Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of fuel cell power limitation, and in particular to a fuel cell power adaptive control method, device, equipment and computer-readable storage medium. Background Art

[0002] New energy vehicles are equipped with fuel cells as a power source. As the power of the fuel cells matching the vehicle gradually increases, the demand for the cooling system of the same type also increases synchronously. In certain high-temperature environments, or in scenarios where the cooling system partially fails and the cooling capacity is affected, if the fuel cell continues to operate at high power, it is easy to trigger an over-temperature fault. The fuel cell limits power operation or shuts down according to the temperature to protect the fuel-electric system. However, the existing fuel cell over-temperature limit strategy limits the power of the fuel cell according to the pre-calibrated temperature-power relationship. The flexibility of the power limit of the fuel cell is poor, which leads to low working efficiency of the fuel cell. Summary of the invention

[0003] In view of the above problems, embodiments of the present invention provide a method, device, apparatus and computer-readable storage medium for adaptively controlling fuel cell power, which are used to achieve adaptive adjustment of fuel cell power limit and improve the flexibility of fuel cell power control.

[0004] According to one aspect of an embodiment of the present invention, there is provided a method for adaptively controlling fuel cell power, the method comprising:

[0005] Obtain the real-time ambient temperature of the fuel cell system;

[0006] When the real-time ambient temperature is greater than or equal to a preset temperature threshold, dynamically controlling a first limited power of the fuel cell system based on the real-time ambient temperature and a preset power limit relationship until the real-time ambient temperature is lower than the preset temperature threshold;

[0007] Wherein, the preset power limit relationship calibrates the power limit range of the target ambient temperature; the target ambient temperature is a range of ambient temperatures exceeding a preset temperature threshold;

[0008] During the process of dynamically controlling the first limiting power of the fuel cell system, if the real-time ambient temperature of the fuel cell system continues to be lower than the preset temperature threshold for more than a first time, based on the first relationship of the current limiting power value of the fuel cell system, the first limiting power of the fuel cell system is dynamically controlled, and the preset power limiting relationship is corrected until the real-time ambient temperature of the fuel cell system is greater than or equal to the preset temperature threshold.

[0009] Specifically, the adaptive control method of fuel cell power provided by the present application limits the power of the vehicle by means of the power limit range of the ambient temperature calibrated by the preset power limit relationship when the real-time ambient temperature of the vehicle fuel cell system exceeds the limit. During the process of vehicle power limitation, if the real-time ambient temperature of the fuel cell system continues to be lower than the preset temperature threshold for more than the first time, the technical solution of the present application can dynamically adjust the power limit according to the environment in which the vehicle is located, gradually increase the power limit until the maximum power limit of the fuel cell system is reached, which not only ensures that the fuel cell does not overheat during use, but also maximizes the power output required for driving, avoids interruptions or creeping of driving, and improves the flexibility of fuel cell power control.

[0010] In an optional manner, the ambient temperature is detected by an ambient temperature sensor installed on the air inlet side of the radiator of the fuel-electric system.

[0011] In an optional manner, dynamically controlling the power limit of the fuel cell system based on the real-time ambient temperature and the preset power limit relationship includes:

[0012] Based on a preset power limit relationship, determining a power limit range corresponding to the real-time ambient temperature;

[0013] The power limit of the fuel cell system is controlled to be within a corresponding power limit range.

[0014] Specifically, when the real-time ambient temperature of the vehicle fuel cell system exceeds the limit, the technical solution of the present application limits the power of the vehicle by using the power limit range of the ambient temperature calibrated by the preset power limit relationship, thereby ensuring that the fuel cell does not overheat during use.

[0015] In an optional manner, if the power of the fuel cell system is controlled to exceed a second time within the corresponding power limit range and the real-time ambient temperature is still greater than or equal to a preset temperature threshold, the second limit power of the fuel cell system is dynamically controlled based on a second relationship of the current limit power value of the fuel cell system, and the preset power limit relationship is corrected until the real-time ambient temperature is lower than the preset temperature threshold.

[0016] In an optional manner, based on the second relationship of the current limit power value of the fuel cell system, dynamically controlling the second limit power of the fuel cell system and correcting the preset power limit relationship includes:

[0017] Based on the second relationship of the current limiting power value of the fuel cell system, the second limiting power of the fuel cell system is reduced once every third time period until the real-time ambient temperature of the fuel cell system is less than a preset temperature threshold, and then the preset power limiting relationship is corrected according to the current ambient temperature value of the fuel cell system and the current limiting power value.

