Load BalancingEnable Load Balancing
Max. Total PowerDetermines the maximum available house connection power. This line is available to the house, incl. all consumers and charging stations
Power ReserveSince fluctuations due to short-term power peaks can always occur during the regulation of the power, you should specify a reserve in the field "Power Reserve" which is attracted by the house connection power and is never touched. During regulation, the Charging Manager checks whether there is nevertheless an overdrawing of the available house connection power The reserve should be chosen higher, the less information is available about the usage of each phase (by suitable meters).
OverdraftIn the field "Overdraft" the Charging Manager enters this value of the overdraft in watts that exceeds the reserve. This allows you to see later how well the regulation is working and whether you should set more power reserve.
Overdraft should ideally be 0 and remain so
Max. Total EVSE PowerDepending on the house installation, it may be that an additional power line has been laid for the charging stations exclusively for charging electric cars. "Max. Total EVSE Power" determines the maximum power of this line
OCPP server TLSActivate, deactivate or auto-detect TLS
OCPP server portTCP/IP port of the OCPP server in the cFos Charging Manager
OCPP server passwordPassword for logging into the OCPP server
On Device disableThe "On device deactivation" checkbox tells the Charging Manager what should happen if a charging station is deactivated in the configuration menu. You can choose whether the charging station should then be deactivated (charging is prevented) or whether the charging station should be set to a minimum or maximum power value

Add new devices

Press the button "Add New Meter" to add another intermediate meter. You can set the following values for a meter:

NumberThis is a freely selectable number that is displayed in the overview, e.g. the number of the parking space whose consumption is to be measured
NameHere you can give the intermediate meter a name
DescriptionHere you can add a small description
Device typeWith this select box you choose which device it is. The Charging Manager supports a number of different devices. We will expand the list of supported devices over time. Among the supported devices is an S0 intermediate meter, which you can connect to one of the two inputs of the cFos Power Brain controller. There are also other common intermediate meters and virtual meters to choose from. The virtual counters are internal Charging Manager counters that sum up certain power values so that they can be nicely displayed in the overview. There is also a simulated counter for experimentation. For the counter you have to set the following:
addressWith the destination address you tell the Charging Manager how to address the device. You can either specify an IP address:port or specify a COM port and then the COM parameters, e.g. COM1,9600,8,n,1
IDIf the device is a Modbus device, you must enter the Modbus Slave ID of the device here
enabledThe checkbox decides whether the device is enabled (i.e. the Charging Manager controls it or reads it out) or whether it should only be stored for later use
RoleThis select box decides which role the meter has. "Display" means that the meter is for display purposes only and is not included in performance calculations. "Consumption" means that the meter measures the power of a consumer. This is subtracted from the set house connection power. With "Production" you set up meters that measure produced power (e.g. from a solar system). This power is added to the existing house connection power and is available to the EVSEs as charging power. Instead of individual generation and consumption meters, you can also install a central meter for your house connection. In this case, set "Role" to "Grid demand". The Charging Manager will then ensure that the total consumption does not exceed that of your house connection. In this case, you should not define any consumption or production counters. You can set up exactly one total counter. Meters with "Role" "Vehicle Consumption" are currently not used directly s. but "Attach"
InvertAllows the counters to be inverted, i.e. the sign of the current power is reversed (if you have installed the counter "the wrong way round". The signs of the power values are then also inverted in power calculations.
Note: Both consumption and generation meters normally have positive power values. The role decides whether a value is subtracted from or added to the house connection power. In the case of the total meter, a positive power reading means consumption, a negative one means feed-in
PhasesThe phases that the meter uses, or 'automatically' recognition based on meter values when loading.
AttachIf a wallbox does not have its own meter, you can "attach" a meter to it. The Charging Manager then assigns this meter to the selected wallbox and regards the power and energy data as those of the corresponding wallbox. Only meters with the "Vehicle Consumption" role can be pinned.
Reset deviceThis allows you to restart a unit

Note: By the way, solar inverters also count as meters. These can often output the currently generated power via Modbus TCP, just like a meter.

Press the button "Add New EVSE" to add another charging station. You can set the following values for a charging station:

Device typeUse this select box to select which device it is. The Charging Manager supports a number of different devices. We will expand the list of supported devices over time. Among the supported devices is the cFos Power Brain wallbox. You will also find other common EVSEs and a simulation for experiments. For the EVSE you have to set the following:
AddressWith the destination address you tell the Charging Manager how to address the device. You can either specify an IP address:port or specify a COM port and then the COM parameters, e.g. COM1,9600,8,n,1
IDIf the device is a Modbus device, you must enter the Modbus Slave ID of the device here. For OCPP devices, enter the Charge Point ID here
ParametersHere you specify parameters to address devices with different start addresses or additional meters
For certain devices, there are parameters that you should be aware of: List of parameters
enabledThe checkbox decides whether the device is enabled (i.e. the Charging Manager controls it or reads it out) or whether it should only be stored for later use
LabelA freely selectable label that appears in the overview when a vehicle is plugged in
Maximum powerThe maximum charging power that this wallbox supports. This can be lower, depending on whether a less powerful cable is connected
PriorityPriority when charging. Default is 0
Phase rotationThe Charging Manager can detect phase imbalances (provided the EVSEs have appropriate meters or meters are connected that can output the current of the individual phases). If the asymmetry is greater than 4.5kW, the Charging Manager lowers the charging current of this charging station or temporarily switches off charging until the symmetry is restored. If you want to charge several vehicles at different EVSEs, the phase position should be reversed during installation, in contrast to other EVSEs. You can set this phase rotation here.
Recommendation: Make it uniform, e.g. 1st EVSE 0 degrees, 2nd EVSE 120 degrees, 3rd EVSE 240 degrees, 4th EVSE again 0 degrees, etc.
Note: The phase rotation refers to the phase difference between the EVSE and the main building phases. The meter and EVSE must always have the same phase rotation. This should always be the case with meters built into EVSEs, while you should pay attention to it when installing external meters. The display of the phases in the selection box in the web interface tells you which phases of the building installation the 3 phases of the EVSE refer to, e.g. at 120 degrees, L2, L3, L1 are the EVSE phases L1, L2, L3 with the building Phases L2, L3, L1 connected. For example, if a car is charging to phase L1 and the EVSE is connected with a phase rotation of 120 degrees, phase L2 in the building is loaded and displayed in the web interface.
PhasesThe phases that the EVSE uses, or 'automatically' recognition based on counter values when charging.
Min. Charging currentThe minimum current for charging, min.6A. Some cars need more to start charging, e.g. Zoe 8A, Landrover possibly 9A.
