BYD has officially revealed the next generation of its Blade Battery technology, introducing dramatically faster charging speeds and improved energy density.
The new battery, unveiled on Thursday alongside BYD’s “Flash Charging 2.0” system, is designed to support ultra-high charging power of up to 1,500kW, enabling EVs to replenish significant range in just minutes.
According to the company, vehicles equipped with the updated battery can charge from 10% to 70% in about five minutes, and from 20% to 97% in under 12 minutes, even in extremely cold temperatures as low as -20°C (-4°F).
These figures represent one of the fastest EV charging capabilities announced to date, potentially narrowing one of the remaining gaps between electric vehicles and traditional gasoline cars.
Faster charging and longer range
The second-generation Blade Battery continues to use lithium iron phosphate (LFP) chemistry, a technology BYD has championed for its safety, durability, and lower costs compared to nickel-based batteries.
BYD says the new cells offer about 5% higher energy density compared to the original Blade Battery introduced in 2020. While that increase may appear modest on paper, it translates into a noticeable improvement in driving range when applied across an entire battery pack.
For example, BYD says the Yangwang U7, equipped with a 150 kWh battery pack, can deliver up to 1,006 km (621 miles) of range on China’s CLTC testing cycle. Meanwhile, the Denza Z9GT is rated for up to 1,036 km (644 miles) under the same standard. Because CLTC estimates tend to be more optimistic, those figures would likely translate to roughly 450 miles (724 km) under the EPA test cycle.
The company also says the battery maintains improved durability, increasing the guaranteed capacity retention rate by 2.5% compared to the previous generation. BYD is also backing the technology with a lifetime warranty on the battery cells, signaling confidence in long-term reliability.
Designed for ultra-fast “Flash Charging”
To support these extreme charging speeds, BYD introduced its 1,500kW Flash Chargers, which are capable of delivering megawatt-class power to compatible vehicles.
The chargers feature a distinctive T-shaped design with overhead cables, allowing them to reach multiple charging ports more easily while managing the heavy cooling equipment required for such high power levels. In some cases, two cables can be connected to the same vehicle simultaneously.
BYD has also integrated on-site energy storage systems into the charging stations. These buffer batteries store electricity when vehicles are not charging and then release it during charging sessions, allowing the station to deliver extremely high power without overwhelming the local electrical grid.
Massive charging network planned
The automaker is planning a massive expansion of its charging infrastructure to support the new technology.
BYD says it intends to deploy 20,000 Flash Charging stations by the end of 2026, including 2,000 installations along highways. As of March 5, the company says it had already completed more than 4,000 stations.
However, BYD has historically moved more slowly than expected when rolling out ultra-fast charging infrastructure, so how quickly the network expands will be closely watched.
Coming to production vehicles soon
The second-generation Blade Battery isn’t just a concept. BYD says ten production models will be among the first to adopt the technology, including vehicles across its BYD, Denza, and Yangwang brands.
If the real-world charging performance comes close to the company’s claims, BYD’s latest battery could mark a major step forward for EV convenience—bringing recharge times closer than ever to a typical gas station stop.
