800 V charging — the P7+ strongest asset

The 800 V architecture is the XPENG P7+ strongest asset, confirmed repeatedly in tests and by owners.
What tests say
- Peak charging ~400-450 kW — measured 350-400 kW in practice (Bjørn Nyland, ELEKTROBAYS, Move Electric).
- 10-80% in about 12 minutes on a >=350-400 kW charger; many reviewers measure 12-14 min.
- The charging curve holds high power well above 80%.
- LFP battery — safe to charge to 100%, high cycle durability.
- Downside: AC charging only 11 kW (no 22 kW) — matters for home charging.
What owners say
- “17% to 77% in exactly 10 minutes”.
- “The XPeng charges faster at 88% than my Model Y at 50%“.
- “300 km of range after about 10 minutes at mild temperatures — simply great” (translated from German).
- Comparison: “17 to 91 SOC: XPeng P7+ 16.5 min vs Tesla Model Y ~43 min”.
Long-distance test
- Peak 399 kW; on a 300 kW station it holds ~300 kW for a long time.
- 10-80% in ~14:50 (record 13 min); 7-90% in 19 min, average 222 kW.
- Rule of thumb: 300 km -> 12 min charging, 350 km -> 14 min.
- Power dips (down to ~174 kW) — suspected hot battery or non-water-cooled cable.
Bottom line: if you drive long routes, P7+ charging is in a class of its own. At home, expect 11 kW AC.
