Report stating the current EV market demand for e-powertrain units. The report will consider technical needs as well as economic requirements and regulations boundary conditions. Associated to tasks 1.1, 4.1 and 4.2
A validation plan which includes a test matrix describing the test to be performed to assess the predefined requirements. Associated to task 1.3
The report will describe the performance of an innovative slot molding (a replacement for liners with improved thermal conductivity) and the final decision about the insulation system to be used in the HEFT machine. Associated to task 2.4
Definition of the modular, high-efficient and cost-oriented 800V powertrain architecture. Associated to task 3.1
Improved SiC-based high voltage drive control to reduce powertrain losses and improve EV range. Associated to task 3.2
Design of eMotor active part for class A+B vehicle. Design to minimize magnet volume and reducing iron losses, based on recycled NdFeB and /or NdCeFeB magnets. Report showing the design process of the rotor. The report should include study of the most convenient rotor topology using recycled NdFeB or NdCeFeB magnets with the use of high strength over moulded epoxy. In addition, it should include the resistance of the rotor to demagnetisation and the incorporation on the rotor of the appropriate cooling circuit. The report should include the optimisation process to reduce iron and magnet losses and improve efficiency over the WLTP driving cycle. Associated to task 4.1
A tentative plan describing the type and timing of dissemination activities. The plan will be updated based on contingencies or opportunities. Associated to task 7.2.
