Overview - EN IEC 61851-21-2:2021 (EMC for off‑board EV charging)
EN IEC 61851-21-2:2021 specifies the electromagnetic compatibility (EMC) requirements for off‑board components and equipment used to supply or charge electric vehicles (EVs) by conductive power transfer (CPT). It applies to equipment with rated input voltages (per IEC 60038) up to 1 000 V AC or 1 500 V DC and output voltages up to the same limits, and covers charging modes 1, 2, 3 and 4 defined in IEC 61851-1. This edition is an EMC‑focused technical revision that refines port definitions, test setups, limits, operation modes and adds normative annexes (A–F).
Key topics and technical requirements
- Scope and ports: Defines test ports typically found on off‑board charging equipment (power input, CPT/vehicle connection, wired network/signal ports, enclosure).
- Emissions: Limits and test procedures for low‑frequency (LF) and radio‑frequency (RF) disturbances, including:
- Harmonic current limits and assessment (references to IEC 61000 series)
- Voltage fluctuations and flicker limits
- Conducted emissions on power and CPT ports (150 kHz–30 MHz)
- Radiated emissions from enclosures (above 30 MHz)
- Immunity: Required immunity tests and performance criteria (A/B/C) for typical disturbances:
- Electrostatic discharge (ESD), radiated RF, conducted RF immunity
- Electrical fast transients (EFT), surge immunity and voltage dips/interruptions
- Power‑frequency magnetic field immunity
- Test methods and setups: Detailed test plans, environmental/test conditions, termination and coupling methods (including Impedance Stabilization Networks for communication lines and PLC coupling arrangements).
- Reporting and annexes: Test report requirements and six annexes with example test setups, port terminations, surge/transient test arrangements and informative guidance (e.g., keyless‑entry radiated disturbance).
Applications - who uses this standard
- EV charging station manufacturers and off‑board equipment OEMs - for EMC design, pre‑compliance and final compliance testing.
- Automotive OEMs and EV subsystem suppliers - to verify vehicle/charger interoperability and EMC behavior at CPT connection.
- EMC test laboratories and certification bodies - to execute standardized emission and immunity tests.
- Procurement/specification engineers, utilities and regulators - to define acceptance criteria and ensure conformity with harmonized EMC requirements.
- System integrators and R&D teams - to guide mitigation (filtering, screening, surge protection) during product development.

cable.
The contents of the standards referenced in this document are not repeated here; however
modifications or additional information needed for practical application of the measurements
of EUT’s is given in this document.
– 12 – IEC 61851-21-2:2018 © IEC 2018
The tests shall be carried out within the specified operating range of the EUT and at its rated
supply voltage.
Test setups according to Annex A shall be used for the immunity and emission tests above
150 kHz.
In-cable control and protection devices (IC-CPDs), other portable equipment and mode 2
equipment shall be tested as per table top equipment.
4.3 Termination of the EUT during testing
All ports of the EUT shall be terminated with ANs/ISN or respectively CDNs as appropriate.

The immunity requirements are specified in Table 1, Table 2, Table 3 and Table 4 according
to the type of power input (AC or DC) and environmental classification (residential or non-
residential) of the EUT to be tested.
Testing shall be performed in the following two operating modes:
• waiting mode: to simulate when the EUT is fully powered up and connected to a vehicle
but not charging (for example, when the batteries are fully charged or if waiting for the
power grid to decide when to charge);
• charge mode: during testing, the EUT shall be operated at 20 % of the maximum rated
power ±10 %. If this is not possible according to IEC 61851-1:2017, the percentage may
be raised.
It has been considered that no assessment is required when no load is connected since
waiting mode adequately addresses this mode of operation.
In-cable control and protection devices (IC-CPD) shall be tested as off-board AC charging
equipment.
The mode of operation shall be specified and the actual conditions, during the tests, shall be
precisely noted in the test report.
4.4.3 Emissions
Emission requirements are specified in Table 7 to Table 14 and Table 16 to Table 19.
Testing shall be performed in the following operating modes:
