Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicles, and more particularly, to a method, apparatus, controller, vehicle, and medium for distributing output power. Background Art

[0002] Among various types of new energy vehicles, fuel cell vehicles have broad development prospects due to their advantages of high efficiency and zero emissions. The power core of a fuel cell vehicle is a fuel cell system. However, the dynamic response of the fuel cell system is slow. Therefore, a storage battery is often configured as an auxiliary power source in a fuel cell vehicle. The output power of the vehicle can be provided jointly by the fuel cell system and the storage battery, so that the output power of the vehicle can adapt to the changing driving conditions of the vehicle.

[0003] An energy management strategy can be configured in a fuel cell vehicle. The energy management strategy can distribute the output power of the whole vehicle among different power sources to keep the performance and operation efficiency of the whole vehicle optimal. Currently, the energy management strategy usually distributes the output power based on the state of the storage battery. For example, when distributing the output power, the equivalent fuel consumption of the storage battery is considered to optimize the fuel consumption of the whole vehicle, or the state of charge of the storage battery is maintained within a reasonable range to extend the life of the storage battery.

[0020] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not used to limit the protection scope of the present disclosure.

[0021] In the description of the embodiments of the present disclosure, the term "including" and its similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "an embodiment" or "the embodiment" should be understood as "at least one embodiment". Terms such as "first", "second", etc. may refer to different or the same objects. There may also be other explicit and implicit definitions below.

[0022] In the embodiments of the present disclosure, the vehicle may include, but is not limited to, sedans, trucks, electric vehicles, buses, airplanes, drones, recreational vehicles, construction equipment, intelligent robots, etc. that have a fuel cell system and a storage battery. The embodiments of the present disclosure are not particularly limited. For the convenience of description, in the embodiments of the present disclosure, an automobile is taken as an example to describe the method provided by the present disclosure. It should be understood that this should not be a limitation on the embodiments of the present disclosure.

[0023] As described above, when allocating the output power of a fuel cell vehicle, the state of the storage battery is usually considered. The inventors of the present disclosure have found through research that the state of the fuel cell system also has a great impact on the performance and operating efficiency of the entire vehicle. For example, if the fuel cell system operates at a low load, more of the energy generated by the fuel cell system will be dissipated in the form of heat, which will increase the fuel consumption of the entire vehicle and reduce the operating efficiency of the entire vehicle. Another example is that if the fuel cell system operates at a low load in a low-pressure environment at a high altitude, in order to make the cathode of the fuel cell system reach the normal operating pressure, the air compressor of the fuel cell system may consume more energy and may also experience surging, which will damage the air compressor and thus affect the performance of the entire vehicle. Therefore, if the state of the fuel cell system is not considered when allocating the output power, it may not be possible to keep the vehicle in the state of the highest operating efficiency, and may even reduce the service life of the fuel cell system and affect the performance of the entire vehicle.

[0024] To this end, an embodiment of the present disclosure provides a solution for allocating output power. In the embodiment of the present disclosure, a requested value of the output power of the vehicle and a power distribution parameter of the vehicle can be obtained. The power distribution parameter can include at least one of an environmental pressure value of the environment where the vehicle is located and a heat dissipation value of the fuel cell system. The embodiment of the present disclosure can allocate the requested value of the output power between the fuel cell system and the storage battery based on the power distribution parameter.

[0025] In this way, it is possible to consider the state of the fuel cell system of the vehicle when allocating the output power. For example, the heat dissipation of the fuel cell system can be considered, so that the fuel cell system can operate at high efficiency. Another example is that the environmental pressure that affects the performance of the fuel cell system can be considered, so that it is possible to avoid the fuel cell system being in a low-load state when the environmental pressure is low, in order to avoid damage to the fuel cell system. In this way, the power distribution between the fuel cell system and the storage battery can be made more balanced and reasonable, so that the performance and efficiency of the entire vehicle can be optimized.

