The Q2 2026 Test That Resolves the Biggest Unknown in Ultra-Fast Charging

Sometime between mid-May and mid-June 2026, an automotive media outlet will publish a charging test that changes every TCO model in this audit. It will be the first independent data point for a non-BYD vehicle charging at a BYD Flash Charger — or a BYD Gen 2 vehicle charging at a non-BYD charger — under real-world delivery conditions. The cross-brand power curve gap that currently forces all fleet managers to use scenario estimates will have a measured number.

Why This Test Hasn’t Happened Yet

Ti3 went on sale March 13, 2026 {CLM — Fang Cheng Bao official}. Real-world deliveries to first users are expected within 30–60 days of that date. Independent automotive media (Dongchedi, autohome, Yiche) typically publish independent charging tests within 60–90 days of first deliveries. The limiting factor is time — vehicles have not been in user hands long enough for independent testing at meaningful scale.

What the Test Will Reveal

The T2 trigger test will produce one of three data points: a non-OEM vehicle at a BYD Flash Charger (resolves the cross-brand power gap from the BYD network side); a BYD Gen 2 vehicle at a non-BYD charger (resolves the reverse cross-brand question); or ideally both. The 12–18 minute estimate {INF} will become a measured number.

Trigger-02: Cross-Brand Charging Speed Test -- DATA NOT AVAILABLE to Unlocked

Data Gap

Manufacturer Claim

Non-OEM vehicle on BYD Flash Charger: actual charging power curve -- DATA NOT AVAILABLE [?]. BYD Gen 2 vehicle on non-BYD charger: actual charging power curve -- DATA NOT AVAILABLE [?]. BYD power tier policy for non-OEM vehicles -- DATA NOT AVAILABLE [?]. Current planning estimate: 12--18 minutes for non-OEM vehicles at BYD Flash Charger (moderate/conservative scenario) [I]. Annual fleet fragmentation premium at 40% off-OEM frequency: RMB 295,200--346,000 -- scenario model [I].

Engineering Reality Official claim only

T2 trigger: first independent media test of non-OEM vehicle at BYD Flash Charger OR BYD Gen 2 at non-BYD charger. Expected: Q2 2026, within 60--90 days of Ti3 March 13 on-sale date. Likely source: Dongchedi / autohome / Yiche independent test program. Impact: resolves DATA NOT AVAILABLE gap to measured number. Recalibrates CP-02 verdict from scenario estimate to confirmed figure. Updates CP-04 fleet TCO fragmentation model from scenario to measured cost.

? Data Gap T2 expected Q2 2026. Until then: use 12--18 min planning range, label all TCO models as estimate pending T2, build both moderate and conservative scenarios.

How to Prepare Before the Data Arrives

Every TCO model built before T2 carries a flagged estimate. Build two TCO scenarios (moderate: 12 minutes for non-OEM vehicles; conservative: 18 minutes), label both as scenario estimates pending T2, and identify the breakeven point — the cross-brand charging time at which the fleet deployment remains economically viable.

For BYD-only fleets: T2 does not affect your model. Your 9-minute figure is independently verified {VER}. For non-BYD fleets on BYD network access: the dispatch-policy action (reduce off-OEM charging frequency from 40% to 10%) is available today and does not depend on T2 data.

Q2 2026 Checkpoint: First Independent Cross-Brand Charging Test

Monitor: Dongchedi, autohome, Yiche independent test publications from May 2026 onward. Look for: Ti3 test at non-BYD charger; or non-BYD vehicle test at BYD Flash Charger. This data point recalibrates CP-02 from DATA NOT AVAILABLE to a measured number and updates all fleet TCO models referencing cross-brand charging speed.
