Emerging Trends in Electrical Vehicle and its Charging Station

Abstract

With the increasing requirement in green technologies, Electric Vehicles have proven to be the best solution for transportation to reduce greenhouse gas emissions. The conventional electrical vehicle drivers are still reluctant in using such a new technology, mainly because of the time duration (4-8 hours) required to charge the electric vehicle batteries with the currently existing Level I and II charging station. For this reason, Level III fast- charging stations capable of reducing the charging duration to 10-15 minutes are being designed and developed. This paper focuses on the design of a fast-charging station for electric vehicle, in addition to the electrical grid, two stationary energy storage devices flywheel energy storage and a super capacitor is being used. Power electronic converters used for the interface of the energy sources with the charging stations are designed. The design development also focuses on the energy management that will minimize the battery charging time. Battery charging by solar power instead of Grid power brings new evolution in Electrical vehicle charging system. Installation of solar rooftop system on charging station will move one step ahead toward green energy in which Surplus power can be also fed to Grid by Net-metering.
