以下、図面により本発明の一実施形態について説明する。
先ず、第１実施例について説明する。
図１は、本発明に係るリチウムイオン電池のモジュールの斜視図を示す。
モジュール１は、薄膜状の正極、負極及びセパレータが交互に層状に重ね合うように巻かれた電極束を絶縁材耐熱樹脂（セルケース）に入れ電解液とともに密閉して一つの金属電池ケースに収納した電池セル２を複数個直列に並べたものであり、隣り合う電池セル２同士が一定の間隔をあけて配置されるようにモジュール中蓋６で規制されて構成されている。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, the first embodiment will be described.
FIG. 1 is a perspective view of a module of a lithium ion battery according to the present invention.
In the module 1, an electrode bundle in which thin film-like positive electrodes, negative electrodes, and separators are alternately stacked in layers is put in an insulating material heat-resistant resin (cell case) and hermetically sealed with an electrolytic solution and stored in one metal battery case. A plurality of battery cells 2 are arranged in series, and the adjacent battery cells 2 are regulated by a module inner lid 6 so as to be arranged at a predetermined interval.

電池セル２には、正極から伸びた正極端子３ａと負極から伸びた負極端子３ｂがそれぞれ突出しており、ここでは電池セル２の上部両端にそれぞれ設けられている。
そして、当該正極端子３ａは隣り合う電池セル２の負極端子３ｂと、当該負極端子３ｂはさらに隣り合う電池セル２の正極端子３ａと接続するようにバスバー７が配設されている。 A positive electrode terminal 3 a extending from the positive electrode and a negative electrode terminal 3 b extending from the negative electrode protrude from the battery cell 2, respectively, and are provided at both upper ends of the battery cell 2 here.
And the bus bar 7 is arrange | positioned so that the said positive electrode terminal 3a may connect with the negative electrode terminal 3b of the adjacent battery cell 2, and the said negative electrode terminal 3b further with the positive electrode terminal 3a of the adjacent battery cell 2. FIG.

また、正極端子３ａ及び負極端子３ｂ（電極端子）にはそれぞれ、互いに向かって伸びるセル端子４が設けられており、このセル端子４には周縁がねじ切りされた孔（第１の孔、第１の結合部）５が設けられている。
このように、モジュール１では、隣り合う電池セル２同士が正極端子３ａと負極端子３ｂの向きが互いに反対になるように配置され、これらの電池セル２が直列に接続されるように隣り合う正極端子３ａ及び負極端子３ｂとがバスバー７により接続され、電極端子３ａ、３ｂから伸びるセル端子４が各電池セル２の中央で向かい合うように位置し、各電池セル２が一定の間隔をあけてモジュール中蓋６により規制され束ねられることにより電池セル２のモジュール化が図られている。 Each of the positive terminal 3a and the negative terminal 3b (electrode terminal) is provided with a cell terminal 4 extending toward each other. The cell terminal 4 has a hole (first hole, first hole) whose peripheral edge is threaded. 5) is provided.
Thus, in the module 1, the adjacent battery cells 2 are disposed so that the directions of the positive electrode terminal 3a and the negative electrode terminal 3b are opposite to each other, and the adjacent positive electrodes so that these battery cells 2 are connected in series. The terminal 3a and the negative electrode terminal 3b are connected by the bus bar 7, the cell terminals 4 extending from the electrode terminals 3a and 3b are positioned so as to face each other at the center of each battery cell 2, and each battery cell 2 is spaced apart from each other by a module. The battery cell 2 is modularized by being regulated and bundled by the inner lid 6.

