Challenges in EV and HEV Driveline Designs

Presented by: Chris Halse, Head of Engineering Services, Romax Technology
Whilst design practices for electric motors and design practices for gearboxes, such as those used in typical EV and HEV vehicles, are well-established, problems associated with the integration of the different components have been encountered in the development of EV drive units.
In particular, reducing noise from gearboxes and motors to an acceptable level in EV systems has resulted in expensive delays in development.
There is a very fast-pace demanded of design and development engineers for these new systems, and so problems late in the development process must be avoided.
In this webinar we will outline our understanding of the challenges in development of EV and HEV drive units and hybrid transmissions, and introduce the tool chain we recommend.
- Architecture design
- Optimising for maximum efficiency over realistic drive cycles
- Noise environment
- Lack of masking noise from Internal Combustion Engine
- Motor and gearbox sources of vibration
- Requiring multi-physics electro-magnetic and mechanical simulation
- High rotor speeds
- Predicting response to vibration at higher speeds
- Maximising efficiency
- Gaining every percent from mechanical system design
