NOTE: The value is case-insensitive.
[General]
scheduler=SIMPLEFEEDBACK
Note: If the value is missing or incorrect, the EQUAL will be used as the default scheduler for the load balancing.
For more information about the schedulers, refer to "The NANOGRID™ schedulers" on page 12.
To do an additional fallback configuration for phase-switching supported stations
If a station is phase-switching it has the capability to either provide 3-phase current or a 1-phase current, on either
phase.
Note: The station node will inform the controller if it has phase-switching capabilities. Only the FIFO and
SIMPLEFEEDBACK schedulers support phase-switching station nodes.
Do an additional fallback configuration in the nanogrid.ini file.
1.
Example:
[STATIC-1]
type=station
parent=MAINPANEL
outlet/size=2
outlet/1/fallback_current=8
outlet/2/fallback_current=8
PhaseRotation=RTS
[SWITCHING-A]
type=station
parent=MAINPANEL
outlet/size=2
outlet/1/fallback_current=8
outlet/1/fallback_output=2
outlet/2/fallback_current=8
outlet/2/fallback_output=3
PhaseRotation=TRS
Note: STATIC-1 is a "normal" non-phase-switching station node. The outlet/x/fallback_output parameter configures
a phase-switching station to set which output must be provided if it goes offline. This parameter is only used for a
phase-switching station and will be ignored for other charging stations.
2.
Use one of the values that follow:
•
0: No output (charging is not allowed).
•
1: 3-phase output.
•
2: 1-phase L1.
•
3: 1-phase L2.
•
4: 1-phase L3.
Feedback from non-EVSE loads
If a node has an external load that is measured by an energy meter, the scheduler takes it into consideration.
8
For example, if a fuse both has a charging station and large fan attached, the load of the fan is measured and the
scheduler takes it into consideration when it controls the charging station.
Example:
[SHARED-BOARD]
type=measuredfuse
meter="modbus/1/1"
rating=20
parent=MAINPANEL
[STATION-1]
type=station
parent=SHARED-BOARD
outlet/size=2
outlet/1/fallback_current=8
outlet/2/fallback_current=8
PhaseRotation=RTS
The meter="modbus/1/1" parameter value is used by the controller to communicate with the energy meter:
Definitions:
modbus
The controller must use the modbus communication protocol to read values from the energy
meter.
1
The energy meter communication wire is connected to the first serial port of the controller.
1
The modbus device address of the energy meter, in this example 1. The address is configured on
the energy meter.
NOTE: For CHARGESTORM CONNECTED 2 stations, modbus/2/1 and modbus/2/2 are reserved for the EVSE EV
feedback modbus energy meters that are located inside the station. This applies if you use a NANOGRID™ local master
controller.
NOTE: Modbus TCP energy meters are also supported. Currently we support Carlo Gavazzi EM24 series.
NOTE: Port 1 is the only available port on the CGC500
Example:
meter=modbus/192.168.0.123 to add a meter which has IP-address 192.168.0.123
Distribution board that measures the whole load
If a node has an energy meter attached that measures the load at the point, for example the aggregated load of the sub
nodes, the scheduler can use that information to make its scheduling.
This contrasts with the measured fuse where only the external load is measured. The aggregated fuse is the sum of
non-EV loads and EV loads.
Example:
[SHARED-BOARD]
type=aggregatedfuse
meter="modbus/1/1"
rating=20
parent=MAINPANEL
