A fuel cell is a power generation device that directly converts chemical energy present in a fuel and an oxidant into electrical energy. In order to make the fuel cell more reliable and durable, performance tests on the fuel cell system are required.

In the related art, a simulated stack is obtained by performing simulation on a stack of a fuel cell system, and a performance test is performed on the simulated stack to obtain test data or simulate a stack fault under certain conditions. However, the above scheme cannot comprehensively obtain test data of the fuel cell system.

In order to comprehensively obtain test data of a fuel cell system, embodiments of the present invention provide a simulation test method, apparatus, device and storage medium for a fuel cell system, and the present disclosure will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fig. 1 is a system architecture diagram of a simulation system of a fuel cell according to this embodiment, where the simulation system 100 includes a plurality of device simulation models, such as the control simulation model 110 and a component simulation model of a subsystem simulation model shown in fig. 1 (fig. 1 illustrates a subsystem simulation model 121 and a subsystem simulation model 122; the subsystem simulation model 121 includes a component simulation model 1211, a component simulation model 1212, and a component simulation model 1213, and the subsystem simulation model 122 includes a component simulation model 1221, a component simulation model 1222, a component simulation model 1223, and a component simulation model 1224, for example, in practical applications, the number of subsystem simulation models and the number of component simulation models of each subsystem simulation model may be more or less), and a stack simulation model 130.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 2 is a schematic flow chart of a simulation test method for a fuel cell system according to an embodiment of the present invention, which is applied to a simulation test apparatus for a fuel cell system, and as shown in fig. 2, the method may include:

step 201: based on a test instruction for the fuel cell, an initial parameter in the test instruction is determined.

For example, the fuel cell system simulation test equipment determines the initial parameters contained in the test instruction after receiving the test instruction for the fuel cell. The type of the initial parameter may be determined according to the type to be tested and the parameter type of the interface, for example: the temperature and pressure of some devices of the fuel cell need to be tested, and the types of input and output parameters of the interfaces of the devices comprise the temperature and the pressure, and the initial parameters can comprise the initial temperature and the initial pressure.

The examples herein are only for illustrating that the type of the initial parameter is related to the type of the interface and the type of the test required, and are not limited to the type of the initial parameter, the type of the test required, and the type of the interface in this embodiment.

The present embodiment does not limit the manner of receiving the test instruction for the fuel cell, for example:

1) Receiving a test instruction sent by a control terminal through a Local Area Network (LAN), a Wireless Local Area Network (WLAN) or other networks;

2) Receiving a test instruction through a User Interface (UI for short);

3) Receiving a voice test instruction through a voice receiving device;

4) And responding to the triggering of the target key, and determining a test instruction corresponding to the target key according to the preset corresponding relation between the key and the instruction.

The above receiving manners are only examples, and other manners for receiving the test command for the fuel cell are also applicable to the embodiments of the present invention, and are not described herein again.

Step 202: and determining the simulation model to be tested corresponding to the identifier contained in the test instruction from a device simulation model of the simulation system of the fuel cell.

The simulation model to be tested is a part or all of a control simulation model, a part or all of a subsystem simulation model and a cell stack simulation model which are contained in the device simulation model, the control simulation model is connected with the part or all of the subsystem simulation model, and the cell stack simulation model is connected with the part of the subsystem simulation model.

In this embodiment, for a test instruction, the identifier included in the test instruction may be an identifier of one or more of the control simulation model, the component simulation model of the subsystem simulation model, and the stack simulation model, which is described by taking the simulation system in fig. 1 as an example, for example:

1) The test instruction only carries the identifier of the component simulation model 1212;

2) The test instructions carry an identification of the component simulation model 1222, an identification of the stack simulation model 130, and an identification of the component simulation model 1223.

The above two types of identifiers included in the test instruction are merely exemplary, and descriptions about possible identifiers included in other test instructions are omitted here.

Step 203: and inputting the initial parameters into an input interface of the simulation system, and acquiring test parameters of the device model to be tested in the test process of the simulation system.

In this embodiment, the initial parameters are input into an input interface of the simulation system, the simulation system enters a test process, the device simulation models receive the input parameters through the interfaces thereof, and output corresponding parameters through the interfaces after processing, so as to obtain test parameters (parameters input or output by the interfaces) of the device model to be tested.

The initial parameters include initial standard parameters corresponding to the test parameters and control parameters, after the initial parameters are input into an input interface of the simulation system, the standard parameters enter an initial component simulation model of each subsystem simulation model, the initial component simulation model processes the standard parameters and outputs the standard parameters through an interface of the initial component simulation model, the standard parameters output by the interface of the previous component simulation model are used as the standard parameters input by the interface of the connected next component simulation model or the connected cell stack simulation model, and the standard parameters output by the cell stack model interface are used as the input standard parameters of the interface of the connected next component simulation model. And the control parameters enter the input parameters of the control simulation model interface, and the control simulation model sends control instructions to the corresponding component simulation model through the interface based on the control parameters.

It can be understood that the standard parameters input by the interface of the corresponding component simulation model may also be input to the interface of the control simulation model, and the control simulation model interface sends a control instruction to the corresponding component simulation model based on the control parameters and the standard parameters, so as to implement closed-loop control.

