The charger's data record, as published

The situation

After the portal of stop 05, the compliance manager opens the record itself: what the operator's interface returns for the new charger when the national access point, or any app, asks for it.

The interface speaks OCPI. AFIR does not prescribe the format, but this is how most European operators publish the static and dynamic data the regulation lists.

The questionWhere in the record does each AFIR data item sit, and what in it comes from the ID registration?

Guess firstAFIR names four dynamic data items. Which four fields of the record carry them?RevealHide

status for operational state and availability (two items in one field), tariff_ids pointing to the ad hoc tariff, and energy_mix.is_green_energy for the renewable flag.

What you are looking at

obliges operators to make static and dynamic data on their public charge points available through an application programming interface, free of charge, and to report that interface to the . The regulation lists the data, not the format; in practice the interface speaks , the protocol, whose Locations module describes sites, charge points and connectors and whose Tariffs module carries the prices.

The record below is the new 150 kW charger from stop 02. Select the lines to see which AFIR item each one carries.

One location with one EVSE and one connector. Static data changes when the site changes, dynamic data with every session.

  3. Line 2The ID code, part one

    AFIR asks every Member State to appoint an identification registration organisation that issues ID codes to operators. Country code plus party ID is that code; it opens every record and every EVSE ID of the company.

A composed record in the structure of the OCPI 2.3.0 Location, EVSE, Connector and EnergyMix objects. The data items follow Article 20 of AFIR.

    OCPI marks tariffs for drivers without a contract as AD_HOC_PAYMENT. This is the price AFIR wants shown at the station and in the data, not what any provider charges its own customers.

Tariff type, tax flag, display text and the two price components as OCPI 2.3.0 defines them; the price per kWh and the occupancy fee are what Article 5(4) of AFIR requires at 50 kW and more.

The data items of Article 20 of AFIR against the fields of an OCPI location record.

What the record says about compliance

Three things the compliance manager checks in the raw record, not in a portal: the status timestamp moves when the charger changes state, so the dynamic data is live and not a daily copy; the tariff in the data is the tariff on the screen, because both come from the same object; and the ID code in every identifier is the one the registration organisation issued. A record that passes these three is what AFIR means by data availability. How the same data reaches apps and navigation systems is shown in Charging infrastructure, stop 06.
