Static load/charge management
Static load/charge management can be implemented only with an EV charg-
ing box from the VALUE or ADVANCED product lines as the control box.
EV charging boxes from the VALUE and ADVANCED product lines can be
connected as satellite boxes.
With static load/charge management, the total current for up to 16 networked
chargingpointscanbedened(globalcurrentlimit).Themaximumtotal
current is determined based on the available connected power of the domes-
tic installation or sub-distribution, minus the maximum power required by all
other devices in the same distribution circuit.

to all active charging points in the charging network. Whenever a vehicle in
the network is registered or deregistered for charging, the distribution of the
total current is adjusted accordingly.

Dynamic load/charge management
Dynamic load/charge management can be implemented only with an EV
charging box from the ADVANCED product line as control box. EV charging
boxes from the VALUE and ADVANCED product lines can be connected as
satellite boxes. An energy meter must be available in a domestic installation.
The energy meter continuously monitors the total current which the EV
charging boxes and other electrical devices in the building require, and
continuously calculates the total current that is available for charging.
The power measurement integrated in every EV charging box records the
vehicle-specicchargingcurrentandreportsthistothecontrolbox,which
distributes the available total current accordingly.
The total current is distributed across all active charging points: when the
other electrical devices require less energy, there is more current available for
charging. When the other electrical devices require more power, the charging
current is reduced.
External load/charge management
All EV charging boxes must be connected in a network with an external
controller for external load/charge management.

actual charged power to the controller.
