800V fast charging will rapidly penetrate new vehicles in 2025 and accelerate its popularization by 2026

A clear trend in 2025 is that 5C fast charging for batteries has become a highly frequent term.
Initially, 5C fast charging was implemented by Li Auto and CATL on the MEGA,(charging rate ≥5C, typically achieving 400-500km range replenishment in 10-15 minutes).
By 2025, it has become a standard or premium option for many mainstream automakers, based on 800V high-voltage platform fast-charging batteries(e.g., Kirin Battery, Shenxing Battery, Gold Brick Battery, Giant Whale Battery, etc.).
BYD has further introduced megawatt-level flash charging(up to 10C), and has also applied fast charging to large-battery extended-range systems. 800V+5C has become a hallmark of extended-range technology, which is somewhat exaggerated.
For electric vehicles, range and charging efficiency are key considerations for consumers. By 2025, with the construction of charging stations, consumers no longer have range anxiety, but ultra-fast charging efficiency has become a competitive tool.
With the price reduction of SiC modules, high-voltage fast charging offers higher energy utilization efficiency, a larger fast-charging range, and relatively lower costs. Any pure electric product priced above 200,000 yuan that does not adopt an 800V high-voltage + fast-charging architecture is somewhat outdated.
Let’s look at this year’s developments:
◎ XPeng has brought 5C down to below 200,000 yuan. The 2025 XPeng G6: 5C ultra-fast charging AI battery as standard, 450km range replenishment in 10 minutes, starting price around 170,000-200,000 yuan. Later, the 2025 XPeng G9, XPeng G7, and 2025 XPeng P7+ will also offer 5C versions.
◎ Li Auto’s i8 and i6 support 5C fast charging, with both ternary and lithium iron phosphate batteries supported.
◎ ZEEKR’s 2025 ZEEKR 007 and 001 also focus on 4/5C and 800V.
◎ Voyah Zhiyin: A 200,000-yuan pure electric SUV, all models support 5C.
◎ Arcfox Alpha T5, a mid-size SUV priced at 160,000-200,000 yuan, supports 5C Shenxing Battery, 500km range replenishment in 15 minutes.
◎ Chery’s Exlantix ET/ES partially supports Shenxing 5C Battery.
Although Tesla still insists on a 400V system, over 30 Chinese automakers have adopted 800V models, with 800V new energy vehicle sales reaching a market penetration rate of 14%.
800V models are accelerating their penetration from the mid-to-high-end segment (above 200,000 yuan) to the mainstream segment (below 200,000 yuan). From 2022 to 2023, the main sales price was above 200,000 yuan, with about 75% above 250,000 yuan, while the proportion of models below 200,000 yuan has increased to 32.5%(26.6% for 150,000-200,000 yuan, 5.9% for 100,000-150,000 yuan).
Note: If we remove 5C (5C battery cells are still expensive), purely looking at fast charging, the 2026 Leapmotor C10 pure electric version is equipped with an 800V high-voltage platform and silicon carbide technology, effectively bringing 800V into the 100,000-150,000 yuan price range.
Therefore, in 2026, we see that with price constraints, automakers will rapidly advance urban NOA and 800V+3C fast charging deployment rates through the configurations below. Of course, the actual experience is limited by the proportion of fast-charging stations, but it is indeed a process of increasing costs slightly to attract consumers.
