Abstract

The invention discloses an anti-electromagnetic interference system for an electric car compressor. A filter is connected to a high-voltage power supply wire harness of the compressor in series; useless or even harmful frequency components in a signal are filtered out; the interference to the compressor in the electrifying process of a direct-current bus of the compressor is removed; and in addition, grounding treatment is carried out on a compressor housing, so that the effects on the electric compressor caused by electromagnetic interference which propagates through space are effectively inhibited.

Description

Technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a compressor anti-electromagnetic interference system for electric vehicles. Background technique [0002] At this stage, in the summer, when the electric vehicle is running, the electromagnetic interference caused by the electric vehicle's DC bus shields the compressor control signal transmission, causing the compressor to sleep, which greatly affects the comfort of passengers in the summer car, and even the high temperature inside the car Bottled water and personal belongings of passengers in the car produce harmful substances that affect the health of passengers. Summary of the invention [0003] In view of the shortcomings of the current technology, the present invention provides an electric vehicle compressor anti-electromagnetic interference system. The filter makes the communication signal between the main control and the drive normal when the electric compressor is wo...
