Huawei’s powertrain shipments hit 1 million units in 2025 alone, as the company’s joint range-extender system with Xpeng showcases major breakthroughs in efficiency, NVH, and long-range performance.
Xpeng held a technical briefing for the Xpeng X9 in Songshan Lake, highlighting the jointly developed X9 Super Range-Extender Power System built with Huawei.
According to Wang Chao, President of Huawei Digital Power’s Intelligent Electric Product Line, Huawei’s cumulative powertrain shipments reached 1 million units by the end of 2024. In 2025 alone, shipments hit another 1 million units — exceeding the total of all previous years combined. About half of the shipped components are range-extender products.
Xpeng and Huawei formed their partnership in November 2024. Five Xpeng models will use Huawei’s powertrain systems in 2025, with more vehicles planned for 2026.
Wang outlined four major challenges tackled during the development of the Xpeng X9’s range-extender system:
Space Packaging Constraints: By designing a highly integrated generator and motor controller, the generator’s Y-axis dimension was compressed to ≤230 mm. Combined with Xpeng’s front-cabin integrated die-casting, the team achieved 82 component integrations and extended the available X-axis space by 23 mm — significantly improving front-cabin space utilization.
Achieving 1,602 km of Total Range: With an integrated high-voltage oil-cooled generator delivering ≥92% working-condition efficiency and 3.6 kWh/L fuel-to-electric conversion efficiency, plus Xpeng’s in-house high-voltage EV architecture, the system enables a 1,602-km combined range with best-in-class fuel consumption in low-battery scenarios.
Maintaining Battery Reserve and Consistent Power Delivery: The high-voltage oil-cooled generator provides a continuous 75 kW of power. Paired with Xpeng’s 800V coaxial silicon-carbide electric drive system with 93.5% comprehensive efficiency, the vehicle can cruise at 150 km/h without depleting the battery, and delivers best-in-segment low-SOC performance with no power drop even at 8% SOC.
Vehicle NVH Optimization: Xpeng’s self-developed cylinder-deactivation integration technology, combined with Huawei’s GCU control-strategy tuning, underwent over 10 rounds of joint calibration in three months, reducing range-extender startup vibration by 60%. Structural optimization of the “ultra-quiet” generator plus ENC active noise cancellation reduced generator engagement noise to just ≤0.5 dB.
