Hybrid energy storage system improved energy efficiency in electric vehicles, suggesting better battery life and power delivery.
Electric vehicles (EVs) face challenges in achieving optimal energy efficiency, prolonged battery life, and enhanced power delivery for high-performance applications. To address these issues, this project proposes a Battery-Super capacitor Hybrid Energy Storage System (HESS) integrated with a bidirectional DC-DC converter. The system utilizes a battery for steady energy supply and a super capacitor for high-power transient demands, ensuring better energy management, reduced battery stress, and improved overall efficiency. The ATmega328 microcontroller monitors voltage levels, controls power flow, and optimizes energy distribution. The system also includes MOSFET driver circuits, a voltage sensor, and an LCD display for realtime monitoring. This approach enhances energy utilization, increases the lifespan of the battery, and provides a more sustainable solution for electric vehicle power management.
