Comprehensive Standards Coverage

CACTI-EV provides complete conformance testing support for the key EV charging communication standards, implementing all test cases using the original TTCN3 code from the specifications:

  • ISO 15118-4: Conformance test standard for validating ISO 15118-2 (Network and application protocol requirements) implementations
  • ISO 15118-5: Conformance test standard for validating ISO 15118-3 (Physical and data link layer requirements) implementations
  • DIN70122: Conformance test standard for validating DIN 70121 implementations (German standard for digital communication between EVs and charging stations)

Key Features:

  • Complete end-to-end protocol stack testing from physical layer to application layer
  • Testing for all OSI layers through combined ISO 15118-4 and ISO 15118-5 standards
  • Support for both AC and DC charging test cases across all standards
  • V2G communication message sequence verification
  • Protocol timing and error handling validation
  • Plug & Charge and security testing capabilities
  • Combined Charging System (CCS) communication validation
  • Advanced communication logging with protocol-specific analyzers
  • Detailed reporting with comprehensive PICS/PIXIT configuration options

TTCN3 Test Case Implementation

A key strength of our CACTI-EV test system is that it uses the same TTCN3 test case code from the official specifications.

What is TTCN3?

Testing and Test Control Notation Version 3 (TTCN3) is a standardized testing language used for conformance testing of communication protocols. It is specifically designed for testing complex communication systems and protocols, and is the official language used in ISO 15118-4, ISO 15118-5, and DIN70122 standards.

Benefits of Official TTCN3 Implementation

  • Guaranteed compliance with the exact requirements in the standards
  • No deviation from official test procedures
  • Confidence that your implementation is tested exactly as specified
  • Reduced risk of interpretation errors that could occur with recreated tests

PICS and PIXIT Configuration

Our test system provides comprehensive configuration for PICS (Protocol Implementation Conformance Statement) and PIXIT (Protocol Implementation eXtra Information for Testing) parameters, allowing you to customize testing based on your specific implementation:

  • PICS: Define which optional protocol features your implementation supports
  • PIXIT: Set implementation-specific parameters needed for testing
  • Easy configuration through our intuitive interface
  • Detailed documentation on all configurable parameters

Test Monitoring and Reporting

CACTI-EV provides powerful tools for monitoring test execution, analyzing results, and generating comprehensive reports.

Advanced Communication Logging

  • Complete message capture at all protocol layers
  • High-precision timestamps for timing analysis
  • Raw and decoded message formats
  • Real-time log viewing during test execution
  • Log export in multiple formats (CSV, XML, PCAP)

Comprehensive Test Reporting

Our test system generates detailed, customizable reports that provide clear insights into your implementation’s compliance status:

  • Exportable reports in PDF, HTML, and Excel formats
  • Executive summaries for management review
  • Detailed technical reports for engineering teams
  • Message sequence charts for communication visualization