[0018] Specifically, during the process of vehicle power limitation, if the power of the fuel cell system is controlled to exceed the second time within the corresponding power limit range, and the real-time ambient temperature is still greater than or equal to the preset temperature threshold, the technical solution of the present application can dynamically adjust the power limit according to the environment in which the vehicle is located, and gradually reduce the power limit until it reaches the appropriate power limit of the fuel cell system, thereby further ensuring that the fuel cell is used without over-temperature failure and improving the flexibility of the power control of the fuel cell.

[0019] In an optional manner, dynamically controlling the limit power of the fuel cell system based on the second relationship of the current limit power value of the fuel cell system further includes:

[0020] If the power of the fuel cell system is limited to be less than or equal to the first power value for more than a fourth time, and the real-time ambient temperature is still greater than or equal to the preset temperature threshold, the fuel cell system is controlled to shut down and an alarm notification is issued.

[0021] In an optional manner, based on the first relationship of the current limit power value of the fuel cell system, dynamically controlling the first limit power of the fuel cell system and correcting the preset power limit relationship include:

[0022] Based on a first relationship of a current limit power value of the fuel cell system, increasing a first limit power of the fuel cell system every fifth time until a real-time ambient temperature of the fuel cell system is greater than or equal to a preset temperature threshold;

[0023] Among them, when the limit power of the fuel cell system is increased to a fifth time and the real-time ambient temperature of the fuel cell system remains lower than a preset temperature threshold within the fifth time range, the preset power limit relationship is corrected according to the current ambient temperature value and the current limit power value of the fuel cell system.

[0024] Specifically, during the process of vehicle power limitation, if the real-time ambient temperature of the fuel cell system continues to be lower than the preset temperature threshold for more than a first time, the technical solution of the present application can dynamically adjust the power limit according to the vehicle environment, and increase the first limit power of the fuel cell system every fifth time until the maximum power limit of the fuel cell system is reached. According to the current ambient temperature value and the current limit power value of the fuel cell system, the preset power limit relationship is corrected, which not only ensures that the fuel cell is not over-temperature-failed, but also maximizes the power output required for driving, avoids driving interruptions or creeping, and improves the flexibility of fuel cell power control.

[0025] According to another aspect of an embodiment of the present invention, there is provided an adaptive control device for fuel cell power, comprising: a temperature measurement module, an over-temperature power limiting module and an adaptive adjustment module;

[0026] The temperature measurement module is used to obtain the real-time ambient temperature of the fuel cell system;

[0027] The over-temperature power limiting module is used to dynamically control a first limited power of the fuel cell system based on the real-time ambient temperature and a preset power limiting relationship when the real-time ambient temperature is greater than or equal to a preset temperature threshold, until the real-time ambient temperature is lower than the preset temperature threshold;

[0028] Wherein, the preset power limit relationship calibrates the power limit range of the target ambient temperature; the target ambient temperature is a range of ambient temperatures exceeding a preset temperature threshold;

[0029] The adaptive adjustment module is used to dynamically control the first limiting power of the fuel cell system and correct the preset power limiting relationship based on a first relationship of a current limiting power value of the fuel cell system during the process of dynamically controlling the first limiting power of the fuel cell system, if the real-time ambient temperature of the fuel cell system continues to be lower than a preset temperature threshold for more than a first time, until the real-time ambient temperature of the fuel cell system is greater than or equal to the preset temperature threshold.

[0030] Specifically, the adaptive control device for fuel cell power provided by the present application uses an over-temperature power limiting module to limit the power of the vehicle when the real-time ambient temperature of the vehicle fuel cell system exceeds the limit, using the power limit range of the ambient temperature calibrated by the preset power limit relationship. During the process of vehicle power limitation, if the real-time ambient temperature of the fuel cell system continues to be lower than the preset temperature threshold for more than the first time, the present application uses an adaptive adjustment module to dynamically adjust the power limit according to the environment in which the vehicle is located, and gradually increases the power limit until it reaches the maximum power limit of the fuel cell system, which not only ensures that the fuel cell is used without over-temperature failure, but also maximizes the power output required for driving, avoids interruptions or creeping of driving, and improves the flexibility of fuel cell power control.

[0031] According to another aspect of an embodiment of the present invention, there is provided an adaptive control device for fuel cell power, comprising: a processor, a memory, a communication interface and a communication bus, wherein the processor, the memory and the communication interface communicate with each other via the communication bus; the memory is used to store at least one executable instruction, wherein the executable instruction enables the processor to perform the operation of the adaptive control method for fuel cell power as described in any one of the above items.

