BYD has been publishing fast charging figures for months without many independent verifications. Out of Spec Reviews' Kyle set out to change that, flying to Beijing specifically to test the flash charging system outside of any controlled media setting. The test subject turned out to be a Denza Z9 GT with its front bumper removed, sitting at 30 percent state of charge in the back of a dealership parking lot. No battery preconditioning, no climate control running, no prepared media vehicle. Kyle plugged it in cold, and the car climbed from 30 to 80 percent in five minutes. It reached 97 percent in just under eight minutes. The on-site charging hardware is BYD's own design, using a power cabinet drawing around 500 kilowatts from the grid and supplementing that with two on-site battery packs of 200 kilowatt-hours each, running at 1,000 volts.
The hardware story is bigger than one fast car. BYD's plan is to put the same Gen 2 blade cell into every vehicle it makes, from the cheapest entry models up to the high-end Yangwong brand. If that rollout lands as described, any BYD buyer would get the same charging window: 10 to 70 percent in around five minutes, 10 to full in around nine. The Denza Z9 currently on sale in Europe is the first vehicle in that market capable of accepting this level of charge. The charging station itself, a single cabinet with two dispensers, outputs up to two megawatts total and can serve two vehicles at peak speed simultaneously. Diego, who is overseeing the European flash charging network buildout, confirmed that in Europe the system will accept any CCS2 vehicle, though naturally only the fastest-capable cars get the full benefit.
The deployment numbers are large. At the time of filming, BYD had around 2,500 flash charge dispensers operational in China and planned to reach 20,000 by the end of 2026. For Europe, the target is 3,000 units in the near term, prioritizing retrofits of existing charging sites to move faster on permitting. Dealerships are the first wave, both for customer exposure and because staff can use the system's vehicle-to-grid capability to discharge the car at 200 kilowatts back into the station's battery storage, cycling demos repeatedly without grid strain. The cable itself is ceiling-hung, which removes almost all the weight from the handle and makes the plug-in experience noticeably easier than most CCS hardware in service today. No thermal throttling was observed during the test session, and the cable temperature was described as barely above ambient even at close to 900 kilowatts of throughput.
Bottom line: A crashed car, a dark parking lot, and an unscheduled test session. The numbers held up. The deployment scale is the next question, and that one will take a few years to answer properly.
