World’s best-selling EV brand looks to push its self-developed fast charging technology to new heights.
Leaked nameplate information suggests BYD’s second-generation megawatt charging system could deliver up to 1,500 kW of power and 1,500 A of current, representing a 1.5-times increase over the company’s first-generation system introduced in 2025.
The unofficial specifications, cited in Chinese forums and social media posts, indicate a maximum DC voltage of 1,000 V and an input capacity of 2,100 kW to support grid management.
These parameters suggest potential charging time reductions for high-voltage electric vehicles (EVs) and enhanced support for fast-charging battery architectures.
The first-generation stations, launched last year, feature peak charging power of up to 1,000 kW, supporting 10C charging on BYD’s Han L and Tang L electric models, and charging of 400km in just five minutes if two guns are used together.
Enhanced design and capabilities
The leaked information describes a T-shaped dual-gun design with a 1.5 square metre footprint, 2kg liquid-cooled cables, and intelligent power distribution systems. Single-station energy storage has reportedly doubled compared with the first generation, enabling more than 20 vehicles to charge consecutively.
BYD’s first-generation megawatt flash charging system, launched on 17 March 2025, supported charging current of 1000 amperes and peak charging power of 1000 kilowatts. That system could add approximately 400km of driving range in five minutes under test conditions.
The unofficial reports indicate 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 through dual-gun and intelligent-boost modifications, while a “youth version” of stations with 200–600 kW of power is also said to be in development.
Rapid infrastructure expansion
As of late 2025, BYD had deployed over 500 megawatt-class charging stations across more than 200 cities in China, with plans to expand the network further in 2026 through a three-tier layout comprising flagship, satellite, and community stations.
Partnerships with Xiaoju Charging and Xindiantu aim to support construction of more than 15,000 stations by 2026.
The leaked specifications suggest the second-generation system includes IP55 protection and measures to mitigate impacts on transformers and the grid.
Competitive charging landscape
Ultra-high-power charging has become increasingly competitive in China’s EV market. Tesla’s V4 fast-charging system reaches approximately 500 kilowatts, while Li Auto’s 5C system delivers around 520 kilowatts. NIO’s system provides approximately 640 kilowatts, and XPeng’s system reaches 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.
The leaked specifications remain unofficial and unconfirmed by BYD. Vehicle model applications, battery chemistry updates, and deployment timelines for the 1,500 kW system have not been verified, however, the reports highlight the continued advancement of charging infrastructure alongside China’s rapid EV development.
