High efficiency, high power density, cost effective, scalable and modular power electronics and control solutions for electric vehicles

Project description

The future of battery electric vehicle architectures

Battery electric vehicles (BEVs) are powered entirely by electricity. Since BEVs are not designed like gas-powered vehicles, there is no reason the architecture should be the same. The EU-funded HighScape project will explore the feasibility of a family of highly efficient power electronics components and systems, including integrated traction inverters, onboard chargers, DC/DC converters, and electric drives for auxiliaries and actuators. To pave the way for zero tailpipe emission road mobility, the project will test its proposed solutions on two differently sized BEV prototypes. For instance, the project will introduce new solutions for the auxiliaries and chassis actuators, as well as higher levels of power density, specific power and energy efficiency.

Objective

Focused on BEV architectures with distributed multiple wheel drives, and, specifically, in-wheel powertrains, HighScape will explore the feasibility of a family of highly efficient power electronics components and systems, and including integrated traction inverters, on-board chargers, DC/DC converters, and electric drives for auxiliaries and actuators. The proposed solutions will be assessed on test rigs and on two differently sized BEV prototypes. The project will result in: i) component integration with the incorporation of the WBG traction inverters within the in-wheel machines to achieve zero footprint of the electric powertrain on the sprung mass; the functional integration of the traction inverter with the on-board charger, and the incorporation of the latter and the DC/DC converters within the battery pack; and the implementation of multi-motor and fault-tolerant inverter solutions for the auxiliaries and chassis actuators; ii) novel solutions, including the implementation of reconfigurable winding topologies of the drive, as well as integrated and predictive thermal management at the vehicle level, with the adoption of phase changing materials within the power electronics components; iii) the achievement and demonstration of significantly higher levels of power density, specific power and energy efficiency for the resulting power electronics systems and related drives; iv) major cost reductions thanks to the dual use of parts, subsystem modularity, and model-based design to eliminate overengineering; and v) increased dependability and reliability of the power electronics systems, enabled by design and intelligent predictive health monitoring algorithms.
Through HighScape, the participants will establish new knowledge and industrial leadership in key digital technologies, and, therefore, directly contribute to Europe’s Key Strategic Orientations as well as actively support the transformation towards zero tailpipe emission road mobility (2Zero).
