This presentation provides an overview of the self-reported experiences of drivers of electrical vehicles (EV) within the ELectrical Vehicle Intelligent InfraStructure (ELVIIS) project. The goal of the ELVIIS project is to ease the charging process of electrical vehicles by means of intelligent technology. It is a cross industrial collaboration between Viktoria Swedish ICT, Ericsson, Volvo Cars, and Göteborg Energi that started in 2010 and will be finalized by the end of June 2013. Outlined are the research activities that investigate the value of the ELVIIS concept developed within the project. The ELVIIS concept provides a solution in which the user can use and pay for the electricity used in any outlet. Furthermore, the ELVIIS concept allows users to access information related to charging via an in-vehicle system (integrated touch screen), a web application and a smartphone application.
The interviews were qualitatively assessed and analysed from the perspective of the framework of customer-perceived value drivers suggested by Lapierre (2000). The results reveal 326 value drivers,: 114 benefits and 212 sacrifices. The identified benefits and sacrifices are related to the product, service and relationship aspects of the value. The most common benefits are remote access, and alternative information presentation. The most common sacrifices are technical malfunction and unsynchronized subparts of the concept.. In addition, the comparative analysis of the negative and positive words, identified three focus areas:  the suitability of the ELVIIS concept (20 words), i.e., the fitness of the concept to the daily life of the participants, the attractiveness of the service (12 words), i.e., the presentation of the concept to the participants; and the usability of the service (19 words), i.e., the interactivity and ease of use of the concept. A great majority of these words (45 of 51) are positive and highlight the suitability of the ELVIIS concept. It can be concluded that ELVIIS provides convenience to the users and most of the users would recommend it to a friend or use it self in an EV. More specifically, ELVIIS provides a concretisation of the charging experience. The drivers like to set the frames of the charging (how, when, where). However, some functionality was difficult to understand and there was a lack of feedback which made the systems unnecessary difficult to use. Also, the iterative nature of the developments was successful in the sense that the updates of the system were positively perceived; the benefits gradually increased between the different iterations. Interestingly, the attributes of the media used (smart-phone, web, in-vehicle system) for presenting ELVIIS influence the experience of the concept.
