Functions; Load Management In The Local Charging Network - ABB EVLUNIC PRO M Configuration Manual

3.5.4. Import configuration
To load the configuration into another EVLunic Pro M, the USB stick must be plugged in to the desired
charging station. The configuration will be imported automatically and adopted after a restart.

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 EVLunic charging stations to operate on a
common supply. The maximum power allowed by the supply line is divided by the master charging
station.
Information
Charging at a slave charging station is only possible if there is a connection to the master charging
station. This prevents overloading of the connection.
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 lined up. Every 15 minutes, an active
charging session is paused in sequence, lined up at the back of the line, and the next charging session in
the line 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.
