BYD ride-hailing models to support flash charging tech

Article >BYD ride-hailing brand Linghui disclosed that the e7 electric sedan will support the recently launched flash charging technology. It will be able to charge from 10% to 97% in nine minutes. The Linghui e7 is a 4.8-meter vehicle with an e-motor for 130 kW (174 hp). >BYD’s ride-hailing sub-brand Linghui was exposed in early January 2026 as the world’s biggest new energy vehicle maker applied for sales licenses for four models. In February, the Linghui brand was officially revealed in China. Shortly after, Linghui shared official images of the e9 BEV sedan and the M9 PHEV minivan. On March 10, BYD revealed that the Linghui e7 sedan will adopt flash charging. Linghui e7 with flash charging >The Linghui e7 was officially unveiled in China as a taxi-oriented battery-electric vehicle. It uses the second-generation Short Blade battery pack, which supports fast DC charging. The new model will be able to charge at BYD’s recently revealed flash charging stations with a maximum output of 1,500 kW per charging connector. >The Linghui e7 sedan will be able to charge from 10% to 70% in approximately five minutes. It will take around nine minutes to charge 10 – 97%. This charging speed applies pressure to the recent CATL battery swap project for low-cost commercial vehicles. CATL’s swap stations store 14 – 30 batteries, capable of performing a replacement in 1.5 minutes. >The battery replacement is still faster than the charging session. However, swap stations have two drawbacks. The first is the high cost of infrastructure development. And the second is the necessity of adapting the cars’ design to battery swap requirements. CATL aims to install 2,500 battery swap stations in China in 2026. Meanwhile, BYD has already deployed 4,239 flash charging stations in China with a plan to establish 20,000 charging stations this year. More about the Linghui e7 >The Linghui e7 follows the design language of BYD’s Ocean series. It has thin headlights, a closed front end, and a single taillight unit. Dimensions of the e7 are 4780/1900/1515 mm. The wheelbase reaches 2,820 mm. For clarity, it is 91 mm longer than the Skoda Octavia. >The entry-level Linghui e7 offers a 100 kW (134 hp) electric motor. Two LFP battery variants are available. Their capacity has yet to be revealed. However, the range was disclosed by the Chinese regulator. The standard e7 will offer 450 km of range, while the long-range variant will boast 520 km of range. CarNewsChina expects the e7 to adopt two battery variants: 51.3 kWh and 61.4 kWh.

My question is - how will it affect the battery?

You'll find out in 20 years. Sooner if BYD is lying. Their 1MW EV has been out for a year. Their 1.5MW sales start next month. In the meantime LFP is up to 10,000 cycles. That's a lot of cycles to sacrifice to fast charging before anyone cares.

I mean, is there any reliable research about it or a qualified opinion? I like how one guy on Twitter posted that crying about "need for nuclear power plant" is wrong, as each Flash charger is equipped with massive batteries.

LFP has been out since the '90s. BYD has been working on LFP every single day for about 20 years now. >is there any reliable research about it or a qualified opinion? Yes. At this point it would be harder to find reliable research or a qualified person to tell you want you think you know about battery life that just came out 5 days ago. Try it. >Their 1MW EV has been out for a year. Try and find someone who proved BYD wrong for a product that has been out for a full year. Then go look up battery recalls on LFP for the past 5 years vs NMC. The cars are selling next month. Just wait. 2026.03.05 Here's the launch video in the meantime. Maybe they mention cycles or which 3rd party lab did the tests. https://www.youtube.com/watch?v=hVFnxc7N-v8

51-61.4 kWh most likely means these are 300-400V batteries. The 10-70% 5 min flash charge speeds work with the newer 800-1000V blade 2 batteries. This is essentially marketing. It means you can plug in these vehichles to a flash charger, but you will get nowhere near the 5min charge times. Lower voltage means higher current needed, porportionally squared to deliver the same charge rate. Higher current means higher heat dissipation and losses. It'll still be relatively fast in terms of what we're used to, but not gas pump speed fast.

BYD has more than 100 thousand engineers, lot of them are doctors, they know what they are doing.

Fun fact : BYD is famous for hiring from tier 2 universities. BYD is similar to Tesla in that they some how were able to to get the right people in the right place working together. Legacy auto couldn't manage that. Amazing what happens when the company lets workers do their thing.

I have seen Chinese taxi with close to 1 million KMs. And taxi EV with 300-400k KMs. The target marget hammer those cars, it show at least confidence.
