　二次電池等の蓄電装置を利用することで、エネルギーの有効活用がなされている。例えば、近年、環境に優しいクリーンエネルギーとして太陽光発電システムの開発が盛んに行なわれているが、太陽光を電力に変換する光電変換モジュールは蓄電機能を備えていないため、二次電池と組合わせて使用されることがある。例えば、光電変換モジュールにより発電された電力を一旦二次電池に充電して、外部負荷の要求等に応じて二次電池から放電する充放電制御によってエネルギーの有効活用が行なわれている。 Energy is effectively used by using power storage devices such as secondary batteries. For example, in recent years, photovoltaic power generation systems have been actively developed as environmentally friendly clean energy, but photoelectric conversion modules that convert sunlight into electric power do not have a storage function, so they can be combined with secondary batteries. May be used. For example, energy is effectively used by charge / discharge control in which electric power generated by a photoelectric conversion module is once charged in a secondary battery and discharged from the secondary battery in response to a request from an external load or the like.
　二次電池には、例えば、リチウムイオン二次電池を用いることができる。二次電池は、様々な環境等のもとで長期間使用されるため、様々な安全策が講じられることが望まれる。そこで、例えばリチウムイオン二次電池単体等においても様々な安全策が講じられているが、二次電池をラック等に収納して用いる場合に、さらに安全性を向上させることが好ましい。 As the secondary battery, for example, a lithium ion secondary battery can be used. Since secondary batteries are used for a long period of time under various environments, it is desirable that various safety measures be taken. Therefore, for example, various safety measures have been taken for a lithium ion secondary battery alone, but it is preferable to further improve safety when the secondary battery is housed in a rack or the like.
　例えば、特許文献１には、電源装置として、安全弁を備える複数の電池をケースに収納する電源装置であって、ケースを区画壁でもって、複数の電池を収納している電池室と、この電池室に収納される電池の安全弁から排出されるガスを排気する排気室とに区画している構成が開示されている。ここでは、消火剤または不活性流体を排気室に噴射する消火器と、排気室の内圧を検出する圧力センサとを備え、消火器を圧力センサで制御して、排気室の内圧が設定圧力よりも高くなると、消火器が排気室内に消火剤または不活性流体を噴射するようにしてなる構成が開示されている。 For example, Patent Document 1 discloses a power supply device that houses a plurality of batteries including a safety valve in a case as a power supply device, the battery chamber having a partition wall and a plurality of batteries, and the battery. A configuration is disclosed in which an exhaust chamber for exhausting gas discharged from a safety valve of a battery housed in the chamber is partitioned. Here, a fire extinguisher that injects a fire extinguisher or an inert fluid into the exhaust chamber and a pressure sensor that detects the internal pressure of the exhaust chamber are provided. The fire extinguisher is controlled by the pressure sensor so that the internal pressure of the exhaust chamber is greater than the set pressure. In other words, a configuration is disclosed in which the fire extinguisher injects a fire extinguisher or an inert fluid into the exhaust chamber.
特開２００７－２７０１１号公報JP 2007-27011 A
　ところで、特許文献１の構成によれば、ケース全体について排気室の内圧を監視して、消火器が作動することとしているので、例えば、１つの二次電池が異常になったとしても、排気室の内圧によっては消火器が作動しないこともあり得る。このように、異常監視だけでは、複数の二次電池の異常の対策としては不十分な場合があるので、さらに安全性を向上させることが好ましい。 By the way, according to the configuration of Patent Document 1, since the fire extinguisher is activated by monitoring the internal pressure of the exhaust chamber for the entire case, for example, even if one secondary battery becomes abnormal, the exhaust chamber Depending on the internal pressure, the fire extinguisher may not operate. As described above, it is preferable to further improve the safety because the abnormality monitoring alone may be insufficient as a countermeasure for the abnormality of the plurality of secondary batteries.
　また、二次電池等の蓄電装置を利用することで、エネルギーの有効活用がなされている例として上述した太陽光発電システムは、二次電池を備える二次電池ブロックのほかに、二次電池ブロックに対する充放電制御を行う充放電制御回路や、光電変換モジュールによって発電された直流電力を交流電力に変換して電力会社等の系統電力に供給するための電力変換を行うＤＣ／ＡＣ変換回路や、二次電池ブロックに対する充放電を遮断するための遮断回路といった種々の装置を構成要素とする回路ブロックが設けられる。そして、回路ブロックと二次電池ブロックを一括して二次電池収納システムラックに収納すると便利であるが、回路ブロックの各要素を作動させると熱が発生することがあるため、収納本体部の内部を適宜換気して放熱させることが望まれる。しかしながら、二次電池ブロックの万一の発火に対して消火剤による消火を行う際には、収納本体部が換気されたままの状態であると、消火剤が空気とともに収納本体部の外部に排出されることがあり、消火剤を好適に二次電池ブロックに供給することができない。 Further, as an example in which energy is effectively utilized by using a power storage device such as a secondary battery, the solar power generation system described above includes a secondary battery block in addition to a secondary battery block including a secondary battery. A charge / discharge control circuit that performs charge / discharge control on the battery, a DC / AC conversion circuit that performs power conversion to convert the DC power generated by the photoelectric conversion module into AC power and supply it to system power such as an electric power company, A circuit block including various devices such as a shut-off circuit for shutting off charging / discharging of the secondary battery block is provided. And it is convenient to store the circuit block and the secondary battery block together in the secondary battery storage system rack, but heat may be generated when each element of the circuit block is operated. It is desirable to ventilate and dissipate heat appropriately. However, when extinguishing with a fire extinguishing agent in the unlikely event of a secondary battery block fire, the fire extinguishing agent is discharged to the outside of the storage main body together with air if the storage main body is still ventilated. The fire extinguishing agent cannot be suitably supplied to the secondary battery block.
　本発明の目的は、複数の二次電池の１つに異常が発生した場合でも、その二次電池の異常発生に留めることを可能にする二次電池収納システムラックを提供することである。他の目的は、より好適に二次電池ブロックに対して消火剤を供給することができる二次電池収納システムラックを提供することである。 An object of the present invention is to provide a secondary battery storage system rack that makes it possible to keep an abnormality in a secondary battery even when an abnormality occurs in one of a plurality of secondary batteries.

It is preferable to be configured to be larger than the outflow amount of air in a region where the secondary battery block is disposed in the internal space of the storage main body when supplying the extinguishing agent.
　上記構成の少なくとも１つにより、二次電池収納システムラックは、収納本体部に回路ブロックと二次電池ブロックとを内部に収納し、二次電池ブロックは、隣接する二次電池の間に配置される板材を有するので、仮に１つの二次電池に発熱、発火等の異常が生じたとしても、板材によって隣接する二次電池は隔てられ、板材との間には空間的隙間があるので、異常が発生したその二次電池のみに、異常発生を留めることができる。 With at least one of the above configurations, the secondary battery storage system rack stores the circuit block and the secondary battery block in the storage main body, and the secondary battery block is disposed between the adjacent secondary batteries. Even if an abnormality such as heat generation or ignition occurs in one secondary battery, the adjacent secondary battery is separated by the plate material, and there is a spatial gap between the plate material.

Since there is a fire extinguishing device that has a fire resistant heat insulating material plate arranged and can inject a fire extinguishing agent toward the gap between the fire resistant heat insulating material plate of the secondary battery block and the secondary battery, tentatively to one secondary battery Even if an abnormality such as heat generation or ignition occurs, the abnormality can be stopped only in the secondary battery in which the abnormality has occurred.
　また、二次電池収納システムラックによれば、消火装置から二次電池ブロックに対して消火剤を供給する前の収納本体部の内部空間のうち回路ブロックが配置される領域の空気の流出量が、消火剤を供給する際の収納本体部の内部空間のうち二次電池ブロックが配置される領域の空気の流出量よりも多くなる。これにより、消火剤が空気とともに収納本体部の外部に排出されることを抑制することができるため、より好適に二次電池ブロックに対して消火剤を供給することができる。 Further, according to the secondary battery storage system rack, the outflow amount of air in the area where the circuit block is arranged in the internal space of the storage main body before supplying the fire extinguishing agent from the fire extinguishing device to the secondary battery block is reduced. More than the outflow amount of air in the region where the secondary battery block is arranged in the internal space of the storage main body when supplying the extinguishing agent.

