high density energy
Our competence center operates to develop and concretize solutions concerning the switch to electric vehicles. Indeed, to keep them competitive compared to other energy sources (pneumatic, hydraulic, etc.), we focus on finding a way to increase the power density of electrical systems.
Moreover, the whole set of technologies and design methods needs to be revised to:
- increase the voltage to reduce the cable mass;
- use higher performance electronic components (wide gap components) to reduce losses;
- better integration of the components and equipment to master mass constraints, electromagnetic compatibility (CEM), network quality, reliability, thermal control, or costs.
Throughout our research, we concentrate on electromechanical conversion chains, electronic power converters, and electric motors, developing technologies (power modules, filters, inductances, printed circuit board, drivers, thermals, materials, etc.) and the methodologies required to optimize them (MDO/MDA) on different criteria (mass, thermal control, CEM, etc.). In other words, we aim at helping increase the power density of electronic circuits between 2 to over 10 kilowatts/kg and of electric machines between five to over 15 kilowatts/kg. In synthesis, we deal with voltages of less than a kilovolt for applications of a few hundred kilowatts (small carriers), but also with voltages of between 1 and 3 kilovolts for applications of over a million watts (propulsion, major carriers).
