BYD kicked off a megawatt charging war in 2025, then followed it up with even faster second-generation "Flash" charging.
The Yangwang U7 can go from 10-97% in 9 minutes on a Flash charger.
To prove its durability, company did 18,000 miles at nearly 150 mph over 9 days, with 350 Flash charging stops, followed by a battery health test.
BYD kicked off a new phase of the charging war when it introduced "Megawatt Flash Charging" in 2025, offering speeds that could get your car from 10-60% in just 5 minutes. Competitors quickly responded, offering their own 1,000-plus-kilowatt solutions. Never one to sit still, BYD responded with a next-generation battery and charging system for its BYD, Denza, Yangwang, and Fangchengbao brands. Cars equipped with the new tech can charge from 10-97% in as little as 9 minutes, which is stunning performance.
But one question has lingered: How do these ultra-quick charging speeds affect battery longevity?