[0042] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0043] Embodiment 1, Figure 1 The flowchart of an embodiment of the method for adaptively controlling the power of a fuel cell of the present invention is shown, and the method is executed by an adaptive control device for the power of a fuel cell. Figure 1 As shown, the method comprises the following steps:

[0044] Step 110: Obtain the real-time ambient temperature of the fuel cell system.

[0045] Preferably, the ambient temperature is detected by an ambient temperature sensor installed on the air inlet side of the fuel-electric system radiator. The ambient temperature sensor can detect the ambient air temperature, and the control device monitors the temperature of the air inlet of the fuel-electric system radiator in real time.

[0046] Step 120: When the real-time ambient temperature is greater than or equal to a preset temperature threshold, dynamically controlling a first limited power of the fuel cell system based on the real-time ambient temperature and a preset power limit relationship until the real-time ambient temperature is lower than the preset temperature threshold;

[0047] The preset power limit relationship calibrates the power limit range of the target ambient temperature; the target ambient temperature is a range of several ambient temperatures exceeding a preset temperature threshold.

[0048] In some embodiments of the present invention, dynamically controlling the power limit of the fuel cell system based on the real-time ambient temperature and the preset power limit relationship includes:

[0049] Based on a preset power limit relationship, determining a power limit range corresponding to the real-time ambient temperature;

[0050] The power limit of the fuel cell system is controlled to be within a corresponding power limit range.

[0051] Specifically, the preset temperature threshold is the size of the temperature limit. When the real-time ambient temperature is greater than or equal to the preset temperature threshold, it means that the fuel cell system is over-temperature and needs to be cooled.

[0052] In some embodiments of the present invention, the power limit range for several ambient temperatures exceeding a preset temperature threshold is calibrated according to the vehicle radiator capacity.

[0053] Preferably, the control device uses a map table to record the preset power limit relationship, each ambient temperature corresponds to a power limit value, and the higher the ambient temperature, the lower the power limit value. When the real-time ambient temperature is greater than or equal to the preset temperature threshold, the control device records the preset power limit relationship according to the map table, finds the power limit value corresponding to the real-time ambient temperature, and performs power limit control on the fuel cell system according to the power limit value.

[0054] Step 130: During the process of dynamically controlling the first limiting power of the fuel cell system, if the real-time ambient temperature of the fuel cell system continues to be lower than the preset temperature threshold for more than a first time, based on the first relationship of the current limiting power value of the fuel cell system, the first limiting power of the fuel cell system is dynamically controlled, and the preset power limiting relationship is corrected until the real-time ambient temperature of the fuel cell system is greater than or equal to the preset temperature threshold.

[0055] Exemplarily, while limiting the power of the fuel cell system according to the preset power limit relationship, the temperature of the air inlet of the radiator of the fuel-electric system is monitored in real time. In the process of dynamically controlling the power limit of the fuel cell system, if the real-time ambient temperature of the fuel cell system gradually decreases to below the preset temperature threshold, and continues to be below the preset temperature threshold for more than the first time, the fuel cell system is considered to be stable.

[0056] In some embodiments of the present invention, based on the first relationship of the current limit power value of the fuel cell system, dynamically controlling the first limit power of the fuel cell system and correcting the preset power limit relationship include:

[0057] Based on a first relationship of a current limit power value of the fuel cell system, increasing a first limit power of the fuel cell system every fifth time until a real-time ambient temperature of the fuel cell system is greater than or equal to a preset temperature threshold;

[0058] Among them, when the limit power of the fuel cell system is increased to a fifth time and the real-time ambient temperature of the fuel cell system remains lower than a preset temperature threshold within the fifth time range, the preset power limit relationship is corrected according to the current ambient temperature value and the current limit power value of the fuel cell system.

[0059] In some embodiments of the present invention, Figure 2 As shown, in the process of dynamically controlling the power limit of the fuel cell system, if the real-time ambient temperature of the fuel cell system continues to be lower than the preset temperature threshold for more than a first time, the power limit of the fuel cell system is increased every 5 minutes, each time by x% of the current power limit value, and a determination is made every 300 seconds whether over-temperature is triggered after the power limit value is increased.

