Power and sensor technology company onsemi (formerly ON Semiconductor) has announced that NIO selected its VE-Trac Direct SiC power modules for its next-generation EVs.
The SiC VE-Trac Direct is a 900 V power module with integrated single-side direct cooling that incorporates onsemi’s second-generation SiC MOSFET technology. onsemi says “An integrated pin fin baseplate enables direct liquid cooling and easy assembly, which allows maximum power output and more efficient thermal dissipation.”
“From all the solutions we considered, the VE-Trac Direct SiC traction power modules offered the best efficiency during testing, allowing us to extend our NEDC range by 4% compared to the current silicon solution,” said Senior VP at NIO Alan S. Zeng.
The power modules have a six-pack configuration and a low turn-on resistance of 1.7 mohm.
“onsemi is the only supplier of silicon carbide solutions with vertical integration capability including SiC boule growth, substrate, epitaxy, device fabrication, best-in-class integrated modules and discrete package solutions,” said Executive VP and GM of the Power Solutions Group at onsemi Simon Keeton.
