10.3 HLC 15118 (ISO 15118)
The Webasto Live supports charging in accordance with ISO 15118. These parameters are used to configure the implementation of ISO
15118 communication with the vehicle. The parameters required by your vehicle can be found in your vehicle documents.
NOTE
Only a few manufacturers have currently implemented
ISO 15118 in their vehicles. This is a future standard,
which is already supported today by Webasto in the
Webasto Live.
10.4 Dynamic Load Management (DLM) (local dynamic load management)
The Webasto Live can be operated in the local load management 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 config-
ured correctly.
The load management supports different hierarchical levels with definable upper limits. These must be stored in the master charging
station. The levels are shown schematically below.
Mode 1: DLM Master (with internal DLM-Slave)
When this parameter is selected, the Webasto Live, which assumes the master role, takes into account its own charge point within the
load management.
Mode 2: DLM Master (Standalone)
When this parameter is selected, the charge point of the master charging station is not taken into account in the load management. The
maximum available power for charging processes can be provided there.
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 re-
sponsible master by means of the configured DLM network ID.
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 configured
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.
DLM Algorithm – Algorithm for the load management (no selection currently possible)
Select the algorithm here which should be used for distributing the load in the charging cluster. Webasto is working continuously on im-
proving and choosing the load management algorithms which are then made available as future firmware updates.
FIFO – Uniform distribution of the charging power at all charging stations
The available charging power is divided up equally between all charging stations in a load management cluster. If no available power is
present and a new vehicle would like to start a charging process, it must wait until sufficient charging power is available.
DLM Algorithm Sample Rate – Interval between two iterations of the load management algorithm
This parameter is used to adjust the interval in which the master calculates and distributes new default values for the slaves. If a new ve-
hicle 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 meter is used, the meter readings between the iterative steps are averaged.
Default Value: 30