[0026] Figure 1 A schematic diagram of an example vehicle 100 in which multiple embodiments of the present disclosure can be implemented is shown. As Figure 1As shown, in vehicle 100, components such as a controller 110, a fuel cell system 120, a storage battery 130, and a motor 140 may be included. Among them, the controller 110 may be a device for controlling the output power of the fuel cell system 120 and the storage battery 130 in the vehicle 100, including but not limited to a computer, a processor, a chip, a chip system, etc. configured in the vehicle 100. In some embodiments, the controller 110 may be the controller of the vehicle's power management system (PMS). In some embodiments, the controller 110 is a vehicle control unit (VCU) configured in the vehicle.

[0027] The fuel cell system 120 and the storage battery 130 are the driving force power sources of the vehicle 100. They can convert the chemical energy of reactants (including hydrogen and oxygen) into electrical energy and heat energy through an electrochemical reaction, thereby driving the motor 140. The storage battery 130 can store the additional electrical energy provided by the fuel cell system 120, and the storage battery 130 can also supply power to the motor 140. The motor 140 can convert electrical energy into mechanical energy, thereby rotating the driving wheels of the vehicle 100 and enabling the vehicle to travel on the road. The motor 140 can be driven by the fuel cell system 120 or by the storage battery 130. In some embodiments, the motor 140 is driven jointly by the fuel cell system 120 and the storage battery 130. In some embodiments, the controller 110 may obtain the requested value of the driving force of the vehicle, and on this basis, determine the requested value of the output power of the vehicle. The controller 110 may distribute the requested value of the output power between the fuel cell system 120 and the storage battery 130, thereby controlling the fuel cell system 120 and the storage battery 130 to jointly drive the motor 140. In some embodiments, the controller 110 may obtain the power distribution parameters from the fuel cell system 120 and on this basis distribute the output power of the fuel cell system 120 and the storage battery 130.

[0028] Figure 2 A schematic diagram of a fuel cell system 200 in some embodiments of the present disclosure is shown. Figure 2 The fuel cell system 200 in [reference] may correspond to the fuel cell system 120 in the vehicle 100. Figure 2, the fuel cell system 200 may include a fuel cell stack 201. The fuel cell stack 201 may include a cathode 202 and an anode 203. Oxygen in the cathode 202 and hydrogen in the anode 203 may undergo an electrochemical reaction on the membrane electrode of the fuel cell stack 201 to generate electrical energy. The fuel cell system 200 may further include a direct current / direct current (DC / DC) converter 204. The DC / DC converter 204 may adjust the electrical energy output by the fuel cell stack 201 and convert the varying voltage provided by the fuel cell stack 201 into a stable output voltage. It should be understood that Figure 2 the fuel cell stack 201 in is only a schematic illustration for explanation purposes. In some embodiments, the fuel cell stack 201 may include a plurality of monolithic cells connected in series, and each monolithic cell may include a cathode, an anode, and a membrane electrode.

[0029] The fuel cell system 200 may further include a hydrogen injector 205, a water separator 206, a hydrogen circulation pump 207, a drain valve 208, and a hydrogen discharge valve 209. Among them, the hydrogen injector may supply hydrogen from the hydrogen storage system to the anode 203 and control the hydrogen pressure and flow rate. The water separator 206 may separate the liquid water in the gas at the outlet of the anode 203 and discharge the liquid water through the drain valve 208. The hydrogen discharge valve 209 may also be referred to as a purge valve and may discharge the impurity gas (such as nitrogen) when the concentration of the impurity gas in the anode 203 becomes high. The hydrogen circulation pump 207 may circulate the unreacted hydrogen at the outlet of the anode 203 to the inlet of the anode 203.

[0030] The fuel cell system 100 may further include a filter 210, an air compressor 211, an intercooler 212, an upstream shut-off valve 213, an exhaust throttle valve 214, a bypass valve 215, and a tailpipe muffler 216. Among them, the filter 210 may be referred to as an air filter and may filter out particulate impurities in the air to avoid clogging the pipelines of the fuel cell system 200. The air compressor 211 may pressurize the air and supply air to the cathode 202 of the fuel cell stack 201. The intercooler 212 may cool the compressed air provided by the air compressor 211. The upstream shut-off valve 213 is in an open state during the operation of the fuel cell system 200 and is closed when the fuel cell system 200 is in a shutdown state. The exhaust throttle valve 214 may discharge the reacted cathode gas and may also adjust the gas pressure at the outlet of the cathode 202 and the flow rate of the gas supplied to the fuel cell stack 201. The bypass valve 215 may be opened when the upstream shut-off valve 213 is closed to discharge the air provided by the air compressor 211. The tailpipe muffler 216 may reduce the noise when the fuel cell system 200 exhausts.

