A detection system and vehicle for high-voltage busbars

Abstract

This application provides a high-voltage busbar detection system and vehicle, applied in the field of voltage detection. The detection system includes first and second sampling circuits and a controller. The first sampling circuit is connected to the positive and negative terminals of the high-voltage busbar and a first power supply module, and outputs a first sampling signal. The second sampling circuit is connected to the positive and negative terminals of the high-voltage busbar and a second power supply module, and outputs a second sampling signal. The controller's first and second ports are connected to the first and second sampling circuits to receive the first and second sampling signals. The controller determines the voltage of the high-voltage busbar based on either the first or second sampling signal. The first and second sampling circuits in this system employ a redundancy mechanism. If one sampling circuit fails, the system can switch to the other, avoiding system crashes due to a single point of failure, thus ensuring the continuity and reliability of the system's detection.
