In an effort to anticipate innovative solutions for policies related to the European Green Deal on areas such as smart grids, demand response and renewable electricity integration into the grid, in the last 2.5 years the JRC Living Lab for testing Digital Energy Solutions (hereafter referred to as DES-Lab), operating within the SMARTEN work programme project, has been conducting research by testing and deploying smart charging systems for EVs and on their impact on the use by staff on JRC sites. Using PRISM, a customisable EV-charging wallbox provided by an Italian start-up, the research aimed at studying the impact of smart charging systems on user experience and staff’s use-case specific behaviour; specifically to investigate the behaviour and choices of staff EV owners in response to various incentive schemes for utilising a workplace charging station. The experimentation rounds in 2023 highlighted a number of issues concerning the behaviour of an exemplary client group and their use of the charging stations, particularly the prolonged undue occupancy of the charging points, which is not easy to manage in workplace-charging situations. These findings stressed the need for improved user coordination, better adherence to the rules for fair use of the chargers, and better insight, as well as greater awareness of the optimal charging timing to maximise the use of renewable energy. Whilst the use of targeted communication with users had limited impact on their behaviour, the implementation of authentication and credit-point schemes proved to be more effective in addressing behavioural issues, even though the effects of the more elaborate credit-point scheme appeared to affect mainly those consumers most intensively using the charge field.
