Routing that thinks
like a rider.

Flow finds the roads PEVs can ride, places charge stops at chargers your vehicle can actually use, and avoids freeways by default — not as an option.

The approach

Three problems car routing ignores. Flow solves all three.

Wrong chargers

Car apps route to DC fast-chargers. PEVs can't use those. Flow only shows J1772, RV hookups, and wall outlets — the ones your wheel can actually plug into.

What Flow maps

Wrong roads

Navigation apps take the fastest road — usually a freeway. Flow scores routes by adventure quality, freeway avoidance, and bicycle-network membership first.

The roads it picks

Wrong model

Generic routing ignores terrain. Flow models energy per leg using real elevation gain and loss — a leg that climbs 300m then descends 300m costs more than flat, regardless of net grade.

Explainers

How each piece works.

Chargers you can actually use

Routing · Connector filtering

Connector-authoritative filtering, the co-located J1772 case, multi-source dedup, and why DC fast-chargers are excluded.

Freeways avoided. Good roads found.

Routing · Adventure scoring

Freeway-avoidance policy, the five-factor adventure scorer, bicycle-network candidates, and pre-baked corridor waypoints.
