Description

本発明は、複数の蓄電素子列を並列接続する並列接続蓄電システムに関する。   The present invention relates to a parallel connection power storage system in which a plurality of power storage element arrays are connected in parallel.

近年、車両の省エネルギー化などを目的として大容量の蓄電装置の適用が進められている。蓄電装置の大容量化のために複数の蓄電池を並列に接続して並列接続蓄電システムを構成する場合、運転冗長性を持たせ、並列アンバランスに伴って発生する横流を防止する観点から、各蓄電池を１並列ごとにシステムから切り離すための切り離しスイッチを設けることが考えられる。   In recent years, application of large-capacity power storage devices has been promoted for the purpose of energy saving of vehicles. When configuring a parallel-connected power storage system by connecting a plurality of storage batteries in parallel for increasing the capacity of the power storage device, from the viewpoint of providing operational redundancy and preventing cross currents generated due to parallel imbalance, It is conceivable to provide a disconnect switch for disconnecting the storage battery from the system for each parallel.

このような並列接続蓄電システムにおいて、長時間運転しない状態においては、蓄電池の電圧が印加されている部位をできるだけ最小限にするために、切り離しスイッチによってシステムから各蓄電池を切り離しておくことが通常行われる。しかしながら複数の蓄電池ごとの自己放電特性の違いに起因して、長時間放置後に再投入する時に複数の蓄電池それぞれの電圧が異なる場合がある。そのような複数の蓄電池ごとに放電深度が異なっている状態でスイッチを投入して並列接続すると、蓄電池ごとの電圧差によって大きな横流電流が発生し、過電流や異常発熱などの不適合が発生することが懸念される。   In such a parallel-connected power storage system, when the battery is not operated for a long time, in order to minimize the portion to which the voltage of the storage battery is applied, it is normal practice to disconnect each storage battery from the system with a disconnect switch. Is called. However, due to the difference in self-discharge characteristics for each of the plurality of storage batteries, the voltage of each of the plurality of storage batteries may differ when the battery is turned on again after being left for a long time. When a switch is turned on and connected in parallel with different discharge depths for each of these multiple storage batteries, a large cross current will be generated due to the voltage difference of each storage battery, resulting in incompatibilities such as overcurrent and abnormal heat generation. Is concerned.

これに対し、図６に示すように、リチウムイオン電池のような蓄電素子１１ａ，１１ｂ，１１ｃを適数個直列接続して構成した蓄電素子列Ｂａｔ１〜Ｂａｔ３を並列接続し、例えばＤＣ／ＤＣコンバータＤ−ＣＯＮＶのような充放電制御装置を複数の蓄電素子列Ｂａｔ１〜Ｂａｔ３それぞれに対して設け、これらＤＣ／ＤＣコンバータＤ−ＣＯＮＶ間の電流アンバランスを個別に管理する並列接続蓄電システムが提案されている。   On the other hand, as shown in FIG. 6, power storage element rows Bat1 to Bat3 configured by connecting a suitable number of power storage elements 11a, 11b, and 11c such as lithium ion batteries in series are connected in parallel, for example, a DC / DC converter. A parallel connection power storage system is proposed in which a charge / discharge control device such as D-CONV is provided for each of a plurality of power storage element arrays Bat1 to Bat3, and current imbalance between these DC / DC converters D-CONV is individually managed. ing.

ところが、この提案されている並列接続蓄電システムのように、ＤＣ／ＤＣコンバータを蓄電素子列の並列分だけ個別に複数設置することは、システムのコスト上昇および装置の大型化を招くことになり、簡単なスイッチのみで成立するシステムの構築が求められていた。
鉄道サイバネ２００６年論文番号６０６ However, as in the proposed parallel-connected power storage system, installing a plurality of DC / DC converters separately for the parallel storage element array leads to an increase in system cost and an increase in the size of the device. There was a demand for the construction of a system that could be realized only with simple switches.

本発明は、以上の従来の技術的課題を解決するためになされたもので、従来のような並列投入時の大きな横流電流に起因した過電流や異常発熱などの不適合の発生を防ぐことができる並列接続蓄電システムを提供することを目的とする。   The present invention has been made to solve the above-described conventional technical problems, and can prevent occurrence of incompatibility such as overcurrent and abnormal heat generation caused by a large cross current at the time of parallel input as in the prior art. It aims at providing a parallel connection electrical storage system.

