This makes it impossible to monitor and determine the battery aging status online in real time to quickly make control decisions. This results in inefficient fuel cell aging control and an inability to respond promptly to fuel cell aging. Furthermore, the accuracy of the control strategy for fuel cell aging is low, making it ineffective in delaying fuel cell aging. Summary of the Invention

[0030] Example 1

[0031] Figure 1 This is a flow chart of a fuel cell aging delay control method provided in the first embodiment of the present invention. This embodiment can be applied to the real-time monitoring of the performance status of automobile fuel cells, the real-time generation of fuel cell aging delay strategies, and the aging delay control of fuel cells based on the aging delay strategies. This method can be executed by a fuel cell aging delay control device, which can be implemented in the form of hardware and / or software, and can be configured in electronic devices. Figure 1 As shown, the method includes:

[0032] S110, obtaining the total battery operation time, current battery current value, current battery voltage value and coolant inlet temperature value of the fuel cell in the current time period, and obtaining the battery initial voltage values corresponding to several preset battery current values.

[0033] S120 , determining battery target voltage values corresponding to respective preset battery current values according to the current battery current value, the current battery voltage value, and the coolant inlet temperature value.

[0034] S130 : Determine a comprehensive aging performance attenuation coefficient according to the battery initial voltage value and the battery target voltage value corresponding to each preset battery current value.

[0035] S140: Determine a battery aging delay control strategy based on the comprehensive aging performance attenuation coefficient and the total battery operation time, and control the fuel cell to delay aging based on the battery aging delay control strategy.

[0036] The method of this embodiment can be executed by the FCU (Fuel Cell Control Unit), and various parameters such as battery voltage value, battery current value and temperature value can be collected by corresponding sensors in the fuel cell system and the collected relevant data can be transmitted to the FCU.

[0037] Among them, the current time period is the data collection period of the current time node, which can be pre-set by relevant technical personnel according to actual needs. For example, the collection frequency can be set. For example, the data collection period can be 10ms.

[0038] The current battery current value of the fuel cell may be the current value of the fuel cell collected during the current time period, and the current battery voltage value of the fuel cell may be the voltage value of the fuel cell collected during the current time period. The current battery current value and the current battery voltage value may be collected by a DC-DC converter (DC-DC converter) of the fuel cell system. The coolant inlet temperature value may be a temperature signal collected by a coolant inlet temperature sensor. The coolant inlet temperature value may also be replaced by the coolant outlet temperature value.

[0039] The total battery operation time can be the total operation time of the fuel cell from the first use to the current time period. The preset battery current value is a current value preset by relevant technical personnel. There are multiple current values, and there are larger or smaller current intervals between each preset current value. The battery initial voltage value corresponding to each preset battery current value can be obtained in advance, and the mapping relationship between the preset battery current value and the corresponding battery preset voltage value is solidified in a map table during the vehicle test phase. For example, the preset battery current value is recorded as I a , I b ,…,I n The initial battery voltage corresponding to the preset battery current value can be expressed as U a0 、U b0 ,…,U n0 .

[0040] The target battery voltage corresponding to each preset battery current value is determined based on the current battery current value, the current battery voltage value, and the coolant inlet temperature value. The target battery voltage value is used to determine the aging performance attenuation coefficient.

[0041] In an optional embodiment, determining the battery target voltage values corresponding to the respective preset battery current values according to the current battery current value, the current battery voltage value, and the coolant inlet temperature value includes:

[0042] Step a1: Determine reference battery current values corresponding to preset current sections and reference battery voltage values corresponding to the reference battery current values according to the current battery current value, the current battery voltage value, and the coolant inlet temperature value.

[0043] Step a2: for any preset battery current value, select a first adjacent current value and a second adjacent current value adjacent to the preset battery current value from each reference battery current value.

[0044] Step a3: using the reference battery voltage value corresponding to the first adjacent current value as the first adjacent voltage value, and using the reference battery voltage value corresponding to the second adjacent current value as the second adjacent voltage value.

[0045] Step a3: Determine a battery target voltage value corresponding to the preset battery current value according to the preset battery current value, the first adjacent current value, the second adjacent current value, the first adjacent voltage value, and the second adjacent voltage value.

