Multiple Sources Off-Board Electric Vehicles Charging Station, Different Techniques, Standards and Challenges

In recent years, Electric vehicle (EV) hybrid (has grid-connected modes as well as development kit potential) and off-grid (standalone mode) charging systems have seen a rise in research attention. To expand EV adoption globally, the key motivations to offer a smooth infrastructure of charging in rural as well as urban locations where the utility circuit is non-dependable or absent. In this regard, this article examines the off-board and hybrid charging stations' cutting-edge topologies and looks in to each of its many subsystems, including Types, Classification, International Standards, etc. To create a low-cost and effective EV charging station, several components should be optimally connected and run. Additionally, each subsystem is thoroughly investigated to learn about its current condition and technological advancements. They also highlight challenges for both super charger stations. This paper presents an expanded and in-depth discussion of EV charging stations. This Study also discusses various charging technologies, types, architecture, improvements, and difficulties.
