Module summary

This module provides comprehensive knowledge of Electric and hybrid vehicle technologies, including aspects of energy storage, driveline, transmission, powertrain, clutches, differential and brakes.

Objectives

On completion of this module, students will be able to:
1. Describe the components and systems which combine to produce a modern automotive drivetrain for electric, hybrid and internal combustion vehicles;
2. Apply the principles of engineering science to the design and analysis of the above systems and components;
3. Demonstrate a detailed knowledge of the operating characteristics of key elements of the drivetrain;
4. Explore alternative approaches to the dynamic modelling of a drivetrain;
5. Evaluate performance and refinement characteristics of alternative drivetrains.

Learning outcomes
On successful completion of the module students will have demonstrated the following learning outcomes :
1. Demonstrate an in-depth knowledge and understanding of the design and function of the main components and mechanisms found within an automotive drivetrains.
2. Demonstrate understanding of concept and system design and differences in drivetrain for electric, hybrid and internal combustion propelled vehicles.
3. Evaluate critically and demonstrate an awareness of the link between system performance, energy requirement, sustainability, maintenance, recycling and customer expectations that together drive the process of system development and integration.
4. Select appropriate components from catalogues with which to develop an electric or hybrid drivetrain unit capable of meeting a given specification.
5. Undertake the design of selected components within a drivetrain system taking into consideration aspects of energy storage, prime mover, load, stress, system performance, materials and operating conditions, demonstrate analytical and problem solving skills.
6. Apply scientific principles and modelling methods to the detail design of the power transmission elements for steady state and dynamic load cases to provide an assessment of durability and understanding of methods limitation.

Upon successful completion of this module the following Engineering Council Accreditation of Higher Education Programmes (AHEP) learning outcome descriptors (fourth edition) are satisfied:
7. Apply a comprehensive knowledge of mathematics, statistics, natural science and engineering principles to the solution of complex problems. Much of the knowledge will be at the forefront of the particular subject of study and informed by a critical awareness of new developments and the wider context of engineering. (M1)
8. Design solutions for complex problems that evidence some originality and meet a combination of societal, user, business and customer needs as appropriate. This will involve consideration of applicable health and safety, diversity, inclusion, cultural, societal, environmental and commercial matters, codes of practice and industry standards. (M5)
9. Evaluate the environmental and societal impact of solutions to complex problems (to include the entire life-cycle of a product or process) and minimise adverse impacts. (M7)

Skills Learning Outcomes

On successful completion of the module students will have demonstrated the following skills learning outcomes:

10. Problem solving & analytical skills, Managing Uncertainty, Ambiguity and Risk, Information searching, Computer Aided Design Design for manufacture
