WM994-15 Electrical Drivetrains
Introductory description
30 hours over 4 weeks consisting of interactive presentations, question and answer sessions and discussion, online sessions, videos, small group exercises and problem classes.
The module includes a significant practical element (~30%) where students gain hands-on experience of electric machine design, switches characterisation and electric machine modeling and control.
Module aims
The purpose of the module is for the students to learn about advanced propulsion technologies for hybrid and electric vehicles. In particular, the learning is focused on electric machines, power electronics and control appropriate for hybrid and electric vehicles.

Assessment group A2
| Weighting | Study time | Eligible for self-certification | |
|---|---|---|---|
| Evaluation of technology application | 50% | 30 hours | Yes (extension) |
|
This part is related to discussing a typical electric machine configuration and their associated control and power electronics system. |
|||
| Electric machine performance and simulation - Group work | 20% | 12 hours | No |
|
The task consists in evaluating the performance and efficiency of different Electric Motors in the context of Hybrid/Battery Electric Vehicles using related software. Students are assessed by writing a group report based on the undertaken activities. This is a group task where students are divided into groups of 3 to 6 supported by a tutor. Peer review assessment methodology will be implemented in this assessment. |
|||
| Evaluation of practical activities - Group work | 30% | 18 hours | No |
|
This is a group task and consists in reporting the investigations of one of the practicals undertaken in the module. The group chooses which practical to report. Peer review assessment methodology will be implemented in this assessment. |
