ChargePath was created because the tools available to electric vehicle drivers were either too generic or locked behind subscriptions. We build precise, free calculators that run in your browser — no account, no data collection, no guesswork.
The gap between the EPA range figure on a window sticker and what a driver actually experiences on a cold January highway is not a bug. It is physics. Temperature, speed, load, and battery age all reduce range from the advertised number — sometimes by 30% or more.
ChargePath builds tools that account for those variables. Our EV Range Calculator adjusts for temperature conditions, driving speed, and reserve buffers. Our Charging Cost Estimator breaks down the actual annual cost of home charging versus public stations. Our blog covers the mechanics behind battery degradation, charging infrastructure decisions, and long-trip planning — written by people who work in the field.
We do not sell subscriptions, collect your data, or display advertising. The tools run entirely in your browser. We maintain the site because we believe EV ownership should be less opaque, not more.
Generic answers are not useful when you are planning a 340-mile drive with two children and a dog. Every calculation accounts for the variables that matter.
No freemium tiers, no paywalled results, no email-gate. Tools on ChargePath are free because restricting access to accurate information does not serve drivers.
No account creation, no tracking of individual calculations, no sale of usage data. What you calculate stays in your browser session and nowhere else.
Our adjustment factors and content are based on published research and real-world fleet data, not marketing estimates or manufacturer claims.
Marcus spent 9 years managing electric fleet transitions for logistics operators. He built ChargePath's range model from field data collected across 2.4 million annual fleet miles.
Dr. Holt contributes battery chemistry expertise to ChargePath's content and tool calibration. Her research background spans 17 published studies on lithium-ion degradation.
James designs EV drivetrain systems and contributes the engineering perspective to ChargePath's tools. He has worked with OEMs across North America and Germany for over a decade.
