Leading the way in new energy vehicle teaching equipment

Under the new situation, with the development of the times and society, environmental problems are becoming more and more prominent. In order to improve the problem of energy shortage, new energy vehicle technology has come into the public eye. In the process of development and innovation of the automobile industry, it is necessary not only to introduce a large number of technical talents, but also to inject a steady stream of power into the development of the automobile industry. At the same time, the emergence of new technologies also means the demand for new talents. At this time, it is necessary to effectively innovate the professional teaching model on the basis of school-enterprise cooperation. Therefore, this paper first proposes the main content that needs to be explored, and then, combined with the current situation, a scientific extension and innovation path is formulated in a targeted manner.

1 Problem statement

For schools, the main thing is to cultivate more practical and comprehensive talents for the society. It is necessary to base on the actual needs of the society for talents, so as to improve students' core literacy and enhance the corresponding professional skills. my country's new energy vehicles belong to an industry with a relatively fast development speed. It is necessary to continuously increase the demand for talents and improve the demand for professional technology based on the market [1]. In the process of practice, although most colleges and universities have made some innovations in teaching models, there are still some shortcomings and problems. On the one hand, they are not well based on the current development trend of automobile majors, and on the other hand, they do not fully meet students' needs for practical teaching activities and later employment. In view of this, how will the teaching mode of new energy vehicle technology major be innovated under the school-enterprise cooperation model? This has become the main content and problem that many scholars need to explore under the current situation.

2 Current situation

2.1 Changes in the development direction of the automobile industry

With the development trend of new energy vehicles, the number of people using new energy vehicles has also begun to increase continuously, so the demand for talents will also rise to an important level. my country is one of the major countries in automobile production. It is necessary to determine the development direction of the automobile industry on the basis of the market industry and improve the innovation of automobile technology. The use of school-enterprise cooperation has pointed out the way for the training direction of students, met the needs of automobile development, and improved the corresponding logical thinking ability [2]. Students can also analyze the development trend of the industry based on their own actual situation, recognize their own shortcomings, and formulate scientific solutions in a targeted manner.

2.2 Serious shortage of high-tech talents in the automobile industry

With the continuous improvement of people's living standards, the development of the automobile industry has also begun to show an increasing trend year by year. However, from a traditional perspective, most of the talents trained are traditional automobile talents, but there are still certain differences in the development of new energy vehicles in new industries [3].

2.3 The traditional school-enterprise cooperation model cannot adapt to the development of new energy vehicle majors

First, new energy vehicle companies have not actively participated in classroom teaching. From the current situation, most companies have not actively participated in school-enterprise cooperation, and some schools have only invested in teaching unilaterally, ignoring the practical part. Second, the construction system of school-enterprise cooperation is incomplete [4]. Not only can it not explore the current learning situation of students, but it is also difficult to achieve effective feedback on knowledge learning. Third, when implementing the construction of teaching methods, colleges and universities have ignored the development prospects and current production scale of new energy vehicles. Under such circumstances, it is easy to limit students' thinking and even difficult to meet the needs of innovative development.

3 Innovative paths for the teaching model of new energy vehicle technology major under the school-enterprise cooperation model

3.1 Innovation of the teaching model of new energy vehicle major under the school-enterprise cooperation situation

First, innovation in teaching methods. On the basis of school-enterprise cooperation, teachers also need to adhere to the main ideas of the scientific outlook on development, improve the main application of information technology, and continuously inject a steady stream of power into curriculum construction. Use segmented teaching methods to improve students' in-depth understanding ability and maintain innovation in teaching methods. We should not only pay attention to the current status of new energy vehicles, but also build an effective talent training strategy in line with the actual needs. Under an open vision, we should use information technology to enhance students' teamwork ability and maintain their understanding and absorption of professional knowledge [5]. We should make full use of teaching resources and organically combine colleges and enterprises to achieve the main purpose of practice and lay a good foundation for future development. For example, in the teaching process, teachers can guide students to think about "what is the core of new energy vehicles", and then use "energy" as the starting point to guide students to analyze what needs to be paid attention to in order for electric vehicles to have stronger endurance. At this time, students will explore each other, deepen the teaching content on the basis of problem-based teaching methods, and liven up the classroom atmosphere. Second, promote joint teaching between schools and enterprises. For colleges and universities, only by strengthening the relationship between schools and enterprises can we determine the direction of talent training in effective exploration, continuously improve the path of teaching and education reform, and improve the pertinence of goal construction. In cooperation, we can jointly compile professional teaching content so that students can flexibly master professional knowledge and skills, acquire work experience, and adapt to job needs while understanding the development needs of automobile enterprises [6]. Third, implement order training. Based on the needs of enterprises, we can increase the intensity of school-enterprise cooperation and issue corresponding teaching content and teaching tasks through orders to meet the needs of enterprises for talents. Colleges and universities also need to adapt to the development needs of the times and formulate scientific solutions according to the needs of positions. Create a process that conforms to the development of enterprises, ensure an effective technical route, and provide more high-quality talents for society.

