Performance of Various Integrated Converters at Charging Station of EV's

Industries are increasingly compelled to reduce carbon dioxide (CO2) emissions due to environmental concerns and stringent regulations. The automotive sector is tackling this challenge by focusing on vehicle electrification, which includes plug-in hybrid electric vehicles (PHEVs), hybrid electric vehicles (HEVs) and battery electric vehicles (BEVs). BEVs, in particular, offer the promise of zero tailpipe emissions and substantial long-term CO2 reduction. However, the broad embrace of electric vehicles (EVs) introduces significant challenges to power grids, primarily due to new loads and peak demand fluctuations. To mitigate these issues, Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) technologies have been proposed, allowing for bidirectional energy flow and adaptive charging rates. Fast DC chargers, essential for quick EV charging, present additional concerns such as harmonics and peak demand, especially in weaker power systems. Addressing these concerns involves strategies like using low voltage DC-Buses, local battery storage, and integrating renewable energy sources. This work focuses on integrating various converters to optimize the charging of energy storage systems (ESS) and further charging of EVs. The system's common bus voltage is set at 1000 V, utilizing an AC to DC converter and single-inductor-energy-storage cell-based switched capacitor (SIESC-SCs) converters to achieve this output. A bidirectional converter and a buck converter connected to the common DC bus provide 800 V for charging both EVs and ESS. This configuration is implemented in MATLAB/SIMULINK, demonstrating advancements in EV charging infrastructure and potential innovations in electric vehicle technology.
