How It Works

Three Steps to Your Range

Enter Your Battery Data

Input your EV's total capacity and current charge state. Default values reflect a typical 75 kWh vehicle at 85% charge.

Set Driving Conditions

Select temperature and speed profile. Cold weather and high speeds significantly reduce real-world range from the EPA estimate.

Get Your Adjusted Range

Receive a projected range accounting for all variables, plus a safe stopping point based on your reserve buffer preference.

Testimonials

What Drivers Say

★★★★★

"I cross 240 miles between cities twice monthly. This tool has been accurate to within 11 miles every single time. I no longer guess at charge stops."

Patricia W. — Tesla Model 3 owner

★★★★★

"The temperature adjustment is what sets this apart. Other calculators ignore cold-weather loss. ChargePath doesn't."

Daniel R. — Rivian R1T owner

★★★★☆

"Used the charging cost estimator to compare home vs. public DCFC for a full year. Saved me from an expensive habit. Clear, honest math."

Naomi K. — Chevrolet Equinox EV owner

FAQ

Frequently Asked Questions

Why does my real range differ from the EPA estimate?

EPA testing uses controlled conditions. Real-world driving involves speed variation, climate control loads, terrain, and temperature — all of which reduce range by 10–30%.

What does the "reserve buffer" setting do?

It calculates the point at which you should stop to charge, preserving a safety margin. A 10% reserve on a 280-mile range means stopping at 252 miles, not waiting for the battery warning.

How accurate are the temperature adjustments?

The factors are based on aggregated real-world data from multiple EV models. Cold weather below 40°F typically reduces range by 12–18%; our default applies a 14% reduction.

Does this work for all EV brands?

Yes. Enter your vehicle's actual battery capacity and your observed efficiency. The calculator is brand-agnostic — it uses your inputs, not manufacturer presets.

What efficiency value should I use?

Check your car's trip computer after several drives. Most EVs average 3.0–4.5 miles/kWh in mixed conditions. The default 3.8 is representative for a mid-size EV at moderate speeds.

Is ChargePath free?