[0046] The preset current segments can be pre-set by relevant technical personnel according to actual needs. The pre-divided preset current segments can be expressed as: [I1, I2), [I2, I3), ..., [I N-1 ,I N ). Among them, I N That is I max , set the maximum battery current value; I1 is I min , setting the minimum battery current value. Different preset current segments correspond to reference current values and reference voltage values for that segment. The current intervals between I1, I2, I3, ... can be set to 15A, which can reduce the complexity of subsequent calculations and provide a reasonable data foundation for subsequent calculations.

[0047] In an optional embodiment, determining reference battery current values corresponding to the preset current segments and reference battery voltage values corresponding to the reference battery current values, respectively, based on the current battery current value, the current battery voltage value, and the coolant inlet temperature value, includes:

[0048] Step b1: If the coolant inlet temperature is within a preset temperature range, the battery current value to be compared is determined.

[0049] Step b2: Determine a current deviation between the current battery current value and the current value of the battery to be compared.

[0050] Step b3: determining a reference battery current value of a preset current range to which the current battery current value belongs and a reference battery voltage value corresponding to the reference battery current value according to the current current deviation value.

[0051] The temperature range can be pre-set by relevant technicians. x With the preset temperature value T a Compare and determine the coolant entering the stack temperature T x Is it within the preset temperature range [T a -a,T x +a], if the coolant temperature entering the stack is within the preset temperature range, the battery current value to be compared is determined; if the coolant temperature entering the stack is not within the preset temperature range, the current battery current value and the current battery voltage value are regarded as invalid data. Preferably, T a It can be set to 60°C, that is, when the coolant inlet temperature value meets the preset temperature range, the current fuel cell system can be considered to be in a stable working state, and the battery current and battery voltage collected at this time can be regarded as meaningful values.

[0052] The battery current to be compared is the battery current used to calculate the current deviation with the current battery current. The battery current to be compared in different time periods may be the same or different.

[0053] Optionally, determining the battery current value to be compared includes: obtaining the candidate battery current value in the previous time period, and determining the current deviation value between the current battery current value and the candidate battery current value; if the current deviation value is less than a preset current deviation threshold, and the previous current deviation value in the previous time period is not less than the preset current deviation threshold, then the candidate battery current value is used as the battery current value to be compared.

[0054] If the current battery current is I x(i) , the candidate battery current value in the previous time period is I x(i-1) , then the current deviation value e between the current battery current value and the candidate battery current value i =I x(i) -I x(i-1) If the current deviation value e i Less than the preset current deviation threshold e a , and the previous current deviation value e in the previous time period i-1 Not less than the preset current deviation threshold e a , the current deviation value e in the current time period can be determined i If the current deviation value of the candidate battery is less than the preset current deviation threshold for the first time, the current value of the candidate battery is used as the current value of the battery to be compared. At the same time, the current value of the candidate battery in the previous time period is Ix(i-1) Defined as I x(0) , in order to avoid the deviation e to be less than e a The situation where the recorded current value is unstable due to the increase or decrease, therefore, the subsequent deviation e is less than e a When the current deviation value is calculated and updated to e=I x -I x(0) .

[0055] Specifically, determine the current battery current value I x(i) The battery current value I to be compared x(i-1) or I x(0) The current deviation value e between i According to the current current deviation value, a reference battery current value of the preset current segment to which the current battery current value belongs and a reference battery voltage value corresponding to the reference battery current value are determined.

[0056] Optionally, based on the current current deviation value, the reference battery current value of the preset current segment to which the current battery current value belongs and the reference battery voltage value corresponding to the reference battery current value are determined, including: if the current current deviation value meets the preset deviation threshold judgment condition, and the historical current deviation value in the historical time period within a preset number of times meets the deviation threshold judgment condition, then the historical battery voltage value in the historical time period is obtained; the current battery current value is used as the reference battery current value of the preset current segment to which it belongs; and the voltage average of the historical battery voltage value and the current battery voltage value is used as the reference battery voltage value of the reference battery current value.

[0057] If the current deviation value e i Less than the preset current deviation threshold e a , and the historical current deviation value in the historical time period within the preset number of times is also less than the current deviation threshold value e a For example, the preset number of times can be 10 times, which can be preset by relevant technical personnel according to actual needs. a It can be set to 1A. It can be assumed that the current values obtained several times in a row are under the same operating conditions and belong to the same preset current segment. The current battery current value is used as the reference battery current value for the preset current segment, and the average of the historical battery voltage value and the current battery voltage value is used as the reference battery voltage value for the reference battery current value.

