Chinese automaker BYD has announced a game-changing product for EV charging.
The company unveiled a new battery system called Blade Battery 2.0, which it says can charge from 10% to 70% in roughly five minutes. Pushing it close to full capacity takes about four minutes more. If those figures translate outside lab conditions, the familiar complaint about EV charging time starts to lose its weight.
The battery will first appear in the Yangwang U7, a luxury sedan from BYD’s high-end brand. In cold conditions as low as –20°C, the company says the pack can still jump from 20% to 97% in under 12 minutes. For drivers used to waiting far longer at charging stations, that kind of speed changes the rhythm of owning an EV.
There is, however, an important catch. Those charging times rely on a new infrastructure system BYD calls Flash Charging, capable of delivering up to 1.5 megawatts of power. That level of output sits far above the chargers most drivers encounter today. In many parts of the US and Europe, fast chargers top out around 350 kilowatts, though some 500 kW systems are starting to appear.
Still, the strategy fits into a broader shift already happening across the EV industry. BYD built the Blade Battery 2.0 using lithium iron phosphate (LFP) chemistry, a type of battery that avoids expensive materials such as cobalt and nickel. According to BloombergNEF estimates, LFP packs cost about $81 per kilowatt-hour, compared with roughly $128 per kilowatt-hour for nickel-manganese-cobalt batteries.
Lower cost explains why many manufacturers rely on LFP for entry-level vehicles. The trade-off has always been lower energy density, which means shorter driving range. BYD’s approach focuses on attacking the problem from another angle. Faster charging reduces the pressure to squeeze every possible kilometre from a battery.
The Yangwang U7 is rated at just over 1,000 kilometres on China’s CLTC test cycle, though that testing method tends to be generous. In real-world terms, the range may land closer to about 400 miles. That trails vehicles like the Lucid Air Grand Touring, which carries an EPA-rated range of 512 miles.
BYD also appears to be thinking beyond the vehicle itself. The company says it already has more than 4,200 Flash Charging stations installed across China and plans to add about 16,000 more by the end of the year. Some locations will include grid-scale battery storage to manage the enormous power draw required for megawatt charging.
This infrastructure push comes at a time when BYD has grown into the world’s largest EV manufacturer, competing with companies such as Tesla while facing intensifying competition from domestic rivals including Li Auto and XPeng.
But sales momentum has softened slightly this year, with early 2026 figures dipping compared with the previous year. Technologies that shorten charging time could help the company regain momentum in a market where new models arrive almost monthly.
Whether Blade Battery 2.0 reshapes the EV landscape depends on one factor beyond the battery itself. Charging stations capable of delivering megawatt-level power need to spread quickly enough to make the promise practical.
