The catalyst is often easily adsorbed by pollutants such as carbon monoxide, nitrogen oxides, and sulfides in the air flowing into the cathode system and is easily oxidized by the air flowing into the cathode system.

[0040] In order to make the purpose, technical solution and beneficial effects of this application clearer, the technical solution in the embodiment of this application will be clearly and completely described below in conjunction with the drawings in the embodiment of this application. Obviously, the described embodiment is only a part of the embodiment of this application, not all the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] In order to facilitate those skilled in the art to better understand the present application, the technical terms involved in the present application are briefly introduced below.

[0042] The power system is a system that provides power for acceleration, deceleration, starting and stopping of new energy vehicles. In new energy vehicles, the power system includes at least an electric motor, a battery pack and a fuel cell system.

[0043] The vehicle required power is the power required for new energy vehicles to perform actions such as acceleration, deceleration, starting and stopping.

[0044] The actual output power is the power actually output by the fuel cell system during the activation process.

[0045] The target compensation power is the actual compensation power of the battery pack when the actual output power of the fuel cell system does not meet the requested power of the vehicle;

[0046] The activation flag is a flag used to characterize whether the fuel cell system meets the activation conditions. In the present application, when the fuel cell system meets the activation conditions, the activation flag is set to the target character, and when the fuel cell system does not meet the activation conditions, the activation flag is set to a character other than the target character. For example, when the fuel cell system meets the activation conditions, the activation flag is set to "1", and when the fuel cell system does not meet the activation conditions, the activation flag is set to "0". For another example, when the fuel cell system meets the activation conditions, the activation flag is set to "a", and when the fuel cell system does not meet the activation conditions, the activation flag is set to "b", etc.

[0047] It should be noted that the terms "first", "second", etc. mentioned in this application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.

[0048] After introducing the technical terms involved in this application, the application scenarios and design concepts of this application are briefly introduced.

[0049] In new energy vehicles, the performance of the fuel cell system will be reduced after long-term operation. In order to restore the performance of the fuel cell system, the fuel cell system is usually activated by offline activation, or by active activation after the fuel cell system fails to start. Both activation methods will affect the normal operation of new energy vehicles, thereby adversely affecting the driving experience of new energy vehicles.

[0050] To this end, during the operation of the new energy vehicle, the present application determines that the fuel cell system meets the activation conditions based on the operating status information of the fuel cell system, and when it is determined that the battery pack meets the power compensation conditions based on the charge state information of the battery pack, the activation operation is performed on the fuel cell system. The operating status information of the fuel cell system and the charge state information of the battery pack can be used to accurately determine the activation timing of the fuel cell system, thereby realizing the active activation of the fuel cell system during the operation of the new energy vehicle while improving the timeliness of the activation of the fuel cell system. Moreover, during the activation operation of the fuel cell system, when it is determined that the actual output power of the fuel cell system does not meet the requested power of the whole vehicle, the target compensation power of the battery pack is determined based on the actual output power and the requested power of the whole vehicle, and the battery pack is controlled to output the target compensation power. During the activation of the fuel cell system, the battery pack can be used for power compensation to provide sufficient power for the whole vehicle, thereby effectively avoiding the problem that the cathode system is insufficient in gas during the activation of the fuel cell system, which makes it difficult to meet the requested power demand of the whole vehicle and then affects the normal operation of the new energy vehicle. In addition, the non-sensing activation of the fuel cell system during the operation of the new energy vehicle can be realized, and the driving experience of the new energy vehicle during the activation of the fuel cell system can be improved.

[0051] After introducing the application scenarios and design ideas of the present application, the technical solutions provided by the present application are described in detail below.

[0052] The present application provides a fuel cell system activation control method, which can be applied to a fuel cell control device in a fuel cell system, such as a fuel cell controller (Fuel cell Control Unit, FCU) in a fuel cell system. For details, see Figure 1As shown, the general process of the fuel cell system activation control method provided in the embodiment of the present application is as follows:

[0053] Step 101: During the operation of the new energy vehicle, when it is determined based on the operating status information of the fuel cell system that the fuel cell system meets the activation condition and based on the charge status information of the battery pack that the battery pack meets the power compensation condition, an activation operation is performed on the fuel cell system.

