The MOBeAT project:

schema electric drive train for two-wheeled

Electric vehicles are an important factor in achieving European climate targets. The change toward electric drives is clearly visible also in the two-wheeler sector, driven by regulations and subsidies, but also by the ever-growing acceptance among the public, which is beginning to recognize the benefits of electrically powered vehicles. Strongly increasing market shares are to be expected, especially in urban areas. The MOBeAT project partners, led by KTM as the OEM, know each other well from previous projects and have already built up expertise on electric drive trains. These are now to be bundled in a new project to create holistic simulation tools that will make it possible to model different drive concepts and technologies, as well as high-current winding concepts with high fill factors and integrated cooling. 

The simulation tools will be used to optimize these concepts with respect to multidimensional parameters such as efficiency and power density. Together with a modular power electronics approach, this should significantly save development time and costs. Different technologies such as gallium nitride semiconductors, metal 3D printing and generative heat sink optimization are included. The optimized system concepts go beyond the state of the art and are to be validated and compared with each other using two different inverter demonstrators on the test bench and in a two-wheeled vehicle. Finally, the data evaluation towards the end of the project will be used to improve the simulation models.
