蓄電池管理システムBattery Management System

　本発明は、蓄電池の不具合をユーザから受けたときの解析から通知までを管理するシステムに関する。 The present invention relates to a system that manages everything from analysis to notification when a user reports a malfunction in a storage battery.

　特許文献１には、リチウムイオン二次電池の診断システムが記載されている。特許文献１の診断システムは、リチウムイオン二次電池の製造工程における品質情報を収集してデータベースに蓄積する。特許文献１の診断システムは、使用中のリチウムイオン二次電池モジュールの稼働実績情報を収集してデータベースに蓄積する。 Patent Document 1 describes a diagnostic system for lithium-ion secondary batteries. The diagnostic system of Patent Document 1 collects quality information from the manufacturing process of lithium-ion secondary batteries and stores it in a database. The diagnostic system of Patent Document 1 collects operational performance information from lithium-ion secondary battery modules in use and stores it in a database.

　特許文献１の診断システムは、稼働実績を監視して異常が発生した場合に、異常要因が製造要因か使用環境要因かを切り分けて、診断レポートを作成する。 The diagnostic system in Patent Document 1 monitors operational records, and when an abnormality occurs, it determines whether the cause of the abnormality is a manufacturing factor or a factor in the usage environment, and creates a diagnostic report.

特開２０１１－１００６９１号公報JP 2011-100691 A

　しかしながら、特許文献１の診断システムは、畜電池モジュールの製造から運用までを一気通貫で管理するシステムである。したがって、畜電池モジュールを製造するメーカと、蓄電池モジュールが搭載された製品を販売するメーカが異なる場合は、特許文献１の診断システムを適用することが難しい。 However, the diagnostic system in Patent Document 1 is a system that manages the entire process from the manufacture to the operation of the battery module. Therefore, if the manufacturer that manufactures the battery module is different from the manufacturer that sells the product equipped with the battery module, it is difficult to apply the diagnostic system in Patent Document 1.

　また、特許文献１の診断システムでは、劣化度を解析することなく不具合を判定しているため、単に蓄電池の劣化が進んでいるだけなのか、故障のような不具合が発生しているのかを明確にできなかった。 In addition, the diagnostic system in Patent Document 1 determines the malfunction without analyzing the degree of deterioration, so it is not possible to clearly determine whether the storage battery is simply deteriorating or whether a malfunction such as a breakdown has occurred.

　この発明の目的は、蓄電池の不具合をユーザから受けたときに、劣化が進んでいるだけなのか、製造時要因を含む不具合が発生しているのか判定して通知する充電池管理システムを提供することにある。 The object of this invention is to provide a rechargeable battery management system that, when a user reports a malfunction in a storage battery, determines whether the battery is simply deteriorating or whether a malfunction has occurred that may have been caused by manufacturing factors, and notifies the user.

　この発明の蓄電池管理システムは、検査装置、第１のデータベース、第２のデータベース、および中央管理装置を備える。検査装置は、蓄電池モジュールのＳＯＣ－ＯＣＶ特性を測定して、ＳＯＣ－ＯＣＶ特性を含む蓄電池モジュールの使用状態の検査結果を生成する。第１のデータベースは、検査装置による蓄電池モジュールの使用状態の検査結果を蓄積する。第２のデータベースは、蓄電池モジュールに使用されている電池セルの製造時における品質情報を蓄積する。中央管理装置は、第１のデータベースおよび第２のデータベースにアクセス可能である。中央管理装置は、ＳＯＣ－ＯＣＶ特性から蓄電池モジュールの劣化度を解析するとともに、劣化度の解析結果、使用状態の検査結果、および品質情報に基づいて蓄電池モジュールの不具合情報を生成して蓄積する。 The battery management system of the present invention includes an inspection device, a first database, a second database, and a central management device. The inspection device measures the SOC-OCV characteristics of the battery module and generates inspection results of the usage state of the battery module including the SOC-OCV characteristics. The first database stores the inspection results of the usage state of the battery module by the inspection device. The second database stores quality information at the time of manufacture of the battery cells used in the battery module. The central management device can access the first database and the second database. The central management device analyzes the deterioration level of the battery module from the SOC-OCV characteristics, and generates and stores defect information for the battery module based on the analysis results of the deterioration level, the usage state inspection results, and the quality information.

　中央管理装置は、劣化度の解析結果から、電池セルの製造時の品質に起因する不具合があると判定した場合、電池セルの品質情報を第２のデータベースから取得する。中央管理装置は、不具合情報のうち品質情報に関連する内容を第１のデータベースに通知し、劣化度の解析結果を検査装置に通知する。 If the central management device determines from the degradation analysis results that there is a defect caused by the quality at the time of manufacturing the battery cell, it obtains quality information about the battery cell from the second database. The central management device notifies the first database of the content of the defect information related to the quality information, and notifies the inspection device of the degradation analysis results.

　この構成では、蓄電池モジュールの不具合を受け付けると、ＳＯＣ－ＯＣＶ特性を測定することで劣化度を解析し、劣化度の解析結果を含めて、製造時要因を含む不具合であるか否かを判定する。 In this configuration, when a malfunction of the storage battery module is received, the degree of degradation is analyzed by measuring the SOC-OCV characteristics, and based on the results of the analysis of the degree of degradation, it is determined whether or not the malfunction is due to manufacturing factors.

