Optimisation of locally connected renewables for high power EV charging station

Abstract

Constantly increasing uptake of Electric Vehicles (EVs) necessitates a rapidly growing and evolving network of charging stations, including rapid charging systems which attempt to make up for the issue of slow charging. Rapid charging systems, however, can be difficult to implement in larger scale due to the heavy energy supply capacity required and the disruptive nature of the load that they place on the electrical network. This paper examines some of the potential benefits that can be seen by incorporating a Battery Electrical Storage System and directly connected Renewable Energy Systems into EV Rapid charger installations, as well as some of the ways that energy may be managed in such a system.
