Harnessing Communication Monitoring Tools for Advanced CCS Protocol Conformance Testing
Fueled by the burgeoning electric vehicle (EV) market, traditional car manufacturers are introducing a broad array of EV models to satisfy increasing demand. At the same time, governments worldwide are actively expanding charging infrastructure to accommodate the rapidly growing EV fleet. Against this backdrop, seamless compatibility between different EVs and EV supply equipment (EVSE) becomes a critical factor for a positive user experience.
Protocol conformance testing plays a vital role in ensuring this interoperability. The conformance testing specifications for the CCS (Combined Charging System) used in Europe and the United States include:
While comprehensive conformance testing can improve interoperability, doing it well is no easy feat. Test personnel or test system developers must have specialized communication expertise and understand the detailed test scenarios outlined in the standards. Additionally, the CCS conformance specifications define hundreds of test cases for EVs and EVSE, making setting up a test system and verification-related work a time-consuming endeavor.
Why Communication Monitoring Tools Are Important
In addition to verifying the correctness and timing of the communication parameters of the device under test (DUT), conformance testing also validates the accuracy of the scenarios simulated by the test system. Therefore, when analyzing communication issues, real-time data monitoring tools are often necessary to track critical communication parameters. These serve as essential debugging tools for testing engineers or developers in their analysis work.