　図４は、二次電池１４０と耐火断熱材板１３４の配置を示す詳細図である。図４の下段には、正面扉１４を開いた状態の収納本体部１２の下側部分の様子が示され、図４の上段には、正面扉１４を閉じた状態の収納本体部１２において１つの二次電池１４０の上方から下方を見た平面図が示されている。 FIG. 4 is a detailed view showing the arrangement of the secondary battery 140 and the refractory insulation board 134. The lower part of FIG. 4 shows the state of the lower part of the storage main body 12 with the front door 14 open, and the upper part of FIG. 4 shows 1 in the storage main body 12 with the front door 14 closed. The top view which looked at the downward direction from the upper direction of the two secondary batteries 140 is shown.
　支柱１２２，１２４，１２６，１２８は、収納本体部１２の内部の４隅にそれぞれ１本ずつ立てられ、収納本体部１２の底面にしっかりと固定されている柱材である。支柱１２２，１２４，１２６，１２８は、二次電池ブロック１２０を構成する要素と回路ブロック４０を配置する取付柱としての機能を有する。支柱１２２，１２４，１２６，１２８は、必要に応じ、収納本体部１２の天井部まで延ばして、柱材としての固定性を向上させることができる。かかる柱材１２２，１２４，１２６，１２８は、耐火性と適当な強度を有する材料を柱形状に成形したもの、例えば、金属製の柱、パイプ等を用いることができる。図４の例では角柱が用いられているが、多角形柱、円柱等であってもよい。 The pillars 122, 124, 126, and 128 are column members that are respectively set up at four corners inside the storage body 12 and are firmly fixed to the bottom surface of the storage body 12. The support columns 122, 124, 126, and 128 have a function as mounting columns for arranging the elements constituting the secondary battery block 120 and the circuit block 40. The support columns 122, 124, 126, and 128 can be extended to the ceiling portion of the storage main body portion 12 as necessary to improve the fixing property as a pillar material. As the column members 122, 124, 126, and 128, a material having fire resistance and appropriate strength formed into a column shape, for example, a metal column, a pipe, or the like can be used. In the example of FIG. 4, a prism is used, but a polygonal column, a cylinder, or the like may be used.
　棚受材１３０，１３２は、向かい合う２本の柱材に差し渡されて、その上に棚板を置いたときにそれを支持する機能を有する棒材である。図４の例では、支柱１２２と支柱１２６の間に棚受材１３０が差し渡されて固定され、支柱１２４と支柱１２８の間に棚受材１３２が差し渡されて固定される。この１対の棚受材１３０，１３２の高さ位置を同じとすることで、この一対の棚受材１３０，１３２の間に、後述する耐火断熱材板１３４を棚板としてこれを水平に配置できる。 The shelf support members 130 and 132 are bar members that have a function of supporting a shelf board when placed on two pillar members facing each other and placing a shelf board thereon. In the example of FIG. 4, the shelf support member 130 is passed and fixed between the support column 122 and the support column 126, and the shelf support material 132 is passed and fixed between the support column 124 and the support column 128. By making the height positions of the pair of shelf receiving materials 130 and 132 the same, the fireproof heat insulating plate 134 described later is placed horizontally between the pair of shelf receiving materials 130 and 132 as a shelf plate. it can.
　棚受材１３０，１３２は、支柱１２２，１２４，１２６，１２８の高さ方向に沿って、予め定めた間隔で取り付けられる。予め定めた間隔は、二次電池１４０の直方体の高さに比べて十分大きな寸法の間隔として設定される。かかる棚板材１３０，１３２は、耐火性を有する材料で構成された棒材を用いることができる。例えば、金属丸棒を用いることができる。 The shelf receiving materials 130 and 132 are attached at predetermined intervals along the height direction of the columns 122, 124, 126, and 128. The predetermined interval is set as an interval having a dimension sufficiently larger than the height of the rectangular parallelepiped of the secondary battery 140. As the shelf boards 130 and 132, a bar made of a fire-resistant material can be used. For example, a metal round bar can be used.
　これによって、収納本体部１２の内部の二次電池ブロック１２０において、上下方向に予め定められた間隔で、複数の棚板を配置することができる。図４の下段の図では、３対の棚受材１３０，１３２が図示されている。 Thereby, in the secondary battery block 120 inside the storage main body 12, a plurality of shelf boards can be arranged at predetermined intervals in the vertical direction. In the lower diagram of FIG. 4, three pairs of shelf support members 130 and 132 are illustrated.
　耐火断熱材板１３４は、棚受材１３０，１３２を用いて、その上に配置される棚板である。図４の上段に示されるように、耐火断熱材板１３４は、収納本体部１２の内部の空間面積から、側壁部材側に適当な空間を残して、その他の部分を覆うのに十分な大きさを有する。適当な空間とは、図３に関連して説明した信号線１１２、電力線１１４、消火剤供給配管２８を通し、また、吸気弁９４と排気弁９６が作動したときの吸気と排気を行うのに十分な余裕空間のことである。例えば、側壁部材側から数ｃｍの隙間をあけて、この隙間空間を上記の適当な空間とすることができる。 The fireproof heat insulating material board 134 is a shelf board arrange | positioned on it using the shelf receiving materials 130 and 132. FIG. As shown in the upper part of FIG. 4, the refractory heat insulating material plate 134 is large enough to cover the other part from the space area inside the storage body 12 while leaving an appropriate space on the side wall member side. Have Appropriate space is used for the intake and exhaust when the intake valve 94 and the exhaust valve 96 are operated through the signal line 112, the power line 114, and the fire extinguisher supply pipe 28 described with reference to FIG. It is enough room. For example, a gap of several centimeters is formed from the side wall member side, and this gap space can be set as the appropriate space.
　耐火断熱材板１３４は、具体的には、平面形状が矩形形状の４隅を切り欠いた形状を有する。４隅の切り欠きは、支柱１２２，１２４，１２６，１２８を通すために設けられるものである。矩形形状の大きさは、二次電池１４０の直方体の平面寸法よりも十分大きく設定される。例えば、二次電池１４０の直方体の平面寸法を約４５ｃｍ×約４５ｃｍとし、上記の例で、収納本体部１２の底面寸法を約７０ｃｍ×約７０ｃｍとして、側壁部材の厚さを数ｍｍとし、上記の余裕空間を数ｃｍとするときは、耐火断熱材板１３４の矩形形状寸法を約６０ｃｍ×約６０ｃｍ程度とすることができる。勿論、これ以外の寸法とすることもできる。 Specifically, the fire-resistant heat insulating material plate 134 has a shape in which the planar shape is a rectangular shape with four corners cut out. The cutouts at the four corners are provided to pass through the columns 122, 124, 126, and 128. The size of the rectangular shape is set sufficiently larger than the planar dimension of the rectangular parallelepiped of the secondary battery 140. For example, the planar size of the rectangular parallelepiped of the secondary battery 140 is about 45 cm × about 45 cm, and in the above example, the bottom surface size of the storage main body 12 is about 70 cm × about 70 cm, the thickness of the side wall member is several mm, When the marginal space is several centimeters, the rectangular shape of the refractory insulation board 134 can be about 60 cm × about 60 cm. Of course, other dimensions can be used.
　耐火断熱材板１３４には、上記のように、耐火性・断熱効果・強度に優れているケイ酸カルシウム板を、上記の形状に成形または加工したものを用いることができる。耐火断熱材板１３４は、耐火性、断熱性、適当な強度を有することが必要であるので、上記のように、板厚方向には加工孔等の不必要な開口部を有しない平板である。なお、ケイ酸カルシウム板の強度を補強するために、断熱性を損なわない程度に、適当な厚さの金属薄板等を用いて積層構造としてもよい。 As the refractory heat insulating material plate 134, as described above, a calcium silicate plate excellent in fire resistance, heat insulating effect and strength can be formed or processed into the above shape. Since the fireproof heat insulating material plate 134 needs to have fire resistance, heat insulating properties, and appropriate strength, as described above, it is a flat plate that does not have unnecessary openings such as processed holes in the plate thickness direction. . In addition, in order to reinforce the strength of the calcium silicate plate, a laminated structure may be used by using a metal thin plate having an appropriate thickness to the extent that the heat insulation is not impaired.