[0058] In a specific embodiment, assuming that the current battery current obtained in the current time period is I m, and the current deviation between the historical battery current and the battery current to be compared in 10 consecutive time periods is less than the preset current deviation threshold, and the battery voltages obtained in 10 time periods (including the current time period) are U1, U2, ..., U 10 If the current battery current I m belongs to the preset current range [I2, I3), then the current battery current I m As the reference battery current value of the preset current section [I2, I3), (U1, U2, ..., U 10 ) / 10 is used as the reference battery voltage value of the preset current segment [I2, I3).

[0059] Based on the above determination method, a reference battery current value and a reference battery voltage value within at least one preset current segment can be obtained. If at least two of the plurality of preset current segments have their reference battery current values and reference battery voltage values determined, then for any preset battery current value, a first adjacent current value and a second adjacent current value adjacent to the preset battery current value can be selected from the reference battery current values.

[0060] For example, if the preset current value is I a , I b ,…,I n , since the reference battery current points I in the preset current segment are collected and recorded 12 (belongs to the preset current range [I1, I2)), I 23 (belonging to the preset current section [I2, I3)) etc. are not equal to the preset current point I in most cases. a , I b ..., therefore, it is necessary to perform linear interpolation based on the reference battery current values and battery voltage values obtained from adjacent preset current intervals before and after the preset current point.

[0061] For example, if the preset battery current value I a At the reference battery current point I 12 and the reference battery current point I 23 When the battery current point I 12 As the preset battery current value I a The first adjacent current value of the reference battery current point I 23 As the preset battery current value I a The second adjacent current value of 12 Corresponding reference battery voltage value U 12 As the first adjacent voltage value, and the second adjacent current value I 23 Corresponding reference battery voltage value U 23 as the second adjacent voltage value.

[0062] According to the preset battery current value, the first adjacent current value, the second adjacent current value, the first adjacent voltage value and the second adjacent voltage value, the battery target voltage value corresponding to the preset battery current value is determined. Continuing with the above example, assuming that the preset battery current value is I a , the first adjacent current value is I 12 , the second adjacent current value is I 23 、The first adjacent voltage value is U 12 and the second adjacent voltage value is U 23 , then the preset battery current value I a The corresponding battery target voltage value U a is determined as follows:

[0063]

[0064] Based on the above method, each preset battery current value I can be obtained a , I b ,…,I n The corresponding battery target voltage value U a 、U b ,…,U n .

[0065] However, it should be noted that since the prerequisite for determining each preset battery current value is that the battery target voltage value for the preset battery current value can be determined when at least two sets of reference battery current values for the preset current segments are obtained, it is possible that some preset current segments do not have corresponding reference battery current values and reference battery voltage values. Therefore, if some reference battery current values and reference battery voltage values exist, the preset current segments without reference current and reference voltage data are skipped, and the reference battery current and reference battery voltage values for the current intervals are continuously acquired.

[0066] For example, if there is data in the preset current segment [I1, I2) and no data in [I2, I3), the preset battery current value I is calculated by linear interpolation. a The target battery voltage value U a In the process, the data of [I3,I4) is used for U a The above target battery voltage value U a The determination method is updated as follows:

[0067]

[0068] In addition, when the preset battery current value exceeds each preset current segment, that is, I a Less than I min or greater than I max Assume that the preset battery current value is Ia 40A, [I1, I2) is [45, 60), [I2, I3) is [60, 75), the preset battery current value I is determined at this time a The first adjacent current value is I 12 , belongs to the preset current section [I1, I2), the first adjacent current value I 12 The preset battery current value is 50A. a The second adjacent current value is I 23 , belongs to the preset current section [I2, I3), the second adjacent current value I 23 is 70A, the first adjacent current value I 12 The corresponding first adjacent voltage value U 12 is 0.85, the second adjacent current value I 23 The corresponding second adjacent voltage value U 23 is 0.83, then the battery target voltage value That is, U a Equal to 0.86.

[0069] The above technical solution introduces the coolant inlet temperature value judgment condition and the current deviation value judgment condition in the process of determining the battery target voltage value corresponding to the preset battery current value, and adopts special processing methods to determine the battery target voltage value under different special circumstances, thereby achieving accurate determination of the battery target voltage value, thereby further improving the subsequent accuracy of determining the comprehensive aging performance attenuation coefficient, and further improving the precise control of delayed aging of fuel cells.

[0070] The comprehensive aging performance attenuation coefficient is used to characterize the degree of fuel cell performance degradation, and its value range is typically [0, 1]. A smaller comprehensive aging performance attenuation coefficient, or the closer it is to 0, indicates more severe fuel cell performance degradation. A larger comprehensive aging performance attenuation coefficient, or the closer it is to 1, indicates less severe fuel cell performance degradation.

[0071] In an optional embodiment, a comprehensive aging performance attenuation coefficient is determined based on the battery initial voltage value and the battery target voltage value corresponding to each preset battery current value, including: for any preset battery current value, the ratio between the battery target voltage value and the battery initial voltage value of the preset battery current value is used as the battery aging performance attenuation coefficient of the preset battery current value; according to the battery aging performance attenuation coefficient corresponding to each preset battery current value, based on a preset aging coefficient weight value, a comprehensive aging performance attenuation coefficient is determined.

[0072] For any preset battery current value I i The target battery voltage value of the preset battery current value is recorded as U i The initial battery voltage value of the preset battery current value is recorded as Ui0 , then the preset battery current value I i The battery aging performance attenuation coefficient δ i For U i / U i0 .

[0073] According to the preset battery current value I a , I b ,…,I n The corresponding battery aging performance attenuation coefficient δ a , δ b ,…,δ n , based on the preset aging coefficient weight value α a , α b ,…,α n , determine the comprehensive aging performance attenuation coefficient δ as:

[0074] δ=δ a *α a +δ b *α b +…+δ n *α n ;

[0075] A battery aging delay control strategy is determined based on the comprehensive aging performance attenuation coefficient and the total battery operation time, and the fuel cell is controlled to delay aging based on the battery aging delay control strategy. In the process of generating the battery aging control strategy, both the impact of the comprehensive aging performance attenuation coefficient and the total battery operation time are taken into account. In an optional embodiment, the battery aging delay control strategy is determined based on the comprehensive aging performance attenuation coefficient and the total battery operation time, including:

[0076] Step c1: If the comprehensive aging performance attenuation coefficient is greater than a preset attenuation coefficient threshold, and the total battery operation time is greater than a preset time threshold, the battery aging delay control strategy is to control and reduce the battery power change gradient value.

[0077] Step c2: If the comprehensive aging performance attenuation coefficient is greater than a preset attenuation coefficient threshold and the total battery operation time is not greater than a preset time threshold, the battery aging control strategy is to generate a fault alarm message indicating abnormal battery aging performance attenuation.

[0078] The attenuation coefficient threshold and the duration threshold can be pre-set by relevant technical personnel according to actual needs. For example, the attenuation coefficient threshold can be set to 12%, and the duration threshold can be set to 10,000 hours.

[0079] If the comprehensive aging performance attenuation coefficient is greater than the preset attenuation coefficient threshold, and the total battery operation time is greater than the preset time threshold, the battery power change gradient value is controlled to reduce to avoid drastic load changes in the fuel cell and delay aging.

[0080] If the combined aging performance attenuation coefficient exceeds a preset attenuation coefficient threshold, and the total battery operating time is no longer than a preset duration threshold, a fault alarm indicating abnormal battery aging performance attenuation is generated. This fault alarm alerts personnel to the abnormal aging performance attenuation of the fuel cell, allowing them to manually determine the cause of the abnormality.

[0081] If the comprehensive aging performance attenuation coefficient is less than a preset attenuation coefficient threshold, the fuel cell aging delay control is not performed.

[0082] The above technical solution takes into account the total battery operation time when determining the fuel cell aging delay strategy, so as to further analyze whether the state of fuel cell aging performance degradation is abnormal, thereby improving the accuracy of generating the fuel cell aging delay strategy.

[0083] The technical solution of the embodiment of the present invention determines the battery target voltage corresponding to each preset battery current value based on the obtained current battery current value, current battery voltage value, and the coolant inlet temperature value. It then determines the comprehensive aging performance attenuation coefficient based on the battery initial voltage value and battery target voltage value corresponding to each preset battery current value. It then determines the battery aging delay control strategy based on the comprehensive aging performance attenuation coefficient and the total battery operating time. The fuel cell aging delay is controlled based on the battery aging delay control strategy. This enables real-time monitoring of fuel cell performance aging and real-time generation of the fuel cell aging delay strategy, thereby enabling rapid and timely response to fuel cell aging delay and improving fuel cell aging control efficiency. By determining the comprehensive aging performance attenuation coefficient to determine the battery aging delay control strategy, the accuracy of determining the fuel cell aging delay strategy is improved, thereby achieving precise control of fuel cell aging delay. By determining the comprehensive aging performance attenuation coefficient based on the determined battery target voltage values at different preset battery current points, the accuracy of determining the comprehensive aging performance attenuation coefficient is improved, thereby improving the accuracy of determining the fuel cell aging delay strategy.

