About EVStrada

EVStrada answers one specific question: if I drive from A to B in this electric vehicle, with this many passengers and this much luggage, in this season — how much energy will I actually consume, and is my battery sufficient?

What we are (and what we aren't)

EVStrada is a pre-trip decision tool. It is not a navigation app, not a real-time router, and not a replacement for Google Maps or A Better Routeplanner. Use it before you leave to understand the energy demand of a trip — then plan accordingly.

Core principles

  • Ranges, not single numbers. Real-world consumption depends on driving style, weather, and dozens of variables we can't measure. We show optimistic, realistic, and conservative estimates so you can plan for the worst case.
  • No black boxes. Every number on the results page is broken down: how much from terrain, weight, temperature, and what regen recovers. See methodology for the underlying formulas.
  • Free, open data. Route geometry comes from OpenRouteService (SRTM 90 m elevation), weather from Open-Meteo, vehicle specs from manufacturer WLTP figures.

Caveats

Charging stops, highway speed limits, and headwinds are not yet modeled. The current formula uses one average speed per trip rather than per-segment speed. We'll iterate on these in future versions.

Data sources

EVStrada combines several open datasets. Where it matters for accuracy or attribution, we name the upstream:

  • Routing & elevation: OpenRouteService (Pelias geocoding + SRTM 90 m elevation DEM)
  • Weather: Open-Meteo historical climate archive — 3-year mean by season, blended along the route
  • Vehicle catalog: OpenEV (manufacturer WLTP figures, calibrated against EV-Database community averages)
  • Map tiles & place names: OpenStreetMap contributors (ODbL)
  • Charging stations: Open Charge Map (CC BY-SA 4.0)

The exact multiplier tables — terrain, temperature, speed, weight, drag — are public at /formulas. The plain-language walkthrough lives at /methodology.

Who maintains EVStrada

EVStrada is an independent open project — no parent company, no investor, no affiliate scheme. Code, formulas, and the vehicle catalog live in a public repository at github.com/hhvardanai/evmeter. Issues, corrections, and pull requests are welcome.

For data corrections, missing vehicles, or general questions, the fastest channel is opening an issue on the repo. For private contact (e.g. press, partnerships), email [email protected].

How to cite EVStrada

If you want to reference an EVStrada estimate in a blog post, video, or academic paper, please link the specific result page (any /trip/<slug> URL is permanent and indexable) rather than the calculator homepage. The result page carries the exact inputs the estimate was made under so the citation is reproducible.
