About EVRange
EVRange was created to solve one of the biggest pain points for electric vehicle drivers: understanding how far you can actually drive in real-world conditions. We believe that accurate range information empowers drivers to make confident decisions—whether you're planning a road trip, evaluating an EV purchase, or simply trying to understand your daily commute capabilities.
Our Mission
EVRange was created to solve one of the biggest pain points for electric vehicle drivers: understanding how far you can actually drive in real-world conditions. We believe that accurate range information empowers drivers to make confident decisions—whether you're planning a road trip, evaluating an EV purchase, or simply trying to understand your daily commute capabilities.
Who We Are
EVRange is built and maintained by Omar Jlab, an EV owner and independent researcher. After years of watching real-world range fall short of the optimistic figures on manufacturer brochures, he created EVRange to give drivers honest, condition-adjusted estimates. Every model page and article is researched and reviewed personally — cross-checking official WLTP and EPA ratings against published real-world testing before it goes live.
How Our Calculator Works
WLTP/EPA Baseline Data
We collect official range ratings from manufacturer specifications, WLTP (Worldwide Harmonised Light Vehicles Test Procedure) certifications, and EPA testing when available. These serve as our baseline figures.
Scientific Correction Factors
We apply peer-reviewed correction factors from studies by organizations like AAA, Norwegian Automobile Federation (NAF), ADAC, and independent researchers. These factors account for temperature impact on battery chemistry, aerodynamic drag at different speeds, HVAC energy consumption, regenerative braking efficiency, and rolling resistance variations.
Personalized Calculation
Your inputs (temperature, speed, driving style, terrain, heating/cooling usage) are combined using weighted algorithms that reflect real-world energy consumption patterns. The result is an estimate tailored to your specific driving scenario.
Our Data Sources
Transparency is important to us. Here's where our data comes from:
Our Methodology
Our range calculation model incorporates the following scientific principles:
Temperature Impact
Based on studies showing lithium-ion batteries lose 10-40% capacity in cold conditions. We use temperature coefficients derived from AAA's 2019 cold weather study and NAF's winter range tests.
Speed & Aerodynamics
Air resistance increases with the square of velocity. Using each vehicle's drag coefficient (Cd) and frontal area, we calculate energy consumption at different speeds.
HVAC Consumption
Heating a cabin without engine waste heat requires significant battery power. Heat pumps reduce this impact by 40-60% compared to resistive heating. We model both scenarios.
Driving Style
Aggressive acceleration and hard braking reduce efficiency by 15-25% compared to smooth, eco-conscious driving. Regenerative braking recovery varies by system and driving patterns.
Accuracy & Limitations
Our estimates are designed to give you a realistic picture of achievable range, but they are not guarantees. Real-world range can vary significantly based on factors we cannot model, including:
Always plan trips with a safety margin, especially in cold weather or on unfamiliar routes. Use manufacturer navigation and charging planning tools for critical journeys.
