BYD tests 1,500 kW flash charging system, nearly three times Tesla V4 power capacity
China – BYD is conducting internal testing of a megawatt-class fast-charging network in Shenzhen, China, following earlier leaks regarding a 1,500 kW charging system and dedicated Flash Charging application.
Attendees at the demonstration site shared images of a testing station near BYD’s headquarters, equipped with next-generation high-power cabinets. The site layout resembles an electric vehicle charging station with liquid-cooled charging guns and a T-shaped canopy structure. Previous leaks published by local media revealed specification plates indicating peak power output of up to 1,500 kW and current capacity of 1,500 amperes, built on a 1,000 volt electrical architecture.
In the latest testing session, access appeared restricted to vehicles bearing the “Flash Charge” badge on the rear, including the BYD Tang 9, Song Ultra, Seal 07, Denza Z9 GT, and upcoming FCB Tai series models.
Screenshots circulating from early users show the Flash Charging application is already available on Android. The interface allows users to search for nearby stations and supports automatic plug-and-charge activation. Once activated, charging reportedly begins within approximately 10 seconds of cable connection without requiring QR code scanning. Integration with Sesame Credit is also visible in previous leaked screenshots.
The price displayed at the demonstration site is 1.3 yuan (approximately £0.15) per kilowatt-hour, comprising 1 yuan (approximately £0.12) for electricity and 0.3 yuan (approximately £0.04) as a service charge. Purchasers of flash-charge-compatible vehicles are reported to be entitled to 1,000 kilowatt-hours of free electricity annually, although formal policy documents have not yet been published.
The 1,360–1,500 kW hardware capacity mentioned in the leaks represents approximately three times Tesla’s current peak power of 500 kW and more than double the typical upper limit of 600 kW for public chargers.
Earlier reports indicated that BYD is targeting over 4,000 self-operated flash charging stations nationally, with a broader partnership network potentially exceeding 15,000 locations including partners such as XiaoJu Charging. However, an official national rollout schedule has not yet been announced.
The current phase remains internal testing. Verified operational data, including sustained peak power curves, five-minute range recovery data, and a large-scale rollout timeline, are expected to be announced at an upcoming launch event.
