onsemi has secured a multi-year agreement with Volkswagen Group, positioning itself as the primary supplier of a comprehensive power box solution for Volkswagen’s next-generation electric vehicles (EVs). This collaboration highlights the synergy between technology innovators and automotive leaders in accelerating the global shift to sustainable transportation.
onsemi’s silicon carbide-based technologies lie at the heart of this partnership, integrated into a modular power box solution designed to elevate the efficiency and performance of Volkswagen’s Scalable Systems Platform (SSP). Scalable across all power levels, the system adapts seamlessly to several vehicle categories, ranging from high-power to low-power traction inverters.
Hassane El-Khoury, president and CEO of onsemi, stated, “By offering a complete power system solution that encompasses the entire power sub-assembly, we provide Volkswagen Group with a single, simplified modular and scalable platform that maximizes efficiency and performance for their vehicle lineup. This new approach allows for the customization of power needs and the addition of features for different vehicles without compromising on performance, all while reducing cost.”
The power box solution leverages onsemi’s EliteSiC M3e MOSFETs, delivering higher power capacity within a smaller footprint and significantly reducing energy losses. Three integrated half-bridge modules mounted on a cooling channel ensure effective heat management, enhancing performance, heat control, and efficiency. This advancement enables EVs to achieve greater range on a single charge, a critical factor for widespread adoption.
Volkswagen Group’s smooth transition to future EliteSiC-based platforms showcases the forward-thinking nature of this collaboration. Dirk Große-Loheide, Member of the Extended Executive Committee Group Procurement and Member of the Board Volkswagen Brand for Procurement, remarked, “We are very pleased to have onsemi as a strategic supplier for the power box of the traction inverter for our first tranche in the SSP platform. onsemi has convinced us with a deeply verticalized supply chain from the growth of the raw material up to the assembly of the power box.”
Till von Bothmer, Senior Vice President VW Group Procurement for Powertrain, underscored the advantages, “On top of the verticalization, onsemi has furthermore provided a resilient supply concept with regional silicon carbide fabs across Asia, Europe, and the U.S. In addition, onsemi will continuously provide the latest SiC generation to ensure competitiveness.”
onsemi plans to enhance its silicon carbide manufacturing capabilities in the Czech Republic, establishing an end-to-end production facility for the traction inverter power system. This investment strengthens Volkswagen Group’s supply chain resilience, improves logistics, and accelerates integration into the manufacturing process.