本発明は、充放電が可能な蓄電素子を１又は複数個直列に接続して蓄電素子列とし、複数の蓄電素子列を並列に接続した並列接続蓄電システムにおいて、前記蓄電素子列ごとに当該システムに接続と切離しを行うスイッチと、前記複数の蓄電素子列間の電圧差を検出する電圧監視手段と、前記電圧監視手段が検出した電圧差が所定値以内の蓄電素子列が１又は複数存在する時に当該蓄電素子列に対する前記スイッチのみを投入する制御手段とを備えた並列接続蓄電システムを特徴とする。   The present invention relates to a parallel connection power storage system in which one or a plurality of chargeable / dischargeable power storage elements are connected in series to form a power storage element array, and the plurality of power storage element arrays are connected in parallel. There are one or a plurality of switches for connecting and disconnecting to the power supply, voltage monitoring means for detecting a voltage difference between the plurality of power storage element arrays, and one or a plurality of power storage element arrays having a voltage difference detected by the voltage monitoring means within a predetermined value. Sometimes, it is characterized by a parallel-connected power storage system provided with control means for turning on only the switch for the power storage element array.

また、本発明は、充放電が可能な蓄電素子を１又は複数個直列に接続して蓄電素子列とし、複数の蓄電素子列を並列に接続した並列接続蓄電システムにおいて、前記蓄電素子列ごとに当該システムに接続と切離しを行うスイッチと、前記複数の蓄電素子列それぞれの蓄電残量を監視する蓄電残量監視手段を備え、前記複数の蓄電素子列のうち、前記蓄電残量監視手段が監視する蓄電残量が他の蓄電素子列の蓄電残量よりも所定値以上に不均衡となっている蓄電素子列が存在する時に当該蓄電素子列に対する前記スイッチを切り離す制御手段とを備えた並列接続蓄電システムを特徴とする。   Further, the present invention provides a parallel connection power storage system in which one or a plurality of chargeable / dischargeable power storage elements are connected in series to form a power storage element array, and the plurality of power storage element arrays are connected in parallel. A switch for connecting to and disconnecting from the system; and a remaining power storage monitoring means for monitoring a remaining power storage capacity of each of the plurality of power storage element arrays, wherein the remaining power storage monitoring means monitors among the plurality of power storage element arrays. Parallel connection provided with a control means for disconnecting the switch for the storage element row when there is a storage element row in which the remaining storage amount is unbalanced to a predetermined value or more than the remaining storage amount of the other storage element row It features a power storage system.

本発明の並列接続蓄電システムによれば、スイッチ投入前に並列間の電圧差を検出し、電圧差が一定値以下のもののみスイッチ投入することで、並列投入時の大きな横流電流に起因した、過電流や異常発熱などの不適合の発生を防ぐことができる。   According to the parallel-connected power storage system of the present invention, the voltage difference between the parallels is detected before the switch is turned on, and the voltage difference is switched on only for a certain value or less, resulting in a large cross current at the time of turning on the parallel, The occurrence of nonconformities such as overcurrent and abnormal heat generation can be prevented.

また、本発明の並列接続蓄電システムによれば、複数の蓄電素子列のうち蓄電残量が他の蓄電素子列の蓄電残量よりも所定値以上に不均衡となっている蓄電素子列が存在する時に当該蓄電素子列を切り離すことで、並列接続運転中に蓄電残量に大きなアンバランスが発生したとしても、大きな電圧差による横流電流に起因した過電流や異常発熱などの不適合の発生を防ぐことができる。   Further, according to the parallel-connected power storage system of the present invention, there is a power storage element array in which the remaining power storage amount is more than a predetermined value than the remaining power storage capacity of the other power storage element arrays. By disconnecting the power storage element array during operation, even if a large imbalance occurs in the remaining power during parallel connection operation, it prevents the occurrence of nonconformities such as overcurrent and abnormal heat generation due to cross current due to a large voltage difference. be able to.

