What Fluxtrio estimates

Fluxtrio estimates real-world EV range by combining the official standard (WLTP/EPA) with practical factors like outdoor temperature, driving scenario (city/highway/mixed), and battery condition (SoH and usable SOC window). It's designed for quick comparisons and trip sanity checks—without requiring an account.

  • Compare City vs Highway vs Mixed range in one view
  • See how temperature shifts consumption and range
  • Adjust for battery condition (SoH) and usable energy
  • Switch standards (WLTP/EPA) to match your region
  • Share a configuration and results with one click
  • Optional uncertainty view to reflect real-world variability

How to use

  1. Select your vehicle (manufacturer, model, year, variant).
  2. Choose a standard (WLTP/EPA) and a driving scenario (City/Highway/Mixed).
  3. Set outdoor temperature (winter to summer extremes).
  4. Fine-tune Advanced settings (SoH, SOC window, occupancy, driving style) if needed.
  5. Use the results table to compare scenarios and decide what's realistic.

Mini example: Planning a motorway trip at −5°C? Load the "Motorway cruise (cold winter)" preset, then adjust SoH to match your battery, and use the Highway row as your baseline.

Key factors that change EV range

🚗

Speed

Aerodynamic drag grows fast; motorway speeds can cut range significantly.

🌡️

Temperature

Cold increases heating demand and reduces battery efficiency; hot weather can add AC load.

🌧️

Wind & rain/snow

Headwind and wet roads increase consumption.

⛰️

Elevation

Long climbs cost energy; descents recover only part via regen.

🛞

Tires & wheels

Wider tires / bigger wheels often increase rolling resistance.

📦

Payload

More weight means more energy—especially in stop-and-go driving.

❄️

HVAC & preconditioning

Cabin heating/AC and battery heating can be a major variable.

🎯

Driving style

Smooth acceleration and steady speeds usually win.

How the model works

Fluxtrio starts from a baseline efficiency derived from the selected standard (WLTP/EPA) and vehicle configuration. It then applies scenario-based adjustments (City/Highway/Mixed) and temperature-dependent corrections to estimate consumption.

Usable energy is estimated from usable capacity × SoH × usable SOC window. Estimated range is then computed from usable energy / estimated consumption, presented as City/Highway/Combined to help you pick a realistic scenario.

Limitations:

  • Results are an estimate—real range varies with wind, rain/snow, traffic, tire pressure, road surface, and HVAC behavior.
  • Roof boxes, winter tires, and aggressive acceleration can change outcomes dramatically.
  • Use this tool for planning and comparison, not as a guaranteed value.

Frequently Asked Questions

Aerodynamic drag increases quadratically with speed. At motorway speeds (110–130 km/h), the vehicle consumes significantly more energy than at city speeds, leading to substantially lower range.

EPA is generally considered more accurate for real-world conditions because it includes city, highway, and combined cycles. WLTP is the European standard, which can be more optimistic. For the best estimate, use the standard that matches your region.

SoH (State of Health) represents battery health as a percentage of original capacity. For a new vehicle, use 95–100%. For a 2–4 year old vehicle, use 90–95%. For older vehicles, SoH may be lower; check vehicle diagnostics if available.

The usable SOC window is the battery charge range you actually use (e.g., from 90% to 10%). Some vehicles have larger “buffer zones” at the top or bottom, reducing the truly usable capacity. Setting this window helps you estimate available energy more accurately.

Preheating the battery before driving can improve efficiency in cold weather, but it consumes energy. If preheating is done while plugged into a charger, it can help. If done from the vehicle's battery, it may slightly reduce range, but this is often offset by better efficiency during driving.

Winter tires typically have higher rolling resistance than summer tires, which can increase consumption by 5–15%. They may also have different tread patterns that affect aerodynamics. The calculator doesn't account for this directly, but you can use advanced settings for manual adjustment.

For trips with significant elevation changes, use the "Mountain profile" factor in advanced settings or the "Mountains" scenario. Long climbs consume more energy, while descents recover only part through regen. For more accurate estimates, consider breaking the trip into segments with different profiles.

City driving has more stops and starts, meaning more regen and less aerodynamic drag. Highway driving is more affected by aerodynamics and constant speed. In cold weather, heating affects both scenarios, but city driving may have more regen that helps compensate for losses.

Yes! Use the "Share results" button in the header or below the results. It creates a link containing all your settings that you can share with others.

No, Fluxtrio is an independent tool. It is not affiliated with any car brand or manufacturer. We provide unbiased estimates based on publicly available data and standards.

Fluxtrio uses official certified WLTP and EPA values from public sources. Vehicle data is collected from official manufacturer specifications and certification documents. The consumption model is based on physical principles and empirical corrections.

The model is continuously optimized based on user feedback and new data. The vehicle database is regularly updated when new models or specifications become available. The project is currently in pilot operation and actively being developed.
