[0046] In order to enable ordinary persons in the art to better understand the technical solutions disclosed in the present invention, the technical solutions in the embodiments disclosed in the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary persons in the art without making creative work are within the scope of protection of the present invention.
[0047] It should be noted that the terms "first", "second", etc. in the specification and claims disclosed in the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments disclosed in the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.
[0048] Hydrogen fuel cell vehicles have the advantages of zero emissions, no pollution, high efficiency, long driving range, and low temperature resistance. Hydrogen energy is considered to be one of the most promising automotive power sources. Since the fuel cell system itself has shortcomings such as dynamic response hysteresis and inability to recover energy, in the automotive power system with fuel cells as the main power source, auxiliary power source lithium batteries are often equipped, forming the current common "hydrogen-lithium" hybrid power system. For the current common "hydrogen-lithium" hybrid fuel cell vehicles, taking into account the reliability of the current fuel cell use process, pure electric driving range requirements and other factors, they are often equipped with large-capacity lithium batteries to form an extended-range hydrogen fuel hybrid architecture.
[0049] The energy management of fuel cells and lithium batteries in a fuel cell system is particularly important, which will affect the power, economy and other performances of the vehicle. The energy management methods in the prior art usually result in higher hydrogen consumption and poor economy of the vehicle. At the same time, the vibration and noise of the accessories in the fuel cell are large, and the NVH performance of the vehicle is poor. Based on this, the present application provides an energy distribution method for a fuel cell system, which can improve the stability and smoothness of vehicle driving, improve driving comfort, and at the same time improve the reliability and durability of the fuel cell system, and has good economy.
[0050] See also Figure 1 , Figure 1It is a flowchart of a battery system operation control method shown according to an exemplary embodiment. This specification provides method operation steps as described in the embodiment or flowchart, but may include more or fewer operation steps based on conventional or non-creative labor. The order of steps listed in the embodiment is only one way of executing the steps among many orders, and does not represent the only execution order. When the actual system or server product is executed, it can be executed in sequence or in parallel according to the method shown in the embodiment or the accompanying drawings (for example, in a parallel processor or multi-threaded processing environment). Specifically, as Figure 1 As shown, the above method may include:
[0051] S101: Acquire initial capacity information, target capacity information of the lithium battery and first required power information of the vehicle.
[0052] In a specific embodiment, the vehicle may include a battery system, which may include a lithium battery and a fuel cell. Specifically, the fuel cell may be a hydrogen fuel cell. The initial capacity information of the lithium battery may be the remaining capacity information (State of Charge, SOC) of the lithium battery at the current moment, and the target capacity information may be the capacity information of the lithium battery expected at the current moment. The first power demand information of the vehicle fluctuates less over time, so as to avoid the rapid decay of the fuel cell life due to frequent jumps of the battery system with the real-time power demand, resulting in low energy supply efficiency of the battery system. When the output power information of the battery system is equal to the first power demand information of the vehicle, the capacity of the lithium battery can meet the target capacity. Specifically, the first power demand information may be the average power demand information of the vehicle within a period of time (preset duration), that is, the average value of the real-time power demand information corresponding to multiple moments within a period of time. The preset duration may be set according to actual application requirements.
[0053] In an optional embodiment, the above method may further include:
[0054] Obtain road condition information;
[0055] Determine the target capacity information based on the road condition information.
[0056] In a specific embodiment, the road condition information may include urban road conditions, suburban road conditions, and highway road conditions. The road condition information may be identified based on the vehicle-mounted Internet technology. Specifically, the vehicle driving road may be intelligently identified through vehicle sensing equipment and high-precision maps to determine whether it belongs to one of the urban road conditions, suburban road conditions, and highway road conditions. The road condition information may also be determined based on the average vehicle speed information of the vehicle within a preset historical duration. Specifically, a type of road condition information corresponding to any average vehicle speed information may be determined based on a preset correspondence between the average vehicle speed information and the road condition information. For example, when the average vehicle speed information is less than 50 km / h, the road condition information may be an urban road condition. When the average vehicle speed information is greater than or equal to 50 km / h and less than or equal to 100 km / h, the road condition information may be a suburban road condition. When the average vehicle speed information is greater than or equal to 100 km / h, the road condition information may be a highway road condition. The above-mentioned preset historical duration may be set according to actual application requirements.
