This project focuses on designing a Bidirectional Power Converter for EV battery charging and management. The system enables both Grid-to-Vehicle (G2V) and Vehicle-to-Grid (V2G) power transfer using a simple power electronics topology. A PIC microcontroller governs the system, adjusting the output of the charger based on control signals. The microcontroller monitors key battery parameters, including State of Charge (SOC), State of Health (SOH), voltage, and temperature, displaying real-time data on an LCD module. To ensure battery safety and efficiency, the system integrates voltage sensors, a temperature sensor, and an automated cooling mechanism. If the battery voltage drops below 23V, the microcontroller activates a generator to recharge the battery. In case of overheating, a cooling fan is automatically triggered to regulate temperature. The embedded C-programmed microcontroller ensures seamless automation of these functions, enhancing battery life and energy efficiency.
