As the number and variety of automotive electronic devices continue to increase, the electromagnetic environment within vehicles has become increasingly complex. At the same time, electronic devices and components on vehicles are highly
sensitive to electromagnetic interference, leading to instances of mutual interference among electronic components. During vehicle operation, if electromagnetic interference occurs, it can result in reduced performance of the affected devices in mild cases, or complete loss of functionality in severe cases, posing significant safety risks to drivers.
To assess the transient voltage disturbances and electromagnetic compatibility of automotive electronic devices, the International Organization for Standardization (ISO) has established the standard ISO 7637-2:2011 (Road vehicles - Electrical disturbances from conduction and coupling - Part 2: Electrical transient conduction along supply lines only). The ISO 16750-2 (Environmental conditions and testing for electrical and electronic equipment - Part 2: Electrical loads) standard has been split, resulting in more standardized test requirements.
With the continuous development and refinement of automotive manufacturing technology, and to better meet people's higher demands for the quality of automotive life, automakers are increasingly adopting electronic and electrical
systems in the research and development and manufacturing processes. As a result, the reliability of automotive electronic systems has become crucial for enhancing vehicle safety performance and efficiency. Therefore, the electromagnetic compatibility (EMC) characteristics of automotive electronics have become as important as the mechanical properties of vehicles. Consequently, EMC testing technology has become a significant component of the testing technology employed by international automotive manufacturers.
