Description

本発明は、ケースに電池を内蔵する電源装置に関し、とくに電池の安全弁が開弁する状態における安全性を向上できる電源装置に関する。   The present invention relates to a power supply device that incorporates a battery in a case, and more particularly to a power supply device that can improve safety in a state where a safety valve of the battery is opened.

電池をケースに収納している車両用等に使用される電源装置は、電池が異常な状態で充放電されるときに、電池に設けた安全弁を開弁する。安全弁は、ガスや電解液を排出して、外装缶の破裂を防止する。電池から排出されるガスは、電池の種類により異なり、たとえばリチウムイオン二次電池は、開弁された安全弁から酸素を含むガスを排出する。また、ニッケル水素電池は、水素を含むガスを排出する。安全弁が開いて、ケース内にガスが噴射される状態は、電池が異常な状態で使用されることから、電池温度も異常に高温に過熱されることがある。ケース内に充満するガスと、電池の過熱は電源装置の安全性を低下させる。とくに、異常な状態では電池温度が数百度に上昇して、火災の原因となることもある。   A power supply device used for a vehicle or the like in which a battery is housed in a case opens a safety valve provided on the battery when the battery is charged and discharged in an abnormal state. The safety valve discharges gas and electrolyte and prevents the outer can from bursting. The gas discharged from the battery differs depending on the type of the battery. For example, a lithium ion secondary battery discharges oxygen-containing gas from the opened safety valve. The nickel metal hydride battery discharges a gas containing hydrogen. Since the battery is used in an abnormal state when the safety valve is opened and gas is injected into the case, the battery temperature may be abnormally overheated. The gas that fills the case and the overheating of the battery reduce the safety of the power supply. In particular, in an abnormal state, the battery temperature may rise to several hundred degrees, which may cause a fire.

電池の過熱による危険な状態を解消するために、密閉されたケース内に不活性ガス等の不活性な物質を充填する電源装置が開発されている。（特許文献１参照）
また、ケース内の異常発熱を防止するために、ケース内に不活性ガス発生物質や消火器を内蔵する電源装置が開発されている。（特許文献２及び３参照）
特開平１０−５５８２２号公報 特開２００１−３３２２３７号公報 特開平１０−２４７５２７号公報 In order to eliminate a dangerous state due to overheating of a battery, a power supply device has been developed that fills an enclosed case with an inert substance such as an inert gas. (See Patent Document 1)
In addition, in order to prevent abnormal heat generation in the case, a power supply device incorporating an inert gas generating substance and a fire extinguisher in the case has been developed. (See Patent Documents 2 and 3)
JP-A-10-55822 JP 2001-332237 A Japanese Patent Laid-Open No. 10-247527

特許文献１の公報には、複数の電池をケースに収納すると共に、このケース内に窒素、ヘリウム、アルゴン、ネオン、クリプトン、キセノン、二酸化炭素等の不活性ガス、あるいは不燃性の非水溶媒、あるいは、液状またはゲル状または固形状の高分子を満たして、かつ、ケースを密閉している電源装置が記載される。この構造の電源装置は、電池が異常な状態となってケース内にガスが噴射されても、電池の周囲を不活性な物質で囲んでいるので、電源装置が危険な状態となるのを緩和できる特長がある。   In the publication of Patent Document 1, a plurality of batteries are housed in a case, and an inert gas such as nitrogen, helium, argon, neon, krypton, xenon, carbon dioxide, or a nonflammable non-aqueous solvent is contained in the case. Alternatively, a power supply device that fills a liquid, gel, or solid polymer and seals the case is described. With this structure, even if the battery is in an abnormal state and gas is injected into the case, the battery is surrounded by an inactive substance, reducing the danger of the power supply becoming dangerous There is a feature that can be.

さらに、特許文献２に記載される電源装置は、複数の電池をケースに収納すると共に、このケース内に熱分解で不活性ガスを発生させる物質を収納している。この電源装置は、ケースに収納している電池が異常発熱すると、不活性ガス発生物質が熱分解されてケース内に不活性ガスを発生させる。したがって、電池が過熱されるときに、電池の周囲に不活性ガスを満たして、電源装置が危険な状態となるのを緩和できる。   Furthermore, the power supply device described in Patent Document 2 houses a plurality of batteries in a case and a substance that generates an inert gas by thermal decomposition in the case. In this power supply device, when a battery stored in the case abnormally generates heat, the inert gas generating substance is thermally decomposed to generate an inert gas in the case. Therefore, when the battery is overheated, it is possible to alleviate the danger of the power supply device being filled with an inert gas around the battery.

