With the continuous development of automotive electronics technology, EMC testing for automotive electronics is becoming increasingly important. Then what is EMC testing for automotive electronics?
EMC refers to the ability of equipment or systems to operate normally in its electromagnetic environment without causing unbearable electromagnetic interference to anything in that environment.
EMC includes two requirements
- EMI: refers to the electromagnetic interference generated by the environment in which the device is defined to not exceed a certain limit during normal operation, which is called electromagnetic interference, short for EMI.
- EMS: refers to the equipment having a certain degree of immunity to electromagnetic interference present in the environment, which is called electromagnetic susceptibility, short for EMS.
For automotive electronics, it is necessary to limit external interference from vehicles, protect onboard radio equipment and other sensitive devices, and strictly require the electromagnetic immunity of vehicles to ensure their normal operation in harsh electromagnetic environments. Through EMI and EMS testing, it can be ensured that the electronic components inside the vehicle can operate stably in various environments without interference or causing problems to the surrounding environment.
Automotive electronics EMC testing includes the following items:
1. Electromagnetic radiation interference testing: Test and radiation interference limits for vehicles and components are tested to protect broadcasting equipment used in the surrounding environment from being affected.
2. Transient interference test of power lines conduction: The 12V/24V equipment system installed on the vehicle generates noise at the instant of switching, and conducts transient interference testing according to the established limit value to protect the vehicle performance and safety.
3. Transient withstand test of power line conduction: The transient withstand test of 12V/24V equipment system installed on the vehicle, and test according to the established limit values to ensure the performance and safety of the equipment system in vehicle use.
4. Electromagnetic radiation withstand test: Confirm the immunity of various control devices on the vehicle and its components to performance degradation caused by radiated electromagnetic waves under usage conditions, to improve the performance and safety of the tram.
5. ESD (electrostatic discharge) test: Test the immunity of the entire vehicle and the 12V/24V equipment system installed on the vehicle to electrostatic discharge to ensure safety during use.
These tests must be conducted strictly in accordance with certain standards and regulations. During the testing process, compatibility with relevant equipment should be ensured, and there should be no adverse effects on the surrounding environment and other equipment.
