6,152 rated or chosen profiles from 769 respondents, in up to 4 tasks of 2 profiles varying on 5 attributes.
One of 2 tables from the same source; this one is the service table. The others are listed under Related tables.
| Description | Second experiment of a sequential design: the same 769 Belgian EV drivers chose between two smart-charging service agreements (minimum battery level, portable power bank, emergency roadside assistance, charging data security, monthly fee) or no agreement. 4 tasks each, choice with an opt-out. |