　この発明によれば、蓄電池の不具合をユーザから受けたときに、劣化が進んでいるだけなのか、製造時要因を含む不具合が発生しているのかを判定して通知できる。 With this invention, when a user reports a malfunction in their storage battery, it is possible to determine whether the battery is simply deteriorating or whether a malfunction has occurred that may have been caused by manufacturing factors, and then notify the user.

The central management unit 20 must have at least the function of analyzing the degree of deterioration of the battery cells using the SOC-OCV characteristics and the function of determining defects in the storage battery module, which will be described later.

　中央管理装置２０は、稼働実績管理ＤＢ３１および稼働実績管理ＤＢ３２に対してデータ通信を行うことができる。言い換えれば、中央管理装置２０は、稼働実績管理ＤＢ３１および稼働実績管理ＤＢ３２に対してアクセス可能である。 The central management unit 20 can communicate data with the operation history management DB 31 and the operation history management DB 32.

　（各種情報の取得、蓄積）
　図２は、蓄電池モジュールの不具合判定に利用する各種情報の流れの一例を示す図である。図２では、検査装置４１１、検査装置４１２、検査装置４２１、および検査装置４２２から中央管理装置２０への情報の流れを示す。 (Acquisition and storage of various information)
2 is a diagram showing an example of the flow of various information used to determine a defect in a storage battery module. In FIG. 2, the flow of information from the inspection device 411, the inspection device 412, the inspection device 421, and the inspection device 422 to the central management device 20 is shown.

　検査装置４１１、検査装置４１２、検査装置４２１、および検査装置４２２は、充放電機能を備える。検査装置４１１、検査装置４１２、検査装置４２１、および検査装置４２２は、自装置にて充電を行う蓄電池モジュールに対して、充電時にＳＯＣ－ＯＣＶ特性を測定する。 Inspection device 411, inspection device 412, inspection device 421, and inspection device 422 have a charge/discharge function. Inspection device 411, inspection device 412, inspection device 421, and inspection device 422 measure the SOC-OCV characteristics of the storage battery module that is charged by the device itself during charging.

　例えば、検査装置４１１は、電池使用装置５１１の蓄電池モジュールを充電する場合に、電池使用装置５１１の蓄電池モジュールのＳＯＣ－ＯＣＶ特性を測定する。同様に、検査装置４１２、４２１、４２２のそれぞれは、電池使用装置５１２、５２１、５２２の蓄電池モジュールを充電する場合に、電池使用装置５１２、５２１、５２２の蓄電池モジュールのＳＯＣ－ＯＣＶ特性をそれぞれに測定する。 For example, when the inspection device 411 charges the storage battery module of the battery-powered device 511, it measures the SOC-OCV characteristics of the storage battery module of the battery-powered device 511. Similarly, when the inspection devices 412, 421, and 422 charge the storage battery modules of the battery-powered devices 512, 521, and 522, they each measure the SOC-OCV characteristics of the storage battery modules of the battery-powered devices 512, 521, and 522.

　また、検査装置４１１、検査装置４１２、検査装置４２１、および検査装置４２２は、自装置で充電した蓄電池モジュールのバッテリマネジメントシステム情報（ＢＭＳ情報）を、蓄電池モジュールから取得する。バッテリマネジメントシステム情報は、例えば、蓄電池モジュールの充電回数、使用日数、放置日数を含む。この際、検査装置４１１、検査装置４１２、検査装置４２１、および検査装置４２２は、自装置で充電した蓄電池モジュールの製造番号、および、蓄電池モジュールに用いられている電池セルの品番、製造番号を取得する。 In addition, inspection devices 411, 412, 421, and 422 acquire battery management system information (BMS information) of the storage battery module charged by their own devices from the storage battery module. The battery management system information includes, for example, the number of times the storage battery module has been charged, the number of days it has been used, and the number of days it has been left unused. At this time, inspection devices 411, 412, 421, and 422 acquire the serial number of the storage battery module charged by their own devices, and the product number and serial number of the battery cells used in the storage battery module.

　検査装置４１１および検査装置４１２は、自装置で取得したＳＯＣ－ＯＣＶ特性およびＢＭＳ情報を使用状態の検査結果として、稼働実績管理ＤＢ３１に送信する。 　Inspection device 411 and inspection device 412 transmit the SOC-OCV characteristics and BMS information acquired by their own devices to operation history management DB 31 as the inspection results of the usage state.

　稼働実績管理ＤＢ３１は、検査装置４１１および検査装置４１２から受信した蓄電池モジュール毎の使用状態の検査結果を蓄積する。この際、検査結果が蓄積されている蓄電池モジュールの製造番号と、この蓄電池モジュールに使用されている電池セルの品番および製造番号とは紐付けされている。 The operation history management DB31 accumulates the inspection results of the usage status of each storage battery module received from the inspection device 411 and the inspection device 412. At this time, the serial number of the storage battery module for which the inspection results are accumulated is linked to the product number and serial number of the battery cells used in this storage battery module.

