Development of a Smart Portable IoT Enabled Electric Vehicle Charging Station

Electronics and Telecommunication Engineering

For electric vehicles, traveling range and charging infrastructure are the two major issues affecting its adoption over conventional vehicles. To overcome the issue its important to provide charging options at multiple places. But due to high initial investment and infrastructure needs it is difficult to provide multiple charging stations. Here low cost and compact EV charging station will help to establish EV utilization. In this system, current sensor and voltage sensor are used to measure the power delivered to charge the vehicle. Both sensors will send signal to microcontroller. Microcontroller will calculate and measure the billing amount and display it. With the keypad and display user can set charging time or billing amount. Once the set value crosses, microcontroller will switch off the supply using cut off device. Microcontroller will send values and alert to the webpage through Wi-Fi module. Buzzer is used to provide audio signal. Power supply will provide the required power to every circuit element. Proposed system will provide 230V AC output for EV charging with power meter. This makes proposed system compatible with every vehicle charger so that every vehicle can be charged.
