Analysis of e-Vehicles Charging Communication

18 October 2022 – With the “CCS Listener” VH5110A, Vector simplifies the analysis of CCS charging communication. Charging station manufacturers and operators as well as automobile manufacturers benefit from this hardware. Connected to an inductive coupler that is simply placed around the charging cable, the analysis hardware is ready for fast deployment in the field. But the CCS Listener can also be used for continuous recording of in-vehicle charging communication with a data logger.

The handy 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 special feature of the hardware: 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.

With the CCS Listener, Vector is helping to continuously improve interoperability between the charging infrastructure and e-vehicles. This applies to 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: plug it in, switch it on and the analysis can begin.

The hardware has been revised and is now available as version VH5110A. The new features make the device even more robust and the application even more user-friendly: Thanks to the extended input voltage range of 9 to 36 volts, 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.

Whether for acute problem analysis in the field or for systematic improvement of interoperability, as a specialist, the VH5110A CCS Listener scores with its wide range of applications and ease of use.