　検査装置４２１、および検査装置４２２は、自装置で取得したＳＯＣ－ＯＣＶ特性およびＢＭＳ情報を使用状態の検査結果として、稼働実績管理ＤＢ３２に送信する。稼働実績管理ＤＢ３２は、検査装置４２１および検査装置４２２から受信した蓄電池モジュール毎の使用状態の検査結果を蓄積する。この際、検査結果が蓄積されている蓄電池モジュールの製造番号と、この蓄電池モジュールに使用されている電池セルの製造番号とは、紐付けされて、検査結果に含んだ状態で蓄積される。 Inspection devices 421 and 422 transmit the SOC-OCV characteristics and BMS information acquired by their own devices to operation history management DB 32 as inspection results for the usage state. Operation history management DB 32 accumulates the inspection results for the usage state of each storage battery module received from inspection devices 421 and 422. At this time, the serial number of the storage battery module for which the inspection results are accumulated is linked to the serial numbers of the battery cells used in this storage battery module, and is accumulated as part of the inspection results.

　製造品質管理ＤＢ６０は、電池セルの製造時における品質情報を蓄積する。具体的には、製造品質管理ＤＢ６０は、電池工場７１、７２、７３で製造された電池セルの製造番号およびこの電池セルを含む製造ロット番号を品質情報として蓄積する。 The manufacturing quality control DB 60 stores quality information on the manufacturing of battery cells. Specifically, the manufacturing quality control DB 60 stores the serial numbers of the battery cells manufactured in the battery factories 71, 72, and 73 and the manufacturing lot numbers that include these battery cells as quality information.

　また、電池工場７１、７２、７３において電池セルの製造時において不具合が発生した場合に、製造品質管理ＤＢ６０は、この不具合が生じた電池セルの製造番号およびこの電池セルを含む製造ロット番号を品質情報に追加して蓄積する。 In addition, if a defect occurs during the manufacture of a battery cell at battery factories 71, 72, and 73, manufacturing quality control DB 60 adds the manufacturing number of the battery cell with the defect and the manufacturing lot number that includes this battery cell to the quality information and stores them.

　（不具合判定後の各種情報の流れ）
　ユーザが電池使用装置の蓄電池モジュールの不具合を感じて、不具合の判定対象の蓄電池モジュールを販売店に持ち込む。この販売店に備えられた検査装置は、上述のように、不具合の判定対象の蓄電池モジュールのＳＯＣ－ＯＣＶ特性を測定し、この蓄電池モジュールのＢＭＳ情報を取得して、これらを含む検査結果を生成する。検査装置は、検査結果を稼働実績管理ＤＢに送信し、稼働実績管理ＤＢは、受信した検査結果を、中央管理装置２０に送信する。 (Flow of various information after defect determination)
A user feels that there is a problem with a storage battery module of a battery-powered device and brings the storage battery module to be judged for the problem to a dealer. As described above, an inspection device installed at the dealer measures the SOC-OCV characteristics of the storage battery module to be judged for the problem, acquires BMS information of the storage battery module, and generates an inspection result including these. The inspection device transmits the inspection result to an operation history management DB, and the operation history management DB transmits the received inspection result to the central management device 20.

　図３は、蓄電池モジュールの不具合判定後の各種情報の流れの一例を示す図である。 Figure 3 shows an example of the flow of various information after a malfunction of a storage battery module is determined.

　中央管理装置２０は、受信した検査結果におけるＳＯＣ－ＯＣＶ特性から、不具合の判定対象の蓄電池モジュール（電池セル）の劣化度を解析する。 The central management unit 20 analyzes the degree of deterioration of the storage battery module (battery cell) that is being judged to be defective based on the SOC-OCV characteristics in the received inspection results.

　また、中央管理装置２０は、不具合の判定対象の蓄電池モジュールのＢＭＳ情報を取得する。また、中央管理装置２０は、検査結果に含まれた紐付け情報に基づいて、不具合の判定対象の蓄電池モジュールに使用された電池セルの製造ロット番号を取得する。 The central management unit 20 also acquires the BMS information of the storage battery module that is being judged to have a malfunction. The central management unit 20 also acquires the manufacturing lot number of the battery cell used in the storage battery module that is being judged to have a malfunction, based on the linking information included in the inspection results.

　中央管理装置２０は、劣化度の解析結果に基づいて、不具合の判定対象の蓄電池モジュールが、製造時の不具合によるものか、または、使用による電池セルの劣化によるものかを判定する。この際、中央管理装置２０は、ＢＭＳ情報を参照する。 The central management unit 20 determines whether the storage battery module being judged to be defective is due to a manufacturing defect or deterioration of the battery cells due to use, based on the results of the deterioration level analysis. At this time, the central management unit 20 refers to the BMS information.