しかしながら、これらの電源装置は、異常電池から排出されるガスがケース内に満たされるので、排出されたガスが異常発熱している電池の周囲に存在する環境となることに変わりはない。このように、電池から排出される酸素や水素を含むガスが、電池を収納しているケース内に充満される状態は、電池温度が数百度に上昇する極めて異常な状態を考えると、決して好ましい状態ではない。
また、特許文献２の電源装置においては、不活性ガス発生物質の熱分解が始まる温度や反応速度等の設定が難しく、電池の異常発熱時に、最適なタイミングで不活性ガスを発生させるのが極めて難しい問題点もある。 However, in these power supply devices, since the gas discharged from the abnormal battery is filled in the case, there is no change in the environment where the discharged gas exists around the battery that is abnormally heated. Thus, the state in which the gas containing oxygen and hydrogen discharged from the battery is filled in the case containing the battery is never preferable in view of the extremely abnormal state in which the battery temperature rises to several hundred degrees. It is not a state.
Further, in the power supply device of Patent Document 2, it is difficult to set the temperature and reaction rate at which thermal decomposition of the inert gas generating substance starts, and it is extremely difficult to generate the inert gas at the optimal timing when the battery is abnormally heated. There are also difficult problems.

本発明は、このような欠点を解決することを目的に開発されたものである。本発明の第１の目的は、電池が異常な状態となってケース内にガスが噴射される場合においても、過熱された電池から受ける影響を極減して安全性を向上できる電源装置を提供することにある。   The present invention has been developed for the purpose of solving such drawbacks. A first object of the present invention is to provide a power supply device that can improve safety by minimizing the influence of an overheated battery even when the battery is in an abnormal state and gas is injected into the case. There is to do.

さらにまた、特許文献３に記載される電源装置は、ケースに収納している電池が異常発熱し、ケース内の温度が許容値を超えた場合、消火器等の異常発熱低減手段の起動操作手段であるレバーを押し下げて、二酸化炭素のガス圧で炭酸水素ナトリウムを主成分とする粉末を筐体内に放出させる。炭酸水素ナトリウムは高温に加熱されると吸熱して、二酸化炭素と水蒸気を発生し、筐体内の温度を下げるとともに、不活性雰囲気に保ち、火災の発生を防止したり、燃焼反応を終了させる。   Furthermore, in the power supply device described in Patent Document 3, when the battery housed in the case abnormally heats up and the temperature in the case exceeds an allowable value, the starting operation means of the abnormal heat reduction means such as a fire extinguisher Is pressed down, and the powder containing sodium hydrogen carbonate as a main component is discharged into the casing by the gas pressure of carbon dioxide. When sodium bicarbonate is heated to a high temperature, it absorbs heat, generating carbon dioxide and water vapor, lowering the temperature in the casing, keeping it in an inert atmosphere, preventing the occurrence of fire, and terminating the combustion reaction.

この装置は、消火器等の異常発熱低減手段を手動で作動させ、あるいは、温度センサー、煙センサー、ガスセンサー、炎センサー等で作動させる。非水電解液電池は、異常発熱するとき、初期の段階では電池の表面温度の上昇、次の段階では安全弁の作動による非水電解液や発生ガスの電池からの放出が起こり、最終段階では発火現象が起こり、火災の発生まで至ることになる。   This apparatus manually operates abnormal heat generation reducing means such as a fire extinguisher, or is operated by a temperature sensor, a smoke sensor, a gas sensor, a flame sensor, or the like. When a non-aqueous electrolyte battery heats up abnormally, the battery surface temperature rises in the initial stage, and the non-aqueous electrolyte or generated gas is released from the battery by the operation of the safety valve in the next stage. Phenomenon occurs, and it leads to fire outbreak.

