Electric vehicle charging failure diagnosis method, system, equipment and medium

Abstract

The invention provides an electric vehicle charging failure diagnosis method, system and device and a medium, and the method comprises the steps: extracting charging segment data and vehicle charging alarm data of a continuous period of time, and static data of a corresponding vehicle, and endowing each charging segment with a unique number; charging segment distances are determined according to the charging segment data, the charging segment distances are clustered, public charging stations are determined, and a public charging station information table is constructed; fusing the vehicle charging alarm data, the charging fragment data and the static data, screening out charging fragment information occurring in a public charging station, and obtaining a corresponding charging failure factor; and according to the charging failure factor, constructing a public place charging failure diagnosis model, according to the public place charging failure diagnosis model, diagnosing whether the charging fragment fails to be charged, and outputting a charging failure reason. According to the invention, an enterprise can conveniently carry out corresponding improvement according to failure reasons, the product quality is improved, and the user experience is improved.

Description

Technical field [0001] The present invention relates to the field of electric vehicle technology, in particular to a diagnostic method, system, apparatus and medium for charging failure of an electric vehicle. Background [0002] The data shows that in November 2021, the ownership of new energy vehicles exceeded 6 million, and in only 11 months, its ownership increased by 2 million, and the follow-up was only 4 months, which increased by 1 million, which shows that the period of rapid growth of new energy vehicles has arrived. With the explosive growth of new energy vehicles, the charging demand of new energy vehicle users in public places will continue to increase rapidly. [0003] Due to the current public charging station running on the market, there are a large number of management chaos, pile mismatch and other issues, while the charging vehicle itself may also have charging failure problems, resulting in frequent electric vehicle charging failures, directly affecting the ex...

AI Technical Summary

Problems solved by technology

[0003] However, due to the large number of problems such as management confusion and mismatched vehicle piles in the public charging stations currently operating in the market, and charging vehicles themselves may also have charging failure problems, resulting in frequent occurrence of electric vehicle charging failures, which directly affect electric vehicle users. On the other hand, it will also cause problems such as disordered charging order and difficult management for charging stations.

However, there is currently no better method to fully diagnose and count charging failure events and analyze the causes of charging failures
