[0046] The following is a detailed description of a semi-integrated energy storage container testing machine provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are listed as the best and preferred embodiments, and other alternative methods can also be used by technicians in some known technical fields; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0047] It should be noted that the references to "one embodiment", "embodiment", "exemplary embodiment", "some embodiments" and the like in the specification indicate that the embodiments described may include specific features, structures or characteristics, but not every embodiment may include the specific features, structures or characteristics. In addition, when a specific feature, structure or characteristic is described in conjunction with an embodiment, it should be within the knowledge of a person skilled in the art to implement such feature, structure or characteristic in conjunction with other embodiments (whether or not explicitly described).

[0048] In general, a term can be understood, at least in part, from its use in context. For example, depending, at least in part, on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in the singular sense, or can be used to describe a combination of features, structures, or characteristics in the plural sense. Additionally, the term "based on" can be understood as not necessarily intended to convey an exclusive set of factors, but can instead, depending, at least in part, on the context, allow for the presence of other factors that are not necessarily explicitly described.

[0049] It will be understood that the meaning of “on,” “over,” and “above” in this disclosure should be interpreted in the broadest manner, so that “on” not only means “directly on” something, but also includes the meaning of being “on” something with intervening features or layers therebetween, and “on” or “over” not only means “on” or “above” something, but also includes the meaning of being “on” or “above” something with no intervening features or layers therebetween.

[0050] Additionally, spatially relative terms such as "under," "beneath," "lower," "above," "upper," and the like may be used herein for descriptive convenience to describe the relationship of one element or feature to another element or features, as shown in the accompanying drawings. Spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the accompanying drawings. The device may be oriented in other ways, and the spatially relative descriptors used herein may be similarly interpreted accordingly.

[0051] like Figure 1-Figure 3 As shown, an embodiment of the present invention provides a semi-integrated energy storage container testing machine, comprising the following components:

[0052] A computer, which runs the test software, records and analyzes the data, and manages the various test equipment in a unified manner. Through the pre-written test program, the computer can send instructions to the downstream test instruments and control panels, and receive their feedback data. The computer can also realize real-time monitoring of the test process, data storage and processing, and generate test reports to ensure that the test steps of each project are carried out in an orderly manner;

[0053] The switch is used to realize high-speed network communication between the internal devices of the system. At the same time, the computer, various detection instruments and control modules can be connected to a unified network platform through wired communication, ensuring that data instructions can be transmitted quickly and stably between different devices; the existence of the switch enables multiple detection instruments to work online at the same time and receive control instructions, realizing multi-channel data acquisition and collaborative control.

[0054] Insulation withstand voltage tester, which is used to measure the insulation withstand voltage value of the high-voltage cable of the energy storage box, which is crucial for evaluating the electrical safety performance of the energy storage container; by applying a certain voltage to the high-voltage cable and measuring its leakage current and other parameters, it is determined whether the insulation withstand voltage value meets the standard;

[0055] Micro-resistance tester, the micro-resistance tester is used to measure the insulation grounding continuity of battery cluster racks and door handles and other parts. By accurately measuring the resistance value, it can be determined whether the grounding of these parts is good to avoid safety hazards such as leakage.

[0056] It should be further explained that this embodiment also includes a fire communication control board, which is used to realize the communication protocol conversion between the fire host and the computer;

[0057] Fire host, which is used to centrally process various fire signals and issue corresponding alarm and linkage commands; the fire host receives input signals from the box fire module (smoke, temperature, gas sensor signals or manual alarm trigger information), analyzes the fire characteristics, and the preset logic in the board will send linkage control instructions, output the results to the linkage control equipment (aerosol, exhaust fan and sound and light alarm, etc.), and transmit the information to the fire communication control board;

[0058] 24VDC backup power supply, which is used to provide continuous power for the detection system and key safety equipment when the main power supply is interrupted; the power supply is generally composed of a battery pack, which is charged and kept fully charged during normal operation. Once the external power supply is interrupted or the voltage is unstable, the backup power supply immediately takes over the power supply to ensure the continuous operation of key safety functions (such as fire protection systems and core control circuits) without interrupting safety protection and data recording;

[0059] 24VDC detection control board, which is used to distribute, stabilize and monitor multiple 24V DC power supplies and related signals; by real-time detection and adjustment of the voltage and current output by the 24V power supply, the control board can ensure that downstream equipment operates under stable voltage conditions, and promptly alarm or automatically adjust the working state when abnormal voltage fluctuates;

[0060] Transformer, the transformer is used for voltage conversion and isolation of AC power supply; by selecting a suitable transformation ratio, the transformer can convert the external grid voltage into a nominal voltage level that meets the system test requirements, while achieving electrical isolation between the system and the grid. The transformer can also provide working power of different voltage levels for certain test instruments or modules, ensuring that the entire detection system operates safely and stably while meeting technical requirements.