[0031] The fuel cell system 200 may further include a sensor 220, which may include, for example, sensors 220-1 to 220-7. The sensor 220-1 may be disposed at the air inlet of the anode 203 and may detect temperature and pressure. The sensor 220-2 may be disposed at the air outlet of the anode 203 and may detect temperature and pressure. The sensor 220-3 may be disposed at the air inlet of the cathode 202 and may detect temperature and pressure. The sensor 220-4 may be disposed between the intercooler 212 and the upstream shut-off valve 213 and may detect temperature and pressure. The sensor 220-5 may be disposed at the air outlet of the cathode 202 and may detect temperature and pressure. The sensor 220-6 may be disposed in the tail exhaust of the fuel cell system 200 and may detect the concentration of hydrogen in the gas discharged from the fuel cell system 200. The sensor 220-7 may be disposed at the air inlet of the air compressor 211 and may detect the temperature, pressure and humidity of the air entering the fuel cell system 200. It should be understood that the embodiments of the present disclosure do not limit the number, position and type of sensors. For example, in some embodiments, the sensor 220-1 may include a temperature sensor and a pressure sensor, and the sensor 220-7 may include a temperature sensor, a pressure sensor and a humidity sensor.

[0032] The fuel cell system 200 further includes a fuel cell control unit (FCCU) 230. The FCCU 230 may control each component in the fuel cell system 200 to achieve overall control of the fuel cell system, including the management of hydrogen and air, the conversion and supervision of energy, the diagnosis and handling of faults, and communication with other systems. In some embodiments, the FCCU 230 may obtain the output voltage and output current of the fuel cell stack 201 from the DC / DC converter 204 and send them to the controller 110 in the vehicle 100. In some embodiments, the FCCU 230 may obtain the pressure value detected by the sensor 220-7 and send it to the controller 110 in the vehicle 100.

[0033] It should be understood that Figure 1 the illustrated vehicle 100 and Figure 2 the illustrated fuel cell system 200 are only examples of the embodiments of the present disclosure and should not be construed as limiting the solutions provided by the present disclosure. For example, in some embodiments, the vehicle 100 may further include other components that can obtain electrical energy from the fuel cell system 120 and the battery 130, such as a vehicle-mounted system, an air-conditioning system, vehicle lights, etc. The controller 110 may also distribute the electrical energy provided to these components between the fuel cell system 120 and the battery 130. Additionally, for example, in some embodiments, the fuel cell system 200 may include more or fewer components, such as a cooling subsystem.

[0034] Figure 3 FIG. 300 is a flowchart of a method for distributing output power according to some embodiments of the present disclosure. The method 300 may be executed by a device for distributing output power, which may be configured in a vehicle, or on the roadside or in the cloud, and may include, but is not limited to, a processor, a computer, a chip, a chip system, or a server, etc. The device may also be implemented in a software and / or hardware manner. In some embodiments, the device may be a controller configured in a vehicle, such as the controller 110 in Figure 1 . For ease of explanation, hereinafter, the controller will be used as the execution subject to schematically illustrate the method 300. As Figure 3 shown, the method 300 may include block 302 to block 306.

[0035] In block 302, the controller obtains a requested value of the output power of the vehicle, where the vehicle includes a fuel cell system and a storage battery. The requested value of the output power is the power value that the power source of the vehicle needs to output to meet the power consumption behaviors of the vehicle, such as acceleration, operation, and maintaining vehicle speed. In some embodiments, the vehicle is controlled by a driver, and the requested value of the output power may be determined based on the driver's input. Exemplarily, when the driver accelerates or maintains the vehicle speed, the driver steps on the accelerator pedal, and the controller may obtain the travel of the accelerator pedal and determine the output power demand value of the motor based on the predefined correspondence between the travel and the power. The controller may determine the requested value of the output power of the vehicle based on this. In some embodiments, the vehicle is controlled by an autonomous driving system, and the controller may obtain from the autonomous driving system the requested value of the output power determined by the autonomous driving system according to the autonomous driving strategy. In some embodiments, the requested value is determined by other devices, and the controller may also obtain the requested value of the output power from other devices.

