About FrostRange

FrostRange is an independent data and research publication created to answer one question precisely: how much range does an electric vehicle actually lose when temperatures drop below freezing? We publish model-by-model winter performance analyses, climate-specific loss estimates, and practical battery preconditioning tactics across cold-climate regions in the United States, Canada, and Northern Europe.

Editorial Independence & Standards

FrostRange operates with strict editorial independence. We are not owned by, affiliated with, or sponsored by any automotive manufacturer, charging network operator, or energy utility. Our analyses, rankings, and commentary are conducted solely to provide transparent, honest, and technically grounded advice to EV drivers and prospective buyers.

When products such as Level 2 home chargers or winter accessories are mentioned, editorial recommendations are made on technical merits (e.g., NEMA 4 cold-weather cable ratings, UL certifications, and thermal performance). While some links are affiliate links, commercial relationships never dictate rankings or estimates.

Who's Behind This Project

Félix Delgado founded FrostRange out of frustration with the gap between EPA lab test numbers and real winter road conditions. With a technical background in software and systems modeling, he spent months analyzing telemetry from cold-climate EV owners, standardized testing cycles, and public fleet datasets to develop a transparent, reproducible loss-band estimation framework.

Data Sourcing & Verification

Every benchmark and data point on FrostRange is anchored in verified public research:

  • Official baseline ratings: Verified against the US Department of Energy / EPA FuelEconomy.gov database and European WLTP manufacturer filings at 20°C (68°F).
  • Empirical fleet telemetry: Sourced from Recurrent Auto's multi-year telemetry studies across tens of thousands of connected vehicles in freezing conditions.
  • Controlled laboratory benchmarks: Grounded in the American Automobile Association (AAA) cold-weather dynamometer tests at -7°C (20°F).
  • Real-world extreme tests: Cross-referenced with the Norwegian Automobile Federation (NAF) 'El Prix' annual winter range and cold-charging tests in sub-zero Nordic conditions.

Commitment to Accuracy & Corrections

We clearly distinguish between measured laboratory facts and modeled temperature estimates. Automotive technology evolves rapidly: heat pump configurations, battery chemistries (LFP vs. NCM), and BMS firmware updates change vehicle performance over time.

If you identify outdated vehicle specifications, trim discrepancies, or have empirical fleet data to contribute, our editorial team welcomes corrections and feedback at frostrange@proton.me. We review submissions promptly and log all substantive updates in our changelog.
