6.6.4 Subitem „Dynamic Load Management
(DLM)"
The Webasto Live can be operated in the local load manage-
ment both as a master and a slave. Note that there may only be
one DLM master for each load management cluster.
NOTE
Webasto recommends that the DLM only be adjusted
by the installer of the charging station.
NOTE
The load management of the Webasto Live is based on
calculating the charging current and not on the meas-
ured power values. The supply voltage ("Power Source
Voltage") as well as the connected phases ("Phase con-
nected to the Charge Point") and the rotation direction
("Phase rotation of the Charge Point") must be con-
figured correctly.
„Dynamic Load Management - DLM Master / Slave"
The load management supports different hierarchical levels with
definable upper limits. These must be stored in the master char-
ging station. The levels are shown schematically below.
n Mode 1: "DLM Master (with internal DLM-Slave)"
When this parameter is selected, the Webasto Live, which as-
sumes the master role, takes its own charging station into ac-
count within the load management.
n Mode 2: "DLM Master (Standalone)"
When this parameter is selected, the charging station of the
master charging station is not taken into account in the load
management. The maximum available power for charging pro-
cesses can be provided there.
n Mode 3: "DLM Slave (Master-Auto-Discovery)"
Choose this parameter to integrate the Webasto Live as a slave
into a charging cluster. The Webasto Live automatically looks
for the responsible master by means of the configured DLM net-
work ID.
n Mode 4: "DLM Slave (Master-Fixed IP)"
Choose this parameter to operate the Webasto Live as a slave in
a cluster. To detect the correct master its address must be con-
figured in the network.
DLM master settings:
„DLM Network Id"
ID of the charging cluster which administrates the Webasto
Live. Enter the ID of the charging cluster here that the Webasto
Live should administrate as a master. You can enter any number
between 1 and 255. Note that each master charging station
may be assigned to only one single DLM network.
„Disable Discovery Broadcasting"
This parameter deactivates the transmission of DLM discovery
signals in the DLM master. When this parameter is activated,
DLM slaves can no longer automatically find their DLM master
using the DLM Master Auto-Discovery function.
Default value: „Off"
„DLM Algorithm Sample Rate"
This parameter is used to adjust the interval in which the master
calculates and distributes new default values for the slaves.
If a new vehicle starts a charging process during an interval,
then the power available is immediately calculated and returned
as a default value to this vehicle. If an external electricity meter
is used, the readings of the electricity meter are averaged
between the iteration steps.
Default value: 30
„Allow EV Wakeup"
5110490B Configuration Instructions Webasto Live
PWM signal to the electric vehicles that deliberately do not
charge but are "woken up" at a later time for the charging pro-
cess.
Default value: „On"
„EVSE- Sub-Distribution Limit (L1/L2/L3) [A]"
This parameter is used to configure the maximum current in-
tensity for each phase which is provided to the entire charging
cluster. This represents the absolute upper limit of the load
management and must not exceed the values available in the
installation for the common connection point.
NOTE
If multiple charging clusters are used at a common con-
nection point, the total value of all charging clusters
must not exceed the available current intensity.
Default value: 16, 16, 16
„Operator EVSE- Sub-Distribution Limit (L1/L2/L3) [A]"
The parameter configured here must not exceed the values of
the "EVSE Sub-Distribution Limit", and should be below the
"EVSE Sub-Distribution Limit" parameter. This parameter can
also be used to adjust the value actually assigned to the char-
ging cluster during operation.
One OCPP backend can adjust this value dynamically and the
local load management can be integrated into a backend-based
load management. The backend cannot set any parameters that
exceed the "EVSE Sub-Distribution Limit" parameter.
Default value: 16, 16, 16
„External Meter Support"
The Webasto Live supports the integration of an external de-
fault value for the local load management. To do this, connect
the external electricity meter to the master charging station for
load management via the external Modbus connection and con-
figure the external measuring device with the following para-
meters. Ensure correct polarity of the connection:
Parameter
"device ID"
"Baudrate"
"parity"
"stop bit"
"word length"
"Polarity"
"Termination"
Contact the manufacturer of the electricity meter for details on
configuring the parameters of the external measuring device.
Default value: „Off"
NOTE
Use three-phase measuring devices only.
„Meter configuration (Second)"
This parameter is used to configure the model of the external
electricity meter. The Webasto Live supports different types of
external meters. If your available meter type is not listed, then
please consult the manufacturer of the electricity meter.
NOTE
Webasto is constantly checking the functionality of
other electricity meters so that electricity meters that
are not on the list can also be used.
