The global transition towards electric mobility has created an urgent need for intelligent and efficient electric vehicle (EV) charging infrastructure. Conventional charging systems lack automation, remote monitoring capabilities, and the ability to interact with the power grid, leading to potential grid strain and inefficient energy consumption. This paper presents the design and simulation of a smart, automatic EV charging system leveraging the Internet of Things (IoT). The proposed system utilizes a NodeMCU (ESP8266) microcontroller as its core, integrated with voltage and current sensors to monitor the battery's state of charge (SoC). A relay module is employed to automatically control the charging process, preventing overcharging and enhancing battery longevity. The system communicates with an IoT cloud platform via the MQTT protocol, enabling users to remotely monitor real-time charging parameters and control the charging operation through a web-based dashboard. The complete system architecture, hardware, software logic, and simulation approach are detailed, demonstrating a cost-effective, reliable, and user-friendly solution for modern EV charging.
