EMC Link: Charging Communication through the EMC Chamber
Connect the charging signals inside an EMC chamber to equipment outside through an optical link. EMC Link carries the supported signals; the external instruments and test system perform the measurements and analysis.
Charging-specific optical interface
The chamber link is a product boundary, not a generic converter.
A conventional chamber layout places the DUT (device under test) inside while the charging counterpart, operator interface and analysis system should remain outside. EMC Link addresses that boundary with a chamber-side unit, external unit and optical connection engineered around the charging interface.
It transports the released paths transparently. EVCA and comframe provide simulation, logging, analysis, debugging and orchestration when included in the system. EMC Link itself does not decode, manipulate or simulate the charging protocol.
EMC Link architecture
Keep the DUT in the chamber and the test intelligence outside.
The published setup uses two optical fibre cables and a filtered 12 V DC supply for the chamber-side unit. The charging counterpart, operator interface and optional EVCA analysis stay outside the interference zone.
DUT inside
EV, inlet, EVCC (vehicle-side charging communication controller), EVSE (electric vehicle supply equipment, or charging station), SECC (station-side charging communication controller) or defined interface under the chamber condition.
Chamber-side unit
Connects the released charging paths and filtered local supply.
Optical connection
Two fibre cables connect in and out of the chamber.
External unit and test system
Real partner or EVCA, comframe, operator interface and evidence outside.
Where EMC Link fits in the standards test setup
Preserve the charging boundary. Leave stimulus, measurement and verdict to the approved laboratory systems.
EMC Link is not the EMC receiver, field generator, artificial network, grid simulator, harmonic analyzer or flickermeter. Its job is to keep the selected charging interaction transparent between the DUT and the controlled counterpart.
Vehicle and onboard charger
Keep the EVSE-side counterpart and charging communication available while the complete vehicle or vehicle-side electronic subassembly is tested.
Off-board charging equipment
Keep the EV-side counterpart outside while the charging station, SECC or off-board subsystem is operated in the required mode.
Vehicle approval context
Support the defined charging harness and active operating state. The exact regulatory series, annex and laboratory geometry remain part of the approval plan.
Harmonics and flicker
Maintain communication while dedicated grid and measurement equipment evaluates AC mains behaviour. EMC Link does not create the power-quality result.
Four practical topologies
Use the same optical product boundary with real or simulated partners.
Real EV and real EVSE
Standalone operation keeps both real implementations active.
Real EV with EVSE simulation
Vehicle-side chamber test with a controlled charging-station counterpart outside.
Real EVSE with EV simulation
Charging-station-side chamber test with a controlled vehicle counterpart outside.
Interface validation
Simulation-to-simulation and component-level setups for a defined boundary.
Transparent signal transport
Carry the charging-specific context through optical media.
The applicable path depends on the selected charging technology and released module configuration.
PLC communication
High-level powerline communication for applicable charging technologies.
Low-level charging signals
Control Pilot (CP)/Proximity Pilot (PP), CS1/CS2, CC1/CC2, CE/ID and temperature according to configuration.
Auxiliary handling
Relay contact for digital control of the opposite-side 12 V auxiliary environment where configured.
Ethernet and CAN
Supporting data paths for the selected test architecture.
Preserve the signal paths the charging interaction actually needs

PLC charging communication through the optical path
- Low-level charging signals
CP / PP · CS1 / CS2 · CC1 / CC2 · CE / ID · temperature

EVCA and comframe logging, analysis, simulation and evidence
Standalone or integrated
Use EMC Link alone or connect the complete EVCA evidence workflow.
Real EV and real EVSE remain the partners.
Use the optical link to preserve the supported charging paths across the chamber boundary without adding a simulation system.
EVCA provides the real or simulated counterpart.
Add comframe logging, analysis, debugging and simulation control outside the chamber according to the selected EVCA configuration.

Product boundary and technical scope
Keep transport, test intelligence and charging power as separate responsibilities.

|---|---|---|---|
| Charging communication | Transparent transfer of released PLC and supporting paths | Decoding, analysis, manipulation and simulation by EVCA/comframe | Protocol and software release must match the selected modules |
| Low-level signals | Technology-specific transport of configured signal paths | Test logic, stimulus and verdicts by the connected system | CP/PP, CS1/CS2, CC1/CC2, CE/ID and temperature are technology-dependent |
| Chamber connection | Chamber-side unit, external unit and two optical fibres | Feedthroughs and facility integration by the laboratory | Routing and filtered 12 V supply must be defined before installation |
| Charging power | No power conversion or high-power transfer | Sources, loads, cables, cooling, interlocks and safety systems | Power architecture remains a separate approved workstream |
| Evidence | Preserves the communication path | Logging, correlation, automation and reports by EVCA/comframe | Required channels and output must be specified with the application |
| Standard and verdict | Keeps the defined charging interaction available during the test | RF generation, receivers, artificial networks, grid and power-quality instruments, laboratory assessment and approval | Exact document, edition, series, DUT mode, limits and verdict method remain external to EMC Link |

The public brochure identifies PLC, technology-specific low-level signals, temperature and auxiliary handling, Ethernet and CAN. The actual set depends on the selected technology and released configuration.
How many optical fibre cables are used?
The published chamber setup uses two optical fibre cables to connect into and out of the chamber.
How is the chamber-side unit powered?
The public brochure describes a filtered 12 V DC supply inside the chamber. The exact facility connection and filtering remain part of the approved laboratory integration.
Which charging technologies are covered?
The public brochure lists AC, DC CCS Combo 1 and Combo 2, NACS, CHAdeMO and GB/T DC. MCS is available separately.
