Abstract

The invention provides an intelligent detection method for electric vehicle charging control, comprising the following steps: A. An information acquisition sub-module collects information from a front-end charging terminal to form a data stream record, and collects information at intervals during the entire charging process; B. Background modeling analysis to form a background analysis model; C. The access control sub-module sends control instruction information to the front-end charging terminal according to the preset charging mode value obtained by the background analysis model; D. The intelligent charging control detection module is based on real-time collected data Stream records, use the method of incremental classification decision tree to build a decision tree classification model; E. Compare the local analysis model and the background analysis model; F. Transfer the comparison result of step E to the background analysis system software, and refer to the local analysis model for pre-judgment Categorize target values โ€‹โ€‹and optimize back-end analysis models. While the present invention achieves the local high-efficiency detection function, the background system can continuously adjust and optimize the background analysis model according to the received results.

Description

technical field

[0001] The invention relates to an intelligent detection method for electric vehicle charging control. Background technique

[0002] The development of new energy vehicles is one of the main means for countries all over the world to deal with the energy crisis and environmental protection. With the rapid improvement of the service life and energy density of lithium-ion power batteries, various types of new energy vehicles have gradually entered the large-scale In the demonstration application stage, certain types of new energy vehicles have entered the commercialization stage.

[0003] At present, the domestic electric vehicle replacement station has developed from the stage of technical verification of the initial Olympic Games and World Expo to the stage of commercial promotion and operation with a certain scale. During this development process, relevant core charging equipment, replacement equipment, and monitoring system software and hardware have been in...
