Where do the operator rates come from?

From a curated set of operator price lists, each plan stored with its source and the date it was last verified — both shown in the assumptions section under the ranking. This is a different source from the map and the price comparison, which show rate ranges from the EIPA register. That register carries no session fees, so a full session cost cannot be built from it.

Why does the same operator rank differently for different cars?

Because a per-minute tariff bills time, not energy. A car that accepts power more slowly spends more minutes on the same session and pays more — for an identical number of kWh. The calculator takes those minutes from the chosen model's own power curve, capped at the post you pick.

What does an unknown fee in the table mean?

That the operator does not publish it. The total is then built from what is known, and the missing component is named outright. We do not treat missing information as zero: a total built that way would look precise and be wrong, and it would favour exactly the operators with the least transparent price lists.

Where to charge cheapest

Start of charge (%)

The state of charge you start the session from.

End of charge (%)

The state of charge you end the session at.

Charging post power

Custom station power (kW)

Enter the station's real rating if it differs from the values above. On a per-minute tariff it is what decides the cost of the session.

The ranking compares DC fast-charging tariffs — the session is integrated over the chosen car's DC power curve. It covers operators whose price list we have verified together with its fees. A fee an operator does not publish is marked unknown and left out of the total — it is never counted as zero. Idle fees are stated but never added, because they depend on how long you leave the car once charging has finished.

Subscription plans are compared separately in the: charging-subscription calculator
