[0051] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure.

[0052] It is understood that the terms "first", "second", etc. in this disclosure are used to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other and do not indicate a specific order or importance.

[0053] It is further understood that although operations are described in a particular order in the accompanying drawings in the embodiments of the present disclosure, this should not be construed as requiring that the operations be performed in the particular order shown or in a serial order, or that all of the operations shown be performed to obtain the desired results. In certain circumstances, multitasking and parallel processing may be advantageous.

[0054] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the corresponding data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.

[0055] FIG1 is a flow chart of a fuel cell power output control method according to an exemplary embodiment. As shown in FIG1 , the method is applied to a vehicle, which may be a fuel cell vehicle. The method includes the following steps:

[0056] In step S11, the voltage value of the vehicle voltage platform is obtained.

[0057] In step S12, the voltage value of the voltage platform is compared with the preset voltage range of the vehicle fuel cell, and the preset voltage range of the fuel cell includes a preset first voltage range and a second voltage range; wherein, the first voltage range is the voltage range in which the fuel cell can output at rated power, and the second voltage range is the voltage range in which the output power of the fuel cell system stack is limited.

[0058] Exemplarily, the vehicle voltage platform refers to the whole vehicle bus voltage platform of the fuel cell vehicle. A fuel cell vehicle (FCV) is a vehicle that obtains electrical energy for use by the whole vehicle after a chemical reaction with the on-board fuel. The on-board fuel is generally hydrogen, which can undergo an oxidation-reduction chemical reaction with oxygen in the atmosphere to generate electricity to drive the motor to work, and the motor drives the various mechanical structures in the vehicle to work, thereby driving the vehicle forward. At present, the whole vehicle architecture of fuel cell vehicles is equipped with fuel cells and power batteries. In one possible embodiment, the fuel cell can be used as the main power source and the power battery as the auxiliary power source.

[0059] During vehicle operation, the voltage value of the vehicle voltage platform is obtained and compared with the preset voltage range of the vehicle fuel cell. The vehicle fuel cell can be preset with two voltage ranges, namely the first voltage range and the second voltage range mentioned above.

[0060] When the voltage value is within the first voltage range, the fuel cell of the vehicle can output at rated power, and when the voltage value is within the second voltage range, the output power of the fuel cell system of the vehicle is limited; for example: the relationship between the engine voltage and the fuel cell power is shown in Table 1, the rated output power of the fuel cell system is 100KW, the vehicle voltage operating range is 350-650V, the fuel cell operating voltage range is between 300-850V, the above-mentioned first voltage range of the fuel cell is between 400-750V, and the above-mentioned second voltage range of the fuel cell is between 300-400V and between 750-850V. When the voltage value of the vehicle voltage platform is obtained to be any value between 400-750V, the fuel cell of the vehicle uses the rated power of 100KW as the output power. When the voltage value of the vehicle voltage platform is obtained to be any value between 300-400V and between 750-850V, the output power of the fuel cell is as shown in Table 1.

[0061] Table 1 Relationship between engine voltage and power

[0062] It can be understood that the voltage data and power data shown in Table 1 are exemplary. For different types of fuel cell vehicles, their voltage data and power data may be the same as or different from the data shown in Table 1.

[0063] In step S13, when the voltage value of the voltage platform is within the second voltage range, the first target power of the fuel cell of the vehicle is determined by obtaining the rechargeable power fed back by the power battery of the vehicle and the initial target power of the fuel cell of the vehicle.

[0064] For example, during operation of the vehicle, when the voltage value of the voltage platform of the vehicle is within the second voltage range, the initial target power of the vehicle's fuel cell is obtained. The initial target power of the vehicle's fuel cell can be compared with the rechargeable power fed back by the vehicle's power battery to obtain the minimum value between the initial target power of the fuel cell and the rechargeable power fed back by the vehicle's power battery, and the minimum value is used as the first target power of the vehicle's fuel cell. The initial target power of the fuel cell can be determined by the current nuclear charge number (also known as the state of charge, SOC) of the power battery, thereby determining the first target power of the vehicle's fuel cell system.

[0065] In step S14, the second target power of the vehicle's fuel cell and the output power of the fuel cell are determined by comparing the first target power of the vehicle's fuel cell with the maximum loadable power, where the maximum loadable power is the maximum loadable power of the fuel cell corresponding to the voltage value of the vehicle's voltage platform.

[0066] Exemplarily, the maximum loadable power of the fuel cell under actual operating conditions can be determined, and the first target power of the fuel cell can be compared with the maximum loadable power of the fuel cell at the voltage value of the voltage platform to obtain the minimum value, and the minimum value can be determined as the second target power of the vehicle fuel cell and the output power of the fuel cell. The maximum loadable power is the maximum loadable power of the fuel cell corresponding to the voltage value of the vehicle voltage platform of the vehicle.

