EV charging

This page explains the EV layer: what it shows, what a charger's popup holds, and how charging stations along a route work. The map and route controls themselves are described in The map and Planning a route.

Turning on the EV layer

Pick EV Charging in the fuel selector, under the Electric group. Its code is EV. The map then shows charging stations instead of fuel stations.

An operator can make it the first layer visitors see with PUMPERLY_DEFAULT_FUEL=EV.

What the EV layer shows

Pumperly keeps a type on every station: a fuel station, an EV charger, or both. The EV layer shows every station of the second and third kind inside the visible area.

The fuel layers work differently. They show a station only when it has a price for the chosen fuel. A station marked as both appears on the EV layer, and on each fuel layer it has a price for.

Chargers carry no price. That changes a few things on the map:

On a fuel layer	On the EV layer
Dots are coloured by price	Every dot is grey, and every cluster is orange
The price legend shows in the corner	No legend
The max-price slider shows	No max-price slider

Clustering, country markers and the Stats panel work as on any other layer. The station counts in the country markers and the Stats panel include chargers.

Where charger data comes from

Pumperly uses an official national registry where one exists, and Open Charge Map elsewhere:

Where	Source
Spain	Mapa REVE, the official registry, when PUMPERLY_REVE_API_KEY is set. Open Charge Map otherwise.
Germany	The BNetzA Ladesäulenregister by default. PUMPERLY_DE_EV_SOURCE=ocm switches to Open Charge Map.
Every other covered country	Open Charge Map

Open Charge Map needs PUMPERLY_OCM_API_KEY. Without it, every Open Charge Map scraper skips its run. That includes Spain without a REVE key, and Germany with PUMPERLY_DE_EV_SOURCE=ocm.

PUMPERLY_EV_ENABLED=0 turns off charger scraping altogether. EV charging sources covers each source, its licence and how it is refreshed.

What a charger shows

Click a charger to open its popup. It holds:

1. The brand. For chargers this is the operator, when the source names one.
2. The address and the city.
3. The charger's highest power in kW, such as 150 kW, labelled "Max. charging power · No price for EV Charging". When the source lists no power, it reads "Power unknown" instead. The German registry, OpenChargeMap and Mapa REVE all publish power.
4. The same four buttons as any station: Get directions, Show on map, Copy link and Share. See Station popup.

In a route's station list, a charger row shows the operator and the station name. Each source builds that name differently. The German registry, for example, combines the operator with the street and a site label, which tells apart two chargers at one address.

No tariffs, connectors or live availability

Pumperly does not store charging tariffs, connector types or live availability. Its price model holds one price per litre for each fuel. A charging tariff is per kWh and per session, and that does not fit. The popup tells you where a charger is, who runs it and how fast it can charge. Check the operator's app for price and plug type.

Chargers along a route

Route planning on the EV layer works the same way as on a fuel layer. See Planning a route. Pumperly finds the chargers within the search radius of each route and times the detour to each one.

The difference is that no charger has a price. That affects the station list:

Feature	On the EV layer
Search radius, 1 to 25 km	Works as usual
Detour times and the detour basis	Work as usual
Max detour	Works as usual
Sort by Detour or Route km	Works as usual
Sort by Price	Keeps the chargers in route order, since none has a price
Least detour badge	Works as usual
Cheapest and Balanced badges	Never shown
Average price and the difference from it	Not shown

Every charger within the radius is included, because none is left out for lacking a price. A route gets at most 5,000 stations, in route order.

Keep the radius small in cities

Cities have far more chargers than fuel stations. A 5 km radius across a large city can hold hundreds of them. Pumperly times detours in batches of 150 chargers, and each batch is one request. A visitor may send 10 detour requests a minute, so the later batches of a very dense corridor come back as unknown detours. Lower the search radius, or pick a route that avoids the centre. The limits are listed in Limits.

Clicking a charger in the list or on the map adds it to the route as a stop, as on any layer. See Pick a station as a stop.

On the EV layer, the fuel stop planner becomes Plan charging stops. You set the battery size in kWh, the consumption in kWh/100 km, the car's max charge power, and the battery level at the start and at arrival. The planner then picks the chargers along the route that get you there with the least detour and charging time, since chargers have no prices. Each stop charges to at most 80 %, because charging slows sharply above that. Charging time uses the lower of the charger's power and the car's max charge power, capped at 22 kW on AC chargers. On DC it averages 75 % of that, because charging tapers as the battery fills. The reserve defaults to 20 %. Min charger power (Any, 50 kW or 150 kW) skips slower chargers. It also skips chargers whose power is unknown, because the filter can't vouch for them.

Sharing a charger

A charger link must carry fuel=EV. The map only loads chargers on the EV layer, so a link without it opens a fuel layer where the charger never loads. The Copy link and Share buttons add it for you. The EV rule explains it in full.

Summary

• Pick EV Charging (EV) in the fuel selector to see chargers.
• The EV layer shows every charger in view. Chargers have no price, so dots are grey and there is no legend or price slider.
• A charger's popup shows the operator, the address, the city and the highest power in kW. There are no tariffs, connectors or live availability.
• Along a route, detours and the detour filter work as usual. Price sorting and the Cheapest and Balanced badges do not apply.
• Keep the search radius small in cities, or dense corridors run into the detour rate limit.