　上記のように、棚受材１３０，１３２は、上下方向に予め定められた間隔で配置されるので、耐火断熱材板１３４も、収納本体部１２の内部の二次電池ブロック１２０において、上下方向に予め定められた間隔で、複数枚配置できる。これによって、収納本体部１２の内部の二次電池ブロック１２０を、上下を耐火断熱材板１３４で仕切られた複数の空間に区分できる。なお、図４では、耐火断熱材板１３４が収納本体部１２の底面にも１枚敷かれている例が示されているが、例えば、底面側に信号線、回路部品等が配置される場合には、このようにすることが好ましい。 As described above, since the shelf support members 130 and 132 are arranged at predetermined intervals in the vertical direction, the refractory heat insulating material plate 134 is also arranged in the vertical direction in the secondary battery block 120 inside the storage body 12. A plurality of sheets can be arranged at predetermined intervals. As a result, the secondary battery block 120 inside the storage main body 12 can be divided into a plurality of spaces partitioned vertically by the refractory heat insulating material plate 134. FIG. 4 shows an example in which one sheet of the fireproof heat insulating material board 134 is also laid on the bottom surface of the storage main body 12. For example, when signal lines, circuit components, etc. are arranged on the bottom surface side. It is preferable to do this.
　二次電池１４０は、耐火断熱材板１３４によって上下を仕切られて区分された空間に１つずつ配置されるリチウムイオン組電池である。１つずつとは、制御ユニット４４によって制御できる１つの単位を示し、例えば、ブレーカユニット４２によって他の二次電池１４０と区別して遮断できる単位である。図３の例では、６つの二次電池１４０が、耐火断熱材板１３４によって上下を仕切られて区分された空間に１つずつ配置されているが、この６つの二次電池１４０は、それぞれが１つずつ独立的に、ブレーカユニット４２によって充放電状態を遮断できるようにされている。 The secondary battery 140 is a lithium ion assembled battery that is arranged one by one in a space partitioned by an upper and lower sides by a fireproof heat insulating material plate 134. “One by one” means one unit that can be controlled by the control unit 44, for example, a unit that can be distinguished from other secondary batteries 140 by the breaker unit 42. In the example of FIG. 3, six secondary batteries 140 are arranged one by one in a space partitioned by the refractory heat insulating material plate 134, and each of the six secondary batteries 140 includes The charge / discharge state can be interrupted by the breaker unit 42 one by one.
　支持部材１３６，１３８は、二次電池１４０を耐火断熱材板１３４から空間的に離間して隙間を介して配置されるように、頂面である電池支持面と、耐火断熱材板１３４との離間のための脚部とを有するＬ字形状の折り曲げ板部材である。支持部材１３６は、Ｌ字形状の頂面である電池支持面を水平になるように脚部が支柱１２２，１２６に取り付けられ、支持部材１３８は、電池支持面を水平になるように脚部が支柱１２４，１２８に取り付けられる。取付に際しては、支持部材１３６の電池支持面の高さ位置と支持部材１３８の電池支持面の高さ位置が同じとなるように設定される。これにより、一対の支持部材１３６，１３８のそれぞれの電池支持面によって、二次電池１４０の底面側を支持することができる。 The support members 136 and 138 are arranged between the battery support surface that is the top surface and the fireproof heat insulating material plate 134 so that the secondary battery 140 is spatially spaced from the fireproof heat insulating material plate 134 and disposed through a gap. It is an L-shaped bending board member which has a leg part for separation. The support member 136 has legs attached to the columns 122 and 126 so that the battery support surface, which is an L-shaped top surface, is horizontal, and the support member 138 has legs so that the battery support surface is horizontal. Attached to the columns 124 and 128. At the time of attachment, the height position of the battery support surface of the support member 136 and the height position of the battery support surface of the support member 138 are set to be the same. Accordingly, the bottom surface side of the secondary battery 140 can be supported by the battery support surfaces of the pair of support members 136 and 138.
　支持部材１３６，１３８の支柱１２２，１２４，１２６，１２８に対する取付位置は、その電池支持面に二次電池１４０を置いて支持したときに、二次電池１４０の上面と、その上方に配置される耐火断熱材板１３４の下面との間に適当な上方側空間的隙間が形成されるように、また、二次電池１４０の下面と、その下方に配置される耐火断熱材板１３４の上面との間に適当な下方側空間的隙間が形成されるように設定される。これにより、二次電池１４０は、その上下に配置される耐火断熱材板１３４に対し、空間的に離間しているように配置される。この空間的な離間によって、二次電池１４０の周囲の空気の流通をよくし、隣接する二次電池１４０の間の熱伝導が小さくなると共に、後述する消化剤の導入が容易になる。 The mounting positions of the support members 136 and 138 with respect to the columns 122, 124, 126, and 128 are arranged above and above the secondary battery 140 when the secondary battery 140 is placed and supported on the battery support surface. The upper surface of the secondary battery 140 and the upper surface of the refractory heat insulating material plate 134 disposed below the secondary battery 140 are formed so that an appropriate upper spatial gap is formed between the lower surface of the refractory heat insulating material plate 134. An appropriate lower spatial gap is formed between them. Thereby, the secondary battery 140 is arrange | positioned so that it may space apart with respect to the refractory heat insulation board | plate 134 arrange | positioned at the upper and lower sides. This spatial separation improves the circulation of air around the secondary battery 140, reduces the heat conduction between the adjacent secondary batteries 140, and facilitates the introduction of a digestive agent to be described later.
　このように、二次電池１４０は、上方側空間的隙間と下方側空間的隙間によって、耐火断熱材板１３４を含め、他の要素と離隔しており、空気の熱伝導率は固体に比べ小さいので、１つの二次電池１４０に発熱が生じても、他の二次電池１４０に対する熱伝導を効果的に抑制することができる。 Thus, the secondary battery 140 is separated from other elements including the refractory heat insulating material plate 134 by the upper spatial gap and the lower spatial gap, and the thermal conductivity of air is smaller than that of the solid. Therefore, even if heat is generated in one secondary battery 140, heat conduction to the other secondary batteries 140 can be effectively suppressed.
　また、二次電池１４０は、耐火断熱材板１３４によって上下を仕切られて区分された空間に１つずつ配置されているので、仮に１つの二次電池１４０が発火しても、耐火断熱材板１３４によって、他の二次電池１４０にその影響が及ぶことを効果的に抑制できる。 In addition, since the secondary batteries 140 are arranged one by one in the space partitioned by the fireproof heat insulating material plate 134, even if one secondary battery 140 is ignited, the fireproof heat insulating material plate 134 can effectively suppress other secondary batteries 140 from being affected.
　このように、耐火断熱材板１３４によって上下を仕切られて区分された空間に、二次電池１４０を１つずつ、耐火断熱材板１３４から空間的に離間して配置することで、複数の二次電池１４０の１つに発熱異常が発生した場合でも、その二次電池１４０の発熱異常に留めて、熱の伝播による他の二次電池１４０の発熱異常の発生を抑制することができる。また、１つの二次電池１４０に発熱異常が発生すると、二次電池温度センサによってその異常が検出され、信号線１１２によって制御ユニット４４にその異常が伝送されるので、制御ユニット４４は、その異常の生じた二次電池１４０の充放電をブレーカユニット４２によって遮断することができる。これによって、その異常の生じた二次電池１４０から他の二次電池１４０へ異常が伝播することを食い止めることができる。もっとも場合によっては、異常発生の際に、全部の二次電池１４０の充放電を遮断するものとしてもよい。 In this manner, a plurality of two secondary batteries 140 are spatially separated from the refractory heat insulating material plate 134 in the space partitioned by the refractory heat insulating material plate 134 and separated from each other. Even when a heat generation abnormality occurs in one of the secondary batteries 140, the heat generation abnormality of the secondary battery 140 can be suppressed by suppressing the heat generation abnormality of the secondary battery 140. In addition, when a heat generation abnormality occurs in one secondary battery 140, the abnormality is detected by the secondary battery temperature sensor, and the abnormality is transmitted to the control unit 44 by the signal line 112. The breaker unit 42 can block the charging / discharging of the secondary battery 140 that has occurred. As a result, it is possible to prevent the abnormality from propagating from the secondary battery 140 in which the abnormality has occurred to another secondary battery 140. However, depending on the case, when an abnormality occurs, charging / discharging of all the secondary batteries 140 may be cut off.
