User Survey on Robot-Based Charging for Electric Vehicles

RWTH Publications (RWTH Aachen)

Abstract

Mobile charging robots are autonomous or semi-autonomous systems designed to charge electric vehicles without human interaction. They can navigate to parked vehicles, connect to the charging port, and supply energy from an internal battery. This dataset contains the results of an anonymous online survey conducted between December 2024 and February 2025. The survey aimed to assess user requirements and gain insights into users' perspectives on robot-based charging. It includes information on participants’ attitudes towards electromobility and robotic charging, preferred usage scenarios and interaction concepts, as well as favored pricing models. The provided files include the dataset with an accompanying codebook for data interpretation (UserSurvey_Data_Robot_Based_Charging.xlsx), the full survey questionnaire (UserSurvey_Questionnaire.pdf), and a tree-structured overview of the survey design illustrating the question flow (UserSurvey_Questionnaire_Tree_Structure.pdf). The data were partly collected within the GINI project, funded by the German Federal Ministry for Economic Affairs and Energy (BMWE; formerly the Federal Ministry for Economic Affairs and Climate Action, BMWK) under grant no. 01MV21019A.
