BYD has 4,597 Flash Charging stations open to all GB-standard EVs {CLM}. The question they have not answered: what power does a non-BYD vehicle actually receive at those stations? This data should exist. It has not been published by any operator.
What Data Is Missing
No proprietary ultra-fast charging operator — BYD, Geely, or any other — has published actual charging power curves for non-OEM vehicles on their network. BYD confirmed open physical access on March 9, 2026 {CLM — Dongchedi, citing BYD official}. BYD Flash Charger peak: 1,500 kW single gun, 400V–1,000V voltage range {CLM — Securities Star, March 4, 2026}. What that hardware delivers to a non-OEM vehicle: absent.
The gap exists at two levels. First: access policy (confirmed open for BYD network). Second: power allocation policy — does firmware allocate identical, reduced, or differentiated power to non-OEM vehicles? That policy has not been published, and the open-access statement does not address it.
Why This Data Should Exist
The physical infrastructure is deployed and in operation. BYD Gen 2 vehicles have been charging at BYD Flash Chargers since March 5, 2026 {CLM}. Non-OEM GB-standard EVs have presumably connected to BYD Flash Chargers since open-access confirmation on March 9 {CLM}. Charging session power data exists in BYD’s firmware logs. The reason it has not been published is commercial, not technical.
Impact on Fleet TCO Models
A 60-vehicle intercity fleet that charges 40% of sessions off its OEM’s network cannot calculate the energy cost or time cost of those sessions without this data. The audit uses a moderate scenario (75% of OEM power = approximately 12 minutes) as the planning estimate {INF}. The annual fragmentation premium under this estimate: approximately RMB 295,200–346,000 for a 60-vehicle fleet {INF — scenario model}. Fleet managers should flag this item in every TCO model as “estimate subject to revision on T2 trigger.”
When This Gap Is Expected to Close
Ti3 at RMB 153,800 went on sale March 13, 2026 {CLM}. Real-world user delivery is expected within 30–60 days of that date. Independent media tests (Dongchedi, autohome, Yiche) typically publish within 60–90 days of on-sale date. The first independent data point for a non-BYD vehicle at a BYD Flash Charger is the Q2 2026 monitoring trigger T2. This is the single most decision-relevant data point expected in Q2 2026.
No proprietary ultra-fast charging operator has published actual charging power curves for non-OEM vehicles on their network as of March 28, 2026. Physical access is confirmed for BYD network {CLM}. Power allocation policy is not addressed by the access confirmation. Use 12–18 minutes as the planning range for non-OEM vehicles on BYD Flash Charger. Revise all TCO models when T2 data is published.
