Forming charging groups and network topologies
Forming charging groups and network topologies
The Wallbox eM4 Single offers several interfaces for internal communication in a charging group as well as for external communication
with a backend. Here, a distinction is made depending on the wallbox variant:
x
Controller:
The Controller wallbox can be operated either individually or as a charging group together with one or more Extender
wallboxes. Internal communication within the charging group can be set up via WLAN or LAN. For external communication with a
backend, you can use the WLAN or LAN interface or the LTE USB stick and USB filter supplied with the Controller.
x
Extender:
The Extender wallboxes can be operated either individually (stand-alone) or as a charging group together with a
Controller. Internal communication within the charging group can be set up via WLAN or LAN.
ATTENTION
Integration into an existing network infrastructure
If you want to use an existing network infrastructure for communication within a charging group and/or with a backend, you will
need to contact an IT administrator in advance to plan the integration.
The interfaces of the Wallbox eM4 Single can be used to connect a charging group to a backend. The following combinations are
possible:
Controller–backend communication
Controller–Extender communication
WLAN
LAN
LTE
WLAN
LAN
NOTE
Information for network communication
x
The following ports must be available for communication with the Internet (Controller–backend):
HTTP: 80 / HTTPS: 443 / NTP: 123 / OCPP: 7890
x
The following ports must be available for communication within the network (Controller–Extender):
DNS: 53 / mDNS: 5353 / UDP/TCP: 68, 1024, 4332, 5432, 11010
x
The network must assign each wallbox its own IP address (e.g. via DHCP).
The network interfaces are presented below in detail and illustrated with the help of illustrations in practical use. Additional infor-
mation on network communication can be found in the “Network setup for the Wallbox eM4 Twin” instructions via the following link.
