An Investigation into the Technical Feasibility of Incorporating Wind Energy for Electric Vehicle Charging Systems

Abstract

The primary objective of this research project was to investigate the potential application of wind energy as a solution for reducing charging time and extending the driving range of electric vehicles (EVs). To harness the benefits of the aerodynamic characteristics around the vehicle, a vertical-axis wind turbine was designed and positioned beneath the vehicle, with an inlet located at the front grille. The turbine blades were designed using the NACA4415 airfoil profile and fabricated using 3D printing technology. Experimental measurements were conducted in a subsonic wind tunnel to evaluate the velocity-to-voltage relationship. The experimental results revealed a significant increase in speeds, reaching up to 50% improvement when a nozzle was incorporated into the system. However, at a wind speed of 11.14 m/s, the speed increment dropped to 10% due to wind speed instability. At lower wind speeds of 12 m/s, the power output was measured at 11.28 W, which is considered relatively low. The utilization of a nozzle at the turbine inlet successfully enhanced the wind velocity, resulting in a power output increase of up to 19 kW. The highest recorded wind velocity was 33.33 m/s. Consequently, the integration of a nozzle at the inlet of the wind turbine demonstrated its potential to provide a greater supply of wind energy, thereby generating higher power output within the EV system.
