Description

Technical Field

[0001] The utility model relates to the technical field of energy storage products, in particular to a tooling for testing an energy storage monitoring module. Background Art

[0002] At present, with the rise of the new energy industry, more stable requirements are put forward for the power grid, and at the same time, more stringent requirements are also put forward for the equipment in the new energy industry. Therefore, the characteristics of peak shaving, valley filling and frequency modulation of energy storage products are becoming more and more popular. At the same time, the State Grid is also promoting the technological development of the energy storage industry to make more contributions to the stability of the power grid.

[0003] In the energy storage industry, an energy storage monitoring module is used to monitor the operating state of an energy storage product. The operating performance of the energy storage monitoring module needs to be tested to test whether the energy storage monitoring module can operate stably under various conditions and to test the monitoring efficiency of the energy storage monitoring module when the energy storage product generates fault parameters. At present, for the energy storage monitoring module, physical energy storage products are mostly used for testing to debug the defects of the energy storage monitoring module and verify the correctness of the energy storage monitoring module. However, the physical testing is restricted more. During the testing process, large-power devices such as a real battery management system and an AC-DC conversion system are actually operated, and the generated operating parameters are transmitted to the energy storage monitoring module. If incorrect parameters appear during the equipment debugging or the protection parameters are set unreasonably during the debugging process, in extreme cases, electrical accidents are likely to occur, and devices such as the battery management system and the AC-DC conversion system are easily damaged. Due to the need for continuous periodic testing, a certain proportion of the usage times of devices such as the battery management system and the AC-DC conversion system will be consumed, affecting the service life of each device, and the cost required for physical testing is also relatively high.

[0033] The tooling for testing the energy storage monitoring module of the present utility model has a lower cost. Since simulation devices are used, the cost is much lower than that of physical devices. Since simulation devices are used, extreme parameters that cannot be given by physical objects can be simulated, which can better test the defects of the energy storage monitoring module.

[0038] Specifically, in an alternative embodiment, the power supply module is connected to an external power grid through a main circuit breaker, and the power supply module outputs 24V voltage for supplying power to the energy storage monitoring module, the battery management system simulation device, the AC / DC conversion system simulation device, the 485 IO interface module, and the switch. In this tooling, the voltage required by each device is relatively low, and less electrical danger is generated. Since actual power devices such as the battery management system and the AC / DC conversion system are not used, the occurrence of electrical accidents is reduced, accidents such as damage to power devices will not occur, and electric shock accidents are not likely to occur.

[0039] Specifically, in an optional embodiment, it includes a control box, and the control box includes a box body and a box door. The battery management system simulation device, the AC-DC conversion system simulation device, the power supply module, the 485 IO interface module, and the switch are installed inside the box body. Multiple devices are integrally installed in the control box, occupying less space and having high flexibility, and can be not restricted by the test location.
