XPENG(US:XPEV) Guan Cha Zhe Wang·2025-12-05 13:35Core Viewpoint - The collaboration between Xiaopeng Motors and Huawei marks a significant advancement in the domestic smart electric vehicle industry, exemplified by the launch of the Xiaopeng X9 extended-range version featuring Huawei's DriveONE integrated high-voltage oil-cooled generator [1][12]. Group 1: Product Launch and Specifications - The Xiaopeng X9 extended-range version was officially launched on November 20, and it is the first extended-range product from Xiaopeng Motors [3]. - The vehicle features a "large battery + large fuel tank" design, equipped with a 63.3 kWh lithium iron phosphate battery and a 1.5T range extender, achieving a pure electric range of 452 km and a comprehensive range of 1602 km under CLTC conditions [3][11]. Group 2: Technical Challenges and Solutions - Traditional range extender systems were found inadequate for the performance requirements of the next-generation large seven-seater, leading to a collaboration between Xiaopeng and Huawei to develop the DriveONE generator, which addresses issues such as energy efficiency, electric range, and noise, vibration, and harshness (NVH) performance [5][11]. - The DriveONE generator boasts the highest power density in the industry, achieving a continuous power density of 1.88 kW/kg, and can provide a maximum power output of 85 kW when paired with the 1.5T range extender [7][11]. Group 3: Innovations in Noise and Vibration Control - The collaboration has led to the development of "precise active cylinder stop technology," which reduces noise and vibration by over 60% during engine start-stop events [9]. - Additional software features, such as "de-rotation control strategy," ensure stable and smooth operation across various driving conditions, enhancing the extended-range experience to closely resemble that of pure electric vehicles [9][11]. Group 4: Industry Implications - The successful launch of the Xiaopeng X9 extended-range version and the innovative partnership with Huawei provide a new model for collaboration in the domestic smart electric vehicle sector, showcasing advancements in electric drive systems, generators, and other components [12].
