Abstract: The project aims to enhance the safety and authenticity of Electric Vehicle (EV) components by implementing a system that distinguishes authorized (original) and unauthorized (duplicate) products. Using the BQ2026 for identification and the ESP32 for control, the system verifies product authenticity via unique identification numbers. Authorized components activate the corresponding port's power supply via MOSFETs, while unauthorized ones trigger power cut-offs, display warnings, activate a buzzer, and send alerts through the Blynk app. This innovative approach ensures EV reliability, reduces counterfeit risks, and provides real-time notifications to users.
