Months after losing its position as the leader among independent brands, BYD has revealed its trump card.
Once reserved as flagship exclusives by automakers, the thousand-kilometer range and megawatt-level supercharging have now been brought by BYD into the mass market at the 150,000 yuan level. On March 5th, BYD officially launched the second-generation blade battery and flash charging technology system, unveiling 11 new models simultaneously, covering four major brands and ranging from the 100,000 yuan to the million-yuan segment. Thus begins a technological battle for battery and recharging equality.
Many industry professionals have noted that BYD's actions are much faster than expected. Just two months ago, Geely ended BYD’s record of 40 consecutive months as the monthly sales champion among Chinese brands. At the start of the year, the decline in new energy vehicle purchase subsidies and the off-season during Spring Festival put BYD’s sales under pressure for two consecutive months, and Geely replaced BYD as the domestic market leader.
For a company used to leading, the significance of “disruptive technology” is self-evident. At the launch event, BYD Group Chairman and President Wang Chuanfu declared: “No one understands batteries better than BYD.”
The capital market was the first to respond. After BYD announced the event on March 2nd, its A-share price surged more than 8% in a single day, with its market capitalization increasing by tens of billions of yuan. However, ultimately, the excitement in share price needs to be backed up by product strength. In the second half of China’s new energy race, now dominated by technological competition, BYD’s play will determine if it can reclaim what it has lost.
Breaking the Deadlock
To understand the significance of this launch, it’s necessary to go back to 2020.
At that time, the first-generation blade battery emerged, making BYD Han EV a hit due to its safety of “no fire when pierced by a needle.” Wang Chuanfu personally showcased the needle test—when a steel needle pierced the battery cell, there was no fire or smoke, becoming a landmark event in the industry. But the shortcomings of the first generation were also obvious—its energy density still lagged behind ternary lithium batteries, limiting maximum range.
Six years later, BYD aims to fill this gap.
The focus of this launch is the second-generation blade battery. According to official information, the new battery adopts a lithium manganese iron phosphate material route, with system energy density upgraded to 190–210Wh/kg, about a 40% improvement over the first generation.
Low-temperature performance is equally key: winter range attenuation is controlled within 15%, and capacity retention at -20℃ surpasses 85%. This is far better than traditional ternary lithium batteries, where attenuation is 25%–35%. At the event, Wang Chuanfu stated the second-generation blade battery not only brings flash charging but delivers comprehensive upgrades.
The 2026 Yangwang U7 is the first to carry a 150kWh battery pack, with a CLTC pure electric range of 1006 kilometers. This means the lithium iron phosphate technology route officially enters the “thousand-kilometer club,” breaking the previous industry norm that only ternary lithium models could reach this threshold. The new Denza Z9 GT achieves a range of 1036 kilometers, setting the global record for longest mass-produced electric range.
If long range solves range anxiety, flash charging solves recharging anxiety.
The simultaneously launched megawatt flash charging 2.0 brings peak power to the 1500kW level, featuring a fully liquid-cooled charging cable weighing just 2kg, compatible with all platform models at 400V, 800V, and 1000V.
At the event, Wang Chuanfu gave key data: Second-generation blade batteries can charge from 10% to 70% in just 5 minutes, from 10% to 97% in only 9 minutes. He explained: “The remaining 3% is specifically reserved for brake energy recovery, which is more conducive to reducing vehicle energy consumption.” At -20℃, charging from 20% to 97% takes less than 12 minutes.
The official claim is: "Charging for 5 minutes adds over 400 kilometers of range." According to actual test data, the Denza Z9 GT equipped with the second-generation blade battery drove a total of 1007 kilometers, with 93 kilometers of range remaining; the Yangwang U7 drove a total of 1005.7 kilometers, with 87 kilometers remaining, completing a 988-kilometer round trip on Hainan Island's tourist highway.
Regarding infrastructure timelines, Wang Chuanfu announced that by the end of 2026, BYD will have built 20,000 flash charging stations and 2,000 flash charging highway stations, covering nearly one-third of highway service areas.
But what really pressures the industry is not any single technology itself, but the breadth and speed of BYD’s tech deployment. Wang Chuanfu stated that the second-generation blade battery will go into mass production and be installed immediately, starting with 10 model variants.
From the lineup at the launch event, ten models appeared together: Yangwang U7 (150kWh/1006km range), Denza Z9 GT (up to 1036km range, new single-motor rear-wheel-drive version, tri-motor version with 850kW total power), Song Ultra EV (150,000–200,000 yuan range, standard lidar + urban NOA, 710km range), Seal 07EV (705km range, standard lidar), Fangchengbao Titanium 3 Flash Charge Version, Titanium 7 EV Flash Charge Version, Datang (7-seat flagship SUV, benchmarked against Li Auto L9/Aito M9), Sealion 06, as well as Yangwang U8, U8L, etc. Among them, Seal 07EV was directly launched that day, while Song Ultra EV and Denza Z9 GT began pre-sales on the same day.
