A novel Photovoltaic/Battery Structure for Solar Electrical Vehicles [PVBS for SEV]

Abstract

In this paper, we propose a new flexible Photovoltaic/Battery charging Structure for Solar Electrical Vehicles (PVBS), where the interconnection of the system is dynamically changing based on current shading conditions across PV modules to provide intelligent system, as well as to provide flexibility, performance, and efficiency enhancement for the SEV. PVBS is expected to 1) provide a battery charging efficiency improvement over existing employed topologies; 2) provide new means to match the computing load with the PV system performance metrics shading and mismatches; 3) and provide elastic reconfigurable system expected to spur research advancements and innovations to make future SEV design smarter. A MATLAB simulation model and an actual test were conducted to verify the proposed configuration. These results show that the proposed system increases the efficiency of the traditional PV/Battery charging strategies and smoothes the shape of P-V curve to a single peak in the curve.
