This project presents a smart battery monitoring and management system utilizing a PIC microcontroller for efficient power regulation and real-time data transmission. The system comprises three batteries charged through a step-down transformer and a dedicated charging circuit managed by relays. Each battery is independently monitored using voltage and current sensors, and controlled via manual switches to allow selective battery usage and data acquisition.

A regulated power supply energizes the PIC microcontroller, which serves as the central processing unit, interfacing with various components including a temperature sensor, Wi-Fi module, LCD display, fan, LED indicators, buzzer, and other essential peripherals such as a reset button and crystal oscillator. The system collects and processes electrical and thermal parameters from the batteries, displaying critical data on the LCD and transmitting it to the cloud-based ThingSpeak platform for remote monitoring and analytics via Wi-Fi.

Additionally, the fan operation is governed by a transistor board, triggered based on sensor readings, ensuring thermal stability. This integrated approach not only ensures optimal battery performance but also provides predictive maintenance alerts, thereby enhancing the safety, reliability, and efficiency of battery-operated systems.