　具体的には、中央管理装置２０は、劣化度とＢＭＳ情報に基づいて、充電回数が許容回数を超えたことによる劣化、または、長時間充放電させずに放置等したことによる過放電による劣化であれば、判定対象の蓄電池モジュールについて、使用状態による電池セルの劣化であると判定する。 Specifically, based on the deterioration level and BMS information, if deterioration is due to the number of times charged exceeding the allowable number of times, or deterioration is due to over-discharging caused by leaving the battery module for an extended period of time without charging or discharging, the central management unit 20 determines that deterioration of the battery cells of the storage battery module being evaluated is due to usage conditions.

　一方、中央管理装置２０は、上述の判定結果を得られない場合は、製造時の不具合の可能性があると判定する。 On the other hand, if the central management unit 20 does not obtain the above-mentioned judgment result, it determines that there is a possibility of a manufacturing defect.

　中央管理装置２０は、製造時の不具合の可能性があると判定すると、電池セルの製造ロット番号を用いて、製造時の不具合があるか否かを製造品質管理ＤＢ６０に問合せする（不具合情報の問合せ）。 If the central management unit 20 determines that there is a possibility of a manufacturing defect, it uses the manufacturing lot number of the battery cell to inquire of the manufacturing quality control DB 60 whether or not there is a manufacturing defect (inquiry of defect information).

　製造品質管理ＤＢ６０は、自装置が蓄積する品質情報に基づいて、中央管理装置２０から問合せを受けた製造ロット番号において不具合が発生しているか否かを検出する。製造品質管理ＤＢ６０は、不具合の有無の検出結果を中央管理装置２０に回答する。 The manufacturing quality control DB 60 detects whether or not a defect has occurred in the manufacturing lot number inquired about by the central management unit 20 based on the quality information accumulated by the device itself. The manufacturing quality control DB 60 responds to the central management unit 20 with the detection result of the presence or absence of a defect.

　中央管理装置２０は、回答を受けた不具合の有無の検出結果に基づいて、製品メーカ側に不具合情報を通知する。また、中央管理装置２０は、劣化度を解析した蓄電池モジュールの充放電（ＳＯＣ－ＯＣＶ特性の測定）を行った検査装置に、劣化度の解析結果を通知する。 The central management unit 20 notifies the product manufacturer of the defect information based on the received response on the presence or absence of a defect. The central management unit 20 also notifies the deterioration analysis result to the inspection device that performed the charging and discharging (measurement of SOC-OCV characteristics) of the storage battery module whose deterioration level was analyzed.

　（Ａ）　使用状態による電池セルの劣化の場合
　図４は、使用状態による電池セルの劣化の場合の各種情報の流れの一例を示す図である。 (A) Case where Battery Cell Deterioration Occurs Due to Usage Condition FIG. 4 is a diagram showing an example of the flow of various types of information when a battery cell has deteriorated due to usage condition.

　中央管理装置２０は、不具合の判定対象の蓄電池モジュールの電池セルが使用状態による劣化を生じていると判定した場合、この判定結果および劣化度の解析結果を稼働実績管理ＤＢに通知（送信）する。稼働実績管理ＤＢは、受信した判定結果を蓄積する。稼働実績管理ＤＢは、判定結果および劣化度の解析結果を、劣化度を解析した蓄電池モジュールの充放電を行った検査装置に通知（送信）する。 If the central management unit 20 determines that the battery cells of the storage battery module being judged for malfunction have deteriorated due to usage, it notifies (sends) this judgment result and the analysis result of the deterioration level to the operation history management DB. The operation history management DB stores the received judgment results. The operation history management DB notifies (sends) the judgment result and the analysis result of the deterioration level to the inspection device that charged and discharged the storage battery module whose deterioration level was analyzed.

　検査装置は、例えば、表示装置を備えており、判定結果および劣化度の解析結果を受信した検査装置は、受信した判定結果および劣化度の解析結果を表示する。これにより、販売店の店員およびユーザは、不具合の判定結果および蓄電池モジュール（電池セル）の劣化度を容易に把握できる。 The inspection device, for example, is equipped with a display device, and upon receiving the judgment result and the analysis result of the deterioration level, the inspection device displays the received judgment result and the analysis result of the deterioration level. This allows the salesperson at the dealership and the user to easily understand the defect judgment result and the deterioration level of the storage battery module (battery cell).

　例えば、図４に示すように、電池使用装置５１１の蓄電池モジュールが販売店１１に持ち込まれ、検査装置４１１は、電池使用装置５１１の蓄電池モジュールのＳＯＣ－ＯＣＶ特性の測定、および、ＢＭＳ情報の取得を行う。中央管理装置２０は、これらの情報に基づいて、劣化度の解析を行うとともに、ＢＭＳ情報を参照して、使用状態による電池セルの劣化であると判定する。 For example, as shown in FIG. 4, the storage battery module of the battery-powered device 511 is brought to the dealer 11, and the inspection device 411 measures the SOC-OCV characteristics of the storage battery module of the battery-powered device 511 and acquires the BMS information. The central management device 20 analyzes the degree of deterioration based on this information, and refers to the BMS information to determine that the deterioration of the battery cells is due to the usage conditions.

