And a module with power supply, charging, grounding and fault judging functions is arranged between the socket and the AC gun plug.

The testing method of the testing platform of the portable charger product for the vehicle comprises the following steps:

(1) placing a workpiece: the workpiece is placed on the automatic test board, the three plugs are inserted into the plug board hole sites, the alternating current gun plugs are inserted into the alternating current gun socket holes, and the equipment power supply is sequentially started.

(2) Starting a test: sweep a yard start test function test, equipment operation pilot lamp is bright.

(3) In the test: and observing whether the test item on the industrial control computer reports Fail to automatically stop testing.

(4) And (3) completing the test: and (5) after the equipment operation indicator lamp is turned off, the product is taken down after the test is finished, and the dustproof cover is arranged on the turnover frame.

The specific use method of the invention is as follows: the portable charger is placed on the test platform, a charging gun of the portable charger is connected to the charging interface, and after the three plugs of the product are inserted into the socket, whether the interfaces are inserted in place or not is checked. Turning on a main power switch and a computer test software self-checking device module to judge whether the device module works abnormally, turning on an activation test item, scanning codes to start an automatic test, finishing the test to generate records and relevant data of products, alarming when the device failure of the products is changed into a red light buzzer long sound, taking down defective products through analysis, and re-testing after finishing a defective product disposal flow.

The platform has the advantages of powerful functions, high automation degree, stable product performance through comprehensive test, reduced repair rate after delivery, convenience in tracing by generating a test report, statistics of product quality and improvement of product performance. The degree of automation of the platform is high, so that the performance of the tested factory product is more stable.
