Abstract: In response to issues such as the relatively backward training of NEV teaching personnel in vocational education, insufficient practical training for students, and hidden safety hazards in practical operation, a “five-in-one” intelligent practical teaching system has been established. Based on traditional classroom teaching supplemented by cloud classroom independent learning, the system focuses on virtual simulation training and real and practical training, supported by an intelligent assessment and evaluation system. By combining curricular and extracurricular activities, virtual and real content, software and hardware, and by advancing level by level, this five-in-one system is able to inspire students’ learning enthusiasm and improve students’ practical skills. In practice, the practical teaching system has also achieved the goal of training innovative and practical NEV personnel with some encouraging results.
