Currently, the application of power batteries is more widespread from the development of market situation. The power battery is not only applied to energy storage power supply systems such as hydraulic power, firepower, wind power and solar power stations, but also widely applied to electric vehicles such as electric bicycles, electric motorcycles, electronic devices and the like, and a plurality of fields such as military equipment, aerospace and the like. With the continuous expansion of the application field of the power battery, the market demand of the power battery is also continuously expanding.
In the related art, in order to realize the development and the high efficiency of the power battery, designers finish the classification and carding of a chemical system according to the application scene of the battery, the material category, the performance characteristics of the battery and the like. Thus, after the customer puts forward the demand, the designer gives the proper chemical system type as the battery design direction according to the demand by the customer by means of project experience, and the designer also performs the calibration of the chemical system type on some historical battery designs by means of project experience, so as to facilitate the search according to the design scheme of the chemical system dimension
However, such subjective judgment based on personal project experience, selection of the chemical system type is not only inefficient, but also prone to erroneous judgment of the chemical system type. For example, for selecting a chemical system type based on customer demand, problems may arise that fail to meet customer demand or redundancy in system capacity is excessive, resulting in poor battery solution design rationality. For another example, for a history-based battery design selection of a chemical system type, there is a potential for design calibration errors in the chemical system type, reducing the accuracy of retrieving the design in the chemical system dimension.
In order to solve the technical problems, an automatic matching process of a battery chemical system is developed and designed from design description information (requirement description or design scheme description) of a battery, and the output of the type of the battery chemical system is automatically realized by inputting the design description information. Namely, by receiving the design description information and extracting at least one matching parameter based on the design description information, the chemical system type meeting the design description information is screened from a preset system database according to the extracted matching parameter. The output of the chemical system type is obtained by automatic screening from a preset system database based on various matching parameters extracted from the design description information, so that the judgment of the chemical system capacity can be rapidly realized, and the accuracy of the chemical system selection can be improved.
If the design description information is the customer requirement, the finally screened chemical system type can meet the customer requirement, and the accuracy is high, so that the condition of excessive system capacity can be reduced, and the battery scheme generated by taking the chemical system type as the design direction has certain rationality.
If the design description information is the history scheme description information, the chemical system type calibration of the history scheme can be rapidly realized, and the chemical system classification optimization is facilitated.
The method for determining the battery chemical system disclosed by the embodiment of the application is not only suitable for determining the system direction in the requirement-raising stage of a user before battery design development, thereby laying a foundation for automatic design of the battery, but also suitable for the completed historical battery design, and is beneficial to the convergence retrieval of the dimension of the chemical system by calibrating the chemical system design scheme.
The above-mentioned battery may be a battery product of a battery module, a battery pack, a battery cell, or the like, which helps to improve the rationality of designing a battery scheme by obtaining a battery chemistry system type that satisfies the needs of users.
In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.
Fig. 1 is a flowchart of an embodiment of a battery chemistry system determination method according to an exemplary embodiment of the present application, the battery chemistry system determination method comprising the steps of:
step 101: and receiving the design description information of the battery.
Step 102: at least one matching parameter is extracted based on the design description information.
Step 103: and screening chemical system types meeting the design description information from a preset system database according to the extracted matching parameters.
The execution body of the embodiment of the application may be an electronic device, and the electronic device may include, but is not limited to, a terminal, a server, or the like.
In the embodiment of the present application, the design description information may be requirement description information or design plan description information. The requirement description information is the requirement description of the battery performance index input by the client according to the battery application scene before the battery scheme design is carried out, and the design scheme description information is the design content of the battery scheme which is completed according to the requirement of the client. The description of the requirements of the battery is largely a macroscopic parameter description of the battery parameters compared to the design description, which will be more specific, such as what positive electrode material is used, what negative electrode material is used, what upper voltage limit of the battery is, etc.
However, the design description information belongs to a large-section text description, and can be subjected to structural decomposition to extract structural parameters suitable for standard screening of chemical system types, namely matching parameters. The extracted matching parameters represent specific requirements of the anode and cathode properties of the battery or a certain performance index of the battery, such as anode and cathode materials, charging capability, service life type, weight energy density, volume energy density and the like.
The mapping relation between different parameter intervals corresponding to different matching parameters and a system list is recorded in a preset system database, and each system list comprises a plurality of chemical system types supporting the corresponding parameter intervals. For example, for the performance index of battery service time, the mapping relation between the life span of the normal life and the system list and the mapping relation between the life span of the long life type and the system list are recorded in the system database. Therefore, the chemical system type meeting the design description information can be obtained by screening from a preset system database according to the extracted matching parameters.
It should be noted that, for the design description information is the requirement description information, since the requirement description information of the user is the performance requirement of the whole battery, there is no specific requirement of adopting chemical materials and positive and negative electrode components for the battery, so the types of chemical systems meeting the requirement of the user can be multiple. And for the design description information, the scheme description information is more detailed to describe the battery, so that the number of chemical system types corresponding to the design scheme is 1.