　中央管理装置２０は、判定結果および劣化度の解析結果を稼働実績管理ＤＢ３１に通知（送信）する。稼働実績管理ＤＢ３１は、判定結果および劣化度の解析結果を検査装置４１１に通知（送信）する。検査装置４１１は、判定結果および劣化度の解析結果を表示する。 The central management device 20 notifies (sends) the judgment result and the analysis result of the deterioration level to the operation history management DB 31. The operation history management DB 31 notifies (sends) the judgment result and the analysis result of the deterioration level to the inspection device 411. The inspection device 411 displays the judgment result and the analysis result of the deterioration level.

　（Ｂ）　製造時の不具合の可能性がある場合
　図５は、製造時の不具合による電池セル故障の場合の各種情報の流れの一例を示す図である。 (B) When there is a possibility of a manufacturing defect FIG. 5 is a diagram showing an example of the flow of various types of information when a battery cell malfunctions due to a manufacturing defect.

　中央管理装置２０は、製造品質管理ＤＢ６０への問合せと回答によって、不具合の判定対象の蓄電池モジュールの電池セルが製造時の不具合によって故障したものと判定した場合、この判定結果（不具合情報）を稼働実績管理ＤＢに通知（送信）する。この際、中央管理装置２０は、故障が発生した電池セルと同じ製造ロットの電池の出荷先（製品メーカ）を、製造品質管理ＤＢ６０から取得する。中央管理装置２０は、取得した出荷先の稼働実績管理ＤＢにも、稼働実績管理ＤＢに通知（送信）する。 If the central management unit 20 determines, based on an inquiry to and response from the manufacturing quality control DB 60, that a battery cell of the storage battery module being judged to be defective has failed due to a defect during manufacturing, it notifies (sends) this judgment result (defect information) to the operation history management DB. At this time, the central management unit 20 obtains from the manufacturing quality control DB 60 the shipping destination (product manufacturer) of batteries from the same manufacturing lot as the defective battery cell. The central management unit 20 also notifies (sends) the operation history management DB of the obtained shipping destination.

　不具合情報を受信した稼働実績管理ＤＢは、判定結果（不具合情報）を蓄積する。稼働実績管理ＤＢは、判定結果（不具合情報）を、それぞれがデータ通信可能な検査装置に通知（送信）する。 The operation history management DB that receives the defect information stores the judgment result (defect information). The operation history management DB notifies (sends) the judgment result (defect information) to each of the inspection devices with which data communication is possible.

　検査装置は、例えば、表示装置を備えており、判定結果（不具合情報）を受信した検査装置は、判定結果（不具合情報）を表示する。これにより、各販売店の店員およびユーザは、判定結果（不具合情報）を容易に把握できる。 The inspection device is equipped with, for example, a display device, and upon receiving the judgment result (defect information), the inspection device displays the judgment result (defect information). This allows sales staff at each store and users to easily understand the judgment result (defect information).

　例えば、図５に示すように、電池使用装置５１１の蓄電池モジュールが販売店１１に持ち込まれ、検査装置４１１は、電池使用装置５１１の蓄電池モジュールのＳＯＣ－ＯＣＶ特性の測定、および、ＢＭＳ情報の取得を行う。中央管理装置２０は、これらの情報に基づいて、劣化度の解析を行うとともに、ＢＭＳ情報を参照して、製造時の不具合の可能性があることを判定する。中央管理装置２０は、製造品質管理ＤＢ６０に問合せに基づいて、製造時の不具合による電池セルの故障であるか否かを判定する。 For example, as shown in FIG. 5, the storage battery module of the battery-powered device 511 is brought into the retail store 11, and the inspection device 411 measures the SOC-OCV characteristics of the storage battery module of the battery-powered device 511 and acquires the BMS information. The central management unit 20 analyzes the degree of deterioration based on this information, and refers to the BMS information to determine whether there is a possibility of a manufacturing defect. The central management unit 20 queries the manufacturing quality management DB 60 to determine whether the battery cell has failed due to a manufacturing defect.

　中央管理装置２０は、製造時の不具合による電池セルの故障であれば、この判定結果（不具合情報）を稼働実績管理ＤＢ３１に通知（送信）する。さらに、中央管理装置２０は、この故障した電池セルと同じ製造ロット番号の電池セルが、製品メーカ２に出荷されていることを検出すると、この判定結果（不具合情報）を稼働実績管理ＤＢ３２に通知（送信）する。 If the failure of the battery cell is due to a defect during manufacturing, the central management unit 20 notifies (sends) this determination result (defect information) to the operation history management DB 31. Furthermore, if the central management unit 20 detects that a battery cell with the same manufacturing lot number as the failed battery cell has been shipped to the product manufacturer 2, it notifies (sends) this determination result (defect information) to the operation history management DB 32.

　稼働実績管理ＤＢ３１は、判定結果（不具合情報）を自装置に蓄積するとともに、検査装置４１１に通知（送信）する。検査装置４１１は、判定結果（不具合情報）を表示する。なお、稼働実績管理ＤＢ３１は、判定結果（不具合情報）を検査装置４１２に通知（送信）してもよく、通知（送信）しなくてもよい。 The operation history management DB 31 accumulates the judgment result (defect information) in its own device and notifies (sends) it to the inspection device 411. The inspection device 411 displays the judgment result (defect information). Note that the operation history management DB 31 may or may not notify (send) the judgment result (defect information) to the inspection device 412.

