Leaked nameplate information and recent Chinese online reports indicate that BYD’s second-generation megawatt flash charging system could support up to 1,500 kW and 1,500 A. This represents a 1.5-times increase over the first-generation system introduced in 2025.
Technical specifications cited in forums and news posts indicate a maximum DC voltage of 1,000 V and an input capacity of 2,100 kW to support grid management. The parameters suggest a potential reduction in charging time for high-voltage electric vehicles and higher support for fast-charging battery packs and drivetrain architectures.
According to a Chinese tech blogger, the second-generation stations have been partially revealed online. These unofficial reports indicate a peak power of up to 1,360 kW, supporting 10C+ charging, with an estimated five-minute range gain of approximately 400 km. The stations are reportedly compatible with BYD Han, Tang, and other flagship models.
The blog also describes a T-shaped dual-gun design with a 1.5 m² footprint, 2 kg liquid-cooled cables, and intelligent power distribution. Single-station energy storage has reportedly doubled compared with the first generation, enabling more than 20 vehicles to charge consecutively.
BYD introduced its first-generation megawatt flash charging system at a product launch on March 17, 2025. That system was integrated with a high-voltage electric platform and was disclosed to support a charging current of 1,000 amperes, a peak charging power of 1,000 kilowatts, and a battery pack charging capability of up to 10C. The first-generation system could add approximately 400 kilometers of driving range in five minutes under test conditions.
The unofficial reports indicate that second-generation stations support a 500–1000 V wide-voltage platform. Existing first-generation stations can reportedly be upgraded to 500 kW ultra-fast charging via dual-gun and intelligent-boost modifications. A “youth version” of stations with 200–600 kW of power is also said to be in development to accommodate a wider range of vehicles.
As of late 2025, BYD had deployed over 500 megawatt-class charging stations across more than 200 cities in China. The company plans to expand the network further in 2026. A three-tier network layout comprising flagship, satellite, and community stations is reportedly planned. Partnerships with Xiaoju Charging and Xindiantu aim to support the construction of more than 15,000 stations by 2026.
The leaked nameplate and forum reports suggest that the second-generation system increases electrical limits relative to the first generation. The charger is reportedly designed with IP55 protection and measures to mitigate impacts on the transformer and the grid. An official BYD confirmation has not been issued, and vehicle model applications, battery chemistry updates, and deployment timelines for the 1,500 kW system remain unverified.
Ultra-high-power charging is increasingly competitive in China’s electric vehicle market. Tesla’s V4 fast-charging system reaches about 500 kilowatts, Li Auto’s system around 520 kilowatts, Nio’s system approximately 640 kilowatts, and Xpeng’s system around 800 kilowatts.
Zeekr has disclosed a 1.2-megawatt charging station, while Huawei and Didi have announced megawatt-class charging solutions. These developments reflect a broader industry push toward ultra-fast charging and high-voltage electric platforms.
Chinese manufacturers continue to expand charging infrastructure alongside vehicle development. BYD’s 1000 kW megawatt flash chargers have been integrated into the company’s Super e‑Platform vehicles. Deployment is being scaled nationwide, and international expansion is underway. Other automakers, including Li Auto, Xpeng, and Zeekr, are also increasing ultra-fast charging station construction across China.
The leaked specifications define BYD’s second-generation megawatt flash charging system with a maximum current of 1,500 amperes and a maximum power of 1,500 kilowatts. The technical details reported on social media and blogs are unofficial and unconfirmed.
