So berechnen Sie EV Real-World Range
learn.whatIsHeading
The EV Range Calculator estimates how far an electric vehicle can travel on a single charge by factoring in battery capacity, energy efficiency, and real-world conditions like temperature and driving speed.
Formel
- C
- Battery Capacity (kWh) — Total usable energy stored in the battery pack
- E
- Efficiency (mi/kWh) — Distance traveled per kilowatt-hour of energy consumed
- Tf
- Temperature Factor (dimensionless (0-1)) — Multiplier accounting for cold or hot weather energy losses
- SOC
- State of Charge (%) — Current battery charge level as a percentage of total capacity
Schritt-für-Schritt-Anleitung
- 1Enter your EV battery capacity in kilowatt-hours (kWh)
- 2Input your vehicle efficiency rating in miles per kWh (typically 3-4 mi/kWh)
- 3Select the outside temperature to apply a cold/hot weather penalty factor
- 4The calculator multiplies battery capacity by efficiency and adjusts for temperature losses
Gelöste Beispiele
Häufige Fehler vermeiden
- ✕Using EPA-rated range instead of real-world efficiency which is typically 15-25% lower
- ✕Ignoring that highway driving at 70+ mph can reduce range by 20-30% compared to city driving
- ✕Forgetting that cabin heating in winter uses 2-5 kW and significantly reduces range
Häufig gestellte Fragen
How much range do EVs lose in cold weather?
Most EVs lose 20-40% of their rated range at temperatures below 20F (-7C), primarily due to battery chemistry slowdown and cabin heating energy demands.
What is a good efficiency rating for an EV?
Most modern EVs achieve 3.0-4.5 miles per kWh. Smaller, aerodynamic vehicles like the Tesla Model 3 or Hyundai Ioniq 6 tend to be more efficient than larger SUVs and trucks.
Does highway driving reduce EV range?
Yes. Aerodynamic drag increases with the square of speed, so driving at 75 mph can reduce range by 25-30% compared to driving at 55 mph.
