3.2 Product description
The charge controller monitors charging system internal hardware, such as the meter, the
user interface board or the socket. It is characterized by its compact design and size that
in turn enables intelligent, small and cost effective charging systems. Several product va-
riants are available and an overview of these variants is given in Chapter 3.2.1.
To enable the charge controller to communicate, a backend system is required. Given
that most backend providers strictly adhere to the OCPP communication protocol, the
charge controller is OCPP compliant. All specified messages in OCPP are supported as
well as some vendor-specific extensions based on the DataTransfer message. Integration
tests with the backend implementations of providers such as Vattenfall, Bosch, NTT and
DRIIVZ have been successfully carried out. The charge controller can be operated as an
"always on" system that is always connected to a mobile network. The controller supports
4G mobile networks. Connectivity for online operation requires a SIM card (which is not
included in delivery). User interaction is facilitated using an RFID module, which consists
of an RFID card reader and LEDs. Charging is initiated by holding a valid RFID card close
to the reader. In offline operation, the charge controller can optionally allow charging
without authorization or it can authorize users based on RFID and a local white list of
authorized RFID cards.

3.3 Functional description
As well as the charge controller, a charging system also consists of a type A RCD, a relay
contactor, which is directly connected to a type 1 or type 2 socket, or to an attached cable
with a type 1 or type 2 plug. These essential components are shown in Chapter 3.3.2.
3.3.1 General functions
• A charging system may also consist of a meter, and if the meter should be read digi-
tally, either a smart digital meter (EMH eHZ) or a digital Modbus meter is required.
• The charge controller reads the digital eHZ meter readings using a standard opti-
cal reader attached to the charge controller via an RJ10 plug.
• If the Modbus version is used, the Modbus wires are attached directly to the
charge controller.
• Alternatively, any meter with an S0 interface can be attached to one of the availa-
ble inputs.
• A 12 V power supply is needed to operate the charge controller and an RFID module
can be used to facilitate simple user interaction. The RFID module is a separate PCB
and is connected to the charge controller using a standard RJ45 cable.
• Power flow toward the vehicle is controlled by the contactor (using a signal voltage
of up to 30 V), which is itself controlled by the the charge controller via a relay in the
charge controller.
• The SIM card slot (available on charge controller Master variants only) is positioned
on the charge controller front panel. The SIM card can have a PIN number which can
be configured via an internal configuration web interface. The APN settings for the
card can also be configured via an internal configuration web interface.
• Also positioned on the front panel are two USB interfaces:
• The first known as CONFIG is used to configure the charge controller. Optionally,
this interface can also be used to apply software updates.
• The other USB interface allows the connection of peripheral USB devices.
• Both USB interfaces are used to enable a Master/Slave connection. Master/Slave
operation is configured by connecting the USB configuration interface (CONFIG)
of the data gateway with 4G modem to the Ethernet/USB WLAN interface of the
data gateway without 4G modem using a USB cable. Refer to Page 17 for further
information.
• Only the front panel of data gateways with 4G modem variants features a connec-
tion for a 4G antenna.

• For AC charging system fault monitoring, the charge controller features an integra-
ted RDC-MD which uses an externally connected current transformer for fault moni-
toring of AC charging systems. With the integrated DC residual current monitoring
function, only a RCD type A is required in the charging system.
• Data exchange between the EV and the charging system is possible via ISO 15118
compliant Powerline Communication (PLC). This feature is optional and if
purchased, will be enabled by a future software update.
• If a malfunction occurs, a report is sent to the backend system using the OCPP
protocol.
• The data management and control functionality of the charge controller provides:
• Remote restart after a residual current trip that is recognized by the CC612.
• The smart sensor detects critical fault currents before the relays are tripped. This
can be used a prewarning for the vehicle owner.
• Load current and cooling control (via a temperature sensor)
The charge controller has internal temperature sensors (on the inside of the cont-
roller housing) that allow the temperature in the ambient environment of the
charge controller to be estimated. Based on this estimation it is possible to dyna-
mically reduce the charging current or even suspend charging. This feature can
serve to maintain an ambient temperature within the permissible 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 com-
mon housing scenarios. The first threshold reduces the charging current to the
configured value if it is exceeded. The second threshold will suspend charging.
