Automotive Powertrain Electrification Fundamentals (15 cr)

Introduction

The 21st century automotive industry is transitioning at pace to electric propulsion technology, presenting new challenges in component and system design and vehicle integration. This module provides a holistic introduction to electrified automotive powertrains, from global motivations through to component design. Existing approaches to partial and full electrification are critiqued and opportunities for new design and research opportunities are exposed. The module is delivered through a mix of traditional lectures, group discussion and design activities and hands-on practicals using both established and novel tools and techniques.

Principal module aim is to equip participants to constructively engage with automotive powertrain electrification programmes and technologies in their current or future engineering careers.

Objectives

Upon successful completion participants will be able to:

  • Independently critique global stakeholder influences, motivations and industry progress in automotive powertrain electrification
  • Comprehensively understand existing H/EV products, their relative merits and critique designs against practical real-world applications
  • Systematically derive power and energy requirements for automotive products in alignment with standardised evaluation criteria and real-world end-user requirements
  • Design and evaluate energy storage and electric machine technology as co-dependant sub-systems of vehicle powertrain applications
  • Critique a wide variety of approaches to energy management with regards to applicability, complexity, optimality, resource requirements and practicality
