Background
Fuel Cell Vehicles (FCV) are driven by combustion of hydrogen gas. In general, a fuel cell vehicle stores hydrogen gas using an on-vehicle hydrogen storage device, and the remaining amount of hydrogen gas in the hydrogen storage device is proportional to the mileage in which the vehicle can be driven.

Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
The temperature acquisition method and apparatus of the hydrogen storage device according to the embodiment of the present application will be described below with reference to the drawings.
In the present application, the process of hydrogenation to the hydrogen storage device is divided into stages of preliminary hydrogenation, identification, and the like. Specifically, after the preliminary hydrogenation is completed, whether the hydrogen storage equipment needs to be continuously hydrogenated or not is judged by acquiring and identifying the temperature of the hydrogen in the hydrogen storage equipment. If the hydrogen is required to be continuously hydrogenated to the hydrogen storage equipment, the preliminary hydrogenation step is indicated, the residual amount of the hydrogen in the hydrogen storage equipment is not in an allowable range, namely the current hydrogenation process is not finished, and the next preliminary hydrogenation and identification step needs to be executed circularly until the hydrogen is not required to be continuously hydrogenated to the hydrogen storage equipment; if it is recognized that the hydrogen storage device is not required to be continuously hydrogenated, indicating that the residual amount of hydrogen in the hydrogen storage device is within the allowable range through the preliminary hydrogenation step, the current hydrogenation process can be ended.
Fig. 1 is a flowchart of a method for obtaining a hydrogen temperature in a hydrogen storage device according to an embodiment of the present disclosure. As shown in fig. 1, the method for obtaining the hydrogen gas temperature in the hydrogen storage device according to the embodiment of the present application includes the following steps:
s101, obtaining a temperature change curve of the thermistor in the hydrogen storage equipment.
Optionally, after the preliminary hydrogenation is finished, the detection temperature of the thermistor can be continuously obtained, and a temperature change curve of the thermistor can be formed according to the detection temperature and the detection time.
S102, acquiring a first intercept of a temperature change curve in a preset time interval.
Alternatively, a temperature change curve in a preset time interval may be extracted from the temperature change curve of the thermistor in the hydrogen storage device, and a linear fitting may be performed on the temperature change curve of the portion to obtain an intercept of the fitted straight line, and the intercept is labeled as a first intercept. The preset time interval can be set according to actual conditions. For example, the preset time interval may be set to 10 s.
S103, acquiring the target temperature of the hydrogen in the hydrogen storage equipment according to the first intercept.
Optionally, after the first intercept is obtained, the mapping relationship between the preset intercept and the temperature may be queried by using the first intercept as a query condition, and the temperature corresponding to the first intercept is obtained as the target temperature.
For example, the first intercept corresponding to the temperature change curve within 180s to 190s is 55.639, and the temperature corresponding to the first intercept is 77.660 ℃, that is, 77.660 ℃ can be obtained as the target temperature by referring to table 1.
| Intercept of a beam | Temperature (. degree.C.) |
| 43.205 | 51.820 |
| 50.805 | 67.627 |
| 55.639 | 77.660 |
| 63.188 | 81.810 |
TABLE 1
From this, this application can acquire the first intercept in the time interval of predetermineeing according to thermistor's temperature variation curve, then according to thermistor's that synchronous collection temperature variation curve and temperature sensor's temperature variation curve, establish the mapping relation between intercept and the temperature, thereby make after preliminary hydrogenation, can be through the mapping relation between inquiry intercept and the temperature, acquire the temperature of hydrogen in the hydrogen storage equipment fast, the problem of the consuming time that exists among the acquisition method of hydrogen temperature in the current hydrogen storage equipment is of a specified duration, inefficiency has been avoided.
In the present application, a mapping relationship between the intercept and the temperature is set in advance. Since the thermistor is a part of an On-tank valve (OTV), a temperature change curve of the thermistor and a temperature change curve of the temperature sensor may be obtained through experiments before the thermistor is installed in the OTV, and a mapping relationship between an intercept and a temperature is previously constructed. The temperature sensor may be selected according to actual conditions, and for example, may be selected as a thermocouple type temperature sensor.
As a possible implementation manner, the temperature of the thermistor and the temperature of the temperature sensor may be synchronously collected to form a temperature change curve of the thermistor and a temperature change curve of the temperature sensor.
Alternatively, the temperature of the thermistor and the temperature of the temperature sensor may be synchronously acquired, the temperature change curve of the thermistor may be formed based on the temperature of the thermistor, and the temperature change curve of the temperature sensor may be formed based on the temperature of the temperature sensor.
