Intelligent optimization and monitoring device used for direct-current charger and direct-current charging system

Abstract

The invention discloses an intelligent optimization and monitoring device used for a direct-current charger and a direct-current charging system. According to a monitored battery charging request message BCL, needed power P0 of an electric car is calculated; a rounding function is adopted to round up to an integer, and the number N of charging sub modules currently required to be put into operation is obtained; a corresponding charging sub module input number message instruction is generated and sent to a charging controller; the current output efficiency eta is calculated; the N is adjusted,the current load rate lambda is calculated, when the current load rate lambda is within the preset range, the input number message instruction is generated, and is sent to the charging controller, andthe current output efficiency eta is calculated; N is continuously adjusted until when the N is adjusted up or down, lambda exceeds the preset range; and the maximum output efficiency eta max and theoptimal input number are output, and the optimal charging running state is executed. Optimization of the output efficiency of the direct-current charger can be achieved, and on the basis, the electric larceny analysis in the charging process can be achieved.

Description

technical field [0001] The invention relates to an intelligent real-time monitoring device for a charger, in particular to an intelligent optimization and monitoring device and a DC charging system for a DC charger. Background technique [0002] With the popularity of electric vehicles, electric vehicle charging facilities are also developing rapidly. Judging from the continuous release and update of national standards, industry standards and enterprise standards, the requirements and functions of electric vehicle charging facilities are gradually being improved and unified. Electric vehicles have gradually entered thousands of households, and charging facilities have gradually approached the majority of users. While good news continues to be announced, inappropriate events are also taking place. Charging an electric car for free? In 2018, a car-hailing driver in Beijing took advantage of a loophole in the charging software of the State Grid, and used the "pinch gun metho...

AI Technical Summary

Problems solved by technology

This intelligent anti-theft control device can facilitate the intelligent anti-theft of the battery pack, but in fact it does not give a specific technical solution for how to judge whether it is electricity theft, and does not fundamentally solve the problem of electricity theft in mainstream charging piles.
