From plug to invoice takes five steps.

This page walks through every step, who sees what along the way, and where the figures for billing come from.

The process

How a charging session runs.

The same path, every day, at every station.

  1. 01

    Connect the station

    Only what you created yourself gets in. Every charging station signs in with an ID and a password of its own, and wrong details already fail during the handshake.

  2. 02

    Present a card

    For the driver it stays one movement of the hand. They hold the card to the reader, and the station asks CPIM.

  3. 03

    CPIM decides

    Nobody waits at the station. The answer arrives within seconds and follows the charging group the card is valid for.

  4. 04

    Record the session

    The price is fixed the moment charging begins and does not move afterwards. Start, end and meter reading together form one charging session.

  5. 05

    Evaluate

    Billing costs no manual work. Consumption is ready by day, week, month and year, and the export opens in Excel.

The setup

Three parts form the chain.
