title: Data from: Consumer evaluations of charging infrastructure and preferences for fast charging infrastructure

description: We investigate fast-charging behavior during long-distance trips,
 recognizing that the factors influencing charging choices in long-distance
 trips may differ from routine trips, and the trade-off between cost,
 charger availability, detour time, and recharging time can be more
 important. Our analysis is based on data from experiments on fast charging
 choices during long-distance travel by owners of both Plug-in Hybrid
 Electric Vehicles (PHEVs) and Battery Electric Vehicles (BEVs). A total of
 four choice experiments were conducted for each respondent, each featuring
 two unlabeled options with varying charging types, cost per 100 miles,
 charging times per 100 miles, detour time, charger availability, wait
 times, and facility availability. To better understand the exogenous
 factors affecting charging choices, we also examine the interaction
 effects of household income and BEV range.
description: This study conducted a questionnaire survey in February and March
 2024, targeting existing plug-in electric vehicle (PEV) owners. The
 respondents were sampled from the California Department of Motor Vehicles
 (DMV) database, specifically targeting PEVs of model year 2015 and later.
 The survey was distributed to 4,120 PEV owners, of whom 1,265 began the
 survey. A total of 1,102 respondents completed the choice experiment, and
 1,086 completed the entire questionnaire. This survey aims to
 quantitatively evaluate the factors influencing charging preferences for
 long-distance trips using stated preference (SP) data. We designed a
 choice experiment to examine the preferences of BEV owners regarding
 faster charging on long-distance trips. The choice experiment considers
 several factors, including charging type – label (fast: 100kW to 125kW or
 ultrafast: 250kW to 400kW), charging cost, charging time, detour time to
 the charger, whether there is a chance of having to wait at the charger,
 the typical wait time, and whether there were different amenities
 available at each charging location. This design allows us to understand
 preferences for charging speed, time, detour distance waiting time, and
 facilities at charging locations.
description: # Data from: Consumer evaluations of charging infrastructure and
 preferences for fast charging infrastructure We have submitted our raw
 data (**charging_choice_experiment.csv**) ## Descriptions ###
 **charging\_choice\_experiment**\_Data * *id.Response ID*: Each ID
 uniquely represents a respondent. * *income*: the range represents
 respondents' annual household income. some are N/A, meaning the
 respondents did not answer this question. * *gender*: 1 represents male,
 and 0 represents female * *bevUserMake*: This field indicates the brand of
 BEVs, such as Tesla, Kia, Chevrolet, etc. The label "others" is
 used for respondents who are PHEV owners; for these participants, the
 survey randomly assigns a fictional BEV with varying ranges, such as 250
 miles, 275 miles, etc. * *bevFinalRange60PU*: This represents 60% of the
 BEV's range. During the charging choice experiment, respondents were
 presented with a charging scheme that involved recharging their BEVs from
 20% to 80% of the full range, equating to a total recharge of 60% of the
 BEV's range. * *experiment*: totally there are four charging choice
 experiments for each respondent, including choiceExp1, choiceExp2,
 choiceExp3,choiceExp4. * Each choice experiment presents a binary,
 unlabeled choice between 1 and 2. Each option differs in terms of charging
 time, charging cost, detour time, wait time, and available facilities. *
 *Choice (chosen)*: For each binary choice experiment, the option selected
 by the respondents. * *Choice (not chosen)*: For each binary choice
 experiment, the option not selected by the respondents. * *Cost.alt_1*:
 For unlabeled choice 1, the charging cost per 100 miles. 4: $4; 8: $8; 18:
 $18; 25: $25 * *Chargetime.alt_1*: For unlabeled choice 1, the charging
 time per 100 miles. 5: 5 minutes; 10: 10 minutes; 15: 15 minutes; 20: 20

 charging stations. 2: 2 minutes; 5: 5minutes; 10: 10 minutes; 12: 12
 minutes * *Chargewait.alt_1*: For unlabeled choice 1, the chance of wait
 for charging. 0: no chance of waiting; 1: possible chance of waiting; *
 *Waittime.alt_1*: For unlabeled choice 1, the wait time for charging. 0:
