Description

本発明は、組電池に関する。 The present invention relates to an assembled battery.

従来、複数の二次電池モジュールを組み合わせてなる組電池が様々な用途に用いられている。特許文献１には、交換可能に構成された複数の二次電池モジュールを備えた組電池において、基準以上に劣化した二次電池モジュールを、予めメモリー効果を付与して劣化させた二次電池モジュールと交換することにより、組電池に備えられた複数の二次電池モジュール間での劣化度などの特性のバラツキを低減して故障の誤判定を回避することが開示されている。 Conventionally, an assembled battery formed by combining a plurality of secondary battery modules has been used for various purposes. In Patent Document 1, in an assembled battery including a plurality of replaceable secondary battery modules, the secondary battery module deteriorated more than the standard is given a memory effect in advance and deteriorated. It is disclosed that by replacing the battery with a battery, the variation in characteristics such as the degree of deterioration among a plurality of secondary battery modules provided in the assembled battery is reduced to avoid erroneous determination of failure.

特開２００３－３４６９０９号公報Japanese Patent Application Laid-Open No. 2003-346909

しかしながら、特許文献１に開示の構成では、交換に際して劣化度のバラツキが低減されるように二次電池モジュールを組み合わせている。そのため、組電池全体として性能を高く維持させようとすると、劣化度が比較的高い二次電池モジュールは利用されにくくなり、二次電池モジュールの再利用率の低下を招く。 However, in the configuration disclosed in Patent Document 1, the secondary battery module is combined so as to reduce the variation in the degree of deterioration at the time of replacement. Therefore, if an attempt is made to maintain high performance of the assembled battery as a whole, it becomes difficult to use the secondary battery module having a relatively high degree of deterioration, which leads to a decrease in the reuse rate of the secondary battery module.

本発明は、かかる背景に鑑みてなされたもので、組電池としての性能を高く維持しつつ、二次電池モジュールの再利用の促進に寄与する組電池を提供しようとするものである。 The present invention has been made in view of this background, and an object of the present invention is to provide an assembled battery that contributes to promotion of reuse of a secondary battery module while maintaining high performance as an assembled battery.

本発明の一態様は、複数の二次電池モジュール（１０、１１、１２、１３、１４、１５、１６、１７）と、該二次電池モジュールが配設される複数の配設部（２０、２１、２２、２３、２４、２５、２６、２７）とを有する組電池（１）であって、
上記複数の配設部を、それぞれの配設部に配設された上記二次電池モジュールの劣化させやすさを順位付けした劣化促進順位が、上記複数の配設部における劣化促進順位の中央値よりも小さい上位のグループである劣化促進上位グループ（２０１）と、上記劣化促進順位の中央値以上の下位のグループである劣化促進下位グループ（２０２）とに分けたとき、上記複数の二次電池モジュールのうち最も劣化度の小さい二次電池モジュール（１４）は、上記劣化促進上位グループに属する上記配設部（２３、２４、２５）に配設されており、
上記複数の二次電池モジュールを、上記複数の二次電池モジュールにおける劣化度の中央値よりも小さい劣化度小グループ（１０１）と、上記劣化度の中央値以上である劣化度大グループ（１０２）とに分けたとき、上記劣化度小グループに属する上記二次電池モジュール（１３、１４、１５）は、上記劣化促進上位グループに属する上記配設部（２３、２４、２５）に配設されており、
上記複数の二次電池モジュールは、上記劣化度の大きさに基づいて４以上の順位数で順位付けしたとき、互いに隣り合う上記二次電池モジュールにおける上記劣化度の順位の差は２以下であり、
互いに隣り合う上記二次電池モジュールにおける上記劣化度の差を検出して故障判定を行うことができるように構成されている、組電池にある。 One aspect of the present invention is a plurality of secondary battery modules (10, 11, 12, 13, 14, 15, 16, 17) and a plurality of disposition portions (20,) in which the secondary battery modules are disposed. 21, 22, 23, 24, 25, 26, 27) and the assembled battery (1).
The deterioration promotion order in which the deterioration susceptibility of the secondary battery module arranged in each of the plurality of arrangement portions is ranked is the median value of the deterioration promotion order in the plurality of arrangement portions. When divided into a deterioration promotion upper group (201), which is a smaller upper group, and a deterioration promotion lower group (202), which is a lower group equal to or higher than the median of the deterioration promotion order, the plurality of secondary batteries are described above. The secondary battery module (14) having the smallest degree of deterioration among the modules is arranged in the arrangement portion (23, 24, 25) belonging to the deterioration promotion upper group.
The plurality of secondary battery modules have a small deterioration degree group (101) smaller than the median deterioration degree of the plurality of secondary battery modules and a large deterioration degree group (102) having the median degree of deterioration or more. When divided into the above, the secondary battery modules (13, 14, 15) belonging to the deterioration degree small group are arranged in the arrangement portions (23, 24, 25) belonging to the deterioration promotion upper group. Ori,
When the plurality of secondary battery modules are ranked by the number of ranks of 4 or more based on the magnitude of the degree of deterioration, the difference in the rank of the degree of deterioration between the adjacent secondary battery modules is 2 or less. ,
The assembled battery is configured to detect the difference in the degree of deterioration of the secondary battery modules adjacent to each other and determine the failure .

上記組電池においては、劣化促進上位グループに属する配設部に配設された二次電池モジュールは劣化が進みやすい。そして、劣化促進上位グループに属する配設部に最も劣化度の小さい二次電池モジュールが配設されているため、当該配設部に劣化度の大きい他の二次電池モジュールが配設される場合に比べて、組電池全体としての性能を向上させることができる。そして、劣化度の比較的大きい二次電池モジュールを劣化促進下位グループに属する他の配設部に配設することができるため、結果として二次電池モジュールの再利用率向上に寄与することができる。 In the above-mentioned assembled battery, the secondary battery module arranged in the arrangement portion belonging to the deterioration promotion upper group tends to deteriorate. Further, since the secondary battery module having the lowest degree of deterioration is disposed in the disposition portion belonging to the deterioration promotion upper group, the case where another secondary battery module having a large degree of deterioration is disposed in the disposition portion. Compared with, the performance of the assembled battery as a whole can be improved. Further, since the secondary battery module having a relatively large degree of deterioration can be arranged in another arrangement portion belonging to the deterioration promotion lower group, it is possible to contribute to the improvement of the reuse rate of the secondary battery module as a result. ..

以上のごとく、本発明によれば、組電池としての性能を高く維持しつつ、二次電池モジュールの再利用の促進に寄与する組電池を提供することができる。 As described above, according to the present invention, it is possible to provide an assembled battery that contributes to the promotion of reuse of the secondary battery module while maintaining high performance as an assembled battery.

（実施形態１）
上記組電池の実施形態について、図１～図３を用いて説明する。
本実施形態の組電池１は、複数の二次電池モジュール１０と、二次電池モジュール１０が配設される複数の配設部２０とを有する。
そして、複数の配設部２０を、それぞれの配設部２０に配設された二次電池モジュール１０の劣化させやすさを順位付けした劣化促進順位が、複数の配設部２０における劣化促進順位の中央値よりも小さい上位のグループである劣化促進上位グループ２０１と、劣化促進順位の中央値以上の下位のグループである劣化促進下位グループ２０２とに分けたとき、複数の二次電池モジュール１０のうち最も劣化度の小さい二次電池モジュール１４は、劣化促進上位グループ２０１に属する配設部２４に配設されている。 (Embodiment 1)
The embodiment of the assembled battery will be described with reference to FIGS. 1 to 3.
The assembled battery 1 of the present embodiment has a plurality of secondary battery modules 10 and a plurality of disposition portions 20 in which the secondary battery modules 10 are disposed.
Then, the deterioration promotion order in which the deterioration susceptibility of the secondary battery modules 10 arranged in the respective arrangement portions 20 is ranked is the deterioration promotion order in the plurality of arrangement portions 20. When divided into a deterioration promotion upper group 201, which is a higher group smaller than the median value, and a deterioration promotion lower group 202, which is a lower group group equal to or higher than the median deterioration promotion order, the plurality of secondary battery modules 10 Among them, the secondary battery module 14 having the smallest degree of deterioration is arranged in the arrangement portion 24 belonging to the deterioration promotion upper group 201.