[0060] Exemplarily, when the real-time ambient temperature is greater than or equal to the preset temperature threshold, the control device records the preset power limit relationship according to the map table, finds that the power limit value corresponding to the real-time ambient temperature is value A, and controls the fuel cell system to limit the power to value A. When it is detected that the real-time ambient temperature is continuously lower than the preset temperature threshold for more than the first time, the fuel cell system is controlled to limit the power to value B, B = A + x% A.

[0061] If the real-time ambient temperature is greater than or equal to the preset temperature threshold within 5 minutes after the power limit is increased to value B, the fuel cell system is still controlled to limit the power to the power limit value of the previous round of increase, that is, value A. In this case, the preset power limit relationship remains unchanged.

[0062] If the real-time ambient temperature is not greater than or equal to the preset temperature threshold within 5 minutes after the power limit is increased to value B, the power limit value corresponding to the current real-time ambient temperature in the preset power limit relationship is corrected to value B, and the limited power value continues to be increased by x% of the current limited power value, that is, the power limit value is increased to (B+x%B) value, until the real-time ambient temperature is greater than or equal to the preset temperature threshold within 5 minutes after the power is increased.

[0063] The adaptive control method of fuel cell power provided in this embodiment limits the power of the vehicle by means of the power limit range of the ambient temperature calibrated by the preset power limit relationship when the real-time ambient temperature of the vehicle fuel cell system exceeds the limit. During the process of vehicle power limitation, if the real-time ambient temperature of the fuel cell system continues to be lower than the preset temperature threshold for more than the first time, the technical solution of the present application can dynamically adjust the power limit according to the environment in which the vehicle is located, gradually increase the power limit until the maximum power limit of the fuel cell system is reached, which not only ensures that the fuel cell is used without over-temperature failure, but also maximizes the power output required for driving, avoids interruption or creeping of driving, and improves the flexibility of power control of the fuel cell.

[0064] Embodiment 2, Figure 3 The flowchart of an embodiment of the method for adaptively controlling the power of a fuel cell of the present invention is shown, and the method is executed by an adaptive control device for the power of a fuel cell. Figure 3 As shown, the method comprises the following steps:

[0065] Step 210: Obtain the real-time ambient temperature of the fuel cell system.

[0066] Preferably, the ambient temperature is detected by an ambient temperature sensor installed on the air inlet side of the fuel-electric system radiator. The ambient temperature sensor can detect the ambient air temperature, and the control device monitors the temperature of the air inlet of the fuel-electric system radiator in real time.

[0067] Step 220: When the real-time ambient temperature is greater than or equal to a preset temperature threshold, dynamically controlling a first limited power of the fuel cell system based on the real-time ambient temperature and a preset power limit relationship until the real-time ambient temperature is lower than the preset temperature threshold;

[0068] The preset power limit relationship calibrates the power limit range of the target ambient temperature; the target ambient temperature is a range of several ambient temperatures exceeding a preset temperature threshold.

[0069] In some embodiments of the present invention, dynamically controlling the power limit of the fuel cell system based on the real-time ambient temperature and the preset power limit relationship includes:

[0070] Based on a preset power limit relationship, determining a power limit range corresponding to the real-time ambient temperature;

[0071] The power limit of the fuel cell system is controlled to be within a corresponding power limit range.

[0072] Specifically, the preset temperature threshold is the size of the temperature limit. When the real-time ambient temperature is greater than or equal to the preset temperature threshold, it means that the fuel cell system is over-temperature and needs to be cooled.

[0073] In some embodiments of the present invention, the power limit range for several ambient temperatures exceeding a preset temperature threshold is calibrated according to the vehicle radiator capacity.

[0074] Preferably, the control device uses a map table to record the preset power limit relationship, each ambient temperature corresponds to a power limit value, and the higher the ambient temperature, the lower the power limit value. When the real-time ambient temperature is greater than or equal to the preset temperature threshold, the control device records the preset power limit relationship according to the map table, finds the power limit value corresponding to the real-time ambient temperature, and performs power limit control on the fuel cell system according to the power limit value.

[0075] Step 230: If the power of the fuel cell system is controlled to exceed the second time within the corresponding power limit range, and the real-time ambient temperature is still greater than or equal to the preset temperature threshold, then based on the second relationship of the current limit power value of the fuel cell system, the second limit power of the fuel cell system is dynamically controlled, and the preset power limit relationship is corrected until the real-time ambient temperature is lower than the preset temperature threshold.

