Test system for vehicle quiescent current

Abstract

The invention discloses a test system for vehicle quiescent current, comprising a vehicle electric power source arranged in a vehicle to be tested; a controlled unit and a standard resistor formed by vehicle electric load and connected with a loop in series; a control unit arranged outside the vehicle to be tested for controlling the opening and closing of the controlled unit; a data acquisition module arranged outside the vehicle to be tested for acquiring voltage of the standard resistor at two terminals; a data conversion module arranged outside the vehicle to be tested for converting the data collected by the data acquisition module to electric current. Therefore, the long time and continuous test for the vehicle voltage can be realized, the voltage of the vehicle tested by the test can accord with requirement; the disadvantage of successful starting with difficulty can be avoided, after long time lying idle of the vehicle; the subsequent quality complaint can be avoided.

Description

technical field [0001] The invention relates to a current testing system, in particular to a vehicle static current testing system. Background technique [0002] In recent years, with the development of the automobile industry, various types of cars have been developed in my country to meet the needs of different groups of people. In order to ensure the quality of the car, the manufacturer must conduct various tests on the car before leaving the factory, including testing the power supply of the car, so as to prevent after-sales complaints caused by the car’s design power shortage and difficulty in supporting long-term storage. However, in the existing test method for the current provided by the power supply, testers use a multimeter to test. Because it is a live operation, the manual technical requirements for the testers are very high, and a little carelessness may easily lead to the occurrence of electric shock hazards. Moreover, this kind of test is only a point test, ...

And the existing test method of the electric current provided by the power supply is to use the multimeter to test by the tester

Because it is a live operation, the manual technical requirements of the testers are very high, and a little carelessness may easily lead to the occurrence of electric shock hazards.

Moreover, this kind of test is only a point test, and it is difficult to support the process test, especially the current in the long-term placement process of the car cannot be continuously tested, and naturally it is impossible to carry out long-term continuous testing of the car placed in the parking lot, which makes It is difficult for the manufacturer to accurately know the power support of the car in the parking lot environment (that is, when it is interfered by various radio unlocking signals for a long time)
