Intelligent detection method for electric vehicle charging control

Abstract

The invention provides an intelligent detection method for electric vehicle charging control. The intelligent detection control method includes the following steps that A, an formation acquisition sub module acquires information from a front end charging terminal, then a data stream record is formed, and information is acquired every a period of time in the whole charging process; B, background modeling analysis is conducted, and then a background analysis model is formed; C, an access control sub module sends control instruction information to the front end charging terminal according to a preset charging mode value acquired by the background analysis model; D, an intelligent charging control detection module is based on the data stream record acquired in real time to construct a decision tree classification model through an increment classification decision tree method; E, a local analysis model and the background analysis model are compared; F, a comparison result acquired by the step E is transmitted to background analysis system software, a classification target value is prejudged with the reference to the local analysis model, and the background analysis model is optimized. According to the intelligent detection method, the local efficient detection function is achieved, and a background system can continuously adjust and optimize the background analysis model according to the received result.

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...

Problems solved by technology

[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 industrialized. From the perspective of equipment performance indicators, product technology and reliability, it can meet the needs of battery replacement and charging. From the actual situation of current promotion and application, one of the main problems is that the charging load of the battery replacement station is affected by the law of vehicle operation. Larger, and most electric vehicles have morning and evening peak periods and flat peak periods, so that the load of the substation shows large load fluctuations, and the peak load time is close to the peak period of othe
