And establishing and storing the mapping relation among the battery design scheme, the updated battery design scheme and the updated engineering bill of materials.
In this embodiment, when the battery design scheme is updated by using the substitute material parameter, the substitute material may be directly used to replace the set material parameter matching with the substitute material parameter in the battery design scheme, that is, the set material parameter in the battery design scheme is deleted, and the substitute material parameter is stored as a new set material parameter in the battery design scheme, so as to obtain the updated battery design scheme.
It should be understood that the process of generating the updated engineering bill of materials of the updated battery design by using the engineering bill of materials template in this embodiment is similar to the process of generating the engineering bill of materials of the battery design by using the engineering bill of materials template, so as to prevent redundancy, and the description will not be repeated here.

And calling each template in the engineering bill of materials template according to the execution sequence to process the design parameters and the material parameters, and generating an engineering bill of materials corresponding to the battery design scheme.
In this embodiment, each of the engineering bill of materials templates is used to describe a hierarchical relationship between the material parameters involved in the template. Still referring to fig. 2, the engineering bill of materials template includes five templates, the first template indicates a hierarchical relationship between the positive electrode sheet and the positive electrode current collector, the positive electrode active layer and the positive electrode tab, the second template indicates a hierarchical relationship between the negative electrode sheet and the negative electrode current collector, the negative electrode active layer and the positive electrode tab, the third template indicates an interlayer relationship between the bare cell and the positive electrode sheet, a membrane and the negative electrode sheet, the fourth template indicates a hierarchical relationship between the case and the case material, and the fifth template indicates a hierarchical relationship between the battery and the case and the bare cell.
Based on the description of the above hierarchical relationship, it can be found that the material parameters included in the battery design scheme depend on each other, and one material parameter may be an intermediate value result of another material parameter, so in order to improve the efficiency of generating the engineering bill of materials, the finally determined execution sequence may be that the execution sequence of the template corresponding to the material parameter with the lower level in the parameter hierarchical relationship is earlier than the execution sequence of the template corresponding to the material parameter with the higher level, so that when generating the engineering bill of materials with the higher level, the calculated engineering bill of materials with the lower level of material parameters may be adopted. Still in combination with the foregoing five template examples included in fig. 2, the execution sequence of the five finally determined templates may be that the execution of the first template and the second template is not sequentially divided, the two templates may be executed in parallel, the execution sequence of the third template is later than the execution sequence of the first template and the second template, the execution sequence of the fourth template is not sequentially divided from the execution sequence of the first template, the second template and the third template, and the execution sequence of the third template may be earlier than the first three templates, later than the first three templates, or may be executed in parallel with any one of the first three templates. The fifth template is executed in the latest order.

It should be appreciated that the execution order of the templates in the engineering bill of materials template is marked in the execution order, so that when selecting the target template to be invoked currently, it can be determined based on the execution order of the template that was invoked last time. For example, the engineering bill of materials template includes 3 templates, namely, template 1, template 2 and template 3, the execution sequence of the three templates is respectively that the first call of the template 1, the second call of the template 2, the third call of the template 3, and assuming that the template which is called last time is the template 2 and the template 1 is the template which is called before the template 2, it can be determined that the target template to be called currently should be the template 3.