消火器を手動で動作させる装置は、ユーザーが最適なタイミングで消火剤を噴射するのが難しい。とくに、車両に使用される電源装置のように、使用されるユーザー層の範囲が広い場合、全てのユーザーが最適なタイミングで消火器を動作できない。また、温度センサー、煙センサー、ガスセンサー、炎センサー等で消火器を動作させる装置も、簡単な検出では理想的なタイミングで消火剤を噴射できない。たとえば、温度センサーで消火器を動作させる場合、全ての電池温度を検出して、いずれかの電池温度が設定温度よりも高くなるときに、消火器を動作させる必要がある。この機構は、たとえば１００個以上の電池をケースに収納する車両用の電源装置等においては、各々の電池温度を温度センサーで検出する必要があるので、電池温度の検出回路が極めて複雑になる。特定の電池温度を検出して消火器を動作させる場合、温度が検出されない電池の温度が異常状態となるときに、正確なタイミングで消火器を動作できない。また、煙センサーやガスセンサーで消火器を動作させる装置は、センサーの配置部分によって、常に正しく消火器を正確なタイミングで動作できない。それは、センサーを配置する部分に煙やガスが流れるときには正確に検出できても、センサーを配置しない部分の煙やガスを検出できないからである。また、炎センサーで消火器を動作させる装置は、火炎を検出した後に消火器を動作させるので、タイミングが遅れる欠点がある。   A device that manually operates a fire extinguisher is difficult for a user to inject a fire extinguishing agent at an optimal timing. In particular, when the range of user groups used is wide, such as a power supply device used in a vehicle, all users cannot operate the fire extinguisher at an optimal timing. In addition, a device that operates a fire extinguisher with a temperature sensor, a smoke sensor, a gas sensor, a flame sensor, etc. cannot inject a fire extinguisher at an ideal timing with simple detection. For example, when operating a fire extinguisher with a temperature sensor, it is necessary to detect all battery temperatures and to operate the fire extinguisher when any battery temperature is higher than a set temperature. In this mechanism, for example, in a power supply device for a vehicle in which 100 or more batteries are housed in a case, each battery temperature needs to be detected by a temperature sensor, so that the battery temperature detection circuit becomes extremely complicated. When operating a fire extinguisher by detecting a specific battery temperature, the fire extinguisher cannot be operated at an accurate timing when the temperature of a battery whose temperature is not detected becomes an abnormal state. Moreover, the device which operates a fire extinguisher with a smoke sensor or a gas sensor cannot always operate the fire extinguisher correctly at an accurate timing due to the arrangement part of the sensor. This is because even if smoke or gas flows through the part where the sensor is arranged, it can be detected accurately, but the smoke or gas where the sensor is not arranged cannot be detected. Moreover, since the apparatus which operates a fire extinguisher with a flame sensor operates a fire extinguisher after detecting a flame, there is a disadvantage that timing is delayed.

本発明は、さらにこの欠点を解決することを目的に開発されたものである。本発明の第２の目的は、簡単な構造で電池異常を正確に速やかに検出して消火器を動作でき、消火器からケース内に効果的に消火剤を噴射できる電源装置を提供することにある。   The present invention has been developed for the purpose of solving this drawback. A second object of the present invention is to provide a power supply apparatus that can detect a battery abnormality accurately and promptly with a simple structure and operate a fire extinguisher, and can effectively inject a fire extinguisher into the case. is there.

本発明の電源装置は、前述の目的を達成するために以下の構成を備える。
電源装置は、安全弁１０を備える複数の電池１をケース２に収納している。ケース２は、区画壁３でもって、複数の電池１を収納している電池室４と、この電池室４に収納される電池１の安全弁１０から排出されるガスを排気する排気室５とに区画している。電池室４に配設される複数の電池１は、安全弁１０の開口部１１を排気室５に連通するように配設している。電源装置は、電池１の安全弁１０が開弁されて、安全弁１０から排出されるガスを、電池室４に流入させることなく排気室５に流入させて、排気室５からケース２外に排出する。 The power supply apparatus of the present invention has the following configuration in order to achieve the above-described object.
The power supply device houses a plurality of batteries 1 including a safety valve 10 in a case 2. The case 2 includes a partition wall 3, a battery chamber 4 that houses a plurality of batteries 1, and an exhaust chamber 5 that exhausts gas discharged from the safety valve 10 of the battery 1 housed in the battery chamber 4. It is partitioned. The plurality of batteries 1 disposed in the battery chamber 4 are disposed so that the opening 11 of the safety valve 10 communicates with the exhaust chamber 5. In the power supply device, the safety valve 10 of the battery 1 is opened, and the gas discharged from the safety valve 10 flows into the exhaust chamber 5 without flowing into the battery chamber 4 and is discharged out of the case 2 from the exhaust chamber 5. .

本発明の電源装置は、排気室５を密閉構造として、排気室５に不活性流体を充填することができる。不活性流体は、不活性ガスあるいは不活性液体とすることができる。   The power supply device of the present invention can fill the exhaust chamber 5 with an inert fluid by using the exhaust chamber 5 as a sealed structure. The inert fluid can be an inert gas or an inert liquid.

本発明の電源装置は、排気室５を密閉構造とすると共に、排気室５に排出口１８を開口して、この排出口１８に排出弁１９を連結することができる。排出弁１９は、排気室５の内圧が設定圧力になると開弁して、排気室５内のガスを排気することができる。   The power supply device of the present invention can have the exhaust chamber 5 in a sealed structure, and can open an exhaust port 18 in the exhaust chamber 5 and connect the exhaust valve 19 to the exhaust port 18. The exhaust valve 19 is opened when the internal pressure of the exhaust chamber 5 reaches the set pressure, and the gas in the exhaust chamber 5 can be exhausted.