The chemical system type is classified according to the application scene, the material class and the performance characteristics of the battery. The representation of the chemical system type may include a number of different classification information, such as the positive system class NCM (ternary materials including nickel (Ni), cobalt (Co), and manganese (Mn)), LFP (LiFePO) 4 Lithium iron phosphate), LMO (lithium manganate) and the like are different chemical system classes, and NCM5 system, NCM8 system and the like are different chemical system subclasses, and also the same positive electrode system class, different negative electrode system class, such as different graphite negative electrode types, are also different chemical systems.
Alternatively, the representation of the chemical system type may comprise: four system classification information of voltage + positive electrode system type + negative electrode system type + charge rate capability, for example 4.2v NCM5 system XX graphite 1.4C.
Based on the above description, for example, assuming that the design description information input by the user is the requirement description information, the matching parameters extracted from the requirement description information are: required freeze time→ 20230510; the required charging capacity (namely, the fast charging capacity) to SOC (State Of Charge) range is 20% -80%, and charging is completed within 40 min; demand life-conventional life; energy density → 230Wh/Kg,530Wh/L, the types of chemical systems screened from the systems database are: (1) 4.2V NCM5 is XX graphite 1C; (2) 4.2V NCM5 is XX graphite 1.4C; (3) 4.25V NCM8 is XX graphite 1.4C.
For another example, assuming that the design description information input by the user is the scheme description information, the matching parameters extracted from the scheme description information are: the positive electrode material is ternary A; the negative electrode material is graphite B; the energy density is 230Wh/Kg,520Wh/L; the upper voltage limit is 4.4V; the application scene is BEV (Battery Electric Vehicle, pure electric vehicle); the equivalent quick charge rate is 2.2C. The type of chemical system screened from the system database is 4.4V NCM5 series quick-charging graphite grade B.
So far, through the above-mentioned battery chemical system determining process shown in fig. 1, the output of the chemical system type meeting the design description information is automatically completed by inputting the design description information, and because the output of the chemical system type is obtained by automatically screening from a preset system database based on various matching parameters extracted by the design description information, the judgment of the chemical system capacity can be quickly realized, and the accuracy of the chemical system selection can be further improved.
In some embodiments of the present application, extracting at least one matching parameter based on the design description information includes:
inquiring the word matched with the preset parameter name in the design description information, determining the data type of the value corresponding to the preset parameter name if the preset parameter name is inquired, and extracting the word closest to the word and belonging to the data type from the design description information as a matching parameter.
The preset parameter names are names of battery performances generally proposed by user demands, such as freezing time, energy density, fast charge capacity, battery life, upper voltage limit, positive electrode material, negative electrode material and other parameter items. Therefore, the extraction of the matching parameters can be performed according to each preset parameter name, if the word matched with the preset parameter name is queried in the design description information, the corresponding parameter value is further extracted around the word by combining the data type corresponding to the preset parameter name, and if the word matched with the preset parameter name is not queried in the design description information, the user is not described on the battery performance of the parameter, and then the matching of the next preset parameter name is performed.
The word segmentation of the design description information can adopt related technology to carry out word segmentation processing on the design description information so as to facilitate the matching of parameter names and parameter values.
Therefore, each preset parameter name corresponds to one matching parameter, the preset parameter names are inquired in the user design description information, if the user is inquired, the user is required to have the parameter corresponding to the parameter names, and the corresponding matching parameters can be accurately extracted by searching around the corresponding word of the design description information according to the data type corresponding to the parameter names and the nearest distance condition between the parameter names and the parameter values.
Before screening the chemical system types meeting the design description information from the preset system database according to at least one matching parameter, the system database needs to be built so as to be used for screening the chemical system types.
In some embodiments of the present application, the building process of the architecture database includes:
the method comprises the steps of obtaining a plurality of chemical system types and battery product parameters corresponding to each chemical system type, determining parameter intervals of batteries produced by the chemical system types in terms of different performances according to the corresponding battery product parameters, and storing mapping relations between the parameter intervals of different performances and the corresponding chemical system types into a system database, so that structural establishment of the system database is completed, and management of the chemical system types is more standard.
The obtained battery product parameters refer to electrical performance indexes of the battery, such as battery life type, freezing time of battery design, voltage range, positive electrode system type, negative electrode system type, quick charge capability, weight energy density range, volume energy density range and the like. For the same performance index, a plurality of parameter intervals can be obtained, and the chemical system type to which each parameter interval belongs can be a plurality of, so that in the system database, the parameter intervals with different performances are corresponding to a system list, and the system list comprises a plurality of chemical system types.
For example, in the system database, it is assumed that the battery life type has two parameter intervals of a normal life and a long life, the system list corresponding to the normal life includes a chemical system type 1 and a chemical system type 2, and the system list corresponding to the long life includes a chemical system type 3 and a chemical system type 4.
