With the rapid development of the new energy vehicle (NEV) industry, vocational colleges have an increasing demand for teaching on NEV electrical system fault diagnosis. This article provides an in-depth analysis of the current situation of NEV electrical system teaching in vocational colleges, including the characteristics of student learning, as well as pain points such as insufficient hardware equipment, lagging enterprise case updates, and a single evaluation system in the teaching process. Based on this, it proposes teaching practice strategies such as the integration of theory and practice teaching mode innovation, smart classroom technology empowerment, and safety norms and professional ethics cultivation. A specific analysis is conducted through the case of Geely EV450 high-voltage interlock fault maintenance, aiming to provide useful reference and lessons for vocational colleges' NEV electrical system fault diagnosis teaching, improve teaching quality, and cultivate high-quality technical and skilled talents that meet industry needs.