本発明の電源装置は、消火剤または不活性流体を排気室５に噴射する消火器２０を備えることができる。
ただし、本明細書は、消火器を、火災を消火するものに限定しない。本明細書において、消火器とは、消火剤または不活性流体を噴射して、発火や引火を防止し、あるいは、異常な高温となるのを防止する広い意味で使用する。 The power supply apparatus of the present invention can include a fire extinguisher 20 that injects a fire extinguisher or an inert fluid into the exhaust chamber 5.
However, this specification does not limit a fire extinguisher to what extinguishes a fire. In this specification, a fire extinguisher is used in a broad sense to prevent fire or ignition by injecting a fire extinguishing agent or an inert fluid, or preventing an abnormally high temperature.

さらに、本発明の電源装置は、排気室５を密閉構造とすると共に、排気室５の内圧を検出する圧力センサー２４を備えて、消火器２０を圧力センサー２４で制御することができる。この電源装置は、排気室５の内圧が設定圧力よりも高くなると、消火器２０が排気室５内に消火剤または不活性流体を噴射する。さらにまた、本発明の電源装置は、電池１が安全弁１０の開弁を検出する開弁センサー２６を備えて、電池１に設けている開弁センサー２６で消火器２０を制御することができる。この電源装置は、電池１の安全弁１０が開弁すると、消火器２０が排気室５に消火剤または不活性流体を噴射する。不活性流体は、不活性ガスあるいは不活性液体とすることができる。   Furthermore, the power supply device of the present invention has the exhaust chamber 5 having a sealed structure, and includes a pressure sensor 24 that detects the internal pressure of the exhaust chamber 5, and the fire extinguisher 20 can be controlled by the pressure sensor 24. In this power supply device, when the internal pressure of the exhaust chamber 5 becomes higher than the set pressure, the fire extinguisher 20 injects a fire extinguisher or an inert fluid into the exhaust chamber 5. Furthermore, the power supply apparatus according to the present invention includes the valve opening sensor 26 that detects the opening of the safety valve 10 by the battery 1, and can control the fire extinguisher 20 by the valve opening sensor 26 provided in the battery 1. In this power supply device, when the safety valve 10 of the battery 1 is opened, the fire extinguisher 20 injects a fire extinguisher or an inert fluid into the exhaust chamber 5. The inert fluid can be an inert gas or an inert liquid.

本発明の電源装置は、区画壁３に電池端部を挿入する貫通部を開口して、この貫通部に安全弁１０の開口部１１を有する電池端部を気密に挿入して、安全弁１０の開口部１１を排気室５に連通することができる。   The power supply device according to the present invention opens a through-hole into which the battery end is inserted into the partition wall 3, and the battery end having the opening 11 of the safety valve 10 is inserted into the through-hole in an airtight manner. The part 11 can communicate with the exhaust chamber 5.

本発明の電源装置は、ケース２内に回路基板２８を内蔵すると共に、この回路基板２８をポッティングして、絶縁樹脂２７に埋設することができる。さらに、本発明の電源装置は、電池室４をケース２の上部に、排気室５をケース２の下部に配置すると共に、電池室４に収納される複数の電池１は、安全弁１０の開口部１１を下向きとして排気室５に連通し、電池室４の上部に回路基板２８を配設して、回路基板２８と電池上部とをポッティングして絶縁樹脂２７に埋設することができる。さらに、本発明の電源装置は、電池１を非水系二次電池とすることができる。   The power supply device of the present invention can incorporate the circuit board 28 in the case 2 and can be embedded in the insulating resin 27 by potting the circuit board 28. Furthermore, the power supply device of the present invention has the battery chamber 4 at the upper part of the case 2 and the exhaust chamber 5 at the lower part of the case 2, and the plurality of batteries 1 housed in the battery chamber 4 are provided in the openings of the safety valve 10. 11 is directed downward and communicates with the exhaust chamber 5, and a circuit board 28 is disposed above the battery chamber 4, and the circuit board 28 and the upper part of the battery can be potted and embedded in the insulating resin 27. Furthermore, in the power supply device of the present invention, the battery 1 can be a non-aqueous secondary battery.