[0036] In some embodiments, the requested value of the output power includes the output power demand value of the motor. In some embodiments, the requested value of the output power not only includes the output power demand value of the motor, but also includes the power demand values from other power-consuming components of the vehicle. Other power-consuming components include, but are not limited to, headlights, audio systems, in-vehicle infotainment systems, air conditioning systems, navigation systems, etc. That is, the requested value of the output power is the output power value used to meet the power demand of the entire vehicle. In some embodiments, the vehicle is controlled by a driver. Before the driver steps on the accelerator pedal, the power demand values of other components of the vehicle are satisfied by the storage battery of the vehicle. The controller may obtain the storage battery load to determine the power demand values of other power-consuming components of the vehicle. After the driver steps on the accelerator pedal, the controller may obtain the travel of the accelerator pedal to determine the driver's power request. The controller may use the sum of the driver's power request and the power demand values determined by the storage battery load as the requested value of the output power of the vehicle.

[0037] In block 304, the controller obtains the power distribution parameter of the vehicle, which includes at least one of the ambient pressure value of the environment where the vehicle is located and the heat dissipation value of the fuel cell system. In an embodiment of the present disclosure, the power distribution parameter represents a parameter related to the fuel cell system, and can indicate the environmental state that affects the performance and efficiency of the fuel cell system and / or the state of the fuel cell system itself. Exemplarily, the power distribution parameter may include, but is not limited to, the ambient pressure value of the environment where the vehicle is located, the heat dissipation value of the fuel cell system, etc.

[0038] In some embodiments, the power distribution parameter includes the ambient pressure value of the environment where the vehicle is located, and the controller can obtain the ambient pressure value from a sensor configured in the fuel cell system. Exemplarily, the controller can obtain Figure 2 the pressure value at the air inlet of the fuel cell system 200 from the sensor 220-7 in the fuel cell system 200 in

[0039] In block 306, the controller distributes the requested value of the output power between the fuel cell system and the battery based on the power distribution parameter. After obtaining the requested value of the output power, the controller can distribute the requested value of the output power to the fuel cell system and the battery such that the sum of the output power of the fuel cell system and the output power of the battery is equal to the requested value of the vehicle's output power. After obtaining the power distribution parameter, the controller can determine the proportion of the output power of the fuel cell system and the battery in the overall output power of the vehicle. In some embodiments, the method by which the controller distributes the requested value of the output power between the fuel cell system and the battery can be carried out with reference to the equivalent consumption minimization strategy, that is, the output power of the battery is equivalent to the hydrogen consumption of the fuel cell system, the equivalent consumption of the vehicle under various power distribution modes is calculated, and the power distribution mode that minimizes the equivalent consumption of the whole vehicle is selected. In the embodiments of the present disclosure, the controller determines the equivalent consumption of the vehicle based on the power distribution parameter.

[0040] It should be noted that although block 302 is shown before block 304 in Figure 3 , it is not intended to limit the order of the operations performed at block 302 and block 304. On the contrary, the operations performed at block 302 and block 304 can be carried out in a swapped order or simultaneously. That is, in some embodiments, the controller can obtain the power distribution parameter after receiving the requested value of the output power, and based on this, distribute the requested value of the output power between the fuel cell system and the battery. In some embodiments, the controller can first obtain the power distribution parameter, and then, when receiving the requested value of the output power, distribute the requested value. In some embodiments, the controller can obtain the requested value of the output power and the power distribution parameter simultaneously.

[0041] Through method 300, the controller can distribute the requested value of the vehicle's output power between the fuel cell system and the battery based on the power distribution parameter, that is, when distributing the output power, factors that can affect the fuel cell system are considered, such as environmental pressure and the heat dissipation of the fuel cell system. In this way, the best output power distribution mode that does not affect the fuel cell performance can be obtained, and the performance and efficiency of the whole vehicle can be optimized.

