Trip planner
Plan an EV trip around the chargers that exist
Route any US electric car to its next compatible DC fast charger — with the state of charge you arrive and leave on, the minutes each stop takes, and what the public charging adds up to. If your car is not in the catalogue, add it in about a minute.
Trip planner
Where are you going?
Route
Charge
Choose a car and the map fills with every station it can plug into, out of the 6,338 in the directory.
Your route, with the stops it needs
Pick a car and its chargers appear on the map. Then add two places and the drive is drawn with the stops it needs — and the state of charge you arrive and leave on.
How it works
Three decisions, then the plan
The car you actually drive
Pick one of 105 models from the catalogue, each with its EPA range, usable battery and real DC inlets. Not listed? Add it with ChatGPT or by hand — the planner treats your car with the same maths, and keeps it in your browser.
A road, not a radius
The route is a real driving line, and a charger counts only if it is within 5 miles of it and has the plug your car takes. No adapters are assumed. The planner prefers the furthest charger it can reach that delivers 150 kW or more, so it stops late and briefly instead of often and slowly.
The charge, not just the pins
Every stop shows the state of charge on arrival and departure, the minutes plugged in from a taper model capped by the station's power, and the cost at that station's own per-kWh tariff. The total includes the detour miles and the time they take.
What the numbers assume
Estimates you can audit
A trip plan is a model, and a model is only as honest as its assumptions. These are all of them; the page applies the same rules to every car in the catalogue.
- RangeEPA combined, scaled by the route's average speed, then by 0.78 in winter mode.
- ReserveThe planner will not plan to sit below 10% between stops, or below the arrival charge you choose at the destination.
- Charging timeAbout 85% of the lower of the car's and the station's peak below 50%, 55% to 80%, 30% above, plus two minutes per stop.
- CostThe station's published per-kWh tariff where it has one, otherwise the national median of $0.35.
- AvailabilityNot tracked. A planned stop is a charger with a published spec, not a reserved stall — check the network's app before relying on one.
- CoverageThe directory holds 6,338 stations in 23 states, of which 749 are DC fast. A drive is plannable only where a compatible fast charger exists; when the plan runs out, it says how many miles it got and what is missing.
Questions
Before you trust a stop
Can I plan a trip for a car that isn't in the catalogue?
Yes. Choose “My car isn't listed” in the vehicle picker, then either hand a prefilled prompt to ChatGPT and paste its JSON reply back, or type the range, battery and connectors yourself. Both are validated the same way and saved in your browser, so the plan can use a car the 105-model catalogue has never seen. Nothing is uploaded.
How does the planner choose where to stop?
It matches the drive against 749 DC fast stations that sit within 5 miles of the road and accept the car's own plug — CCS1, NACS or CHAdeMO, with no adapters assumed. It drives the battery forward along the route, keeps a 10% reserve, and prefers the furthest charger it can reach that can deliver at least 150 kW, so a stop is as late and as short as the car allows.
How accurate are the range and charging estimates?
Range starts from the car's EPA combined figure, is scaled by the route's average speed, and drops 22% in winter mode. Charging time prices each stop with a taper — close to peak below 50%, slower to 80%, slowest above it — capped by the station's listed power. They are planning estimates, not a guarantee: wind, load, temperature and a charger's actual output all move the result.
Does it work in winter?
Switch the season to Winter and the plan assumes 22% less range before it picks any stop. That is the conservative middle of published cold-weather comparisons for US highway driving, and it is a flat factor because the planner does not know the forecast along the route. It typically adds one stop to a long drive; it never leaves you planning to arrive on fumes.
Is the trip planner free, and do I need an account?
Free, with no account. The page is static and every calculation runs in your browser. The only requests it makes are an address search and a driving route to OpenStreetMap's public services; the 6,338-station catalog is fetched once and reused. Your car and your trip stay on your device unless you copy a share link.
Does the planner know whether a charger is free right now?
No. EVDIR does not track live stall availability. The plan uses the station's listed power, connectors and per-kWh tariff, so treat the stop as a good charger with a published spec rather than a reserved stall. Check the network's own app before relying on one at 2 a.m.