　稼働実績管理ＤＢ３２は、判定結果（不具合情報）を自装置に蓄積する。稼働実績管理ＤＢ３２は、判定結果（不具合情報）を検査装置４２１および検査装置４２２に通知（送信）してもよく、通知（送信）しなくてもよい。 Operation history management DB32 accumulates the judgment results (defect information) in its own device. Operation history management DB32 may or may not notify (send) the judgment results (defect information) to inspection device 421 and inspection device 422.

　さらに、中央管理装置２０は、判定結果（不具合情報）のうち、製造品質に関連する内容（どのような不具合が生じたか等）を、製造品質管理ＤＢ６０に通知（送信）する。製造品質管理ＤＢ６０は、受信した製造品質に関連する内容を、製造ロット番号に紐付けして蓄積する。 Furthermore, the central management unit 20 notifies (sends) the manufacturing quality control DB 60 of the contents related to manufacturing quality (such as what kind of defect occurred) from among the judgment results (defect information). The manufacturing quality control DB 60 stores the received contents related to manufacturing quality by linking them to the manufacturing lot number.

　例えば、電池工場７１、７２、７３のそれぞれにおいて、１ロットで３００本の電池セルが製造されている。電池工場７１で製造された３００本が製造ロット番号ＬＯＴ１であり、電池工場７１で製造された３００本が製造ロット番号ＬＯＴ２であり、電池工場７３で製造された３００本が製造ロット番号ＬＯＴ３である。さらに、製造ロット番号ＬＯＴ１の３００本の電池セルは、製造番号１－３００が付与されており、製造ロット番号ＬＯＴ２の３００本の電池セルは、製造番号３０１－６００が付与されており、製造ロット番号ＬＯＴ３の３００本の電池セルは、製造番号６０１－９００が付与されている。 For example, 300 battery cells are manufactured in one lot at each of battery factories 71, 72, and 73. The 300 cells manufactured at battery factory 71 have manufacturing lot number LOT1, the 300 cells manufactured at battery factory 71 have manufacturing lot number LOT2, and the 300 cells manufactured at battery factory 73 have manufacturing lot number LOT3. Furthermore, the 300 battery cells of manufacturing lot number LOT1 are assigned serial numbers 1-300, the 300 battery cells of manufacturing lot number LOT2 are assigned serial numbers 301-600, and the 300 battery cells of manufacturing lot number LOT3 are assigned serial numbers 601-900.

　各製造ロットのそれぞれ１００本ずつが製品メーカ１（例えば、電動アシスト自転車メーカや自動車メーカ）、製品メーカ２（例えば、自動車メーカ）、および、製品メーカ３（例えば、電動工具メーカ）に出荷されている。なお、上記説明では、製品メーカ３は図示を省略しているが、以下の説明上、製品メーカ３が存在するものとする。 100 pieces from each production lot are shipped to product manufacturer 1 (e.g., an electrically assisted bicycle manufacturer or an automobile manufacturer), product manufacturer 2 (e.g., an automobile manufacturer), and product manufacturer 3 (e.g., a power tool manufacturer). Note that in the above explanation, product manufacturer 3 is not shown, but for the purposes of the following explanation, it is assumed that product manufacturer 3 exists.

　具体的には、製造ロット番号ＬＯＴ１の製造番号１－１００、製造ロット番号ＬＯＴ２の製造番号３０１－４００、製造ロット番号ＬＯＴ３の製造番号６０１－７００が製品メーカ１に出荷されている。製造ロット番号ＬＯＴ１の製造番号１０１－２００、製造ロット番号ＬＯＴ２の製造番号４０１－５００、製造ロット番号ＬＯＴ３の製造番号７０１－８００が製品メーカ２に出荷されている。製造ロット番号ＬＯＴ１の製造番号２０１－３００、製造ロット番号ＬＯＴ２の製造番号５０１－６００、製造ロット番号ＬＯＴ３の製造番号８０１－９００が製品メーカ３に出荷されている。 Specifically, serial numbers 1-100 of production lot number LOT1, serial numbers 301-400 of production lot number LOT2, and serial numbers 601-700 of production lot number LOT3 have been shipped to product manufacturer 1. Serial numbers 101-200 of production lot number LOT1, serial numbers 401-500 of production lot number LOT2, and serial numbers 701-800 of production lot number LOT3 have been shipped to product manufacturer 2. Serial numbers 201-300 of production lot number LOT1, serial numbers 501-600 of production lot number LOT2, and serial numbers 801-900 of production lot number LOT3 have been shipped to product manufacturer 3.

