Implementation of a Workplace Charging Facilities: Sizing and Preliminary Data Collection

The increasing adoption of electric vehicles is a key element in fighting climate change. Unfortunately, charging operations significantly stress the existing energy infrastructure. For this reason, low-power charging approaches that leverage user working hours to charge the electric vehicles are gaining attention. Realistic usage data are essential for the effective sizing of low-power charging facilities and designing their power flow management algorithms. Unfortunately, available datasets only provide aggregate quantities but do not offer detailed information on the charging facility. This paper aims to fill this research gap by presenting a dataset of real usage data collected in two pilot charging facilities developed at the University of Pisa, Italy. One simple facility consisting of three EV chargers directly connected to the electric grid, while the second one is based on the microgrid concept. The detailed information on charging events, anonymous user data, PV production, and battery usage is collected in the proposed dataset. The database is provided freely to the scientific community as a benchmark for the sizing, development, and validation of workplace charging facilities. It currently contains the data collected during the first 16 months of activity, but it will continue to be updated.
