Abstract
For sustainable electrification of surface transportation, a viable charging infrastructure is necessary. Firstly, this paper focuses on emphasizing the viability of a free fuel-based photovoltaics and/or wind turbines and lithium-ion battery-based power network to enable sustainable electric power. The importance of power electronics for a DC-based power network and extremely fast charger based on DC power is presented. Finally, the core design concepts of intelligent charging infrastructure using an intelligent energy management system are discussed. The paper aims to cover all aspects associated with a clean, reliable, efficient, and cost-effective solution to the novel charging infrastructure.
Highlights
Other than the COVID-19 pandemic, the increased risks to the world due to climate change have become one of the most dominant issues today
A complete direct current (DC)-based system is the most efficient implementation strategy taking into consideration the technical and economic requirements of the charging infrastructure
With a complete end-to-end DC network, we can eliminate the power losses incurred in the existing infrastructure and reduce the ultimate charging cost of EVs
Summary
Other than the COVID-19 pandemic, the increased risks to the world due to climate change have become one of the most dominant issues today. The strain in the current grid infrastructure can be minimized by adopting a novel sustainable power network dedicated for the EV charging framework In this scenario, the power factor control is not necessary as there will be no involvement of reactive power as discussed in the later sections of this paper. Apart from fast charging infrastructure, only charging EV at night schedules for residential customers has a significant impact on the grid In developing countries such as South Africa, due to lack of renewable energy penetration in the grid, the EV charging nighttime demand can generate a greater carbon footprint compared to an internal combustion engine (ICE) vehicle [20].