　次に、熱伝導の抑制、充放電の遮断にもかかわらず、仮に、１つの二次電池１４０に発火が生じた場合でも、耐火断熱材板１３４の耐火性によって、その二次電池１４０の発火に留めて、他の二次電池１４０へ発火が進展することを抑制することができる。 Next, even if one secondary battery 140 ignites despite suppression of heat conduction and interruption of charge / discharge, the ignition of the secondary battery 140 is caused by the fire resistance of the refractory insulation board 134. However, it is possible to suppress the ignition from progressing to the other secondary battery 140.
　このように１つの二次電池１４０に発火が生じたときは、上記の耐火断熱材板１３４の作用、ブレーカユニット４２の作用に加えて、消火装置２０を作動させて、二次電池ブロック１２０に消火剤を供給し、迅速に消火を行うことができる。消火装置２０の作動は、外部警報信号によって行われることもできるが、二次電池１４０の温度である二次電池温度の異常、第１煙センサ９０あるいは第２煙センサ９２による煙の検出に基いて制御ユニット４４が消火装置２０の消火剤供給弁２６を開弁させることで行われる。 When one secondary battery 140 is ignited in this way, in addition to the action of the fireproof heat insulating plate 134 and the action of the breaker unit 42, the fire extinguishing device 20 is operated to Fire extinguishing agent can be supplied to quickly extinguish the fire. The operation of the fire extinguishing device 20 can be performed by an external alarm signal, but is based on the abnormality of the secondary battery temperature, which is the temperature of the secondary battery 140, or the detection of smoke by the first smoke sensor 90 or the second smoke sensor 92. Then, the control unit 44 opens the fire extinguisher supply valve 26 of the fire extinguishing device 20.

Hereinafter, the fire-extinguishing agent injection port 150 provided in the secondary battery block 120 will be described.
　噴射口１５０は、上記のように、消火装置２０の消火剤タンク２４から消火剤供給弁２６を経由して二次電池ブロック１２０に向かって延びる消火剤供給配管２８に設けられるノズルである。そして、制御ユニット４４の制御の下で消火剤供給弁２６が作動したときに、消火剤タンク２４から消化剤供給配管２８に供給される消化剤を二次電池ブロック１２０の中に噴射する機能を有する。 The injection port 150 is a nozzle provided in the fire extinguishing agent supply pipe 28 extending toward the secondary battery block 120 from the fire extinguishing agent tank 24 of the fire extinguishing device 20 via the fire extinguishing agent supply valve 26 as described above. And when the fire extinguisher supply valve 26 is operated under the control of the control unit 44, the function of injecting the digestive agent supplied from the fire extinguisher tank 24 to the digestive agent supply pipe 28 into the secondary battery block 120 is provided. Have.
　噴射口１５０は、耐火断熱材板１３４によって上下を仕切られて区分された空間ごとに１つずつ配置される。すなわち、耐火断熱材板１３４によって上下を仕切られて区分された空間に配置される二次電池１４０ごとに１つずつ配置される。もっとも、噴射口１５０を１つの二次電池１４０に対し、複数設けるものとしてもよい。例えば、消火剤供給配管２８を複数設け、１つの二次電池１４０に対する噴射口１５０を、各消化剤供給配管２８ごとに１つずつ設けるものとできる。 The injection port 150 is arranged one by one for each space partitioned by the fireproof heat insulating material plate 134. That is, one battery is disposed for each secondary battery 140 disposed in a space partitioned by the refractory heat insulating material plate 134. However, a plurality of injection ports 150 may be provided for one secondary battery 140. For example, a plurality of extinguishing agent supply pipes 28 may be provided, and one injection port 150 for one secondary battery 140 may be provided for each digestive agent supply pipe 28.
　噴射口１５０の配置位置は、二次電池ブロック１２０の耐火断熱材板１３４と二次電池１４０との間の隙間に向かって、二次電池１４０の側面側から消火剤を噴射できるように設定される。 The arrangement position of the injection port 150 is set so that the fire extinguishing agent can be injected from the side surface side of the secondary battery 140 toward the gap between the fireproof heat insulating material plate 134 of the secondary battery block 120 and the secondary battery 140. The
　噴射口１５０の具体的な高さ位置は、消火剤の単位体積当りの質量を考慮して設定される。ここで、消火剤は、消火剤タンク２４に充填される物質で、噴射時の単位体積当りの質量が空気の単位体積当りの質量よりも大きく、電気的絶縁性を有するものが用いられる。具体的には、噴射後に熱分解によって揮発性のトリフルオロメチル基（ＣＦ3 *）を発生するＣＦ3ＣＦ2Ｃ（Ｏ）ＣＦ（ＣＦ3)2を用いることができる。例えば、消火装置２０として株式会社コーアツ製の商品名レモラを用い、消火剤として、レモラに充填される消火剤型式番号ＦＫ－５－１－１２、商標登録Ｎｏｖｅｃ１２３０を用いることができる。 The specific height position of the injection port 150 is set in consideration of the mass per unit volume of the extinguishing agent. Here, the extinguishing agent is a substance that fills the extinguishing agent tank 24, and has a mass per unit volume at the time of injection larger than a mass per unit volume of air and has electrical insulation. Specifically, CF 3 CF 2 C (O) CF (CF 3 ) 2 that generates a volatile trifluoromethyl group (CF 3 * ) by thermal decomposition after injection can be used. For example, the product name Remora manufactured by Koatsu Co., Ltd. can be used as the fire extinguishing device 20, and the fire extinguishing agent model number FK-5-1-12 and trademark registration Novec 1230 filled in the remora can be used as the fire extinguishing agent.
　このＮｏｖｅｃ１２３０は、消火剤タンク２４に充填されているときは、その単位体積あたりの質量が空気の単位体積当りの質量より大きい電気絶縁性の液体状態である。そして、空気中への噴射によってその単位体積当りの質量が空気の単位体積当りの質量より大きいので、下方に向かって移動し、発火している対象物である二次電池１４０に触れることで熱分解し、揮発性のトリフルオロメチル基（ＣＦ3 *）を発生する。このトルフルオロメチル基（ＣＦ3 *）が、燃焼の過程で燃料物質から発生する活性な遊離基であるＯＨ*、Ｈ*と反応し、この遊離基を比較的不活性なＨ2分子またはＨ2Ｏ分子に変えることで、燃焼時の活性な遊離基であるＯＨ*、Ｈ*の連鎖的発生を抑制する作用を有する。 The Novec 1230 is in an electrically insulating liquid state in which the mass per unit volume is larger than the mass per unit volume of air when the fire extinguisher tank 24 is filled. Since the mass per unit volume is larger than the mass per unit volume of air due to the injection into the air, it moves downward and touches the secondary battery 140, which is the object to be ignited, to generate heat. Decomposes to generate volatile trifluoromethyl groups (CF 3 * ). This trifluoromethyl group (CF 3 * ) reacts with OH * and H * , which are active free radicals generated from the fuel material in the course of combustion, and this free radical is converted into a relatively inert H 2 molecule or H By changing to 2 O molecules, it has the effect of suppressing chain generation of OH * and H * which are active free radicals during combustion.