[0042] In some embodiments, in the foregoing block 306, the controller may determine a power limit range of the fuel cell system based on a requested value of the output power. The controller may determine an output power distribution method that minimizes the equivalent consumption of the vehicle within the power limit range. Exemplarily, for a fuel cell output power value within the power limit range, the controller may determine a corresponding battery output power value, and based on this, the controller may determine the corresponding equivalent consumption based on the power distribution parameter. The controller may traverse all fuel cell output power values within the power limit range and determine the corresponding battery output power values and equivalent consumption. The controller may select the fuel cell output power value and the battery output power value that minimize the equivalent consumption, and based on this, control the output power of the fuel cell system and the output power of the battery.

[0043] The power limit range may be expressed as [P lmin , P lmax , where P lmax represents the maximum limit value, and P lmin represents the minimum limit value. In some embodiments, the controller may determine the maximum limit value P lmax in the power limit range based on the requested value of the output power, the maximum charging power of the battery, and the maximum stack power of the fuel cell stack. Exemplarily, the maximum limit value P lmax may be determined by the following formula:

[0044] P lmax = min(P d + P batcmax , P smax ) (1)

[0045] Where P d represents the requested value of the output power of the vehicle, P batcmax represents the maximum charging power of the battery, and P smax represents the maximum stack power of the fuel cell stack. P batcmax and P smax may be predefined in the memory configured by the controller. It should be understood that the formulas provided in the embodiments of the present disclosure are only given schematically, and each formula may also undergo reasonable mathematical transformations. The present disclosure does not limit the specific presentation forms of the formulas.

[0046] In some embodiments, the controller may determine the minimum limit value P lmin in the power limit range based on the requested value of the output power, the maximum discharge power of the battery, and the minimum stack power of the fuel cell stack. Exemplarily, the minimum limit value P lmin may be determined by the following formula:

[0047] P lmin= min(max(P d + P batdcmax , P smin ), P smax ) (2)

[0048] where P d represents the requested value of the output power of the vehicle, P batdcmax represents the maximum discharge power of the battery, P smin represents the minimum stack power of the fuel cell stack, P smax represents the maximum stack power of the fuel cell stack. P batdcmax , P smin and P smax can be predefined in the memory configured in the controller.

[0049] In some embodiments, the method for the controller to allocate the requested value of the output power between the fuel cell system and the battery based on the power limit range can be as Figure 4 shown. Referring to Figure 4 , method 400 can include block 402 to block 414. In block 402, the controller takes the minimum limit value in the power limit range as the fuel cell output power value. In block 404, the controller determines the battery output power value based on the fuel cell output power value. Exemplarily, the battery output power value can be determined by the following formula:

[0050] P b = P d - P fcs (3)

[0051] where P b represents the battery output power value, P d represents the requested value of the output power of the vehicle, P fcs represents the fuel cell output power value.

[0052] In block 406, the controller determines the equivalent consumption value of the vehicle based on the fuel cell output power value and the battery output power value, on the basis of the power distribution parameter, where the power distribution parameter can be obtained in the aforementioned block 304. In block 408, the controller stores in the local memory the equivalent consumption value, the fuel cell output power value, and the battery output power value associated with each other. In block 410, the controller increases the incremental power value based on the fuel cell output power value, and takes the result as the new fuel cell output power value. The incremental power value can be predefined or determined based on the power limit range and the predefined calibration value. Exemplarily, the incremental power value can be determined by the following formula:

[0053] P ic = (P lmax - Plmin ) / CV (4)

[0054] P ic where represents the incremental power value, P lmax represents the maximum limit value, P lmin represents the minimum limit value, and CV represents a predefined calibration value.

