Abstract
Regenerative braking systems (RBS) in hybrid vehicles have emerged as a pivotal technology to enhance energy efficiency by recovering kinetic energy during deceleration. This study presents an experimental investigation into the performance of regenerative braking in hybrid electric vehicles (HEVs), focusing on energy recovery efficiency, braking force characteristics, and impact on battery charging. The experimental setup included a scaled hybrid vehicle prototype equipped with a regenerative braking mechanism integrated with a battery management system. Key parameters such as braking torque, energy recuperation rate, and battery state of charge (SOC) were measured and analyzed. Results demonstrated an energy recovery efficiency of approximately 20-30% during typical urban driving cycles, indicating a significant contribution to overall vehicle energy savings. The study further discusses design considerations, challenges, and optimization strategies for RBS implementation in HEVs.