また、バスバー７による正極端子３ａと負極端子３ｂの接続はモジュール１間での接続にも用いられ、これにより複数のモジュール１は直列に接続され、モジュール１の集合体として電池パックが形成される。
図２は、第１実施例に係る基板１０を固定したモジュール１の平面図を示す。
基板１０には、長辺側両端にモジュール１を構成する電池セル２のセル端子４の孔５と同数の孔（第２の孔、第２の結合部）１１が設けられている。また、基板１０上には各電池セル２内の電圧情報を処理する演算処理装置１４及び孔１１の周縁部と演算処理装置１４とを電気的に結ぶ回路１２が設けられている。 Further, the connection between the positive electrode terminal 3 a and the negative electrode terminal 3 b by the bus bar 7 is also used for connection between the modules 1, whereby a plurality of modules 1 are connected in series, and a battery pack is formed as an assembly of the modules 1. .
FIG. 2 is a plan view of the module 1 to which the substrate 10 according to the first embodiment is fixed.
The substrate 10 is provided with the same number of holes (second holes, second coupling portions) 11 as the holes 5 of the cell terminals 4 of the battery cells 2 constituting the module 1 at both ends on the long side. On the substrate 10, an arithmetic processing device 14 that processes voltage information in each battery cell 2 and a circuit 12 that electrically connects the peripheral portion of the hole 11 and the arithmetic processing device 14 are provided.

基板１０は、セル端子４の上に孔５と孔１１とが重なる位置に配置され、ボルト（接合手段）が孔１１を貫通し孔５周縁のねじと螺合することで、セル端子４と接合されている。すなわち、基板１０は、モジュール１の電極端子間の中央帯域においてモジュール１を構成する電池セル２に固定され、電池セル２と同様にモジュール化されている。
これにより、セル端子４のうち孔５の周縁部と基板１０の回路１２のうち孔１１の周縁部とが接触し、電極３からセル端子４に伝わる各電池セル２の電圧情報が、セル端子４と基板１０との接触部分から回路１２を介して演算処理装置１４に送られ処理される。 The substrate 10 is disposed at a position where the hole 5 and the hole 11 overlap with each other on the cell terminal 4, and a bolt (joining means) passes through the hole 11 and is screwed with a screw around the periphery of the hole 5. It is joined. That is, the substrate 10 is fixed to the battery cell 2 constituting the module 1 in the central band between the electrode terminals of the module 1 and is modularized in the same manner as the battery cell 2.
Thereby, the peripheral part of the hole 5 in the cell terminal 4 and the peripheral part of the hole 11 in the circuit 12 of the substrate 10 are in contact with each other, and the voltage information of each battery cell 2 transmitted from the electrode 3 to the cell terminal 4 is the cell terminal. 4 is sent from the contact portion between the substrate 10 and the substrate 10 to the arithmetic processing unit 14 via the circuit 12 for processing.

なお、この場合において、バスバー７により接続される電極間の電位差はゼロなので、バスバー７で接続されている電極３から伸びるセル端子４のうちいずれか一方は、基板１０と結合されていなくてもよい。
すなわち、図２に示されるモジュール１は４つの電池セル２から構成され、セル端子４に設けられた孔５及び基板１０に設けられた孔１１はそれぞれ８つあるが、バスバー７で接続されているセル端子４のうちいずれか一方については必ずしも基板１０と結合されていなくてもよく、回路１２に接触していなくてもよい。具体的には、ここではバスバー７は３本設けられているので、セル端子４と基板１０とは５箇所で固定されていればよい。 In this case, since the potential difference between the electrodes connected by the bus bar 7 is zero, even if one of the cell terminals 4 extending from the electrode 3 connected by the bus bar 7 is not coupled to the substrate 10. Good.
That is, the module 1 shown in FIG. 2 is composed of four battery cells 2, and there are eight holes 5 provided in the cell terminal 4 and eight holes 11 provided in the substrate 10, but they are connected by the bus bar 7. Any one of the cell terminals 4 may not be coupled to the substrate 10 and may not be in contact with the circuit 12. Specifically, since three bus bars 7 are provided here, the cell terminals 4 and the substrate 10 may be fixed at five locations.