本発明の電源装置は、電池が異常な状態となってケース内にガスが噴射される場合においても、過熱された電池から受ける影響を極減して安全性を向上できる特長がある。それは、本発明の電源装置が、複数の電池を収納しているケースを、区画壁でもって、電池を収納している電池室と、電池から排出されるガスを排気する排気室とに区画すると共に、電池室に配設される電池の安全弁の開口部を排気室に連通させており、電池の安全弁から排出されるガスを、電池室に流入させることなく排気室に流入させて、排気室からケース外に排出するからである。この構造の電源装置は、異常電池から排出されるガスを電池室に流入させないので、排出されたガスが異常発熱している電池の周囲に充満されるのを確実に阻止でき、過熱された電池から受ける影響を極減して安全性を向上できる。   The power supply device of the present invention has an advantage that safety can be improved by minimizing the influence of the overheated battery even when the battery is in an abnormal state and gas is injected into the case. That is, the power supply device of the present invention partitions a case storing a plurality of batteries into a battery chamber storing a battery and an exhaust chamber exhausting gas discharged from the battery, with a partition wall. In addition, the opening of the safety valve of the battery disposed in the battery chamber communicates with the exhaust chamber, and the gas discharged from the safety valve of the battery flows into the exhaust chamber without flowing into the battery chamber. It is because it discharges from the case outside. The power supply device with this structure does not allow the gas discharged from the abnormal battery to flow into the battery chamber, so that the discharged gas can be reliably prevented from filling around the abnormally heated battery, and the overheated battery Safety can be improved by minimizing the effects of

さらに、本発明の請求項６の電源装置は、簡単な構造で電池異常を正確に速やかに検出して消火器を動作でき、消火器からケース内に効果的に消火剤を噴射できる特長がある。それは、この電源装置が、排気室を密閉構造とすると共に、排気室の内圧を検出する圧力センサーで消火器を制御して、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いるからである。この電源装置は、排気室内の圧力で電池の異常を検出して消火器を動作させるので、従来の温度センサーや煙センサー、ガスセンサー、炎センサー等のセンサーで電池の異常を検出する装置のように、センサーの配置位置によって消火器の動作タイミングがずれることがなく、電池異常が発生して、電池の安全弁からガスが排出されると、このことを確実に検出できる特徴がある。また、消火器からは密閉構造の排気室内に消火剤または不活性流体を噴射するので、消火剤や不活性流体を有効に作用させて、効果的に消火できる特徴も実現する。   Furthermore, the power supply device according to claim 6 of the present invention has a feature that it can operate a fire extinguisher by detecting a battery abnormality accurately and promptly with a simple structure, and can effectively inject a fire extinguisher into the case. . This power supply device has a sealed structure in the exhaust chamber and controls the fire extinguisher with a pressure sensor that detects the internal pressure of the exhaust chamber. When the internal pressure of the exhaust chamber becomes higher than the set pressure, the fire extinguisher is This is because a fire extinguisher or an inert fluid is sprayed on. This power supply device detects battery abnormality with the pressure in the exhaust chamber and operates the fire extinguisher, so it seems like a conventional device that detects battery abnormality with sensors such as temperature sensor, smoke sensor, gas sensor, flame sensor, etc. In addition, there is a feature that the operation timing of the fire extinguisher is not shifted depending on the arrangement position of the sensor, and when a battery abnormality occurs and gas is discharged from the safety valve of the battery, this can be reliably detected. Moreover, since a fire extinguisher or an inert fluid is injected from the fire extinguisher into an exhaust chamber having a sealed structure, the fire extinguisher or the inert fluid can be effectively operated to effectively extinguish the fire.

さらに、本発明の請求項７の電源装置は、電池異常を極めて正確に、しかも速やかに検出して消火器を動作でき、消火器からケース内に効果的に消火剤を噴射できる特長がある。それは、この電源装置が、電池に安全弁の開弁を検出する開弁センサーを設けて、開弁センサーで消火器を制御するからである。この電源装置は、電池が異常な状態になって安全弁が開弁されると、開弁センサーが安全弁の開弁を検出して、消火器が消火剤を噴射する。この電源装置は、電池の安全弁の開弁を開弁センサーで検出して消火器を動作させるので、従来の温度センサーや煙センサー、ガスセンサー、炎センサー等のセンサーで電池の異常を検出する装置のように、消火器の動作タイミングがずれることがなく、電池異常が発生して安全弁が開弁すると、極めて正確なタイミングで消火剤を噴射できる。また、消火器からは密閉構造の排気室内に消火剤または不活性流体を噴射するので、消火剤や不活性流体を有効に作用させて、効果的に消火できる特徴も実現する。   Furthermore, the power supply device according to claim 7 of the present invention has a feature that the fire extinguisher can be operated by detecting a battery abnormality extremely accurately and promptly, and the fire extinguisher can be effectively injected into the case from the fire extinguisher. This is because the power supply device is provided with a valve opening sensor for detecting the opening of the safety valve in the battery, and the fire extinguisher is controlled by the valve opening sensor. In this power supply device, when the battery becomes abnormal and the safety valve is opened, the valve opening sensor detects the opening of the safety valve, and the fire extinguisher injects a fire extinguishing agent. This power supply device detects the opening of the safety valve of the battery with the valve opening sensor and operates the fire extinguisher, so it detects the abnormality of the battery with the conventional temperature sensor, smoke sensor, gas sensor, flame sensor, etc. In this way, the operation timing of the fire extinguisher is not shifted, and when a battery abnormality occurs and the safety valve opens, the fire extinguisher can be injected with extremely accurate timing. Moreover, since a fire extinguisher or an inert fluid is injected from the fire extinguisher into an exhaust chamber having a sealed structure, the fire extinguisher or the inert fluid can be effectively operated to effectively extinguish the fire.

