It should be noted that the steps shown in the flow charts of the drawings can be implemented in a computer system such as a set of computer-executable instructions and, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.
图1是根据本发明实施例的车辆的燃料电池模块的控制方法的流程图，如图1所示，该车辆的燃料电池模块的控制方法包括如下步骤：Fig. 1 is a flowchart of a method for controlling a fuel cell module of a vehicle according to an embodiment of the present invention. As shown in Fig. 1 , the method for controlling a fuel cell module for a vehicle includes the following steps:
步骤S102，获取车辆启动时的需求功率；Step S102, obtaining the required power when the vehicle starts;
上述车辆采用燃料电池模块包括多个燃料电池***，以双燃料电池***为例，双燃料电池***包括第一燃料电池***与第二燃料电池***，且第一燃料电池***与第二燃料电池***在型号、配置参数等方面是相同的。The fuel cell module used in the vehicle above includes multiple fuel cell systems. Taking the dual fuel cell system as an example, the dual fuel cell system includes a first fuel cell system and a second fuel cell system, and the first fuel cell system and the second fuel cell system They are the same in terms of models, configuration parameters, etc.
步骤S104，判断需求功率是否大于第一功率阈值，其中，第一功率阈值为燃料电池***的高效率功率区间内的最大功率；Step S104, judging whether the required power is greater than a first power threshold, where the first power threshold is the maximum power within the high-efficiency power range of the fuel cell system;
需要说明的是，由于采用燃料电池模块，可以将其燃料电池***对应的高效率功率区间内的最大功率作为第一功率阈值。It should be noted that since the fuel cell module is used, the maximum power within the high-efficiency power range corresponding to the fuel cell system can be used as the first power threshold.
步骤S106，在需求功率大于第一功率阈值的情况下，则控制同时启动多个燃料电池***，其中，多个燃料电池***的输出功率之和为需求功率；Step S106, when the required power is greater than the first power threshold, then control to start multiple fuel cell systems at the same time, wherein the sum of the output powers of the multiple fuel cell systems is the required power;
在一种可选的实施方式中，多个燃料电池***至少包括第一燃料电池***和第二燃料电池***，在需求功率大于第一功率阈值的情况下，则控制同时启动多个燃料电池***，包括：判断需求功率是否大于第二功率阈值，其中，第二功率阈值大于第一功率阈值；依据判断结果，确定第一燃料电池***与第二燃料电池***的输出功率。In an optional implementation, the multiple fuel cell systems include at least a first fuel cell system and a second fuel cell system, and when the required power is greater than the first power threshold, the control starts multiple fuel cell systems simultaneously , comprising: judging whether the required power is greater than a second power threshold, wherein the second power threshold is greater than the first power threshold; and determining output powers of the first fuel cell system and the second fuel cell system according to the judging result.
在需求功率大于第一功率阈值时，此时可以进一步判断需求功率是否大于第二功率阈值，该第二功率阈值大于第一功率阈值，进而再依据判断结果，来确定第一燃料电池***与第二燃料电池***的输出功率。例如，在需求功率大于第二功率阈值的情 况下，则控制第一燃料电池***的输出功率、第二燃料电池***的输出功率分别为需求功率的二分之一；又例如，在需求功率大于第一功率阈值且小于或者等于第二功率阈值的情况下，则控制第一燃料电池***的输出功率为燃料电池***的功率区间内的最大功率、第二燃料电池***的输出功率为需求功率减去最大功率。When the required power is greater than the first power threshold, it can be further judged whether the required power is greater than the second power threshold. 2. Output power of the fuel cell system. For example, when the required power is greater than the second power threshold, the output power of the first fuel cell system and the output power of the second fuel cell system are controlled to be half of the required power respectively; When the first power threshold is less than or equal to the second power threshold, the output power of the first fuel cell system is controlled to be the maximum power within the power range of the fuel cell system, and the output power of the second fuel cell system is the required power minus Go for maximum power.
通过上述实施方式能够准确得到第一燃料电池***的输出功率、第二燃料电池***的输出功率。Through the above embodiments, the output power of the first fuel cell system and the output power of the second fuel cell system can be accurately obtained.
在具体实施过程中，上述第二功率阈值可以为燃料电池***的功率区间内的最大功率乘以预定倍数，预定倍数至少为2倍。In a specific implementation process, the above-mentioned second power threshold may be the maximum power within the power range of the fuel cell system multiplied by a predetermined multiple, and the predetermined multiple is at least 2 times.
另外，在控制第一燃料电池***的输出功率、第二燃料电池***的输出功率分别为需求功率的二分之一的同时，还可以采集第一燃料电池***与第二燃料电池***在相同输出功率下的电流，其中，第一燃料电池***对应的电流为第一电流，第二燃料电池***对应的电流为第二电流。In addition, while controlling the output power of the first fuel cell system and the output power of the second fuel cell system to be one-half of the required power, it is also possible to collect the same output power of the first fuel cell system and the second fuel cell system Current under power, wherein the current corresponding to the first fuel cell system is the first current, and the current corresponding to the second fuel cell system is the second current.
