Why 800V architecture stopped being a spec-sheet flex
Three platforms, three charge curves, one winner at 10–80%. We plotted all three.
Issue 47 · every Thursday
312 mi WLTP. 240 kW peak. We publish the number the brochure rounds off.
Range figures, charge curves, and battery data for buyers who read past the press release. Measured on a bench or logged from a fleet — never copied from a spec sheet we didn't verify.

800V stopped being a spec-sheet flex. Here's the charge-curve proof.
Issue 47 · 5 min
Morning —
Every manufacturer quotes peak kW. Almost none show you the taper. We put three 800V platforms on the same DC charger, same ambient temperature, same 10% starting state of charge, and logged every second.
“The winner held 200 kW+ for six minutes longer than the platform with the higher headline number.”
Three things worth your Thursday:
- The full 0–100% curve for all three, plotted on one axis
- Why the peak-kW spec on the window sticker is close to meaningless alone
- A cold-weather correction table you can apply to any WLTP figure
Drive safe out there.

“Issue 44's adapter voltage-drop numbers changed which cable we spec on 40 vans. Nobody else measured under actual load.”
“I forward the battery degradation issue to every customer asking about used packs. Cited sources, not vibes.”
“The cold-weather range piece matched my own logged data within 2%. First outlet to get that close.”
