[0028] The specific implementation of the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the present invention, and is not used to limit the embodiment of the present invention.

[0029] Embodiment 1

[0030] Figure 1 Schematic diagram of the structure of the hydrogenation test device of the first embodiment of the present invention. Figure 1 As shown, the hydrogenation testing device includes a mobile platform 1 and a weight testing device 2, a sensor component 3 and a control device 4 arranged on the mobile platform 1.

[0031] Wherein, the mobile platform 1 is as follows Figure 1As shown, for example, it is a supporting platform that can be freely moved by wheels, but the embodiment of the present invention is not limited thereto. The mobile platform 1 can also be a box-structured platform, for example.

[0032] In the embodiment of the present invention, the weight test device 2, the sensor assembly 3 and the control device 4 can be fixedly arranged on the mobile platform 1 to form a movable integral test device, and when in use, the integral test device is moved to a suitable position for hydrogenation testing. However, in other embodiments, the weight test device 2, the sensor assembly 3 and the control device 4 can also be detachably arranged on the mobile platform 1, so that after the mobile platform 1 is moved to the hydrogenation site, the weight test device 2, the sensor assembly 3 and the control device 4 can be removed from the mobile platform 1 and installed at a suitable test position according to the actual needs of the site.

[0033] In this embodiment, the weight testing device 2 is installed in conjunction with the on-board hydrogen storage bottle to determine the mass of hydrogen added to the on-board hydrogen storage bottle. In a preferred embodiment, the weight testing device 2 may include at least two scales, and the at least two scales include at least one scale for a 35MPa on-board hydrogen storage bottle and at least one scale for a 70MPa on-board hydrogen storage bottle. Here, the most commonly used on-board hydrogen storage bottles are mainly 35MPa and 70MPa, so suitable scales are configured for them respectively to measure the mass of hydrogen. In other embodiments, the number of scales can also be configured for on-board hydrogen storage bottles with other design pressures (for example, 40MPa). In the embodiment of the present invention, the scale can be a conventional high-precision scale, and it is preferably installed at the bottom of the hydrogen storage bottle.

[0034] In this embodiment, the sensor component 3 is installed in conjunction with the vehicle-mounted hydrogen storage bottle to measure the temperature value and pressure value of the vehicle-mounted hydrogen storage bottle. The sensor component 3 is preferably a temperature sensor and a pressure sensor for respectively measuring the temperature value and pressure value of the vehicle-mounted hydrogen storage bottle, and the temperature sensor and the pressure sensor are preferably installed on the vehicle-mounted hydrogen storage bottle.

[0035] In this embodiment, the control device 4 is electrically connected to the weight testing device 2 and the sensor assembly 3, and is used to determine the hydrogenation performance of the vehicle-mounted hydrogen storage bottle according to the hydrogen quality, the temperature value and the pressure value. Here, the "electrical connection" of the embodiment of the present invention is used to describe the signal connection between two components, such as a control signal and a feedback signal, and the electrical power connection between two components.

[0036] Among them, the control device 4 can be a PLC (Programmable Logic Controller), but in other embodiments, the control device 4 can also adopt a program controller such as a single-chip microcomputer, a DSP (Digital Signal Processor), or a SOC (System on a Chip).

[0037] In one embodiment, the hydrogenation performance may include the accuracy and safety of hydrogenation to the on-board hydrogen storage bottle. The accuracy is an indicator for judging whether the hydrogen output by the hydrogenation machine of the hydrogenation station is consistent with the hydrogen injected into the on-board hydrogen storage bottle. If the two are inconsistent, it indicates that the on-board hydrogen storage bottle may have leaked, and a safety warning is required in time; the safety is an indicator for judging whether the current hydrogenation process is safe. Due to the long hydrogen storage time, large capacity, high pressure and ambient temperature of the on-board hydrogen storage bottle, there is a risk of hydrogen leakage or hydrogen explosion, so a safety assessment is required. In the example, the accuracy can be determined based on the mass change of the on-board hydrogen bottle. If the mass change and the mass of hydrogen output by the hydrogen refueling machine are within the set accuracy range, it can be determined that the hydrogen storage accuracy of the on-board hydrogen storage bottle at this time is qualified; the safety can be determined based on the temperature value and the pressure value in the on-board hydrogen bottle. If the temperature value and the pressure value exceed the preset safety range, it is determined that the on-board hydrogen storage bottle is in an unsafe state, otherwise the safety is qualified.

