It targets takeover frequency less than once per 1000 km in highway scenarios in 2023 and takeover frequency less than once per 100 km in urban scenarios by 2025.
Xmart OS In-car Operating System: Xmart OS leverages a multi-sensor software and hardware platform to augment and transform control and driver-vehicle interaction. Powered by AI, supercomputers and foundation models, Xmart OS can make intelligent decisions to optimize control of cabin functions. The SEPA2.0-based R&D platform lowers Xmart OS software adaptation costs by 85%, shortens voice software R&D cycle by 50% and reduces cost of voice assistant service by 50%, making the industry’s top smart cabin services available to every XPENG owner, while revolutionizing cockpit instrumentation and road perception.
X-EEA Electrical and Electronic Architecture: Consisting of a data technology platform, a whole-car software platform and a hardware architecture platform, X-EEA underpins XPENG’s technology foundation with high performance, superior safety and cloud application integration. It optimizes overall vehicle R&D costs by 50%, shortens software iteration cycles by 30% and increases OTA update speed by 300%.

Architecture-based Solutions to Boost Charging Efficiency

800 Volt High Voltage Silicon Carbide (SiC) Platform: XPENG’s industry leading superfast charging solution enables 800V high voltage charging, increasing battery charging speed by 50% over the previous generation. With a standard 3C cell configuration, the battery can add 130 kilometers of range with a five-minute charge, and can charge even faster at XPENG’s S4 480kW superfast charging facilities, adding 200 km of range with a five-minute charge. When charging via third-party charging piles, it can generate up to 180kW of charging power.
XPower 800 Volt High Voltage Oil-cooled Flat-wire SiC Integrated Electric Drive System: Full-stack and in-house developed, XPower increases the maximum electric drive efficiency to 97.5% and the overall electric drive efficiency to 92%. Each 1% increase in overall electric drive system efficiency, with other conditions unchanged, translates into an estimated 2% increase in EV range. Powerful system integrations deliver industry-leading power-to-weight ratio of 2.5 kW/kg, ensuring less whole-car weight while creating a more spacious and quieter cabin.
X-HP Smart Thermal Management System: X-HP offers an intelligent, systematic energy-efficient solution for temperatures from -30℃ to 55℃, ensuring range and charging capacity under all weather conditions. In cold conditions, it increases range by 15%; it improves battery cooling performance by 100%, leading to a 90% increase in charging power.
Powerful Fast-Charging Network: Consisting of 7kW and 11kW home charging piles, 20kW DC fast-charging piles, S2 180kW DC supercharging piles and S4 480kW DC superfast charging piles across China, XPENG’s charging network continues to expand. In 2023, approximately 500 new S4-enabled XPENG superfast charging stations will become operational.

Advanced Manufacturing Capabilities

Front and Rear Integrated Aluminum Die Casting Technology: One of its kind in mass production models in China, enables more uniform fabrication of the car body, bringing more stable control and a better driving performance. It also improves torsional rigidity by 83% compared to a traditional car body, enhancing body safety, while at the same time reducing body weight by 17% versus traditional bodies, further boosting EV range.
CIB (Cell Integrated Body) Technology: Battery pack integrated in the car body optimizes cabin design with added vertical space, increases battery safety and enhances overall driving performance by improving center of gravity. With an 80-ton side collision resistance design and a IP68 waterproof & dustproof design, the CIB battery pack meets the highest safety standards in three main markets: China, North America and Europe.
Chassis Platform: Compatible with multiple types of suspension systems, providing superior mechanical quality and excellent handling performance.
Smart Manufacturing System: This system will be built out by 2025, including the Zhaoqing Plant, Guangzhou Base and several future projects. All manufacturing facilities will integrate SEPA2.0 through technology upgrades.
