Teaching Additional RFID Cards

The SMA EV Charger Business supports all Mifare variants currently available in the market. SMA Solar Technology AG recommends using cards in the Mifare DESFire series: for example, EV1 or EV3.

Local Whitelist

The Local Whitelist is a backend-independent list that is only saved on the charge controller. The UIDs on the list are always authorized to charge. They do not require a query to the backend.

OCPP Whitelist

The OCPP Whitelist is a local buffer of the backend on the charging point. All the RFIDs from charging card that have been approved by the backend are regularly transferred to the charging point here.

This ensures that a charging process can also be authorized if the charging point has not established a connection to the backend. In addition, this helps to speed up the authorization.

If this option is disabled, a query is always sent to the backend for every query to the charging point (i.e., always when an RFID is presented to the RFID reader). The charging process is not authorized until the query is accepted.

Disable the OCPP Whitelist if you do not have a backend connection.

Requirements:

  • The user interface must be open and you must be logged in.

Procedure:

  1. In the navigation area, select [Authorization].
  2. Under [RFID whitelists] > Enable local whitelist select [On].
  3. If there is a backend connection, under Enable OCPP whitelist select [On].
  4. In the navigation area, select [Whitelists].
  5. Under [Local whitelist] > [Add entry] you can add individual RFID cards.
  6. The [Add entry] window opens.
  7. When the LED of the RFID card reader glows green, hold the RFID card up to the right card reader (card icon) Product Description.
  8. The LED of the RFID card reader glows blue. The RFID card has been imported. In the [Add entry] window, the relevant RFID number has been input.
  9. Select [Add entry] to confirm the RFID number.
  10. Repeat the process for additional RFID cards.
  11. Click on [Save] to save the changes and [Restart].
