Course purpose

TME095 covers hybrid and electric vehicle fundamentals and leverages simulation tools (Matlab+Simulink) to understand design choices and tradeoffs that affect the performance and efficiency of electric and hybrid-electric vehicle powertrains. Through the projects, lectures, and work required to pass this course you should learn:

― To identify the pros and cons of different types of hybrid powertrains
― The strengths and trade-offs of electric and conventional powertrains
― Approaches for optimal sizing of the electric machine, battery and combustion engine components
― Basic control approaches for a hybrid powertrain
― To simulate a hybrid powertrain and its controller to inform vehicle design choices
― To analyze the cost-effectiveness of different types of hybrid powertrains

Course design

The course is structured around Matlab and Simulink exercises (assignments 1 & 2) and lectures covering essential topics for making design decisions for hybrid and electric vehicle powertrains, primarily from the standpoint of efficiency and fuel consumption.

Assignment 1 is graded pass/fail, and passing the first assignment is required to begin the second assignment.

Assignment 2 is done in a group of 3, where you will develop several related powertrain models (conventional, hybrid series, & hybrid parallel). Each group will produce a technical report describing the models and analysis comparing the model performance of each design. Passing assignment 2 requires demonstration of a working series model and a working parallel model for your assigned vehicle class.

 

Learning objectives and syllabus

Learning objectives:

- describe the components of an arbitrary powertrain (combustion engine - gearbox,-electric motor - battery, or combinations of these (hybrid electric)
- derive a model of a battery suitable for a vehicle
- explain the advantages and disadvantages of a given powertrain
- derive a control strategy for a specified powertrain and driving scenario
- explain the influence of powertrain design and its control on powertrain efficiency

The course syllabus is available at Studieportalen: Study Plan

 

Examination form

All assignments are compulsory.

Assignment 1 is pass/fail; you must pass assignment 1 in order to start assignment 2.

The technical report for assignment 2 is graded (5/4/3/U), and counts 40% towards your final grade in the course

The course concludes with a comprehensive final exam, graded (5/4/3/U).

The course grade is based on the grades for Assignment 2 (40%) and the Final Exam (60%).