[0054] In actual applications, during the operation of new energy vehicles, the operating status information of the fuel cell system can be monitored in real time or periodically, such as real-time or periodic monitoring of the operating time of the fuel cell system after the last activation operation was performed on the fuel cell system and the health of the fuel cell system. Specifically, the operating time of the fuel cell system can be determined based on the timing time of the timer, and the health of the fuel cell system can be determined based on the attenuation degree of the fuel cell system during operation. For example, based on the difference between the calibrated output power and the actual output power of the fuel cell system under various working conditions within a set time range, the attenuation degree of the fuel cell system during operation is calculated, and based on the attenuation degree and operating parameters of the fuel cell system during operation, the health of the fuel cell system is calculated. For example, based on the calibrated output power, actual output power and operating parameters of the fuel cell system under various working conditions within a set time range, a health detection model is used to obtain the health of the fuel cell system, etc., so that it can be determined whether the fuel cell system meets the activation conditions based on the operating time of the fuel cell system and the health of the fuel cell system. Specifically, but not limited to, the following methods can be used:

[0055] Method 1: directly determine that the fuel cell system meets the activation condition when it is detected that the health level of the fuel cell system is not higher than the health level threshold and the operating time of the fuel cell system is not lower than the operating time threshold, otherwise, determine that the fuel cell system does not meet the activation condition.

[0056] Method 2: When it is detected that the health of the fuel cell system is not higher than the health threshold and the operating time of the fuel cell system is not lower than the operating time threshold, the activation flag is set to the target character. When an activation judgment is required, whether the fuel cell system meets the activation conditions is detected based on the activation flag, that is, when the activation flag is detected to be the target character, the fuel cell system is determined to meet the activation conditions, otherwise, the fuel cell system is determined not to meet the activation conditions. For example, when the activation flag is detected to be "1", the fuel cell system is determined to meet the activation conditions, and when the activation flag is detected to be "0", the fuel cell system is determined not to meet the activation conditions. Thus, by setting the activation flag, the problem of affecting the efficiency of activation judgment due to the need to re-detect the health and operating time during asynchronous operation can be effectively solved.

[0057] In the embodiment of the present application, there is no sequence between the step of determining whether the health level of the fuel cell system is not higher than the health level threshold and the step of determining whether the operating time of the fuel cell system is not lower than the operating time threshold. It is possible to first determine whether the health level of the fuel cell system is not higher than the health level threshold, and then determine whether the operating time of the fuel cell system is not lower than the operating time threshold. It is also possible to first determine whether the operating time of the fuel cell system is not lower than the operating time threshold, and then determine whether the health level of the fuel cell system is not higher than the health level threshold. As long as it is determined that the health level of the fuel cell system is not higher than the health level threshold and the operating time of the fuel cell system is not lower than the operating time threshold, it can be determined that the fuel cell system meets the activation conditions. In order to ensure that during the activation process of the fuel cell system In order to provide sufficient power for new energy vehicles during the process, in addition to detecting whether the fuel cell system meets the activation conditions, it is also necessary to detect whether the charge state information of the battery pack meets the power compensation conditions, such as detecting whether the remaining battery capacity of the battery pack meets the power compensation conditions. Specifically, when it is detected that the remaining battery capacity of the battery pack is not less than the remaining battery capacity threshold, the battery pack is determined to meet the power compensation conditions. Otherwise, the battery pack is determined to not meet the power compensation conditions. It is worth mentioning that when it is detected that the remaining battery capacity of the battery pack is lower than the remaining battery capacity threshold, that is, when it is determined that the battery pack does not meet the power compensation conditions, the battery pack can be controlled to charge until it is determined that the remaining battery capacity of the battery pack is not less than the remaining battery capacity threshold, at which time the battery pack is determined to meet the power compensation conditions. In practical applications, the battery remaining capacity threshold can be set to a larger value, such as 95%, 98%, 100%, etc., so as to ensure that sufficient power can be provided to the new energy vehicle during the activation process of the fuel cell system. After determining that the fuel cell system meets the activation conditions based on the operating status information of the fuel cell system and that the battery pack meets the power compensation conditions based on the charge state information of the battery pack, the activation operation can be performed on the fuel cell system. Specifically, when performing the activation operation on the fuel cell system, the following methods can be used but are not limited to:

[0058] First, based on the health of the fuel cell system, the activation times of the fuel cell system are determined. Specifically, based on the pre-calibrated correspondence between the health and activation times, the activation times corresponding to the health of the fuel cell system can be determined as the activation times of the fuel cell system.