　噴射口１５０の具体的な高さ位置は、上記の消火剤の噴射時の単位体積当りの質量が空気の単位体積当りの質量より大きいことを考慮し、二次電池１４０の上面と、その上方に配置される耐火断熱材板１３４の下面との間の上方側空間的隙間に対応するように設定される。さらに具体的には、二次電池１４０の上面位置よりも高い位置であって、その二次電池１４０の上方に配置される耐火断熱材板１３４の下面よりも低い高さ位置に設定される。 Considering that the mass per unit volume at the time of injection of the above-mentioned extinguishing agent is larger than the mass per unit volume of air, the specific height position of the injection port 150 is the upper surface of the secondary battery 140 and above It is set so as to correspond to the upper side spatial gap between the lower surface of the refractory heat insulating material plate 134 arranged in the above. More specifically, the position is set higher than the upper surface position of the secondary battery 140 and lower than the lower surface of the refractory heat insulating material plate 134 disposed above the secondary battery 140.
　その様子を図５に示す。図５の下段、上段の内容は図４と同様である。噴射口１５０は、耐火断熱材板１３４によって上下を仕切られて区分された空間ごとに１つずつ配置され、その高さ位置は、その区分空間に配置される二次電池１４０の上面の高さ位置より少し高い位置に設定される。少し高い位置とは、噴射口１５０から噴射した消火剤が、その単位体積あたりの質量が空気の単位体積当りの質量より大きい性質によって二次電池１４０の上面に噴霧される際に、二次電池１４０の上面の全体を覆うことができるような位置である。この高さ位置は、消化剤の噴射口１５０からの噴射速度、噴射口１５０から二次電池１４０までの距離等によって設定することができる。 This is shown in FIG. The contents of the lower and upper stages in FIG. 5 are the same as those in FIG. The injection port 150 is arranged one by one for each space partitioned by the fireproof heat insulating material plate 134, and the height position thereof is the height of the upper surface of the secondary battery 140 disposed in the partitioned space. The position is set slightly higher than the position. The slightly higher position means that when the extinguishing agent injected from the injection port 150 is sprayed on the upper surface of the secondary battery 140 due to the property that the mass per unit volume is larger than the mass per unit volume of air. The position is such that the entire upper surface of 140 can be covered. This height position can be set by the jetting speed of the digestive agent from the injection port 150, the distance from the injection port 150 to the secondary battery 140, and the like.
　噴射口１５０から噴射された消火剤１５２は、図５に示されるように、噴射口１５０からその単位体積当りの質量が空気の単位体積当りの質量より大きい性質のため、下方に向かって下降しながら噴霧される。そして、二次電池１４０の上面に到達して、その温度によって熱分解し、揮発し、気化し、収納本体部１２の左側の隙間空間に向かって流れる。 As shown in FIG. 5, the extinguishing agent 152 injected from the injection port 150 descends downward from the injection port 150 because the mass per unit volume is larger than the mass per unit volume of air. Sprayed while. Then, it reaches the upper surface of the secondary battery 140 and thermally decomposes, volatilizes and vaporizes depending on the temperature, and flows toward the gap space on the left side of the storage main body 12.
　なお、発火した二次電池１４０が１つであっても、消火剤１５２は、全ての噴射口１５０から噴射され、全ての二次電池１４０に対し、消火が行われる。これは、二次電池１４０の発火が特別な異常状態であるため、発火した二次電池１４０に対してのみの消火を行ったのでは手遅れになる可能性があるためである。もっとも、噴射口１５０にそれぞれ開口制御装置を付加し、制御ユニット４４の制御の下でその開口制御を行うものとして、消火が必要な二次電池１４０のみを消火するものとしてもよい。 Even if there is only one secondary battery 140 that has ignited, the fire extinguishing agent 152 is injected from all the injection ports 150, and all the secondary batteries 140 are extinguished. This is because the ignition of the secondary battery 140 is in a special abnormal state, and it may be too late to extinguish only the secondary battery 140 that has ignited. However, it is also possible to add only an opening control device to each of the injection ports 150 and perform the opening control under the control of the control unit 44, so that only the secondary battery 140 that needs to be extinguished is extinguished.
　消火の際には、上記のように、制御ユニット４４の機能により、吸気ファン部３２、排気ファン部３０の動作が停止され、収納本体部１２が密閉状態とされる。そして、消火後には、吸気弁９４と排気弁９６とが開弁され、吸気弁９４から空気を収納本体部１２に内部に導入し、収納本体部１２の内部の消火済みの揮発気体を空気とともに排気弁９６から排気装置によって外部に排出することが行われる。 When the fire is extinguished, the operation of the intake fan unit 32 and the exhaust fan unit 30 is stopped by the function of the control unit 44 as described above, and the storage main body unit 12 is sealed. After the fire is extinguished, the intake valve 94 and the exhaust valve 96 are opened, air is introduced from the intake valve 94 into the storage main body 12, and the extinguished volatile gas inside the storage main body 12 is combined with the air. The exhaust valve 96 is discharged to the outside by an exhaust device.
　なお、上記では、消化剤の単位体積当りの質量を空気の単位体積当りの質量より大きいものとして説明したが、逆に消化剤の単位体積当りの質量が空気の単位体積当りの質量より小さいときは、それに応じて噴射口の高さ位置を変更する。この場合の具体的な高さ位置としては、二次電池１４０の下面と、その下方に配置される耐火断熱材板１３４の上面との間の下方側空間的隙間に対応するように設定することがよい。さらに具体的には、二次電池１４０の下面位置よりも低い位置であって、その二次電池１４０の下方に配置される耐火断熱材板１３４の上面よりも高い高さ位置に設定することがよい。 In the above description, the mass per unit volume of the digestive agent is assumed to be larger than the mass per unit volume of air. Conversely, when the mass per unit volume of the digestive agent is smaller than the mass per unit volume of air. Changes the height position of the injection port accordingly. The specific height position in this case is set so as to correspond to the lower spatial gap between the lower surface of the secondary battery 140 and the upper surface of the refractory heat insulating material plate 134 disposed below the secondary battery 140. Is good. More specifically, it may be set at a position lower than the lower surface position of the secondary battery 140 and higher than the upper surface of the refractory heat insulating material plate 134 disposed below the secondary battery 140. Good.

　ここで、図６～８に示されるように、収納本体部１２の内部に配置される要素の配置関係は、質量の大きい二次電池ブロック１２０を回路ブロック４０よりも重力方向Ｇの下方に配置する。換言すれば、二次電池ブロック１２０に比べて質量の小さい回路ブロック４０を、二次電池ブロック１２０よりも重力方向Ｇの上方に配置する。このように、二次電池ブロック１２０を収納本体部１２の内部において最も下方に配置することで、収納本体部１２における重心が下部に位置するため、収納本体部１２を安定して設置することができる。なお、収納本体部１２の重心が下部となるように二次電池ブロック１２０を下方に配置すればよく、二次電池ブロック１２０の下方に他の装置が設けられていてもよい。 Here, as shown in FIGS. 6 to 8, the arrangement relationship of the elements arranged inside the storage main body 12 is that the secondary battery block 120 having a large mass is arranged below the circuit block 40 in the gravity direction G.

　ブレーカユニット４２よりも下方に配置される二次電池ブロック１２０は、充放電を行う複数の二次電池１４０と、各二次電池１４０の間における熱伝導を抑制するための耐火断熱板材１３４とを含んで構成される。二次電池１４０として、例えば、炭素物質で構成された負極と、リチウムイオンが移動するための電解液と、リチウムイオンを可逆的に出し入れできる正極活物質とを有するリチウムイオン二次電池を用いることができる。耐火断熱板材１３４としては、例えば、耐火性・断熱効果・強度に優れているケイ酸カルシウム板を用いることができる。なお、二次電池ブロック１２０は、複数の二次電池１４０と耐火断熱板材１３４とを含むものとして説明したが、耐火断熱板材１３４を含まずに二次電池１４０のみを含むものとしてもよい。 The secondary battery block 120 disposed below the breaker unit 42 includes a plurality of secondary batteries 140 that perform charging and discharging, and a refractory heat insulating plate 134 for suppressing heat conduction between the secondary batteries 140.