Optionally, the subsystem simulation model includes a hydrogen gas circuit subsystem simulation model, an air circuit subsystem simulation model, and a cooling gas circuit subsystem simulation model.

According to the scheme, the device simulation model of the fuel cell simulation system comprises a control simulation model, each part simulation model of a subsystem simulation model and a pile simulation model, and the simulation system is tested to obtain the test parameters of one or more device simulation models, so that more comprehensive test data can be obtained; in addition, the device simulation model is a virtual model obtained by setting the input and output parameter types of the interface in the initial device model of the fuel cell based on the preset interface parameter types and simulating the initial device model according to the preset performance parameters, so that each device simulation model can be tested under the condition of no solid parts, the device of the fuel cell is not damaged, the test cost is reduced, and the simulation test parameters of each part of the controller and the subsystem and/or the electric pile under certain limit conditions can be obtained through simulation test to simulate the related faults of each part of the controller and the subsystem and/or the electric pile.

The simulation system may be built by the method shown in fig. 4, and as shown in fig. 4, the simulation system building method may include:

step 401: and setting the input and output parameter types of the interfaces in the initial device model of the fuel cell based on the preset interface parameter types.

The initial device model is a code or a graph which is formed for a device of the fuel cell and has no device performance and no interface parameter type. In this embodiment, in order to ensure that the test process of the simulation system is performed, the input and output parameter types of the interface in the initial device model need to be set.

Illustratively, the input/output parameter types of the interfaces of each initial device model are preset according to the actual application scenario, and the input/output parameter types of the interfaces in the initial device models are correspondingly set to be the preset parameter types.

Step 402: and simulating the initial device model according to preset performance parameters.

In order to make the simulation system as close as possible to the actual fuel cell, the present embodiment needs to assign the device performance to the corresponding initial device model.

For example, the preset performance parameter is preset according to a device of the fuel cell, and an initial device model corresponding to the device is simulated according to the preset device performance parameter.

The present embodiment does not limit the manner of obtaining the preset performance parameter, for example: the preset performance parameters are determined by inquiring production information of the device, performance information corresponding to the device model or other related information and the like.

step 501: and setting the input and output parameter type of the interface in the initial device model based on the preset interface parameters through at least one target software in preset software.

In this embodiment, the interface of the initial device model may be set by one or more target software, for example:

1) When the simulation effect of one piece of simulation software in the preset software on all the devices of the fuel cell is good, the input and output parameter types of the interfaces in all the initial device models can be set through the one piece of simulation software, and then all the initial device models are simulated through the one piece of simulation software in step 502.

2) When any one of the preset software can not simulate all the devices of the fuel cell well, the input and output parameter types of the interfaces in different initial device models can be set through a plurality of simulation software, and then the corresponding initial device models are simulated through the plurality of simulation software in step 502.

Step 502: and simulating the initial device model according to the preset performance parameters through the target software.

The specific implementation manner of step 502 may refer to the above embodiments, and is not described herein again.

step 601: and setting input and output parameter types of interfaces of target initial device models in the initial device models based on the preset interface parameters through the first target software, and setting input and output parameter types of interfaces of other initial device models except the target initial device models based on the preset interface parameters through the second target software.

In this embodiment, for a situation that any one of the preset software cannot better simulate all the devices of the fuel cell, a device simulation model corresponding to a target initial device model may be obtained by simulating and interface-setting a target initial device model through preset first target software, and a device simulation model corresponding to another initial device model may be obtained by simulating and interface-setting another initial device model through second target software, which is also described with reference to the simulation system in fig. 1 as an example, for example:

the first target software has a good simulation effect on components corresponding to each component simulation model in the fuel cell stack, controller and subsystem simulation model 121, the initial stack model, the initial control model and each initial component model in the subsystem simulation model 121 are used as target initial device models, and the target initial device models are simulated and interface-set to obtain a control simulation model 110, a component simulation model 1211, a component simulation model 1212, a component simulation model 1213 and a stack simulation model 130;

the second target software has a better effect on simulating other devices of the fuel cell, and the second target software is used for simulating other initial devices and setting interfaces to obtain a component simulation model 1221, a component simulation model 1222, a component simulation model 1223 and a component simulation model 1224.

The division of the target initial device model is only an example and is not a limitation to the embodiment.

Step 602: and simulating the target initial device model according to the preset performance parameters of the target initial device model through the first target software, and simulating the other initial device models according to the preset performance parameters of the other initial device models through the second target software.

The specific implementation manner of step 602 may refer to the foregoing embodiments, and is not described herein again.

The device simulation model for setting the interface parameters is obtained through the above steps 601 and 602.

The present embodiment does not limit the sequence of the step 601 and the step 602.

Step 603: sending device simulation model data corresponding to the other initial device models to the first target software through the second target software, and building all device simulation models into the simulation system through the first target software based on a preset connection relation;

or the device simulation model data corresponding to other initial device models are sent to other software except the target software in the preset software through second target software, the device simulation model data corresponding to the target initial device model are sent to other software through first target software, and all device simulation models are built into the simulation system through other software based on a preset connection relation.

