Aims:

To provide comprehensive understanding and hands-on experience with the physical, chemical and electronic characterisation techniques essential to the electric powertrain.

Synopsis:

The world is at the transition from conventional fossil fuel-based piston engine technology to the electrification of transport and use of sustainable fuels. To enable this transition, an in-depth understanding of electrochemical and electronic processes in materials, packs and vehicles is needed. This module covers the theoretical and experimental aspects of advanced characterisation techniques needed to traverse the vast range of length scales relevant to advanced propulsion. This will include state-of-the-art physical, chemical and electrical probes and their correlative application to materials, cells, packs and vehicles.

SYLLABUS

1. Physical and Chemical – microscopy, X-ray diffraction/scattering, X-ray computed tomography, neutron, Raman spectroscopies, mechanical test, nanoindentation;
2. Electrochemical – electrochemistry (CV, charge/discharge, GITT, PITT), impedance spectroscopy;
3. Electronic – power electronics characterisation, circuit theory;
4. In-situ/operando – including acoustic, thermal techniques; 5. Vehicular – dynometers, large-scale diagnostics (off-board and on-board).

Learning outcomes:

Upon completion of this module, the students will be able to:

1. Comprehensively describe different characterisation tools and analyse their relevance to advanced propulsion technologies;
2. Systematically apply theoretical principles of characterisation techniques to design and conduct high-quality experiments and/or simulations;
3. Connect to current research topics in propulsion and electrochemical engineering (connected curriculum) through practical examples in class, guest lecturers, project-based research andinteractions with researchers;
4. Communicate their understanding of the underlying theory and their findings at a high standard similar to that expected for conference presentations.
