[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0028] This utility model discloses a flow battery reliability testing device, with reference to... Figure 1 As shown, the flow battery reliability testing device includes a storage tank 100 and at least one test line 200. The storage tank 100 is used to hold the electrolyte of the flow battery. The storage tank 100 has an outlet 110 and a return port 120. One end of the test line 200 is connected to the outlet 110 and the other end is connected to the return port 120. The test line 200 is used for detachable connection with the component under test. The component under test includes a circulation pump 10, a control valve 20, a sensor 30, and a heater 40. It is understood that the flow battery reliability testing device includes a storage tank 100 and at least one test pipeline 200. During the reliability testing process, a circulation pump 10, a control valve 20, a sensor 30, and a heater 40 can be installed into the test pipeline 200 according to the testing needs. Multiple test components can be set on one test pipeline 200, and the number of each test component can be one or more. Furthermore, multiple test components of different models can be set on multiple test pipelines 200. In the actual testing process, the circulation pump 10 serves as both a test component for reliability testing and a driving device for the electrolyte, driving the electrolyte to circulate between the test pipeline 200 and the storage tank 100. This enables reliability testing of different components of the flow battery in the same environment, resulting in high testing efficiency and avoiding resource waste.
[0029] Optionally, the sensor 30 can be a temperature sensor or a pressure sensor, and the test pipeline 200 can be equipped with only a temperature sensor, only a pressure sensor, or both a temperature sensor and a pressure sensor.
[0030] refer to Figure 1 As shown, there are multiple test lines 200. The flow battery reliability testing device also includes an outlet manifold 300 and a return manifold 400. The outlet manifold 300 is connected to one end of each of the multiple test lines 200 and is connected to the outlet port 110. The return manifold 400 is connected to the other end of each of the multiple test lines 200 and is connected to the return port 120. It can be understood that compared to having the two ends of each of the multiple test lines 200 connected to the return port 120 and the outlet port 110 respectively, using the outlet manifold 300 and the return manifold 400 to connect the multiple test lines 200 in parallel simplifies the pipeline structure, facilitates connection, provides better sealing, and ensures that the multiple test lines 200 do not interfere with each other, which is beneficial for reliability testing and improves testing efficiency.
[0031] Optionally, a main switch valve (not shown in the figure) may be installed on the outlet main pipe 300 and / or return main pipe 400. It is understood that in actual testing, after the test is completed, the component under test needs to be removed from the test pipeline 200. By setting the switch valve, the electrolyte flow can be cut off, thus effectively preventing the storage tank 100 from continuing to output electrolyte during the removal of the component under test. This helps to save electrolyte and reduce the testing cost of reliability testing.
[0032] refer to Figure 1 As shown, each test pipeline 200 includes a first connecting pipeline 210, a second connecting pipeline 220, and a third connecting pipeline 230. One end of the first connecting pipeline 210 is connected to the outlet 110, and the other end is detachably connected to the inlet of the circulation pump 10. One end of the second connecting pipeline 220 is connected to the outlet of the circulation pump 10, and the other end is connected to the heating inlet of the heater 40. One end of the third connecting pipeline 230 is connected to the heating outlet of the heater 40, and the other end is connected to the return port 120. It can be understood that by dividing the test pipeline 200 into three sections, in actual testing, if any one of the circulation pump 10, heater 40, control valve 20, or sensor 30 needs to be replaced, only the corresponding pipeline needs to be operated, without disconnecting the entire test pipeline 200. This modular test pipeline 200 can be spliced according to actual needs, thereby meeting different reliability testing requirements.
[0033] Optionally, a first switching valve (not shown) is provided on the first connecting pipe 210, which is located upstream of the inlet of the circulating pump 10. Two second switching valves (not shown) are provided on the second connecting pipe 220, and the control valve 20 and the sensor 30 are installed between the two second switching valves. A third switching valve (not shown) is provided on the third connecting pipe 230, which is located upstream of the heating inlet of the heater 40. Understandably, when it is necessary to replace the circulating pump 10, simply closing the first switch valve can cut off the flow of electrolyte from the storage tank 100 into the circulating pump 10, facilitating the replacement of the circulating pump 10 while avoiding electrolyte waste; when it is necessary to replace the control valve 20 and the sensor 30, simply closing the second switch valve can cut off the flow of electrolyte from the circulating pump 10 into the second connecting pipe 220, facilitating the replacement of the control valve 20 and the sensor 30 while avoiding electrolyte waste; when it is necessary to replace the heater 40, simply closing the third switch valve can cut off the flow of electrolyte from the second connecting pipe 220 into the heater 40, facilitating the replacement of the circulating pump 10 while avoiding electrolyte waste.
[0034] It should be noted that, in the embodiments of this utility model, the first switching valve, the second switching valve, and the third switching valve can be manual valves or solenoid valves, and the specific choice can be made according to actual needs.
[0035] Optionally, the second connecting pipe 220 is provided with multiple mounting points for mounting at least one of the control valve 20 and the sensor 30. It is understood that providing mounting points on the second connecting pipe 220 facilitates the installation of the control valve 20 and the sensor 30, thereby simplifying the reliability testing process.
[0036] Optionally, both ends of the first connecting pipe 210, the second connecting pipe 220, and the third connecting pipe 230 are provided with sealed pipe joints (not shown in the figure). It can be understood that providing sealed pipe joints at both ends of the first connecting pipe 210, the second connecting pipe 220, and the third connecting pipe 230 can ensure the sealing of the entire electrolyte flow circuit during actual testing and prevent electrolyte leakage.
[0037] Optionally, the flow battery reliability testing apparatus also includes a test bench 500 (not shown in the figure), with the liquid storage tank 100 fixed to the test bench 500 and the test tubing 200 laid on the test bench 500. It is understood that mounting both the liquid storage tank 100 and the test tubing 200 on the test bench 500 can improve stability and prevent the liquid storage tank 100 or the test tubing 200 from shaking during reliability testing, thus avoiding any impact on the test results.
[0038] Optionally, the storage tank 100 is provided with a mounting portion 130, and the mounting member 600 passes through the mounting portion 130 and connects to the test stand 500 to fix the storage tank 100 on the test stand 500. It is understood that fixing the storage tank 100 to the test stand 500 by the mounting member 600 can, on the one hand, secure the storage tank 100, and on the other hand, improve the stability of the storage tank 100, preventing the storage tank 100 from shaking during reliability testing, thus avoiding any impact on the test results.
[0039] Alternatively, the mounting component 600 includes a connecting bolt and a connecting nut. The connecting bolt passes through the mounting part 130 and the stand 500 and engages with the connecting nut. Understandably, during actual installation, after the liquid storage tank 100 is mounted on the stand 500, the mounting part 130 is aligned with the installation position. The connecting bolt is then inserted into the mounting part 130 and the stand 500, and the connecting nut is screwed into the connecting bolt to lock it in place. This connection method not only secures the liquid storage tank 100 but also improves its stability, preventing the liquid storage tank 100 from shaking during reliability testing, which could affect the test results.
