CC612 charge controller
• If a malfunction occurs, a report is sent to the backend system using the OCPP protocol.
• Data management and control functionality of the charge controller:
– Termination of the charging process after tripping of the residual current device (RCD) due to a
residual current.
– Detection of critical fault currents by the RCM sensor. For the vehicle owner, this can be an early-
warning, provided that the charge controller is connected to an energy management system
and that it supports this function.
– Load current and cooling control (via a temperature sensor)
The charge controller has internal temperature sensors (on the inside of the controller housing)
that allow the temperature in the ambient environment of the charge controller to be estima-
ted. Based on this estimation it is possible to dynamically reduce the charging current or even
suspend charging. This feature can serve to maintain an ambient temperature within the per-
missible range of the components used in a charging system. Two temperature thresholds can
be set on the manufacturer configuration tab and are based on measurements in common hou-
sing scenarios. The first threshold reduces the charging current to the configured value if it is ex-
ceeded. The second threshold will suspend charging.

The temperature measurement is an estimation based on temperature sensors positioned on the inside of
the controller housing where the actual temperature is affected by heat generated by the controller itself.
Because the threshold values are based on measurements in common housing scenarios, each charging
system vendor should undertake practical measurement experiments to validate the correctness of these
thresholds and add offsets if necessary.
• Dynamic load management (DLM):
The charge controller comes with a DLM software, which is fully usable independent of a backend
connection. It detects which charging current is applied to which phase and thus avoids the occur-
rence of peak loads and unbalanced loads. Maximum number of charging points in a network: 250.
• Remote:
– Software updates
– Temperature and residual current monitoring
– Remote login allows for remote maintenance options that reduce the number of maintenance
personal deployments per charger
– Load management through Modbus TCP, SMA SEMP, EEBUS, ASKI

Risk of damage when pulling out the measuring current
transformer plug!
If the measuring current transformer plug is pulled out
using too much force, the enclosure and the internal components may be
damaged. Use needle-nose pliers to unlock the measuring current transfor-
mer plug.
