The New Energy Vehicle (NEV) E-Powertrain Development and Training Platform is an advanced educational and R&D solution designed for vocational colleges, undergraduate universities, and automotive technology research institutes. It integrates the core "E-Powertrain" of a new energy vehicle—the power battery system, the drive motor system, and the vehicle control system—onto a single open, safe, and visual platform. This platform is engineered to provide students and engineers with a deep understanding of the internal structure, operating principles, and control strategies of electric vehicles, while offering a hands-on environment for fault diagnosis, software development, and performance testing.
