Show HN: EV range calculator – range circles and charger map (700 models)
2 コメント
Neat project! For anyone building or testing EV fleet management software who needs realistic vehicle movement data, Moveet (https://github.com/ivannovazzi/moveet) might be useful — it's an open-source simulator that drives synthetic vehicles along real OSM road networks using A* pathfinding, streaming GPS positions over WebSocket. It supports Kafka and REST sinks so you can feed position data straight into whatever backend you're testing.
Does it consider the case when the roads are not straigh?
You pick your car, drop a start pin, set your current charge %, and hit Compute Reach. You get two circles — outer for one-way range, inner for round-trip — plus all charging stations within reach as pins. Click any pin to open navigation in Google Maps.
Stack: vanilla JS + Leaflet, no build step, hosted on Vercel. Charger data merges OpenChargeMap and OpenStreetMap Overpass with deduplication. 700+ EV presets across 20+ markets (US, EU, India, China, AU, etc.) synced every 12h via a Python pipeline on GitHub Actions.
The catalog pipeline ingests fueleconomy.gov, afdc.energy.gov, cardekho.com, and greenvehicleguide.gov.au, plus region-native seed files. It has anti-regression guardrails and a canary→stable promotion workflow so bad syncs don't silently ship.

Feedback welcome — especially on range accuracy and charger pin coverage in non-US markets.
