor reliability of existing chargers and its potential impacts on EV adoption. Using data from a nationwide survey, we employ a choice model to quantify the effects of perceived charging reliability on Americans’ intentions to purchase new or used EVs. By randomly assigning participants to receive information characterizing public charging as either very reliable or very unreliable, we show a causal effect of reliability perceptions on EV purchase intentions. We find that differences in perceived reliability are equivalent to changing price by 32 % of purchasing budget or changing range by 366 miles, underscoring the importance of reliable public charging.

期刊介绍： Transport Policy is an international journal aimed at bridging the gap between theory and practice in transport. Its subject areas reflect the concerns of policymakers in government, industry, voluntary organisations and the public at large, providing independent, original and rigorous analysis to understand how policy decisions have been taken, monitor their effects, and suggest how they may be improved. The journal treats the transport sector comprehensively, and in the context of other sectors including energy, housing, industry and planning. All modes are covered: land, sea and air; road and rail; public and private; motorised and non-motorised; passenger and freight.
