Entire vehicle quiescent current control circuit and current control method thereof

Abstract

The invention relates to an entire vehicle quiescent current control circuit and a current controlling method thereof. During the design process of the entire vehicle circuit, long electrical power supplies, which affect the quiescent current, of various electrical appliances are integrated in a main circuit in which a main switch for easily operating the on and off is added. The entire vehicle quiescent current control circuit prevents the frequently-appeared phenomenon of power shortage in entire vehicle, and avoids that the entire vehicles cannot be started during the transportation process or when arriving at the destination.

Description

technical field [0001] The invention relates to a quiescent current control circuit, in particular to a novel quiescent current control circuit for automobiles, and also relates to a complete vehicle circuit and a complete vehicle quiescent current control method. Background technique [0002] With the increase of the functions of automobile electrical appliances, there are more and more factors that cause the quiescent current of the whole vehicle to become larger. The distance and time of the transportation and storage process for delivery to customers are getting longer and longer. Especially with the rapid expansion of the export volume of automobiles, and most of them adopt the cheap but long-term sea transportation method, the total time for the automobiles to be transported and stored is as long as more than one month, and it is very easy for the entire vehicle to lose power frequently, resulting in It cannot be started during transportation and when arriving at the ...

Problems solved by technology

Especially with the rapid expansion of the export volume of automobiles, and most of them adopt the cheap but long-term sea transportation method, the total time for the automobiles to be transported and stored is as long as more than one month, and it is very easy for the entire vehicle to lose power frequently, resulting in Unable to start during transport and upon arrival at destination

There are two main methods to solve the problem of power-deficiency starting: one is to require the electrical components of the vehicle to be designed with no quiescent current or the quiescent current is extremely small. This method has strict requirements on suppliers, high cost, difficult to achieve and difficult to control , the other is to use wires to connect to a good battery, charge the battery, or replace the battery when the battery loses power, all of which require a lot of labor and material storage costs
