I. Introduction
Admittedly, the increasing human needs for mobility combined with the use of private vehicles are primary causes of serious environmental and social problems worldwide, having a negative impact on the quality of life [1], [2]. The high use of private cars is known to be a source of high levels of air and noise pollution, as well as parking and traffic congestion problems, mainly in urban areas [2], [3]. Relevant studies indicate that conditions of traffic congestion are typically observed at peak hours when people commute to work [4], [5]. In this context, carsharing serves as a substitute for private car ownership that has also positive contribution to urban mobility, mainly because the shared cars are used more efficiently

More specifically, the input stage of the proposed charger topology combines a three-phase full-bridge diode rectifier with three single-stage active power filters, while the output stage consists of six interleaved groups of two parallel DC–DC converters. The authors in [28] employ an adaptive hybrid duty cycle control mechanism for a fast charging switching-based charger in order to reduce the circuit complexity and better control the charging process of multiple batteries using a single power converter. The work in [29] follows a different topology, which combines a multiport converter with a stationary storage port, aiming at the reduction of the current required from the grid in the frame of the fast charging process of EV batteries. Last, the authors in [30] discuss a fast charger based on a neural-fuzzy approach (the so-called NeuFuz technology), using a NiCd battery pack as a test case application.
The aim of the present paper is to introduce a fast charging solution to cover the demand of a fleet of EVs organized in an e-carsharing system, assuming its base at a university campus and taking into account field measurements from the university parking lot for the potential utilization of the EVs. In contrast to the existing literature, the proposed fast charging infrastructure considers a battery-to-battery (B2B) circuit design implementing dedicated charging posts to the charging
