EMC Link inside an EMC test chamber

Charging interfaces for EMC testing

EMC Link: optical charging interface for EMC testing

Keep the DUT inside the EMC chamber and its simulated charging counterpart outside. Connect their configured charging signals with EMC Link, which transports the signal paths transparently through optical fibres.

  • Optical charging communication
  • Real or simulated charging partners
  • Test equipment outside the chamber

Architecture and test setups

DUT in the chamber, simulation and analysis outside

Match the chamber-side and external units to the device under test (DUT) and its charging counterpart.

Inside the chamber

The DUT and compact EMC Link unit, with a filtered 12 V DC supply for the chamber-side unit.

Optical connection

Two optical fibre cables connect the chamber-side and external units.

Outside the chamber

Connect the external unit to the simulated charging counterpart. Use a compatible EVCA/comframe configuration for simulation, operation and analysis.

Configured signal paths

Select signal paths for your charging interface.

Configure the signal paths for the charging technology and released modules used in your test setup.

PLC communication

High-level powerline communication for applicable charging technologies.

Low-level charging signals

CP/PP, CS1/CS2, CC1/CC2, CE/ID and temperature, according to the selected configuration.

Auxiliary handling

A relay contact for digital control of the opposite-side 12 V auxiliary environment, where configured.

CAN and Ethernet

Supporting data paths for the selected test architecture.

How the components work together in the test setup

Optical signal transport
EMC Link and the selected modules carry the released signal paths transparently.
Simulation and analysis
Use the connected test system for simulation, protocol decoding, manipulation, logging and automation. A compatible EVCA/comframe configuration provides these functions when included in the setup.
Charging power and safety
External sources, loads and laboratory infrastructure provide power conversion, charging power, cooling and safety functions. EMC Link does not transfer charging power.
EMC measurement and assessment
The laboratory provides the stimulus, instruments, limits and assessment according to the agreed test plan. EMC Link does not produce an EMC compliance verdict.

Technology-specific modules

Choose the charging technology and matching modules.

Specify the modules, connectors and software compatibility for the agreed configuration. Use software-controlled selection within the supported scope.

AC

Control Pilot and proximity paths for charging-state behaviour.

CCS

Combo 1 and Combo 2, with the configured low-level paths and PLC communication.

NACS

Configured charging signal paths and PLC communication.

CHAdeMO

Technology-specific low-level signals and CAN communication.

GB/T DC

CC1/CC2, CAN and the configured interface signals.

Standards and test scope

Define the applicable EMC test requirements.

Select the standard and operating conditions for the device under test. The released edition and laboratory test plan determine the method.

IEC 61851-21-1

Vehicle and onboard charger

EMC requirements for vehicle-side charging units, tested in the complete vehicle or as an electronic subassembly within the applicable scope.

IEC 61851-21-2

Off-board charging equipment

EMC requirements for external EV charging systems and their applicable operating modes.

UN R10 / ECE R10

Vehicle approval context

Specify the regulatory series, annex, active charging state and required laboratory geometry in the approval plan.

IEC 61000-3

Harmonics and flicker

Dedicated grid and measurement equipment evaluates AC mains behaviour. EMC Link maintains the configured communication path.

Selection and installation

Configure EMC Link for your test setup.

When do I need EVCA?

Use a compatible EVCA/comframe configuration to simulate the charging partner, analyse protocols, record results or automate control as required by the test. EMC Link connects the signal paths optically; the connected test system performs simulation and analysis.

What is required for chamber installation?

Plan two optical fibre cables, suitable feedthroughs and a filtered 12 V DC supply for the chamber-side unit. The laboratory defines the cable routing, filtering, external power and safety integration for the approved setup.

Are all charging technologies included in a base configuration?

The included technology paths depend on the selected modules, connectors and compatible software. The quotation defines the released scope. MCS follows a separate product and configuration path.

Configure your test setup

Define your EMC Link configuration with these five test-setup details.

  1. DUT, standard and operating condition

    Describe the vehicle, OBC, inlet, controller, EVSE or module under test. Specify the applicable standard edition and test mode.

  2. Charging counterpart

    Choose EVSE simulation for a vehicle-side DUT or EV simulation for a charging-station-side DUT.

  3. Technology and signal scope

    Specify the connector family and the required PLC, low-level signals, CAN, Ethernet, temperature and auxiliary paths.

  4. Chamber integration

    EMC or climate chamber, fibre routing, feedthroughs, filtered 12 V supply, artificial network/AAN, harness geometry, external power and safety.

  5. Evidence and software

    Specify compatible test-system functions for logging, analysis, control and reporting, including EVCA/comframe where configured.
