Course abstract

The aim of the study course is to learn the diagnostics of electric drive vehicles as an essential part of the technical service of such vehicles. Students learn the structural features of electric vehicles, requirements and safety regulations in connection with the maintenance and diagnostics of such vehicles. Get acquainted with the technological process of diagnosing electric vehicles and their components and the equipment and methods used in the process. In laboratory work, students have the opportunity to practically carry out all components of the diagnostic process - diagnosis, determination of technical condition, forecasting of the remaining work resource.

Learning outcomes and their assessment

1. Knowledge - master's students acquire theoretical and practical knowledge, understanding of technical diagnostics of electric vehicles and related processes in service companies, safety standards, latest diagnostic methods and equipment. The acquired knowledge can serve as a basis for further creative and professional development. Assessment of knowledge - verification test.
2. Skills - master's students are able to creatively use the acquired knowledge in the field of electric vehicle diagnostics, are able to independently use theory, methods and problem-solving skills to perform research or highly qualified professional functions. The ability to evaluate and make decisions in difficult situations related to the topic of the study course. Assessment – review test and lab reports.
3. Competences - master's students are able to independently analyze complex scientific and professional problems, make reasonable decisions, and, if necessary, perform an in-depth analysis of problems. Able to integrate the knowledge of various fields in the improvement of professional activity and the development of new diagnostic methods. Competences are controlled with 2 examination tests, as well as laboratory works and their reports.

Requirements for awarding credit points

Assessment with a grade. All examination tests must be passed and laboratory work must be developed and passed.

Description of the organization and tasks of students’ independent work

Studying lecture materials, preparing for examination tests, processing, analyzing and graphically displaying data obtained in laboratory work, preparing laboratory work reports.

Criteria for Evaluating Learning Outcomes

The passing grade is made up of the average grade of the grades obtained in the examination tests and the grades of the defended laboratory works. A student can get a successful assessment on the test if at least 50% of the test questions are answered correctly.
