6.9.7 Load management in charging point
networks
The tasks described in this section may only
be carried out by a qualified electrician.
From firmware version 1.1 and later, the load man-
agement can be operated in charging point net-
works (up to 100 charging points). Operating prin-
ciple:
n The value of the maximum upper power limit of
the entire charging point network can be con-
figured statistically or dynamically (external en-
ergy meter required).
n The load management distributes the maximum
available power to the connected vehicles. If
less than 6 A is available for the next vehicle,
the last vehicles connected have to wait to start
charging until another vehicle has finished char-
ging.
n The load management provides each vehicle
with as much charging current as the charging
station is configured for.
n A charging station can be configured as load
management master and so takes care of the
load management coordination for all charging
stations in the charging point network. The
charging stations can be added and the load
management configured in the AMTRON® 4In-
stallers app or in the web interface of the load
management master.
n If the downgrade input on the load manage-
ment master is activated, the maximum upper
power limit of the entire charging point network
is reduced to the set value.
Requirement(s):
ü All charging stations that should be operated
with load management should be in the same
network.
1 "6.6 Integrating the product into a local net-
work" [} 23]
n MENNEKES recommends connecting the
products in the network via Ethernet.
n MENNEKES recommends using a router
with an activated DHCP function.
The configuration of the load management in the
entire charging point network can be done via the
AMTRON® 4Installers app or the web interface of a
preferred charging station (load management mas-
ter) in the "Charging point network" menu. All
products that should be taken into consideration by
the load management can be selected or manually
added there. The load management can then be
configured afterwards.
Configuration with a router / switch with a
deactivated DHCP server
If there is no DHCP server active on a router /
switch in the network, or if a static IP address as-
signment needs to be carried out, all charging sta-
tions must be manually assigned their own indi-
vidual static IP address in the same address range.
This must be set individually in the AMTRON® 4In-
stallers app or in the web interface of each char-
ging station.
6.10 Testing the product
The tasks described in this section may only
be carried out by a qualified electrician.
u At initial start-up, test the product in accordance
with IEC 60364-6 and the applicable national
regulations (e.g. in Germany: DIN VDE
0100-600).
The test can be carried out in conjunction with the
MENNEKES test box and standard-compliant test
equipment. The MENNEKES test box simulates
vehicle communication. Test boxes are available as
an accessory from MENNEKES.