以下、本発明の実施の形態を図に基づいて詳説する。図１は、本発明の１つの実施の形態の並列接続蓄電システムを示している。本実施の形態の並列接続蓄電システムでは、複数個（本実施の形態では３個）の蓄電素子１１ａ，１１ｂ，１１ｃが直列接続されて構成される蓄電素子列１が第１〜第３まで３列並列に配置され、これら第１〜第３の蓄電素子列Ｂａｔ１〜Ｂａｔ３それぞれに直列に第１〜第３のスイッチＳＷｂａｔ１〜ＳＷｂａｔ３が接続され、第１〜第３の蓄電素子列Ｂａｔ１〜Ｂａｔ３の開放端と第１〜第３のスイッチＳＷｂａｔ１〜ＳＷｂａｔ３の開放端とがＤＣ／ＤＣコンバータＤ−ＣＯＮＶの一側端に並列に接続されている。ＤＣ／ＤＣコンバータＤ−ＣＯＮＶの他側端は負荷ＬＤに接続されている。第１〜第３の蓄電素子列Ｂａｔ１〜Ｂａｔ３それぞれの両端には各電圧を検出する第１〜第３の電圧検出器ＤＴ１〜ＤＴ３が接続されており、それらの電圧検出信号は制御装置ＣＮＴに入力する。この制御装置ＣＮＴは、これら第１〜第３の電圧検出器ＤＴ１〜ＤＴ３の検出電圧を入力し、所定の比較演算処理に基づいて第１〜第３のスイッチＳＷｂａｔ１〜ＳＷｂａｔ３それぞれをオン／オフ制御する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a parallel-connected power storage system according to one embodiment of the present invention. In the parallel-connected power storage system according to the present embodiment, a plurality of (three in the present embodiment) power storage elements 11a, 11b, and 11c are connected in series to the first to third power storage element arrays 1. The first to third switches SWbat1 to SWbat3 are connected in series to each of the first to third storage element arrays Bat1 to Bat3, and the first to third storage element arrays Bat1 to Bat3 are connected in series. The open end and the open ends of the first to third switches SWbat1 to SWbat3 are connected in parallel to one side end of the DC / DC converter D-CONV. The other end of the DC / DC converter D-CONV is connected to the load LD. First to third voltage detectors DT1 to DT3 for detecting each voltage are connected to both ends of each of the first to third power storage element arrays Bat1 to Bat3, and these voltage detection signals are transmitted to the control device CNT. input. The control device CNT inputs the detection voltages of the first to third voltage detectors DT1 to DT3, and controls on / off of the first to third switches SWbat1 to SWbat3 based on a predetermined comparison calculation process. To do.

第１〜第３の蓄電素子列Ｂａｔ１〜Ｂａｔ３それぞれを構成する蓄電素子１１ａ，１１ｂ，１１ｃとしては、例えばリチウムイオン電池のような二次電池が用いられる。また、蓄電素子の直列接続数は、システムの規模に応じて適切な接続数に決定される。   As the power storage elements 11a, 11b, and 11c constituting each of the first to third power storage element arrays Bat1 to Bat3, for example, a secondary battery such as a lithium ion battery is used. Further, the number of power storage elements connected in series is determined as an appropriate number of connections according to the scale of the system.

次に、上記構成の並列接続蓄電システムにおける負荷接続、切り離し制御について、図２のタイムチャート、図３のフローチャートを用いて説明する。図２において、第１〜第３蓄電素子列Ｂａｔ１〜Ｂａｔ３それぞれの電圧をＶｂａｔ１，Ｖｂａｔ２，Ｖｂａｔ３で表している。タイミングＴ０の運転開始時、Ｖｂａｔ１＞Ｖｂａｔ２＞Ｖｂａｔ３の状態であったとする。この場合、演算処理上の便宜のため第１、第２、第３の蓄電素子列Ｂａｔ１，Ｂａｔ２，Ｂａｔ３それぞれに電圧の高いものから順に仮想的なバッテリ番号としてＢａｔｖ１，Ｂａｔｖ２，Ｂａｔｖ３と識別番号を付け替える。そしてそれぞれの電圧は、Ｖｂａｔｖ１，Ｖｂａｔｖ２，Ｖｂａｔｖ３とし、電圧差はそれぞれΔＶｖ１２，ΔＶｖ２３，ΔＶｖ３１とする（ステップＳＴ１，ＳＴ２）。   Next, load connection and disconnection control in the parallel connection power storage system having the above configuration will be described with reference to the time chart of FIG. 2 and the flowchart of FIG. In FIG. 2, the voltages of the first to third power storage element arrays Bat1 to Bat3 are represented by Vbat1, Vbat2, and Vbat3. Assume that Vbat1> Vbat2> Vbat3 at the start of operation at timing T0. In this case, for convenience of calculation processing, Batv1, Batv2, Batv3 and identification numbers are assigned as virtual battery numbers in order from the one with the highest voltage to each of the first, second, and third storage element arrays Bat1, Bat2, and Bat3. Replace. The respective voltages are Vbatv1, Vbatv2, and Vbatv3, and the voltage differences are ΔVv12, ΔVv23, and ΔVv31, respectively (steps ST1 and ST2).

