Description

Technical Field

[0001] This invention relates to the field of fuel cell technology, and in particular to a method, apparatus, electronic device, and storage medium for determining power supply mode. Background Technology

[0002] Fuel cell vehicles are an important category in the field of new energy vehicles, and due to the advantages of fuel cells such as no pollution, no noise and high efficiency, they are highly valued by major vehicle manufacturers.

[0003] To meet the power requirements of vehicles, two fuel cells are usually installed in vehicles. However, because there is no clear method for starting and stopping the fuel cells and distributing power when the fuel cells fail, the actual use of the batteries is unreasonable.

[0004] To address the aforementioned issues, it is necessary to improve the method for determining the power supply mode of fuel cells in vehicles. Summary of the Invention

[0005] This invention provides a method, apparatus, electronic device, and storage medium for determining the power supply mode, in order to solve the problem of unreasonable battery activation when multiple fuel cells exist in a vehicle and the fuel cell supplying output power to the vehicle is determined based on the number of start-stop cycles.

[0006] In a first aspect, embodiments of the present invention provide a method for determining a power supply mode, including:

[0007] When the target vehicle is detected to be starting, the power to be consumed by the target vehicle is determined;

[0008] The power supply battery in the target vehicle is determined based on the battery operating state of at least one battery to be used in the target vehicle; wherein the at least one battery to be used includes a main battery and an auxiliary battery, and the battery operating state includes a normal state, a shutdown fault state, or a power-limited state.

[0009] Based on the power supply battery, the power to be consumed is provided to the target vehicle.

[0010] Secondly, embodiments of the present invention also provide a power supply mode determination device, comprising:

[0011] A power determination module is used to determine the power to be consumed by the target vehicle when the target vehicle is detected to be starting.

[0012] A battery determination module is used to determine the power supply battery in the target vehicle based on the battery operating state of at least one battery to be used in the target vehicle; wherein the at least one battery to be used includes a main battery and an auxiliary battery, and the battery operating state includes a normal state, a shutdown fault state, or a power-limited state;

[0013] A power supply module is used to provide the power to be consumed to the target vehicle based on the power supply battery.

[0014] Thirdly, embodiments of the present invention also provide an electronic device, comprising:

[0015] At least one processor; and

[0016] A memory communicatively connected to the at least one processor; wherein,

[0017] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the power supply mode determination method according to any embodiment of the present invention.

[0018] Fourthly, embodiments of the present invention also provide a computer-readable storage medium storing computer instructions, which are used to cause a processor to execute the power supply mode determination method described in any embodiment of the present invention.

[0019] The technical solution of this invention involves determining the power to be consumed by the target vehicle when it is detected that the vehicle is starting, obtaining the operating power of at least one controller to be used in the target vehicle, and obtaining the power to be consumed by the target vehicle based on the sum of the operating power of each controller. Further, based on the battery operating state of at least one battery to be used in the target vehicle, the power supply battery in the target vehicle is determined. The at least one battery to be used includes a main battery and an auxiliary battery. If both the main battery and the auxiliary battery are in normal condition or both are in a power-limited state, the battery with the shorter usage time is used as the power supply battery to reduce battery wear and extend battery life while meeting the power to be consumed. If the main battery is in normal condition and the auxiliary battery is in a shutdown fault state, the main battery is used as the power supply battery. If the main battery is in normal condition and the auxiliary battery is in a power-limited state, and the battery supply power of the main battery is greater than the power to be consumed, the main battery is used as the power supply battery. If the battery supply power of the main battery is less than the power to be consumed, when the main battery reaches its rated power, both the main battery and the auxiliary battery are used as the power supply battery. If the main battery reaches its rated power and the auxiliary battery reaches a preset limit power, the main battery's power supply is controlled to provide output power to the target vehicle according to the upper limit. Based on the power supply battery, the power to be consumed is provided to the target vehicle. This solves the problem of unreasonable battery activation when multiple fuel cells exist in a vehicle, where the fuel cell providing output power to the vehicle is determined based on the number of start-stop cycles. By jointly determining the power supply battery for the vehicle based on the battery's operating status, battery usage time, and the vehicle's power demand, the power supply battery in the vehicle is determined, thereby achieving the effects of reasonably starting the fuel cells in the vehicle, reducing battery loss, and extending battery range.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0027] Example 1

[0028] Figure 1 The flowchart of a power supply mode determination method provided in Embodiment 1 of the present invention is applicable to situations where multiple fuel cells exist in a vehicle. By considering the battery's operating state, battery usage time, and the vehicle's power requirements, the method aims to reasonably activate the fuel cells while reducing battery losses and extending battery range. This method can be executed by a power supply mode determination device, which can be implemented in hardware and / or software. The power supply mode determination device can be configured in a computing device capable of executing the power supply mode determination method.

