Flagging one figure worth double-checking: the Han L's 1,000 kW Super e-Platform charging claim is real but it's a peak number under specific conditions, not a sustained rate — BYD's own published curve tapers hard past 50% SoC like every other flagship fast-charging platform. The "250 miles in five minutes" claim in the piece is technically accurate for the first few minutes of a low-SoC charge, not a five-minute full session. Worth being precise about since it's the kind of number that gets repeated without the asterisk.
Checked current importer listings against the $55-75/cell figure in this piece and it holds up as of this week, though the range is wide depending on quantity and importer. Availability is still thinner than LFP — expect fewer vetted suppliers and less per-cell test data included with shipments compared to the mature EVE/REPT pipeline. Chemistry looks solid. Supply chain is still catching up to LFP's maturity.
FMVSS 305 and 305a adapted for conversions is the sensible starting point. The isolation resistance minimums and thermal runaway venting requirements are the technically substantive parts — these are the failure modes that cause serious injuries in EV fires, and a conversion that buries a pack in a vehicle structure not originally designed for it needs to meet at least the same standard as an OEM EV on those specific points.
The certification pipeline being backlogged as August approaches is a significant warning. EU-accredited third-party verification bodies have finite capacity. Companies that wait until June or July to engage will find waitlists that push them past the deadline. Early engagement is the only answer — the article is right to flag this explicitly.
The Supercharger retrofit requirement is what will actually change the charging landscape. Tesla NACS-only stations opened after 2024 need CCS adapters or multi-standard cables by January 2027 to stay eligible for state funding. Tesla has been expanding aggressively in California with state money — this is the CPUC using that funding relationship as leverage for interoperability. Straightforward policy mechanism.
The ASE L3 Light Duty Hybrid/Electric Vehicle Specialist certification alongside A6 Electrical/Electronic Systems is the credential stack worth understanding. Ford and GM training partnerships at community colleges are valuable for equipment access, but the portable credential employers recognize is the ASE certification — not the manufacturer's internal program completion certificate.
Worth being precise about what BYD's nail-penetration result actually demonstrates versus what gets implied in secondhand summaries. The published test is no fire, no smoke, surface temperature staying in a narrow band — that's a real, meaningfully better result than a typical prismatic LFP cell under the same test. What it doesn't demonstrate is anything about long-term degradation, calendar aging, or performance in a stationary duty cycle, because that was never the test. Citing the crash-safety data as if it settles the "which cell for home storage" question is citing the right data for the wrong question.
The 12–24 month utility interconnection timeline for stations above 150 kW explains most of the rollout delay. The permitting and procurement timelines for the stations themselves are manageable; it's the utility-side infrastructure upgrades that can't be compressed. This is a grid infrastructure problem as much as a DCFC deployment problem.
The 94–97% round-trip efficiency figure for LFP at moderate charge/discharge rates matches published EVE LF280K spec data. The first-year 96–98% capacity retention estimate is consistent with formation loss data from EVE's published characterization sheets. Nothing in the performance section is optimistic — it reads as accurate to the spec.
The Form 5695 hasn't been updated yet per the article — attach a written statement citing Notice 2026-31. I'd recommend keeping the original component invoices, the cell spec sheets (so the IRS can verify kWh capacity), and your BMS datasheet in one folder. The 3 kWh minimum is easy to hit even on small builds.
