Design of Wiring Harness and Performance Analysis of Powertrain Using Matlab and E-Cad for Electric Vehicle

In this work, we aim to design the electrical harness of an electric vehicle, which serves as the crucial network that connects all components within the vehicle. The primary objective is to ensure that the harness is designed to optimize cost, serviceability, and safety during vehicle operation. To achieve this, we use AutoCAD Electrical software, which allows for precise and systematic layout of the wiring harness. Designing a vehicle involves several complex calculations, including those related to fuel economy, vehicle dynamics, transmission configurations, motor sizing and its control strategies, motor performance mapping, and battery capacity sizing. These calculations are essential for ensuring optimal performance and efficiency. For accurate evaluation, we employ Excel spreadsheets to carry out powertrain sizing calculations. This process helps in identifying the required capacity of both the battery pack and the motor suitable for the vehicle. Additionally, we utilize MATLAB Simulink software to simulate and analyze the electric vehicle's overall performance. By integrating these tools, we can evaluate the system's efficiency and functionality during the design and testing stages. This method allows us to make necessary adjustments and optimize the vehicle's performance before moving to large-scale production, reducing the risks and costs associated with design errors.
