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.
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.
Aerodynamic drag grows fast; motorway speeds can cut range significantly.
Cold increases heating demand and reduces battery efficiency; hot weather can add AC load.
Headwind and wet roads increase consumption.
Long climbs cost energy; descents recover only part via regen.
Wider tires / bigger wheels often increase rolling resistance.
More weight means more energy—especially in stop-and-go driving.
Cabin heating/AC and battery heating can be a major variable.
Smooth acceleration and steady speeds usually win.
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.
Try these preset scenarios to see how different conditions affect range estimates. Click "Load into calculator" to apply the settings.
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.

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.
Fluxtrio provides an indicative estimate to support planning and comparisons. Always keep a safety margin and follow your vehicle's live consumption and navigation guidance.
