中文摘要
本文量化了电动汽车（EV）充电网络的价值，以及网络速度和密度的边际价值。我们估计了一个汽油车驾驶者加油偏好的模型，并模拟这些潜在的未来电动汽车驾驶者在反事实充电网络下如何评价补能时间。驾驶者对补能时间的估值为每小时19.73美元。拥有家庭充电条件的电动汽车采用者因无需前往加油站，每辆车可获得675美元的收益；而使用公共充电的驾驶者，其补能出行与等待时间成本为7,763美元。提高网络充电速度所带来的时间节省，是按比例提高充电站密度的三倍。（JEL D12, H54, Q42, Q58, R41）
Abstract
This paper quantifies the value of electric vehicle (EV) charging networks and the marginal value of network speed and density. We estimate a model of gasoline drivers’ refueling preferences and simulate how these potential future EV drivers value refueling time under counterfactual charging networks. Drivers value refueling time at $19.73/hour. EV adopters with home charging receive $675 per vehicle in benefits from avoiding travel to gas stations, whereas refueling travel and waiting time costs $7,763 for drivers using public charging. Increasing network charging speed yields three times greater time savings than a proportional increase in station density. (JEL D12, H54, Q42, Q58, R41)