3.2 Schools and enterprises need to jointly establish a learning and work platform

At this time, schools need to find dual-track practical training courses that can meet the development of new energy vehicles based on the principle of "school-enterprise cooperation and mutual benefit and win-win development" based on the needs of society and enterprises. In addition, it is necessary to combine the production status of enterprises, see the problems in teaching work, and organically combine enterprises and schools to achieve an efficient teaching model [7]. In addition, schools also need to guide students to master more automotive professional skills and develop from imitation to independent operation. There is a big difference between new energy vehicle technology and other jobs. It requires not only repairs but also maintenance. Compared with traditional cars, new energy vehicles require more patience and care. In the process of technical learning, the content is more complicated and more details are needed during operation. Therefore, in the process of implementing the teaching of new energy vehicle majors, it is necessary to combine schools and enterprises under a comprehensive vision to build a broader learning platform. For example: colleges and universities can build a 4S store based on their own actual situation, which is an integrated training room for repair and maintenance, as well as other accessories rooms and multi-functional conference rooms. Work-oriented, combining theory with practice. Finally, colleges and universities can also encourage students to actively participate in competitions, combine new energy vehicle testing and maintenance technology majors with some well-known enterprises, enhance the effect of practice, and master the development laws of the market. Teachers can also sublimate their own theoretical level in practice, learn more practical knowledge, and improve their hands-on practical ability. On the basis of comprehensive literacy, reasonably guide students, enhance the corresponding professional level, improve students' innovative thinking, so that students are equivalent to employment when they graduate, and can get a broader technical extension in enterprises.

3.3 Comprehensively implement the strategic policy of talent training

First, it is necessary to implement relevant policies and systems on the basis of school-enterprise cooperation to promote the common progress between the two. In real life, new energy vehicles belong to the trend of internationalization, and in different countries, the manufacturing standards for new energy vehicles are also different. Only by combining colleges and enterprises and improving the cooperation and communication between the two can the perfection and pertinence of the teaching plan be met. With the job ability as the orientation, establish real work tasks, explore the engine, improve the scientific construction of equipment, lay a solid foundation, and promote the integration of talent teaching mode. Recognize the shortcomings, increase the intensity of investigation, and build a corresponding curriculum system. Second, it is necessary to continuously optimize and improve the school-enterprise cooperation system. The construction of the system is mainly to enhance the work enthusiasm between enterprises and schools, increase communication construction, maintain the binding and management of the teaching plan, and reasonably guide schools and enterprises to actively participate in it, so as to meet the needs of modern development. From the perspective of enterprises, it is necessary to increase cooperation with schools, increase supervision, and let excellent enterprise talents go to the practice base to provide course guidance. In the long run, students can not only feel the atmosphere of actual production in the enterprise, but also recognize their own shortcomings in the process of practice and continuously enhance their comprehensive ability [8]. Schools also need to combine the actual needs and establish an effective reward and punishment system. Students with excellent performance need to be given maximum encouragement to enhance students' confidence in learning, so that students at different levels can improve their abilities to varying degrees.

3.4 Use innovative means to cultivate talents

The new energy vehicle technology major is not only a global development trend, but also a focus that needs to be explored under the current situation in my country. In the process of teaching and training students majoring in new energy vehicles, teachers need to adhere to the main ideas of the scientific outlook on development, use diversified innovative teaching methods, extend students' thinking logic, improve students' subjective initiative, enhance students' innovation ability, and meet students' personalized development needs. In addition, it is necessary to combine theory and practice with each other, guide students to form new innovative ideas in verification, promote the transformation of teaching models, and maintain the enthusiasm and initiative of teaching. Teachers also need to change the original teaching model, integrate teaching resources, and improve the subjective initiative of learning according to the actual situation and development laws of students. After that, students need to be given more training platforms, optimize themselves in practice, and enhance their hands-on operation ability in school-enterprise cooperation. The 2+2 teaching model is implemented to enable students to better understand the enterprise, maintain the matching of knowledge, skills and enterprise development, and make students better adaptable to the enterprise. The main innovative methods used are problem research, content analysis, practical exploration, project research, etc.

