When Xiaomi throws its hat into the electric vehicle ring with the new SU7, it’s going to pack a serious silicon carbide punch thanks to a supply deal with semiconductor giant Infineon.
Under the agreement announced, Infineon’s HybridPACK Drive CoolSiC modules and bare dies will be integrated into Xiaomi SU7 powertrain for extra oomph. Silicon carbide (SiC) power modules wizardry allows higher operating temperatures for best-in-class performance, range, and driving dynamics that’ll put plenty of pep in the SU7’s step.
Following our previous coverage of Xiaomi’s plans to release track package for SU7, this aligns with earlier reports detailing Xiaomi’s development of the V8s high-speed motor, dubbed the “Super Motor.” Xiaomi has confirmed that vehicles equipped with this amped-up drivetrain will begin production by the end of 2024.
But the silicon carbide saga doesn’t stop there. Infineon is also hooking Xiaomi up with a full buffet of other automotive goodies, including EiceDRIVER gate driver ICs and over 10 different microcontroller variants for various onboard systems. Two companies will collaborate further on squeezing every last drop of performance from Infineon’s expansive SiC portfolio.
“Infineon’s leading technologies and manufacturing muscle for power semiconductors, combined with their broad microcontroller lineup, made them an ideal partner,” said Zhenyu Huang, Xiaomi EV’s supply chain chief. “This cooperation stabilizes our silicon carbide supply while enabling a high-performance, safe, and reliable luxury EV packed with leading-edge features.”
For Infineon’s automotive boss Peter Schiefer, the Xiaomi deal represents a prime opportunity to work with an upstart EV disruptor while showcasing the semiconductor firm’s automotive prowess. “We’re well-positioned with our extensive product range, systems know-how, and multi-site manufacturing to help shape the mobility future,” said Schiefer.
