Design of solar parking lot for 20 electric vehicles in St.John’s NL

Abstract

This paper discusses the design of a solar parking lot in the off-grid mode for charging 20 Electric vehicles for Newfoundland condition. The selected site is near the Canada National Research Council (NRC) building located in the Memorial University of Newfoundland St. John’s, Newfoundland, Canada. Smart EQ ForTwo was considered as the electric vehicle (loads) for the design. For the selected site, a system is optimized using homer software. The proposed charging infrastructure is equipped with current sensors that communicate the power generation data and power consumption data in real-time to the cloud for direct PV run or utilize the excess power stored in the battery bank. The decision is made to charge the connected EV using an algorithm that makes use of the data, sent by the sensors with the help of IoT. Complete system design and simulation results are presented in the paper.