The charge controller with optional RDC-MD only works in combination
with the measuring current transformer (which must be ordered separa-
tely).
The temperature measurement is an estimation based on temperature
sensors positioned on the inside of the controller housing where the actu-
al temperature is affected by heat generated by the controller itself. Be-
cause the threshold values are based on measurements in common
housing scenarios, each charging system vendor should undertake practi-
cal measurement experiments to validate the correctness of these
thresholds and add offsets if necessary.
• Peer group mechanism
With the help of a peer group mechanism, it is possible to assign a current limit to
a set of charge controllers to share. To use this feature, the charge controllers
need to be connected in a way that enables them to establish TCP connections
with each other. This is possible, for example, using a USB to Ethernet adapter or
with a direct USB connection. In the operator web interface for each individual
member of this peer group, the IP addresses of all other peer group members
must be listed in the configuration parameter "Peer Group". In addition, all peer
group members need to have the same "Peer group maximum current (A)" set-
ting. Once configured, the total current is available to one controller if only one
controller is charging. This controller will however not exceed its maximum hard-
ware current setting. As more controllers start charging, the current will be evenly
shared by the peers. As controllers stop charging, the current is evenly distributed
to those that are still charging.
In the event two charge controllers are used in a single charging system and the
charge controllers are connected to a central charging system computer via their
USB device ports, it is necessary to assign individual IP addresses to these control-
lers to enable TCP/IP connectivity between both. This is possible using the confi-
guration parameters "USB additional fixed IP" and "USB additional fixed gateway".
The central charging system computer could either use bridging or routing bet-
ween the USB interface to enable connectivity.
• 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

5.2.1 Master/Slave connections
The charge controller can function as a data gateway with 4G modem (the dedicated con-
troller is switched into Master mode) or data gateway without 4G modem. Master/Slave
operation can be configured by connecting the USB configuration interface of one char-
ge controller (DLM Master) to a USB interface for Ethernet/WLAN of the second charge
controller (DLM Slave) using a USB cable. For each DLM Master/DLM Slave variant, there
are connections common to both (these are described in the following sections) and the-
re are differences, which are described in Chapter 5.2.2.
Currently one DLM Slave can connect to the DLM Master. The communication protocol is
binary OCPP 1.6. Essentially the Master controller becomes the OCPP backend for the
DLM Slave. The DLM Master exposes each DLM Slave as an additional connector to the
backend.
A charge controller is assigned the Master and Slave role on the Manufacturer tab
(see Page 35). Each DLM Slave controller then needs to be assigned the IP address of of
the DLM Master as its binary OCPP hostname and needs to use port 1600 as the binary
OCPP port to connect to the DLM Master. Multiple connectivity technologies to connect
DLM Master and DLM Slave can be used, for example Ethernet and, where available,
WLAN.
The Master is assigned an additional IP address of 192.168.125.124 on the
Settings tab without assigning a standard gateway. The Slave uses the
IP address 192.168.125.125 to connect to the Master. Using USB as the connection
technology is more cost efficient than using multiple Ethernet cables or WLAN, but limits
the distance of the controllers to a few meters as the maximum length of a USB cable is 5
meters. The DLM Slave configuration web page (e.g. http://192.168.123.123) then offers
links to access the Master and the Slave configuration.
5.2.1.1 USB configuration interface (CONFIG)
The USB configuration interface (CONFIG) on the charge controller front panel is con-
nected to a conventional laptop, PC or tablet computer with a normal USB host interface
via a micro USB cable. This interface allows the device to be configured locally. In addi-
tion, it also enables software updates. Configuration details are outlined in Chapter 6.1.1.
In addition, Master/Slave operation can be configured by connecting the USB configura-
tion interface of one charge controller (DLM Master) to a USB interface for Ethernet/
WLAN of the second charge controller (DLM Slave) using a USB cable.
