ABSTRACT
Electric Vehicles (EVs) play a vital role all over the world in declining carbon emissions in the automotive industry. The charging infrastructure of EVs highly challenging phenomenon particularly the DC fast electric vehicle charging station provided the main issues in terms of quick charging time which impacts the overloading and forecasting of the main grid. Hence, the bidirectional power flow charger is to be used between EV and grid (V2G and G2V) to enhance grid stability in terms of load leveling and load shaving. In this chapter, there is a detailed review of the promising DC–DC converter topologies for V2G/G2V technology are presented, such as snubber assist zero-voltage zero-current (SAZZ) converter and re-lift converter, and discussion on modeling and modes of operation. These proposed converters are to be utilized as bidirectional DC–DC converters in EV fast charging, and its architecture is discussed, and how it reduces impacts on power grid stations.
