Abstract

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.

Description

technical field [0001] The invention relates to the technical field of circuit control, in particular to a relay control system and a relay control system of an electric vehicle. Background technique [0002] At present, the use of electric vehicles is becoming more and more widespread. The main components in electric vehicles include battery systems, motor systems, electronic control systems, etc., all of which are high-voltage components. [0003] In the electrical design process of electric vehicles, relays are widely used. For electric vehicles, the design of the relay control circuit is more important, and its design quality directly affects the safety and reliability of the vehicle. However, there are many high-voltage components in electric vehicles, and the circuit safety level is relatively low during the use of relays. Contents of the invention [0004] The object of the present invention is to provide a relay control system and an electric vehicle relay contr...