[0055] In block 412, the controller determines whether the fuel cell output power value is within the power limit range. If so, it executes the aforementioned block 404. If not, it executes block 414. In block 414, the controller selects the smallest equivalent consumption value from the equivalent consumption values stored in the memory, and based on the fuel cell output power value and the battery output power value corresponding to the smallest equivalent consumption value, controls the output powers of the fuel cell system and the battery. In some embodiments, the controller may send the fuel cell output power value to the FCCU of the fuel cell system to control the output power of the fuel cell system, and the controller may send the battery output power value to the control unit of the battery to control the output power of the battery. Through method 400, the controller can iteratively determine the power distribution method between the fuel cell system and the battery within the power limit range, and determine the power distribution method that minimizes the equivalent consumption of the vehicle. By changing the value of CV, the number of iterative operations in the process of determining the distribution of the output power can also be adjusted, so that the computing power consumed by the controller in the process of distributing the output power can be flexibly adjusted.

[0056] In some embodiments, in the aforementioned block 306 or block 406, the controller may determine the target weight factor in the target power distribution model based on the power distribution parameters. Then, the controller may determine the equivalent consumption of the vehicle based on the target power distribution model including the target weight factor. Exemplarily, the target power distribution model may be the following formula:

[0057] P op = S × P fcs + z(t) × P b (5)

[0058] where P op represents the equivalent consumption value, S represents the target weight factor, P fcs represents the fuel cell output power value, z(t) represents the consumption factor, P bRepresents the output power value of the battery. Among them, z(t) can be determined by a proportional integral (PI) controller based on the state of charge (SOC) of the battery, and the controller can obtain z(t) from the PI controller. In some embodiments, the controller can also obtain the SOC of the battery and determine z(t) based on a predefined PI model.

[0059] In the target power distribution model, there is a target weight factor related to the fuel cell system, and the target weight factor is determined based on the power distribution parameters. Since the power distribution parameters can indicate the environmental state and / or the state of the fuel cell system itself that will affect the performance and efficiency of the fuel cell system, therefore, when the factors affecting the performance or efficiency of the fuel cell system change, the target weight factor will also change, thereby changing the proportion of the power output by the fuel cell system in the distribution of the output power. In this way, during the process of distributing the output power of the vehicle, the performance and efficiency of the fuel cell system and the battery can be comprehensively considered, and an optimal distribution result of the output power can be obtained, so that the performance and efficiency of the whole vehicle during driving can reach the optimal.

[0060] In some embodiments, in the foregoing block 304, the power distribution parameters obtained by the controller include the ambient pressure value of the environment where the vehicle is located. In some embodiments, the ambient pressure value is obtained by the controller from other devices, and in some embodiments, the ambient pressure value is obtained by the controller from a sensor for measuring the ambient pressure. In some embodiments, the FCCU can obtain the pressure value detected by a pressure sensor provided at the air inlet or the tail exhaust, and the controller can obtain this pressure value from the FCCU and use it as the ambient pressure value. In some embodiments, the controller can also directly obtain this pressure value from a sensor in the fuel cell system.

[0061] In some embodiments, in the foregoing block 306, the controller can determine the target weight factor in the target power distribution model based on the ambient pressure value. Exemplarily, a predefined pressure reference value can be set in the controller. The controller can determine the pressure difference between the pressure reference value and the obtained ambient pressure value, and the controller can determine the target weight factor based on this pressure difference and a predefined first correspondence set. The first correspondence set can include multiple correspondences between the pressure differences and the target weight factors. Exemplarily, the first correspondence set can exist in the form of a list, for example, it can be as shown in Table 1:

[0062] Table 1

[0063] Pressure difference (Pa) Target weight factor 1 0.1 1 2 0.2 0.9 3 0.3 0.8 4 0.4 0.7 5 0.5 0.6

[0064] The value of the target weight factor can decrease as the pressure difference increases. Thus, when the pressure difference becomes larger, that is, when the ambient pressure value becomes smaller, the value of the target weight factor becomes smaller. In the target power distribution model shown in, for example, the aforementioned formula (5), the output power P of the fuel cell system fcs the contribution to the equivalent consumption of the whole vehicle will become smaller. As a result, in the finally determined power distribution method that minimizes the equivalent consumption of the whole vehicle, the proportion of the output power of the fuel cell system can be higher. That is to say, when the external ambient pressure is relatively low, more output power can be allocated to the fuel cell system, thereby avoiding damage to the air compressor of the fuel cell system. In this way, it is possible to avoid the fuel cell system from operating at a low load when the ambient pressure is low, and the power distribution of the vehicle's output power can ensure the stable operation of the fuel cell system, enabling the optimal performance of the whole vehicle.

