Cross-Layer State Monitoring
Locate deviations in the charging sequence
comframe brings decoded communication, synchronised timelines and technology-specific state views together. Cross-Layer State Monitoring checks whether messages, low-level signals, states and electrical measurements form an allowed combination at each stage of charging.
- High-level communicationMessage direction, content, sequence and timing.
- Low-level signalingTechnology-specific control, connection and stop states.
- Electrical behaviourVoltage, current, power transition and partner reaction.
- Expected contextConfigured or normative phase, allowed combination and highlighted deviation.

EVCA Interop product questions
What is EVCA Interop?
EVCA Interop is a mobile EV charging interoperability test system connected between a real EV and a real EVSE. It records communication and configured electrical measurements on a shared time base. Use the released analysis and validation functions to investigate the interaction and keep the case for laboratory tests.
Does EVCA Interop replace the EV or charging station?
In passive Man-in-the-Middle operation, the vehicle and charging station remain connected and communicate with each other. EVCA Interop can also simulate the EV or EVSE at ComOnly level, using charging communication and supported low-level signals. No load circuit can be connected, so these simulation modes do not provide charging-power tests. Supported functions depend on the selected configuration and software release.
How is EVCA Interop different from a charging sniffer?
A charging sniffer records communication. EVCA Interop combines communication with configured low-level signals, timing, electrical measurements and charging-state context on one synchronised timeline. Selected configurations add standards-aware evaluation, controlled manipulation or Charge Playback.
Which technologies support Cross-Layer State Monitoring?
Cross-Layer State Monitoring is available in applicable configurations for DC CCS, CHAdeMO and DC China / GB/T DC. Exact protocol versions, state models, channels and evaluation rules depend on the selected EVCA hardware and comframe release.
Can EVCA Interop support CCS interoperability testing?
Yes. CCS is the documented core path, including applicable IEC 61851 signaling, PLC and SLAC, DIN 70121 and ISO 15118 context. Exact connectors, TLS functions, certificates and ISO 15118-20 scope must be confirmed for the quoted release.
Can EVCA Interop address CHAdeMO and GB/T DC?
Yes, through selected configurations with the appropriate connector hardware, CAN communication, low-level state access and released software functions. The quotation defines the actual technology and version scope.
