Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual testing is used to test charging devices, then testing can be performed with simple equipment, but the testing process is cumbersome, time-consuming and laborious
Solution Approach 1:
The test board automatically executes test commands and collects test results without requiring manual intervention. The control module on the test board receives commands from the upper computer, automatically controls the charging device under test, and collects test data, enabling the system to serve itself and eliminate manual testing operations.
Solution Approach 2:
The patent replaces manual mechanical testing operations with an automated electronic control system. The upper computer sends digital commands through communication modules to control the charging device, and electronic sensors automatically collect test data, substituting the mechanical manual testing process with an automated electro-mechanical system.
2Loss of time
If manual testing is used, then equipment complexity is low, but the time required to complete tests is long
Solution Approach 1:
The test board pre-configures multiple test items and parameters before actual testing. The upper computer can prepare test sequences and command sets in advance, and the test board stores test configurations, enabling rapid execution of comprehensive tests without manual setup for each test item.
Solution Approach 2:
The automated test system continuously executes test commands and collects data without interruption. The control module maintains continuous communication with the charging device under test, continuously monitoring parameters and executing test sequences, eliminating the gaps and delays inherent in manual testing operations.

AI summary
Embodiments of the present disclosure provide a test system, a test method, and a test board for a charging device. The test board includes: a connecting circuit, configured to be connected to a charging device and a load module respectively, to form a test loop between the charging device and the load module through the connecting circuit; a first communication module, configured to communicate with an upper computer; a second communication module, configured to communicate with the charging device; and a control module, connected to the first communication module and the second communication module respectively, and configured to receive command information sent by the upper computer through the first communication module, and generate a test command according to the command information, to cause the test board or the charging device to execute the test command. Thereby, an automatic test can be realized, which is easy to operate, labor-saving and time-saving, and a duration of completing a full set of tests is shortened.