以下、本実施形態の組電池１について、詳述する。
本実施形態の組電池１は、二次電池モジュール１０が配設される配設部２０を複数備える。本実施形態では、図１に示すように、複数の配設部２０は、第１配設部２１、第２配設部２２、第３配設部２３、第４配設部２４、第５配設部２５、第６配設部２６、第７配設部２７の７つを含んでいる。各配設部２１～２７において、それぞれに配設された二次電池モジュール１０の劣化させやすさは均一ではない。そのため、各配設部２１～２７に対して二次電池モジュール１０の劣化させやすさを順位付けすることができる。そして、当該順位を配設部２１～２７における劣化促進順位とする。従って、劣化促進順位が“１”の場合、配設部２１～２７において二次電池モジュール１０を最も劣化させやすく、劣化促進順位が増えるほど、すなわち、順位が下位になるほど二次電池モジュール１０を劣化させにくくなる。劣化促進順位は、例えば、配設部２１～２７におけるそれぞれの温度上昇速度によって規定することができる。本実施形態では、二次電池モジュール１０は高温になると劣化が促進されやすいことに鑑みて、配設部２１～２７を通電時の温度上昇速度の高い順に順位付けし、最も順位の高いものを劣化促進順位“１”として以下順に“２、３、４…”と付与する。 Hereinafter, the assembled battery 1 of the present embodiment will be described in detail.
The assembled battery 1 of the present embodiment includes a plurality of arrangement portions 20 in which the secondary battery module 10 is arranged. In the present embodiment, as shown in FIG. 1, the plurality of arrangement portions 20 are the first arrangement portion 21, the second arrangement portion 22, the third arrangement portion 23, the fourth arrangement portion 24, and the fifth. It includes seven arrangement portions 25, a sixth arrangement portion 26, and a seventh arrangement portion 27. In each of the disposition portions 21 to 27, the easiness of deterioration of the secondary battery modules 10 disposed in each is not uniform. Therefore, it is possible to rank the ease of deterioration of the secondary battery module 10 with respect to each of the disposition portions 21 to 27. Then, the order is set as the deterioration promotion order in the arrangement portions 21 to 27. Therefore, when the deterioration promotion order is "1", the secondary battery module 10 is most likely to be deteriorated in the arrangement portions 21 to 27, and the secondary battery module 10 is generated as the deterioration promotion order increases, that is, as the order becomes lower. It becomes difficult to deteriorate. The deterioration promotion order can be defined by, for example, the respective temperature rise rates in the disposition portions 21 to 27. In the present embodiment, in view of the fact that the secondary battery module 10 tends to deteriorate when the temperature becomes high, the arrangement portions 21 to 27 are ranked in descending order of the temperature rise rate when energized, and the one having the highest rank is selected. As the deterioration promotion order "1", "2, 3, 4 ..." are given in the following order.

本実施形態では、配設部２１～２７は紙面横方向である並び方向Ｘに並んでいる。そして、配設部２１～２７における通電時の温度上昇速度は、並び方向Ｘの中央に位置する第４配設部２４が最も高く、第４配設部２４から離れるにつれて低くなっており、並び方向Ｘの両端に位置する第１配設部２１と第７配設部２７が最も低くなっている。図２のグラフでは、横軸が配設部２１～２７の並び方向Ｘに対応して、配設部２１～２７の位置を示している。そして、温度上昇速度に基づいて順位付けした劣化促進順位は、第４配設部２４が“１”で最も小さく、第３配設部２３及び第５配設部２５がそれぞれ“２”であり、第２配設部２２及び第６配設部２６がそれぞれ“３”であり、第１配設部２１及び第７配設部２７がそれぞれ“４”である。 In the present embodiment, the arrangement portions 21 to 27 are arranged in the arrangement direction X, which is the horizontal direction of the paper surface. The temperature rise rate at the time of energization in the arrangement portions 21 to 27 is highest in the fourth arrangement portion 24 located at the center of the arrangement direction X, and decreases as the distance from the fourth arrangement portion 24 increases. The first arrangement portion 21 and the seventh arrangement portion 27 located at both ends of the direction X are the lowest. In the graph of FIG. 2, the horizontal axis indicates the position of the arrangement portions 21 to 27 corresponding to the arrangement direction X of the arrangement portions 21 to 27. The deterioration promotion order ranked based on the temperature rise rate is "1" for the fourth arrangement portion 24, which is the smallest, and "2" for the third arrangement portion 23 and the fifth arrangement portion 25, respectively. , The second arrangement portion 22 and the sixth arrangement portion 26 are each "3", and the first arrangement portion 21 and the seventh arrangement portion 27 are "4", respectively.

そして、図２に示すように、配設部２１～２７は劣化促進順位が中央値よりも小さい上位のグループである劣化促進上位グループ２０１と、劣化促進順位が中央値以上である下位のグループである劣化促進下位グループ２０２とに分けることができる。劣化促進順位の中央値とは、劣化促進順位の各値を小さいものから順に並べたときの数値配列の中央に位置する値である。なお、数値配列のデータ件数が偶数の場合は、中央の２つの値の平均値を中央値とする。本実施形態では、劣化促進順位の値を小さい順に並べたときの数値配列は｛１、２、２、３、３、４、４｝であってその中央値は“３”である。従って、配設部２１～２７において、劣化促進上位グループ２０１は劣化促進順位が中央値よりも小さい上位の第３配設部２３、第４配設部２４及び第５配設部２５からなる。劣化促進下位グループ２０２は、劣化促進順位が中央値以上である下位の第１配設部２１、第２配設部２２、第６配設部２６及び第７配設部２７からなる。 Then, as shown in FIG. 2, the disposition portions 21 to 27 are divided into a deterioration promotion upper group 201, which is a higher group whose deterioration promotion order is smaller than the median, and a lower group whose deterioration promotion order is equal to or higher than the median. It can be divided into a certain deterioration promotion lower group 202. The median value of the deterioration promotion order is a value located in the center of the numerical array when each value of the deterioration promotion order is arranged in order from the smallest one. When the number of data items in the numerical array is even, the average value of the two values in the center is used as the median value. In the present embodiment, the numerical arrangement when the values of the deterioration promotion order are arranged in ascending order is {1, 2, 2, 3, 3, 4, 4}, and the median value thereof is "3". Therefore, in the disposition portions 21 to 27, the deterioration promotion upper group 201 is composed of a higher third disposition portion 23, a fourth disposition portion 24, and a fifth disposition portion 25 having a deterioration promotion order smaller than the median. The deterioration promotion lower group 202 is composed of a lower first arrangement portion 21, a second arrangement portion 22, a sixth arrangement portion 26, and a seventh arrangement portion 27 whose deterioration promotion order is equal to or higher than the median.

複数の配設部２０において、隣り合う配設部２０の劣化促進順位の差が所定値以下とすることができる。例えば、隣り合う配設部２０の劣化促進順位の差を３以下、好ましくは２以下、より好ましくは１以下とすることができ、本実施形態では、１以下としている。 In the plurality of arrangement portions 20, the difference in the deterioration promotion order of the adjacent arrangement portions 20 can be set to a predetermined value or less. For example, the difference in the deterioration promotion order of the adjacent arrangement portions 20 can be 3 or less, preferably 2 or less, more preferably 1 or less, and in the present embodiment, it is 1 or less.