However, the embodiments described below exemplify a power supply device for embodying the technical idea of the present invention, and the present invention does not specify the power supply device as follows.

図１ないし図６に示す電源装置は、安全弁１０を備える複数の電池１をケース２に収納している。これらの電源装置は、ケース２内を区画壁３でもって、複数の電池１を収納している電池室４と、この電池室４に収納される電池１の安全弁１０から排出されるガスを排気する排気室５とに区画している。   The power supply device shown in FIGS. 1 to 6 stores a plurality of batteries 1 including a safety valve 10 in a case 2. These power supply devices exhaust a gas discharged from a battery chamber 4 containing a plurality of batteries 1 and a safety valve 10 of the battery 1 housed in the battery chamber 4 with a partition wall 3 inside the case 2. The exhaust chamber 5 is partitioned.

電池１は、内圧が上昇するときに開弁する安全弁１０を備える。安全弁１０は、電池１の内圧が設定圧力よりも高くなると開弁する。安全弁１０が開弁されると、開口部１１からガスや電解液が排出されて、内圧上昇が阻止される。この電池１は、安全弁１０を開弁して外装缶１２の破裂を防止する。電池１はリチウムイオン二次電池である。ただ、本発明の電源装置は、電池をリチウムイオン二次電池には特定しない。電池には、ニッケル水素電池やニッケルカドミウム電池等の充電できる全ての電池を使用できる。   The battery 1 includes a safety valve 10 that opens when the internal pressure increases. The safety valve 10 opens when the internal pressure of the battery 1 becomes higher than the set pressure. When the safety valve 10 is opened, gas and electrolyte are discharged from the opening 11 to prevent an increase in internal pressure. The battery 1 opens the safety valve 10 to prevent the outer can 12 from bursting. The battery 1 is a lithium ion secondary battery. However, the power supply device of the present invention does not specify a battery as a lithium ion secondary battery. As the battery, any rechargeable battery such as a nickel metal hydride battery or a nickel cadmium battery can be used.

複数の電池１は、軸方向に平行に並べて電池室４に収納している。電池室４に配設される複数の電池１は、安全弁１０の開口部１１を排気室５に連通するように配設している。電池１の安全弁１０が開弁されて、安全弁１０から排出されるガスを、電池室４に流入させることなく排気室５に流入させるためである。図の電源装置は、安全弁１０を有する側の電池端部を区画壁３に密着させると共に、区画壁３に設けた貫通部６を介して安全弁１０の開口部１１を排気室５に連通させている。   The plurality of batteries 1 are accommodated in the battery chamber 4 in parallel in the axial direction. The plurality of batteries 1 disposed in the battery chamber 4 are disposed so that the opening 11 of the safety valve 10 communicates with the exhaust chamber 5. This is because the safety valve 10 of the battery 1 is opened, and the gas discharged from the safety valve 10 flows into the exhaust chamber 5 without flowing into the battery chamber 4. The power supply device shown in the figure has the battery end portion on the side having the safety valve 10 in close contact with the partition wall 3, and the opening portion 11 of the safety valve 10 communicates with the exhaust chamber 5 through the through portion 6 provided in the partition wall 3. Yes.

区画壁３は、非通気性の隔壁で、ケース２の内部を電池室４と排気室５とに区画している。さらに、区画壁３は、電池室４に配設される複数の電池１の電池端部に対向する位置に、安全弁１０から排出されるガスを排気室５に流入させる貫通部６を開口している。区画壁３は、この貫通部６の周囲に電池端部を気密に連結して、安全弁１０の開口部１１から排出されるガスを、電池室４に流入させることなく排気室５に流入させるようにしている。   The partition wall 3 is a non-breathable partition wall and partitions the inside of the case 2 into a battery chamber 4 and an exhaust chamber 5. Furthermore, the partition wall 3 has a through-hole 6 that allows the gas discharged from the safety valve 10 to flow into the exhaust chamber 5 at a position facing the battery ends of the plurality of batteries 1 disposed in the battery chamber 4. Yes. The partition wall 3 is airtightly connected to the periphery of the through-hole 6 so that the gas discharged from the opening 11 of the safety valve 10 flows into the exhaust chamber 5 without flowing into the battery chamber 4. I have to.

図１ないし図４の電源装置は、ケース２内の上側に電池室４を設けて、下側に排気室５を設けている。これらの電源装置は、複数の電池１を、区画壁３の上に載せて電池室４に並べて収納している。これらの図に示す電池１は、電池１の下側の端部に安全弁１０を設けている。図の電池１は、外装缶１２の底に安全弁１０を設けている。この安全弁１０は、電池１の内圧が設定圧力よりも高くなると破壊して開弁するもので、たとえば、図の一部拡大断面図に示すように、外装缶１２の金属板を部分的に薄くして、設定圧力で破壊されるようにしている。ただ、本発明は安全弁をこの構造には特定しない。安全弁には、内圧が設定圧力よりも高くなると開弁する全ての構造とすることができる。   1 to 4 includes a battery chamber 4 on the upper side in the case 2 and an exhaust chamber 5 on the lower side. In these power supply devices, a plurality of batteries 1 are placed on a partition wall 3 and stored side by side in a battery chamber 4. The battery 1 shown in these drawings is provided with a safety valve 10 at the lower end of the battery 1. In the illustrated battery 1, a safety valve 10 is provided at the bottom of the outer can 12. The safety valve 10 is broken and opened when the internal pressure of the battery 1 becomes higher than a set pressure. For example, as shown in a partially enlarged sectional view of the figure, the metal plate of the outer can 12 is partially thinned. Then, it is destroyed at the set pressure. However, the present invention does not specify a safety valve for this structure. The safety valve can have any structure that opens when the internal pressure becomes higher than the set pressure.

図１ないし図４に示す区画壁３の貫通部６は排気孔６Ａで、この排気孔６Ａを電池１の安全弁１０の開口部１１に対向して開口している。図に示す装置は、安全弁１０の開口部１１の周囲を区画壁３の排気孔６Ａの周囲に気密に固定して、電池端部を区画壁３に密着状態で固定している。電池端部は、区画壁３との間にシリコン等のシール剤や接着剤を塗布して、気密に連結している。この連結構造は、安全弁１０の開口部１１から排出されるガス等の流体を、電池室４内に流入させることなく排気孔６Ａから排気室５に流入できる。   The through portion 6 of the partition wall 3 shown in FIGS. 1 to 4 is an exhaust hole 6 </ b> A, and the exhaust hole 6 </ b> A is opposed to the opening 11 of the safety valve 10 of the battery 1. In the apparatus shown in the figure, the periphery of the opening 11 of the safety valve 10 is fixed in an airtight manner around the exhaust hole 6 </ b> A of the partition wall 3, and the battery end is fixed in close contact with the partition wall 3. The battery end portion is airtightly connected to the partition wall 3 by applying a sealing agent such as silicon or an adhesive. In this connection structure, fluid such as gas discharged from the opening 11 of the safety valve 10 can flow into the exhaust chamber 5 from the exhaust hole 6 </ b> A without flowing into the battery chamber 4.

図１の装置は、外装缶１２の底面である電池端面を、区画壁３の上面であって、排気孔６Ａの周囲に接着して密着状態に固定している。図２と図３に示す装置は、区画壁３の上面に、電池端部を挿入する凹部７を設けている。これらの装置は、凹部７に電池端部を挿入すると共に、凹部７の内面に電池端部を接着して固定している。図２に示す区画壁３は、電池端部を挿入できる凹部７を有する凹凸形状に成形して、この凹部７の中心に排気孔６Ａを開口している。さらに、図３に示す区画壁３は、排気孔６Ａの周囲にリブ８を設けて、電池端部を挿入する凹部７を成形している。   In the apparatus of FIG. 1, the battery end surface, which is the bottom surface of the outer can 12, is adhered to the periphery of the exhaust hole 6 </ b> A on the upper surface of the partition wall 3 and fixed in a close contact state. The apparatus shown in FIGS. 2 and 3 is provided with a recess 7 for inserting a battery end on the upper surface of the partition wall 3. In these devices, the battery end is inserted into the recess 7 and the battery end is adhered and fixed to the inner surface of the recess 7. The partition wall 3 shown in FIG. 2 is formed into a concavo-convex shape having a concave portion 7 into which a battery end can be inserted, and an exhaust hole 6 </ b> A is opened at the center of the concave portion 7. Further, the partition wall 3 shown in FIG. 3 is provided with a rib 8 around the exhaust hole 6A to form a recess 7 into which a battery end is inserted.

