Fault Diagnosis Technology of New Energy Vehicles is the core course of new energy vehicle technology specialty in higher vocational colleges, which accurately meets the professional ability requirements of front-line positions such as fault detection, after-sales maintenance and operation and maintenance support of new energy vehicles. The course is mainly aimed at professional students, front-line technicians of auto repair enterprises and technical enthusiasts in the industry. The core goal is to help students lay a solid foundation of professional theory, master the core practical skills of multi-scenario fault diagnosis and maintenance, and build the core competitiveness of professional practitioners through a systematic post-based teaching system. The course builds a full-chain teaching system from shallow to deep, with seven core teaching items, covering key modules such as basic knowledge of fault diagnosis, high-voltage insulation detection, intelligent key and one-button start-up system maintenance, and fault diagnosis of power battery system. Teaching follows the cognitive law of vocational education, starting with basic circuit knowledge and high-voltage safety standards, and gradually transitions to advanced training such as vehicle electronic control fault diagnosis and troubleshooting, and builds a gradient vocational ability training ladder to meet the needs of hierarchical teaching and skill improvement. This course has a solid foundation for teaching reform, and the course team has been deeply involved in the teaching reform of vocational education for a long time, and has taken the lead in participating in many provincial and municipal teaching reform topics, special courses on ideological and political education and pilot projects on the integration of on-the-job courses, competitions and certificates. Relying on the practice of teaching reform, the team continuously optimizes the teaching system, reconstructs the teaching content, innovates the teaching mode, improves the assessment criteria, transforms the teaching reform results into classroom teaching effectiveness, effectively breaks the teaching pain points such as the disconnection between theory and practice, and the disconnection between teaching and post requirements, so as to build a solid teaching and research support for the high-quality construction of the course. The course strictly meets the requirements of national teaching standards and vocational skill levels, takes the real work tasks of enterprises as the guidance, and constructs a teaching mode of "project leading, ability progressive, post-class integration, and educational reform empowerment". The whole teaching process integrates the ideological and political elements of the course, cultivates students' craftsman spirit, safety awareness and feelings of industry serving the country, and simultaneously consolidates professional skills and professionalism. The course has built three-dimensional digital teaching resources such as micro-courses, two-dimensional animations, training worksheets, question banks, etc., and implemented online and offline mixed teaching, relying on the training bases inside and outside the school to carry out theoretical and practical progressive training, so as to realize the seamless connection between the teaching content and the post requirements of enterprises.