[0057] In a specific embodiment, the target capacity information corresponding to the road condition information can be determined according to the preset correspondence between the road condition information and the target capacity information. For example, when the road condition information is an urban road condition, the target capacity information can be 30% to 40%; when the road condition information is a suburban road condition, the target capacity information can be 40% to 60%; when the road condition information is a highway road condition, the target capacity information can be 60% to 80%. The first required power information of the vehicle can be different according to the different road condition information. For example, when the road condition information is an urban road condition, the first required power information is low, when the road condition information is a highway road condition, the first required power information is high, and when the road condition information is a suburban road condition, the first required power information is relatively medium.
[0058] S103: When the initial capacity information is smaller than the target capacity information, determine compensation power information based on difference information between the initial capacity information and the target capacity information.
[0059] In a specific embodiment, under each road condition information, when the initial capacity information is less than the target capacity information, the compensation power information corresponding to the road condition information is determined based on the difference information between the initial capacity information and the target capacity information corresponding to the road condition information.
[0060] In an alternative embodiment, Figure 2 is a schematic diagram of a process for determining compensation power information according to an exemplary embodiment. Figure 2As shown, the above-mentioned determination of the compensation power information based on the difference information between the initial capacity information and the target capacity information may include:
[0061] S201: Obtain a power compensation coefficient corresponding to initial capacity information.
[0062] S203: Multiply the difference information between the initial capacity information and the target capacity information by the power compensation coefficient to obtain compensated power information.
[0063] Specifically, the difference between the target capacity information and the initial capacity information may be multiplied by the power compensation coefficient to obtain the compensated power information. The power compensation coefficient may be calibrated based on multiple tests.
[0064] S105: Determine target power information of the battery system based on the first required power information and the compensation power information.
[0065] In a specific embodiment, when the initial capacity information is less than the target capacity information, the vehicle is in a hybrid driving mode, that is, the fuel cell and the lithium battery jointly provide power to the vehicle. In addition to providing power for the vehicle, the fuel cell can also charge the lithium battery to restore the capacity of the lithium battery to meet the target capacity information. In this case, in order to quickly restore the capacity of the lithium battery to the target capacity, compensation can be performed on the basis of the vehicle's required power, and the compensated power is determined as the overall output power of the battery system. Specifically, the first required power information and the compensated power information can be summed to obtain the target power information of the battery system. By compensating for the vehicle's required power, the capacity of the lithium battery can be promoted to increase and quickly restored to the target capacity while ensuring the energy supply of the vehicle. The target power information of the above-mentioned battery system may include the first target power information of the lithium battery and the second target power information of the fuel cell.
[0066] In an optional embodiment, after determining the target power information of the battery system based on the first required power information and the compensation power information, the method may further include:
[0067] Based on the target power information, power allocation processing is performed on the lithium battery and the fuel cell to obtain first target power information of the lithium battery and second target power information of the fuel cell;
[0068] The operation of the lithium battery is controlled based on the first target power information, and the operation of the fuel cell is controlled based on the second target power information.
[0069] In a specific embodiment, based on the target power information of the fuel system, the first target power information of the lithium battery and the second target power information of the fuel cell are allocated, and the operation of the corresponding battery is controlled based on the corresponding power information. The sum of the first target power information of the lithium battery and the second target power information of the fuel cell is the target power information of the fuel system.
[0070] In an alternative embodiment, Figure 3 FIG. 1 is a flow chart showing a power allocation process according to an exemplary embodiment. Figure 3 As shown, the power allocation process for the lithium battery and the fuel cell is performed based on the target power information to obtain the first target power information of the lithium battery and the second target power information of the fuel cell, which may include:
[0071] S301: Acquire rated power information of the fuel cell.
