The world is transiting from mechanical to electro-mechanical in the field of moving and dynamical systems.The key technologies like modern power electronics ,digital processor/controllers are enabling all this from static drives in industries to high power actuators in space or in house automation vacuum robotic system to high power electric vehicle for road transportation. Electric mobility is now becoming reality of near future. Vehicle manufacturers and policy makers are boosting their attention and actions related to electric vehicles(EVs).Now, there’s been a renewal of this technology, especially towards the end of the 20th century. To reduce the impact on the climate, the industry is experiencing a shift from internal combustion engine (ICE) vehicles to electric vehicles.
ICE-based vehicles operate on oil, an increasingly scarce resource that heavily pollutes the environment and is a major contributor to climate change.In addition to the direct incentives and measures to promote PHEVs & HEVs adoption, there are other factors that are reinforcing the transition to e−mobility. But there have been underlying roadblocks that have hampered the evolution into the new model, the most prominent ones being: range anxiety, the price of EV vehicles, and finally, the charging times of the batteries compared to filling the tank of a conventional vehicle. Range anxiety can be overcome by the development of hybrid electric vehicles (HEVs) and plug-in hybrids (PHEVs) vehicles. The other alternative is to replace it with higher energy density batteries.
The last remaining hurdle is the charging time, where slow (up to max 22kW effectively) and fast systems (22–400kW and targeting above) coexist. Slow charging systems are already relatively widely available in households, public parking, and workplace parking. However, fast-charging systems are mostly available publicly, in commercial areas, or in charging stations as they require dedicated electrical infrastructure.
At the highest power rating of slow charging, the systems can provide 100 km additional range in approximately 50−60 minutes, but even these cannot be deployed at households easily. At the lower power end, 1.4 –3.7kW rates are possible at households and privately when using a dedicated cable directly connected to the standard socket-outlet but take around 5 hours (at 3.7kW) to add 100 km of range.
On the contrary, fast-charging systems can deliver this range in less than 10-minutes. For a significant share of drivers and use cases, slow charging might be a feasible solution, but clearly, not for everyone or every situation.