複数の二次電池モジュール１０は、第１二次電池モジュール１１、第２二次電池モジュール１２、第３二次電池モジュール１３、第４二次電池モジュール１４、第５二次電池モジュール１５、第６二次電池モジュール１６、第７二次電池モジュール１７の７個を含む。そして、本実施形態では二次電池モジュール１０として使用履歴を有する再利用品を用いており、各二次電池モジュール１１～１７は使用履歴に応じた劣化が生じている。具体的には、図２に示すように、各二次電池モジュール１１～１７の満充電容量はそれぞれ、使用履歴を有しない新品の状態では破線Ｆで示した状態であったが、それぞれ使用に伴って劣化して実線で示した状態まで低下している。そして、満充電容量の低下度が多いほど劣化度が大きいことを示している。従って、二次電池モジュール１１～１７において、劣化度の大きい順位は、第１二次電池モジュール１１が第１位、第７二次電池モジュール１７が第２位、第２二次電池モジュール１２が第３位、第６二次電池モジュール１６が第４位、第３二次電池モジュール１３が第５位、第５二次電池モジュール１５が第６位、第４二次電池モジュール１４が第７位となっている。 The plurality of secondary battery modules 10 include a primary secondary battery module 11, a secondary secondary battery module 12, a third secondary battery module 13, a fourth secondary battery module 14, a fifth secondary battery module 15, and a first. 6 Includes 7 secondary battery modules 16 and 7 secondary battery modules 17. In the present embodiment, a reused product having a usage history is used as the secondary battery module 10, and each of the secondary battery modules 11 to 17 is deteriorated according to the usage history. Specifically, as shown in FIG. 2, the full charge capacity of each of the secondary battery modules 11 to 17 was shown by the broken line F in the new state having no usage history, but each of them can be used. Along with this, it deteriorates and drops to the state shown by the solid line. It is shown that the greater the degree of decrease in the full charge capacity, the greater the degree of deterioration. Therefore, in the secondary battery modules 11 to 17, the primary secondary battery module 11 is ranked first, the seventh secondary battery module 17 is ranked second, and the secondary battery module 12 is ranked second in the order of the degree of deterioration. 3rd place, 6th secondary battery module 16 is 4th place, 3rd secondary battery module 13 is 5th place, 5th secondary battery module 15 is 6th place, 4th secondary battery module 14 is 7th place. It is ranked.

そして、図２に示すように、本実施形態では、劣化度の最も小さい第４二次電池モジュール１４が劣化促進上位グループ２０１に属する配設部２０に配設されている。より詳細には、劣化度の最も小さい第４二次電池モジュール１４は、劣化促進順位が最も小さい最上位の第４配設部２４に配設されている。また、さらに、本実施形態では、二次電池モジュール１１～１７は、劣化度の小さいものほど、劣化促進順位が小さい上位の配設部２０に配設されている。 Then, as shown in FIG. 2, in the present embodiment, the fourth secondary battery module 14 having the smallest degree of deterioration is arranged in the arrangement portion 20 belonging to the deterioration promotion upper group 201. More specifically, the fourth secondary battery module 14 having the smallest degree of deterioration is arranged in the fourth arrangement portion 24 having the lowest degree of deterioration promotion. Further, in the present embodiment, the secondary battery modules 11 to 17 are arranged in the higher disposition portion 20 having a smaller deterioration promotion order as the degree of deterioration is smaller.

また、本実施形態では、複数の二次電池モジュール１０を劣化度が中央値よりも小さい劣化度小グループ１０１と、劣化度が中央値以上である劣化度大グループ１０２とに分けることができる。なお、劣化度の中央値は、劣化度の順位に基づいて、劣化促進順位の中央値と同様に規定することができる。本実施形態では、複数の二次電池モジュール１０における劣化度の順位の中央値は４であるため、劣化度小グループ１０１は第３二次電池モジュール１３、第４二次電池モジュール１４及び第５二次電池モジュール１５からなり、劣化度大グループ１０２は第１二次電池モジュール１１、第２二次電池モジュール１２、第６二次電池モジュール１６及び第７二次電池モジュール１７からなる。 Further, in the present embodiment, the plurality of secondary battery modules 10 can be divided into a small deterioration degree group 101 having a deterioration degree smaller than the median value and a large deterioration degree group 102 having a deterioration degree equal to or higher than the median value. The median deterioration degree can be defined in the same manner as the median deterioration promotion order based on the deterioration degree ranking. In the present embodiment, since the median value of the order of deterioration degree in the plurality of secondary battery modules 10 is 4, the deterioration degree small group 101 is the third secondary battery module 13, the fourth secondary battery module 14, and the fifth. The secondary battery module 15 is composed of the secondary battery module 15, and the deterioration degree group 102 is composed of the primary secondary battery module 11, the secondary secondary battery module 12, the sixth secondary battery module 16, and the seventh secondary battery module 17.

