The application, which relates to the technical field of circuit control, provides a relay control system and a relay control system of an electric automobile, thereby solving the technical problem that the use safety degree is low under the condition that many high-voltage components exist. The relay control system comprises an analog-to-digital converter for collecting the output voltage of power supply equipment, a first switching circuit, and a second switching circuit. The first switching circuit respectively connected with the analog-to-digital converter and the power supply equipment isused for determining the abnormal condition of the output voltage according to the voltage difference between the local voltage and the output voltage of the power supply equipment; and the second switching circuit s respectively connected with the first switching circuit and the relay is used for controlling the operation state of the relay according to the abnormal condition.
