2.3 Product description
The charge controller monitors the internal hardware of charging systems such as the meter, the user inter-
face module or the socket-outlet. It can be operated as an "always-on system" that is always connected to a
mobile network. The variants with a 4G modem support the 4G mobile phone standard.
Communication with a backend system is possible via the OCPP application protocol. 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 (e.g. has-to-be, Virta and NewMotion) have
been carried out successfully.
Refer to "Ordering details" for product variants.
2.4 Functional description
The charging system consists of an RCD type A and a contactor. These are directly connected to a type 1 or
type 2 socket-outlet, or to an attached cable with a type 1 or type 2 plug (see chapter "Charging system with
type 2 socket-outlet").
2.4.1 General functions
• The charging system can be equipped with a meter. A Modbus meter is required for digital reading
of the energy consumption. The Modbus RTU wires are attached directly to the charge controller.
Alternatively, a meter can be connected to an Ethernet interface via Modbus TCP.
• An AC 230 V power supply is needed for operation.
• An RFID module can be used for easy user interaction.
• Power flow toward the vehicle is enabled by enabling the contactor via an integrated 230 V control
relay in the charge controller.
• Using a micro SIM card (not included in the scope of delivery):
The SIM card slot (available on data gateways with a 4G modem only) is located on the printed cir-
cuit board (terminal E) of the charge controller. The SIM card can have a PIN number which can be
configured via the Operator tab. The APN settings for the SIM card can also be configured via the
Operator tab.
• Data gateways with a 4G modem feature an SMA connector for a 4G antenna on the printed circuit
board.
• For fault current detection in an AC charging system, the charge controller features an integrated
residual direct current monitoring module (RDC-M) which uses an externally connected current
transformer. With the integrated monitoring of the DC fault current, only an RCD type A is required
in the charging system.
• Data exchange between the electric vehicle and the charging system is possible via ISO 15118 com-
pliant Powerline Communication (PLC).
• 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 in the mains supply. Maximum number of charging
points in a network: 250.

ICC1324_D00436_00_M_XXEN / 05.2022 9
ICC1324 charge controller
• 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
DC fault current ≥ 6 mA.
– 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.
i
The charge controller with a residual direct current monitoring module (RDC-M) only works in combination
with a measuring current transformer (to be ordered separately).
2.4.2 Load current and cooling control
(temperature monitoring)
The charge controller is equipped with a temperature sensor, which allows the temperature in the environ-
ment of the charge controller to be estimated. Based on this estimation it is possible to dynamically reduce
the charging current or even suspend charging. This feature can serve to maintain the temperature inside the
charging system within the permissible range for the components used in a charging system. Two tempera-
ture thresholds for charging current reduction and charging interruption can be set via the Manufacturer tab.
i
The actual temperature is affected by heat generated by the controller itself.

ICC1324 charge controller
4.3 Connectivity
4.3.1 Master/slave connection
The charge controller serves as a data gateway. The master becomes the OCPP backend for the slave.
It connects each slave as an additional charging point to the backend.
The master or slave role is assigned to a charge controller within the Manufacturer configuration interface. A
reboot can then be triggered and the devices can be connected via USB cable (master: USB type B / slave: USB
type A). Usually, the devices connect automatically. Local access to the master/slave combination is then only
possible via the slave device. The IP address of the master must be assigned to each slave as OCPP host name.
Port 1600 must be used as OCPP port for establishing the connection with the master.
The additional IP address 192.168.125.124 is assigned to the master via the Operator tab (without assigning a
default gateway). The slave uses the IP address 192.168.125.125 to establish a connection with the master.
Master and slave configuration can be accessed via a selection page on the configuration website of the slave
(e.g. http://192.168.123.123).
4.3.2 USB configuration interface (CONFIG)
The USB configuration interface (CONFIG) on the PCB (terminal H) of the charge controller is connected to a
conventional laptop, PC or tablet computer via USB cable (type B). This interface allows local configuration of
the charge controller. In addition, it enables the installation of software updates (for a configuration descrip-
tion, refer to chapter "Configuration and testing"). The web interface can be accessed via the IP address
192.168.123.123 when the charge controller has fully booted.
4.3.3 Ethernet interfaces
The charge controller can be connected to an existing Ethernet network via the two Ethernet interfaces. For
further information, refer to chapter "Configuration and testing".
i
Use a shielded Ethernet cable.
4.3.4 WiFi interface (depending on the variant)
The integrated WiFi module makes it possible to set up a WiFi network. It also enables a connection to the
backend. For further information, refer to chapter "Configuration and testing".
4.3.5 LED service
The service LED on the PCB (terminal F) can be used for service purposes and indicates the following system
states:
System is starting
System started, not ready for operation yet
System ready for operation
System error
4.3.6 230 V power supply
The charge controller is supplied with power by means of an AC 230 V power supply via an integrated power
supply unit.