　ここで、製品メーカ１に使われている電池セル（製造番号５０）が検査装置４１１にかけられて、ＳＯＣ－ＯＣＶ特性を取得して劣化度解析を行った結果、劣化要因が製造時に関わるものであると推定された場合、中央管理装置２０は、その製造番号の電池セルと同ロットの電池セル（製造番号１－３００）のうち、製品メーカ１に出荷されている他の製造番号１－４９、５１－１００の電池セルに類似の不具合情報がないか、製品メーカ２に出荷されている製造番号１０１－２００の電池セルに類似の不具合情報がないか、製品メーカ３に出荷されている製造番号２０１－３００の電池セルに類似の不具合情報がないかを、製造品質管理ＤＢ６０に照会する。中央管理装置２０は、もし製品メーカ２または製品メーカ３に出荷している電池セルに類似の不具合情報があった場合は、その情報を通知するとともに、製造品質管理ＤＢ６０に製造番号５０の電池セルの不具合情報を通知する。 Here, if the battery cell (serial number 50) used by product manufacturer 1 is subjected to inspection device 411, and the SOC-OCV characteristics are acquired and a degradation analysis is performed, and as a result it is estimated that the degradation factor is related to manufacturing, the central management unit 20 queries the manufacturing quality control DB 60 to check whether there is similar defect information for other battery cells with serial numbers 1-49 and 51-100 shipped to product manufacturer 1 among the battery cells (serial numbers 1-300) in the same lot as the battery cell with that serial number, whether there is similar defect information for battery cells with serial numbers 101-200 shipped to product manufacturer 2, or whether there is similar defect information for battery cells with serial numbers 201-300 shipped to product manufacturer 3. If there is similar defect information for battery cells shipped to product manufacturer 2 or product manufacturer 3, the central management unit 20 notifies the product quality control DB 60 of that information and also notifies the manufacturing quality control DB 60 of the defect information for the battery cell with serial number 50.

　以上のように、蓄電池管理システム１０は、蓄電池の不具合をユーザから受けたときに、劣化が進んでいるだけなのか、製造時要因を含む不具合が発生しているのか判定して通知できる。 As described above, when a user reports a malfunction of a storage battery, the storage battery management system 10 can determine whether the battery is simply deteriorating or whether a malfunction has occurred that may be due to manufacturing factors, and notify the user.

　（蓄電池管理方法）
　図６は、第１の実施形態に係る蓄電池管理方法のシステムフローの一例を示すフローチャート群である。なお、図６のフローチャート群に示す各処理の具体的な内容は、上述の構成の説明で行っている。したがって、以下の蓄電池管理方法については、必要な箇所を除いて具体的な内容の説明を省略する。 (Battery management method)
6 is a set of flowcharts showing an example of a system flow of the storage battery management method according to the first embodiment. Note that the specific contents of each process shown in the set of flowcharts in FIG. 6 are described in the above-mentioned configuration. Therefore, the specific contents of the storage battery management method below will not be described except where necessary.

　電池メーカの製造品質管理ＤＢ６０は、自社で製造した電池セルの製造番号と製造ロット番号を取得し、中央管理装置２０に送信する（Ｓ６１）。 The battery manufacturer's manufacturing quality control DB 60 acquires the manufacturing number and manufacturing lot number of the battery cells manufactured by the manufacturer and transmits them to the central management unit 20 (S61).

　検査装置（検査装置４１１、４１２、４２１、４２２におけるこれから充電を行うとする検査装置）は、これから充電を行おうとする蓄電池モジュールに用いられる電池セルの製造番号およびＢＭＳ情報を取得する（Ｓ１１）。検査装置は、蓄電池モジュール（電池セル）のＢＭＳを、製造番号とともに中央管理装置２０に送信する（Ｓ１２）。 The inspection device (the inspection device that will perform charging among inspection devices 411, 412, 421, and 422) acquires the serial number and BMS information of the battery cell used in the storage battery module that will perform charging (S11). The inspection device transmits the BMS of the storage battery module (battery cell) together with the serial number to the central management device 20 (S12).

　検査装置は、蓄電池モジュールの充電とＳＯＣ－ＯＣＶ特性の測定を開始する（Ｓ１３）。検査装置は、ＳＯＣーＯＣＶ特性の測定が完了すると（Ｓ１４：ＹＥＳ）、ＳＯＣ－ＯＣＶ特性を中央管理装置２０に送信する。 The inspection device starts charging the storage battery module and measuring the SOC-OCV characteristics (S13). When the measurement of the SOC-OCV characteristics is completed (S14: YES), the inspection device transmits the SOC-OCV characteristics to the central management unit 20.

　中央管理装置２０は、ＳＯＣ－ＯＣＶ特性から蓄電池モジュール（電池セル）の劣化度を解析する（Ｓ２１）。 The central management unit 20 analyzes the degree of deterioration of the storage battery module (battery cell) from the SOC-OCV characteristics (S21).

　中央管理装置２０は、劣化度の解析結果から、劣化要因が製造段階の不具合によるものではないと判定すると（Ｓ２２：ＮＯ）、劣化度の解析結果を検査装置に通知する（Ｓ２３）。 If the central management unit 20 determines from the results of the deterioration level analysis that the cause of the deterioration is not due to a defect in the manufacturing stage (S22: NO), it notifies the inspection device of the results of the deterioration level analysis (S23).

