[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] With global energy shortages and soaring oil prices, finding new energy sources as alternatives to fossil fuels is of paramount importance. Fuel cells, the fourth generation of power generation technology following hydropower, thermal power, and nuclear power, are currently the only power devices that simultaneously offer the advantages of being pollution-free, highly efficient, widely applicable, noiseless, and capable of continuous operation. They are considered the most promising high-efficiency clean power generation technology of the 21st century. Their most significant characteristic is that the reaction process does not involve combustion, and energy conversion is not limited by the Carnot cycle, resulting in a high energy conversion rate.

[0052] In related technologies, fuel cell engines generate electricity at a constant power output, and the start and stop of the fuel cell engine are determined by changes in the State of Charge (SOC) range. This is entirely dependent on the size of the SOC range, meaning that the fuel cell will frequently charge and discharge, affecting the lifespan of the fuel cell.

[0053] Example 1

[0054] The first aspect of this application provides a discharge control method for a fuel cell, referring to... Figure 1 The methods include:

[0055] S1, acquire the output power change information of the vehicle during its journey along the preset route. This output power change information includes location information and output power information.

[0056] During vehicle operation, the output power of the fuel cell is often determined by the output power of the vehicle. That is, the output power of the battery needs to meet the power required by the vehicle. Therefore, it is necessary to obtain the output power change information of the vehicle in real time while it is traveling on a preset route, so as to determine the power required by the vehicle during the driving process.

[0057] Output power refers to the total power consumed by the entire vehicle, including the power of all components powered by the fuel cell, such as the drive motor and other hardware.

[0058] S2, based on location information and output power change information, divides the preset route into multiple segments and determines the discharge power information of each segment.

[0059] To reduce the power change rate of the fuel cell, the vehicle's journey is divided into multiple segments. In this embodiment, the route is divided into multiple segments. When the vehicle is traveling on any segment, the fuel cell maintains a fixed output frequency. Each time the vehicle passes through a segment, the fuel cell changes its power, thereby reducing the power change rate of the fuel cell.

[0060] The frequency of the fuel cell on different road segments is determined by the output power of the vehicle on that road segment. Therefore, after dividing the preset route into multiple road segments, the discharge information of the fuel cell corresponding to each road segment is determined according to the output power information of each road segment, so that the fuel cell can meet the power demand of the vehicle on that road segment when discharging.

[0061] S3, based on multiple road segments and the corresponding discharge power information for each road segment, constructs a fuel cell discharge chart.

[0062] By mapping multiple road segments to the discharge information of fuel cells, a fuel cell discharge chart representing the discharge power of the fuel cell on each road segment is obtained. This chart is then uploaded to a neural network library. Based on the coordinate information of multiple road segments and their corresponding discharge power information, the discharge power of the vehicle at each location on the preset route is determined. In other words, by determining the road segment corresponding to the vehicle's coordinates in the chart, the power that the fuel cell should output can be determined.

[0063] S4, when it detects that the vehicle is traveling on the preset route again, controls the vehicle's fuel cell to discharge according to the corresponding discharge power based on the fuel cell discharge chart.

[0064] The system acquires the vehicle's location in real time during its journey and retrieves a fuel cell discharge chart from a neural network library. It then determines the road segment in the fuel cell discharge chart corresponding to the vehicle's coordinates, thereby determining the vehicle's discharge power at that location. The fuel cell power changes once each time the vehicle passes through a road segment, thus meeting the vehicle's power demand throughout the preset road segment while reducing the vehicle's power change rate.

[0065] When the vehicle travels on a preset route, the system first acquires the vehicle's initial location, then its current location in real time, and the output power as the vehicle passes through each location. This determines the output power variation information that characterizes the power demand as the location changes. Then, based on the location information, the preset route is divided into multiple segments. Simultaneously, based on the output power variation information, the discharge power corresponding to each segment is determined, resulting in the discharge power information for each segment. This generates a fuel cell discharge chart characterizing the fuel cell discharge power on each segment. When the vehicle travels on the preset route again, the system controls the fuel cell to discharge according to the fuel cell discharge chart and the discharge power corresponding to the vehicle's location. This reduces the fuel cell power variation rate and improves the fuel cell's lifespan.

[0066] In some embodiments, refer to Figure 2 The methods also include:

[0067] S101, when the vehicle is detected to be traveling on the preset route again, the discharge power change information corresponding to the preset route is reacquired.

