Chinese electric vehicle giant BYD has unveiled a major breakthrough in electric vehicle battery technology that could dramatically reduce charging times. The company introduced its second-generation Blade battery along with new “flash charging” technology, claiming compatible electric vehicles can be charged from 10% to 70% in about five minutes and up to 97% in about nine minutes.
The announcement positions BYD as one of Tesla’s key competitors in the race to make electric vehicles as convenient as gasoline-powered cars.
A breakthrough in electric vehicle charging speed
The new battery system is part of BYD’s next generation Blade Battery 2.0, which improves energy density, charging speed and thermal management compared to the previous generation. The company says the improved battery can work efficiently in extreme conditions, charging from 20% to 97% in under 12 minutes, even in temperatures as low as -20°C.
Blade Battery 2.0 is based on lithium iron phosphate (LFP) chemistry but features a redesigned structure that increases energy density and durability while reducing production costs. The battery can support extremely high charging rates, enabling the ultra-fast “flash charging” capability that BYD demonstrated during the launch event.
The technology will be used for the first time in high-end vehicles such as the Yangwang U7, which is said to offer a range of more than 1,000 kilometers on a single charge according to CLTC testing standards.
Charging speed has long been one of the biggest barriers to wider EV adoption
While modern electric cars have significantly improved battery range, charging times often remain longer than when refueling a gasoline vehicle. BYD’s new battery and megawatt charging system aims to close this gap. The company’s “Flash Charging” network can deliver extremely high power, enabling ultra-fast charging. In some demonstrations, the technology can reach hundreds of kilometers in just a few minutes.
If the technology proves reliable on a large scale, it could significantly reduce range anxiety and significantly shorten electric vehicle charging stops.
For electric vehicle owners, faster charging could transform the driving experience
Instead of waiting 30 minutes or more for a typical quick charge, drivers may only need a few minutes to significantly increase their vehicle’s range. This improvement could make electric cars much more practical for long-distance travel and everyday use, especially in regions where charging infrastructure is still being developed.
Additionally, BYD’s Blade battery technology is designed to improve safety and longevity and address common concerns about battery performance degradation and overheating. BYD plans to support the new battery technology with a major expansion of its ultra-fast charging infrastructure. The company has announced plans to build around 20,000 fast charging stations across China by the end of 2026, with thousands of them already under construction.
As automakers around the world compete to accelerate electric vehicle adoption, breakthroughs in battery technology like this could play a crucial role. If BYD’s ultra-fast charging system becomes widely available, it could push the entire industry – including Tesla and other leading electric cars – to move more quickly to truly gas station-like charging speeds.
