The thesis
Micromobility vehicles, such as e-scooters and e-bikes, are shaping the future of urban transport. Their success depends not only on user adoption but also on how efficiently they use energy. Understanding and improving the energy efficiency of these vehicles is key to building sustainable, reliable, and cost-effective fleets.
YOUR MISSION
This thesis explores the energy efficiency of electric motors and controllers in micromobility vehicles. You will work hands-on to evaluate and optimise how power flows through our scooters and e-bikes — from battery to motor output. The results will provide a detailed understanding of how different operating conditions impact energy losses and overall efficiency. The project combines theory with real-world application:
- You will design experiments, build testing equipment, and analyse performance data to generate actionable insights.
- You will design and build a custom test rig to measure electrical power and simulate mechanical load across the full powertrain.
STUDENT PROFILE
We are looking for an electrical engineering student with an interest in:
- Electric motors and motor controllers.
- Power efficiency and relevant measurement techniques (mechanical and electric power).
- Real world application of measurement equipment.
- Hands-on skills and curiosity for hardware are highly valued, as this project blends lab work, prototyping, and analysis.