16 ICC1324_D00436_00_M_XXEN / 05.2022
Connection
4.3.7 Contactor connection
The charge controller controls the contactor, which in turn controls the power flow toward the vehicle. The
contactor is controlled via a relay in the charge controller, the contacts of which are rated for 230 V/4 A.
4.3.8 Weld check
By means of the measuring lines WA/WB (terminal designation) an impermissible closing of the contactor
contacts, e.g. welding/sticking, can be detected.
Wiring diagram
I risk of a short circuit! According to DIN VDE 0100-430, devices for protection against a short circuit can be
omitted for the coupling of terminals WA and WB if the wiring is carried out in such a manner as to reduce
the risk of a short circuit to a minimum. (A short-circuit-proof and earth-fault-proof wiring is recommend-
ed). The connecting lines WA and WB to the system to be monitored must be designed as spur lines. No
load current may be conducted through the terminals.

Connection
4.3.10 PE monitoring
The PE monitoring checks whether there is a connection from the charge controller to PE. For this purpose,
WA must be connected to L1. The cable length is limited by its capacitance per unit length. To ensure proper
functionality of the PE monitoring, L1 must be tapped downstream of the measuring current transformer and
upstream of the power contactor (see wiring diagram).
I Pe monitoring does not replace tests (example: protective conductor resistance).
I the Ethernet shield and the USB shield are directly connected to PE. This must be taken into account in
the test!
I hV test: WA is coupled to PE via a protective circuit and with approximately 80 kΩ. Above 500 V, a leak-
age current flows to PE. Test voltages above AC 1000 V/1 sec. are not permissible!

4.3.11 Control Pilot (CP) and Proximity Pilot connections (PP)
The Control Pilot (CP) and Proximity Pilot (PP) contacts connect the charge controller to the socket-outlet, en-
abling it to communicate with the vehicle and the cable plug. The PP contact detects the presence of the plug
and the CP contact exchanges control signals between the electric vehicle and the charging station (see IEC
61851).
i
PP is not required if the charging cable is permanently attached.
4.3.12 I/O extension
The charge controller features two configurable, two-channel I/O interfaces each consisting of an optocoupler
input and a relay output (connector sockets K and L).
• Parking management interface (the supported communication protocol is proprietary to Scheidt &
Bachmann and is based on the available auxiliary relay and one available input)
• Additional SCHUKO socket-outlet control
• Power outage monitoring function (e.g. RCD trip monitoring)
• Heating switch/cooling fan switch for overheating protection
4.3.13 Emergency opener
The emergency opener is integrated as a circuit group in the charge controller. In the event of a power failure,
the plug of the charging cable is automatically unlocked so that it can be removed.
4.3.14 Residual direct current monitoring module (RDC-M)
For residual current detection in an AC charging system, an integrated residual direct current monitoring
module (RDC-M) is used. This module uses an external magnetically shielded measuring current transformer.
This allows the use of a residual current device (RCD) type A instead of an RCD type B. The relay in the charge
controller is de-energised if, during the charging process, a fault current IΔn ≥ DC 6 mA flows. The measured
fault currents RMS/DC are made available to the backend system via OCPP message.
4.3.15 Connectivity with Modbus meters
The use of a meter is not mandatory. It is necessary if measured values are required during normal operation
(e.g. in the DLM). The meter is connected to the Modbus meter interface (terminal A) of the charge controller.
Various Modbus meters are currently supported, including:

Meter Slave ID Baud rate Parity Data Bit Stop Bit
1 9600 N (none) (except Saia) -> even 8 1
Additional Modbus meters can be included in future software updates upon customer request. Refer to the
Manufacturer tab on the web server for a list of supported Modbus meters.
The Modbus meter interface is terminated with a terminating resistor of 120 Ω.
4.3.16 Gateway variants with modem
The charge controller supports 4G mobile networks. A 4G modem is integrated into the device. It uses a wire-
less module, which supports the following European frequency bands (depending on the variant, refer to
technical data):

20 ICC1324_D00436_00_M_XXEN / 05.2022
Connection
• LTE FDD: 800 MHz band 20, 900 MHz band 8, 1800 MHz band 3, 2100 MHz band 1 and 2600 MHz
band 7
• GSM: 900 MHz band 8 and 1800 MHz band 3
• WCDMA: 850 MHz band 5, 900 MHz band 8, and 2100 MHz band 1
• The charge controller can be operated as an "always-on system" when connected to a mobile net-
work.
• Connection is only possible when a SIM card is inserted in the SIM card slot located on the PCB (ter-
minal E) of the charge controller.
• The SIM card can have a PIN number which can be configured via the Settings tab.
• The APN settings for the SIM card can also be configured via the Settings tab.
I Caution! Damage to the SIM card slot by nano SIM cards! The use of nano SIM cards with a SIM card
adapter may damage the SIM card reader. Therefore, it is recommended to use only micro Sim cardS.
i
The SIM card can be inserted/removed via the hinged insertion & ejection mechanism.
Use in the EU and other countries
The use of device variants with an integrated 4G modem is only possible in member states of the European
Union, in Lichtenstein, Iceland, Norway, Switzerland, Andorra, Monaco, San Marino and the United Kingdom.
i
If 4G mobile networks are not supported, GSM mobile networks may also be used.
4.3.17 Antenna socket
The antenna socket allows connection to a 4G antenna (not included in the scope of delivery).
