Bidirectional Electric Vehicle Based on off-board Charger Design

Abstract

The continuity of the energy grid is the result of building a breed of ever-increasing demand for innovative electrocatalysis and the most effective solutions that qualifies the active sharing by end users in the balanced and trustworthy management of energy systems. One emerging prospect for such bidirectional exchange of electrical energy through the network and consumers is scope for the development of bidirectional energy trading among energy suppliers and owners of electric vehicle. It is proposed in this article to design a bidirectional, 3-phase, 2-stage off-board EV charger. The first step works as an AC/DC converter through the charging process, runs as 3-phase inverter and improves power factor while power is exchanged from the V2G. The next step is a DC/DC converter connected to first step via a DC-bus. A grid bypass filter is prepared to activate grid interconnection without noticeable problems in power quality. Suggested design and innovative infrastructure were examined during a simulation-based MATLAB software environment by connecting charger to a 3-phase micro-network and the results are consistent with the performance of suggested charging topology.