そして、本実施形態では、図２に示すように、劣化度小グループ１０１に属する二次電池モジュール１０は劣化促進上位グループ２０１に属する配設部２０に配設されている。より詳細には、最も劣化度の小さい第４二次電池モジュール１４は劣化促進順位が最も小さい最上位の第４配設部２４に配設されている。一方、劣化度大グループ１０２に属する二次電池モジュール１０は劣化促進下位グループ２０２に属する配設部２０に配設されている。より詳細には、最も劣化度の大きい第１電池モジュール１１は劣化促進順位が最も大きい最下位の第１配設部２１に配設されている。そして、本実施形態では、複数の二次電池モジュール１０は、劣化度が小さいものほど、劣化促進順位の小さい上位の配設部２０に配設されている。 Then, in the present embodiment, as shown in FIG. 2, the secondary battery module 10 belonging to the deterioration degree small group 101 is arranged in the arrangement portion 20 belonging to the deterioration promotion upper group 201. More specifically, the fourth secondary battery module 14 having the smallest degree of deterioration is disposed in the fourth arrangement portion 24 having the lowest degree of deterioration promotion. On the other hand, the secondary battery module 10 belonging to the deterioration degree group 102 is arranged in the arrangement portion 20 belonging to the deterioration promotion lower group 202. More specifically, the first battery module 11 having the highest degree of deterioration is arranged in the lowest first arrangement portion 21 having the highest degree of deterioration promotion. Further, in the present embodiment, the plurality of secondary battery modules 10 are arranged in the higher disposition portion 20 having a smaller deterioration promotion order as the degree of deterioration is smaller.

複数の二次電池モジュール１０は、隣り合う二次電池モジュール１０の劣化度の差が所定値以下とすることができる。例えば、隣り合う二次電池モジュール１０の劣化度の順位の差を３以下、好ましくは２以下、より好ましくは１以下とすることができ、本実施形態では、図２に示すように、２以下としている。 In the plurality of secondary battery modules 10, the difference in the degree of deterioration of the adjacent secondary battery modules 10 can be set to a predetermined value or less. For example, the difference in the order of deterioration of the adjacent secondary battery modules 10 can be 3 or less, preferably 2 or less, more preferably 1 or less, and in the present embodiment, 2 or less as shown in FIG. It is supposed to be.

また、本実施形態では、図２に示すように、複数の二次電池モジュール１０における劣化度の最大と最小の差Ｐ１を所定値Ｐ０以下としている。本実施形態では、当該所定値Ｐ０は、組電池１における故障判定の基準値としている。本実施形態の組電池１は、複数の二次電池モジュール１０における劣化度の最大と最小の差Ｐ１が所定値Ｐ０を超えると、当該組電池１に故障が生じていると判定されるように構成されている。 Further, in the present embodiment, as shown in FIG. 2, the difference P1 between the maximum and the minimum degree of deterioration in the plurality of secondary battery modules 10 is set to a predetermined value P0 or less.

The difference P2 between the maximum and the minimum degree of deterioration in the secondary battery module 10 of No. 1 becomes small. As a result, the difference P2 between the maximum and the minimum can be maintained within the predetermined value P0 while ensuring that the battery performance of the secondary battery module 10 is uniform. As a result, the life is extended and the performance of the assembled battery 1 is improved.

次に、本実施形態の組電池１における作用効果について、詳述する。
組電池１においては、劣化促進上位グループ２０１に属する配設部２０に配設された二次電池モジュール１０は劣化が進みやすい。そして、劣化促進上位グループ２０１に属する配設部２０に最も劣化度の小さい第４二次電池モジュール１４が配設されているため、劣化促進上位グループ２０１に属する配設部２０に劣化度の大きい他の二次電池モジュール１０が配設される場合に比べて、組電池１全体としての性能を向上させることができる。そして、劣化度の比較的大きい二次電池モジュール１０を劣化促進下位グループ２０２に属する他の配設部２０に配設することができるため、結果として二次電池モジュール１０の再利用率向上に寄与することができる。 Next, the operation and effect of the assembled battery 1 of the present embodiment will be described in detail.
In the assembled battery 1, the secondary battery module 10 arranged in the arrangement portion 20 belonging to the deterioration promotion upper group 201 tends to deteriorate. Since the fourth secondary battery module 14 having the smallest degree of deterioration is arranged in the arrangement portion 20 belonging to the deterioration promotion upper group 201, the arrangement portion 20 belonging to the deterioration promotion upper group 201 has a large degree of deterioration. Compared with the case where the other secondary battery module 10 is arranged, the performance of the assembled battery 1 as a whole can be improved. Further, since the secondary battery module 10 having a relatively large degree of deterioration can be arranged in another arrangement portion 20 belonging to the deterioration promotion lower group 202, as a result, it contributes to the improvement of the reuse rate of the secondary battery module 10. can do.