[0067] Through the above technical solution, when obtaining the voltage value of the vehicle voltage platform, the voltage value range of the voltage platform is determined by comparing it with the preset voltage range of the vehicle fuel cell, and the fuel cell power strategy is determined based on the voltage value range. Taking into account the actual operating conditions, the minimum value of the comparison between the initial target power of the fuel cell, the rechargeable power of the power battery and the maximum loadable power of the fuel cell corresponding to the voltage value of the voltage platform is used to adjust the second target power and output power of the vehicle fuel cell, thereby improving the utilization rate of the fuel cell and increasing the vehicle's cruising range.

[0068] FIG2 is a flow chart of another fuel cell power output control method according to an exemplary embodiment. As shown in FIG2 , before step S11, the method further includes the following steps:

[0069] In step S15, the bus voltage value of the vehicle is obtained.

[0070] In step S16, the maximum loadable power is determined by the bus voltage value, which is used to represent the bus voltage value under actual operating conditions.

[0071] For example, the vehicle's fuel cell system can detect and obtain the vehicle's bus voltage value in real time, and calculate the maximum loadable power of the vehicle's fuel cell based on the obtained vehicle's bus voltage value, taking into account actual operating conditions. For example, when the vehicle's bus voltage value is obtained, the voltage value at the maximum output power of the vehicle's fuel cell is used as the output power at the vehicle's bus voltage value, and the output power under actual operating conditions is used as the maximum loadable power.

[0072] In step S17, the maximum loadable power is sent to the vehicle controller of the vehicle, so as to adjust the output power of the fuel cell so that the output power of the fuel cell is less than or equal to the maximum loadable power.

[0073] Exemplarily, the obtained maximum loadable power of the vehicle fuel cell is sent to the vehicle controller (VCU) of the vehicle via the vehicle's controller area network (CAN) bus for recording. When adjusting the output power of the vehicle's fuel cell, ensure that the output power of the vehicle's fuel cell is less than or equal to the maximum loadable power of the fuel cell.

[0074] For example: when the adjusted output power of the vehicle's fuel cell is 50KW and the maximum loadable power of the fuel cell calculated under the vehicle's bus voltage value is 50KW, then the output power of the vehicle's fuel cell can be 50KW, which is further compared with the first target power of the fuel cell to determine the second target power and output power of the vehicle's fuel cell.

[0075] FIG3 is a flow chart of another fuel cell power output control method according to an exemplary embodiment. As shown in FIG3 , step S13 includes the following steps:

[0076] In step S131 , the initial target power of the fuel cell of the vehicle and the chargeable power fed back by the power battery of the vehicle are obtained.

[0077] In step S132, the rechargeable power fed back by the power battery is compared with the initial target power of the fuel cell, and the minimum value between the initial target power of the fuel cell and the rechargeable power fed back by the power battery of the vehicle is determined as the first target power of the fuel cell of the vehicle.

[0078] For example, when the vehicle is running, the current SOC of the power battery is obtained through the vehicle controller of the vehicle, and the initial target power of the fuel cell of the vehicle is determined based on the correspondence between the SOC and the initial target power of the fuel cell. The initial target power of the fuel cell is compared with the rechargeable power of the power battery of the vehicle to take the minimum value, and the minimum value is used as the first target power of the fuel cell of the vehicle.

[0079] In one implementation, the initial target power corresponding to each SOC range can be pre-compared with the rechargeable power of the power battery according to the above strategy to take the minimum value of the two, thereby determining the first target power of the fuel cell corresponding to each SOC range, and generating an SOC adjustment vehicle energy strategy table. After determining the state of charge of the power battery, the corresponding first target power of the fuel cell system can be determined by querying the table.

[0080] For example, as shown in Table 2, when the voltage value of the vehicle voltage platform is obtained to be any value between 300-400V and 750-850V, the initial target power of the fuel cell is obtained by querying the power battery state of charge (SOC) table. In combination with the current actual working conditions of the vehicle, the initial target power of the fuel cell is compared with the rechargeable power of the power battery and the loadable power of the fuel cell to obtain the minimum value, and the first target power value of the fuel cell is determined.

[0081] Table 2 SOC regulation vehicle energy strategy

[0082] FIG4 is a flow chart of another fuel cell power output control method according to an exemplary embodiment. As shown in FIG4 , step S131 includes the following steps:

[0083] In step S1311, the current state of charge (SOC) of the power battery is obtained through the vehicle controller of the vehicle.

[0084] In step S1312, based on the correspondence between the SOC and the initial target power of the fuel cell, the initial target power of the fuel cell corresponding to the current SOC is determined as the initial target power of the fuel cell of the vehicle.

[0085] Exemplarily, the correspondence table between the initial target power and SOC of the vehicle's fuel cell is preset based on past experience. When the vehicle controller obtains the nuclear charge number of the power battery, it determines the initial target power corresponding to the current SOC based on the correspondence between the SOC and the initial target power of the fuel cell, and uses this as the initial target power of the vehicle's fuel cell.

