EMC (Electro Magnetic Compatibility) Testing

EMC testing is a comprehensive assessment of electromagnetic interference (EMI) and electromagnetic susceptibility (EMS) of electronic products, which is one of the important indicators for evaluating the quality of electronic products. New energy vehicles use electric drive systems to drive vehicles. During the charging and discharging process of the vehicle, the action of high-power semiconductor switching devices will cause sudden changes in high voltage and large current, thereby emitting strong electromagnetic interference. If the electromagnetic radiation is too large, it may cause functional failure or malfunction of electronic equipment, and even burn or breakdown components, seriously affecting the safe driving of the vehicle. Therefore, it is very necessary to conduct EMC testing on vehicles.

Most vehicle EMC performance problems originate from component-level electromagnetic compatibility issues. EMC testing is conducted in accordance with relevant international industry standards and regulations. It is an important means to evaluate the EMC performance of complete vehicles and parts, and can provide data guidance and technical support to EMC designers.

STEMart provides comprehensive EMC testing services to ensure that vehicles or components can function properly in the electromagnetic environment in which they work and avoid electromagnetic interference to other components, thereby improving the reliability and safety of vehicles.
