ECE R10 Conducted Emission (CE-AC) Limits
ECE R10 – REESS Conducted Emissions of charging mode coupled to the power grid
Quick reference for ECE R10 Conducted Emission limits specifically for REESS charging mode coupled to the power grid (CE-AC).
* In the 0.15 to 0.50 MHz range, the limit decreases linearly with the logarithm of the frequency.

ECE R10 REESS Conducted Emission Overview
ECE R10 specifies the electromagnetic compatibility requirements for vehicles and electronic sub-assemblies (ESAs). For electric and hybrid vehicles, the Conducted Emission limits measured on an AC Artificial Network (CE-AC) are specifically applicable to the REESS (Rechargeable Energy Storage System) when it is in charging mode and coupled to the power grid (AC power port).
These regulations ensure that the vehicle's onboard charging system does not inject excessive high-frequency noise back into the public AC power distribution network.
How to read the UN Regulation No. 10 conducted-emission reference
User task
This page isolates the conducted-emission context for an REESS charging connection coupled to the AC power grid under the R10.05 dataset. It is about a charging-mode port and its RF voltage, not the vehicle radiated-emission test.
Choose before comparing
Confirm that the result belongs to the AC charging port and the applicable R10 revision before comparing it. The reference spans 0.15–30 MHz in dBµV with quasi-peak and average detectors; receiver bandwidth, scan step and dwell are revision-dependent, so this CE page does not assign the 120 kHz / 50 kHz / 5 ms conditions used by the separate RE reference. It has no radiated-test distance, and the complete charging setup remains revision-dependent.
What the displayed rows mean
- Charging port and unit
- The CE reference is an AC-port conducted-voltage comparison from 0.15–30 MHz in dBµV, not a radiated field-strength row.
- Detector context
- Quasi-peak and average detectors are separate conditions; the applicable receiver bandwidth, port coupling and charging state must follow the R10 revision and approval plan.
- Vehicle-object boundary
- The page targets REESS charging-mode coupling to the AC grid. It must not be used as a substitute for the vehicle or ESA radiated-emission setup.
Common misread
Do not read this charging-port CE table as a general R10 pass/fail statement. A different charging state, port coupling, revision or radiated setup changes the applicable engineering question.
Reference boundary
EMCCalc uses the UNECE Regulation No. 10 source register and the encoded R10.05 reference data. The applicable revision, approval plan and complete legal test method remain authoritative; no certification claim is made here.
