Huawei officially released the SiC electric drive platform
On April 17, Huawei officially announced that during the same period of the Shanghai International Automobile Industry Exhibition (4/18-27), Huawei held a new smart electric product launch conference and released the "DriveONE new generation hyper-converged the charging network solution of "Golden Power Platform" and "New Generation Full Liquid-cooled Supercharge Architecture".
Equipped with SiC, Huawei creates a high-efficiency high-voltage electric drive platform
Among them, DriveONE's new-generation hyper-converged golden power platform mainly includes powertrain solutions for B/B+ class pure electric vehicles, B/B+ class extended-range hybrids, and A-class pure electric vehicles. and fuel mileage, to achieve higher mileage with the same battery power. It is worth noting that the platform is equipped with high-efficiency SiC silicon carbide technology, leading the industry in terms of performance, efficiency, charging speed and cruising range.
For B/B+ class BEV powertrain
According to Huawei, DriveONE's next-generation hyper-converged golden power platform is the industry's most efficient mass-produced high-voltage synchronous assembly solution. Based on high-efficiency SiC modules and Huawei's motor simulation and optimization platform, Huawei has created the industry's most efficient CLTC process with 92% CLTC efficiency. In terms of powertrain, compared with similar solutions in the industry, the efficiency is 1.5 percentage points ahead; this platform supports dual voltage adaptation of 750V and 900+V at the same time, and can realize extremely fast 4C charging on a 250A fast charging pile, and the battery can be charged in 7.5 minutes. The SOC is increased from 30% to 80%, and the battery life is increased by 250km.
In addition, this platform is also the highest density and best auxiliary drive asynchronous assembly in the industry. Thanks to a series of technological breakthroughs such as speed increase and intelligent oil cooling, the powertrain power density has reached 2.4kW/kg, leading the industry by 30%. The asynchronous assembly equipped with Huawei's intelligent auxiliary drive technology is equipped with a 92% efficient synchronous rear drive assembly. The overall four-wheel drive mileage can be increased by 27km, which is equivalent to the ultimate driving experience of "four-wheel drive performance and two-wheel drive battery life".
For B/B+ level REV powertrain
Huawei calls it the optimal solution for high-end hybrid four-wheel drive. For the range-extending four-wheel drive scenario, Huawei launched the industry's first asynchronous five-in-one, which has system efficiency optimization and a low drag torque design that is 26% better than the industry. It can reach 88.2%, leading the industry by 5+%, and the cruising range with full fuel and full charge has increased by 44km. At the same time, this solution achieves the optimal design in the Y direction, which can support the upgrade of the vehicle suspension and make the layout of the vehicle's double-wishbone suspension simpler. DriveHybrid High-end hybrid DRT assembly, four-wheel drive and two-wheel drive battery life.
For A-class BEV powertrain
Through the first chip integration, power integration, function integration and domain control integration, the super-integrated 10-in-1 power domain module can reduce the number of BOM by 40% and the number of chips by 60%. The power domain module allows car companies to realize the simple integration, verification and development of the power domain, and the development efficiency is increased by 30%. At the same time, the super-integrated power domain module is adopted, the layout of the front cabin of the vehicle is simpler, the front trunk can be set, and more space in the car can be released to improve the driving comfort of users and bring the space of a B-class car to the A-class pure electric car and experience.
