This article presents the importance of defining product case and load simulator grounding in an automotive EMC test plan.
Electric vehicle batteries may have as much as 80% usable capacity when they are no longer suitable for powering motor vehicles. This article explores the post automotive options for these components, and discusses important considerations regarding their use.
India has several mandatory product certifications that affect automotive products. Most relevant are the AIS certification for automotive components, the BIS certification for electronic products and the WPC registration for wireless products.
The latest announcement by Chinese Certification Authority CNCA has a significant impact on many automotive suppliers and car manufacturers. Several products were removed from the list of products that require compulsory product certification. Other products must now obtain a CCC Self-Declaration.
Chinese Certification Authorities to Announce Important Changes in the CCC Certification Scheme for Automotive Components In 2002, China established the China Compulsory Certification system (CCC), which repre... Read More...
Imagine for a moment that you are trying out a brand new car: you slide into one of the ergonomic seats, start the engine and, to make things perfect, would like to listen to some music. However when you switch this on, you suddenly notice interesting side effects. The light comes on in the passenger compartment, for example. Or the radio starts whistling and whimpering.
The automotive industry has changed drastically in recent years. Advancements in technology paired with tighter federal fuel and emissions regulations have resulted in the need to place more electrical systems into vehicles. This in turn places a greater emphasis on keeping the Electromagnetic Interference (EMI) of these systems from interfering with each other through radiated and conducted emissions, as well as crosstalk between the multitudes of on-board systems.
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.
