Research on Teaching Methods of New Energy Vehicle Technology Major Courses for Vocational Education Undergraduates

The development of new quality productivity in the new energy vehicle industry will help promote the upgrading of the new energy vehicle industry, stimulate technological innovation to improve the functions, performance, and quality of the vehicle, and maintain an advantageous position in the fierce market competition.Cultivating professional talents is the key to maximizing the development of new quality productivity in the new energy automobile industry.The core courses of new energy vehicle technology majors such as "Electric Vehicle Comprehensive Performance Detection and Evaluation", "Drive Motor and Its Control Technology", and "New Energy Vehicle Design" involve mechanics, electronics, electromagnetism, electrochemistry, and mathematics.These courses have many concepts, relatively abstract principles, multiple dimensions of performance curve analysis, and complex index evaluations.It is difficult for the traditional teaching model to achieve the purpose of enabling students to master theoretical and practical knowledge at the same time.Through the course construction and teaching of the above courses, an iterative method of concretization and dataization is proposed.First, the complex working principles are concretized to assist students in understanding.On the basis of concretization, the practical evaluation which links the target performance of automobile development process and the actual performance of the vehicle is proposed, and the concrete principle knowledge involved in design and development is turned into data, and the performance test curve and performance curve are combined through performance test experiments to comprehensively improve students' familiarity with