このように、本発明の第１実施例では、基板１０は、モジュール１を構成する全ての電池セル２の電圧情報がセル端子４から直接入力されるよう構成されている。
従って、セル端子４と基板１０との間で無駄な配線を省くことができ、各セル端子４から入力された電圧情報を回路１２を介して１つの演算処理装置１４で処理することができる。 Thus, in the first embodiment of the present invention, the substrate 10 is configured such that voltage information of all the battery cells 2 constituting the module 1 is directly input from the cell terminals 4.
Therefore, useless wiring can be eliminated between the cell terminal 4 and the substrate 10, and voltage information input from each cell terminal 4 can be processed by one arithmetic processing unit 14 via the circuit 12.

また、セル端子４と基板１０とを直接固定するので、モジュール１に対して基板１０を固定することができ、電圧情報の伝達に必要な接触面以外に別途基板１０とモジュール１を接合する手段を設ける必要がない。
すなわち、本発明の二次電池の電圧検出装置によれば、電圧情報の伝達のための各電池セル２と基板１０との接続と、モジュール１と基板１０との接合とを同時に、かつ、モジュール単位で行うことができ、部品数ひいてはコストの削減及び作業効率の向上を図ることができる。 In addition, since the cell terminal 4 and the substrate 10 are directly fixed, the substrate 10 can be fixed to the module 1 and means for separately bonding the substrate 10 and the module 1 other than the contact surface necessary for transmitting voltage information. There is no need to provide.
That is, according to the voltage detection apparatus for a secondary battery of the present invention, the connection between each battery cell 2 and the substrate 10 for transmission of voltage information and the bonding between the module 1 and the substrate 10 are performed at the same time. This can be done in units, and the number of parts and thus the cost can be reduced and work efficiency can be improved.

ところで、基板１０には、当該基板１０と演算処理装置１４を備えていない基板１０’とを接続し、当該基板１０’に入力される電圧情報を基板１０に伝達するケーブル等（配線）を接続するためのケーブル差込口１６が設けられており、同様に基板１０’にはケーブル差込口１６’が設けられている。
詳しくは、２つのモジュール１が隣り合って位置している場合に、一方のモジュール１には基板１０が固定され、他方には基板１０’が固定されており、ケーブル差込口１６とケーブル差込口１６’とがケーブル２２で連結され、基板１０と１０’とが電気的に接続されている。 By the way, the board 10 is connected to the board 10 ′ that does not include the arithmetic processing unit 14, and a cable or the like (wiring) that transmits voltage information input to the board 10 ′ to the board 10 is connected. For this purpose, a cable insertion port 16 is provided, and similarly, a cable insertion port 16 'is provided in the substrate 10'.
Specifically, when two modules 1 are located next to each other, the board 10 is fixed to one module 1 and the board 10 'is fixed to the other module 1, and the cable insertion port 16 and the cable plug are connected to each other. The inlet 16 'is connected by a cable 22, and the substrates 10 and 10' are electrically connected.

これより、演算処理装置１４を備えていない基板１０’に入力された電圧情報がケーブル２２を介して基板１０に送られることになり、当該基板１０’に入力された電圧情報は当該基板１０上にて回路１２を介して演算処理装置１４に伝達され処理される。
このように、モジュール１が隣り合う場合には、一方のモジュール１には演算処理装置１４を備えた基板１０を固定し、他方のモジュール１には演算処理装置１４を有さない基板１０’を固定すればよくこれにより、基板１０’に入力された電圧情報をケーブル２２を介して演算処理装置１４に伝達し、演算処理装置１４において良好に処理可能である。故に、演算処理装置１４を載せた基板１つで２つのモジュールを監視することができ、モジュール１の数に対して演算処理装置１４の数を減らすことができ、部品数ひいてはコストのさらなる削減を図ることができる。 As a result, the voltage information input to the substrate 10 ′ not provided with the arithmetic processing unit 14 is sent to the substrate 10 via the cable 22, and the voltage information input to the substrate 10 ′ is on the substrate 10. Is transmitted to the arithmetic processing unit 14 via the circuit 12 and processed.
As described above, when the modules 1 are adjacent to each other, the board 10 having the arithmetic processing unit 14 is fixed to one module 1, and the board 10 ′ having no arithmetic processing unit 14 is fixed to the other module 1. As a result, the voltage information input to the substrate 10 ′ can be transmitted to the arithmetic processing device 14 via the cable 22, and can be processed satisfactorily in the arithmetic processing device 14. Therefore, it is possible to monitor two modules with one board on which the arithmetic processing unit 14 is mounted, the number of arithmetic processing units 14 can be reduced with respect to the number of modules 1, and the number of components and thus further cost reduction. Can be planned.