制御装置ＣＮＴは、Ｖｂａｔｖ２に対するＶｂａｔｖ１，Ｖｂａｔｖ３の電圧差ΔＶｖ１２，ΔＶｖ２３のどちらかが所定値ΔＶｒｅｆより大きいことを検出すれば、スイッチＳＷｂａｔ１〜ＳＷｂａｔ３を同時投入することなく個別に投入すると判断する（ステップＳＴ３，ＳＴ４）。そして、制御装置ＣＮＴは、中間電圧値を示す蓄電素子列Ｂａｔｖ２を用いて運転を開始すべく、スイッチＳＷｂａｔｖ２に投入信号を送り、蓄電素子列Ｂａｔｖ２（図２ではＢａｔ２）に対するスイッチＳＷｂａｔｖ２（図２ではＳＷｂａｔ２）を投入させる。これにて外部のＤＣ／ＤＣコンバータＤ−ＣＯＮＶは負荷ＬＤに対して放電動作を開始する（タイミングＴ１；ステップＳＴ５）。   If the control device CNT detects that one of the voltage differences ΔVv12 and ΔVv23 between Vbatv1 and Vbatv3 with respect to Vbatv2 is greater than a predetermined value ΔVref, it determines that the switches SWbat1 to SWbat3 are individually turned on without simultaneously turning them on (step ST3). , ST4). Then, the control device CNT sends an input signal to the switch SWbatv2 to start operation using the storage element array Batv2 indicating the intermediate voltage value, and the switch SWbatv2 (in FIG. 2, Bat2) to the storage element array Batv2 (in FIG. 2). SWbat2) is turned on. As a result, the external DC / DC converter D-CONV starts discharging operation with respect to the load LD (timing T1; step ST5).

スイッチＳＷｂａｔｖ２が投入された蓄電素子列Ｂａｔｖ２（図２ではＢａｔ２）は放電され、放電に従い電圧Ｖｂａｔｖ２（図２ではＶｂａｔ２）が低下していく（タイミングＴ２）。この蓄電素子列Ｂａｔｖ２の電圧低下に従いその電圧Ｖｂａｔｖ２が最低の電圧を示している蓄電素子列Ｂａｔｖ３の電圧Ｖｂａｔｖ３の値に近づき、その差が所定値ΔＶｒｅｆ以下となった時、スイッチＳＷｂａｔｖ３（図２ではスイッチＳＷｂａｔ３）を並列投入する（タイミングＴ３；ステップＳＴ７にてＮＯに分岐し、ステップＳＴ９に移行）。この時の蓄電素子列Ｂａｔｖ２と蓄電素子列Ｂａｔｖ３との電圧Ｖｂａｔｖ２，Ｖｂａｔｖ３はほぼ同一となっているので並列投入に起因した過大な横流電流が両蓄電素子列Ｂａｔｖ２，Ｂａｔｖ３間に発生しない。その後、蓄電素子列Ｂａｔｖ２と充放電蓄電素子Ｂａｔｖ３との放電動作が並列に行われる（タイミングＴ４；ステップＳＴ９）。   The storage element array Batv2 (Bat2 in FIG. 2) in which the switch SWbatv2 is turned on is discharged, and the voltage Vbatv2 (Vbat2 in FIG. 2) is decreased according to the discharge (timing T2). When the voltage Vbatv2 approaches the value of the voltage Vbatv3 of the storage element row Batv3 indicating the lowest voltage in accordance with the voltage drop of the storage element row Batv2, when the difference becomes equal to or less than the predetermined value ΔVref, the switch SWbatv3 (in FIG. 2) The switch SWbat3) is turned on in parallel (timing T3; branching to NO in step ST7, and shifting to step ST9). At this time, the voltages Vbatv2 and Vbatv3 of the storage element array Batv2 and the storage element array Batv3 are substantially the same, so that an excessive cross current caused by parallel input does not occur between the storage element arrays Batv2 and Batv3. Thereafter, the discharging operation of the storage element array Batv2 and the charge / discharge storage element Batv3 is performed in parallel (timing T4; step ST9).

次に、タイミングＴ５にて、外部のＤＣ／ＤＣコンバータＤ−ＣＯＮＶは、負荷ＬＤの運転パターンに従って負荷ＬＤからの充電動作を開始したとする。この充電に従い並列運転中の蓄電素子列Ｂａｔｖ２，Ｂａｔｖ３の電圧Ｖｂａｔｖ２，Ｖｂａｔｖ３（図２では第２の蓄電素子列Ｂａｔ２の電圧Ｖｂａｔｖ、第３の蓄電素子列Ｂａｔ３の電圧Ｖｂａｔ３）は同時に上昇していく。この電圧上昇に従い蓄電素子列Ｂａｔｖ２，Ｂａｔｖ３の電圧Ｖｂａｔｖ２，Ｖｂａｔｖ３は蓄電素子列Ｂａｔｖ１の電圧Ｖｂａｔｖ１の値に近づき、その差が所定値Δｒｅｆ以下となったタイミングＴ６において、制御装置ＣＮＴは蓄電素子列Ｂａｔｖ１に対するスイッチＳＷｂａｔｖ１（図２では第１の蓄電素子列Ｂａｔ１に対するスイッチＳＷｂａｔ１）を並列投入する（ステップＳＴ１１でＮＯに分岐し、ステップＳＴ１２に移行）。このとき電圧はほぼ同一であるので並列投入に起因した過大な横流電流は発生しない。   Next, it is assumed that the external DC / DC converter D-CONV starts the charging operation from the load LD according to the operation pattern of the load LD at the timing T5. According to this charging, the voltages Vbatv2 and Vbatv3 of the storage element rows Batv2 and Batv3 (in FIG. 2, the voltage Vbatv of the second storage element row Bat2 and the voltage Vbat3 of the third storage element row Bat3) increase simultaneously. . As the voltage rises, the voltages Vbatv2 and Vbatv3 of the storage element rows Batv2 and Batv3 approach the value of the voltage Vbatv1 of the storage element row Batv1, and at the timing T6 when the difference becomes equal to or less than the predetermined value Δref, the control device CNT operates at the storage element row Batv1. Switch SWbatv1 (switch SWbat1 for the first storage element array Bat1 in FIG. 2) is turned on in parallel (branch to NO in step ST11 and shift to step ST12). At this time, since the voltages are substantially the same, an excessive cross current caused by parallel input is not generated.