In this embodiment, a simulation system may be built through first target software, second target software, or any other software, and the example that the first target software and the other software build the simulation system based on a graph and the second target software builds the simulation system based on a code is described as follows:

1) The second target software sends codes of device simulation models corresponding to other initial device models to the first target software, the first target software analyzes the codes into graphs of the device simulation models corresponding to other initial device models, and the graphs of all the device simulation models are built into a simulation system based on a preset connection relation;

2) The first target software sends the graph of the device simulation model corresponding to the target initial device model to second target software, the second target software analyzes the graph into codes of device simulation models corresponding to other initial device models, and the codes of all device simulation models are built into a simulation system based on a preset connection relation;

3) The first target software sends the graphs of the device simulation models corresponding to the target initial device models to other software, the second target software sends the codes of the device simulation models corresponding to the other initial device models to the other software, the other software analyzes the codes into the graphs of the device simulation models corresponding to the other initial device models, and the graphs of all the device simulation models are built into a simulation system based on the preset connection relation.

The above are only examples of several ways of constructing the simulation system, and other ways of constructing the simulation system are also applicable to the embodiment.

According to the scheme, the device simulation model corresponding to the target initial device model is obtained by simulating and interface setting the target initial device model through the first target software, the device simulation model corresponding to the other initial device model is obtained by simulating and interface setting the other initial device model through the second target software, and the problem that the simulation effect of the first target software on some devices is poor or the simulation effect of the second target software on some devices is poor, so that the problem that the simulation effect of a simulation system is poor is solved. In addition, the device simulation model can be built into a simulation system through any one of the first target software, the second target software or the preset software, so that the building of the simulation system is more flexible, and the requirements of different scenes are met.

Fig. 7 is a schematic flow chart of still another simulation system building method provided in an embodiment of the present invention, where an initial device model in this embodiment includes an initial control model, initial component models of an initial subsystem model, and an initial stack model, and as shown in fig. 7, the method may include:

step 701: and setting input and output parameter types of the interface of the initial electric pile model and the standardized interface of each initial component model based on the standardized type in the preset interface parameters, wherein the standardized type comprises at least one of pressure, temperature, working medium flow and water vapor flow.

In this embodiment, the initial component simulation model of the simulation system outputs the standard parameters through the standardized interface after processing the standard parameters, the standard parameters output by the standardized interface of the previous component simulation model are used as the standard parameters input by the standardized interface of the connected next component simulation model or the connected stack simulation model, and the standard parameters output by the standardized interface of the stack model are used as the input standard parameters of the standardized interface of the connected next component simulation model. If the input and output parameter types of the interface of the initial cell stack model and the standardized interface of each initial component model are not set based on the standardized types, the output parameter type of the standardized interface of the previous component simulation model may be different from the input parameter type of the standardized interface of the connected next component simulation model/the input parameter type of the interface of the connected cell stack simulation model in the test process, and the like, and then the test process can be completed only by performing interface conversion. Therefore, these interfaces need to be set up based on standardized types, such as:

and setting the input and output parameter types of the interface of the initial electric pile model and the standardized interface of each initial component model as pressure, temperature, working medium flow and water vapor flow.

Step 702: and setting the input and output parameter types of the interface of the initial control model based on the control types in the preset interface parameters, and setting the input parameter types of the control interfaces of part or all of the initial component models.

In this embodiment, the control simulation model needs to send a control instruction to part or all of the component simulation models, and therefore, it is also necessary to set input/output parameter types of interfaces of the initial control model, and set input parameter types of control interfaces of the part or all of the initial component models, for example:

the input and output parameter types of the interface of the initial control model are set as output power and rotating speed, the input parameter type of the control interface of one initial component model connected with the initial control model is set as output power, and the input parameter type of the control interface of the other initial component model connected with the initial control model is set as rotating speed.

The above setting manner is only an example, and other setting manners are also applicable to the embodiment of the present invention, and are not described herein again.

Step 703: and simulating the initial device model according to preset performance parameters.

Step 704: and building the device simulation model into a simulation system based on a preset connection relation.

Steps 703-704 are implemented in the same manner as steps 402-403, and are not described herein again.

According to the scheme, the input and output parameter types of the interfaces of the stack simulation model are set on the basis of the standardized types, the input and output parameter types of the standardized interfaces of each part simulation model are set on the basis of the standardized types, and therefore the problems of complexity and time consumption caused by the fact that interface conversion is needed to complete the test process under the conditions that the output parameter type of the standardized interface of the previous part simulation model is different from the input parameter type of the standardized interface of the connected next part simulation model/the input parameter type of the interface of the connected stack simulation model in the test process are avoided. The input and output parameter types of the interface of the control simulation model are set for the interface of the initial control model based on the control type, and the input parameter types of the control interfaces of part or all of the part simulation models are set for the control interfaces of the corresponding part or all of the initial part models based on the control type, so that the part or all of the part simulation models can timely and accurately obtain the control instructions sent by the control simulation model in the test process.