また、本実施形態では、複数の二次電池モジュール１０のうち最も劣化度の大きい第１二次電池モジュール１１は、劣化促進下位グループ２０２に属する配設部２０に配設されている。これにより、最も劣化度の大きい第１二次電池モジュール１１の劣化の進行を遅らせることができるため、組電池１の長寿命化を図って、組電池１の性能をさらに向上することができる。なお、本実施形態では、最も劣化度の大きい第１二次電池モジュール１１は、劣化促進下位グループ２０２における劣化促進順位が最も大きい最下位の第１配設部２１に配設されることとしたが、これに替えて、図４に示す変形形態１のように、最も劣化度の大きい第１二次電池モジュール１１を劣化促進下位グループ２０２に属する他の配設部２０である第２配設部２２に配設することとしてもよい。 Further, in the present embodiment, the primary secondary battery module 11 having the highest degree of deterioration among the plurality of secondary battery modules 10 is arranged in the arrangement portion 20 belonging to the deterioration promotion lower group 202. As a result, the progress of deterioration of the primary secondary battery module 11 having the highest degree of deterioration can be delayed, so that the life of the assembled battery 1 can be extended and the performance of the assembled battery 1 can be further improved. In the present embodiment, the primary secondary battery module 11 having the highest degree of deterioration is arranged in the lowest first arrangement portion 21 having the highest deterioration promotion order in the deterioration promotion lower group 202. However, instead of this, as in the modified form 1 shown in FIG. 4, the first secondary battery module 11 having the largest degree of deterioration is the second arrangement portion 20 which is another arrangement portion 20 belonging to the deterioration promotion lower group 202. It may be arranged in the portion 22.

また、本実施形態では、複数の二次電池モジュール１０を劣化度の小さい劣化度小グループ１０１と、劣化度の大きい劣化度大グループ１０２とに分けたとき、劣化度小グループ１０１に属する二次電池モジュール１０は、劣化促進上位グループ２０１に属する配設部２０に配設されている。これにより、劣化度の小さい二次電池モジュール１０が劣化しやすい配設部２０に配置されることになるため、組電池１に劣化度の大きい二次電池モジュール１０が含まれていたとしても組電池１全体として性能を高く維持することができる。なお、本実施形態では、劣化度小グループ１０１に属する最も劣化度が小さい第４二次電池モジュール１４を、劣化促進上位グループ２０１に属する最も劣化促進順位が小さい第４配設部２４に配設することとしたが、これに替えて、図５に示す変形形態２のように、最も劣化度が小さい第４二次電池モジュール１４を、劣化促進上位グループ２０１に属する他の配設部２０である第５配設部２５に配設することとしてもよい。 Further, in the present embodiment, when the plurality of secondary battery modules 10 are divided into a deterioration degree small group 101 having a small deterioration degree and a deterioration degree large group 102 having a large deterioration degree, the secondary battery modules 10 belong to the deterioration degree small group 101. The battery module 10 is arranged in an arrangement portion 20 belonging to the deterioration promotion upper group 201. As a result, the secondary battery module 10 having a small degree of deterioration is arranged in the arrangement portion 20 which is easily deteriorated. Therefore, even if the assembled battery 1 includes the secondary battery module 10 having a large degree of deterioration, the assembled battery module 10 is assembled. The performance of the battery 1 as a whole can be maintained high. In the present embodiment, the fourth secondary battery module 14 belonging to the small deterioration degree group 101 and having the smallest deterioration degree is arranged in the fourth arrangement portion 24 belonging to the deterioration promotion upper group 201 and having the smallest deterioration promotion order. However, instead of this, as in the modified form 2 shown in FIG. 5, the fourth secondary battery module 14 having the smallest degree of deterioration is mounted on the other arrangement portion 20 belonging to the deterioration promotion upper group 201. It may be arranged in a certain fifth arrangement part 25.

