Typical applications are load management and monitoring of charging stations. Load management allows you
to control the power that the vehicle draws before and during a charging process. Further information on
ModBus TCP support can be found on the Internet at www.EM2GO.de.
6.4. RFID cards
The EV Wallbox has an integrated RFID card reader that can read 13.56 MHz cards. The ISO/IEC 14443 A/B,
FeliCa and NFCIP-1 standards are supported, which means that all common RFID and NFC cards and tags
are supported.
The charging station comes with three RFID cards that can be used for offline operation, to start and stop the
charging process, or for online operation in combination with an OCPP backend. Additional RFID cards for
online operation with an OCPP backend are available as an option and have a printed identification number
that must be registered in the OCPP backend.
6.4.1. Authenticating charging processes
To authenticate charging processes, the card is held in front of the Wallbox card reader.
When a card is held up, it is read. The display shows whether the authentication was successful or failed (see
Figs. 6-5 and 6-6).
Fig. 6-5 Authentication successful
It is possible to hold a card in front of the card reader before connecting a vehicle to the charging station. If
authentication is successful, the user is instructed to connect a vehicle.
6.4.2. Programming RFID cards
Before RFID cards can be used for charging, they must be programmed.
RFID cards can be programmed into the charging station in various ways.
