Description

Technical Field

[0001] The present invention relates to the field of new energy, and particularly to a hydrogen quantity calculation system and method for hydrogen-using equipment. Background Art

[0002] As a form of energy, hydrogen energy has always been a problem in this field for the acquisition, storage, and use management of hydrogen. For example, there is a lack of data communication between hydrogen production / filling equipment, hydrogen storage equipment, and hydrogen-using equipment, and it is impossible to accurately display the amount of stored hydrogen. When users use hydrogen energy equipment, they also need to know information such as the time and hydrogen quantity required to fill the hydrogen storage equipment, as well as the time that the hydrogen-using equipment can maintain use and the remaining hydrogen quantity.

[0003] In order to inform users of the endurance ability of hydrogen-using equipment, usually through methods such as APPs and display screens, the current remaining hydrogen quantity is informed to users in the form of a percentage. For example, "70 or 70%", which means that based on the maximum hydrogen storage capacity of the hydrogen storage bottle of the hydrogen-using equipment, the current hydrogen-using equipment still has 70% of the hydrogen quantity remaining. When the remaining hydrogen quantity in the hydrogen storage bottle is small, for example, only 25% remains, generally speaking, the consumption speed of the last remaining part of the hydrogen quantity will be faster, giving users faster endurance anxiety.

[0004] Therefore, a new type of hydrogen quantity calculation system and method is needed to alleviate users' endurance anxiety. Summary of the Invention

[0053] Refer to Figure 1 , in an embodiment of the present invention, a hydrogen quantity calculation system for a hydrogen-using device is disclosed. In this embodiment, in order to alleviate the user's range anxiety through software means when it is impossible to hardware-modify the sealing situation and hydrogen release strategy of the hydrogen storage cylinder. Specifically, the hydrogen quantity calculation system includes:

[0054] - Calibration system

[0055] After the hydrogen storage cylinder of the hydrogen-using device is repeatedly used for hydrogen and refilled with hydrogen, there may be a slight difference between the maximum hydrogen storage capacity that can be filled and the previously recorded maximum hydrogen storage capacity. Therefore, it is necessary to periodically calibrate the maximum hydrogen storage capacity of the hydrogen storage cylinder according to the hydrogen that can be filled in the hydrogen storage cylinder of the hydrogen-using device. For example, calibrate once every three months. If the number of times the hydrogen storage cylinder has been refilled with hydrogen reaches a preset value of the maximum number of uses, the calibration period can be adjusted again, for example, recalibrate once every six months.

[0056] Meanwhile, considering the weakening or attenuation of the hydrogen storage capacity of the hydrogen storage cylinder caused by the long-term use (e.g., high-frequency use) or deactivation (long time, such as not used for 3 months) of the hydrogen-using equipment, when the maximum hydrogen storage capacity is constantly changing, in a preferred embodiment, the calibration system will be initialized before the first use after a long period of non-use, and the maximum hydrogen storage capacity of the hydrogen storage cylinder will be recalibrated. The recalibration method can be to fill the hydrogen storage cylinder with hydrogen until it cannot be filled, and calculate the amount of hydrogen filled during this initialization to update the maximum hydrogen storage capacity.

[0057] - Control module

[0058] The control module is connected to the calibration module and receives the accurate maximum hydrogen storage capacity calibrated by the calibration module, so as to know the maximum hydrogen intake capacity of the hydrogen storage cylinder in the hydrogen-using equipment. To alleviate the user's range anxiety, the control module includes a configuration unit, a control unit, and a display unit.

[0059] A hydrogen storage threshold is preset in the configuration unit. The hydrogen storage threshold is less than the maximum hydrogen storage capacity and is used as a measurement standard. After dividing the hydrogen storage threshold by the maximum hydrogen storage capacity, a preset ratio can be obtained.

[0060] The control unit is connected to the configuration unit and receives the hydrogen storage threshold. The control unit will be connected to the hydrogen storage bottle to obtain the current hydrogen amount or the remaining hydrogen amount in the hydrogen storage bottle at the current moment (the acquisition method can be to obtain it after connecting to the pressure sensor of the hydrogen storage bottle and the hydrogen consumption counter at the hydrogen outlet). When the control unit detects that the current hydrogen amount is less than or equal to the hydrogen storage threshold, it means that the condition for triggering the alleviation of the user's range anxiety is met. The control unit will modify the current hydrogen amount to a virtual hydrogen amount, which is less than the current hydrogen amount, so that the information received by the user will be less than the actual value. For example, when the preset ratio is 20% and the current hydrogen amount is only 15% of the maximum hydrogen storage amount, the virtual hydrogen amount can be modified to 12%, which means that the information received by the user is that the hydrogen in the hydrogen storage bottle will be quickly depleted and hydrogen needs to be replenished as soon as possible. Further, the decline rate of the virtual hydrogen amount is different from that of the current hydrogen amount and is non-linear. This means that the current hydrogen amount is calculated by calculating how much hydrogen remains based on the hydrogen release amount in the hydrogen storage bottle and calculating the ratio to the maximum hydrogen storage amount to update the current hydrogen amount (for example, assuming the maximum hydrogen storage amount is 1000 and the current hydrogen amount is 150, and on this basis, when another 50 hydrogen is consumed, the current hydrogen amount is 100); while the modification of the virtual hydrogen amount is that at first the virtual hydrogen amount is less than the current hydrogen amount, but as it is continuously updated, the virtual hydrogen amount still maintains the configuration of being less than the current hydrogen amount, but the difference between the virtual hydrogen amount and the current hydrogen amount becomes smaller and smaller, so that the decline rate of the virtual hydrogen amount is less than that of the current hydrogen amount (for example, assuming the maximum hydrogen storage amount is 1000 and the current hydrogen amount is 150, then the virtual hydrogen amount is 120, and on this basis, when another 50 hydrogen is consumed, the current hydrogen amount is 100 and the virtual hydrogen amount is 80, and the current hydrogen amount drops from 150 to 100 based on the linear comparison of the hydrogen consumption amount with the maximum hydrogen storage amount, while the virtual hydrogen amount drops from 120 to 80 through a non-linear algorithm). This non-linear decline method gives the user the experience that when the current hydrogen amount is just less than the hydrogen storage threshold, the information received by the user is that the remaining hydrogen amount is not much, which is equivalent to getting a reminder to replenish hydrogen as soon as possible; and when the current hydrogen amount is very small, almost zero, that is, all the hydrogen will be depleted, the user will find that the hydrogen amount in the last percentage is particularly durable (this is inseparable from the configuration of the gradually decreasing decline rate), so as to give the user a longer range feeling and avoid the user feeling that the hydrogen is consumed faster when the remaining hydrogen amount is low.