[0076] In some embodiments of the present invention, based on the second relationship of the current limit power value of the fuel cell system, dynamically controlling the second limit power of the fuel cell system and correcting the preset power limit relationship includes:

[0077] Based on the second relationship of the current limiting power value of the fuel cell system, the second limiting power of the fuel cell system is reduced once every third time period until the real-time ambient temperature of the fuel cell system is less than a preset temperature threshold, and then the preset power limiting relationship is corrected according to the current ambient temperature value of the fuel cell system and the current limiting power value.

[0078] In some embodiments of the present invention, if the power of the fuel cell system is limited to be less than or equal to the first power value for more than a fourth time and the real-time ambient temperature is still greater than or equal to a preset temperature threshold, the fuel cell system is controlled to shut down and an alarm notification is issued.

[0079] In some embodiments of the present invention, Figure 4As shown, while limiting the power of the fuel cell system according to the preset power limit relationship, the temperature of the air inlet of the radiator of the fuel-electric system is monitored in real time. In the process of dynamically controlling the limited power of the fuel cell system, if the power of the fuel cell system is controlled to exceed the second time in the corresponding power limit range, and the real-time ambient temperature is still greater than or equal to the preset temperature threshold, the limited power of the fuel cell system is reduced once every third time, and the current limited power value is reduced by y% each time, and it is determined once every 300 seconds whether the real-time ambient temperature is less than the preset temperature threshold after the limited power value is reduced, and the preset power limit relationship is corrected according to the current ambient temperature value and the current limited power value of the fuel cell system.

[0080] Exemplarily, when the real-time ambient temperature is greater than or equal to the preset temperature threshold, the control device records the preset power limit relationship according to the map table, finds that the power limit value corresponding to the real-time ambient temperature is value A, and controls the fuel cell system to limit the power to value A. If the power limit of the fuel cell system is controlled to value A for more than a second time, and the real-time ambient temperature is still greater than or equal to the preset temperature threshold, the control device controls the fuel cell system to limit the power to value C, C = Ay% A. The control device corrects the power limit value corresponding to the current real-time ambient temperature in the preset power limit relationship to value C.

[0081] If the power limit of the fuel cell system is controlled to be C value for more than the third time, and the real-time ambient temperature is still greater than or equal to the preset temperature threshold, the limited power value will continue to be reduced by y% of the current limited power value, that is, the power limit value will be reduced to (Cy%C) value, until the real-time ambient temperature is less than the preset temperature threshold within the third time after the power reduction, or the power of the fuel cell system is limited to be less than or equal to the first power value for more than the fourth time, and the real-time ambient temperature is still greater than or equal to the preset temperature threshold, the fuel cell system will be controlled to shut down, and an alarm notification will be issued.

[0082] like Figure 5As shown, when the fuel cell system is in the locked state, the control device turns on the low voltage to enter the unlocked state. When the fuel cell system is in the unlocked state, the control device turns off the low voltage to return to the locked state, and turns on the high voltage to enter the standby state. When the fuel cell system is in the standby state, the control device turns off the high voltage to return to the unlocked state; when the control device receives the start signal, the fuel cell system is controlled to start. If a normal shutdown signal or a serious fault signal is received during startup, the fuel cell system is controlled to shut down without purging, and the heat dissipation core is cooled naturally. If the start preparation of the control fuel cell system is completed, the fuel cell system is operated. During the operation of the fuel cell system, if a normal shutdown signal is received, the fuel cell system is controlled to shut down for purging, and the fuel-electric system is set to run at idle power. At the same time, the speed of the cooling fan of the radiator is increased to a certain value for purging, and the coolant temperature of the fuel cell system is quickly reduced to the set value, so that the heat dissipation core is cooled; if a serious fault signal is received, the fuel cell system is controlled to shut down without purging, and the heat dissipation core is cooled naturally.

[0083] In the process of vehicle power limitation, in the adaptive control method of fuel cell power provided in the present embodiment, if the power of the fuel cell system is controlled to exceed the second time within the corresponding power limitation range, and the real-time ambient temperature is still greater than or equal to the preset temperature threshold, the technical solution of the present application can dynamically adjust the power limitation according to the environment in which the vehicle is located, and gradually reduce the power limitation until it reaches the appropriate power limit of the fuel cell system, thereby further ensuring that the fuel cell is used without over-temperature failure and improving the flexibility of the power control of the fuel cell.