As a result, the performance of the assembled battery 1 as a whole can be further improved.

また、本実施形態では、複数の配設部２０において、隣り合う配設部２０の劣化促進順位の差が所定値以下である。これにより、組電池１において隣り合う配設部２０の間で互いの二次電池モジュール１０の電池状態の差を検出して故障判定や電池状態のチェックを行う場合に、誤判定の発生を抑制することができ、組電池１の性能の向上を図ることができる。 Further, in the present embodiment, the difference in the deterioration promotion order of the adjacent arrangement portions 20 in the plurality of arrangement portions 20 is a predetermined value or less. As a result, when the difference in the battery state of the secondary battery modules 10 is detected between the adjacent arrangement portions 20 in the assembled battery 1 to perform a failure determination or a battery state check, the occurrence of erroneous determination is suppressed. It is possible to improve the performance of the assembled battery 1.

また、本実施形態では、複数の二次電池モジュール１０において、隣り合う二次電池モジュール１０の劣化度の差が所定値以下である。これにより、組電池１において隣り合う二次電池モジュール１０の電池状態の差を検出して故障判定や電池状態のチェックを行う場合に、誤判定の発生を抑制することができ、組電池１の性能の向上を一層図ることができる。 Further, in the present embodiment, in the plurality of secondary battery modules 10, the difference in the degree of deterioration of the adjacent secondary battery modules 10 is not more than a predetermined value. As a result, when the difference in the battery states of the adjacent secondary battery modules 10 is detected in the assembled battery 1 to perform a failure determination or a battery status check, it is possible to suppress the occurrence of erroneous determination of the assembled battery 1. Performance can be further improved.

また、本実施形態では、複数の二次電池モジュール１０における劣化度の最大と最小の差が所定値以下である。これにより、組電池１において複数の二次電池モジュール１０における劣化度の最大と最小の差を検出して故障判定や電池状態のチェックを行う場合に、誤判定の発生を抑制することができ、組電池１の性能の向上を一層図ることができる。 Further, in the present embodiment, the difference between the maximum and the minimum degree of deterioration in the plurality of secondary battery modules 10 is a predetermined value or less. As a result, it is possible to suppress the occurrence of erroneous determination when the difference between the maximum and the minimum of the degree of deterioration in the plurality of secondary battery modules 10 is detected in the assembled battery 1 to determine the failure and check the battery status. The performance of the assembled battery 1 can be further improved.

また、本実施形態では、劣化促進順位は、各配設部２０における温度上昇速度に基づいて決定される。これにより、各配設部２０における劣化のしやすさを的確に反映した劣化促進順位を導き出すことができるため、組電池１の性能の向上を一層図ることができる。 Further, in the present embodiment, the deterioration promotion order is determined based on the temperature rise rate in each of the arrangement portions 20. As a result, it is possible to derive a deterioration promotion order that accurately reflects the susceptibility to deterioration in each of the arrangement portions 20, so that the performance of the assembled battery 1 can be further improved.

また、本実施形態では、二次電池モジュール１０の劣化度は、二次電池モジュール１０の満充電容量の低下度に基づいて決定している。これにより、二次電池モジュール１０の劣化度を高精度に導き出すことができるため、組電池１の性能の向上を一層図ることができる。なお、二次電池モジュール１０の満充電容量の低下度に替えて、二次電池モジュール１０の抵抗の上昇度に基づいて決定したり、二次電池モジュール１０の自己放電速度の増加度に基づいて決定することとしてもよい。この場合も本実施形態と同等の作用効果を奏する。 Further, in the present embodiment, the degree of deterioration of the secondary battery module 10 is determined based on the degree of decrease in the full charge capacity of the secondary battery module 10. As a result, the degree of deterioration of the secondary battery module 10 can be derived with high accuracy, so that the performance of the assembled battery 1 can be further improved. Instead of the degree of decrease in the full charge capacity of the secondary battery module 10, it is determined based on the degree of increase in the resistance of the secondary battery module 10, or based on the degree of increase in the self-discharge rate of the secondary battery module 10. It may be decided. In this case as well, the same effect as that of the present embodiment is obtained.
