Answers to common questions about EV range estimation

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.

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.