Clearly, BYD’s strategy is not a single-point breakthrough, but a systematic rollout. The second-generation blade battery and flash charging technology are ready for mass production at scale across all brands and price segments. Ministry of Industry and Information Technology data show BYD is even deploying lidar in entry-level models like the Seagull (A00 class), with aggressive moves toward smart driving equality.
Launching this technological offensive at this juncture, BYD’s strategic intent is clear: not only to capture market share within new energy vehicles, but to accelerate the final replacement of gasoline cars.
Counterattack
According to BYD’s official production and sales bulletin, sales of new energy vehicles in February were 190,190 units, of which passenger vehicles sold 187,782 units and overseas exports again surpassed 100,000 units.
Total sales in the first two months were about 400,000 units, a year-on-year decrease of 35.8%. Meanwhile, during the same period, Geely maintained growth in the domestic market by balancing oil and electricity, leading for two consecutive months. This dynamic raises a sharp industry question: Is BYD’s “stall” merely cyclical fluctuation, or a structural turning point?
The direct trigger for the change in sales leadership was a sudden policy shift.
Starting January 1, 2026, new energy vehicle purchase tax will be cut from full exemption to half exemption, at a 5% rate, with a maximum tax reduction of 15,000 yuan per vehicle—the largest scale-down in over a decade. With the policy cliff plus the Spring Festival off-season, January’s national monthly retail of new energy vehicles fell about 20% year-on-year, penetration dropped to 36.25%, even lower than 38.37% in the same period of 2025.
But why did BYD suffer more than others, when the policy reduction applies equally to all new energy automakers?
Industry insiders point out the root cause is product structure. Since BYD fully ceased gasoline car production in 2022, all sales depend on new energy vehicles, with no gasoline business to hedge policy volatility. Geely, by contrast, stabilized its base by balancing oil and electricity, and its Zeekr brand saw sales double.
China Passenger Car Association Secretary General Cui Dongshu noted that, due to purchase tax policy adjustment, new energy passenger car sales in early 2026 will drop at least 30% quarter-on-quarter. He added that automaker competition has shifted from “who is cheaper” to “who can offer stronger technology within the mainstream price range.”
Another reality is that while facing domestic pressure, BYD’s overseas performance is strong.
BYD’s production and sales bulletin shows that in February, exports of passenger vehicles and pickups surpassed 100,000 units for two consecutive months, with cumulative exports over 200,000 units in the first two months. Overseas sales now account for nearly half its total sales, making BYD a main force behind China’s new energy wave abroad. But the overseas market is no greenhouse; Chery, SAIC, and Great Wall’s exports are also surging, and competition has expanded from domestic to global.
It’s at this delicate moment of domestic cooling and overseas heating that the March 5th technology launch carries strategic significance far beyond technology itself.
From an industry competition standpoint, the event embodies "technological equality"—systematically extending features like ultra-fast charging, thousand-kilometer range, and advanced smart driving, previously reserved for models above 250,000 yuan, down to the 150,000–200,000 yuan mass-market segment in China. This delivers a dimension-reducing blow to similarly priced rivals: gasoline cars’ cost-performance advantage is further squeezed, and other new energy brands’ technological moats in this segment are at risk of being leveled out.
Of course, technological deployment needs time to be verified. From the 10 models’ debut to full delivery, and from 15,000 planned flash charging stations to actual coverage, there are uncertainties in execution. Geely won’t sit still; its Galaxy series and Zeekr brand are also rapidly iterating in intelligence and powertrains, while Changan, GAC, Leapmotor, and others have their own aces. 2026 is destined to be a brutal elimination game with technological arms race and price war running side by side in China's new energy market.
Can BYD reclaim the monthly sales crown through this technological offensive? In the short term, suspense remains. The impact of purchase tax reduction is still digesting, and ramping up production for new models will take several months.
But from a mid- to long-term perspective, what BYD demonstrates this time is not just a single technical breakthrough, but a systematic technological output capacity—from battery materials to energy infrastructure, from smart driving algorithms to rapid deployment across all brands and price ranges. As Cui Dongshu said, the key to automaker competition has shifted from price to technology. Only companies holding core technology can define the next era.
The second half of new energy vehicle competition has officially begun. The seeds have been planted, and market testing has only just started.
