[0002] Fuel cells, especially proton exchange membrane fuel cells (PEMFCs), have been widely used in applications such as fuel cell electric vehicles and fuel cell backup power supplies due to their advantages of being pollution-free, having high specific energy, low noise, and high energy conversion efficiency.

[0003] In practical applications, voltage detectors are typically used to detect the voltage of each individual cell in a fuel cell stack to determine the voltage state of each cell. Therefore, the accuracy of the voltage detector's detection results is crucial, and it is necessary to test the voltage detector to ensure that the accuracy of its detection results meets the requirements.

[0004] Patent CN202321502922.3 discloses a detection system for a fuel cell voltage monitoring device. This system uses a AA battery as a voltage unit and a potentiometer as a voltage adjustment unit to simulate the individual cells in a fuel cell stack and perform voltage monitoring. Further research by the inventors revealed that, since voltage monitors are typically connected and tested via connectors in the casing, the disclosed detection system suffers from difficulty in aligning these connectors, resulting in low detection efficiency.

Detailed Implementation

[0027] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0029] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0030] As mentioned earlier, since voltage detectors are usually wired and tested through the wiring ports in the housing, the detection system disclosed in the current patent has difficulty aligning the wiring ports, resulting in low detection efficiency.

[0031] In view of this, embodiments of this application provide a testing system for a fuel cell voltage detector, which can be used to solve the problems in the prior art and can be combined with the present application. Figures 1-3The structure of the testing system is described in detail below. The testing system may include a main housing 1, a boss 2, a voltage detector mounting box clamp 3, and a test harness connector 4. The boss 2 is located on the surface of the main housing 1. The test harness connector 4 is located within the boss 2, near the side of the voltage detector mounting box clamp 3. The voltage detector mounting box clamp 3 is also located within the surface of the main housing 1, near the boss 2. This facilitates the connection of the voltage detector in the voltage detector mounting box clamp 3 to the test harness connector 4 on the side of the boss 2, thereby facilitating the testing of the voltage detector.

[0032] The voltage detector mounting box clamp 3 can be used to fix the voltage detector to be tested, so that the voltage detector to be tested can be connected to the test harness connector 4 on the side of the boss 2 by fixing the voltage detector to be tested in the mounting box clamp 3.

[0033] Regarding the method of fixing the voltage detector in the mounting box clamp 3, in practical applications, a groove 31 can be provided in the mounting box clamp 3 to place the voltage detector in the groove 31, thereby securing the voltage detector in place. Alternatively, the mounting box clamp 3 can also be provided with a detector positioning notch 32 for more accurate positioning of the voltage detector.

[0034] It should be noted that, considering that voltage detectors come in various specifications, the size of their housings and the types of their interfaces may differ. In this application, the voltage detector is secured by the groove 31 in the detector mounting box fixture. In order for the test system to be used to test various voltage detectors of different specifications, the detector mounting box fixture 3 is detachably mounted on the surface of the main housing 1. This allows for the adaptation to different specifications of voltage detectors by disassembling and replacing different detector mounting box fixtures 3.

[0035] In addition, the interface lengths of voltage inspectors of different specifications may also be different. In this case, the distance between the inspector mounting box clamp 3 and the test harness connector 4 needs to be adjustable. Therefore, a 1 can be set on the surface of the main housing 1, and the inspector mounting box clamp 3 can be set on the sliding guide rail 5. Of course, the sliding guide rail 5 can be perpendicular (including basically perpendicular) to the boss 2, and the side of the test harness connector 4 is provided. Thus, the distance between the inspector mounting box clamp 3 and the test harness connector 4 can be adjusted by sliding the inspector mounting box clamp 3 on the sliding guide rail 5.

[0036] Of course, in order to accommodate the sliding guide rail 5, a structure matching the sliding guide rail 5 can be set at the bottom of the inspection device mounting box clamp 3, so as to facilitate the sliding of the inspection device mounting box clamp 3 on the sliding guide rail 5.

[0037] In addition, to facilitate timely display of test results, the testing system may also include an all-in-one computer monitor 6 for displaying test results, allowing the test results to be displayed promptly during the testing process. The all-in-one computer monitor 6 can be fixed to the surface of the main housing 1 via a support bracket 61.

[0038] The main housing 1 may also be provided with a side wall slope 11, which can be located on the side wall of the front of the main housing 1. Multiple test control buttons 7 can be provided on this side wall slope 11. These test control buttons 7 may include, for example, a test start button, a test stop button, a device power button, a voltage data display button, and a rotary knob, allowing the test process to be controlled via these buttons 7. The rear of the main housing 1 may also be provided with a power interface 12, through which a power source can be connected to provide power for the operation of the test system.

[0039] The testing system for a fuel cell voltage detector provided in this application includes a main housing 1, a boss 2, a detector mounting box clamp 3, and a test wiring harness connector 4. The boss 2 is located on the surface of the main housing 1; the detector mounting box clamp 3 is located on the surface of the main housing 1, near the boss 2; and the test wiring harness connector 4 is located within the boss 2, near the side of the detector mounting box clamp 3. This allows the voltage detector to be tested to be placed in the detector mounting box clamp 3, and its wiring port to be connected to the test wiring harness connector 4 on the side of the boss 2, facilitating testing of the voltage detector and improving testing efficiency.

[0040] This utility model is not limited to the above-described embodiments. For those skilled in the art, various improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model. Contents not described in detail in this specification are prior art known to those skilled in the art.