こうして、第１〜第３の蓄電素子列Ｂａｔ１〜Ｂａｔ３がすべて並列接続された運転状態に移行する。この後は、これらの並列接続された３列の蓄電素子列Ｂａｔ１〜Ｂａｔ３に対して同時に充放電動作が行われる（タイミングＴ７，Ｔ８；ステップＳＴ１２）。   In this way, the operation state shifts to a state where all of the first to third power storage element rows Bat1 to Bat3 are connected in parallel. Thereafter, the charge / discharge operation is simultaneously performed on the three storage element rows Bat1 to Bat3 connected in parallel (timing T7, T8; step ST12).

尚、起動時、再起動時に蓄電素子列Ｂａｔ１〜Ｂａｔ３各々の電圧を検出し、それらの電圧差がいずれもΔＶｒｅｆ以下である場合にはステップＳＴ４にてステップＳＴ１２に直接に分岐し、スイッチＳＷｂａｔ１〜ＳＷｂａｔ３を全投入して３列並列接続運転に移行する。   It should be noted that the voltage of each of the storage element arrays Bat1 to Bat3 is detected at the time of start-up and restart, and if any of these voltage differences is equal to or less than ΔVref, the process directly branches to step ST12 in step ST4, and switches SWbat1 to SWbat1 All the SWbat3 is turned on to shift to the three-row parallel connection operation.

また、起動時、再起動時に蓄電素子列Ｂａｔ１〜Ｂａｔ３各々の電圧を検出し、最低電圧を示す蓄電素子列Ｂａｔｖ３の電圧Ｖｂａｔｖ３と中間電圧を示す蓄電素子列Ｂａｔｖ２の電圧Ｖｂａｔｖ２との電圧差ΔＶｖ２３だけが所定値ΔＶｒｅｆ以下である場合にはステップＳＴ４にてステップＳＴ９に分岐し、起動時にスイッチＳＷｂａｔｖ２，ＳＷｂａｔｖ３を同時に投入して蓄電素子列Ｂａｔｖ２，Ｂａｔｖ３の２列並列運転を開始する。そしてその後、最高電圧を示す蓄電素子列Ｂａｔｖ１の電圧Ｖｂａｔｖ１と中間電圧を示した蓄電素子列Ｂａｔｖ２の電圧Ｖｂａｔｖ２との電圧差ΔＶｖ１２が所定値ΔＶｒｅｆ以下になれば、ステップＳＴ１１にてＮＯに分岐し、スイッチＳＷｂａｔｖ１も投入して３列並列接続運転に入る（ステップＳＴ１２）。   In addition, the voltage of each of the storage element rows Bat1 to Bat3 is detected at the time of starting and restarting, and only a voltage difference ΔVv23 between the voltage Vbatv3 of the storage element row Batv3 indicating the lowest voltage and the voltage Vbatv2 of the storage element row Batv2 indicating the intermediate voltage. Is equal to or less than the predetermined value ΔVref, the process branches to step ST9 in step ST4, and switches SWbatv2 and SWbatv3 are simultaneously turned on at the time of activation to start the two-column parallel operation of the storage element columns Batv2 and Batv3. After that, if the voltage difference ΔVv12 between the voltage Vbatv1 of the storage element array Batv1 indicating the highest voltage and the voltage Vbatv2 of the storage element array Batv2 indicating the intermediate voltage is equal to or less than the predetermined value ΔVref, the process branches to NO in step ST11. The switch SWbatv1 is also turned on to start a three-row parallel connection operation (step ST12).

