12,304 rated or chosen profiles from 769 respondents, in up to 8 tasks of 2 profiles varying on 6 attributes.

One of 2 tables from the same source; this one is the purchase table. The others are listed under Related tables.

About this table

Description	Discrete choice experiment with 769 Belgian drivers choosing between two hypothetical home electric-vehicle chargers that differ in smart-charging control, solar charging, two-way charging, peak-use management, annual bill reward and price, or keeping their current charger. 8 tasks each, choice with an opt-out.

Notes

Conjoint table (irw_conjoint_2). Choice among Charger 1, Charger 2 or keeping the current charger (no advanced features, no reward), described by smart-charging control, solar charging, two-way charging, peak-use management, annual reward and price; the current-charger option has no levels, so it is the opt-out (choice = 0 on both profiles when picked). 8 tasks of a fixed blocked design (5 versions); level text from the questionnaire's example cards; 769 respondents after the authors' validity filter (905 in the raw file).

These notes describe the source data, which the IRW reproduces as released. All notes are listed on the Data Notes page.
