QR Based EV Bulk with Overcharge Protection and Prevention

The increasing adoption of Electric Vehicles (EVs) has highlighted the need for efficient and safe charging systems. One of the major challenges in EV charging infrastructure is preventing overcharging, which is leads to battery degradation, reduced lifespan, and potential safety hazards. Therefore, this paper presents a Quick Response (QR)-based EV bulk charging system integrated with overcharge protection and prevention mechanisms. A solar panel, an ATmega 328 microcontroller, a Node MCU, a battery, Liquid Crystal Display (LCD), and an IoT device are some of the components of this work. The proposed system utilizes QR code technology for easy identification and access control of charging stations, enabling seamless user interaction. The data gathered by the device is sent to users using an IoT, and it is monitored by the BLYNK app. The data is uploaded to the BLYNK app cloud database via the Node MCU module embedded inside the microcontroller. It also integrates advanced QR based charging algorithms and real-time battery monitoring to protect against overcharging, ensuring that the EV's battery is charged efficiently, safely, and within its optimal capacity. This system prevents overcharging, the system incorporates a smart charging algorithm that monitors the battery's charging state in real-time.