[0072] S303: Determine the power distribution coefficient of the fuel cell based on the rated power information.
[0073] In a specific embodiment, the power allocation coefficient corresponding to any rated power information may be determined according to a preset correspondence between the rated power information and the power allocation coefficient of the fuel cell.
[0074] S305: Determine second target power information based on the target power information and the power allocation coefficient.
[0075] In a specific embodiment, determining the second target power information based on the target power information and the power allocation coefficient may include: multiplying the target power information and the power allocation coefficient to obtain the second target power information of the fuel cell.
[0076] S307: Determine the first target power information based on the difference information between the target power information and the second target power information.
[0077] In a specific embodiment, the target power information is subtracted from the second target power information of the fuel cell to obtain the first target power information of the lithium battery.
[0078] In an optional embodiment, the above method may further include:
[0079] When the initial capacity information satisfies the target capacity information, the first required power information is determined as the target power information.
[0080] In actual applications, when the initial capacity information meets the target capacity information, there is no need to compensate for the required power information. The vehicle is in hybrid driving mode, and then power distribution processing is performed on the fuel cell and the lithium battery according to the above target power information. For details, please refer to the above-mentioned detailed steps of performing power distribution processing on the lithium battery and the fuel cell based on the target power information to obtain the first target power information of the lithium battery and the second target power information of the fuel cell, which will not be repeated here.
[0081] Specifically, when the road condition information is an urban road condition, the initial capacity information meets the target capacity information, ensuring that when the vehicle arrives at the destination, the external power grid is used to charge the lithium battery as much as possible. Since the power demand of the vehicle is relatively low under urban conditions, the fuel cell system is operated at low power at this time. The fuel cell system is in a high-efficiency power generation area and has good economy; and since the vehicle speed is relatively low under urban road conditions, the output power of the fuel cell system is relatively low, the vibration and noise are small, and the NVH performance of the vehicle is good; when the road condition information is a suburban road condition, the initial capacity information meets the target capacity information, ensuring that the vehicle has a certain pure electric endurance when the fuel cell fails, reducing dependence on power grid charging. In addition, the power demand of the whole vehicle under suburban conditions is medium. At this time, the fuel cell system is operated at medium power. The fuel cell system is in a relatively high-efficiency power generation area and has good economy. Because the power of the fuel cell system is not too high, the vibration and noise are relatively small, and the NVH performance of the whole vehicle is also good. When the road condition information is a highway condition, the initial capacity information meets the target capacity information, ensuring that the whole vehicle has a longer pure electric range when the fuel cell fails, reducing dependence on grid charging, and the power demand of the whole vehicle under high-speed conditions is relatively high. At this time, the fuel cell system is operated at a higher power. Although the vibration and noise of the fuel cell system are large, the road noise and aerodynamic noise of the whole vehicle are also relatively large when driving at high speeds. The driving noise of the whole vehicle can easily cover the noise of the fuel cell system and will not significantly affect the NVH performance experience of the whole vehicle.
[0082] In the above embodiments, the overall output power of the corresponding fuel cell system can be determined according to the driving scenario, and the energy of the fuel cell and the lithium battery can be allocated based on this, so that the electric energy and hydrogen energy can be flexibly used. In each driving scenario, the output power of the fuel cell system is determined according to the difference between the actual capacity and the target capacity of the lithium battery, and the stable power demand of the vehicle over a period of time, so as to avoid frequent load changes of the fuel cell, thereby achieving high working efficiency of the fuel cell and low hydrogen consumption of the whole vehicle, effectively reducing the use cost of the user end, and having excellent economic performance.
[0083] In an optional embodiment, the above method may further include:
[0084] When the initial capacity information is greater than the target capacity information, obtaining second required power information of the vehicle;
[0085] The second required power information is determined as the first target power information of the lithium battery.
