CCS Listener simplifies analysis of charging communication

Vector in Germany has launched a test system to simplify the analysis of CCS charging communication.

The VH5110A CCS Listener is connected to an inductive coupler that is placed around the charging cable for fast deployment in the field. The CCS Listener can also be used for continuous recording of in-vehicle charging communication with a data logger.

Charging station manufacturers and operators as well as automobile manufacturers benefit from this hardware. The CCS Listener has already proven itself in the market for two years and offers passive, interference-free “listening” to the CCS charging communication between e-vehicle and charging station (DIN 70121, ISO 15118, IEC 61851).

The analysis of the data communication takes place without man-in-the-middle intervention. Communication is not affected during analysis, because the PLC signal can even be tapped indirectly via an inductive coupler without a connection to the signal-carrying Control Pilot in the charging cable. This way, users also avoid complex isolation from the high voltage. The communication is displayed in the CANoe analysis software.

This helps improve interoperability between the charging infrastructure and e-vehicles, both in the field for short-term analysis, for example in the event of charging interruptions, and for continuous recording of charging processes in conjunction with a data logger in the test vehicle. The CCS Listener hardware fits in any laptop bag and is ready for immediate use on site.

The hardware has been revised with an extended input voltage range of 9 to 36 volts, so the CCS Listener can be connected directly to the vehicle’s electrical system regardless of the voltage – an advantage especially for the analysis of charging communication in commercial vehicles. Another new feature is the LED status display, which allows users to see whether the device is in operation and also provides information about the status of the communication.