Although the secondary battery block 120 has been described as including a plurality of secondary batteries 140 and the refractory heat insulating plate material 134, the secondary battery block 120 may include only the secondary battery 140 without including the refractory heat insulating plate material 134.
　また、各二次電池１４０は、ブレーカユニット４２と電力線１１４を介して接続される電極と、内部の温度状態を検知する温度センサ１４２とを含んで構成される。そして、当該温度センサ１４２は、それぞれ信号線１１２によって制御ユニット４４に接続され、制御ユニット４４にそれぞれの温度信号（温度情報）を伝送している。 Each secondary battery 140 includes an electrode connected to the breaker unit 42 via the power line 114, and a temperature sensor 142 that detects an internal temperature state.

Stop supplying the extinguishing agent to the machine. The fire extinguisher supply valve 26 is controlled to be opened and closed by the fire extinguisher control unit 22.
　消火剤コントロールユニット２２は、外部警報信号線１０４を介して入力される消火開始信号を示す外部警報信号、あるいは、制御ユニット４４からの消火開始信号があったときに消火剤供給弁２６を開弁する。また、消火剤コントロールユニット２２は、制御ユニット４４からの消火終了信号があったときに、消火剤供給弁２６を閉弁する。 The fire extinguisher control unit 22 opens the fire extinguisher supply valve 26 when an external alarm signal indicating a fire extinguishing start signal input via the external alarm signal line 104 or a fire extinguishing start signal from the control unit 44 is received. To do. The fire extinguisher control unit 22 closes the fire extinguisher supply valve 26 when a fire extinguishing end signal is received from the control unit 44.
　吸気弁９４と排気弁９６は、収納本体部１２の天井部に取り付けられ、二次電池ブロック１２０に異常が生じ、消火装置２０が作動した後で、消火後の使用済み消火剤を図示しない外部の吸引ポンプによって吸引排気させるために用いられる開閉弁である。吸気弁９４と排気弁９６の動作は、回路ブロック４０の制御ユニット４４の下で制御される。具体的には、通常時には吸気弁９４も排気弁９６も閉弁とされ、消火後に、吸気弁９４が開弁されて空気に対し開放され、排気弁９６が開弁されて図示しない吸引ポンプに接続される。これによって、吸気弁９４から収納本体部１２の内部に空気が取り込まれ、空気と共に使用済み消火剤が排気弁９６を介して吸引ポンプによって外部に排出される。 The intake valve 94 and the exhaust valve 96 are attached to the ceiling of the storage main body 12, and after the fire extinguishing device 20 is activated after the secondary battery block 120 is abnormal, the used fire extinguisher after the extinguishing is not illustrated. It is an on-off valve used for suctioning and exhausting by a suction pump. The operation of the intake valve 94 and the exhaust valve 96 is controlled under the control unit 44 of the circuit block 40. Specifically, the intake valve 94 and the exhaust valve 96 are normally closed at the normal time, and after the fire is extinguished, the intake valve 94 is opened and released to the air, and the exhaust valve 96 is opened and the suction pump is not shown. Connected. As a result, air is taken into the storage main body 12 from the intake valve 94, and the used extinguishing agent together with the air is discharged to the outside through the exhaust valve 96 by the suction pump.
　避圧弁９８は、収納本体部１２の内部圧力が予め定められた所定の圧力値を超えたときに、開弁して収納本体部１２の圧力値を正常化する弁である。 The pressure-reducing valve 98 is a valve that opens to normalize the pressure value of the storage body 12 when the internal pressure of the storage body 12 exceeds a predetermined pressure value.
　続いて、二次電池収納システムラック１０の制御ユニット４４の消火制御部８２の動作について、図６～図９を用いて説明する。図９は、二次電池収納システムラック１０において、二次電池ブロック１２０が万一発火した場合に消火する手順を示すタイミングチャートである。図９において、複数の二次電池１４０のうち、異常をきたした二次電池１４０の温度変化をＢＴＡ（Ｂａｔｔｅｒｙ　Ｔｅｍｐｅｒａｔｕｒｅ　Ａｂｎｏｒｍａｌ）として示している。また、図９において、異常をきたした二次電池１４０の近傍に配置されているが、正常状態を保ったままの二次電池１４０の温度変化をＢＴＡと比較するためにＢＴＮ（Ｂａｔｔｅｒｙ　Ｔｅｍｐｅｒａｔｕｒｅ　Ｎｏｒｍａｌ）として示している。ここで、Ｔ0は、充放電停止用閾値温度を示し、Ｔ1は、Ｔ0よりも高い温度である異常信号発生用閾値温度を示し、Ｔ2は、Ｔ1よりもさらに高い温度である消火用閾値温度を示している。なお、以下では二次電池ブロック１２０の各二次電池１４０のうち、１つの二次電池１４０のみが異常状態（ＢＴＡ）と変化するが、その他の二次電池１４０は正常状態（ＢＴＮ）のままであるものとして説明する。 Next, the operation of the fire extinguishing control unit 82 of the control unit 44 of the secondary battery storage system rack 10 will be described with reference to FIGS. FIG. 9 is a timing chart showing a procedure for extinguishing a fire when the secondary battery block 120 is ignited in the secondary battery storage system rack 10. In FIG. 9, the temperature change of the secondary battery 140 in which the abnormality occurs among the plurality of secondary batteries 140 is shown as BTA (Battery Temperature Abnormal). Further, in FIG. 9, BTN (Battery Temperature Normal) is arranged in the vicinity of the secondary battery 140 in which an abnormality has occurred, in order to compare the temperature change of the secondary battery 140 while maintaining a normal state with BTA. As shown. Here, T 0 indicates a charge / discharge stop threshold temperature, T 1 indicates an abnormal signal generation threshold temperature that is higher than T 0 , and T 2 is a temperature higher than T 1. The threshold temperature for fire extinguishing is shown. In the following, among the secondary batteries 140 of the secondary battery block 120, only one secondary battery 140 changes to an abnormal state (BTA), but the other secondary batteries 140 remain in a normal state (BTN). It is assumed that
　図９に示されるように、二次電池ブロック１２０の各二次電池１４０のうち異常をきたした二次電池１４０の温度変化を示すＢＴＡは、時刻ｔ1のときに充放電停止用閾値温度Ｔ0よりも高くなる。このとき、消火制御部８２は、信号線１１２によって伝送されてくる温度信号のうち少なくとも１つが異常状態であると判断する。そして、消火制御部８２は、少なくとも１つの二次電池ブロック１２０に異常が発生している可能性があるとして、ブレーカユニット４２を遮断制御することで二次電池ブロック１２０に対する充放電制御を停止する。なお、複数の二次電池１４０が異常温度へと変化する場合には、最も早い時刻に充放電停止用閾値温度Ｔ0に到達した時刻に、ブレーカユニット４２を遮断制御する。 As shown in FIG. 9, the BTA indicating the temperature change of the secondary battery 140 that has malfunctioned among the secondary batteries 140 of the secondary battery block 120 is the threshold temperature T for charging / discharging stop at time t 1. Higher than 0 . At this time, the fire extinguishing control unit 82 determines that at least one of the temperature signals transmitted through the signal line 112 is in an abnormal state. And the fire extinguishing control part 82 stops charging / discharging control with respect to the secondary battery block 120 by carrying out cutoff control of the breaker unit 42 supposing that the abnormality may have generate | occur | produced in the at least 1 secondary battery block 120. . When the plurality of secondary batteries 140 change to an abnormal temperature, the breaker unit 42 is controlled to be cut off at the time when the charge / discharge stop threshold temperature T 0 is reached at the earliest time.
