Charging Communication Testing

Efficient. Seamless. Comprehensive.

Charging communication is a key enabler of reliable and safe e-mobility. The Vector Charging Communication Testing Solution provides a holistic toolchain to analyze, simulate, emulate, and test communication between electric vehicles (EV) and charging stations, also known as electric vehicle supply equipment (EVSE) – from early development to full system validation.

Ensure interoperability, compliance, and performance of your charging solutions, while reducing development effort and time-to-market.

Gain Full Transparency

Analysis is the foundation for reliable charging communication. It enables you to gain full visibility into the interaction between electric vehicles (EV) and charging stations (EVSE) in both development and real-world environments. With Vector’s solution, you can capture and evaluate CCS and NACS communication on the control pilot line, including the low-level PWM communication. This makes it possible to identify protocol deviations, timing issues, and unexpected behavior. The tools support both lab-based debugging and field data analysis, allowing you to validate real charging sessions under realistic conditions. By combining detailed signal measurement with protocol-level insights, developers can efficiently trace errors to their root cause. The analysis capabilities integrate seamlessly with simulation and testing workflows, enabling a continuous validation process across all stages.

What You Achieve

  • Analyze CCS- and NACS-based communication behavior

  • Capture field data and evaluate real charging sessions

  • Identify protocol deviations and performance bottlenecks

Enable Early Development

Simulation allows you to develop and validate charging communication logic long before physical hardware becomes available. With Vector tools, you can simulate both EV and EVSE behavior and configure them flexibly to represent different charging scenarios. This enables developers to test communication flows, parameter variations, and system interactions in a controlled environment. Simulation is particularly valuable for validating new features, testing edge cases, and reproducing issues without the need for complex hardware setups. By integrating simulation into your development workflow, you can shift testing activities to earlier phases and significantly reduce iteration cycles. The simulated components can also serve as intelligent communication partners for control units, supporting continuous integration and automated testing. As simulation models can be reused and extended, they provide a scalable foundation for long-term development.

What You Achieve

  • Early validation without dependency on physical hardware

  • Flexible testing of communication scenarios and variants

  • Reduced development effort through reusable simulation setups

Ensure Compliance and Interoperability

Testing ensures that charging communication meets all functional and regulatory requirements. Vector provides automated test environments that enable systematic validation of EV and EVSE implementations against international standards such as CCS, NACS, MCS, GB/T, and CHAdeMO. Predefined test case libraries cover relevant conformance and interoperability scenarios, helping teams ensure compliance efficiently. Automated execution allows repeated testing across software versions and system configurations, increasing reliability and reducing manual effort. In addition to functional testing, the solution supports robustness and security validation to identify vulnerabilities early. Testing can be executed across different integration levels, from software-based environments to hardware test systems. This consistency ensures traceability and comparability of results throughout the development lifecycle.

What You Achieve

  • Automated validation of conformance and interoperability

  • Reduced risk of integration issues and compliance gaps

  • Scalable and repeatable testing across development stages

Validate Realistic System Behavior

Emulation enables realistic validation of charging communication by combining virtual and physical components. With Vector’s solution, you can emulate EV or EVSE behavior and integrate it into complex system setups. This allows you to reproduce real charging scenarios and validate system interactions under dynamic conditions. Emulation is particularly useful for testing integration scenarios where complete systems are not available or need to be replaced by controllable counterparts. By bridging the gap between simulation and physical testing, emulation provides a flexible environment for system-level validation. It also supports Hardware-in-the-Loop (HIL) and Software-in-the-Loop (SIL) approaches, ensuring consistent testing across all integration levels. As a result, teams can verify system behavior more efficiently and reduce dependency on physical availability of EV or EVSE.

What You Achieve

  • Realistic validation of system behavior under dynamic conditions

  • Flexible integration of virtual and physical components

  • Reduced dependency on availability of real DUT counterparts
