The utilization of secondary batteries is a major challenge for realizing a low-carbon society. Among them, each raw material manufacturer or each battery manufacturer can improve the quality of raw materials or batteries to be manufactured and reduce the manufacturing workload. It is desirable to reduce the amount of CO ₂ emitted during battery production, and the company is constantly making efforts.

  However, in each raw material manufacturer or each battery manufacturer, for example, it is very difficult to obtain information and knowledge on how the difference in raw materials or the manufacturing method affects the subsequent performance of the battery.

Also, for example, if each raw material manufacturer or each battery manufacturer changes the raw material or the manufacturing method in order to reduce the amount of CO ₂ emitted during battery manufacturing, the change will affect the subsequent performance of the battery. It is also difficult to obtain information and knowledge about the impacts.

Moreover, even if the amount of CO ₂ emitted during battery production is reduced when manufacturing the battery, if the amount of CO ₂ produced including the raw materials is not known, it will be correctly evaluated how much reduction effect has been obtained. I can't. Further, it is necessary to evaluate the reduction effect along the life cycle of the secondary battery, including the amount of CO ₂ emitted when the battery is used in the subsequent battery.

  In addition, it is very beneficial for the user of a battery to be able to know the estimated remaining usable time that indicates how much the battery can be used in the future, and for that purpose, It is effective to obtain not only evaluation but also statistical information of a battery manufactured under the same conditions as the battery to be used, but it is difficult to obtain such information.

Such modifications are possible and within the purview of those skilled in the art.

  In the system configured as described above, the processing procedure will be described with reference to FIGS.

(Raw material information registration)
When the raw material for which each raw material manufacturer is responsible is manufactured and shipped to the shipping destination, the raw material manufacturer's computer 30 accesses the raw material information registration screen of the server 10 via the Internet 12 near the time of shipment. The raw material information to be stored in the raw material database 150 is input. When the raw material information is transmitted to the server 10, the raw material information registration unit 110 of the server 10 registers the raw material information in the raw material database 150 and assigns a raw material ID unique to the system to the raw material manufacturer computer 30. Send ID.

(Raw material manufacturing total work operation, discharge amount of CO ₂ calculation)
Subsequent changes, browsing, and inquiry of the raw material information can be performed using the given raw material ID. For example, when a certain raw material manufacturer wants to know the total raw material manufacturing work required for manufacturing the raw material in charge, the raw material manufacturer computer 30 sends the raw material ID and inquires the server 10 about the total raw material manufacturing work. Make a request.

  When the receiving means of the server 10 receives this request, the raw material manufacturing work amount calculating means 112 of the server 10 performs the process shown in FIG. 11A in response to this request.

  First, the defined process “raw material production work amount” is called with the inquired raw material ID as an argument (S10).

  In the predefined process “raw material production work amount”, as shown in FIG. 11B, the raw material ID obtained as an argument is processed as a focused raw material ID (S20). First, the raw material manufacturing work accumulation is initialized and 0 is set (S22). Based on the raw material ID of interest, the raw materials constituting the raw material ID of interest are extracted from the raw material database 150, and it is determined whether there is any raw material for which the calculation of the raw material manufacturing work has not been completed (S24). If there is an original raw material that has not been calculated, the usage amount of the original raw material is first extracted (S32). Then, the predefined process “raw material manufacturing work amount” is recursively called as the raw material ID of the raw material ID for which the calculation has not been completed (S32). Also, the corresponding “shipment amount” when the raw material ID of the original raw material is the raw material ID of interest is extracted from the raw material database 150 (S36). Then, the product of the return value of the defined process “raw material manufacturing work amount”, the extracted usage amount, and the extracted shipping amount ratio is added to the raw material manufacturing work amount (S38). After that, it is determined again whether there is an uncalculated one (S24). If there is no raw material that has not been calculated, the raw material manufacturing work amount of the raw material of interest is extracted (S26). Then, the raw material manufacturing work is added to the total raw material manufacturing work, and the result is provided as a return value of the predefined process “raw material manufacturing work” (S30).

  Returning to FIG. 11A, the return value of the predefined process “raw material manufacturing work” is substituted into the raw material manufacturing total work (S12), and the raw material manufacturing total work is provided as a result (S14).

  In this way, the total amount of raw material manufacturing work obtained by integration as needed is calculated by adding the work required to manufacture the inquired raw material to the upstream of the raw material supply line that is the further raw material of the raw material. By looking retroactively, more accurate work can be provided to raw material manufacturers.

  When considering a certain raw material, not all raw material manufacturers from upstream to downstream of the raw material supply line are necessarily necessarily able to participate in the battery evaluation system 1 or all of them. In some cases, it is not possible to obtain information on the raw material manufacturing workload of raw materials for some reason or to register. In that case, it is preferable to input as much as possible all the raw material manufacturing work of the raw material further upstream than the raw material manufactured by the raw material manufacturer in the upstream most upstream raw material manufacturer.

Next, the raw material manufacturing emission CO ₂ amount calculation means 114 uses the known function f for converting the obtained raw material manufacturing total work amount to the CO ₂ amount, where f (raw material manufacturing total work amount) = discharge. The amount is converted into the amount of CO ₂ [kg-CO ₂ ] and transmitted to the computer 30 that made the inquiry. Here, the known function f can be a linear function of the total raw material manufacturing work. For example, “Default value f (total raw material production work) stipulated in a ministerial ordinance on the calculation of greenhouse gas emissions associated with the business activities of specified emitters (Ministry of Economy, Trade and Industry Ordinance No. 3 of 2006) = 0. 555 × Raw material production total work, etc. can be used as a known function.