[0068] Each time the vehicle travels on the preset route, the power required by the vehicle may vary due to environmental conditions or the vehicle's own condition, or it may not be the normal power output situation. For example, when the vehicle is in different weather conditions or has different loads, the output power required by the vehicle will be different. Therefore, whenever the vehicle travels on the preset route again, the information on the change in discharge power is re-acquired and used as a basis for correction to correct the previous data in order to improve the applicability and accuracy of the method.

[0069] S102, The fuel cell discharge chart is corrected based on the discharge power change information to obtain a new fuel cell discharge chart.

[0070] Once the vehicle's discharge power change information is obtained, the rest is input into the vehicle's database. By statistically integrating all the discharge power change information, the discharge power change information that best reflects the ideal situation is determined. This information is then used to determine the discharge power information and the fuel cell discharge chart. The discharge power information for each segment is then redefined according to the previous segmentation strategy, thereby constructing a new fuel cell discharge chart. This improves the applicability and accuracy of the fuel cell discharge chart, resulting in a better energy management solution.

[0071] In some embodiments, refer to Figure 3 The methods also include:

[0072] S201, Determine the power change rate of the fuel cell based on the fuel cell discharge chart.

[0073] Since the fuel cell's power changes every time it passes through a road segment, the number of road segments affects the fuel cell's power change rate. A higher number of segments results in a more tailored power supply to the vehicle, better meeting its electrical needs, but also increases the fuel cell's power change rate, thus having a greater impact on the fuel cell itself. Therefore, once the fuel cell discharge chart is determined, the fuel cell's power change rate is determined based on the chart.

[0074] S202, When the fuel cell discharges according to the fuel cell discharge chart, obtain the change in the fuel cell's lifespan.

[0075] Different fuel cells have different acceptable power change rates without affecting their lifespan. That is, the impact of the power change rate on the lifespan varies for different vehicles or fuel cells. Therefore, when a fuel cell discharges according to the fuel cell discharge chart, the degree of impact of this discharge process on the lifespan of the fuel cell should be determined based on the fuel cell's condition.

[0076] By conducting preliminary experiments to determine the impact of different power change rates on the fuel cell, the preset power change rate that affects the fuel cell's lifespan can be determined, thereby determining whether the power change rate of the fuel cell during discharge according to the fuel cell discharge chart exceeds the preset power change rate.

[0077] S203, when the power change rate is detected to be higher than the preset change rate, causing the lifespan change to exceed the preset standard, the number of segments in the preset route is reduced to obtain a new fuel cell discharge chart.

[0078] When the power change rate is detected to be higher than the preset change rate, resulting in a lifespan change exceeding the preset standard, it can be considered that the power change rate during the discharge of the fuel cell according to the fuel cell discharge chart has a significant impact on the lifespan of the fuel cell, i.e., the power change rate is high. The power change rate is then redefined, i.e., the number of segments in the preset route is reduced, thereby reducing the power change rate and effectively improving the protection effect on the fuel cell.

[0079] The method also includes:

[0080] When the detected power change rate is not higher than the preset change rate, the number of segments in the preset route is increased to obtain a new fuel cell discharge chart.

[0081] If the detected power change rate is not higher than the preset change rate, then the power change rate is within the range that the fuel cell can withstand. Therefore, in order to improve the power supply effect to the vehicle, the number of segments in the preset route is increased, thereby increasing the power change rate of the fuel cell, so that the discharge effect of the fuel cell is more in line with the power requirements of the vehicle.

[0082] In some embodiments, refer to Figure 4 Acquire information on the output power changes of the vehicle during its journey along a preset route, including:

[0083] S301, Obtain location information to determine the vehicle's position on the preset route.

[0084] During vehicle operation, the route is first determined based on the starting point and destination selected by the driver in the navigation system, or the selected route, and then set as the preset route.

[0085] In the case of the initial trip on the preset route, without a fuel cell discharge chart as the power supply strategy, the fuel cell will supply power according to the output power required by the vehicle during this trip.

[0086] First, based on the navigation system or the vehicle's driving conditions, such as speed and direction information, the location information is obtained, thereby determining the vehicle's corresponding position on the preset route.

[0087] S302, acquires the vehicle's output power at various locations to obtain output power information, including motor power and accessory power.

[0088] During operation, the power of the motor and the power of other electrical equipment are detected to determine the power of the vehicle at its current location. By combining this power with the location information, the output power, i.e. the required power, of the vehicle at each location along the entire preset route can be determined.