In some embodiments of the present application, selecting chemical system types from a preset system database that satisfy design description information according to at least one matching parameter includes:
and screening at least one system list from a preset system database according to each matching parameter, and then performing intersection processing on the chemical system types in each system list to obtain the chemical system types meeting the design description information.
The chemical system types in the system list only meet the requirements of corresponding matching parameters, and the system list screened by different matching parameters is intersected, so that the finally output chemical system types can meet the battery design, and the accurate matching of the chemical system capacity is realized.
It should be noted that, for the chemical system types satisfying the requirement description information, there may be a plurality of chemical system types, and for the design scheme description information, if more than one chemical system type is obtained through intersection processing of the system list, further screening may be performed based on other matching parameters in the design scheme description information, so that the design scheme finally calibrates one chemical system type.
In an alternative embodiment, for the process of screening at least one system list from the preset system database according to each matching parameter, a parameter interval to which the matching parameter belongs is determined based on the preset system database and a target decision corresponding to the matching parameter, and then the system list corresponding to the parameter interval is acquired from the preset system database.
In this embodiment, the system matching conditions of the matching parameters in the preset system database are set in the target decisions, and based on the above manner, the system list adopted in different parameter intervals of the matching parameters is recorded in the preset system database, for example, the matching parameters are required freezing time, and the system matching conditions set in the corresponding target decisions are system lists corresponding to the freezing time earlier than the required freezing time in the preset system database. Therefore, the system database and the target decision are used for determining the parameter interval to which the matching parameter belongs, and a system list conforming to the matching parameter can be obtained through screening.
Taking design description information as requirement description information as an example, an acquisition example of a system list of four matching parameters is given:
1. and under the condition that the matching parameters are the required freezing time, acquiring a system list corresponding to the freezing time earlier than the required freezing time from a preset system database.
2. Under the condition that the matching parameters are the required energy density, acquiring a system list corresponding to an energy density range to which the required energy density belongs from a preset system database; the required energy density may be any one of the weight energy density and the volume energy density of the battery.
3. And under the condition that the matching parameters are the required life, acquiring a system list corresponding to the life type to which the required life belongs from a preset system database.
4. Under the condition that the matching parameters are required charging capacity, the required charging capacity is converted into required charging multiplying power, and a system list corresponding to a charging multiplying power range to which the required charging multiplying power belongs is obtained from a preset system database; the required charging capability includes a start SOC, a stop SOC, and a charging time, and the charging rate formula is calculated by using the start SOC, the stop SOC, and the charging time: c= (end SOC-start SOC) ×60/charge time min.
In the above example, because the design description information is specifically a customer requirement description before the solution design is performed, the matching parameters include a requirement freezing time, a requirement energy density, a requirement life, a requirement charging capability and the like, which are all requirements of users on different performance aspects of the battery, so that the obtained system list corresponding to each parameter interval is equivalent to standard comparison screening on different performances of the chemical system, and is favorable for realizing comprehensiveness of chemical system type screening.
It should be noted that the above four matching parameters are only exemplary, and other attribute screening decisions of the chemical system, such as application scenarios, may be set.
Taking the design description information as the scheme description information as an example, an acquisition example of a system list of four matching parameters is given:
1. and under the condition that the matching parameters are positive electrode material information, acquiring a system list corresponding to the positive electrode system type to which the positive electrode material information belongs from a preset system database. Alternatively, the positive electrode system type to which the positive electrode material information belongs can be determined by querying a preset positive electrode material database, so that a system list corresponding to the corresponding positive electrode system type can be obtained from the system database.
2. And under the condition that the matching parameters are negative electrode material information, acquiring a system list corresponding to the negative electrode system type to which the negative electrode material information belongs from a preset system database. Alternatively, the negative electrode system type to which the negative electrode material information belongs can be determined by querying a preset negative electrode material database, so that a system list corresponding to the corresponding negative electrode system type can be obtained from the system database.
3. And under the condition that the matching parameters are the designed energy density, acquiring a system list corresponding to the energy density range to which the designed energy density belongs from a preset system database. The design energy density may be any one of the weight energy density and the volume energy density of the battery.
4. And under the condition that the matching parameter is the upper voltage limit, acquiring a system list corresponding to the voltage range to which the upper voltage limit belongs from a preset system database.
Because the design description information is a battery design scheme, specific parameters such as the use of anode and cathode materials of the battery, the upper limit of voltage and the like exist in the design scheme, and the matching parameters comprise the information of the anode and cathode materials, the design energy density, the upper limit of voltage and the like, so that the requirements on different performances of the battery are met, the specific design materials are also provided, and the acquired system list is favorable for realizing the comprehensiveness of the type screening of the chemical system.
In some embodiments of the present application, after screening the chemical system type that satisfies the design description information, in the case where the design description information is the demand description information, since the chemical system type can guide the design direction of the battery scheme, the battery design scheme that satisfies the demand description information may be generated according to the chemical system type, so as to improve the rationality of the battery design scheme.
