A Solar Power System for Electric Vehicles with Maximum Power Point Tracking for Novel Energy Sharing

This paper presents a new system architecture which makes efficient use of the power produced from the photovoltaic (PV) panels used for charging batteries of solar powered electric vehicles. It has power systems for solar powered electric vehicles and solar powered grid which is connected to a charging station or a hub. Several electric vehicles may be charged with its own photovoltaic panel and the hub, which in turn is charged by a large capacity photovoltaic panel or by the electric grid in case the power provided by the panel is not sufficient. Once all the batteries connected to the system reach a certain maximum charge limit, excess energy from the vehicles and the hub is pumped into the grid, thus utilizing the energy that would have otherwise been wasted.