In this way, by providing raw material manufacturers with the amount of CO ₂ emitted by converting the total amount of raw material production work required to manufacture raw materials to CO ₂ amounts, each raw material manufacturer is committed to manufacturing with an emphasis on the environment. Can be urged.

  The browsing and inquiry of the above raw material information can be performed not only from the raw material manufacturer, but also from any computer operated by a person who participates in the present system that has acquired the raw material ID. For example, when a battery manufacturer or user described below manufactures a battery or uses a battery, selection of raw materials with an emphasis on the environment can be promoted.

(Manufacturing battery information registration)
A raw material ID is provided together with the raw material to the battery manufacturer to which the raw material is shipped. When each battery manufacturer manufactures a battery and ships it to its shipping destination, the battery manufacturer's computer 40 accesses the manufacturing battery information registration screen of the server 10 via the Internet 12 near the time of shipment. The manufacturing battery information to be stored in the battery database 152 is input. When the manufactured battery information is transmitted to the server 10, the manufactured battery information registration unit 120 of the server 10 registers in the battery database 152, assigns a battery ID, and transmits the battery ID to the battery manufacturer computer 40. .

  Further, the battery manufacturer transmits the battery characteristic information at the time of shipment or arbitrary inspection of each battery to be used to the server 10 via the Internet 12 by associating the battery ID information and the inspection status information with the battery manufacturer computer 40 via the Internet 12. . When the battery characteristic information is transmitted to the server 10, the product battery information registration 120 registers in the inspection database 156.

(Battery manufacturing total work calculation, exhaust CO ₂ calculation)
Subsequent changes, browsing, and inquiry of manufactured battery information can be made using the assigned battery ID. For example, when the battery manufacturer wants to know the battery manufacturing work required to manufacture the battery, the battery ID is transmitted from the battery manufacturer computer 40 and the server 10 is inquired about the battery manufacturing work.

  When the receiving unit of the server 10 receives this request, the battery manufacturing work amount calculating unit 122 of the server 10 searches the battery database 152 for a record corresponding to the corresponding battery ID in response to the request, The battery production work in the record is extracted. This battery manufacturing work amount is transmitted to the computer 40 that made the inquiry.

  Furthermore, as shown in FIG. 12, the battery manufacturing work calculation means 122 can calculate the battery manufacturing total work taking the total raw material manufacturing work into consideration.

  In FIG. 12, first, as the initial value, the battery manufacturing total work amount is set to 0 (S40), and then a record corresponding to the inquired battery ID is searched with reference to the battery database 152, The battery manufacturing work is extracted (S42) and added to the total battery manufacturing work (S44).

  Further, one of the raw material IDs corresponding to the inquired battery ID and the amount of use thereof are extracted (S46), and the total raw material manufacturing work of the raw material is obtained (S48). The processing for obtaining the raw material manufacturing total work amount is the processing in FIG.

  Further, the shipment amount corresponding to the raw material ID is extracted with reference to the raw material database 150 (S50). Then, using the raw material manufacturing total work amount obtained in step S48, the usage amount extracted in step S46, and the shipping amount extracted in step S50, the raw material manufacturing total work amount x usage amount / shipping amount is calculated (S52). It is added to the total battery manufacturing work (S54). The above processes S46 to S54 are repeated until all raw materials are processed (S56), and the battery manufacturing total work amount is obtained (S58). The battery manufacturing work amount calculation means 122 transmits the battery manufacturing total work amount obtained as a result of the integration to the battery manufacturer side computer 40 that made the inquiry.

  As described above, the total amount of battery manufacturing work obtained by integration is based on the amount of work required to manufacture the battery for which the inquiry was made, going back upstream of the raw material and the raw material supply line. Because of this demand, more accurate work can be provided to battery manufacturers.

  In the raw material database 150, it may be impossible to input a part or all of the raw material manufacturing work volume that cannot be obtained for some reason or cannot be registered. In this case, it is preferable that the battery manufacturing work includes the raw material manufacturing total work that cannot be input.

Next, the battery manufacturing exhaust CO ₂ amount calculation means 124 uses the known function f for converting the calculated battery manufacturing total work amount to the CO ₂ amount f (battery manufacturing total work amount) = battery. It is converted into the amount of CO ₂ discharged during production [kg-CO ₂ ]. In addition, the amount of CO ₂ discharged per unit battery capacity [kg-CO ₂ / Ah] is obtained by dividing the obtained amount of CO ₂ emission during battery production by the corresponding battery capacity in the battery database 152, and / or Dividing the obtained amount of CO ₂ emission during battery production by the corresponding amount of discharged power in the battery database 152 to obtain the amount of discharged CO ₂ per unit battery output energy [kg-CO ₂ / Wh], and / or Then, by dividing the obtained amount of CO ₂ emission during battery production by the corresponding power density in the battery database 152, the amount of emitted CO ₂ per unit power density [kg-CO ₂ / [W / kg]] is obtained. The transmission means of the server 10 transmits the obtained various amounts of CO ₂ to the battery manufacturer computer 40 that made the inquiry.

Thus, cell production during discharge amount of CO ₂ by converting the cell manufacturing total work required for the amount of CO ₂ to produce a battery, the amount of CO ₂ discharged in the production per unit of battery capacity, the unit cell output power amount Since the amount of CO ₂ discharged in per manufacturing and the amount of CO ₂ discharged per unit power can be obtained and provided to the battery manufacturer, the battery manufacturer can be encouraged to make an effort for manufacturing with an emphasis on the environment.