[0029] like Figure 1 As shown, the method includes:

[0030] S110. When the target vehicle is detected to be starting, determine the power to be consumed by the target vehicle.

[0031] The target vehicle can be understood as a vehicle equipped with dual fuel cells. The target vehicle can be a car, bus, or truck, etc., and this technical solution does not limit the type of vehicle. The power to be consumed can be understood as the power required by the target vehicle during startup or use when operating the vehicle's controller.

[0032] In practical applications, determining the power to be consumed by the target vehicle includes: identifying at least one controller to be used in the target vehicle; and superimposing the controller power corresponding to at least one activated controller to obtain the power to be consumed corresponding to the target vehicle.

[0033] The controller to be used can be understood as the controller installed in the target vehicle. This can include hardware controllers, such as the body control unit controller, engine controller, steering power controller, steering wheel controller, and electronic parking brake system controller, as well as software controllers, such as entertainment and audio-visual controllers. In actual use, the controller to be used includes both activated and deactivated controllers. Activated controllers refer to those in operation within the target vehicle, while deactivated controllers refer to those in a deactivated state.

[0034] Generally, a target vehicle contains numerous controllers. During vehicle startup or use, these controllers need to be activated to assist vehicle operation or meet user needs. Understandably, each controller consumes power to ensure normal operation when the target vehicle is started. For example, if the body control unit controller, steering power controller, steering wheel controller, and electronic parking brake system controller are operating, the power consumed by each controller during normal operation is the corresponding power consumption of the target vehicle.

[0035] It should be noted that the controller in this technical solution is not limited to the vehicle controller itself, but may also include software controllers in the target vehicle, such as entertainment and audio-visual controllers. In other words, the term "controller" in this technical solution is a general term, referring to all hardware or software controllers in the target vehicle that require power from the target vehicle.

[0036] S120. Determine the power supply battery in the target vehicle based on the battery operating state of at least one battery to be used in the target vehicle.

[0037] In this context, the battery to be used can be understood as a fuel cell used to provide output power to the target vehicle. In this technical solution, the target vehicle includes at least one battery to be used; preferably, the number of batteries to be used is two. The power supply battery can be understood as the fuel cell that provides power to the target vehicle when the number of batteries to be used in the target vehicle is greater than one, for example, two batteries.

[0038] In this technical solution, two fuel cells are installed in the target vehicle to provide output power to the target vehicle. These two fuel cells can be fuel cells of the same type and function, or they can be fuel cells with differences. In practical applications, the vehicle manufacturer can set them within the allowable range.

[0039] In this technical solution, if the two fuel cells are identical, one fuel cell is referred to as the main cell and the other as the auxiliary cell for easy distinction.

[0040] In practical applications, taking a target vehicle containing both a main battery and an auxiliary battery as an example, the power supply battery providing output power to the target vehicle will also differ depending on the operating state of each fuel cell. In other words, in this technical solution, to meet the output power supply requirements of the target vehicle, it is necessary to first determine the operating state of each battery to be used, and then determine the power supply battery for the target vehicle based on the operating state of each battery.

[0041] In this technical solution, the battery operating state of the battery to be used includes normal state, shutdown fault state, or power limitation state.

[0042] In this context, "normal state" refers to the battery state in which the battery to be used can normally provide output power to the target vehicle. "Shutdown fault state" refers to the battery state in which the battery to be used is unable to provide output power to the target vehicle due to a battery malfunction. "Power limiting state" refers to the battery state in which the battery to be used is controlled to provide output power to the target vehicle at a preset limited power.

[0043] It should be noted that the advantage of setting a power limit for the battery in use is that when the target vehicle experiences situations such as increased battery temperature, increased air pressure, increased water pressure, or increased water temperature, the output power of the battery in use can be limited to reduce the wear and tear on the battery in use.

