Design and Implementation of Common EV Charging Station

Abstract

All people around the world requires to move from one place to another for their daily needs. To overcome this requirement conventional vehicles were developed. These vehicles run only by the means of fossil fuels such as petrol, diesel, gas etc. By consuming these fuels, they will exhaust CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> as their biproduct which causes global warming, release of greenhouse gas and other harmful effects. This leads to the invention of the Electric Vehicles (EV). This E-vehicles consumes only the electricity to run, and it does not require any lubricants and fuels. The main drawback of the Electric vehicles is the running time is limited due to the less amount of range in a charge. Electric vehicle charging stations are fewer compared to the petrol/diesel bunk at present. One of the main challenges for the electric vehicle is charging their vehicles in the charging stations and it involves added construction cost and requires lots of space while constructing a charging station for an individual battery voltage type. In a rare case if an Electric vehicle charging station is spotted, it may not be available for the all the type of electric vehicle models, it might vary according to the company models availability. This leads the driver to look for other charging station or upcoming charging station and there is huge demand on the particular or selective charging station. To overcome this situation, this study has built a prototype to enhance all the electric vehicle two-wheelers to charge their vehicles in a single charging station. The proposed model can charge the two-wheelers, which has their input voltages as 52V, 60V, 72V volts. These three voltages are selected based on the trending Electric Vehicles (EVs). 52V represent the Ather 450x model, 60V represent the TVS Iqube model, and 72V represent the Hero Photon model. To develop a feasible solution, this study has used the multi tap changing transformer to control these three-output voltage to the vehicle, which can be easily charged. Further, this study has created a mobile application to check the battery status and display the battery percentage while charging and time left for charging. This application can change the required input voltage at the time of charging. In addition to, this research work has implemented a special feature, which is auto cut off, which shutdowns the supply when the vehicles battery is fully charged. This avoids the critical situation of bursting of batteries when they are overloaded. This special feature is a feather in hat in our prototype. There are many advantages in using this type of charging station like charging the electric vehicle batteries, which contain different voltages such as 52, 60, 72 Volts, auto cut-off process is implemented and mobile application is used to switch the required voltages. The only demerit while using this system is the proposed model cannot be able to charge more than one vehicle at a time.
