BYD is reportedly developing its second-generation megawatt flash charging system, with leaked details revealing impressive capabilities that push EV charging technology further.

  According to unofficial sources, including technical nameplate information and reports from Chinese online forums and a tech blogger on Weibo, the upgraded charger could deliver up to 1,500 kW (1.5 MW) of power and handle a maximum current of 1,500 A. This marks a substantial 1.5x improvement over BYD's first-generation megawatt system, introduced in 2025, which achieved 1,000 kW power and 1,000 A current.

   The leaked specifications highlight a wide voltage range of 500–1,000 V, support for charging rates exceeding 10C, and peak power potentially reaching around 1,360 kW in operation. With these advancements, the system is estimated to add approximately 400 km (about 250 miles) of driving range in just five minutes—maintaining the ultra-fast performance benchmark set by the previous generation while increasing overall capacity.

   The design incorporates a compact T-shaped dual-gun configuration with a small footprint of roughly 1.5 m². It uses lightweight liquid-cooled cables weighing about 2 kg each, along with intelligent power distribution to optimize efficiency and reduce strain on the electrical grid and transformers. A key upgrade is the doubled energy storage capacity at each station compared to the first generation, allowing more than 20 consecutive vehicle charges without significant grid dependency.

   The system is said to be compatible with BYD's flagship models, such as the Han and Tang series, along with other high-voltage electric vehicles equipped for fast-charging battery packs and drivetrain architectures.

   For context, BYD's original megawatt flash charging—launched in March 2025 as part of the Super e-Platform—already set industry records for mass-produced passenger EVs, enabling 1 MW charging and rapid range addition. The company has aggressively expanded deployment, with over 500 megawatt-class stations operating across more than 200 Chinese cities by late 2025, and ambitious plans (in partnership with entities like Xiaoju Charging and Xindiantu) to reach over 15,000 stations in 2026. Existing first-gen stations can also be upgraded to support 500 kW ultra-fast charging via modifications.

   This development arrives amid fierce competition in China's EV market for ultra-fast charging. Rivals include:

• Zeekr at around 1.2 MW

• Xpeng at approximately 800 kW

• Nio at about 640 kW

• Li Auto at around 520 kW

• Tesla V4 Superchargers at up to 500 kW

   Huawei and Didi have also announced megawatt-class solutions. BYD's push toward even higher power levels reflects the ongoing race to minimize charging times and alleviate range anxiety, supported by high-voltage platforms and advanced battery tech.

   Note that these details stem from leaks and unofficial reports—no official confirmation from BYD has been issued regarding the 1,500 kW system, including exact vehicle compatibility, battery requirements, or rollout timelines. The information should be treated as preliminary until verified by the company.
