Design and development of a regenerative suspension system for electric vehicles

Abstract

This paper investigates the potential of regenerative suspension systems to enhance automotive efficiency and sustainability, particularly in the context of electric vehicles. By reducing inherent vibrations in suspension systems and recovering otherwise wasted energy, these technologies present promising opportunities to improve overall vehicle performance and safety. The study identifies mechanical motion conversion-based regenerative shock absorbers as a viable solution, emphasizing their operational efficiency and structural simplicity. Through simulation model evaluations, the research underscores the importance of methodological choices, with the quarter-car model and MATLAB/Simulink identified as optimal for balancing computational efficiency and parameter accuracy. Ultimately, this study highlights the pivotal role of suspension systems in modern automotive technology and underscores the value of regenerative solutions in advancing energy efficiency and sustainability in vehicles.