[0038] In summary, the hydrogenation test device of the embodiment of the present invention is simple and reliable, and can be freely moved using the mobile platform 1, thereby improving the mobility of the hydrogenation test. In addition, the hydrogenation test device of the embodiment of the present invention realizes real-time monitoring of hydrogenation performance by detecting and processing hydrogen quality, hydrogen storage bottle temperature, and hydrogen storage bottle pressure, which is conducive to ensuring the smooth progress of the hydrogenation process.

[0039] Embodiment 2

[0040] Figure 2 is a schematic diagram of the structure of the hydrogenation test device of the second embodiment of the present invention, relative to Figure 1 The hydrogenation test device shown in the figure may further include a flow test device 5 arranged on the mobile platform 1. The flow test device 5 is arranged at the hydrogenation inlet of the vehicle-mounted hydrogen storage bottle, and is used to measure the hydrogen flow at the hydrogenation inlet.

[0041] Accordingly, with respect to the flow testing device 5 added in the preferred embodiment, the control device 4 is also configured to calculate the hydrogen refueling rate of the on-board hydrogen storage bottle according to the hydrogen flow rate, and combine the hydrogen rate with the hydrogen mass, the temperature value and the pressure value to determine the hydrogen refueling performance of the on-board hydrogen storage bottle.

[0042] In this embodiment, in a preferred embodiment, the flow testing device 5 can use a gas flow meter, and its range can be selected according to the needs of the test site.

[0043] In addition to accuracy and safety, the hydrogenation performance in this embodiment may also include the performance of the hydrogenation rate of hydrogenation to the onboard hydrogen storage bottle. Generally, the hydrogenation process should be as fast as possible, so the hydrogenation rate can be used to determine whether the current hydrogenation rate is within a normal range.

[0044] Regarding the hydrogen rate, accuracy and safety of adding hydrogen to the on-board hydrogen storage bottle, and the function of the above-mentioned control device 4, Figure 3 FIG. 2 shows a schematic diagram of the structure of the control device of this embodiment. Figure 3 As shown, the control device 4 may include: an acquisition module 41, used to obtain the hydrogen flow rate from the flow testing device 5, obtain the temperature value and the pressure value from the sensor component 3, and obtain the hydrogen mass from the weight testing device 2; a calculation module 42, used to calculate the hydrogen rate of adding hydrogen to the on-board hydrogen storage bottle according to the hydrogen flow rate; and a judgment module 43, used to judge whether the rate of adding hydrogen to the on-board hydrogen storage bottle is normal according to the hydrogen rate, judge the accuracy of adding hydrogen to the on-board hydrogen storage bottle according to the hydrogen quality, and judge the safety of adding hydrogen to the on-board hydrogen storage bottle according to the temperature value and the pressure value.

[0045] Among them, the acquisition module 41 is electrically connected to the weight testing device 2, the sensor component 3 and the flow testing device 5 respectively; the method in which the calculation module 42 calculates the hydrogen rate according to the hydrogen flow is very conventional, for example, the corresponding hydrogen rate is reflected by the hydrogen flow per unit time; the judgment module 43 judges whether the rate of hydrogenation to the on-board hydrogen storage bottle is normal, and the accuracy and safety of the scheme can be referred to above and will not be repeated here.

[0046] In addition, in a preferred embodiment, the control device 4 may further include: an alarm module 44, which is used to determine whether to perform an audible and visual alarm according to the judgment result of the judgment module 43. For example, in the case of insufficient accuracy and safety, an audible and visual alarm may be performed by the alarm module 44. In other embodiments, the control device 4 may also be configured with a display screen to display the judgment result of the judgment module 43 and the alarm information of the alarm module 44 in real time.

[0047] Compared with the first embodiment, this embodiment adds the judgment of hydrogen rate, enriches the content of hydrogenation performance evaluation, and can better ensure the smooth progress of hydrogenation process.

[0048] Embodiment 3

[0049] In both the first and second embodiments, the mass of hydrogen is obtained by a weight testing device, and the third embodiment provides a new method for obtaining the mass of hydrogen. The hydrogenation testing device in the third embodiment is the same as that in the second embodiment.

[0050] In this embodiment, the calculation module 42 is further used to calculate the hydrogen mass according to the hydrogen flow rate and / or calculate the hydrogen mass according to the temperature value and the pressure value.

[0051] For example, the calculation module 42 can directly calculate the mass of the hydrogen gas added according to the hydrogen gas flow rate read by the gas flow meter before and after the filling.

