Abstract

The invention discloses an operation state monitoring method and device of a charging module, equipment and a storage medium. The method comprises the following steps: acquiring complete machine operation parameters and transistor operation parameters of a plurality of first charging modules under different output voltages; determining the complete machine operation efficiency of each first charging module based on the complete machine operation parameters; determining a first operation state of each first charging module based on the transistor operation parameters; a running state monitoring model is obtained through fitting according to the multiple whole machine running efficiencies and the first running state; and the operation state monitoring model is adopted to determine a second operation state of a second charging module, and the second charging module is a charging module with an unknown operation state. The technical problems of low running state monitoring accuracy and low fault recognition rate of the running state monitoring method of the charging module in the prior art are solved.

Description

technical field [0001] The present invention relates to the technical field of fault detection, and in particular, to a method, device, device and storage medium for monitoring the running state of a charging module. Background technique [0002] In recent years, the number of electric vehicles has grown rapidly around the world, and related supporting facilities, mainly charging piles, have been continuously developed and improved. The number of charging piles in cities is increasing, which puts forward higher requirements for the reliability and safety of electric vehicle charging piles. As the core component of the charging pile, the charging module has a complex structure and variable operating conditions. Its operating status is difficult to accurately monitor and cannot guide the operation and maintenance work. There is an urgent need to develop charging module operating status monitoring technology to realize pre-fault prediction of charging equipment during actual op...
