Stan Dolecki, Sr. of Elite Electronic Engineering

Electric Vehicles (EVs) sales are projected to be nearly 5.6 million by 2030,  representing more than 32 percent of annual light-duty vehicle sales in 2030.  Nearly all car and truck manufacturers are transitioning from internal combustion  engine powertrains to full electric or hybrid systems with the goal of zero  or near-zero CO2 emissions.       At the heart of all EVs are advanced batteries and fuel cells as well as innovative power electronics. This new technology brings great opportunity for greenhouse gas reductions, but it also belies a wide range of engineering, testing, and manufacturing challenges. Because EVs rely on the inherent power switching of high voltages and currents, electromagnetic radio frequency emissions, and their unintended interference to onboard receivers becomes one of the key tasks that designers must address. In addition, electric powertrains must be robust and immune to radio frequency (RF) waves that couple onto vehicle harness and systems. On-vehicle transmitters and off-board generated RF energy can interact with vehicle controls and cause RF susceptibilities that manifest as serious safety and reliability problems.       This presentation will provide an overview of whole vehicle electromagnetic compatibility  (EMC) and the testing processes for EVs. We will outline the technical reasons  why EMC testing is necessary and the government regulatory requirements that apply.  The testing methods will be described with emphasis on the role and unique requirement for vehicle EMC testing on a chassis dynamometer .