[0059] Then, the fuel cell system is activated according to the activation times; wherein, when the fuel cell system is activated according to the activation times, the following methods may be used but are not limited to:

[0060] Step 1011, controlling the fuel cell system to operate at a maximum rated power.

[0061] Step 1012, after determining that the fuel cell system is stably operating at the maximum rated power, gradually reduce the cathode air stoichiometric ratio of the fuel cell system to the target air stoichiometric ratio; wherein, as the cathode air stoichiometric ratio is gradually reduced, the single cell voltage continues to decrease.

[0062] Step 1013, when it is detected that the lowest cell voltage among the cell voltages of the fuel cell stack is less than the voltage threshold, the target air stoichiometric ratio is restored to the cathode air stoichiometric ratio; wherein, as the cathode air stoichiometric ratio is restored, the cell voltage is restored.

[0063] Step 1014, after detecting that the voltages of all cells in the fuel cell stack have recovered, it is determined that an activation operation is completed, and the count value of the counter is controlled to be increased by 1. When it is determined that the count value of the counter has not reached the number of activation times, it returns to step 1011. When it is determined that the count value of the counter has reached the number of activation times, it is determined that the activation operation of the fuel cell system is completed.

[0064] In an embodiment of the present application, in order to improve the activation efficiency and activation effect of the fuel cell system, during the activation operation of the fuel cell system according to the activation number, the health of the fuel cell system can also be monitored in real time or periodically, and the activation number can be updated based on the monitored health of the fuel cell system. Specifically, based on the correspondence between the pre-calibrated health and the activation number, the activation number of the fuel cell system can be updated to the activation number corresponding to the monitored health of the fuel cell system, thereby achieving accurate control of the activation number of the fuel cell system and improving the activation efficiency and activation effect of the fuel cell system.

[0065] Step 102: During the activation operation of the fuel cell system, when it is determined that the actual output power of the fuel cell system does not meet the vehicle's requested power, the target compensation power of the battery pack is determined based on the actual output power and the vehicle's requested power, and the battery pack is controlled to output the target compensation power.

[0066] In the embodiment of the present application, in order to achieve non-sensing activation of the fuel cell system during the operation of the new energy vehicle, the battery pack can also be used for power compensation during the activation operation of the fuel cell system. That is, during the activation operation of the fuel cell system, when it is determined that the actual output power of the fuel cell system does not meet the requested power of the whole vehicle, the target compensation power of the battery pack is determined based on the actual output power and the requested power of the whole vehicle, and the battery pack is controlled to output the target compensation power. Specifically, the power difference between the actual output power of the fuel cell system and the requested power of the whole vehicle can be determined as the target compensation power of the battery pack, so that the actual output power of the fuel cell system during the activation process is compensated by controlling the battery pack to output the target compensation power, and then sufficient power can be provided to the whole vehicle during the activation process of the fuel cell system, effectively avoiding the problem that the cathode system is insufficient in gas during the activation process of the fuel cell system, which makes it difficult to meet the requested power demand of the whole vehicle and then affects the normal operation of the new energy vehicle. Therefore, non-sensing activation of the fuel cell system during the operation of the new energy vehicle can be achieved, and the driving experience of the new energy vehicle during the activation process of the fuel cell system is improved.

[0067] In addition, in the embodiment of the present application, during the activation operation of the fuel cell system, when it is determined that the activation termination condition is met, the activation operation of the fuel cell system is controlled to be terminated, wherein the activation termination condition is any one of the following conditions: receiving a shutdown command, the remaining battery capacity of the battery pack does not meet the target compensation power, the fuel cell system fails, or an emergency occurs. Further, after the activation operation of the fuel cell system is controlled to be terminated, an activation termination mark can be generated for the activation operation being performed before the activation operation is terminated, so that when it is determined that the activation recovery condition is met, the activation operation of the fuel cell system is continued based on the activation termination mark, and the activation recovery condition corresponding to the activation termination condition is any one of the following conditions: receiving a power-on command, the remaining battery capacity of the battery pack is not less than the remaining battery capacity threshold, the fuel cell system contacts a fault, or the emergency is released, so that the activation operation can be adaptively performed according to the actual working conditions during the operation of the new energy vehicle, thereby improving the flexibility of the activation of the fuel cell system. In addition, after controlling the termination of the activation operation on the fuel cell system, the fuel cell system can also be controlled to perform corresponding response operations according to different activation termination conditions. For example, during the activation operation on the fuel cell system, when a shutdown command is received, or when it is detected that the remaining battery capacity of the battery pack does not meet the target compensation power, the activation operation on the fuel cell system is terminated, and the fuel cell system is controlled to restore normal power response. For another example, during the activation operation on the fuel cell system, when a system failure or an emergency situation is detected in the fuel cell system, the activation operation on the fuel cell system is terminated, and the fuel cell system is controlled to respond to the system failure or emergency situation.