なお、ここでは基板１０に基板１０’を１つ接続するようにしているが、モジュール１が複数隣り合う場合において基板１０’を複数設け、基板１０にこれら複数の基板１０’を接続するようにしてもよい。
次に、第２実施例について説明する。
図３は、孔１１の周囲を浮き島状にした第２実施例に係る基板１１０の平面図を示す。 Here, one substrate 10 ′ is connected to the substrate 10. However, when a plurality of modules 1 are adjacent to each other, a plurality of substrates 10 ′ are provided, and these substrates 10 ′ are connected to the substrate 10. May be.
Next, a second embodiment will be described.
FIG. 3 is a plan view of the substrate 110 according to the second embodiment in which the periphery of the hole 11 is formed in a floating island shape.

基板１１０の浮島基板２０は、上記基板１０に設けられている孔１１の周囲を切り離して形成されており、基板本体１１０ａとは配線２４を介して接続されている。
すなわち、各浮島基板２０は基板本体１１０ａに対して他の浮島基板２０とは独立して垂直方向へ自由に移動することができ、個々の浮島基板２０とセル端子４とは他の固定箇所に影響されることなく接合される。 The floating island substrate 20 of the substrate 110 is formed by separating the periphery of the hole 11 provided in the substrate 10, and is connected to the substrate body 110 a via the wiring 24.
That is, each floating island substrate 20 can freely move in the vertical direction independently of the other floating island substrates 20 with respect to the substrate body 110a, and the individual floating island substrates 20 and the cell terminals 4 are placed at other fixed locations. Joined without being affected.

これにより、各浮島基板２０とセル端子４とはしっかりと接着して接合されるので、各電池セル２の電圧情報が確実に基板１１０に伝達され、演算処理装置１４での電圧情報の検出を高い精度で行うことができる。
なお、同様に上記基板１０’においても基板１１０’とし、本体１１０ａ’と配線２４を介し接続された浮島基板２０を設けセル端子４と接合するのがよく、これにより各電池セル２の電圧情報が基板１１０’にも確実に伝達され、基板１１０と基板１１０’とが接続されるモジュール間での電圧情報の検出の精度を高めることができる。 Thereby, since each floating island board | substrate 20 and the cell terminal 4 are adhere | attached firmly and joined, the voltage information of each battery cell 2 is reliably transmitted to the board | substrate 110, and detection of the voltage information in the arithmetic processing unit 14 is carried out. It can be performed with high accuracy.
Similarly, the substrate 10 ′ may be the substrate 110 ′, and the floating island substrate 20 connected to the main body 110a ′ via the wiring 24 may be provided and bonded to the cell terminal 4 so that the voltage information of each battery cell 2 is obtained. Is reliably transmitted to the substrate 110 ′, and the accuracy of detection of voltage information between the modules to which the substrate 110 and the substrate 110 ′ are connected can be improved.