[0086] FIG5 is a flow chart of another fuel cell power output control method according to an exemplary embodiment. As shown in FIG5 , step S14 includes:

[0087] In step S141, the maximum loadable power of the fuel cell at the voltage value of the voltage platform is determined. The maximum loadable power is used to represent the maximum loadable power of the fuel cell under actual operating conditions.

[0088] In step S142, the first target power of the fuel cell is compared with the maximum loadable power, and the minimum value between the first target power of the fuel cell and the maximum loadable power is determined as the second target power of the vehicle fuel cell to determine the output power of the fuel cell.

[0089] For example, when the maximum output power of the vehicle's fuel cell at the voltage value of the voltage platform is 50KW, the target power of the fuel cell 30KW is compared with the maximum loadable power 50KW of the vehicle's fuel cell at the voltage value of the voltage platform considering actual operating conditions, and the minimum value is taken as the second target power of the fuel cell, and the output power of the vehicle's fuel cell is determined to be 30KW.

[0090] FIG6 is a flow chart showing another fuel cell power output control method according to an exemplary embodiment. As shown in FIG6 , the method further includes the following steps:

[0091] In step S18, when the voltage value of the voltage platform is within the first voltage range, the minimum value is obtained by comparing the obtained initial target power of the vehicle fuel cell, the rechargeable power of the power battery and the maximum loadable power, and the third target power of the fuel cell issued by the vehicle controller is determined to determine the output power of the vehicle fuel cell.

[0092] Exemplarily, the vehicle can take the minimum value among the initial target power of the fuel cell, the rechargeable power of the power battery and the maximum loadable power of the fuel cell according to the vehicle energy management strategy and taking into account the actual operating conditions, and determine it as the third target power issued by the vehicle controller, and use the third target power issued by the vehicle controller as the output power of the vehicle fuel cell.

[0093] In step S19, when the voltage value of the voltage platform is not within the preset voltage value range of the vehicle fuel cell, the vehicle controller receives the fuel cell fault alarm information and the vehicle stops due to fault.

[0094] Exemplarily, when the voltage value of the voltage platform is not within the preset voltage range of the vehicle's fuel cell, the vehicle controller receives the fuel cell fault alarm information, and the vehicle shuts down due to a fault; for example, when the voltage value of the vehicle's voltage platform is lower than 300V or higher than 850V, it exceeds the operating voltage range of the fuel cell, the vehicle controller receives the fuel cell fault alarm information, and the vehicle shuts down due to a fault.

[0095] FIG7 is a flow chart showing another fuel cell power output control method according to an exemplary embodiment. As shown in FIG7 , step S18 may include the following steps:

[0096] In step S181, according to the vehicle energy management strategy, the minimum value among the initial target power of the fuel cell, the rechargeable power of the power battery and the maximum loadable power is determined as the third target power of the fuel cell issued by the vehicle controller.

[0097] In step S182 , the output power of the vehicle fuel cell is determined according to the third target power of the fuel cell.

[0098] For example, when the voltage value of the voltage platform of the vehicle is within the first voltage range, according to the vehicle energy management strategy of the vehicle and taking into account the actual operating conditions, the initial target power of the fuel cell, the rechargeable power of the power battery and the maximum loadable power are compared, and the minimum value is taken among the three, and the minimum value is used as the third target power of the fuel cell issued by the vehicle controller, and the third target power of the fuel cell issued by the vehicle controller is used as the output power of the vehicle fuel cell; for example: the loadable power of the vehicle fuel cell is 100KW, and the preset first voltage range of the fuel cell is 400-7 50V, when the voltage value is between 400-750V, compare the initial target power of the vehicle fuel cell, the rechargeable power of the power battery and the maximum loadable power of the vehicle fuel cell under actual operating conditions. When the initial target power of the vehicle fuel cell is 81KW and the rechargeable power of the power battery is 85KW, take the minimum value among 100KW, 85KW and 81KW as the third target power of the fuel cell issued by the vehicle controller. The third target power of the fuel cell issued by the vehicle controller is 81KW, thereby determining that the output power of the fuel cell is 81KW.

[0099] Through the above scheme, when the voltage value of the vehicle voltage platform is obtained, the voltage value range of the voltage platform is determined by comparing it with the preset voltage range of the vehicle fuel cell, and the fuel cell power strategy is determined according to the voltage value range. When the voltage value range meets the voltage value range that the system can output the rated power, the vehicle operates according to the original energy management strategy under normal operating conditions. When the voltage value range is not within the voltage value range that the system can output the rated power, the output power of the vehicle fuel cell is further adjusted according to the first target power of the fuel cell and the maximum loadable power of the fuel cell corresponding to the voltage value of the voltage platform in combination with the actual operating conditions. The utilization rate of the fuel cell can be improved during the operation of the vehicle, and the vehicle's cruising range is improved.