一方、起動時、再起動時に蓄電素子列Ｂａｔ１〜Ｂａｔ３各々の電圧を検出し、最高電圧を示す蓄電素子列Ｂａｔｖ１の電圧Ｖｂａｔｖ１と中間電圧を示す蓄電素子列Ｂａｔｖ２の電圧Ｖｂａｔｖ２との電圧差ΔＶｖ１２だけが所定値ΔＶｒｅｆ以下である場合にはステップＳＴ４にてステップＳＴ１３に分岐し、起動時にスイッチＳＷｂａｔｖ１，ＳＷｂａｔｖ２を同時に投入して蓄電素子列Ｂａｔｖ１，Ｂａｔｖ２の２列並列運転を開始する。そしてその後、最低電圧を示した蓄電素子列Ｂａｔｖ３の電圧Ｖｂａｔｖ３と中間電圧を示した蓄電素子列Ｂａｔｖ２の電圧Ｖｂａｔｖ２との電圧差ΔＶｖ２３が所定値ΔＶｒｅｆ以下になれば、ステップＳＴ１５にてＮＯに分岐し、スイッチＳＷｂａｔｖ３も投入して３列並列接続運転に入る（ステップＳＴ１２）。   On the other hand, the voltage of each of the storage element rows Bat1 to Bat3 is detected at the time of starting and restarting, and only a voltage difference ΔVv12 between the voltage Vbatv1 of the storage element row Batv1 indicating the highest voltage and the voltage Vbatv2 of the storage element row Batv2 indicating the intermediate voltage. Is equal to or less than the predetermined value ΔVref, the process branches to step ST13 in step ST4, and switches SWbatv1 and SWbatv2 are simultaneously turned on at the start to start the two-column parallel operation of the storage element columns Batv1 and Batv2. After that, if the voltage difference ΔVv23 between the voltage Vbatv3 of the storage element row Batv3 indicating the lowest voltage and the voltage Vbatv2 of the storage element row Batv2 indicating the intermediate voltage becomes equal to or less than the predetermined value ΔVref, the process branches to NO in step ST15. The switch SWbatv3 is also turned on to start the three-row parallel connection operation (step ST12).

以上の構成の並列接続蓄電システムにより、第１〜第３の全蓄電素子列Ｂａｔ１〜Ｂａｔ３を最終的に並列運転できるようにし、ＤＣ／ＤＣコンバータＤ−ＣＯＮＶを共通の１台だけ使用することでシステムコストアップや装置大型化を招くことなく、並列投入時の大きな横流電流に起因した過電流や異常発熱などの不適合の発生を防ぐことが可能になる。   By the parallel-connected power storage system having the above configuration, the first to third power storage element arrays Bat1 to Bat3 can finally be operated in parallel, and only one common DC / DC converter D-CONV is used. Without incurring an increase in system cost or an increase in the size of the apparatus, it becomes possible to prevent the occurrence of nonconformities such as overcurrent and abnormal heat generation due to a large cross current at the time of parallel charging.

次に、第１〜第３の全蓄電素子列Ｂａｔ１〜Ｂａｔ３の並列運転状態において、いずれかの蓄電素子列の蓄電残量が所定値ΔＶｒｅｆを超えて変化した場合の切り離し、再接続制御について、図４のフローチャートを用いて説明する。尚、蓄電残量は電圧と一定の関係を持つものなので、本実施の形態では蓄電素子列ごとの電圧の高低を蓄電残量の大小と見なし、蓄電素子列の電圧の高低により並列運転中の切り離し、再接続制御をする。   Next, in the parallel operation state of all the first to third power storage element arrays Bat1 to Bat3, regarding the disconnection and reconnection control when the remaining power storage capacity of any one of the power storage element arrays has changed beyond a predetermined value ΔVref, This will be described with reference to the flowchart of FIG. In addition, since the remaining amount of power storage has a certain relationship with the voltage, in this embodiment, the voltage level of each power storage element array is regarded as the level of the remaining power storage level, and the parallel operation is performed depending on the voltage level of the power storage element array. Disconnect and control reconnection.