[0068] The fuel cell system activation control method provided in the embodiment of the present application is further described in detail below. Figure 2 As shown, the specific process of the fuel cell system activation control method provided in the embodiment of the present application is as follows:

[0069] Step 201: During the operation of the new energy vehicle, real-time or periodic monitoring is performed on the operation time of the fuel cell system after the last activation operation is performed on the fuel cell system and the health of the fuel cell system.

[0070] Step 202: Determine whether the health level of the fuel cell system is not higher than the health level threshold and the operating time of the fuel cell system is not lower than the operating time threshold. If so, execute step 203; if not, return to step 201.

[0071] Step 203: Determine whether the remaining battery capacity of the battery pack is not less than the remaining battery capacity threshold, if so, execute step 205, if not, execute step 204.

[0072] Step 204 : Control charging of the battery pack until it is determined that the remaining battery capacity of the battery pack is not less than a remaining battery capacity threshold, and then proceed to step 205 .

[0073] Step 205: performing activation operations of steps 2051 to 2058 on the fuel cell system;

[0074] Step 2051: Determine the activation times of the fuel cell system based on the health of the fuel cell system.

[0075] Step 2052: Control the fuel cell system to operate at the maximum rated power.

[0076] Step 2053: After determining that the fuel cell system is stably operating at the maximum rated power, gradually reduce the cathode air stoichiometric ratio of the fuel cell system to the target air stoichiometric ratio; wherein, as the cathode air stoichiometric ratio is gradually reduced, the single cell voltage continues to decrease.

[0077] Step 2054: When it is detected that the lowest cell voltage among the cell voltages of the fuel cell stack is less than the voltage threshold, the target air stoichiometric ratio is restored to the cathode air stoichiometric ratio; wherein, as the cathode air stoichiometric ratio is restored, the cell voltage is restored.

[0078] Step 2055: After detecting that the voltages of all cells in the fuel cell stack have recovered, it is determined that one activation operation is completed, and the count value of the counter is increased by 1.

[0079] Step 2056: Monitor the current health of the fuel cell system, and based on a pre-calibrated correspondence between the health and activation times, update the activation times of the fuel cell system to the activation times corresponding to the monitored health of the fuel cell system.

[0080] Step 2057: Determine whether the count value of the counter reaches the updated activation times. If so, execute step 2058; if not, return to step 2052.

[0081] Step 2058: Determine that the activation operation of the fuel cell system is completed.

[0082] Step 206: During the activation process of executing steps 2051 to 2058 on the fuel cell system, if a vehicle power request is received, determine whether the current actual output power of the fuel cell system meets the vehicle request power corresponding to the vehicle power request. If so, execute step 207; if not, execute step 208.

[0083] Step 207: Control the fuel cell system to maintain the current actual output power.

[0084] Step 208: Determine the target compensation power of the battery pack based on the current actual output power of the fuel cell system and the vehicle request power corresponding to the vehicle power request, control the fuel cell system to maintain the current actual output power, and control the battery pack to output the target compensation power for power compensation.

[0085] Step 209: During the process of executing the activation operation of step 2051 to step 2058 on the fuel cell system, when it is determined that the activation termination condition is met, the activation operation on the fuel cell system is terminated, and the fuel cell system is controlled to perform a corresponding response operation, wherein the activation termination condition is any one of receiving a shutdown command, the remaining battery capacity of the battery pack does not meet the target compensation power, the fuel cell system fails, or an emergency occurs.

[0086] Step 210: Generate an activation termination mark for the activation step being executed before the activation operation is terminated, and when it is determined that the activation recovery condition is met, continue to perform the activation operation on the fuel cell system based on the activation termination mark, wherein the activation recovery condition is any one of the following conditions: receiving a power-on command, the remaining battery capacity of the battery pack is not less than the remaining battery capacity threshold, and the fuel cell system is free from faults or emergency situations.

[0087] Based on the above embodiments, the present application also provides a fuel cell system activation control device, see Figure 3 As shown, the fuel cell system activation control device 300 provided in the embodiment of the present application at least includes:
