From ICE to BEV: changing testing for passenger comfort

The shift from ICE to BEV development alters design and testing priorities. In the past, mileage and emissions were crucial, but now, battery power and noise take precedence. EMC testing becomes critical due to electronic elements emitting high-frequency radiation that may interfere with adjacent machines and systems. With BEVs removing engine and transmission noise, NVH testing now concentrates on interior component buzz, squeak, and rattle.
