Design Analysis of High-Power Level 4 Smart Charging Infrastructure Using Next-Generation Power Devices for EVs and Heavy Duty EVs

Abstract

Trending electric vehicles with different battery technologies need universally compatible and fast chargers. Present semiconductor technology is not suitable for designing high-power-rating converters. The increasing demand for high-capacity electric vehicle chargers requires efficient and optimum advanced material technology. This research presents next-generation material-based smart ultra-fast electric vehicle charging infrastructure for upcoming high-capacity EV batteries. The designed level 4 charger will be helpful for charging future heavy-duty electric vehicles with battery voltages of up to 2000 V. The designed infrastructure will be helpful for charging both EVs and heavy-duty electric trucks with a wide range of power levels. Wireless sensor-based smart systems monitor and control the overall charging infrastructure. The detailed design analysis of the proposed charger using the Simscape physical modeling tool is discussed using mathematical equations.

“…Electric vehicles (EVs) are increasingly becoming popular due to their environmentally advantageous nature, aiming to replace internal combustion engines (ICEs) and reduce carbon dioxide emissions [1][2][3]. By transitioning to electric vehicles, such as battery electric vehicles (BEVs), fuel cell electric vehicles (FCEVs), hybrid electric vehicles (HEVs), ultra-capacitor electric vehicles (UCEVs), solar-charged electric vehicles (SCEVs), and plug-in hybrid electric vehicles (PHEVs), we can significantly reduce pollutants [4,5]. The goal of achieving a carbon-free society by 2030 in Europe and 2050 in India is ambitious but achievable with the swift adoption of EVs and the development of robust charging infrastructure.…”
