96% of China's Chargers Give You Zero 800V Speed Advantage

Описание: 96% of DC chargers in China cannot deliver 800V peak charging speed.
You paid the premium. At 96 out of 100 charging stops, it does nothing.

Four OEMs. Four falsifiable claims. Every one tagged with a confidence level.
Porsche Taycan: CONFIRMED.
Hyundai IONIQ 6: CONDITIONAL — rerate to 239kW, not 350kW.
Xpeng G9: CONDITIONAL — peak is real on S4 network only.
BYD Han EV: MIXED — architecture honest, some marketing not.

Content
— 96%: the infrastructure number that changes everything
— CP-1: Compatible ≠ equivalent (the charger gap)
— CP-2: "Up to 480kW" — what this means at 30% SOC
— CP-3: Why BYD built a boost converter (the real cost signal)
— CP-4: 2–4% range gain, not 10% — the physics
— Verdicts: which OEM to trust, which to pressure
— Fleet procurement framework + monitoring triggers