[0052] For example, the calculation module 42 can directly calculate the mass of the hydrogen gas added by reading the temperature sensor and the pressure sensor on the vehicle-mounted hydrogen storage bottle before and after filling, and according to the molar mass of hydrogen through the actual state equation of the gas, for example, by the formula PV = (1 + ɑ * P / T) * nRT, where: P is the gas storage pressure, the unit is Pa; V is the gas storage volume, the unit is m 3 ; R is the gas constant, which is 4214 J / (kg.K) for hydrogen; T is the gas storage temperature, in K; ɑ is a constant, and ɑ=1.9155×10 -6 , unit is K / Pa; n is the amount of gas substance in the gas, unit is mol.

[0053] In this way, the hydrogen quality can also be obtained by the method of Example 3, so that the hydrogenation performance can be further judged similar to that of Example 1 or Example 2.

[0054] In addition, unlike the first or second embodiment, the hydrogenation performance of this embodiment may also include the repeatability of the hydrogen quality. Here, repeatability is an indicator for judging whether the measured hydrogen quality is accurate. If the hydrogen quality measured by different methods is the same or substantially the same (i.e., the difference is within a set range), it indicates that the measured hydrogen quality is accurate and has high repeatability. Otherwise, the measured hydrogen quality is inaccurate and has low repeatability.

[0055] Accordingly, the judgment module 43 is also used to judge the repeatability of the hydrogen mass by judging whether the following three are consistent: the hydrogen mass measured by the weight testing device 2; the hydrogen mass calculated by the calculation module 42 based on the hydrogen flow rate; and the hydrogen mass calculated by the calculation module 42 based on the temperature value and the pressure value.

[0056] Based on this, compared with Example 1 and Example 2, this embodiment adds the judgment of the repeatability of hydrogen quality, enriches the content of hydrogenation performance evaluation, and can better ensure the smooth progress of the hydrogenation process.

[0058] The working process of the hydrogenation testing device according to the embodiment of the present invention is specifically described below through an application example, and the application example is applicable to the above-mentioned embodiment 1, embodiment 2 and embodiment 3. Figure 4 This is an application diagram of the hydrogenation test device of this application example, in which there are two onboard hydrogen storage bottles of 35MPa and 70MPa, the weight test device 2 is two high-precision balances, the flow test device 5 is a flow meter, the temperature sensor and the pressure sensor are set on the onboard hydrogen storage bottle and are not shown in the figure, and the control device 4 can be understood through the text description and is not shown in the figure. In addition, refer to Figure 4 The hydrogenation process also involves the use of multiple valves, and the function of each valve can be understood by referring to the existing technology, which will not be described in detail here.

[0060] Step S100, moving the hydrogenation test device to the hydrogenation test site via the mobile platform 1.

[0061] Among them, one hydrogenation test device can perform hydrogenation tests on multiple vehicles. When there is a test demand, the hydrogenation test device needs to be moved to the test site of the corresponding vehicle through the mobile platform 1.

[0062] Step S200, installing the components on the mobile platform 1 together with the hydrogen filling machine and the vehicle-mounted hydrogen storage bottle.

[0063] Among them, the various components refer to high-precision balances, flow meters, sensor components, etc. These components can be fixedly installed on the mobile platform to form an integrated test device, or can be detachably installed on the mobile platform 1, so that when necessary, they can be removed from the mobile platform 1 and installed in a suitable position, and then reinstalled on the mobile platform 1 after the test is completed.

[0064] Step S300, after installation is completed, start the hydrogenation test.

[0065] In step S400, the control device 4 obtains parameters such as hydrogen flow rate, hydrogen quality, hydrogen temperature value, hydrogen pressure value, etc., and performs parameter processing.

[0066] The parameter processing includes calculating the hydrogen rate, determining whether each parameter is within a preset normal range, etc.

[0067] Step S500, based on the parameter processing result of the control device 4, the hydrogenation performance of this hydrogenation process is judged, and corresponding processing is performed according to the hydrogenation performance.

[0068] For example, if the hydrogen rate calculated by the control device is within the preset normal range, the hydrogenation rate is qualified, otherwise an alarm should be considered; if the difference between the calculated hydrogen mass and the hydrogen mass output by the hydrogenator is within the preset range, the accuracy of the hydrogenation process is qualified, otherwise an alarm should be considered; if the calculated hydrogen temperature value and hydrogen pressure value are both within the preset safety range, the safety of the hydrogenation process is qualified; if the difference in hydrogen mass obtained by the control device 4 in different ways is within the preset range, the repeatability of the hydrogenation quality is qualified, otherwise an alarm should be considered.

[0069] It can be seen that the hydrogenation test device of the embodiment of the present invention has good mobility, and one hydrogenation test device can be applied to multiple hydrogenation sites. The hydrogenation test process is simple and reliable, and the hydrogenation performance can be well evaluated to ensure the normal progress of the hydrogenation process.
