Research And Development Of Course "Battery And Management System Maintenance Of Pure Electric Vehicle" In Secondary Vocational School

In recent years,oil resources are scarce and expensive.In order to protect the environment and save resources and costs,countries around the world focus on the development of new energy automobile industry.China has also actively responded to the call of all countries in the world,and is also striving to develop new energy vehicles.Combined with China's national conditions,China has set its foothold on pure electric vehicles.In recent years,the production and sales of electric vehicles in China have continued to grow.According to the website of the Central People's Government of the people '.In addition,since November 2019,the production and sales of new energy vehicles have gradually recovered to the average level before the decline of subsidies,showing signs of improvement.In the first half of 2019,491000 pure electric vehicles and 126000 plug-in hybrid vehicles were sold.Moreover,in the whole year of 2019,electric vehicle sales in China accounted for 53.3% of global sales.With the rapid development of electric vehicles,the demand for technicians in this industry is also increasing.The biggest gap is the after-sales service personnel,such as charging pile installation and maintenance personnel,vehicle repair and maintenance personnel,etc.Since the market demand for electric vehicle related technical personnel is very large,the need for high-quality vocational education of pure electric vehicle is particularly prominent.At present,the vocational education in China basically adheres to the teaching idea of "learning by doing" and "learning by doing",combines "work standard" with "school standard",and uses modern apprenticeship system to guide vocational education.However,things are always unsatisfactory.At present,there are still many problems in Vocational Education under the modern apprenticeship system.For example,the top professional construction is not perfect,the curriculum system is not scientific,the teaching method is too old,there is no high-quality teaching content,the uniqueness of teachers and so on.This paper studies the curriculum development of the course "battery and management system maintenance of pure electric vehicle" in secondary vocational school,and tries to connect the integrated education of school management and practice with enterprise production in a real and close way based on the work task and the work process.First of all,through investigation,interview and other methods to investigate new energy vehicle enterprises and secondary vocational schools,carry out practical expert interviews to confirm typical work tasks;then through school enterprise cooperation,invite experts in new energy vehicle industry and vocational education curriculum development to refine the field of action,build the curriculum system and develop talent training programs;Then according to the relevant requirements of the top-level design,the specific teaching resources of the course "battery and management system maintenance of pure electric vehicles" are developed,including student manual,task work order,teaching design,teaching courseware,etc.;finally,through the teaching experiment method,a set of courses designed and developed in this paper are carried out in secondary vocational schools for teaching experiment,and the teaching effect,advantages and disadvantages of the courses are studied Office.Through the questionnaire survey,it is found that the effect of "battery and management system maintenance of pure electric vehicle" developed in this paper is quite satisfactory in the experimental school.