[0065] It should be understood that the correspondence between the pressure difference and the target weight factor shown in Table 1 is only an example given for the convenience of description in the embodiments of the present disclosure, and cannot be a limitation on the embodiments of the present disclosure. The correspondence between the pressure difference and the target weight factor can also be other predefined values, which can be pre-calibrated through experiments. In some embodiments, the first correspondence set can be pre-stored in the memory of the controller. In some embodiments, the first correspondence set can be obtained by the controller from other devices. For example, it can be obtained by the controller from a calibration server configured in the cloud. It should also be understood that the tables provided in the embodiments of the present disclosure are only examples and cannot be a limitation on the embodiments of the present disclosure. The correspondence sets (including the first correspondence set, the second correspondence set, and the third correspondence set) in the embodiments of the present disclosure can also exist in other forms other than tables.

[0066] In some embodiments, in the aforementioned block 304, the power distribution parameters obtained by the controller include the heat dissipation value of the fuel cell system. The controller can, for example, obtain the voltage and current currently output by the fuel cell stack, and based on this, determine the heat dissipation value of the fuel cell system. Exemplarily, the heat dissipation value can be determined by the following formula:

[0067] HD=(V ocs −V s )×I s (6)

[0068] where HD represents the heat dissipation value, V ocs represents the open-circuit voltage of the fuel cell stack, V s represents the current voltage of the fuel cell stack, and I s represents the current current of the fuel cell stack. Among them, V ocsIt is the potential difference between the two poles of the fuel cell stack when it is open - circuited. It can be determined through pre - experimental measurements and stored in the memory of the controller.

[0069] In some embodiments, in the aforementioned block 306, the controller may determine the target weight factor in the target power distribution model based on the heat dissipation value. Exemplarily, the controller may determine the target weight factor based on the heat dissipation value and a predefined second set of corresponding relationships. The second set of corresponding relationships may include the corresponding relationships between multiple heat dissipation values and the target weight factor. Exemplarily, the second set of corresponding relationships may exist in the form of a list, for example, as shown in Table 2:

[0070] Table 2

[0071] Heat dissipation value (W) Target weight factor 1 500 1 2 1000 0.8 3 1500 0.6 4 2000 0.4 5 2500 0.1

[0072] The value of the target weight factor may decrease as the heat dissipation value increases. Thus, when the heat dissipation of the fuel cell system becomes larger, the value of the target weight factor becomes smaller. In the target power distribution model shown in, for example, the aforementioned formula (5), the equivalent consumption will be less affected by the output power of the fuel cell system. Therefore, in the determined output power distribution method that minimizes the equivalent consumption of the vehicle, the proportion of the output power of the fuel cell system will be larger. That is to say, during the distribution of the output power, the greater the heat dissipation of the fuel cell system, the greater the output power allocated to the fuel cell system. For the fuel cell system, the proportion of heat dissipation during high - load operation is lower than that during low - load operation, and it has higher energy utilization and higher efficiency during high - load operation. Therefore, when the current heat dissipation value is relatively large, by increasing the output power of the fuel cell, the energy utilization of the fuel cell system can be improved, thereby improving the efficiency of the fuel cell system. In this way, the determined output power distribution method can ensure the high - efficiency operation of the fuel cell system and optimize the operation efficiency of the entire vehicle.

[0073] It should be understood that the corresponding relationship between the heat dissipation value and the target weight factor shown in Table 2 is only an example given for the convenience of explanation in the embodiments of the present disclosure and cannot be a limitation to the embodiments of the present disclosure. The corresponding relationship between the heat dissipation value and the target weight factor may also be other predefined values, which can be pre - calibrated through experiments. In some embodiments, the second set of corresponding relationships may be pre - stored in the memory of the controller. In some embodiments, the second set of corresponding relationships may be obtained by the controller from other devices. For example, the controller may obtain it from a calibration server configured in the cloud.