３列の蓄電素子列Ｂａｔ１〜Ｂａｔ３の並列運転状態でそれぞれの蓄電素子列の電圧を検出し、最高電圧、中間電圧、最低電圧を示す蓄電素子列をそれぞれＢａｔｖ１，Ｂａｔｖ２，Ｂａｔｖ３とし、それぞれの電圧をＶｂａｔｖ１，Ｖｂａｔｖ２，Ｖｂａｔｖ３とする（ステップＳＴ２１〜ＳＴ２３）。そして、中間電圧を示す蓄電素子列Ｂａｔｖ２の電圧Ｖｂａｔｖ２との電圧差ΔＶｖ１２，ΔＶｖ２３を求め、所定値ΔＶｒｅｆと大小を比較する（ステップＳＴ２４，ＳＴ２７）。   The voltages of the respective storage element arrays are detected in the parallel operation state of the three storage element arrays Bat1 to Bat3, and the storage element arrays indicating the highest voltage, the intermediate voltage, and the lowest voltage are designated as Batv1, Batv2, and Batv3, respectively. Are Vbatv1, Vbatv2, and Vbatv3 (steps ST21 to ST23). Then, voltage differences ΔVv12 and ΔVv23 with respect to the voltage Vbatv2 of the storage element array Batv2 indicating the intermediate voltage are obtained, and the predetermined value ΔVref is compared with the magnitude (steps ST24 and ST27).

いま、中間電圧を示す蓄電素子列Ｂａｔｖ２に対して最高電圧を示す蓄電素子列Ｂａｔｖ１の電圧差ΔＶｖ１２が所定値ΔＶｒｅｆよりも大きくなれば、当該蓄電素子列Ｂａｔｖ１を並列接続から切り離す（ステップＳＴ２５，ＳＴ２６）。これにより、残りの２つの蓄電素子列Ｂａｔｖ２，Ｂａｔｖ３の並列運転に移行する。   Now, if the voltage difference ΔVv12 of the storage element array Batv1 indicating the highest voltage with respect to the storage element array Batv2 indicating the intermediate voltage becomes larger than the predetermined value ΔVref, the storage element array Batv1 is disconnected from the parallel connection (steps ST25 and ST26). ). As a result, the remaining two storage element rows Batv2 and Batv3 are shifted to parallel operation.

一方、中間電圧を示す蓄電素子列Ｂａｔｖ２に対して最低電圧を示す蓄電素子列Ｂａｔｖ３の電圧差ΔＶｖ２３が所定値ΔＶｒｅｆよりも大きくなれば、当該蓄電素子列Ｂａｔｖ３を並列接続から切り離す（ステップＳＴ２７，ＳＴ２８）。これにより、残りの２つの蓄電素子列Ｂａｔｖ１，Ｂａｔｖ２の並列運転に移行する。   On the other hand, when the voltage difference ΔVv23 of the storage element array Batv3 indicating the lowest voltage with respect to the storage element array Batv2 indicating the intermediate voltage becomes larger than the predetermined value ΔVref, the storage element array Batv3 is disconnected from the parallel connection (steps ST27 and ST28). ). As a result, the remaining two storage element rows Batv1, Batv2 are shifted to parallel operation.

尚、中間電圧を示す蓄電素子列Ｂａｔｖ２に対して最高電圧を示す蓄電素子列Ｂａｔｖ１の電圧差ΔＶｖ１２が所定値ΔＶｒｅｆよりも大きくなり、同時に、最低電圧を示す蓄電素子列Ｂａｔｖ３の電圧差ΔＶｖ２３も所定値ΔＶｒｅｆよりも大きくなれば、蓄電素子列Ｂａｔｖ１，Ｂａｔｖ３を共に並列接続から切り離し、蓄電素子列Ｂａｔｖ２だけの単列運転に移行する（ステップＳＴ２５でＹＥＳ、かつ、ステップＳＴ２７でもＹＥＳの場合）。   Note that the voltage difference ΔVv12 of the storage element array Batv1 indicating the maximum voltage is larger than the predetermined value ΔVref with respect to the storage element array Batv2 indicating the intermediate voltage, and at the same time, the voltage difference ΔVv23 of the storage element array Batv3 indicating the minimum voltage is also predetermined. If larger than value ΔVref, both storage element rows Batv1 and Batv3 are disconnected from the parallel connection and shifted to a single-row operation with only storage element row Batv2 (YES in step ST25 and YES in step ST27).

１列、又は２列の蓄電素子列を中間電圧を示す蓄電素子列Ｂａｔｖ２から切り離した後にも３列の蓄電素子列Ｂａｔｖ１〜Ｂａｔｖ３の電圧の監視を継続し、蓄電素子列Ｂａｔｖ１と蓄電素子列Ｂａｔｖ２との電圧差ΔＶｖ１２、あるいは蓄電素子列Ｂａｔｖ３と蓄電素子列Ｂａｔｖ２との電圧差ΔＶｖ２３が所定値ΔＶｒｅｆ以下に小さくなれば再度、該当する蓄電素子列Ｂａｔｖ１あるいはＢａｔｖ３を蓄電素子列Ｂａｔｖ２に並列接続する（ステップＳＴ３０，ＳＴ３１）。   Even after the one or two storage element arrays are disconnected from the storage element array Batv2 indicating the intermediate voltage, the monitoring of the voltages of the three storage element arrays Batv1 to Batv3 is continued, and the storage element array Batv1 and the storage element array Batv2 Or the voltage difference ΔVv23 between the storage element row Batv3 and the storage element row Batv2 becomes smaller than a predetermined value ΔVref, the corresponding storage element row Batv1 or Batv3 is again connected in parallel to the storage element row Batv2 ( Steps ST30 and ST31).

