D5.4  EMC measurements and testing methods for FEVs 

Executive Summary

This document is a public deliverable (D5.4) of the HEMIS project. It deals in detail with the gaps in the measurement standards, the steps being done to address the gaps by the standards bodies and also provides details of additional testing that can be carried out to fill the gaps detected and previously summarized in the deliverable D5.1. It should be noted that the only additional test equipment which is required are new Artificial Networks (AN) for testing high voltage DC networks, no other additional test equipment is required to be developed to fill these gaps (existing equipment is suitable) but rather the gaps relate to frequency ranges over which testing is carried out and the number of positions at which radiated fields are measured.

It should also be noted that some of the gaps in current standards (e.g. lack of height scanning in radiated emissions testing of vehicles) do not only relate to fully electric vehicles, but also to those with an internal combustion engine. As such a summary of the main points in D5.1 has been included in this document.

Measurement results obtained as part of the HEMIS project (see D5.2 and D5.5) show that high magnetic field can be measured close to the electric powertrain. The fields take the form of low frequency radiated emissions and are generally narrow band in nature. The fields fall off rapidly with distance, and the measured field depends greatly on the cable layout. Again, suitable test equipment (3 axis field probes) already exists although the limit levels may need updating.
