How to Mitigate EMI in Electric and ICE Vehicles (Download)

Read this article online.

Electric vehicles (EVs) are popping up more frequently these days on our highways. Internal-combustion-engine (ICE) vehicles still dominate the roads, but their days could be numbered as EVs are fast becoming vehicles of choice. Both vehicle types can expect interference in their operation as time goes on because of growing external and internal electromagnetic interference (EMI).

Let’s first look at ICE vehicles, which can experience problems with EMI. Such vehicles see a narrowband EMI from their starter motor, ignition system, as well as various switches in the vehicle that can all cause broadband EMI. Many electronic devices inside and outside the vehicle can cause narrowband EMI.