[0084] Embodiment 3, Figure 6 FIG. 1 is a schematic diagram showing a structure of an embodiment of a fuel cell power adaptive control device of the present invention; Figure 6 As shown, the device 300 includes: a temperature measurement module 310, an over-temperature power limiting module 320 and an adaptive adjustment module 330;

[0085] The temperature measurement module 310 is used to obtain the real-time ambient temperature of the fuel cell system;

[0086] The over-temperature power limiting module 320 is used to dynamically control the first limited power of the fuel cell system based on the real-time ambient temperature and the preset power limiting relationship when the real-time ambient temperature is greater than or equal to the preset temperature threshold, until the real-time ambient temperature is lower than the preset temperature threshold;

[0087] Wherein, the preset power limit relationship calibrates the power limit range of the target ambient temperature; the target ambient temperature is a range of ambient temperatures exceeding a preset temperature threshold;

[0088] The adaptive adjustment module 330 is used to dynamically control the first limiting power of the fuel cell system and correct the preset power limiting relationship based on a first relationship with a current limiting power value of the fuel cell system during the process of dynamically controlling the first limiting power of the fuel cell system, if the real-time ambient temperature of the fuel cell system continues to be lower than a preset temperature threshold for more than a first time, until the real-time ambient temperature of the fuel cell system is greater than or equal to the preset temperature threshold.

[0089] In an optional manner, the ambient temperature is detected by an ambient temperature sensor installed on the air inlet side of the radiator of the fuel-electric system.

[0090] In an optional manner, dynamically controlling the power limit of the fuel cell system based on the real-time ambient temperature and the preset power limit relationship includes:

[0091] Based on a preset power limit relationship, determining a power limit range corresponding to the real-time ambient temperature;

[0092] The power limit of the fuel cell system is controlled to be within a corresponding power limit range.

[0093] In an optional manner, if the power of the fuel cell system is controlled to exceed a second time within the corresponding power limit range and the real-time ambient temperature is still greater than or equal to a preset temperature threshold, the second limit power of the fuel cell system is dynamically controlled based on a second relationship of the current limit power value of the fuel cell system, and the preset power limit relationship is corrected until the real-time ambient temperature is lower than the preset temperature threshold.

[0094] In an optional manner, based on the second relationship of the current limit power value of the fuel cell system, dynamically controlling the second limit power of the fuel cell system and correcting the preset power limit relationship includes:

[0095] Based on the second relationship of the current limiting power value of the fuel cell system, the second limiting power of the fuel cell system is reduced once every third time period until the real-time ambient temperature of the fuel cell system is less than a preset temperature threshold, and then the preset power limiting relationship is corrected according to the current ambient temperature value of the fuel cell system and the current limiting power value.

[0096] In an optional manner, dynamically controlling the limit power of the fuel cell system based on the second relationship of the current limit power value of the fuel cell system further includes:

[0097] If the power of the fuel cell system is limited to be less than or equal to the first power value for more than a fourth time, and the real-time ambient temperature is still greater than or equal to the preset temperature threshold, the fuel cell system is controlled to shut down and an alarm notification is issued.

[0098] In an optional manner, based on the first relationship of the current limit power value of the fuel cell system, dynamically controlling the first limit power of the fuel cell system and correcting the preset power limit relationship include:

[0099] Based on a first relationship of a current limit power value of the fuel cell system, increasing a first limit power of the fuel cell system every fifth time until a real-time ambient temperature of the fuel cell system is greater than or equal to a preset temperature threshold;

[0100] Among them, when the limit power of the fuel cell system is increased to a fifth time and the real-time ambient temperature of the fuel cell system remains lower than a preset temperature threshold within the fifth time range, the preset power limit relationship is corrected according to the current ambient temperature value and the current limit power value of the fuel cell system.

[0101] As for the device embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0102] The adaptive control device for fuel cell power provided by the present application uses an over-temperature power limiting module to limit the power of the vehicle by means of the power limiting range of the ambient temperature calibrated by the preset power limiting relationship when the real-time ambient temperature of the vehicle fuel cell system exceeds the limit. During the process of vehicle power limiting, if the real-time ambient temperature of the fuel cell system continues to be lower than the preset temperature threshold for more than the first time, the present application uses an adaptive adjustment module to dynamically adjust the power limit according to the environment in which the vehicle is located, gradually increase the power limit until the maximum power limit of the fuel cell system is reached, which not only ensures that the fuel cell is used without over-temperature failure, but also maximizes the power output required for driving, avoids interruption or creeping of driving, and improves the flexibility of power control of the fuel cell.