[0084] Example 2

[0085] Figure 2This is a flow chart of a fuel cell aging delay control method provided in the second embodiment of the present invention. This embodiment provides a preferred example based on the above embodiment. It is executed by the control device FCU of the fuel cell system. The FCU receives the battery current and voltage signals from the DCDC and the temperature signal from the coolant inlet temperature sensor, calculates and records the program data in the storage unit, and then outputs the control to the air compressor and other actuators through the processing unit. When the vehicle stops, the FCU storage unit will record the voltage, current and calculated performance attenuation coefficient data collected before the stop. When the vehicle restarts and runs, the aforementioned current, voltage and other data will be read directly from the storage unit. Figure 2 As shown, the method includes the following specific steps:

[0086] Step 1: Monitor the coolant inlet temperature, fuel cell current and voltage, and fuel cell operation time in real time.

[0087] Step 2: The collected coolant temperature value T x With the preset temperature value T a By comparison, if the coolant inlet temperature T x At the preset temperature T a Within the allowable range, that is, T a +a≥T x ≥T a -a, then proceed to the next step to segment the current interval; otherwise, directly determine the voltage and current values of the fuel cell as invalid data.

[0088] The coolant inlet temperature can also be replaced by the coolant outlet temperature. Preferably, the preset temperature value T a When the temperature is 60℃, the fuel cell system is considered to be in a stable working state, and the voltage and current values collected at this time are meaningful.

[0089] Step 3: The collected current value I x Divide into segments according to the preset current range.

[0090] Among them, the maximum current value output by the fuel cell stack is recorded as I max , the preset N-1 current intervals are segmented and can be divided into [I1, I2), [I2, I3)…, [I N-1 , I N ], where I N That is I max 、I1 is I min , so I1 is generally the minimum current of the fuel cell at idle speed, I N is the peak current of the fuel cell. When the current value I xWhen it is greater than or equal to I2 and less than I3, it is divided into [I2, I3) and the current value is recorded as I 23 ; When the collected current value I x When it is greater than or equal to I3 and less than I4, it is divided into [I3, I4) and the current value is recorded as I 34 Preferably, the intervals between the current intervals I1, I2, I3, etc. can be set to 15A, which can reduce the complexity of subsequent calculations and provide a reasonable data basis for subsequent calculations.

[0091] Step 4: further determine the validity of the collected current and voltage data by calculating the deviation between the current value currently collected and the current value collected in the previous sampling period.

[0092] Step 4.1. Calculate the current value I currently collected x(i) Compared with the current value I collected in the previous sampling period x(i-1) ) of the deviation e. Therefore, the formula for the deviation e is e=I x(i) -I x(i-1) .

[0093] Step 4.2: The deviation e is smaller than the preset deviation e for the first time. a When the current value I collected in the previous sampling period is recorded x(i-1) , and defined as I x(o) In order to avoid the deviation e to be less than e a The increasing or decreasing situation causes the recorded current value to be unstable, so the formula of the deviation e is changed to e=I x(i) -I x(0) Preferably, the preset deviation e a If the preset deviation value is too large, the accuracy of subsequent calculations will be reduced.

[0094] Step 4.2: If the deviation e is less than the preset deviation e for Ti consecutive sampling periods a , then the current and voltage values collected at this time are regarded as valid data, and the average voltage value U of the current point within Ti sampling cycles is recorded. In the embodiment, if the current current is I 23 , then the average voltage recorded at this time is U 23 Preferably, Ti is 10, which means that the fuel cell system is in a stable state.

[0095] It should be noted that when the deviation e is greater than the preset deviation e aIf the current operating condition is different, it can be considered that the current value currently obtained belongs to another preset current range. Steps 4.1 to 4.3 are then repeated. The current value and voltage value for each preset current range are obtained. The last current value obtained for that range is used as the current value for that range, and the average of the continuously obtained voltage values for that range is used as the voltage value for that range.

[0096] Step 5: Calculate the preset current point I a , I b ...voltage value under.

[0097] Since the current point I 12 , I 23 ...is not equal to the preset current point I in most cases a , I b ..., therefore, it is necessary to perform linear interpolation based on the current and voltage values obtained from the current intervals before and after the preset current point. a The size is located in I 12 and I 23 Between

[0098] Step 6: Ratio the real-time voltage collected at the same current point to the initial state voltage to obtain the aging performance attenuation coefficient δ of different current intervals. a , δ b ...etc., i.e.

