Abstract — Simulink, a MATLAB-based graphical programming environment, is widely used for modeling and simulating electric vehicle (EV) systems. However, finding reliable, well-documented EV models for download can be challenging for students, researchers, and engineers. This paper provides a structured guide to locating suitable EV Simulink models, evaluating their quality, and effectively using them for simulation and design. 1. Introduction Electric vehicle development relies heavily on simulation to reduce prototyping costs and accelerate design cycles. Simulink excels at multi-domain modeling (electrical, mechanical, thermal), making it a standard tool for EV component and system-level simulation. While building a model from scratch is educational, downloading an existing model saves time—provided the user knows how to select and validate it. 2. Where to Download EV Simulink Models | Source | Typical Model Types | Quality | Documentation | |--------|---------------------|---------|----------------| | MathWorks File Exchange | Full EV reference models, battery, motor, DC-DC | High | Often excellent | | GitHub | Research-oriented, varying completeness | Variable | Check README | | MATLAB Central | User-contributed, some from MathWorks | Medium-High | Usually good | | University websites | Educational, simplified models | Medium | May be limited | | Commercial toolboxes (e.g., Powertrain Blockset) | Professional, validated | Very high | Full documentation |
