11 Conclusion

After connecting the EVCC Simulator (Electric Vehicle) and the SECC (Charging Station equipped with the integrated OCPP and ISO stack), we were able to conduct end-to-end compliance and operational testing.

This setup enabled the execution of ISO 15118-dependent test scenarios as part of the OCPP compliance testing, including TC_K_53_CS, which validates ISO 15118 Plug & Charge certificate handling and contract authorization via OCPP 2.0.1.

Validating such test cases ensures full interoperability, seamless authentication and robust protocol communication before deployment to real-world charging infrastructure.
