BYD Officially Launches the Second-Generation Blade Battery and Flash-Charging Technology

2026-03-15 | Calvin

On March 5, 2026, BYD held the launch event for its second-generation Blade Battery and flash-charging technology at the Shenzhen Universiade Center Stadium. The event, themed “Flash Charging China, Changing the World,” marked a major milestone in the advancement of power battery technology.

After six years of development, the sharpened blade returns.

The second-generation BYD Blade Battery achieves five major technological breakthroughs: flash charging at normal temperatures, flash charging in low temperatures, enhanced safety, extended driving range, and longer lifespan. These innovations comprehensively address key challenges faced by the new energy vehicle industry—such as range anxiety, slow charging, and poor low-temperature charging performance—pushing power battery technology into a new era and leading the global new energy vehicle industry into the age of flash charging.

Today, the electric mobility experience is still affected by several real-world pain points: drivers become anxious when the battery still has half its charge remaining, long queues at charging stations during holiday travel have become common, and charging in low temperatures can be extremely frustrating. These anxieties not only place a heavy psychological burden on users but also lead to significant waste of national copper resources and increased societal costs as infrastructure expands to mitigate the issue. Wang Chuanfu, Chairman of BYD, pointed out: “To solve these persistent problems, we must address them at the root. The fundamental cause of all these issues is slow charging and the difficulty of charging in low temperatures.”

Through a series of breakthrough innovations—including a full-chain lithium-ion ultra-fast conduction technology system, high-throughput electrode reconstruction technology, and an ultra-thin high-strength SEI film—the second-generation Blade Battery establishes a strong performance foundation. It achieves comprehensive excellence across five dimensions: flash charging at normal temperatures, flash charging in low temperatures, superior safety, long driving range, and extended lifespan—creating one of the world’s most advanced power batteries and solving the last major challenges of the electrification era.

Flash Charging at Normal Temperatures: 5 Minutes to Recharge, 9 Minutes to Fully Charge

Thanks to the full-chain lithium-ion ultra-fast conduction technology system, the second-generation Blade Battery delivers unprecedented charging speed under normal temperature conditions. It can charge from 10% to 70% in just 5 minutes, and from 10% to 97% in only 9 minutes—achieving the fastest mass-production charging speed in the world and offering users the ultimate flash-charging experience: “5 minutes to recharge, 9 minutes to full.”

Low-Temperature Flash Charging: Only 3 Minutes Longer at -30°C

With the direct refrigerant cooling and heating technology for power batteries, the second-generation Blade Battery maintains excellent flash-charging performance even in extremely cold conditions. At temperatures as low as -30°C, it can charge from 20% to 97% in just 12 minutes—truly achieving flash charging in extreme cold comparable to that at normal temperatures.

Ultimate Safety Exceeding the New National Standard

The second-generation Blade Battery is equipped with a high-safety “endoskeleton” battery pack structure featuring an integrated high-strength frame for comprehensive protection. This design ensures maximum safety throughout the entire battery lifecycle and completely eliminates user concerns about battery safety.

Through a series of rigorous safety tests that exceed the latest national standards, the Blade Battery once again demonstrates its industry-leading strength:

• World’s first “Simultaneous Flash Charging and Needle Penetration Test”: No thermal runaway, no smoke, and no fire. Even after 500 flash-charging cycles, the battery still successfully passed the simultaneous flash-charging and needle penetration test with no thermal runaway, smoke, or fire.
• Ultra-demanding “Thermal Propagation Test” beyond the new national standard: After simultaneously triggering short circuits in four cells, the battery pack showed no thermal propagation, no fire, and no explosion.
• High-energy “Bottom Impact Test”: In a bottom-impact test with force ten times higher than the new national standard, the battery pack remained stable with no fire and no explosion.

Longer Range: Faster Charging and Greater Distance

The second-generation Blade Battery significantly enhances vehicle driving range. Compared with the previous generation, its energy density increases by more than 5%, enabling pure electric vehicles to achieve ranges exceeding 1,000 km. The new Denza Z9GT equipped with the second-generation Blade Battery can reach a maximum range of 1,036 km.

Long Lifespan: Flash Charging Without Compromising Durability

Technologies such as the ultra-thin high-strength SEI film and dynamically self-repairing electrode interfaces, combined with the creation of a “high-speed lithium-ion channel” and an “all-temperature intelligent thermal management system,” enable the second-generation Blade Battery to generate less heat and dissipate heat more efficiently and evenly. As a result, flash charging has minimal impact on battery lifespan.

The second-generation BYD Blade Battery delivers unprecedented flash-charging speed, ultra-long driving range exceeding 1,000 km, extended lifespan, and safety standards far surpassing the new national benchmark. We firmly believe that, in terms of charging speed, energy density, durability, and safety, the second-generation Blade Battery offers unmatched overall advantages and represents the optimal solution for mainstream passenger vehicle power batteries.

In the past, the wheels that changed the world came from afar; today, the wave that leads the era rises in China. With BYD’s second-generation Blade Battery and flash-charging technology, new energy vehicles officially enter the era of flash charging.
