This document defines limits for 3 m measurement distance and methods of measurement that are designed to provide protection for off-board receivers (at 10 m distance) in the frequency range of 150 kHz to 30 MHz when used in the residential environment.
NOTE Protection of receivers used on board the same vehicle as the disturbance source(s) is covered by CISPR 25.
This document applies to the emission of electromagnetic energy which might cause interference to radio reception and which is emitted from electric and hybrid electric vehicles propelled by an internal traction battery (see 3.2 and 3.3) when operated on the road.
This document applies to vehicles that have a traction battery voltage between 100 V and 1 000 V.
Electric vehicles to which CISPR 14-1 applies are not in the scope of this document.
This document applies only to road vehicles where an electric propulsion is used for sustained speed of more than 6 km/h.
Vehicles where the electric motor is only used to start up the internal combustion engine (e.g. “micro hybrid”) and vehicles where the electric motor is used for additional propulsion only during acceleration (e.g. “48 V mild hybrid vehicles”) are not in the scope of this document.
The radiated emission requirements in this document are not applicable to the intentional transmissions from a radio transmitter as defined by the ITU including their spurious emissions.
Annex C lists work being considered for future revisions.