A brief discussion on the reform and exploration of practical teaching in the new energy vehicle major

As an environmentally friendly type of car, new energy vehicles are sought after by consumers. The manufacture of new energy vehicles is inseparable from the cultivation of professional talents. In practical teaching, it is necessary to clarify the type of training, constantly innovate teaching practice, and better cultivate comprehensive talents suitable for the development of the times.
1. Training objectives of new energy vehicle major teaching
In the teaching process of new energy vehicle major, it is necessary to clarify the direction of talent training. First of all, it is necessary to master the corresponding theoretical knowledge and technical level, and be able to play a role in practice, mainly in the automotive design industry, repair industry, manufacturing industry, etc. The research and development and design of new energy vehicles require the participation of professional talents. This process requires sufficient knowledge reserves and professional hands-on design capabilities, as well as the spirit of continuous innovation and development. In the process of training, the comprehensive quality of students should be cultivated in a multi-level and comprehensive manner. Students can master enough theoretical knowledge in learning, develop the ability of conscious exploration, have their own ideas in automobile manufacturing and design, and improve their hands-on ability and knowledge level through continuous practice. In addition, the manufacturing of new energy vehicles also requires students to master knowledge of automobile structure, automobile manufacturing, etc., and be familiar with computer, drawing and other skills. This requires combining the current teaching methods, continuous reform and innovation, and achieving the goal of talent training.
2. Reform of practical teaching of new energy vehicle major
2.1 Continuously optimize theoretical teaching
Theoretical knowledge has guiding significance, and the teaching of theoretical knowledge must not be ignored in practical teaching. In the teaching process, teachers need to guide students to master the corresponding physical principles, internal structure of automobiles, force analysis, electrical principles, electromechanical principles, etc., which contain many aspects of knowledge. Schools can combine reality and carry out more subjects to lay a solid foundation for students' theoretical learning. In classroom teaching, teachers should reasonably design teaching content, keep up with the demand for new energy vehicles in the development of the times, set up course teaching, and continuously optimize theoretical teaching, so that students can continuously improve their comprehensive abilities while mastering theoretical knowledge and solve various problems in new energy vehicles.
2.2 Continuously reform practical teaching
The knowledge of new energy vehicle majors is still practice, and practical teaching plays an important role in improving students' abilities. At present, the practical level of new energy vehicle professional teaching in my country is relatively small. This requires schools to make full use of social energy and resources through continuous reform, increase opportunities for practical learning, and allow students to master skills and improve technology in practice. It is more common for schools to cooperate with enterprises, and students have ample opportunities to combine theoretical knowledge with practice, check for omissions and make up for deficiencies in practice, and better improve their knowledge level and technical capabilities. In addition, in the teaching process, we must also recognize the gap between laboratory teaching and real contact with new energy vehicles. Laboratory teaching is carried out to a certain extent and cannot completely replace practical teaching. In addition, the equipment in the school laboratory may not be updated in time, and the teaching management cannot keep up with the development of the times. In this way, it is difficult for laboratory teaching to achieve a real qualitative leap. Therefore, it is necessary to continuously reform practical teaching, so that students can improve their innovation awareness, design ability, etc. in practice, and become new energy vehicle professionals with strong comprehensive abilities.
2.3 Update teaching equipment in a timely manner
The main research object of the new energy vehicle major is new energy vehicles. When purchasing equipment, schools should start with new energy vehicles appearing on the market, purchase the latest models, guide students to study and research, and have a comprehensive understanding of new products and new technologies. It is mainly manifested in the aspects of automobile fuel, control system, motion system, etc., combining theory with practice, mastering core skills, and improving one's own ability. Schools should update equipment according to their own capabilities, and can purchase and apply it by themselves or in cooperation with enterprises. In practical teaching, teachers with strong professional knowledge should be guided, so that students can have a more comprehensive and accurate understanding of new energy vehicles under the guidance of teachers, and such learning will be more professional and scientific. The teaching methods of the course are also diverse. It can be taught by combining traditional teaching methods with new methods. There are multiple new teaching methods. Teachers can guide students to discuss in groups, explore the principles of new energy vehicles, arrange practice flexibly, and explore and solve problems in time, improve students' learning enthusiasm and passion, and let students truly master hands-on ability, innovation ability, practical ability, etc. in learning. The innovation of teaching equipment must keep up with the times. As a commodity that is frequently updated, if new energy vehicles are not combined with the development of the times in practical teaching, it is easy to cause the knowledge learned to be unused or eliminated. Therefore, it is necessary to update equipment and knowledge systems in time to better realize teaching that keeps pace with the times.
3. Conclusion
In summary, new energy vehicles are the development trend of the automobile industry under the new situation. The teaching of new energy vehicle majors needs to be paid attention to. In order to cultivate comprehensive talents with unified technical and theoretical knowledge, teachers need to continuously guide and lead in daily teaching. The school purchases high-quality equipment, establishes and improves a professional teaching team, and contacts enterprises to obtain more practical opportunities, so as to better cultivate students' professional ability and technical level, strive to cultivate talents who can adapt to the development of the times, let more talents flow into the market, and improve the manufacturing vitality of new energy vehicles in my country.