　中央管理装置２０は、劣化度の解析結果から、劣化要因が製造段階の不具合によるものであると判定すると（Ｓ２２：ＹＥＳ）、劣化度の解析を行った電池セルの製造番号、ロット番号から、当該電池セルを製造した電池メーカ（製造品質管理ＤＢ６０）を識別し、この製造品質管理ＤＢ６０に製造ロット番号と不具合情報を問い合わせる（Ｓ２４）。 If the central management unit 20 determines from the degradation analysis results that the degradation was caused by a defect during the manufacturing stage (S22: YES), it identifies the battery manufacturer (manufacturing quality control DB 60) that manufactured the battery cell from the manufacturing number and lot number of the battery cell for which degradation analysis was performed, and queries this manufacturing quality control DB 60 for the manufacturing lot number and defect information (S24).

　製造品質管理ＤＢ６０は、製造ロット番号と不具合情報の問合せを受信する（Ｓ６２）。製造品質管理ＤＢ６０は、同製造ロット番号で他の製品メーカに出荷した電池セルに同様の不具合が有るかを確認する。 The manufacturing quality control DB 60 receives the inquiry about the manufacturing lot number and defect information (S62). The manufacturing quality control DB 60 checks whether the same defect exists in battery cells shipped to other product manufacturers with the same manufacturing lot number.

　製造品質管理ＤＢ６０は、不具合があれば（Ｓ６３：ＹＥＳ）、中央管理装置２０に不具合有り情報を返答する（Ｓ６４）。製造品質管理ＤＢ６０は、不具合がなければ（Ｓ６３：ＮＯ）、中央管理装置２０に不具合無し情報を返答する（Ｓ６５）。 If there is a defect (S63: YES), the manufacturing quality control DB 60 returns information indicating that there is a defect to the central management unit 20 (S64). If there is no defect (S63: NO), the manufacturing quality control DB 60 returns information indicating that there is no defect to the central management unit 20 (S65).

　中央管理装置２０は、製造品質管理ＤＢ６０（電池メーカ）からの返答を受信する（Ｓ２５）。中央管理装置２０は、不具合が有れば（Ｓ２６：ＹＥＳ）、対象の電池セル含む製造ロット番号の電池セルを使用する（出荷した）全ての製品メーカへ不具合情報を通知する（Ｓ２７）。 The central management unit 20 receives a response from the manufacturing quality control DB 60 (battery manufacturer) (S25). If a defect is found (S26: YES), the central management unit 20 notifies all product manufacturers that use (ship) battery cells with the same manufacturing lot number as the target battery cell of the defect information (S27).

中央管理装置２０は、不具合が無ければ（Ｓ２６：ＮＯ）、対象の電池セルを使用する（出荷した）製品メーカへ不具合情報を通知する（Ｓ２８）。 If there is no defect (S26: NO), the central management unit 20 notifies the product manufacturer that uses (ships) the target battery cell of the defect information (S28).

　［第２の実施形態］
　本発明の第２の実施形態に係る蓄電池管理システムについて、図を参照して説明する。図７は、第２の実施形態に係る蓄電池管理システムの構成例および情報の流れを示す図である。 Second Embodiment
A storage battery management system according to a second embodiment of the present invention will be described with reference to Fig. 7. Fig. 7 is a diagram showing an example of the configuration and information flow of the storage battery management system according to the second embodiment.

　図７に示すように、第２の実施形態に係る蓄電池管理システム１０Ａは、第１の実施形態に係る蓄電池管理システム１０に対して、劣化度の解析結果の通知方法が異なる。蓄電池管理システム１０Ａの他の構成および処理は、蓄電池管理システム１０と同様であり、同様の箇所の説明は省略する。 As shown in FIG. 7, the battery management system 10A according to the second embodiment differs from the battery management system 10 according to the first embodiment in the method of notifying the results of the analysis of the deterioration level. The other configurations and processes of the battery management system 10A are similar to those of the battery management system 10, and a description of similar parts will be omitted.

　中央管理装置２０は、蓄電池モジュール（電池セル）の劣化度を解析し、解析結果を生成すると、劣化度を解析した蓄電池モジュール（電池セル）を充電した検査装置に、解析結果を直接通知する。 The central management unit 20 analyzes the degree of deterioration of the storage battery module (battery cell) and generates the analysis results, and then notifies the analysis results directly to the inspection device that charged the storage battery module (battery cell) whose deterioration level was analyzed.

　このような構成によって、蓄電池管理システム１０Ａは、蓄電池管理システム１０と同様の作用効果を奏することができる。 With this configuration, the battery management system 10A can achieve the same effects as the battery management system 10.

　上述の説明では、稼働実績管理ＤＢが２台で、検査装置が４台の場合を示すが、これらの台数はここに示す台数の限りではない。例えば、蓄電池モジュールを利用する製品メーカが３社以上である場合には、メーカ数に応じた台数の稼働実績管理ＤＢが含まれる。また、１つの製品メーカに属する販売店の店数が３店以上である場合には、店数に応じた台数の検査装置が含まれる。 The above explanation shows a case where there are two operation history management DBs and four inspection devices, but these numbers are not limited to the numbers shown here. For example, if there are three or more product manufacturers that use storage battery modules, the number of operation history management DBs included corresponds to the number of manufacturers. Also, if there are three or more retail stores belonging to one product manufacturer, the number of inspection devices included corresponds to the number of stores.
