Functions
The following chapters describe special functions of the charging station.
5.1
Load management in the local charging network
Load management in a local charging network allows multiple charging sta-
tions to operate on a common supply. The maximum power allowed by the
supply line is divided by the master charging station.
Information
A charging process at a client charging station is only possible if there is a
connection to the master charging station. This prevents the connection
from being overloaded.
5.1.1
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.
5.1.2
Unbalanced load compensation
Asymmetrical loads (unbalanced loads) can lead to an unstable network. To
avoid unbalanced loads, a balance is established between the phases of the
charging station during the charging process. The maximum current allowed
for asymmetrical loads can be defined, but is determined by country-specific
requirements.
The unbalanced load compensation can be defined for the entire charging
network or individually for each charging station.
5.1.3
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
●
Assignment by the master
