Luxury EV Charge Planner (100 kWh)
Charge times and range for 100 kWh-class luxury EVs on AC and 250 kW DC — taper-corrected.
Big packs meet big chargers: 100 kWh at 250 kW DC still takes ~22 minutes for a 30→80% leg because of taper. On 11 kW AC, overnight is 9+ hours from empty — which is why luxury EV owners route-plan around DC corridors, not destination charging.
DC charging tapers sharply above 80% SoC — the last 20% can take as long as the previous 50%. Fleet practice: fast-charge to 80% on route, balance to 100% on AC overnight only when the route demands it.
Engineering estimate from published standards and typical equipment data. Site conditions, equipment datasheets and measured data govern the real result — confirm with a qualified engineer.

Frequently asked questions
How long does EV charging really take?+
AC: energy needed ÷ (charger kW × 0.9). DC: the same ÷ (peak kW × ~0.8) because charging tapers above ~60% state of charge. A '30-minute' 30→80% claim becomes 50+ minutes if you push to 95% — the calculator models the taper so plans survive reality.
Why does DC fast charging slow down above 80%?+
Battery protection: as cells fill, the BMS cuts current to prevent lithium plating and heat. The last 20% can take as long as the previous 50%. Road-trip practice: charge 20→80% and drive — chasing 100% at a DC stall wastes both time and stall availability.
What charging speed do I need at home?+
Daily km × Wh/km ÷ overnight hours. A 50 km/day commuter needs barely 1 kW — a regular socket suffices; a 200 km/day fleet car wants 7–11 kW. Oversizing home AC charging is the most common unnecessary EV expense.
How accurate are the range numbers in the Luxury EV Charge Planner (100 kWh)?+
They follow your consumption input — which is the honest variable. Use your car's lifetime average from the trip computer (city ≈ brochure, highway +15–25%, winter +20–30%). With a real Wh/km figure, the range math is exact arithmetic.