[0061] After having the above virtual hydrogen amount, the display unit will receive the virtual hydrogen amount, calculate the ratio of the virtual hydrogen amount to the maximum hydrogen storage amount as a virtual ratio, and replace the remaining ratio that should be displayed with the virtual ratio, so as to display the virtual ratio in the form of a percentage.

[0062] In a preferred embodiment, the preset ratio is 10%-40%, such that the hydrogen storage threshold is 10%-40% of the maximum hydrogen storage capacity. More specifically, the preset ratio can be 30%, or can be further relaxed to 15% according to the user's feeling needs. Correspondingly, the control unit is configured to: when the current hydrogen amount is greater than the hydrogen storage threshold, the control unit sends the current hydrogen amount to the display unit, so that the display unit calculates the true ratio of the current hydrogen amount to the maximum hydrogen storage capacity and displays the true ratio in the form of a percentage. In other words, when the current hydrogen amount is greater than the hydrogen storage threshold, the percentage of the remaining hydrogen amount will be truly reflected. When the current hydrogen amount is less than the hydrogen storage threshold, adjustments will be made according to the user's psychological feelings, so that the user will not doubt the virtual ratio.

[0063] In a preferred embodiment, the control unit is configured to calculate the virtual hydrogen amount based on the following formula:

[0064]

[0065] where Amount 虚拟 is the virtual hydrogen amount, a is a constant value, and Amount 储氢阈值 is the hydrogen storage threshold, Amount 实际 is the actual hydrogen amount, Amount max is the maximum hydrogen storage capacity. For example, when the maximum hydrogen storage capacity is 1000 (which does not represent a real 1000 units), the hydrogen storage threshold is 300, and the actual hydrogen amount is 250, in the display mode of the prior art, the remaining hydrogen amount obtained by the user is 250, and the percentage of the remaining hydrogen amount is 25%. However, according to the above formula calculation, the virtual hydrogen amount is 187.5; when the maximum hydrogen storage capacity is 1000 (which does not represent a real 1000 units), the hydrogen storage threshold is 400, and the actual hydrogen amount is 180, in the display mode of the prior art, the remaining hydrogen amount obtained by the user is 180, and the percentage of the remaining hydrogen amount is 18%. However, according to the above formula calculation, the virtual hydrogen amount is 129.6; when the maximum hydrogen storage capacity is 1000 (which does not represent a real 1000 units), the hydrogen storage threshold is 300, and the actual hydrogen amount is 90, in the display mode of the prior art, the remaining hydrogen amount obtained by the user is 90, and the percentage of the remaining hydrogen amount is 9%. However, according to the above formula calculation, the virtual hydrogen amount is 24.3. It is ensured that the foregoing virtual hydrogen amount is less than the current hydrogen amount. However, with continuous update, the virtual hydrogen amount still maintains the configuration of being less than the current hydrogen amount, but the difference between the virtual hydrogen amount and the current hydrogen amount becomes smaller and smaller, so that the decline rate of the virtual hydrogen amount is less than the decline rate of the current hydrogen amount.

[0066] Furthermore, the display unit is configured to calculate the virtual ratio based on the following formula:

[0067]

[0068] Where b is a virtual ratio. It can be understood that the calculated virtual ratio may be an extremely small number. For example, as exemplified above: when the maximum hydrogen storage capacity is 1000 (which does not represent a real 1000 units), the hydrogen storage threshold is 300, and the actual hydrogen amount is 90. In the display method of the prior art, the remaining hydrogen amount obtained by the user is 90, and the percentage of the remaining hydrogen amount is 9%. However, according to the above formula, when the virtual hydrogen amount is 24.3, the virtual ratio is 2.43%, or even less than 1%. Then the display unit is further configured that when the virtual ratio is less than c%, the display unit always displays d%, until the remaining hydrogen in the hydrogen storage bottle is exhausted, where d = c ± 1, and when c ≤ 1, d = 1. For example, when c is taken as 3 and d is taken as 2, the user will feel that the displayed virtual ratio can be used for a very long time, and then the hydrogen consumption control strategy for low hydrogen amount of the product is improved. And for the last 1%, the time used is the longest, giving the user a longer battery life feeling.
