---------------------------------------------------------------------***--------------------------------------------------------------------Although EV’s are very efficient in nature they do have a glaring problem in them. Even the state-of-the-art explore the design of a six-seater commuter vehicle electric vehicle with modern charging technology and aimed to be a cost-effective solution for urban residential Level 3 charging systems, also known as Fast DC-DC complex and campus settings. The study focused on charging systems, take about 8 hours. One commonly developing concepts for tubular chassis design and overlooked parameter is aerodynamics for a multi structural integrity, selecting appropriate electrical and seater vehicle. Due to their blocky designs the drag electronic components, and understanding the coefficient is significantly higher compared to other 4fundamental mechanisms of the steering system, seater EV’s. This parameter indirectly affects the range powertrain, and suspension. Additionally, a basic airflow of the vehicle further affecting the efficiency of the simulation was performed to visualize the path of air vehicle. A flow study would ensure uniform airflow through the vehicle, along with structural tests to assess distribution across the body. Uniform flow would also the chassis performance under heavy loading conditions. help analyze thermal flow behavior as it would directly These tests for structural analysis and stress impact the battery cooling and cabin ventilation. distributions were performed on ANSYS, while the flow 1.2 Problem Statement simulation was performed on SOLIDWORKS.
