EVCA Interop: EV Charging Interoperability Testing
Record a real vehicle and charging station together when a charge fails. Compare messages, voltage and current on one timeline, then select any additional functions needed to investigate the suspected cause.
Focused EV charging interoperability test system
A concrete system for real EV-to-EVSE charging troubleshooting.
EVCA Interop investigates how a specific EV and EVSE (electric vehicle supply equipment, or charging station) behave together under real operating conditions. Select the configured access, measurement and analysis functions for the pair, then review controlled validation options separately.
EVCA Interop also supports EV and EVSE simulation at ComOnly level: charging communication and supported low-level signals, without a connected load circuit. Select the charging technology, connectors, test direction and measurement channels for your application.
Product-specific Man-in-the-Middle topology
See the full charging interaction.
Connect EVCA Interop between the real vehicle and charging station. Record communication, voltage and current on one timeline while both charging partners remain connected.
Real field conditions.
Measure the interaction that actually failed.
Capture the concrete pair at the site instead of reconstructing the event from exported logs, separate clocks and incomplete views.
Depending on the selected configuration, comframe links charging communication (PLC, SLAC and HLC), Control Pilot (CP)/Proximity Pilot (PP)/PWM signals, CAN and device data, voltage, current and power, and stop events and reactions to the same charging session. The real vehicle and charging station remain the active partners.

Cross-Layer State Monitoring
See the first meaningful deviation, not only the final error.
EVCA Interop connects high-level communication, low-level signaling and electrical behaviour on one time base. Cross-Layer State Monitoring checks whether the technology-specific messages, states and measured values form an allowed and technically consistent combination at the relevant point in the charging process.

- 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.
Exact panels, protocol versions, measured channels and automatic evaluation rules depend on the selected EVCA Interop hardware and released comframe configuration.

EVCA Interop product questions
What is EVCA Interop?
EVCA Interop is a mobile EV charging interoperability test system placed between a real EV and a real EVSE. It captures and correlates both implementations, supports controlled validation where configured and preserves the case for laboratory transfer.
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.
