Abstract: Amidst growing concerns over the environmental impact of transportation, this study investigates the feasibility and practical efficiency of a Savonius-type wind turbine for energy recovery on low-speed mini electric vehicles (EVs). Mini EVs, typically operating in urban or restricted environments, represent an under-explored segment for such energy harvesting technologies. This study combined Computational Fluid Dynamics (CFD) simulations using ANSYS software for aerodynamic analysis and Matlab for power output estimation, with experimental validation on a custom-built mini EV platform. The Savonius turbine, designed for a target output of 50W at a 6 m/s wind speed, was fabricated using 3D printing. Simulation results indicated a potential maximum power output of approximately 50W and an operational range of 20-30W at turbine tip speeds of 2.5 m/s to 4.5 m/s. Experimental trials yielded a maximum electrical power output of 20.48W at a turbine tip speed of 3.5 m/s, with Tip Speed Ratios (TSR) ranging from 0.5 to 0.61. While the experimental power output was lower than simulated predictions, primarily due to mechanical and electromagnetic losses. The study successfully demonstrates the viability of deploying Savonius wind turbines for auxiliary energy recovery on mini EVs, offering a novel approach to enhancing their energy sustainability.
