Aim

There is a large and growing need in the automotive industry for engineers with specialisation in electrical drives, power electronics and not least system aspects of electric vehicle control. This course has the ambition to give fundamental knowledge and skills in these areas.

Learning outcomes

Knowledge and understanding
For a passing grade the student must

• have good general knowledge of the design of a hybrid vehicle and the characteristics of the most important components of it,
• have good general knowledge of the composition of the drive line and the control of the energy flow in hybrid vehicle drive systems.,
• have good general knowledge of the energy supply system for a totally electrified transport system.

Competences and skills
For a passing grade the student must

• have developed the ability of choosing the most suitable drive line for a hybrid or electric vehicle for a certain range of application and of creating control strategies for it,
• have developed the ability of judging various solutions for drive systems and loading in relation to the energy supply system.

Judgement and approach
For a passing grade the student must

• have gained the self confidence to be able to model and analyze a electric vehicle drive and load systems.

Examination details

Grading scale: TH - (U, 3, 4, 5) - (Fail, Three, Four, Five)
Assessment: Passed simulation assignments give the grade of 3. For higher grades, an approved written exam is required.

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
