From the perspective of vehicle electromagnetic compatibility, this is a potential source of strong electromagnetic interference. It is integrated and installed inside the vehicle, which may cause serious deterioration of the electromagnetic environment inside the vehicle, especially for the normal operation of low-voltage electrical and electronic equipment. .
New energy vehicles integrate more electronic systems, sensors and actuators to meet the needs of automation and intelligence.
Due to the change of power system and the mixed application of high and low voltage electronic devices, the control system has become a safety-critical system. The energy conversion mode of the hybrid system is closely related to its power drive, forming a unique multi-path coupling interference characteristic, which will bring more complex electromagnetic interference problems. With the wide application of high-voltage electric drive system, whether it is basic theory, system design or test standards need to be strengthened.