[0044] Optionally, based on the battery operating state of at least one battery to be used in the target vehicle, the power supply battery in the target vehicle is determined, including: if the battery operating states of both the main battery and the auxiliary battery are normal, then the first battery usage time of the main battery and the second battery usage time of the auxiliary battery are determined respectively; determining whether the first battery usage time is greater than the second battery usage time; if so, then the auxiliary battery is determined to be the power supply battery of the target vehicle; if not, then the main battery is determined to be the power supply battery of the target vehicle.

[0045] The first battery usage time refers to the total operating time of the main battery from startup to the current moment, during which it provides output power to the target vehicle. The second battery usage time refers to the total operating time of the auxiliary battery from startup to the current moment, during which it provides output power to the target vehicle.

[0046] Specifically, when the target vehicle is detected to be starting up, if the total power consumed by at least one controller in the target vehicle is relatively low, the target vehicle can be powered by either the main battery or the auxiliary battery using a fuel cell. The advantage of this setup is that when the output power of one battery is sufficient to meet the power requirements of all controllers in the target vehicle, prioritizing the use of one battery to provide output power reduces battery wear by decreasing the number of start-stop cycles.

[0047] Specifically, if both the main battery and the auxiliary battery are in normal condition when the target vehicle starts, the usage time of the main battery and the auxiliary battery is compared, and the battery with the shorter usage time is selected as the power supply battery for the target vehicle. The advantage of this setting is that it can meet the power requirements of the target vehicle while avoiding a large difference in the usage time of the two batteries, and maximizing the target vehicle's battery range.

[0048] Optionally, if both the main battery and the auxiliary battery are in a power-limited state, the power supply to the target vehicle is determined based on the battery usage time of the main battery and the auxiliary battery.

[0049] The reason is that if both the main battery and the auxiliary battery are in a power-limited state, both batteries need to provide output power to the target vehicle according to the preset power limit. In this case, similar to when both batteries are in a normal state, the battery usage time of the main battery and the auxiliary battery is compared, and the battery with the shorter usage time is used as the power supply battery for the target vehicle.

[0050] For example, if both the main battery and the auxiliary battery are in a power-limited state, and the usage time of the first battery is longer than that of the second battery, then the auxiliary battery is used as the power supply battery for the target vehicle; conversely, if the usage time of the first battery is shorter than that of the second battery, then the main battery is used as the power supply battery for the target vehicle.

[0051] S130, based on the power supply battery, provides the power to be consumed to the target vehicle.

[0052] The power to be consumed can be understood as the sum of the controller power corresponding to at least one controller to be used during the startup or operation of the target vehicle.

[0053] Specifically, battery priorities are determined based on the operating states of the main battery and auxiliary battery, and the highest-priority battery is designated as the power supply battery for the target vehicle. Based on this, the vehicle controller of the target vehicle can control the power supply battery to provide the power to be consumed by the target vehicle.

[0054] The technical solution of this invention involves determining the power to be consumed by the target vehicle when it is detected that the vehicle is starting, obtaining the operating power of at least one controller to be used in the target vehicle, and obtaining the power to be consumed by the target vehicle based on the sum of the operating power of each controller. Further, based on the battery operating state of at least one battery to be used in the target vehicle, the power supply battery in the target vehicle is determined. The at least one battery to be used includes a main battery and an auxiliary battery. If both the main battery and the auxiliary battery are in normal condition or both are in a power-limited state, the battery with the shorter usage time is used as the power supply battery to reduce battery wear and extend battery life while meeting the power to be consumed. If the main battery is in normal condition and the auxiliary battery is in a shutdown fault state, the main battery is used as the power supply battery. If the main battery is in normal condition and the auxiliary battery is in a power-limited state, and the battery supply power of the main battery is greater than the power to be consumed, the main battery is used as the power supply battery. If the battery supply power of the main battery is less than the power to be consumed, when the main battery reaches its rated power, both the main battery and the auxiliary battery are used as the power supply battery. If the main battery reaches its rated power and the auxiliary battery reaches a preset limit power, the main battery's power supply is controlled to provide output power to the target vehicle according to the upper limit. Based on the power supply battery, the power to be consumed is provided to the target vehicle. This solves the problem of unreasonable battery activation when multiple fuel cells exist in a vehicle, where the fuel cell providing output power to the vehicle is determined based on the number of start-stop cycles. By jointly determining the power supply battery for the vehicle based on the battery's operating status, battery usage time, and the vehicle's power demand, the power supply battery in the vehicle is determined, thereby achieving the effects of reasonably starting the fuel cells in the vehicle, reducing battery loss, and extending battery range.

