4 Functions
The following chapters describe special functions of the charging station.
4.1 Load management in the local charging network
Load management in a local charging network allows multiple KeContact
charging stations to operate on a common supply. The maximum power al-
lowed by the supply line is divided by the master charging station.
4.1.1 Equal allocation mode
If the parallel active charging stations in a local charging network request
more power than the power supply provides (set maximum current), the
available charging current is divided evenly across all charging sessions.
Charging current per charging station = set maximum current per
phase / number of active charging sessions on this phase
If insufficient power is available for an additional charging process in the
charging network (set minimum current is underrun), the new charging
process will be queued. Every 15 minutes, an active charging session is
paused in sequence, queued to the back of the queue, and the next charge
session in the queue continues.
4.1.2 Current limiting
The current limiting for the charging station can be regulated in various
ways.
● Setting by means of DIP switches locally on each charging station
● Specification by master charging station
● Specification via UDP connection
● Reading out an external meter using Modbus TCP
If a current limit is specified via several different types, then the lowest preset
value is used for the currently valid current limit.
4.2 RFID authorization
Certain device variants are equipped with an RFID reader, which enables
the authorization of a charging process with RFID cards in accordance with
ISO 14443 and ISO 15693. The RFID authorization only allows a charging
session to be started if an identification takes place by means of an RFID
card.
The following chapters will first explain the displays and signals and then de-
scribe the procedure for authorization using RFID.