次に、第３実施例について説明する。
図４は、基板１０と第３実施例に係る可撓部（可撓手段）３０を設けたセル端子４’との接着部分を側面から視た拡大図を示す。
可撓部３０は、セル端子４’上であって基板１０との接触部分と電極端子３ａ、３ｂとの間に設けられており、セル端子４’と基板１０とは、孔５と孔１１とが重なる位置においてボルト３２が孔１１を貫通し孔５に螺合されて締結されている。 Next, a third embodiment will be described.
FIG. 4 shows an enlarged view of a bonding portion between the substrate 10 and the cell terminal 4 ′ provided with the flexible portion (flexible means) 30 according to the third embodiment, as viewed from the side.
The flexible portion 30 is provided on the cell terminal 4 ′ and between the contact portion with the substrate 10 and the electrode terminals 3 a and 3 b, and the cell terminal 4 ′ and the substrate 10 include the hole 5 and the hole 11. The bolt 32 penetrates through the hole 11 and is screwed into the hole 5 at a position where they overlap.

このように、セル端子４’を支える電極端子３ａ、３ｂと、セル端子４’と基板１０との接触部分との間に可撓部３０が設けられることで、セル端子４’は可撓部３０により上下方向に撓むことが可能であり、セル端子４’と基板１０とをしっかり接触させてボルト３２により締結することができる。
これにより、セル端子４’と基板１０とがしっかりと接着した状態で接合されるので、セル端子４’から基板１０へ電圧情報を確実に基板１０に伝達することができる。 As described above, the flexible terminal 30 is provided between the electrode terminals 3a and 3b that support the cell terminal 4 'and the contact portion between the cell terminal 4' and the substrate 10, so that the cell terminal 4 'is flexible. 30, the cell terminal 4 ′ and the substrate 10 can be firmly brought into contact with each other and fastened by the bolt 32.
Thereby, since cell terminal 4 'and board | substrate 10 are joined in the state which adhered firmly, voltage information can be reliably transmitted to board | substrate 10 from cell terminal 4' to the board | substrate 10. FIG.

なお、ここでは、可撓部３０をセル端子４’上に設けるようにしたが、基板１０、１０’の孔１１の周縁に可撓手段を設けるようにしてもよい。
さらに、基板１０、１０’自体が可撓性を有するようにしてもよい。
図示しないものの、例えば、一端が基板１０に接続されるとともに他端に環状部が形成され、この環状部をボルトが貫通し孔５と螺合することで他端がセル端子４に接合されるような導電性のコイルスプリングを基板１０、１０’側に設けるようにしてもよい。 Here, the flexible portion 30 is provided on the cell terminal 4 ′, but a flexible means may be provided on the periphery of the hole 11 of the substrates 10, 10 ′.
Further, the substrates 10, 10 ′ themselves may be flexible.
Although not shown, for example, one end is connected to the substrate 10 and an annular portion is formed at the other end. The other end is joined to the cell terminal 4 by a bolt passing through the annular portion and screwing into the hole 5. Such a conductive coil spring may be provided on the substrate 10, 10 ′ side.

このようにしても、セル端子４と基板１０、１０’とはコイルスプリングの伸縮により導電性のコイルスプリングを介してしっかり接触した状態となるので、セル端子４から基板１０、１０’へ電圧情報を確実に伝達することができる。
また、セル端子４’と基板１０とはボルト３２により接合されているが、接合手段はボルトに限るものではなく、例えば、スナップフィットでの嵌め込みによる結合の他、樹脂クリップによる方法を用いるもの、熱溶着などの締結構造を有するものであってもよい。 Even in this case, since the cell terminal 4 and the substrates 10 and 10 ′ are in firm contact via the conductive coil spring due to the expansion and contraction of the coil spring, voltage information is transferred from the cell terminal 4 to the substrates 10 and 10 ′. Can be transmitted reliably.
Further, the cell terminal 4 ′ and the substrate 10 are joined by the bolt 32, but the joining means is not limited to the bolt, for example, a method using a resin clip in addition to the coupling by fitting with a snap fit, It may have a fastening structure such as heat welding.