[0055] Example 2

[0056] Based on the above embodiments, the determination of the power supply battery in the target vehicle is further refined according to the battery operating state of at least one battery to be used in the target vehicle.

[0057] See you again Figure 1 The method includes:

[0058] S210. When the target vehicle is detected to be starting, determine the power to be consumed by the target vehicle.

[0059] S220. Determine the power supply battery in the target vehicle based on the battery operating state of at least one battery to be used in the target vehicle.

[0060] In practical applications, if the main battery is in a normal state while the auxiliary battery is in a shutdown fault state, the main battery is determined as the power supply battery; if the main battery is in a normal state while the auxiliary battery is in a power-limited state, the power supply battery of the target vehicle is determined according to the power to be consumed by the target vehicle.

[0061] The reason is that when the main battery is in a normal state and the auxiliary battery is in a shutdown fault state, the auxiliary battery cannot work properly, so it can only rely on the main battery to provide output power to the target vehicle to meet the power consumption of the target vehicle.

[0062] If the main battery is in normal condition while the auxiliary battery is in a power-limited state, then the power supply battery in the target vehicle needs to be determined based on the power consumption of the target vehicle. Optionally, determining the power supply battery based on the power consumption of the target vehicle includes: determining whether the battery supply power of the main battery is greater than the power consumption; if so, then the main battery is determined as the power supply battery; if not, then when the battery supply power of the main battery reaches the rated power of the battery, the main battery and the auxiliary battery are determined as the power supply batteries of the target vehicle.

[0063] Specifically, when the main battery is in normal condition, it should be prioritized as the power supply battery for the target vehicle. However, before that, further judgment needs to be made based on the relationship between the main battery's power supply capacity and the power to be consumed. If the main battery's power supply capacity is greater than the power to be consumed, it indicates that the power supply from the main battery alone can meet the power requirements of the target vehicle. In this case, the main battery can be used as the power supply battery for the target vehicle.

[0064] If the main battery's power supply is less than the power to be consumed, it indicates that the target vehicle requires a relatively high output power, and the main battery alone cannot meet the vehicle's power demand. Therefore, based on the main battery as the power supply battery, if the main battery's power supply has reached its rated power, in order to reduce main battery losses and extend its range, when the power to be consumed exceeds the main battery's rated power, the auxiliary battery is activated to provide the excess power to the target vehicle. In other words, when the main battery's power supply reaches its rated power, both the main battery and the auxiliary battery operate as power supply batteries to meet the target vehicle's power requirements.

[0065] Optionally, the power to be compared is obtained based on the sum of the power supplied by the first battery of the main battery and the power supplied by the second battery of the auxiliary battery; it is determined whether the power to be compared is greater than the power to be consumed; if so, the main battery and the auxiliary battery are used as power supply batteries; if not, the power to be supplemented is obtained based on the difference between the power to be compared and the power to be consumed, so that the main battery and the auxiliary battery are used together as the power supply batteries, and the upper limit of the battery supply power adjustment value of the main battery is set as the battery supply power.

[0066] In this system, when both the main battery and the auxiliary battery jointly provide output power to the target vehicle, the output power of the main battery is used as the first battery supply power, and the output power of the auxiliary battery is used as the second battery supply power. The power to be supplemented refers to the difference between the power to be consumed and the power to be consumed when the power to be compared is less than the power to be consumed. For example, if the power to be consumed is 500W and the power to be compared is 400W, then the power to be supplemented is 100W. The upper limit battery supply power can be understood as the maximum output power that the battery to be used can provide to the target vehicle.

[0067] In actual use of the target vehicle, if the main battery is in normal condition and the auxiliary battery is in a power-limited state, even when the main battery provides output power to the target vehicle based on its rated power and the auxiliary battery based on its preset limited power, it still cannot meet the power requirements of the target vehicle. That is, when the main battery and auxiliary battery are working as power supply batteries, the power to be compared is less than the power to be consumed.

[0068] At this point, the power to be compared is obtained based on the sum of the power supplied by the first battery of the main battery and the power supplied by the second battery of the auxiliary battery. Further, the power to be supplemented is obtained based on the difference between the power to be consumed and the power to be compared. For example, if the power to be supplemented is 100W, the battery output mode of the main battery needs to be adjusted so that the main battery provides the power to be supplemented to the target vehicle according to the upper limit of the battery supply power, until the main battery reaches the upper limit of the battery supply power.