5.2.1.2 USB interface for Ethernet/WLAN adapter
The USB Ethernet/WLAN interface provides a way of connecting the charge controller to
an existing Ethernet/WLAN network. Refer to Chapter 6.6.2.3. In addition, Master/Slave
operation can be configured by connecting the USB configuration interface of one char-
ge controller (DLM Master) to a USB interface for Ethernet/WLAN of the second charge
controller (DLM Slave) using a USB cable.
5.2.1.3 Front panel LEDs (ALARM, READY, PLC)
The LEDs located on the front panel are used to indicate:
• An error has occurred (ALARM)
• Online connectivity to a backend system (READY)
• Optional Powerline Communication (PLC) acc. to ISO 15118
(This LED is not shown on the front panel of variants which do not feature PLC.)
5.2.1.4 12 V power supply
The charge controller is powered by a 12 V primary power supply on terminals 12V and
0V.
5.2.1.5 Contactor connection
The charge controller controls the contactor that in turn controls the power flow toward
the vehicle. Contactor control is exercised by a relay in the charge controller whose
contacts are rated up to 30 V/1 A. The actual power for the signal circuit has to be looped
into the circuit by correct wiring, i.e. one pin of the charge controller relay 1 (11) has to
be connected to the 12 V power supply, the second charge controller relay 1 pin (14)
must be connected to the contactor control pin. The second contactor control pin must
be connected to the other pole (0V) of the power source.
If an intermediate relay is required, then the second charge controller relay 1 pin (14)
must be connected to the intermediate relay control pin instead of to the contactor
control pin. The second intermediate relay control pin must be connected to the other
pole (0 V) of the power source. The contactor control pin is then connected to the supply
voltage (e.g. 230 V) and the other pin is connected to the neutral conductor.
CAUTION
Relay 1 is rated for 30 V/1 A. An intermediate relay may be required if this
rating is considered inadequate.

5.2.1.6 Control Pilot (CP) and Proximity Pilot (PP) connections
The Control Pilot (CP) and Proximity Pilot (PP) contacts connect the charge controller to
the outlet, enabling it to communicate with the vehicle and the cable plug. The CP and
PP contact allow the charge controller to determine whether a cord has been plugged
into the socket (proximity) and to inform the vehicle about the amount of power it can
draw (refer to IEC 61851).
5.2.1.7 I/O extension
The CC612 has additional I/O interfaces available via a configurable 3-channel I/O inter-
face (connector C: 21, 24, IN1-, IN1+, IN2-, IN2+) that can be used for multiple purposes,
for example:
• Parking management interface (The supported communication protocol is proprie-
tary to Scheidt & Bachmann and based on the available auxiliary relay and one
available input)
• Additional household main socket outlet control
• Power outage monitoring (e.g. RCD trip monitoring)
• Cooling fan switch for over-temperature control
• Connection to a meter with an S0 interface
5.2.1.8 RDC-MD (Residual Direct Current Monitoring Device)
Current Transformer (CT) connection (device variant)
For AC charging system fault monitoring, a charge controller variant is available which
features an integrated RDC-MD which works with an external magnetically shielded me-
asuring current transformer (CT) connected to the CC612. This allows the use of a type A
RCD in the charging system instead of the more expensive type B RCD. The relay in the
CC612 triggers if, during charging, the fault current limit IΔn ≥ DC 6 mA.
The CP terminal is used for Power Line Communication (PLC) in charge
controller variants with this optional integrated feature.
5.2.1.9 Plug lock connection
Under normal operating conditions, the type 2 socket automatically locks the plug when
a vehicle is connected to the charging system. The locking action can be heard. After
disconnecting the plug from the vehicle, the charging system socket automatically
unlocks the charging system socket and the cable can be removed. If both locking and
unlocking work, the socket was correctly attached to the charging system controller. Via
terminals IN , +, OUT, - (i.e. plug lock connections), the charge controller can interface to
different socket/actuator types. Type 2 sockets from various manufacturers and their cor-
responding connection to the charge controller are shown below:
