High-voltage Fast-charging Efficient Electric Vehicle Powertrains

The HiVEP project is a groundbreaking initiative set to revolutionize electric vehicle (EV) efficiency and performance through advanced high-voltage powertrain technologies. Targeting mass-market C-segment vehicles, HiVEP introduces powertrain architectures operating above 800V, enhancing vehicle performance by integrating ultra-efficient power electronics with advanced SiC semiconductors, Active Winding Reconfiguration, integrated chargers, and rare-earth-free electric machines optimized for high voltages. It also includes high-energy-density batteries with 3.6 C-rate and optimized thermal management. These innovations aim to drastically reduce EV charging times at under 10 minutes —a significant adoption barrier—reducing energy consumption by 25%, boosting range by 20% and enhancing driving dynamics. HiVEP also emphasizes the safety and sustainability of its systems, promoting resource efficiency and a lower lifecycle footprint through reduced material usage and energy consumption. Finally, it strives to maximise the affordability and cost competitivess of the innovations, by reducing future powertrain costs by 10-20% at mass production levels.
