On March 5, BYD held a launch event titled "Flash Charging China, Changing the World" at the Shenzhen Universiade Center Gymnasium. It officially unveiled: the second-generation Blade Battery and flash charging technology, setting a new global record for the fastest charging speed in mass production—from 10% to 70% in just 5 minutes; from 10% to 97% in just 9 minutes; and at minus 30 degrees, from 20% to 97% in only 3 minutes more than at room temperature. This single move conquered the worldwide challenges of the first half of electrification—"slow charging" and "difficult low-temperature charging"—bringing the first half of electrification to a perfect conclusion. At the same time, it announced the "Flash Charging China" strategy, under which 20,000 flash charging stations will be built nationwide by the end of the year, making charging freer and more convenient for users and ushering new energy vehicle charging into the flash charging era.
At the event, Wang Chuanfu also announced: all owners of flash-charging vehicles equipped with the second-generation Blade Battery will enjoy major "flash charging benefits." Starting from the date of vehicle delivery, they can enjoy 1 year of free flash charging benefits at flash charging stations nationwide, making the flash charging experience even smoother. Moreover, after the free flash charging period ends, it will remain consistent with the industry and will not charge extra fees.
The last "stubborn illness" of the first half of electrification—slow charging and difficult low-temperature charging
At present, the electric travel experience is still troubled by some real pain points: panic when the battery is still half full, long charging lines during holiday travel becoming the norm, and low-temperature charging being even more miserable. These anxieties place a huge psychological burden on users, and efforts to alleviate them also cause enormous waste of national copper resources and social costs. BYD's Wang Chuanfu pointed out: "To treat these stubborn illnesses, we must address the root cause. The root of all problems is slow charging and difficult low-temperature charging."
BYD's second-generation Blade Battery redefines the world's most advanced power battery
To solve these root problems, the key lies in the battery. After six years of sharpening one blade, BYD officially launched the second-generation Blade Battery, bringing a disruptive flash charging experience and achieving "room-temperature charging: fully charged in 5 minutes, fully filled in 9 minutes; low-temperature charging: at minus 30 degrees, only 3 minutes more," making charging as fast as refueling, surpassing the past and unprecedented.
For a long time, "flash charging" and "high energy density" have been widely recognized by the industry as a pair of contradictions. While achieving flash charging, BYD ensured that energy density did not decrease but instead increased, rising by more than 5% compared with the first generation. Combined with lightweight and high-efficiency innovations across the vehicle, the Denza Z9GT equipped with the second-generation Blade Battery achieved a range of 1,036 kilometers.
By creating a "lithium-ion high-speed channel" and a "full-temperature-range intelligent thermal management system," the second-generation Blade Battery achieves lower heat generation and more efficient, uniform heat dissipation, making flash charging have almost no impact on battery life. Based on such confidence, BYD also announced that its battery warranty policy would be further upgraded! The "capacity retention rate" of the second-generation Blade Battery warranty has been increased by 2.5% overall, and the cells still come with a "lifetime warranty." This is the second-generation Blade Battery's reassuring promise to all users.
The second-generation Blade Battery continues to carry safety through to the end. Through a series of safety tests exceeding the new national standards, it creates the safest battery for users, ensuring safety throughout the battery's full lifecycle and completely eliminating users' safety concerns.
BYD's second-generation Blade Battery not only gives users an unprecedented flash charging speed, but also over 1,000 kilometers of ultra-long range, a longer lifespan and a higher warranty policy, and safety far exceeding the new national standards. This is the world's most advanced power battery!
BYD flash charging technology, the most society-friendly charging solution
To achieve the flash charging speed of the second-generation Blade Battery, BYD also newly developed a flash charging pile, with single-gun charging power reaching: 1,500 kW! It is the world's highest-power single-gun mass-produced charging pile! Combined with a super-fast-discharge energy storage system, it breaks through grid capacity limitations and absolutely will not harm the power grid. It is the most society-friendly charging solution.
Announcing the "Flash Charging China" strategy, making the flash charging experience accessible everywhere
Traditional public charging piles have heavy guns, dirty cables, inflexible movement, and cumbersome charging processes. To solve these pain points, BYD's flash charging pile adopts the world's first "slide-rail suspended T-shaped pile" design, letting the cable pull the gun, making the feel very light, almost a "zero-gravity charging gun"; moreover, the gun cable always remains suspended, avoiding tangles and staying cleaner; users can also easily slide it left and right, making charging more flexible. At the same time, BYD has also connected all links between the vehicle and the pile. With a simple setup through the BYD flash charging APP, "plug and charge, seamless payment" can be achieved. This is the most user-friendly charging pile.
In order to build flash charging piles near users more quickly, BYD simultaneously launched the "Flash Charging China" strategy, building flash charging stations on a large scale nationwide, with an estimated 20,000 flash charging stations completed by the end of this year, making flash charging truly spread across all of China.
Among them, BYD will collaborate with operators of charging networks nationwide and accelerate construction through the "flash charging station within a station" model, with an estimated 18,000 stations built by the end of the year. In terms of coverage, flash charging stations will be within 3 kilometers in first- and second-tier cities, within 5 kilometers in third- and fourth-tier cities, and within 6 kilometers in fifth- and sixth-tier cities, ensuring that users can access flash charging services within 5 kilometers in 90% of urban areas, truly laying flash charging stations at users' doorsteps.
In addition, BYD's "flash charging highway stations" will also cover nearly one-third of highway service areas, with an estimated 2,000 completed by the end of this year, achieving an average of one flash charging station every 100-plus kilometers, further solving users' charging anxiety for long-distance travel. BYD also promised that before this year's May Day holiday, the first batch of 1,000 "flash charging highway stations" will be completed, allowing users worry-free holiday travel during May Day.
Subsequently, BYD will also launch the "Dream Station Building" plan for flash charging users. As long as 4 BYD owners propose it at the same time, station planning can be carried out where conditions permit. Wherever user demand is, stations will be built there, and flash charging stations will be open and shared with society as a whole.
The release of the second-generation Blade Battery and flash charging technology, together with the implementation of the "Flash Charging China" strategy, marks that the two major worldwide challenges of "slow charging" and "difficult low-temperature charging" have been conquered, bringing the "first half" of new energy vehicle electrification to a perfect conclusion.
With the original aspiration of three major green dreams, accelerating global electrification development
In 2006, BYD proposed the "three major green dreams," which since then became Wang Chuanfu's lifelong career. After more than ten years of persistence, the dreams of the past have moved step by step toward reality, leading to today's flash charging technology of "integrated solar energy, energy storage, and charging." BYD has always been a company that changes the world with technology. Today, BYD releases the second-generation Blade Battery and flash charging technology, and will once again change the world with technology.
In the future, BYD announced that by the end of 2026, it will implement flash charging stations on a large scale overseas, moving from Flash Charging China toward a Flash Charging Planet, helping global electrification achieve leapfrog development and building Earth into a greener planet! Once, the wheel that changed the world came from afar; today, the tide leading the era is right here in China! BYD's second-generation Blade Battery and flash charging technology will lead new energy vehicles into the flash charging era from now on!
