A method for power coordination control of independent two guns of a charging pile

Abstract

The invention provides a method for power coordination control of independent two guns of a charging pile. The method comprises: when power parallel charging is not required, cutting off communicationbetween two charging gun control modules, cutting off a first circuit breaker group, selecting a charging gun to be charged through a second circuit breaker group, and controlling a corresponding charging gun to be charged by the charging gun control module; when parallel charging of power is needed, selecting the charging gun to be charged through the second circuit breaker group, broadcasting own running states or running parameters of the two charging gun control modules broadcast, and receiving and analyzing the running states or running parameters sent by the other party by the two charging gun control modules. According to the analyzed operation state or operation parameters, switching the first circuit breaker group to a charging gun to be charged in parallel with power, and controlling the charging guns corresponding to the two charging gun control modules to perform charging. The method has the advantages that the parallel charging of the power can be carried out according tothe actual needs, the charging efficiency is improved, and the waiting time for charging by the customer is reduced.

Description

technical field [0001] The invention relates to the field of new energy vehicle charging, in particular to a method for coordinated control of the power of two charging pile independent guns. Background technique [0002] At present, most charging piles have two independent charging guns, and the power distributed by the two charging guns is equal. Since most of the two charging guns are not used at the same time during actual use, the power of the other charging gun is wasted when one of the charging guns is used; During the charging process of the car, it is hoped that the battery can be fully charged as soon as possible to reduce the waiting time, but it is impossible to achieve fast charging with an independent charging gun. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for coordinating the power of the independent dual guns of the charging pile. Through this control method, the battery of the ele...