　その後、ＢＴＡは、一旦上昇した温度が下降し、時刻ｔ2のときに再び充放電停止用閾値温度Ｔ0よりも低くなる。このとき、消火制御部８２は、二次電池ブロック１２０に異常が発生している可能性がなくなったものとして、ブレーカユニット４２を接続制御することで二次電池ブロック１２０に対する充放電制御を再開する。このように、充放電停止用閾値温度Ｔ0を一旦上回った後に、再び充放電停止用閾値温度Ｔ0を下回る場合に充放電制御を再開するのは、二次電池ブロック１２０が許容温度範囲内の正常状態であるにもかかわらず、何らかの原因で一時的に温度が上昇してしまい、誤って異常状態であるとして処理してしまうことに対する対策が必要であるからである。なお、複数の二次電池１４０が異常温度へと変化する場合には、全ての温度が充放電停止用閾値温度Ｔ0よりも低くなった時刻に、二次電池ブロック１２０に対する充放電制御を再開する。 After that, the temperature of the BTA that has once increased decreases and becomes lower than the threshold temperature T 0 for stopping charging / discharging again at time t 2 . At this time, the fire extinguishing control unit 82 resumes the charge / discharge control for the secondary battery block 120 by controlling the connection of the breaker unit 42, assuming that there is no possibility of abnormality in the secondary battery block 120. . As described above, the charge / discharge control is resumed when the charge / discharge stop threshold temperature T 0 is once again lower than the charge / discharge stop threshold temperature T 0 after the temperature exceeds the charge / discharge stop threshold temperature T 0 once. This is because it is necessary to take measures against the fact that the temperature temporarily rises for some reason and is erroneously processed as being in an abnormal state in spite of the normal state. When a plurality of secondary batteries 140 change to an abnormal temperature, the charge / discharge control for the secondary battery block 120 is resumed at the time when all the temperatures are lower than the charge / discharge stop threshold temperature T 0. To do.
　次に、図９に示されるように、ＢＴＡは、時刻ｔ3のときに、再び、充放電停止用閾値温度Ｔ0よりも高くなる。このとき、消火制御部８２は、二次電池ブロック１２０に異常が発生している可能性があるとして、再び、ブレーカユニット４２を遮断制御することで二次電池ブロック１２０に対する充放電制御を停止する。その後、ＢＴＡは、時刻ｔ4のときに異常信号発生用閾値温Ｔ1よりも高くなる。このときは、充放電停止用閾値温度Ｔ0の場合と異なり、二次電池ブロック１２０に何らかの異常があるものとして、二次電池ブロック１２０に異常が発生していることを示す異常信号を、異常信号線１０６を介して外部に出力する。なお、複数の二次電池１４０が異常温度へと変化する場合には、最も早い時刻に異常信号発生用閾値温Ｔ1に到達した時刻に、異常信号を出力する。 Next, as shown in FIG. 9, BTA again becomes higher than the charge / discharge stop threshold temperature T 0 at time t 3 . At this time, the fire extinguishing control unit 82 stops charging / discharging control for the secondary battery block 120 by controlling the breaker unit 42 again, assuming that the secondary battery block 120 may be abnormal. . Thereafter, the BTA becomes higher than the abnormal signal generation threshold temperature T 1 at time t 4 . At this time, unlike the case of the charge / discharge stop threshold temperature T 0 , it is assumed that there is some abnormality in the secondary battery block 120 and an abnormal signal indicating that an abnormality has occurred in the secondary battery block 120 is abnormal. Output to the outside via the signal line 106. When a plurality of secondary batteries 140 change to an abnormal temperature, an abnormal signal is output at the time when the abnormal signal generation threshold temperature T 1 is reached at the earliest time.
　ところで、図９に示されるように、時刻ｔ5のときに、第１煙センサ９０あるいは第２煙センサ９２の少なくともいずれか１つが二次電池ブロック１２０の発火により発生した煙を検知したとしてＬｏｗ信号からＨｉｇｈ信号へと変化している。このとき、消火制御部８２は、吸気ファン部３２のファンを停止するとともに、吸気側シャッタ１８２によって吸気ファン部３２の吸気口を閉塞するように吸気側シャッタ１８２をスライドさせる。さらに、消火制御部８２は、排気ファン部３０のファンを停止するとともに、排気側シャッタ１８０によって排気ファン部３０の排気口を閉塞するように排気側シャッタ１８０をスライドさせる。それらが行われた後で、消火制御部８２は、消火剤コントロールユニット２２に対して消火開始信号を出力する。なお、第１煙センサ９０及び第２煙センサ９２が煙を検知しない場合であってもＢＴＡの温度が時刻ｔ6において消火用閾値温度Ｔ2を上回るため、消火制御部８２は、上記と同様の処理を行う。なお、複数の二次電池１４０が異常温度へと変化する場合には、最も早い時刻に消火用閾値温度Ｔ2に到達した時刻に、消火開始信号を出力する。 Incidentally, as shown in FIG. 9, it is assumed that at time t 5 , at least one of the first smoke sensor 90 and the second smoke sensor 92 detects smoke generated by the ignition of the secondary battery block 120. The signal changes from a high signal to a high signal. At this time, the fire extinguishing control unit 82 stops the fan of the intake fan unit 32 and slides the intake side shutter 182 so that the intake side shutter 182 closes the intake port of the intake fan unit 32. Further, the fire extinguishing control unit 82 stops the fan of the exhaust fan unit 30 and slides the exhaust side shutter 180 so that the exhaust side shutter 180 closes the exhaust port of the exhaust fan unit 30. After these operations are performed, the fire extinguishing control unit 82 outputs a fire extinguishing start signal to the fire extinguisher control unit 22. Even if the first smoke sensor 90 and the second smoke sensor 92 do not detect smoke, the BTA temperature exceeds the fire extinguishing threshold temperature T 2 at time t 6 , so the fire extinguishing control unit 82 is the same as above. Perform the process. When the plurality of secondary batteries 140 change to an abnormal temperature, a fire extinguishing start signal is output at the time when the fire extinguishing threshold temperature T 2 is reached at the earliest time.
　その後、消火制御部８２は、消火装置２０による消火が開始されて十分な時間が経過したと考えられる時刻ｔ9において、消火剤コントロールユニット２２に対して消火終了信号を出力する。 Thereafter, the fire extinguishing control unit 82 outputs a fire extinguishing end signal to the fire extinguisher control unit 22 at a time t 9 when it is considered that a sufficient time has elapsed since the start of extinguishing by the fire extinguishing device 20.
　二次電池ブロック１２０に対する消火を終えた後、ＢＴＡの温度が下降し充放電停止用閾値温度Ｔ0を下回る時刻ｔ10において、消火制御部８２は、使用済みの消火剤を排出するために、吸気弁９４と排気弁９６を開弁し、吸気弁９４が空気に対し開放され、排気弁９６は図示しない吸引ポンプに接続される。これによって、吸気弁９４から収納本体部１２の内部に空気が取り込まれ、空気と共に使用済み消火剤が排気弁９６を介して吸引ポンプによって外部に排出される。なお、複数の二次電池１４０が異常温度へと変化する場合には、全ての温度が充放電停止用閾値温度Ｔ0よりも低くなった時刻に、使用済み消火剤の排気を行う。 After finishing the extinguishing of the secondary battery block 120, at time t 10 the temperature of the BTA is below the threshold temperature T 0 for charging and discharging stop descends, fire extinguishing control unit 82, for discharging the spent extinguishing agent, The intake valve 94 and the exhaust valve 96 are opened, the intake valve 94 is opened to the air, and the exhaust valve 96 is connected to a suction pump (not shown). As a result, air is taken into the storage main body 12 from the intake valve 94, and the used extinguishing agent together with the air is discharged to the outside through the exhaust valve 96 by the suction pump. When the plurality of secondary batteries 140 change to an abnormal temperature, the used extinguishing agent is exhausted at a time when all the temperatures are lower than the charging / discharging stop threshold temperature T 0 .
