Development of a BLDC Motor Drive System Powered by Battery-Supercapacitor Hybrid Storage and Solar PV for Electric Vehicle Applications

Abstract - This project presents the design and development of a Battery and Super-capacitor Fed Brushless DC (BLDC) Motor Drive System tailored for Electric Vehicle (EV) applications. The objective is to enhance the efficiency, dynamic performance, and reliability of EV powertrains by integrating a hybrid energy storage system comprising a battery and a super-capacitor. In this setup, the battery serves as the primary energy source, providing steady power during normal driving conditions, while the super-capacitor assists in handling transient load demands, such as rapid acceleration or hill climbing, and also absorbs energy during regenerative braking. This hybrid approach reduces stress on the battery, extends its lifespan, and improves overall system responsiveness. To further enhance energy utilization, the system can be integrated with a solar photovoltaic (PV) source, regulated using a Maximum Power Point Tracking (MPPT) algorithm. The MPPT controller ensures that the PV panel operates at its optimal power point under varying solar irradiance conditions, contributing to battery charging and reducing dependency on grid power.
