Understand the sources of electromagnetic interference in electric vehicles
Understanding the origins of electromagnetic interference (EMI) in electric vehicles (EVs) is crucial for addressing the challenges posed by electrical noise sources. EMI and electrostatic discharge (ESD) are the two main types of interference that can disrupt the operation of electronic circuits within vehicles. In the context of wirelessly connected vehicles, radiated noise, specifically radio frequency interference (RFI), becomes a significant aspect in identifying EMI sources.EMI is present in all types of vehicles, including older internal combustion engines and modern EVs. As the electronic content of cars increases, so does the potential for EMI sources and the number of vulnerable systems. To better understand potential EMI sources in an EV, it is essential to clarify key terminology and concepts.EMI refers to unwanted electromagnetic fields that can disrupt electronic circuits.
