EV charging infrastruture "The senerio"

Electic vehicles are now becoming the center of attraction of all the automobile companies and for the customers too as it is green and efficient and as well as provide a good amount of power and speed. With every plug-in vehicle sold requires a means of charging the vehicle. The E.V charging infrastructure is certainly a need for all of the electric vehicle out there. The majority of charging lot is installed at the resident and while the underlying electrical infrastructure largely in place, the hardware requires to plug-in cars into that infrastructure to charge simply does not exist in many places today.
But apart from the charging station infrastructure, there are many obstacles like the range(although it is improved by Tesla and other major car companies) but the charging speed and the cost related to installing a fast charging level 3 DC charging is very high.
Plug-in charging speed and infrastructure cost
An understanding of a plug-in vehicle charging speed is very crucial to understand the role of electric vehicle service equipment (EVSE's) which will play the transition to mass production.
Charging speed are split into three official level of charging as detailed in the SAE charging configuration and rating terminology document.

According to the U.S Department of energy, the cost of a single port EVSE unit ranges from $300-$1,500 for Level 1, for Level 2 it is $400-$6,500, and $10,000-$40,000 for DC fast charging. Installation costs vary greatly from site to site with a ballpark cost range of $0-$3,000 for Level 1, for Level 2 $600-$12,700, and $4,000-$51,000 for DC fast charging. There are many factors lead to a highly variable cost of EVSE's.
Though the level 3 DC charging needs less than 10 min. to charge the vehicle from 0% to 80% but comes with a very high cost of installation, and level 1 and 2 takes 3 to 17 hours of charging time. So once the charge of the vehicle is totally consumed, one has to wait at least for 3 hours to go again. Yes, there are challenges to overcome the difficulties of EV still like installing sufficient amount of charging booths for smooth run of EV's.
So further, we look into the alternative ways of EVs which don't need to plug in it a wall socket.