　上記のように、二次電池収納システムラック１０によれば、消火装置２０から二次電池ブロック１２０に対して消火剤を供給するときに、吸気ファン部３２のファンを停止して吸気口を吸気側シャッタ１８２で閉塞させ、排気ファン部３０のファンを停止して排気口を排気側シャッタ１８０で閉塞させる。これにより、消火装置２０から二次電池ブロック１２０に対して消火剤を供給する前は、外部から、回路ブロック４０が配置される領域を含む収納本体部１２の内部空間に対して空気が十分取り込まれているが、消火装置２０から二次電池ブロック１２０に対して消火剤を供給する際に、外部から、二次電池ブロック１２０が配置される領域を含む収納本体部１２の内部空間に対して空気が取り込まれなくなる。換言すれば、消火剤を供給する前の回路ブロック４０が配置される領域の空気の流出量は、消火剤を供給する際の二次電池ブロック１２０が配置される領域の空気の流出量よりも多くなる。このように、二次電池ブロック１２０が収納される収納本体部１２の内部空間を密閉し、二次電池ブロック１２０が配置される領域と収納本体部１２の外部との間の空気の流れを止めることで、消火剤が空気とともに収納本体部１２の外部に排出されることを防止することができるため、より好適に二次電池ブロック１２０に対して消火剤を供給することができる。 As described above, according to the secondary battery storage system rack 10, when the fire extinguisher is supplied from the fire extinguishing device 20 to the secondary battery block 120, the fan of the intake fan unit 32 is stopped to suck the intake port. The side shutter 182 is closed, the fan of the exhaust fan unit 30 is stopped, and the exhaust port is closed by the exhaust side shutter 180. Thereby, before supplying the fire extinguishing agent from the fire extinguishing device 20 to the secondary battery block 120, air is sufficiently taken in from the outside into the internal space of the storage body 12 including the area where the circuit block 40 is disposed. However, when supplying a fire extinguishing agent from the fire extinguishing device 20 to the secondary battery block 120, the external space with respect to the internal space of the storage main body 12 including the region where the secondary battery block 120 is disposed. Air is not taken in. In other words, the amount of air outflow in the region where the circuit block 40 before the extinguishing agent is disposed is larger than the amount of air outflow in the region where the secondary battery block 120 is disposed when supplying the extinguishing agent. Become more. In this manner, the internal space of the storage main body 12 in which the secondary battery block 120 is stored is sealed, and the flow of air between the region where the secondary battery block 120 is disposed and the outside of the storage main body 12 is stopped. As a result, it is possible to prevent the extinguishing agent from being discharged to the outside of the storage main body 12 together with the air, and thus it is possible to more suitably supply the extinguishing agent to the secondary battery block 120.
　次に、二次電池収納システムラック１０の変形例である二次電池収納システムラック１１について説明する。図１０は、正面扉１４を開いているときの二次電池収納システムラック１１の具体的な要素の配置関係を示す図である。二次電池収納システムラック１１と二次電池収納システムラック１０の相違点は、吸気ファン部３２、排気ファン部３０、吸気側シャッタ１８２、排気側シャッタ１８０の代わりに複数の換気口１８６が設けられている点と、吸気通路１７０と、排気通路１７２と、区画壁１７７とが設けられている点であるためその相違点を中心に説明する。 Next, a secondary battery storage system rack 11 that is a modification of the secondary battery storage system rack 10 will be described. FIG. 10 is a diagram showing the arrangement relationship of specific elements of the secondary battery storage system rack 11 when the front door 14 is opened. The difference between the secondary battery storage system rack 11 and the secondary battery storage system rack 10 is that a plurality of ventilation openings 186 are provided instead of the intake fan unit 32, the exhaust fan unit 30, the intake side shutter 182, and the exhaust side shutter 180. Therefore, the difference will be mainly described because the intake passage 170, the exhaust passage 172, and the partition wall 177 are provided.
　区画壁１７７は、収納本体部１２の内部空間を重力方向Ｇのほぼ真ん中において２つの領域に区画するための部材である。２つの領域のうち、一方の領域は回路ブロック４０を配置するための領域である回路ブロック配置側領域１７８であり、他方の領域は二次電池ブロック１２０を配置するための領域である二次電池ブロック配置側領域１７９である。ここで、第１煙センサ９０は、二次電池ブロック配置側領域１７９の上部に設けられることとなり、第２煙センサ９２は、回路ブロック配置側領域１７８の上部に設けられることとなる。 The partition wall 177 is a member for partitioning the internal space of the storage main body 12 into two regions in the middle of the gravity direction G. Of the two areas, one area is a circuit block arrangement side area 178 that is an area for arranging the circuit block 40, and the other area is a secondary battery that is an area for arranging the secondary battery block 120. This is a block arrangement side area 179. Here, the first smoke sensor 90 is provided in the upper part of the secondary battery block arrangement side region 179, and the second smoke sensor 92 is provided in the upper part of the circuit block arrangement side region 178.
　吸気通路１７０は、一方側が吸気弁９４と接続され、他方側が区画壁１７７を貫通して二次電池ブロック配置側領域１７９に接続される配管である。排気通路１７２は、一方側が排気弁９６と避圧弁９８とに接続され、他方側が区画壁１７７を貫通して二次電池ブロック配置側領域１７９に接続される配管である。なお、消火剤タンク２４から二次電池ブロック１２０に対して消火剤を供給するための消火剤供給配管２８も区画壁１７７を貫通して延伸し、その先端部分に設けられる噴射口１５０がそれぞれ各二次電池１４０に向けられるように配置される。 The intake passage 170 is a pipe having one side connected to the intake valve 94 and the other side passing through the partition wall 177 and connected to the secondary battery block arrangement side region 179. The exhaust passage 172 is a pipe having one side connected to the exhaust valve 96 and the pressure-reducing valve 98 and the other side passing through the partition wall 177 and connected to the secondary battery block arrangement side region 179. The extinguishing agent supply pipe 28 for supplying the extinguishing agent from the extinguishing agent tank 24 to the secondary battery block 120 also extends through the partition wall 177, and each of the injection ports 150 provided at the front end portion thereof has an injection port 150. Arranged to face the secondary battery 140.
　複数の換気口１８６は、正面扉１４のうち、回路ブロック配置側領域１７８が設けられる領域に対応する部分に設けられる開口である。これにより、回路ブロック４０の各要素が作動することによって発生する熱を収納本体部１２の外部に放熱することができる。 The plurality of ventilation openings 186 are openings provided in a portion of the front door 14 corresponding to an area where the circuit block arrangement side area 178 is provided. Thereby, the heat generated by the operation of each element of the circuit block 40 can be radiated to the outside of the storage main body 12.
　ここで、複数の換気口１８６は、図１０においても示されるように、回路ブロック配置側領域１７８が設けられる領域に対応する部分に設けられるが、二次電池ブロック配置側領域１７９に対応する領域には設けられていない。つまり、収納本体部１２の内部空間のうち、二次電池ブロック配置側領域１７９は密閉状態となっている。このように、二次電池収納システムラック１１では、外部から、収納本体部１２の内部空間のうちの回路ブロック配置側領域１７８には、空気が十分取り込まれているが、外部から、収納本体部１２の内部空間のうちの二次電池ブロック配置側領域１７９には、空気が取り込まれていない。換言すれば、消火剤を供給する前の回路ブロック配置側領域１７８の空気の流出量は、消火剤を供給する際の二次電池ブロック配置側領域１７９の空気の流出量よりも多くなる。したがって、消火剤が空気とともに収納本体部１２の外部に排出されることを防止することができるため、より好適に二次電池ブロック１２０に対して消火剤を供給することができる。 Here, as shown in FIG. 10, the plurality of ventilation openings 186 are provided in a portion corresponding to the region where the circuit block arrangement side region 178 is provided, but the region corresponding to the secondary battery block arrangement side region 179. Is not provided. That is, in the internal space of the storage main body 12, the secondary battery block arrangement side region 179 is in a sealed state. As described above, in the secondary battery storage system rack 11, air is sufficiently taken into the circuit block arrangement side region 178 in the internal space of the storage main body 12 from the outside. Air is not taken into the secondary battery block arrangement side region 179 in the 12 internal spaces. In other words, the outflow amount of air in the circuit block arrangement side region 178 before supplying the extinguishing agent is larger than the outflow amount of air in the secondary battery block arrangement side region 179 when supplying the extinguishing agent. Therefore, since it can prevent that a fire extinguisher is discharged | emitted outside the storage main-body part 12 with air, a fire extinguisher can be supplied with respect to the secondary battery block 120 more suitably.
