38 days. That is how long remains before Wang Chuanfu’s first verifiable ultra-fast charging infrastructure commitment lands on a hard public date. 4,597 stations are confirmed operational across 279 cities — but the split between highway and urban stations has never been disclosed, and no operator has published what a non-OEM vehicle actually receives at a cross-brand charger. This audit examines four challenge points derived directly from official announcements as of March 28, 2026.
Every claim in this report carries exactly one confidence tag. {VER} = independently sourced. {CLM} = manufacturer or official claim, not independently confirmed. {INF} = engineering inference. {GAP} = data does not publicly exist.
[evp_confidence_bar verified=”18″ claimed=”24″ inferred=”9″ gap=”6″]CP-01: OEM Ultra-Fast Network Station Counts — What “Built” Actually Means
BYD: 4,597 Flash Charging stations in 279 cities as of March 13, 2026 {CLM — Xinjingbao, March 13}. Geely: 2,103 stations in 215 cities, 1,216 of which are ultra-fast {CLM — Dongchedi, March 9}. BYD has officially confirmed the network is “fully open for sharing across all brands; all EV models meeting GB standards can connect and charge normally” {CLM — Dongchedi, March 9, citing BYD official}.
The audit question is not whether these numbers are real. It is what they mean for a vehicle that is not the network owner’s own brand. Three structural gaps sit between “built” and “available at peak power for your vehicle.”
Gap Layer 1 — Physical connection: confirmed open for BYD network, GB/T compatible {CLM}. Gap Layer 2 — Power negotiation ceiling: not a single operator has published the power curve a non-OEM vehicle actually receives. Gap Layer 3 — Geely network access policy: no equivalent official open-access statement found as of March 28 {GAP}.
Geely’s published “2,103 ultra-fast stations” headline is a common misreading. The audit-correct figure is 1,216 — 42.2% of the 2,103 total are standard, not ultra-fast charging {INF — calculated from CLM source data}.
As of March 28, 2026, no proprietary ultra-fast charging operator has published actual charging power curves for non-OEM vehicles on their network. BYD confirmed physical access. What has not been published is the power a non-OEM vehicle actually receives. Fleet operators cannot calculate expected charging time for cross-brand sessions. Procurement decisions that treat 9 minutes as the operational figure for non-OEM vehicles are built on an assumption, not a measured number.
CP-02: Cross-Brand Charging Speed Fragmentation
BYD’s position on open access is clear {CLM}. The core audit question has shifted from whether you can connect to what you actually receive. The audit applies a scenario model until T2 data resolves this: moderate scenario (75% power = approximately 12 minutes for a non-OEM vehicle at a BYD Flash Charger); conservative scenario (60% power = approximately 18 minutes) {INF — engineering scenario from CLM source data}.
Zeekr 001 was independently measured at 1,266.4 kW peak at a Geely ultra-fast charger {CLM — Yiche, March 4, 2026}. BYD Flash Charger single-gun peak: 1,500 kW {CLM — Securities Star, March 4, 2026}. What a non-Geely vehicle receives at a Geely station: DATA NOT AVAILABLE {GAP}. What a non-BYD vehicle receives at a BYD station: DATA NOT AVAILABLE {GAP}.
CP-03: BYD May Day Highway Station Commitment — Execution Pace
Wang Chuanfu publicly committed to 1,000 highway Flash Charging stations operational before May 1, 2026 {CLM — Jingji Ribao, March 6, 2026}. 38 days remain from data cutoff. The audit calculates the current build trajectory against that commitment.
Stations at launch March 5: 4,239 {CLM}. Stations March 13: 4,597 in 279 cities {CLM — Xinjingbao}. Net additions in 8 days: 358 {INF}. Implied monthly build rate: approximately 1,344 stations/month {INF}. Required rate to reach 20,000 by December 31: approximately 1,621/month {INF}. Current shortfall: 17% below required pace {INF}.
Critical caveat: the station-in-station model applies to the 18,000 urban stations. Highway stations require separate approval from state-owned highway service area operators — a structurally longer chain. The May Day commitment specifically tests the harder segment {INF}.
BYD has not separately disclosed the urban/highway breakdown in any public filing or press release. The May Day 1,000 highway station commitment cannot be independently tracked before May 1. There is no partial verification path. The only data point will be BYD’s own official announcement on or around that date.
CP-04: Fragmentation Cost Impact on Fleet TCO
The fragmentation premium is quantifiable. The audit model: 60-vehicle intercity fleet, charging 40% of sessions off-OEM network, non-OEM power scenario 75% of OEM benchmark (12 minutes vs. 9 minutes). Estimated annual fragmentation cost: RMB 295,200–346,000 {INF — scenario model; actual figure subject to T2 recalibration}.
The highest-weight variable is not the power degradation magnitude — that is outside operator control. It is the frequency of off-OEM charging sessions, which is an operator routing and dispatch decision. Reducing off-OEM charging frequency from 40% to 10% cuts the fragmentation premium by approximately 75% — from approximately RMB 295,000 to RMB 74,000 annually {INF}. This action requires no technology change. It is available today.

Data Gap Summary
No equivalent official open-access statement found for Geely network in public reporting as of March 28, 2026. Until confirmed otherwise, Geely ultra-fast network should be treated as OEM-exclusive for non-Geely fleet planning. Monitoring Trigger T8.