[0069] S230, based on the power supply battery, provides the power to be consumed to the target vehicle.

[0070] The technical solution of this invention involves determining the power to be consumed by the target vehicle when it is detected that the vehicle is starting, obtaining the operating power of at least one controller to be used in the target vehicle, and obtaining the power to be consumed by the target vehicle based on the sum of the operating power of each controller. Further, based on the battery operating state of at least one battery to be used in the target vehicle, the power supply battery in the target vehicle is determined. The at least one battery to be used includes a main battery and an auxiliary battery. If both the main battery and the auxiliary battery are in normal condition or both are in a power-limited state, the battery with the shorter usage time is used as the power supply battery to reduce battery wear and extend battery life while meeting the power to be consumed. If the main battery is in normal condition and the auxiliary battery is in a shutdown fault state, the main battery is used as the power supply battery. If the main battery is in normal condition and the auxiliary battery is in a power-limited state, and the battery supply power of the main battery is greater than the power to be consumed, the main battery is used as the power supply battery. If the battery supply power of the main battery is less than the power to be consumed, when the main battery reaches its rated power, both the main battery and the auxiliary battery are used as the power supply battery. If the main battery reaches its rated power and the auxiliary battery reaches a preset limit power, the main battery's power supply is controlled to provide output power to the target vehicle according to the upper limit. Based on the power supply battery, the power to be consumed is provided to the target vehicle. This solves the problem of unreasonable battery activation when multiple fuel cells exist in a vehicle, where the fuel cell providing output power to the vehicle is determined based on the number of start-stop cycles. By jointly determining the power supply battery for the vehicle based on the battery's operating status, battery usage time, and the vehicle's power demand, the power supply battery in the vehicle is determined, thereby achieving the effects of reasonably starting the fuel cells in the vehicle, reducing battery loss, and extending battery range.

[0073] The power determination module 210 is used to determine the power to be consumed by the target vehicle when the target vehicle is detected to be starting.

[0074] The battery determination module 220 is used to determine the power supply battery in the target vehicle based on the battery operating state of at least one battery to be used in the target vehicle; wherein the at least one battery to be used includes a main battery and an auxiliary battery, and the battery operating state includes a normal state, a shutdown fault state, or a power limiting state.

[0075] The power supply module 230 is used to provide power to be consumed to the target vehicle based on the power supply battery.

[0076] The technical solution of this invention involves determining the power to be consumed by the target vehicle when it is detected that the vehicle is starting, obtaining the operating power of at least one controller to be used in the target vehicle, and obtaining the power to be consumed by the target vehicle based on the sum of the operating power of each controller. Further, based on the battery operating state of at least one battery to be used in the target vehicle, the power supply battery in the target vehicle is determined. The at least one battery to be used includes a main battery and an auxiliary battery. If both the main battery and the auxiliary battery are in normal condition or both are in a power-limited state, the battery with the shorter usage time is used as the power supply battery to reduce battery wear and extend battery life while meeting the power to be consumed. If the main battery is in normal condition and the auxiliary battery is in a shutdown fault state, the main battery is used as the power supply battery. If the main battery is in normal condition and the auxiliary battery is in a power-limited state, and the battery supply power of the main battery is greater than the power to be consumed, the main battery is used as the power supply battery. If the battery supply power of the main battery is less than the power to be consumed, when the main battery reaches its rated power, both the main battery and the auxiliary battery are used as the power supply battery. If the main battery reaches its rated power and the auxiliary battery reaches a preset limit power, the main battery's power supply is controlled to provide output power to the target vehicle according to the upper limit. Based on the power supply battery, the power to be consumed is provided to the target vehicle. This solves the problem of unreasonable battery activation when multiple fuel cells exist in a vehicle, where the fuel cell providing output power to the vehicle is determined based on the number of start-stop cycles. By jointly determining the power supply battery for the vehicle based on the battery's operating status, battery usage time, and the vehicle's power demand, the power supply battery in the vehicle is determined, thereby achieving the effects of reasonably starting the fuel cells in the vehicle, reducing battery loss, and extending battery range.

[0080] The duration comparison submodule is used to determine whether the usage time of the first battery is greater than that of the second battery;

[0081] The first battery determination submodule is used to determine, if so, the auxiliary battery as the power supply battery for the target vehicle.

[0082] The second battery determination submodule is used to determine, if not, that the main battery is the power supply battery for the target vehicle.