[0089] S303, based on the position information and the output power information, determines the output power change information that characterizes how the output power changes with the position information.

[0090] Based on the continuous output power obtained after the vehicle has continuously traveled through various locations, the continuous output power changes of the vehicle during the driving process can be determined, that is, the power demand changes when the vehicle travels on the preset route again. This can then be used as reference information for the output power of the fuel cell when the vehicle travels on the preset route again.

[0091] In some embodiments, refer to Figure 5 Based on location information and output power variation information, the preset route is divided into multiple segments, and the discharge power information of each segment is determined, including:

[0092] S401 divides the preset route into multiple road segments according to the preset processing method.

[0093] For example, based on the vehicle's driving process, according to the preset processing method, the preset route is divided into multiple segments of equal length according to a fixed segment length, thereby obtaining multiple segments of equal length. Alternatively, according to a fixed number of segments, such as 5 segments, the preset route will be divided into 5 segments regardless of the preset route length. If the preset route is X0-Xn, then the multiple segments are X0-X1, X1-X2, ..., Xn-1-Xn, thus segmenting the preset route when the vehicle first travels on it.

[0094] S402, the output power change information is segmented according to the segmentation of the preset route to obtain the output power change information corresponding to each segment.

[0095] The output power change information is the output power change information corresponding to the location information. Therefore, after the road segment is pre-segmented, the output power change information is segmented according to the segmentation of the road segment, so that each road segment is associated with a segment of output power change information.

[0096] S403 processes the output power change information corresponding to each road segment according to the preset processing method to determine the discharge power information of each road segment.

[0097] After obtaining the segmented road segments and the corresponding output power change information, the output power change information is processed according to a preset processing method. In some specific embodiments, the minimum intermediate difference method is used to calculate the required power generation. The drive motor power P1, accessory power P2, discharge power P3, and preset route X0-Xn are processed according to the following preset processing method:

[0098]

[0099] The P3-1, P3-2, ..., P3-n corresponding to multiple segments are obtained. When the number of groups is 5, the fuel cell discharge chart shown in Table 1 below can be obtained and uploaded to the neural network library.

[0100] Table 1

[0101]

[0102]

[0103] In some embodiments, refer to Figure 6 According to the fuel cell discharge chart, the vehicle's fuel cell is controlled to discharge at the corresponding discharge power, including:

[0104] S501, Obtain the vehicle's current location and determine the current road segment corresponding to the current location among multiple road segments.

[0105] When a vehicle is detected traveling on a preset route, after starting from the starting point of the preset route, the relative position of the vehicle on the preset route is determined based on GPS and time, current vehicle speed, drive power, SOC and other parameters, thereby determining which of the multiple road segments the current position corresponds to.

[0106] S502, Based on the current road segment, determine the segmented discharge power corresponding to the current road segment in the fuel cell discharge chart.

[0107] Once the road segment corresponding to the vehicle's location is determined, the discharge power corresponding to that road segment in the fuel cell discharge chart is obtained, which is the discharge power of the fuel cell when the vehicle is on that road segment.

[0108] S503 controls the fuel cell to discharge in stages according to the discharge power to power the vehicle.

[0109] After receiving the power generation capacity, the vehicle ECU requests the fuel cell to generate power according to that capacity, thereby achieving power generation control for the entire vehicle.

[0110] In other embodiments, this control method not only controls the power generation process of the fuel cell, but also controls the driving process of the drive system (such as the drive motor, motor controller, etc.), and obtains various relevant parameter values, including position information, accelerator pedal opening, brake pedal opening, drive torque, drive power, torque loading slope, etc. Based on the efficiency of the drive system as an indicator, for example, when the motor speed is 800 rpm, the accelerator pedal opening is 30%, and the reasonable range of drive torque value and torque slope is 400Nm-800Nm and 1000Nm / s-4000Nm / s, respectively. The drive motor efficiency corresponding to each scheme is different. The average efficiency of driving for 10 seconds with 400Nm and 1000Nm / s is 95%, the efficiency of driving for 10 seconds with 500Nm and 2000Nm / s is 93%, and the efficiency of driving for 10 seconds with 800Nm and 4000Nm / s is 95%. By selecting the most efficient drive strategy the more times the vehicle is driven, the purpose of improving the vehicle's economic performance can be achieved.