このようにして、３列の全蓄電素子列Ｂａｔ１〜Ｂａｔ３の並列接続運転状態でいずれかの蓄電素子列の電圧が大幅に低下したり上昇したりした時にはいったん該当蓄電素子列を切り離すことで、並列投入時の大きな横流電流に起因した過電流や異常発熱などの不適合の発生を防ぐことが可能になる。   In this way, when the voltage of any one of the storage element rows greatly decreases or rises in the parallel connection operation state of all the three storage element rows Bat1 to Bat3, once the corresponding storage element row is disconnected, It is possible to prevent the occurrence of nonconformities such as overcurrent and abnormal heat generation due to a large cross current when the parallel is turned on.

尚、本実施の形態にあって、制御装置ＣＮＴは全蓄電素子列Ｂａｔ１〜Ｂａｔ３の電圧値を監視しており、長期放置状態に移行する場合、各蓄電素子列に対して蓄電残量に換算して５０％以下となる電圧を示すようになるまで放電させてから運転を停止し、スイッチＳＷｂａｔ１〜ＳＷｂａｔ３それぞれを切り離す制御をすることが望ましい。   In the present embodiment, the control device CNT monitors the voltage values of all the power storage element rows Bat1 to Bat3. When the control device CNT shifts to the long-term neglected state, it is converted into the remaining power storage amount for each power storage element row. Then, it is desirable to perform control to stop the operation after discharging until the voltage reaches 50% or less, and to disconnect each of the switches SWbat1 to SWbat3.

（第２の実施の形態）図５を用いて、本発明の第２の実施の形態の並列接続蓄電システムについて説明する。本実施の形態の特徴は、制御装置ＣＮＴが蓄電素子列の並列接続数に応じて充放電電流最大制限値を可変設定することを特徴とする。尚、図５において図１に示した第１の実施の形態と共通する要素については共通の符号を付して示してある。   (Second Embodiment) A parallel-connected power storage system according to a second embodiment of the present invention will be described with reference to FIG. The feature of the present embodiment is that the control device CNT variably sets the maximum charge / discharge current limit value according to the number of parallel connection of the storage element arrays. In FIG. 5, elements common to the first embodiment shown in FIG. 1 are denoted by common reference numerals.

本実施の形態の並列接続蓄電システムでは、制御装置ＣＮＴの並列接続制御、切り離し制御は第１の実施の形態と同様である。そして、制御装置ＣＮＴは、並列接続数に応じた充放電電流最大制限値をＤＣ／ＤＣコンバータＤ−ＣＯＮＶに対して可変設定する。接続数１の時の電流最大制限値をＩ１ｉｍｉｔとし、並列接続数２の時には電流最大制限値をＩ２ｌｉｍｉｔ（＝Ｉ１ｌｉｍｉｔ＋ΔＩ）とし、並列接続数３の時には電流最大制限値をＩ３ｌｉｍｉｔ（＝Ｉ１ｌｉｍｉｔ＋２ΔＩ）とする。ＤＣ／ＤＣコンバータＤ−ＣＯＮＶは制御装置ＣＮＴから充放電電流最大制限値Ｉｌｉｍｉｔを受けて、蓄電システム側の充放電電流がこの制限値を超えないように動作する。   In the parallel connection power storage system of the present embodiment, the parallel connection control and disconnection control of the control device CNT are the same as those of the first embodiment. Then, the control device CNT variably sets the maximum charge / discharge current limit value corresponding to the number of parallel connections to the DC / DC converter D-CONV. When the number of connections is 1, the maximum current limit value is I1limit, when the number of parallel connections is 2, the current maximum limit value is I2limit (= I1limit + ΔI), and when the number of parallel connections is 3, the maximum current limit value is I3limit (= I1limit + 2ΔI). . The DC / DC converter D-CONV receives the charge / discharge current maximum limit value Ilimit from the control device CNT, and operates so that the charge / discharge current on the power storage system side does not exceed the limit value.

これにより、本実施の形態によれば、例えば単列運転中の蓄電素子列が過放電したり逆に過充電となることを防止でき、システム保護が図れる。   Thereby, according to this Embodiment, it can prevent that the electrical storage element row | line | column in single row driving | running | working, for example, is over-discharged or reversely overcharged, and can protect a system.
