Descrizione del progetto
Il futuro delle architetture dei veicoli elettrici a batteria
I veicoli elettrici a batteria sono alimentati interamente da energia elettrica. Poiché non sono progettati come i veicoli a gas, non c’è motivo per cui l’architettura debba essere la stessa. Il progetto HighScape, finanziato dall’UE, esplorerà la fattibilità di una famiglia di componenti e sistemi elettronici di potenza altamente efficienti, tra cui inverter di trazione integrati, caricabatterie di bordo, convertitori DC/DC e azionamenti elettrici per ausiliari e attuatori. Per preparare il terreno alla mobilità stradale a zero emissioni di gas di scarico, il progetto testerà le soluzioni proposte su due prototipi di veicoli elettrici a batteria di dimensioni diverse. Ad esempio, il progetto introdurrà nuove soluzioni per gli ausiliari e gli attuatori del telaio, nonché livelli più elevati di densità di potenza, potenza specifica ed efficienza energetica.
Obiettivo
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).