[0074] In some embodiments, in the foregoing block 304, the environmental parameters obtained by the controller include both the environmental pressure value and the heat dissipation value. In the foregoing block 306, the controller may determine the pressure difference between the pressure reference value and the obtained environmental pressure value, and determine the target weight factor based on the pressure difference, the heat dissipation value, and a predefined third correspondence set. The third correspondence set may include multiple correspondences between the pressure difference, the heat dissipation value, and the target weight factor. Exemplarily, the third correspondence set may exist in the form of a list. For example, it may be as shown in Table 3:

[0075] Table 3

[0076]

[0077] In Table 3, a pressure difference and a heat dissipation value jointly correspond to a target weight factor. For example, when the heat dissipation value is 500 W and the pressure difference is 0.2 Pa, the target weight factor is 0.9; when the heat dissipation value is 1500 W and the pressure difference is 0.3 Pa, the target weight factor is 0.4.

[0078] The value of the target weight factor is related to both the heat dissipation of the fuel cell system and the environmental pressure. Thus, in the process of allocating the output power, the efficiency and performance of the fuel cell system can be comprehensively considered, so that an output power allocation method that optimizes the performance and operating efficiency of the whole vehicle can be obtained. By allocating the output power of the vehicle in this way, the life of the fuel cell system and the battery can be extended while reducing the fuel consumption of the vehicle.

[0079] It should be understood that the correspondence between the heat dissipation value, the pressure difference, and the target weight factor shown in Table 3 is only an example given for the convenience of description in the embodiments of the present disclosure, and cannot be a limitation on the embodiments of the present disclosure. The correspondence between the heat dissipation value and the pressure difference and the target weight factor may also be other predefined values, which may be pre-calibrated through experiments. In some embodiments, the third correspondence set may be pre-stored in the memory of the controller. In some embodiments, the third correspondence set may be obtained by the controller from other devices. For example, it may be obtained by the controller from a calibration server configured in the cloud.

[0080] Figure 5 FIG. shows a schematic flowchart of a method 500 for allocating output power according to some embodiments of the present disclosure. The method 500 may be executed by a device for allocating output power. For example, it may be executed by a controller configured in a vehicle. The controller may be, for example, Figure 1 the controller 110 in. Next, taking the controller as the execution subject, the method 500 will be schematically described. Refer to Figure 5, method 500 may include block 502 to block 520.

[0081] In block 502, the controller obtains a requested value of the output power of the vehicle. In block 504, the controller obtains the ambient pressure value and the current current and current voltage of the fuel cell stack. In block 506, the controller determines a pressure difference based on the ambient pressure value and a predefined pressure reference value. In block 508, the controller determines a heat dissipation value of the fuel cell system based on the current current and current voltage of the fuel cell stack. In block 510, the controller determines a target weight factor in the target power distribution model based on the pressure difference and the heat dissipation value. In block 512, the controller obtains the maximum stack power of the fuel cell stack, the minimum stack power, the maximum charging power of the battery, and the minimum discharging power. In block 514, the controller determines a power limit range of the fuel cell system based on the maximum stack power of the fuel cell stack, the minimum stack power, the maximum charging power of the battery, and the maximum discharging power.

[0082] In block 516, within the power limit range, the controller determines the equivalent consumption of the vehicle based on the target weight factor. The method in block 516 may be executed with reference to blocks 402 to 412 in the foregoing method 400. In block 518, the controller determines a fuel cell output power value and a battery output power value corresponding to the minimum equivalent consumption value, and uses them as a first power value for controlling the fuel cell system and a second power value for controlling the battery. In block 520, the controller sends the first power value to the FCCU of the fuel cell system to control the fuel cell system to output the first power value. The controller sends the second power value to the electronic control unit of the battery to control the battery to output the second power value.

[0083] Through method 500, based on a comprehensive consideration of the performance and efficiency of the fuel cell system and the battery, the requested value of the output power of the vehicle can be allocated, so that the lifetimes of the fuel cell system and the battery and the equivalent fuel consumption of the entire vehicle can be taken into account, and the performance and efficiency of the entire vehicle can be optimized.
