BYD Unveils Blade Battery 2.0 and 1,500 kW FLASH Charging That Refills an EV in Nine Minutes
BYD has launched its second-generation Blade Battery and a 1,500 kW FLASH Charging network that can take a compatible EV from 10 to 97 percent in nine minutes, with plans to deploy 20,000 stations across China by year-end and begin overseas rollout.
BYD, the world’s largest electric vehicle manufacturer by volume, has unveiled its second-generation Blade Battery alongside a 1,500 kW FLASH Charging system that the company says can charge a compatible EV from 10 to 97 percent state of charge in just nine minutes. The announcement, made on March 5, represents a significant escalation in the global EV charging race and widens the gap between Chinese and Western charging infrastructure.
Blade Battery 2.0
The updated battery delivers a 5 percent increase in energy density over the original Blade Battery while simultaneously improving charging speed. BYD says the technology resolves what has long been considered a fundamental trade-off between fast charging capability and high energy density.
At the core of the improvement is what BYD calls the FlashPass Ion Transport System, built on three innovations: a Flash-Release cathode with directionally engineered architecture for rapid ion deintercalation, a Flash-Flow electrolyte optimized through AI-driven simulation for high ionic conductivity, and a Flash-Intercalate anode that enables 360-degree lithium-ion intercalation through multi-dimensional insertion sites. According to BYD’s official announcement, the battery also shows 2.5 percent less capacity degradation than its predecessor.
The Denza Z9GT, equipped with the new battery, achieves a claimed range of 1,036 km on China’s CLTC test cycle. Safety testing has also been rigorous: BYD says the battery passed a simultaneous FLASH Charging and nail-penetration test with no thermal runaway after 500 cycles, and survived a forced short circuit reaching temperatures above 700 degrees Celsius without catching fire.
A Charging Network Three Times Faster Than Western Infrastructure
The FLASH Charging stations operate at up to 1,500 kW through a single connector at 1,000 volts. To put that in context, the fastest chargers widely deployed in the United States and Europe typically top out at 250 to 350 kW, with many sites still limited to 150 kW. BYD’s system is more than three times faster than what most Western EV owners can access.
The stations feature a T-shaped overhead design with sliding-rail cable systems that lift connectors away from ground-level contaminants and reduce the physical weight drivers need to handle. Each station integrates an ultra-fast-discharge energy storage system of 200 to 300 kWh per unit, which acts as both a power amplifier and a buffer to prevent grid overload, enabling BYD to deploy high-power charging without requiring costly grid upgrades at every site.
Cold-weather performance is another area BYD has addressed. At minus 30 degrees Celsius, the company says a charge from 20 to 97 percent takes only 12 minutes, just three minutes longer than at room temperature.
Deployment at Scale
BYD has adopted a “station-within-a-station” model, integrating FLASH chargers into existing public charging networks rather than building standalone sites. As of March 5, the company had already installed 4,239 stations across China, with a target of 20,000 by year-end. Of those, 2,000 will be highway stations covering roughly one-third of China’s service areas.
BYD Chairman Wang Chuanfu said the industry must “address the lingering challenge of slow charging speeds and poor low-temperature charging performance” for mainstream EV adoption, according to the company’s press release.
The company has also confirmed plans to begin overseas FLASH Charging rollout by the end of 2026, prioritizing markets where BYD already has manufacturing operations, including Thailand, Brazil, and Hungary. BYD recorded 100,151 overseas unit sales in February 2026, a 41.4 percent year-over-year increase, and has set a 2026 export target of 1.3 million vehicles.
Competitive Implications
The launch underscores the widening technology gap in EV charging infrastructure. Tesla’s Supercharger network, the largest in the West, has deployed roughly 35,000 bays across approximately 3,000 sites over 14 years, operating at 250 to 325 kW. BYD aims to install 20,000 stations in a single year at more than four times the power output.
For Western automakers and charging networks, the challenge is not just matching the hardware. BYD’s integrated approach, controlling the battery chemistry, vehicle platform, and charging infrastructure, allows it to optimize across the entire stack in ways that most competitors, who rely on third-party charging networks and battery suppliers, cannot easily replicate.
