本文旨在研究电动汽车用户在充电时间方面的选择行为。重点是一天中最后一次出行后的正常充电，而呈现的替代方案是不充电、到达后立即充电、夜间充电以及其他时间充电。一个混合logit模型与未观察到的异质性的面板数据提取的电池电动汽车的使用在日本为期两年的现场试验。使用商用和私人车辆的单独模型获得的估计结果表明，充电状态、下一个旅行日之前的天数间隔以及下一个旅行日行驶的车辆公里数是用户是否对车辆充电的主要预测因素，快速充电的体验对正常充电产生负面影响，并且用户倾向于在试验的后半段在夜间充电。另一方面，对于商用车辆，在工作日的最后一次行程之后正常充电的概率增加，而对于私人车辆，正常充电的概率降低。商业车辆在夜间到达时往往不收费，而私人车辆往往立即收费。此外，夜间充电与立即充电和在其他时间充电的相关性表明，可以鼓励在非高峰时段充电以减轻电网上的负载。这一发现得到了夜间充电替代方案的高方差的支持。(C)2015爱思唯尔有限公司版权所有。
This paper aims to examine choice behavior in respect of the time at which battery electric vehicle users charge their vehicles. The focus is on normal charging after the last trip of the day, and the alternatives presented are no charging, charging immediately after arrival, nighttime charging, and charging at other times. A mixed logit model with unobserved heterogeneity is applied to panel data extracted from a two-year field trial on battery electric vehicle usage in Japan. Estimation results, obtained using separate models for commercial and private vehicles, suggest that state of charge, interval in days before the next travel day, and vehicle-kilometers to be traveled on the next travel day are the main predictors for whether a user charges the vehicle or not, that the experience of fast charging negatively affects normal charging, and that users tend to charge during the nighttime in the latter half of the trial. On the other hand, the probability of normal charging after the last trip of a working day is increased for commercial vehicles, while is decreased for private vehicles. Commercial vehicles tend not to be charged when they arrival during the nighttime, while private vehicles tend to be charged immediately. Further, the correlations of nighttime charging with charging immediately and charging at other times reveal that it may be possible to encourage charging during off-peak hours to lessen the load on the electricity grid. This finding is supported by the high variance for the alternative of nighttime charging. (C) 2015 Elsevier Ltd. All rights reserved.
