Abstract: New Energy Vehicle Maintenance and Fault Diagnosis is the core course of higher vocational new energy vehicle technology. Traditional teaching methods face challenges such as a disconnection between teaching tasks and real job responsibilities, low levels of student engagement, and insufficient assessments of learning outcomes. This study integrates project-based learning (PjBL) theory and the Countenance Stake model to design STEM-based tasks and a multi-faceted evaluation system. Enhancement of students' practical competencies, problem-solving skills, and professional attributes is demonstrated through project-based teaching, with insights provided for adaptation to new energy vehicle technology reforms in vocational education.