[0099] Among them U a0 The preset current point I in the initial state of the stack a The voltage value below.

[0100] Step 7: Weighting is performed according to different current intervals to finally obtain the comprehensive aging performance attenuation coefficient δ, which is used to characterize the aging state of the fuel cell, that is, δ = δ a *α a +δ b *α b +….

[0101] The initial state voltage may be a map table solidified during the vehicle experiment phase, or may be the first batch of data collected in real time after the vehicle leaves the factory.

[0102] Step 8: Control the delayed aging of the fuel cell based on the comprehensive aging performance attenuation coefficient.

[0103] When the comprehensive aging performance attenuation coefficient exceeds the preset threshold δ xtmin , where the preset threshold δ xtminAccording to different current ranges and the total operating time of the fuel cell, there are two situations. First, if the total operating time of the fuel cell is greater than the preset time threshold t min , then based on the aging performance attenuation coefficient value in this current range, the power change gradient value ΔP is reduced to avoid drastic load changes in the fuel cell and delay aging. Secondly, if the total operating time of the fuel cell is less than the preset time threshold, a fuel cell aging performance attenuation abnormal fault is reported.

[0104] In the embodiment, if the total operating time t of the fuel cell monitored in real time is greater than the preset threshold value of 10,000 hours, at the current point I a When the current is 65A, the calculated aging performance attenuation coefficient δ a is 12%, which is greater than the preset threshold of 10% amin Therefore, it is necessary to reduce ΔP, for example, from the original 30kW to 20kW. If the total operating time t of the fuel cell monitored in real time is less than the preset threshold value of 10,000 hours, at the current point I a When the current is 65A, the calculated aging performance attenuation coefficient δ a is 12%, which is greater than the preset threshold of 10% amin , then it will report the abnormal degradation of fuel cell aging performance.

[0105] It should be noted that the preset current point I is calculated by linear interpolation. a , I b The voltage value U of ... a 、U b ...there are two things to note and solutions. First, when the vehicle is driving, some current intervals cannot be covered, resulting in no data in some current intervals. Therefore, the preset current point I a , I b …it may not be possible to directly use the previous and next current intervals without data for linear interpolation. In this case, it is necessary to skip the current interval without data and continue to acquire the current and voltage values of the current interval. That is, if [I1, I2) has data and [I2, I3) has no data, then linear interpolation is used to solve U. a When [I2, I3) is skipped, [I3, I4) is used. Secondly, when the preset current point I a , I b ...when the recorded effective current interval is exceeded, that is, I a Less than I min or greater than I max , then the linear extrapolation method is used to obtain the corresponding voltage value. The voltage acquisition method under the preset current value is described as follows: if the preset current value I a is 65, and [I1, I2) is [45, 60), [I2, I3) is [60, 75). At this time, the current value I collected by the vehicle is12 and I 23 Both have values, 50 and 70 respectively, corresponding to the voltage value U 12 and U 23 are 0.85 and 0.83 respectively, then the voltage That is U a Equal to 0.835.

[0106] For the first case, that is, [I2, I3) has no data, [I3, I4) is [75, 90), the current value collected by the vehicle is I 12 The value is 50, and I 23 No value needs to be further taken to have a value I 34 , respectively 50 and 80, corresponding to the voltage value U 12 and U 34 are 0.85 and 0.81 respectively, then the voltage That is U a =0.83. If the second situation occurs, that is, I a is 40 and [I1, I2) is [45, 60), [I2, I3) is [60, 75). In this case, the current value I collected by the vehicle needs to be used. 12 and I 23 , respectively 50 and 70, corresponding to the voltage value U 12 and U 23 are 0.85 and 0.83 respectively, then the voltage That is U a Equal to 0.86.

[0107] In summary, by monitoring the effective stack current and voltage data online in real time through the fuel cell controller, self-performance monitoring of the fuel cell system covering all working conditions is achieved, and the performance decay rate is calculated based on real-time data as the basis for the aging status of the fuel cell, thus realizing self-judgment of the aging status of the fuel cell; dynamic ΔP control and aging performance decay fault alarm are realized according to the performance decay rate in different current intervals and the total operating time of the fuel cell, thereby effectively delaying the further aging of the fuel cell and providing an adaptive solution for fuel cell life management.
