Abstract: How does the reliability of public charging infrastructure affect electric vehicle (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 a 22% purchase price change or 284 miles of EV range, underscoring the importance of reliable public charging.
