Automotive EMC testing under dynamic driving conditions

Alban Hemery, AVL List GmbH

Abstract

Current electric drive units have a much higher electromagnetic interference capability than combustion engines, at a considerably higher frequency range.

The electromagnetic compatibility (EMC) is also strongly influenced by the operating point of the drive unit such as accelerating and breaking manoeuvres. In addition, modern vehicles face the challenge to integrate ADAS functions using sensitive electronics at RF frequencies which can be influenced by high-power electric components. 

In order to release safe vehicles on the market, the EMC of key electric vehicles components needs to be analysed in an environment emulating real driving conditions as found in the final electric vehicle on the road. 

This presentation will review the main factors influencing the EMC of the Electric powertrain and the possible solutions for a more realistic test scenario.
