Analysis of the discrete choice model representing the electric vehicle owners’ behavior in Slovakia

Abstract

The paper deals with the decision-making process of the electric vehicle (EV) owners at the charging station. Firstly, the paper presents a theoretical basis for the definition of discrete choice systems. Consequently, the process of the stated preference survey design, used to obtain data about the EV owners’ decisions at the charging station, is presented. The SP survey consisted of 18 hypothetical scenarios and socio-demographic questions. The SP survey was carried out from July 2020 to October 2020, and 289 residents of Slovakia with an age higher than 18 (the threshold necessary for a driving license) have taken part. This results in a sample of 5192 different responses. Based on the obtained data, the EV owners’ behavior prediction model is defined and its parameters are estimated using the maximum likelihood estimation method and 90% of the sample data. Furthermore, the presented model is validated with the rest of the sample data and recommendations for future work are defined.
