New energy automobile equipotential test system and test method

Abstract

The invention provides a new energy automobile equipotential test system and test method. The equipotential test system comprises a detection probe, a grounding chuck and a control machine. The detection probe comprises a probe rod, a detection handle, a moving contact B, a moving contact A, a signal control line, a test current output line and a voltage signal input line. According to the equipotential test system for the new energy automobile, a probe mode is adopted for testing, the problem that some places of a chuck are inconvenient to clamp is solved, the probe is of a contact type, the test method is flexible and diverse, hardware configuration does not need to be changed when detection items are increased, the problem of field use of the equipotential test is thoroughly solved, the method is a new thought and a new method for thoroughly solving the problem, and the flexibility and the efficiency of the test are improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle detection, in particular to a new energy vehicle equipotential testing system and a testing method. Background technique [0002] The high-voltage safety of new energy vehicles has always been one of the sensitive topics of concern to production supervision departments and enterprises, and equipotential testing is an important step in the high-voltage safety of new energy vehicles. The current general detection method is to use a collet to clamp the test site for testing. The test steps are as follows: [0003] 1) Take the grounding chuck and the chucks of each component under test and clamp them to the corresponding positions; [0004] 2) After clamping, confirm again whether the chuck is falling off and loose; [0005] 3) Scan the material code / VIN number; [0006] 4) The equipment starts to test, and the tested points are tested one by one; [0007] 5) After the test is completed, ...

AI Technical Summary

Problems solved by technology

[0012] 1. The space in the cabin is small, the chuck is large, and it is not easy to operate. Some parts are installed in inconvenient places, making it difficult to clamp;

[0013] 2. Most of the components under test are large control modules with a square shape, and the clips cannot be clamped;

[0014] 3. When the clamping position is wrong or the clamping is not firm, the data error is very large;

[0015] 4. Due to the large size of the module, the clips are likely to fall off during the test, and the testers can only find out after the test is completed, which is inefficient, repeated operations, and waste of time;

[0016] 5. It cannot be tested repeatedly in a targeted and timely manner, and the data comparability is poor;

[0017] 6. There are too many test clips, it is troublesome to identify, the testers are easy to confuse the measured point due to negligence, and the data is confused;

[0018] 7. Due to too many test clips and wiring harnesses, on-site management is not easy
