In this study the performance indicators have been monitored, as well as the response time of the station, and its charge rate over the day. This analysis has taken into account the frequency of the requests, as well as the capacity of battery used by the mobile station. Keywords: charging station, mobile charging station, battery, queuing processes, electric vehicle. 1. INTRODUCTION The adopting, at the beginning of the previous century, of fossil fuels as an energy source for internal combustion engines used in transport, has caused a series of negative effects on the environment and global security. As a means to counteract these effects, on one side, fossil fuels are being replaced by ecological fuels, while on the other side the means of propulsion are being changed from internal combustion engines to electric, or a combination of the two (Felseghi and Papp, 2014). In this context, the new „Romania's Energy Strategy for 2014-2030 with an outlook for 2050” has Clean Energy as a strategically objective in compliance with the directive CE 2016/30.11.2016 (European Commission. Clean Energy for All, 2016), and Electromotive as a priority direction. Functional performances, still unsatisfactory in terms of range, and recharging time makes it necessary to increase interest and public acceptance of electric vehicles. This can be done in two ways; one targeting direct and indirect financial incentives, and another improvement of the recharging * Corresponding authors: Simona Raboaca, E-mail: simona.raboaca@icsi.ro, Phone: 0250 732 744, Fax: 0250 732 746
