BYD Blade Battery 2.0 charges to 97% in landmark nine mins

BYD Chairman Wang Chuanfu unveiled the company’s second-generation Blade Battery at an event on 5 March, promising a full charge from 10% to 97% in an average of nine minutes and an energy density improvement of more than 5% against its predecessor. The launch is the most significant battery from the automaker since the original Blade Battery debuted in 2020, and comes as it reckons with a sharp sales backslide. 

Ten models have been selected for the new technology to debut. Among them is the Yangwang U7, which is fitted with a 150 kWh pack and boasts a range of 1,006 km under CLTC conditions. Meanwhile, the Denza Z9GT reaches 1,036 km, marking the first time a quad-motor configuration has exceeded 1,000 km of range. BYD has also increased the guaranteed capacity retention rate by 2.5%.

Cold-weather performance is central to BYD’s pitch for the technology. After being held at minus 30 degrees Celsius for 24 hours, the battery charges from 20% to 97% in 12 minutes. only three minutes longer than at ambient temperature. Wang framed this as resolving one of the persistent challenges of EV ownership in China’s northern provinces.

Charging speeds are notably consistent across the full compatible model range. Across the ten vehicles tested, the 10%-to-70% charge falls between four minutes 54 seconds and five minutes 11 seconds; while the 10%-to-97% window runs from eight minutes 45 seconds to nine minutes 24 seconds. In other words, a spread of under 40 seconds at either threshold regardless of vehicle class or battery size. On standard public charging infrastructure, the new battery charges 30% to 50% faster than conventional EV batteries.

BYD is building a dedicated Flash Charging network to support the technology, targeting 20,000 stations by the end of 2026. Of this number, the vast majority—around 18,000—will be embedded within existing public charging sites. The automaker has stated it will be using on-site energy storage batteries to avoid additional strain on the power grid. Some 4,239 stations had already been completed as of 6 March, with 2,000 highway locations planned to ensure coverage at 100 km intervals.

The reveal arguably comes at a timely moment for BYD as it battles against backsliding domestic sales. BYD recorded its sixth consecutive month of falling sales in February 2026, with volumes down 41% year-on-year to 190,190 units due in part to the Chinese New Year. Combined with January—to offset the impact of the festival—the figure represents a 36% decline against the same two-month period in 2025. 

The battery launch echoes BYD’s response to its previous sales trough: in February 2025, the company unveiled its God’s Eye autonomous driving system and absorbed it into vehicle prices at no additional cost. The Blade Battery 2.0 serves a similar strategic function, providing a headline technology narrative at a moment when domestic demand is faltering and the Chinese government clamps down on years-long price wars.
