CHARX control professional – DC charging controller for fast charging stations

DC charging controllers for fast charging stations

The freely programmable CHARX control professional DC charging controller is the intelligence behind state-of-the-art CCS and CHAdeMO charging stations for mode 4 fast charging in accordance with IEC 61851-23. The controller communicates with the e-vehicle, monitors the charging process, controls parameters such as the charging current, and performs optional additional tasks. Its 3G modem allows convenient remote maintenance. In addition to DC charging, the controller also supports an AC charging point.

cellular interface
To use functions such as user management, billing, and remote diagnostics, use the integrated cellular interface to connect the charging controller to a backend system via OCPP (Open Charge Point Protocol).
cellular interface
Ethernet interfaces
You can use the two Ethernet ports for visualization of the charging process on a touch panel, for programming via PC Worx, and for integration into a charging and load management system.

AC charging interface
To ensure a standard-compliant AC charging process, the controller exchanges the necessary charging parameters with the vehicle via the AC charging interface in accordance with IEC 61851-1.
AC charging interface
CCS charging interface
To enable standard-compliant DC fast charging, the controller exchanges the necessary charging parameters as per DIN SPEC 70121 with the vehicle via the CCS charging interface in accordance with IEC 61851-23.
CCS charging interface
Control of the power electronics
The necessary charging parameters, such as current, voltage, and power, are communicated to the power electronics via the CAN bus interface. To reduce your engineering outlay, we provide ready-made PC Worx function blocks for the CHARX power power modules.

Energy meter connection
To measure energy consumption and bill charging processes precisely, connect AC and DC energy meters via the RS-232 and RS-485 serial interfaces.
Energy meter connection
RFID reader integration
An RFID card reader can be connected via RS-232 or RS-485 so that users can authorize the charging process – either with a backend system or using the local RFID allowlist.
RFID reader integration
Digital I/Os
Additional customer-specific components, such as the control of the DC contactors, evaluation of the insulation monitor, monitoring of the door locking mechanism, or activation of charging status LEDs, can be connected via 16 digital inputs and outputs respectively.
Digital I/Os
The charging controller is programmed by an employee using ready-made function blocks in PC Worx

Wide range of possible applications Freely programmable in accordance with IEC 61131

CHARX control professional can be freely programmed for your individual charging application in accordance with IEC 61131. This makes it a versatile charging controller for the widest possible range of applications.