[0061] like Figure 4-Figure 8As shown, a method for using a semi-integrated energy storage container testing machine includes the following steps:

[0062] S1. Connect the insulation withstand voltage tester, microresistance tester, fire host, PLC and other equipment to the switch through network cables or other communication cables, and then connect the switch to the computer to ensure normal communication between the devices;

[0064] S3. Start the tester, and the computer initializes the parameter settings of each device, such as the test voltage range of the insulation withstand voltage tester, the measurement accuracy of the micro resistance tester, etc.

[0065] S4. The operator selects the test items to be performed or starts the automated test process through the computer operation interface;

[0066] S5. Each test device starts to collect data, such as the insulation withstand voltage tester performs insulation withstand voltage test on the high-voltage cable, the micro resistance tester measures the resistance of the battery cluster rack and the door handle, the fire host obtains the fire module data, and the PLC sends the internal status information, etc.;

[0067] S51, the insulation withstand voltage tester applies a test voltage to the high-voltage cable of the energy storage box, collects the insulation withstand voltage related data of the cable, such as leakage current, voltage drop, etc., and feeds these data back to the computer;

[0068] S52, micro resistance tester measures the resistance of battery cluster rack and door handle, etc., obtains the resistance value data of insulation ground continuity, and then sends the data to the computer;

[0069] S53, the fire host monitors the status of the fire module in real time, such as the feedback values ​​of the smoke sensor, temperature sensor, etc., and transmits these fire-related data to the computer;

[0070] S54, the PLC sends information such as the status of the travel switch in the energy storage container (such as the switch status of the door, the operating limit status of the equipment, etc.), the feedback value of the air conditioner (such as temperature, humidity, operating mode, etc.), the status of each switch (such as the on / off status of the circuit breaker, etc.) to the computer;

[0071] S6. The computer receives and processes the data, makes judgments according to the above test principles, and generates test results and reports;

[0072] S61, after receiving the data from each device, the computer processes it according to the preset standards and algorithms;

[0073] S62. For the insulation withstand voltage value, the computer compares the data fed back by the insulation withstand voltage instrument with the standard insulation withstand voltage value range. If the measured value is within the range, the insulation withstand voltage performance of the high-voltage cable is judged to be qualified; otherwise, it is judged to be unqualified;

[0074] S63. For the insulation withstand voltage value, the computer compares the data fed back by the insulation withstand voltage instrument with the standard insulation withstand voltage value range. If the measured value is within the range, the insulation withstand voltage performance of the high-voltage cable is judged to be qualified; otherwise, it is judged to be unqualified;

[0075] S64. In terms of the fire module feedback value, the computer determines whether there is a fire hazard based on the data sent by the fire host. For example, if the smoke sensor value exceeds the normal threshold or the temperature sensor value increases abnormally, the computer determines that there may be a risk in the fire protection system;

[0076] S65. With respect to PLC information such as the travel switch status, air conditioning feedback values, and the status of each switch, the computer makes judgments based on pre-set logical relationships. For example, if the travel switch shows that the door is not closed normally but should be in a closed state when the energy storage container is running, the computer determines that there is an abnormality. For the air conditioning feedback value, if the temperature is not within the set operating temperature range, the air conditioning is determined to be abnormal. For the switch status, if the circuit breaker should be closed but is actually in an open state, it is determined to be abnormal.

[0077] S7. The operator checks the test results and reports, handles the energy storage container accordingly based on the results, and repairs and adjusts unqualified items.

[0078] It should be further explained in this embodiment that the result report includes various test contents, measurement values, judgment results and suggested solutions for unqualified items. At the same time, the computer can also feed back the test results to the operator or related management system in an intuitive manner.

In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details.
