High-voltage loop fault positioning method and device, electric vehicle and storage medium

Abstract

The invention discloses a high-voltage loop fault positioning method and device of an electric automobile, the electric automobile and a storage medium, and the method comprises the steps: collecting the actual current of a plurality of sampling points on a high-voltage loop of the electric automobile; judging whether the actual current is smaller than a preset current, and determining the fault position of the high-voltage loop according to at least one sampling point smaller than the preset current; and generating a fault position code of the high-voltage loop according to the fault position so as to identify the fault position by using the fault position code during fault maintenance of the high-voltage loop. Therefore, the problems that in the prior art, since maintenance personnel need to troubleshoot and locate the fault positions of the high-voltage loop one by one, the fault position cannot be rapidly and accurately located, the maintenance efficiency is low, and the maintenance cost is increased are solved.

Description

technical field [0001] The present application relates to the technical field of new energy vehicles, in particular to a high-voltage circuit fault location method and device, an electric vehicle and a storage medium. Background technique [0002] With the continuous development of electric vehicles, there are more and more high-voltage accessories on the vehicle, resulting in a higher degree of integration of high-voltage boxes, and at the same time, the corresponding high-voltage circuits are becoming more and more complex. [0003] In related technologies, when a high-voltage circuit fault occurs in an electric vehicle, maintenance personnel are usually required to check and locate the fault location one by one. However, the complex high-voltage circuit greatly increases the difficulty of troubleshooting, making maintenance personnel often unable to quickly and accurately locate the fault location, reducing maintenance efficiency and increasing maintenance costs.
