Embodiment Construction

[0058] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0059] The preferred embodiment automobile electrical performance testing method comprises the following steps:

[0060] Step A. Static current test of vehicle electrical components

[0061] The static current test of the whole vehicle is used to verify the parasitic current of each electrical appliance when the whole vehicle is at rest and each electrical appliance has entered a dormant state. To avoid excessive parasitic current, the battery will be fed after the car is parked for a "long" time. Therefore, the quiescent current of the whole vehicle should not exceed 20mA, and a single consumer should not exceed 3mA.

[0062] Measurement method:

[0063] A1. Turn off all electrical switches, doors and trunk lids, unplug the ignition key, and only open the front hatch for the next step.

[0064] A2, such as figure 1 As shown, adjust...

Abstract

The invention belongs to the technical field of automobile electronic equipment, particularly relates to an automobile electric performance testing method and system, and solves the problem that existing automobile circuit detection is not comprehensive enough and the like. The automobile electric performance testing method comprises the following steps: A, whole automobile electric device staticcurrent test; B, whole automobile load test; C, whole automobile voltage reduction test; and D, whole automobile wire overload short-circuit test. The automobile electric performance testing method and system have the advantages that whole automobile electrical loop protection conditions and grounding performance are tested and verified in an emphasized manner, concealed shortcomings in power distribution, grounding distribution, loop protection and the like in whole automobile design are analyzed according to test data, electrical performance of a whole automobile is optimized and improved, the performance and reliability of the electrical system of the whole automobile are improved to avoid the concealed shortcomings according to the concealed electrical performance shortcomings in the whole automobile design, thus, unreasonable circumstances such as too thick selected wires and excessive protection design are avoided, and lightweight and economical and reasonable design are achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile electronic equipment, and in particular relates to a method and system for testing electric performance of automobiles. Background technique [0002] With the improvement of people's living standards and the rapid development of the automobile industry, people's requirements for comfort, safety and economy have increased, and the configuration of automobiles has become more and more abundant. More and more electronic and electrical equipment or systems are integrated with the entire vehicle. Inside. In the design and development process of the vehicle, the requirements for the performance, reliability, light weight and cost control of the electrical circuit system of the vehicle are also higher. Therefore, the test and verification of the matching rationality of the electronic and electrical system of the whole vehicle has become an important link in the development of the whole vehicle. In t...
