EMC knowledge route
Plan the standard, laboratory method and optical interface for your EMC test
Connect your EMC test objective with the applicable standard, laboratory method and optical interface. EMC Link transfers supported signals; the configured laboratory system performs the test.
IEC 61851-21-1, IEC 61851-21-2, UN R10 and the relevant IEC 61000 power-quality route.
DUT boundary, controlled counterpart, RF sequence, harmonics, flicker and synchronised evidence.
Transparent optical transfer of released charging communication and signal paths.
EVCA and comframe provide the controlled charging partner, logging, correlation and system workflow.
04 / Standards & Knowledge
Choose the test method for your question
Understand the test method before choosing the tool
Conformance, interoperability and robustness complement each other. Each method answers its own testing question, including when they use the same communication standard.
Does one implementation meet defined requirements?
Structured testing uses defined requirements, preconditions and test cases for one implementation role.
Do independently developed implementations work together?
Testing a real EV and EVSE together reveals their combined timing, option and error-handling behaviour. It adds the interaction of both partners to the findings from isolated tests.
How does the implementation react at boundaries or faults?
Boundary values, delays, missing steps, non-conform behaviour and faults test the reaction beyond nominal operation.
Automated Standards Analysis
Correlate measured values, states, messages and timing with configured normative expectations.
Professional Simulation
Configure supported content, timing and difficult or non-conform charging-partner behaviour.
Charge Playback
Actively reproduce recorded charging-partner behaviour at the physical charging interface.