[0086] In a specific embodiment, when the initial capacity information is greater than the target capacity information, the vehicle is in a pure electric driving mode, and the vehicle is powered only by the lithium battery. The second required power information of the vehicle is used as the first target power information of the lithium battery, and the operation of the lithium battery is controlled by the first target power information. The second required power information of the vehicle can be the real-time required power information of the vehicle at the current moment, or it can be the average required power information over a period of time.
[0087] S107: Controlling the operation of the battery system based on the target power information so that the capacity information of the lithium battery meets the target capacity information.
[0088] In a specific implementation, the specific implementation process of the technical solution in the embodiment of the present application is as follows:
[0089] First, the vehicle's driving road is identified, and the vehicle's road condition information is determined to be one of an urban road condition, a suburban road condition, and a highway condition. When the vehicle's lithium battery capacity is greater than the target capacity corresponding to the road condition information, the vehicle is in a pure electric driving mode, and only the lithium battery provides power for the vehicle. The vehicle's current required power is obtained, and the vehicle's required power is determined as the power of the lithium battery, and the lithium battery operation is controlled by the power.
[0090] When the lithium battery capacity of the vehicle is less than the target capacity corresponding to the road condition information, the vehicle is in a hybrid driving mode, and the lithium battery and the fuel cell jointly provide power for the vehicle. Based on the average power demand within a certain historical period at the current moment, the average power demand is compensated, and the difference between the target capacity and the current battery capacity is multiplied by the compensation coefficient to obtain the compensation power, and the sum of the average power demand and the compensation power is determined as the total power corresponding to the lithium battery and the fuel cell. Then, the power of the lithium battery and the fuel cell is allocated based on the total power, and the power allocation coefficient corresponding to any rated power is determined according to the preset corresponding relationship between the rated power of the fuel cell and the power allocation coefficient of the fuel cell, and the total power and the allocation coefficient are multiplied to obtain the power of the fuel cell, and the total power is subtracted from the power of the fuel cell to obtain the power of the lithium battery, and then the operation of the fuel cell and the lithium battery are controlled accordingly with the above power.
[0091] When the lithium battery capacity of the vehicle meets the target capacity corresponding to the road condition information, the vehicle is in hybrid driving mode, and the lithium battery and fuel cell jointly provide power for the vehicle, and the average required power of the vehicle within a certain historical period at the current moment is determined as the total power corresponding to the lithium battery and the fuel cell, and then the power of the fuel cell and the lithium battery is allocated in the same manner as the case where the lithium battery capacity of the above-mentioned vehicle is less than the target capacity corresponding to the road condition information, and the operation of the fuel cell and the lithium battery are controlled accordingly.
[0092] It can be seen from the technical solutions provided in the above embodiments of this specification that the initial capacity information, target capacity information and the first required power information of the vehicle of the lithium battery are first obtained in this specification; the vehicle includes a battery system; when the initial capacity information is less than the target capacity information, the compensation power information is determined based on the difference information between the initial capacity information and the target capacity information; based on the first required power information and the compensation power information, the target power information of the battery system is determined; based on the target power information, the battery system is controlled to operate so that the capacity information of the lithium battery meets the target capacity information, thus, when the capacity of the lithium battery is less than the target capacity, compensation can be made on the basis of the vehicle required power according to the capacity difference, and the overall output power of the battery system is determined based on the compensated required power, so that the battery system operates at an appropriate power, reduces operating vibration and noise, improves the NVH performance of the vehicle, improves the stability, smoothness and driving comfort of the vehicle, and at the same time improves the reliability and durability of the fuel cell system. In addition, the overall output power of the corresponding fuel cell system can be determined according to the driving scenario, and the energy of the fuel cell and the lithium battery can be allocated based on this, so that electrical energy and hydrogen energy can be flexibly used. In each driving scenario, the output power of the fuel cell system is determined based on the difference between the actual capacity and the target capacity of the lithium battery, as well as the vehicle's stable power demand over a period of time, to avoid frequent load changes in the fuel cell. This ensures that the fuel cell has high energy supply efficiency and low hydrogen consumption for the entire vehicle, effectively reducing the user's usage cost and achieving excellent economic performance.
