[0002] As the core equipment of an energy storage system, the performance of the energy storage converter directly affects the system's energy conversion efficiency and operational reliability. During production testing, on-site commissioning, and after-sales maintenance, comprehensive testing is typically required on the DC side, grid side, power regulation capability, multi-condition response, protection actions, fault records, and key current and voltage waveforms. Existing testing methods mainly rely on manual operation, using external instruments such as oscilloscopes and electrical parameter analyzers to perform tests item by item. This is not only inefficient and costly, but also requires frequent wiring and disconnection, posing a risk of operational errors.

[0021] Based on the same inventive concept, this invention discloses a non-intrusive testing system for energy storage converters based on configuration panels, used to implement the energy storage converter testing method based on configuration panels described above. The system includes: An energy storage converter, which has an internal controller and a communication interface for communicating with external devices; The configuration panel has built-in test control logic and human-machine interface, and is connected to the communication interface of the energy storage converter via a communication cable. The configuration panel is configured to send control commands to the energy storage converter and receive, parse, and display operating data from the energy storage converter, thereby enabling non-intrusive testing of the energy storage converter.

[0022] In one embodiment, the configuration screen is a touch screen industrial computer that stores an executable test program, which includes instruction logic for controlling the energy storage converter and processing its returned data.

[0023] like Figure 2 As shown, it demonstrates the core structure, communication connection relationship and core functional logic of the non-intrusive testing system for energy storage converters based on the configuration panel. Specifically, it includes: the direct connection method between the energy storage converter (built-in controller and exposed communication interface) and the configuration panel (touch screen industrial computer), the closed-loop data flow of command issuance and data feedback between the two, and the integrated layout of core functional areas such as control commands, data display, fault recording, and automated testing on the configuration panel.

If automated testing is performed, the configuration panel will issue multi-condition commands according to the preset test sequence, automatically collect response data for each condition, process the data, and determine the test results according to preset rules, thus completing the non-intrusive testing and evaluation of the overall performance of the energy storage converter.
