EV batteries and battery packs are complex systems, requiring a comprehensive design and testing strategy to help ensure safe and efficient electrical power.
As they become more commonplace in today’s motor vehicles, advanced driver assist systems (ADAS) require a unique set of testing procedures that include repeatability of the trigger mechanism in a safe, controlled environment to accurately measure their effectiveness.
Designing an EMC Automotive Test chamber to meet the requirements of CISPR 25 and ISO 11452-2. Plus, radiation patterns from the typical test antennas and recommendations for performance improvement.
From the time when automotive vehicles were essentially mechanical with spark ignition the only electrical system, through the many decades that brought the development of electrical, electronic and computer controlled automotive systems, the need for and methods of automotive testing have evolved along with the vehicles. At one time, electrical testing was sufficient. But with the dawn of the digital computer era, compatibility became a major issue. Those pesky clocked systems are inherently noise producers and are also subject to immunity issues.
