On March 5, 2026, BYD held the “Flash Charging China, Changing the World” launch event at the Shenzhen Universiade Sports Center Stadium, officially unveiling the second-generation Blade Battery and its flash-charging technology. The debut of the flash-charging technology was the most explosive moment of the event.
Based on the second-generation Blade Battery, BYD introduced the Megawatt Flash Charging 2.0 system, with a peak charging power of up to 1500 kW—far exceeding the current mainstream ultra-fast charging standards. The live test results were astonishing: charging from 10% to 70% takes only 5 minutes, and from 10% to 97% takes just 9 minutes. This speed is already very close to, and in some scenarios even surpasses, the refueling time of traditional gasoline vehicles.
In the past, EV users were often criticized for the problem of “slow charging.” Now BYD has achieved a qualitative leap through quantitative breakthroughs—adding 400–500 kilometers of range in just 5 minutes, more than two kilometers of range per second, truly realizing “charging as fast as refueling.” Even in extremely low temperatures of −30°C, charging from 20% to 97% takes only 12 minutes, meaning low-temperature fast charging is no longer a pain point.
More importantly, this technology will not be limited to high-end models. BYD clearly stated that it will rapidly deploy it to mainstream models priced between 100,000 and 200,000 RMB. Combined with the planned 15,000 megawatt flash-charging stations, charging pile utilization rates will increase significantly, approaching or even surpassing the level of gasoline pumps.
The long-standing problems of long queues and low utilization at charging stations will be effectively resolved, transforming the user experience from “just acceptable” to truly satisfying. When charging becomes as convenient as refueling, the core weakness of pure electric vehicles will be completely eliminated. BYD’s technological combination gives electric vehicles a comprehensive advantage over gasoline cars in range, energy replenishment, and safety. This is not an incremental improvement but a revolutionary leap—the era in which pure electric vehicles can fully replace gasoline vehicles has officially begun.

The current electric mobility experience still faces several real-world challenges. Range anxiety caused by low battery levels, long queues at charging stations during holiday travel, and charging difficulties in low-temperature environments not only create inconvenience for users but also lead to the consumption of national copper resources and increased social costs.
BYD Chairman Wang Chuanfu pointed out that slow charging and the difficulty of charging in low temperatures are the key breakthroughs needed to solve these issues.

The core of BYD’s second-generation Blade Battery lies in the comprehensive evolution of its technological architecture. It continues to use the lithium iron phosphate (LFP) chemistry system, but by introducing a lithium manganese iron phosphate composite cathode material, a silicon-carbon anode, and optimized cell structures, the system energy density has increased significantly to 190–210 Wh/kg—an improvement of about 36–40% compared with the first generation.
This leap directly brings ultra-long driving ranges: vehicles equipped with the second-generation Blade Battery can easily exceed 1,000 kilometers of CLTC pure electric range. For example, the first launch model Yangwang U7 reaches 1006 kilometers, while the Denza Z9GT even achieves 1036 kilometers. This means pure electric vehicles can finally bid farewell to “range anxiety” during long-distance travel.
Even more impressive is the low-temperature performance: in extreme conditions of −30°C, the battery discharge efficiency remains above 80%, and capacity degradation is controlled within 15%, meaning winter range will no longer be drastically reduced. Fast-charging capability is equally outstanding, supporting high-rate charging and discharging. Combined with the full-domain 1000V high-voltage platform, charging efficiency far exceeds the industry average.

Safety is the soul of BYD’s Blade Battery, and the second-generation product continues and strengthens this advantage. After being left idle for two hours and undergoing 500 flash-charging cycles, the battery can still safely pass the nail penetration test. Even when four cells are simultaneously short-circuited to trigger a thermal propagation test, there is still zero thermal runaway. Its impact resistance exceeds national standards by more than ten times, ensuring that even in extreme collisions it will not catch fire or explode.
This “super-safe lithium iron phosphate” characteristic provides a solid foundation for the subsequent super flash-charging technology. Without a reliable safety baseline, even the fastest charging would be meaningless. The second-generation Blade Battery truly achieves “fast, safe, and durable,” upgrading lithium iron phosphate from a “low-cost alternative” into a “high-end mainstream choice.”
The second-generation Blade Battery creates a “high-speed lithium-ion channel” and an “all-temperature intelligent thermal management system,” achieving lower heat generation and more efficient, uniform heat dissipation, thereby reducing the impact of flash charging on battery life. Based on this, BYD has upgraded its battery warranty policy: the “capacity retention rate” under the warranty of the second-generation Blade Battery has been increased by 2.5%, and the battery cells still come with a lifetime warranty.
To match the flash-charging speed of the second-generation Blade Battery, BYD has developed a new flash charging pile with a single-gun charging power of up to 1500 kW. Combined with a super-fast discharge energy storage system, it can overcome power grid capacity limitations while adapting to grid usage requirements.

To address issues with traditional public charging piles—such as heavy charging guns, dirty cables, limited flexibility, and complicated charging procedures—BYD’s flash charging pile adopts the world’s first “sliding rail suspended T-type pile” design. This reduces the perceived weight of the charging gun during operation, keeps the cable suspended to avoid tangling and improve cleanliness, and allows it to slide left and right to enhance flexibility during charging.
In addition, BYD has connected the vehicle and charging station systems. Through the BYD Flash Charging App, users can easily set up “plug and charge with automatic payment,” making the process seamless and effortless.
To accelerate the deployment of flash charging stations, BYD simultaneously launched the “Flash Charging China” strategy, planning to complete 20,000 flash charging stations nationwide by the end of 2026.
BYD will collaborate with national charging network operators and promote construction through a “station within station” model, with an estimated 18,000 stations to be completed by the end of the year. In urban areas, flash charging stations will be deployed within 3 km in first- and second-tier cities, within 5 km in third- and fourth-tier cities, and within 6 km in fifth- and sixth-tier cities, ensuring that users in 90% of urban areas can access flash charging services within a 5 km radius.
On highway networks, BYD’s “Flash Charging Highway Stations” will cover nearly one-third of highway service areas, with about 2,000 stations expected to be completed by the end of the year, achieving an average spacing of slightly over 100 kilometers between stations. The first batch of 1,000 highway flash charging stations is planned to be completed before the May Day holiday in 2026.
In the future, BYD will launch the “Dream Station Building” program for flash charging users. When four BYD vehicle owners jointly request the construction of a station and suitable site conditions are met, a flash charging station will be planned and built. These stations will be open and shared with the entire public.
The launch of the second-generation Blade Battery and flash charging technology, together with the implementation of the “Flash Charging China” strategy, will help solve industry problems such as slow charging and difficulties in low-temperature charging, completing the technological breakthroughs in the first stage of new energy vehicle electrification.
In 2006, BYD proposed its “Three Green Dreams.” After years of research, development, and practical implementation, the company has realized the integration of solar power, energy storage, and charging through its flash-charging technology. The launch of the second-generation Blade Battery and flash charging technology represents another major technological achievement for BYD in the field of electrification.
BYD plans to scale up the deployment of flash charging stations overseas by the end of 2026, expanding from “Flash Charging China” to “Flash Charging Planet,” supporting the global development of electrification and promoting the construction of a greener, low-carbon mobility ecosystem.