For example, the temperature variation of the thermistor and the temperature sensor at 50 ℃, 65 ℃, 75 ℃ and 85 ℃ in the synchronous acquisition is shown in fig. 2. In the figure, the solid line indicates the temperature change curve of the thermistor formed based on the temperature of the thermistor, and the broken line indicates the temperature change curve of the temperature sensor formed based on the temperature of the temperature sensor.
Further, a mapping relation between the intercept and the temperature can be constructed according to a temperature change curve of the thermistor and a temperature change curve of the temperature sensor.
It should be noted that, for different thermistors, the mapping relationship between the intercept and the temperature is different. Therefore, before the thermistor on the vehicle is updated due to maintenance and the like, the mapping relation between the intercept and the temperature is kept unchanged; after the thermistor is updated, the current temperature change curve of the thermistor and the temperature change curve of the temperature sensor need to be obtained again before a new thermistor is installed on the OTV, so as to construct the current mapping relationship between the intercept and the temperature.
It should be noted that the first cutoff distance is obtained according to a temperature change curve in a preset time interval, where although the preset time interval is a short time range, the temperature in the short time range still changes unevenly, which may cause a certain error to the value of the obtained first cutoff distance; in addition, the thermistor can start to measure the hydrogen temperature when an Electronic Control Unit (ECU) is in an on state, but the ECU is in an off state during the hydrogenation process, and after the hydrogenation is finished, the ECU is turned on again, so that a certain time delay exists when the thermistor is used for measuring. Therefore, the time delay may also cause a certain error to the acquired value of the first intercept.
In summary, in order to obtain the obtained first intercept more accurately so as to obtain a more accurate target temperature of the hydrogen in the hydrogen storage device, in the application, the value of the obtained first intercept may be corrected on the basis of the obtained first intercept to obtain a corrected first intercept. The correction factor can be set in advance based on experimental measurements.
Further, a target temperature of the hydrogen gas in the hydrogen storage device may be obtained based on the corrected first intercept.
It should be noted that the temperature of the hydrogen gas in the hydrogen storage device may reflect the remaining amount of hydrogen gas in the hydrogen storage device. Therefore, after the initial hydrogenation of the hydrogen storage equipment is finished, the target temperature can be compared with the preset temperature, and whether the hydrogen addition to the hydrogen storage equipment needs to be stopped or not is judged according to the comparison result, so that the safety of the hydrogen storage equipment is ensured while the hydrogenation quantity requirement of the hydrogen storage equipment is met. Wherein the preset temperature is a critical value for judging whether the content of the hydrogen in the hydrogen storage equipment exceeds an allowable range.
Alternatively, the target temperature may be compared with a preset temperature, and if it is recognized that the target temperature reaches the preset temperature, the hydrogen supply to the hydrogen storage device is stopped, and corresponding measures are taken to ensure that the residual amount of hydrogen can be kept within an allowable range; and if the identified target temperature does not reach the preset temperature, continuously adding hydrogen into the hydrogen storage equipment.
In the present application, the hydrogen adding process to the hydrogen storage device is completed until the recognition result indicates that the control stops adding hydrogen to the hydrogen storage device.
Therefore, the hydrogen residual quantity in the hydrogen storage equipment can be accurately known by comparing the target temperature with the preset temperature, so that whether to continue to hydrogenate to the hydrogen storage equipment can be accurately judged, and the safety of the hydrogen storage equipment is ensured.
In order to implement the above embodiments, as shown in fig. 3, the present application proposes a flow chart of another method for obtaining the hydrogen gas temperature in a hydrogen storage device, which includes the following steps:
s201, acquiring a temperature change curve of the thermistor in the hydrogen storage equipment.
S202, acquiring a first intercept of a temperature change curve in a preset time interval.
And S203, correcting the acquired first cutting distance.
And S204, inquiring the mapping relation between the intercept and the temperature according to the corrected first intercept, and obtaining the target temperature of the hydrogen in the hydrogen storage equipment.
Wherein, the mapping relation between intercept and temperature is preset in the application.
And S205, identifying whether the target temperature reaches a preset temperature.
If it is recognized that the target temperature reaches the preset temperature, step S306 may be performed; if the recognition target temperature does not reach the preset temperature, step S307 may be performed.
S206, stopping adding hydrogen into the hydrogen storage device, and taking corresponding measures to ensure that the residual amount of hydrogen can be kept in an allowable range.
And S207, continuously hydrogenating the hydrogen storage equipment.
