Wolfspeed has signed a multiyear supply agreement to provide BorgWarner with silicon carbide devices for electric vehicle inverters. This partnership helps secure the hardware needed for high-voltage 800V inverter platforms using advanced 1200V technology.
Why it matters
Automakers are increasingly prioritizing high power density to improve vehicle efficiency and charging speeds as electric vehicles become more common. This supply chain development supports the manufacturing capacity required to scale these power electronics for the next generation of EVs.
The agreement centers on 1200V silicon carbide technology engineered for 800V inverters, produced using 200mm wafers. These components represent a significant portion of the hardware needed to meet the growth in global EV market share from 25% in 2025 toward 50% by 2035.
The players
Wolfspeed
A semiconductor manufacturer specializing in silicon carbide materials and power devices for the automotive and energy sectors.
BorgWarner
A global automotive supplier known for developing propulsion systems and inverter technology for electric and hybrid vehicles.
The details
Silicon carbide devices are essential for electric vehicles because they handle high heat and voltage more efficiently than traditional silicon. Wolfspeed produces these semiconductors on 200mm wafers at its United States facilities, providing the high power density necessary for BorgWarner to manufacture its advanced inverter platforms. These inverters act as the brain of the electric drivetrain, converting battery power to drive the motor, which allows for faster charging and improved range.
Timeline
2025 marked the period when electric vehicles reached 25% of global new car sales.
2035 is the year the International Energy Agency projects electric vehicles will reach 50% of global sales.
The Home Front
This supply agreement reflects a broader shift toward 800V architectures in the automotive market to reduce charging times for household vehicles. It highlights how manufacturers are securing long-term semiconductor production to manage the scaling demand of the electric vehicle transition.
As high-voltage charging becomes more common, prioritize checking if your household electrical capacity can support home charging solutions for next-generation electric vehicles. Consult a licensed electrician to evaluate your home's infrastructure before installing high-speed, 800V-compatible wall chargers.
The takeaway
This partnership ensures that the high-performance semiconductor components required for faster EV charging remain in consistent supply. Watch for more vehicles featuring 800V charging capabilities as these specialized power electronics reach the consumer market in the coming years.
