At the end of 2019, the European Commission presented “The European Green Deal”, with the aim of transforming the European Union into a modern, resource-efficient and competitive economy. The most important objectives thereby are the reduction to zero net greenhouse gases emissions by 2050 and to ensure economic growth decoupled from resource use. HiEFFICIENT project – a Research and Innovation Action funded by the ECSEL Joint Undertaking – directly addresses these objectives targeted in the “The European Green Deal”, having a focus on sustainable mobility and resource efficiency. By making use of highly reliable and integrated wide-bandgap (WBG) technologies in electronic power circuits and systems of electrified vehicles, testing systems, and charging infrastructures, HiEFFICIENT will directly support the development towards a more resource-efficient and decarbonized transportation system. Within HiEFFICIENT the partners will work towards next generation of WBG semiconductors in the area of smart mobility.
The goals of this projects are:
- Reduction in volume of 40%, by means of integration on all levels (component-, subsystem- and system level),
- Increase efficiency beyond 98%, while reducing losses of up to 50%,
- Increase reliability of WBG power electronic system to ensure a lifetime improvement of up to 20%.
HiEFFICIENT is driven by 10 industrial use cases (UCs). They include, amongst others, modular inverters with different voltage levels (such as 48V and 400V), flexible on- and multi-use off-board chargers for different voltage levels, multi-purpose DC/DC converters and test systems for power electronics’ lifetime testing.
In HiEFFICIENT, the ISEA focuses on optimizing the design of power modules and the selection and positioning of module-integrated thermal sensors. The goal here is to improve the sensor performance as well as the thermal performance of the power module. Furthermore, the ISEA investigates thermal condition monitoring systems as well as active thermal management methods for drive inverters to enable aging diagnostics, predictive maintenance and to increase active lifetime and power density.
