Testing of Electric Vehicles

Course developers

Course abstract

The aim of the study course is to acquire the properties and their impact on electric vehicle operation as well as calculation of different automobile units and systems. The knowledge is sequentially supplemented by laboratory work that is carried out in laboratories and road condition tests.

Learning outcomes and their assessment

1. Knowledge - a master student obtains extended theoretical and practical knowledge, an understanding of the exploitation characteristics of electric vehicle that correspond to the latest achievements of science. Knows methods of calculation of main parts of vehicles - Test 1.
2. Skills - a master student is able to use the knowledge obtained in the theory of exploitation of electric vehicle in a creative way while conducting experimental studies and performing calculations to compare, assess, and analyse various vehicles. A master student is able to convincingly explain and discuss complicated topical issues concerning the theory of vehicles. Knows the test methods for conventional fuels and alternative energy vehicles - Test 2.
3. Competence - a master student can independently and critically analyse complicated engineering problems in the theory of vehicles, justify the decisions made, integrate the knowledge of this course with that obtained in other fields and courses to develop a methodology and process data to determine various parameters for the exploitation characteristics of automobiles. Ability to determine analytical and experimental parameters of vehicle operation - laboratory and practical work.
