The invention relates to the field of electric vehicle control, provides an electromagnetic compatibility system of an all-in-one electric vehicle controller, and aims to solve the problem of signal coupling interference between high voltage and low voltage and between high voltage input and output caused by control function integration in the all-in-one electric vehicle controller. The system comprises a low-voltage filter circuit and a high-voltage filter circuit, and the low-voltage filter circuit is arranged in an interface unit and a control unit and is used for filtering low-voltage signals passing through the interface unit and the control unit; the high-voltage filter circuit is arranged in the driving unit and is used for filtering the high-voltage power supply passing through the driving unit; the low-voltage filter circuit comprises a filter arranged in the interface unit and is confirmed as an interface filter; the interface unit comprises at least one stage of interface filter, and at least one interface filter is a common-mode CLC type filter formed by combining a capacitor and an inductor. According to the invention, the electromagnetic compatibility of the all-in-one electric vehicle controller is realized, and the anti-interference capability is improved.
