Li Auto introduced right now that on the “China Coronary heart” 2026 Powertrain Day and the tenth China Automotive Powertrain Know-how Convention, the Li Auto i8, geared up with the corporate’s in-house high-voltage silicon carbide (SiC) electrical drive system, was awarded the title of “High 10 New Vitality Automobile Powertrain Methods of the Yr.”
The system stood out with an industry-leading electrical drive effectivity of 93.08%, together with a number of proprietary applied sciences, together with Li Auto’s self-developed SiC energy chips.
Because the core expertise platform of the Li Auto i8, the high-voltage SiC electrical drive system achieves full-stack in-house improvement, protecting energy chips, energy modules, motor controllers, electrical motors, discount gearboxes, and management software program. This permits the automobile to succeed in a CLTC-rated vary of 720 km, with vitality consumption as little as 14.8 kWh per 100 km.
With a peak effectivity of 93.08%, the system units a brand new {industry} benchmark. For customers, this interprets into longer driving vary and decrease vitality loss per kilowatt-hour.
In response to Li Auto, a key enabler is its industry-first SiC chip that includes a hexagonal cell construction, designed for high-voltage, high-current situations. In contrast with typical designs on the identical energy degree, the chip delivers decrease inner resistance, quicker warmth dissipation, and extra uniform thermal distribution.
As well as, Li Auto’s self-developed motor lubricant considerably reduces losses in chilly environments, enhancing driving vary by 10–16 km at –7°C. Paired with a 97.8 kWh 5C ultra-fast charging battery, the system helps 500 km of vary from simply 10 minutes of charging, balancing long-range functionality with fast vitality replenishment.
