Recent Trends in EV Technologies, Charging Process and Standards: A Comprehensive Review

In this era, the depletion of fossil fuels and rising concerns about the emission of greenhouse gases (GHGs), which has contribution 30-40% of green-house-gas (GHG) emission by fossil-fuel operated transportation systems only and creating serious issues to environmental and eco-systems. So, there is a rapid transition toward electric vehicles (EVs) transportation system and it is providing a significant role in ongoing and coming electric vehicle transportation system. It has a significant scope for new research and advancements. Electric vehicles do not produce any kind of pollution i.e. emission of gases, noise pollution and running economically. The electric vehicles (EVs) have exponential growth and recognized worldwide. The rapid growth of electric vehicles are facing different challenges i.e. technical advancement, charging infrastructures, distribution network bidirectional power flow and charging time. This paper comprises a vital review on infrastructure of EV, latest scenario in technical development, different electric vehicles, AC-DC chargers with different charging standards, AC-DC isolated and non-isolated converters details. Slow and fast chargers and their levels of charging power and connectors are to be analysed for improving charging methods. There will be some challenges and future scopes for further advancements in modern electric vehicle technology.
