2.1 Intended use
The ICC1324 charge controller, hereinafter referred to as "charge controller", is the main component of a
charging system. It is intended for use in charging stations and wallboxes for electric vehicle charging. The
charge controller controls type 1 and type 2 socket-outlets as well as attached cables. It enables a setup that
complies with the requirements of current standards, e.g. IEC 61851-1 and IEC 62955.
2.2 Product features (depending on the variant)
• Charge controller in accordance with IEC 61851-1 (mode 3 charging)
• Master and slave operation configurable
– Setting up charging stations with two charging points: 1 charge controller as data gateway with
4G modem and 1 charge controller as slave without 4G modem
• Dynamic load management to optimally distribute the available power among all charging points
and signal the maximum power to the vehicle
• Patented residual direct current monitoring module (external RCD type A required), different cable
lengths can be selected
• Integrated emergency opener for actuator control (locking/unlocking)
• Can be integrated in single- or three-phase systems up to 3x 32 A
• OCPP 1.5 and OCPP 1.6 compliant with JSON, SOAP
• Integrated 4G modem
• 3 USB interfaces:
– 1 CONFIG interface (type B) for local configuration and installation of software updates
– 2 USB host interfaces (type A)
• Control Pilot and Proximity Pilot communication (acc. to IEC 61851-1)
• Additional SCHUKO socket-outlet control
• Meter interface: Modbus TCP and RTU
• External Modbus interface for remote control via energy management systems
• Additional inputs and outputs for extended control of the charge controller
• Internal temperature sensor to reduce the charging current depending on the ambient tempera-
ture
• ISO 15118 Powerline Communication (PLC) for plug & charge, autocharge and load management
systems

8 ICC1324_D00436_00_M_XXEN / 05.2022
Function
• Integrated WiFi module and two Ethernet interfaces
• Integrated DC 12 V voltage source for customer-specific applications
• Supply voltage AC 230 V
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.
