- BYD introduced a next-generation EV battery capable of charging from 10% to 70% in just five minutes.
- A nationwide ultra-fast charging network is planned across China with 20,000 stations by 2026.
On March 5 in Shenzhen, BYD unveiled the BYD Blade Battery 2.0 alongside its new FLASH Charging technology, aiming to resolve some of the most persistent electric vehicle usability challenges. The innovation targets key pain points such as long charging times, queues at public charging stations during holidays, and performance limitations in extremely cold weather conditions.
At room temperature, the battery enables exceptionally rapid charging performance, allowing vehicles to charge from 10% to 70% state-of-charge in just five minutes and from 10% to 97% in nine minutes. Even under extreme conditions of minus 30 degrees Celsius, the battery can charge from 20% to 97% in approximately twelve minutes, only slightly slower than charging at standard temperatures.
Performance Improvements and Vehicle Range
The new battery generation delivers roughly 5% higher energy density compared with the previous version. Combined with vehicle weight optimization and drivetrain efficiency improvements, the technology significantly increases driving range. The Denza Z9GT SUV equipped with the battery demonstrates a range of up to 1,036 kilometers under test conditions.
The system also integrates the FlashPass lithium-ion transport architecture together with a full-temperature intelligent thermal management system. These solutions reduce heat generation during rapid charging and distribute heat more evenly, enabling sustained ultra-fast charging while minimizing long-term impact on battery lifespan.
FLASH Charger and Infrastructure Development
To support the battery’s charging capabilities, BYD developed the FLASH Charger system capable of delivering 1,500 kW through a single connector, the highest power output currently available among mass-produced single-connector charging stations.
The charger features a distinctive T-shaped overhead design that improves usability while reducing equipment weight. Integration between vehicles and charging stations enables seamless plug-and-charge functionality and automated payment through a mobile application, eliminating manual authentication steps.
Nationwide Charging Network Strategy
To enable large-scale adoption of the BYD Blade Battery 2.0, the company is rapidly expanding FLASH Charging infrastructure across China. As of March 5, a total of 4,239 stations had already been constructed, with a long-term target of 20,000 operational stations by the end of 2026.
- Approximately 18,000 stations will be deployed in partnership with national charging operators through a “station-in-station” deployment model.
- Coverage planning targets one station every 3 km in first- and second-tier cities, every 5 km in third- and fourth-tier cities, and every 6 km in smaller cities.
- FLASH Charging access will be available within a 5 km radius for roughly 90% of urban areas.
- Nearly one-third of China’s expressway service areas will receive high-power stations.
The expressway deployment strategy includes around 2,000 stations by 2026, with one station roughly every 100 kilometers along highways. The company also plans to complete the first 1,000 expressway stations before the 2026 International Workers’ Day holiday and expand FLASH Charging stations internationally before the end of 2026.