可选地，在采集第一燃料电池***与第二燃料电池***在相同输出功率下的电流之后，上述方法还包括：判断第一电流是否大于第二电流；在第一电流大于第二电流的情况下，则对第一燃料电池***与第二燃料电池***进行调整。Optionally, after collecting the currents of the first fuel cell system and the second fuel cell system at the same output power, the above method further includes: judging whether the first current is greater than the second current; when the first current is greater than the second current In other cases, adjust the first fuel cell system and the second fuel cell system.
在具体实施过程中，对第一燃料电池***与第二燃料电池***进行调整，包括：确定第一燃料电池***作为下一次车辆启动时的第二燃料电池***；确定第二燃料电池***作为下一次车辆启动时的第一燃料电池***。In the specific implementation process, adjusting the first fuel cell system and the second fuel cell system includes: determining the first fuel cell system as the second fuel cell system when the vehicle is started next time; determining the second fuel cell system as the next fuel cell system The first fuel cell system at a vehicle start.
可以利用第一燃料电池***、第二燃料电池***对应的电流分别对应电流，对第一燃料电池***、第二燃料电池***的性能进行评估，例如，电流越小、性能越好，反之，电流越大、性能越差，进而对双燃料电池***进行调整，以便在下一次车辆启动时优先采用性能较好的燃料电池***，以避免过度使用性能较差的燃料电池***，导致的双燃料电池***整体的使用寿命降低。The performance of the first fuel cell system and the second fuel cell system can be evaluated by using the corresponding currents of the first fuel cell system and the second fuel cell system, for example, the smaller the current, the better the performance; otherwise, the current The larger the performance, the worse the performance, and then adjust the dual fuel cell system so that the fuel cell system with better performance will be used first when the vehicle is started next time, so as to avoid excessive use of the fuel cell system with poor performance, resulting in dual fuel cell system The overall service life is reduced.
步骤S106，在需求功率小于或者等于第一功率阈值的情况下，则控制启动第一燃料电池***，其中，第一燃料电池***的输出功率为需求功率；或者，控制启动除第一燃料电池***以外任意一个第二燃料电池***，其中，任意一个第二燃料电池***的输出功率为需求功率。Step S106, in the case that the required power is less than or equal to the first power threshold, control to start the first fuel cell system, wherein the output power of the first fuel cell system is the required power; or control to start the first fuel cell system Any other second fuel cell system, wherein the output power of any second fuel cell system is the required power.
上述多个燃料电池***可以包括第一燃料电池***，…，第N-1燃料电池***，第N燃料电池***，其中，N的取值大于等于3。在具体实施过程中，除第一燃料电池***以外的其他燃料电池***均可以称为第二燃料电池***。The above multiple fuel cell systems may include a first fuel cell system, ..., an N-1th fuel cell system, an Nth fuel cell system, wherein the value of N is greater than or equal to 3. In a specific implementation process, other fuel cell systems except the first fuel cell system may be referred to as the second fuel cell system.
在具体实施过程中，以双燃料电池***为例，在需求功率小于或者等于第一功率 阈值时，可以控制启动双燃料电池***中的任意一个。需要说明的，可以优先控制启动在性能最好的燃料电池***。In the specific implementation process, taking the dual fuel cell system as an example, when the required power is less than or equal to the first power threshold, any one of the dual fuel cell systems can be controlled to start. It should be noted that the fuel cell system with the best performance can be preferentially controlled to start.
通过上述步骤，可以通过比较车辆启动时的需求功率与燃料电池***的高效率功率区间内的最大功率，确定燃料电池模块的在启动时的输出功率以满足车辆的需求功率，从而实现了在满足车辆的需求功率的同时，减少燃料电池***的运行时间，且使燃料电池***尽量保持在***高效率区间运行，兼顾了燃料电池***的效率和使用寿命的技术效果，进而解决了相关技术中车辆的双燃料电池***在运行中容易导致***效率低、寿命短的技术问题。Through the above steps, the output power of the fuel cell module at startup can be determined to meet the required power of the vehicle by comparing the required power at startup of the vehicle with the maximum power in the high-efficiency power range of the fuel cell system, thereby achieving While reducing the required power of the vehicle, the running time of the fuel cell system is reduced, and the fuel cell system is kept running in the high-efficiency range of the system as much as possible, taking into account the technical effect of the efficiency and service life of the fuel cell system, and then solves the problem of the vehicle in related technologies. The current dual fuel cell system is prone to technical problems such as low system efficiency and short life during operation.
