Description
Summary:Transportation system around the world is witnessing collusive transition into Electric vehicles (EV) system steeply. This had led to the need of charging stations installation to increase the EV. The main objective of this work is to incorporate solar based charger for EVs. The concept of DC-grid (DC-G) is introduced, which forms a DC-bus with PV and battery system. The Electric vehicles (EVs) are powered through DCG and the power flows from DC-G to vehicle i.e., G2V. The DCG has high rating batteries of the order of 300-400 KW for fast charging. These batteries have the capabilities to reverse the power if required, introducing V2G concept i.e., vehicle to the DC-G. The reverse directional flow of power is facilitated by the Bidirectional Grid-connected DC-Converter (BGDC). Charging station is designed via PV-power whose DC output is controlled via DC-boost converter. The system has been designed in matlab environment at the performance of the Hybrid PV-battery system has been analyzed under the variable solar radiation in order to achieve the constat DC-voltage at the EV terminal. The control of the power has been achieved via PI based controller.