さらに、図４に示す電池１は、安全弁１０を有する側の電池端部にキャップ９を連結しており、このキャップ９を区画壁３に気密に固定している。キャップ９は、プラスチックまたはゴム等の絶縁材を成形して製作される。キャップ９は、電池端部を挿入できる周壁を備え、この周壁の内形を電池１の外形にほぼ等しくして、周壁と電池１の表面との隙間にシリコン等のシール剤や接着剤を塗布して、周壁を電池１の表面に気密に連結している。さらに、キャップ９は、端面に安全弁１０の開口部１１を外部に表出させる中心孔９Ａを開口している。キャップ９を連結している電池１は、キャップ９の端面を区画壁３に接着し、あるいは、キャップの端部を凹部に挿入して凹部とキャップの間にシリコン等のシール剤や接着剤を塗布して、区画壁３に気密に連結している。電池１の安全弁１０から排出されるガス等の流体は、キャップ９の中心孔９Ａと貫通部６である排気孔６Ａを通過して排気室５に流入される。このように、キャップを介して電池端部を区画壁３の貫通部６に気密に連結する構造は、安全弁１０から排出されるガス等が電池室４に流入するのを有効に防止できる。   Further, in the battery 1 shown in FIG. 4, a cap 9 is connected to the battery end portion on the side having the safety valve 10, and the cap 9 is fixed to the partition wall 3 in an airtight manner. The cap 9 is manufactured by molding an insulating material such as plastic or rubber. The cap 9 has a peripheral wall into which the end of the battery can be inserted. The inner shape of the peripheral wall is substantially equal to the outer shape of the battery 1, and a sealant or adhesive such as silicon is applied to the gap between the peripheral wall and the surface of the battery 1. The peripheral wall is airtightly connected to the surface of the battery 1. Further, the cap 9 has a central hole 9A at the end face for exposing the opening 11 of the safety valve 10 to the outside. The battery 1 connected to the cap 9 has the end face of the cap 9 adhered to the partition wall 3, or the end of the cap is inserted into the recess and a sealant or adhesive such as silicon is inserted between the recess and the cap. It is applied and connected to the partition wall 3 in an airtight manner. A fluid such as a gas discharged from the safety valve 10 of the battery 1 passes through the central hole 9 </ b> A of the cap 9 and the exhaust hole 6 </ b> A that is the through portion 6 and flows into the exhaust chamber 5. As described above, the structure in which the battery end is hermetically connected to the penetrating portion 6 of the partition wall 3 through the cap can effectively prevent the gas discharged from the safety valve 10 from flowing into the battery chamber 4.

図５と図６の電源装置は、ケース２内の上側に排気室５を設けて、下側に電池室４を設けている。この電源装置は、複数の電池１を、電池室５の底面の上に載せて電池室４に並べて収納している。これらの図に示す電池１は、電池１の上側の端部に安全弁１０を設けている。図の電池１は、外装缶１２の開口部を閉塞する封口板１３に安全弁１０を設けている。この安全弁１０は、図の一部拡大断面図に示すように、弾性体１４で弁体１５を弁座１６に押圧しており、電池１の内圧が設定圧力よりも高くなると、弁体１５が弁座１６から離れて開弁される。封口板１３は、凸部電極１７の両側に開口部１１を開口しており、安全弁１０が開弁すると、開口部１１からガスや電解液を排出する。   5 and 6 has an exhaust chamber 5 on the upper side in the case 2 and a battery chamber 4 on the lower side. In this power supply device, a plurality of batteries 1 are placed on the bottom surface of the battery chamber 5 and stored side by side in the battery chamber 4. The battery 1 shown in these drawings is provided with a safety valve 10 at the upper end of the battery 1. In the illustrated battery 1, a safety valve 10 is provided on a sealing plate 13 that closes an opening of an outer can 12. As shown in the partially enlarged cross-sectional view of the safety valve 10, the elastic body 14 presses the valve body 15 against the valve seat 16, and when the internal pressure of the battery 1 becomes higher than the set pressure, the valve body 15 The valve is opened away from the valve seat 16. The sealing plate 13 has openings 11 on both sides of the convex electrode 17, and discharges gas and electrolyte from the opening 11 when the safety valve 10 is opened.

図５に示す区画壁３の貫通部６は排気孔６Ａで、この排気孔６Ａを電池１の安全弁１０の開口部１１に対向して開口している。図に示す装置は、安全弁１０の開口部１１の周囲を区画壁３の排気孔６Ａの周囲に気密に固定して、電池端部を区画壁３に密着状態で固定している。図の電池１は、凸部電極側の端部にキャップ９を装着しており、このキャップ９の周壁と電池１の表面との隙間にシリコン等のシール剤や接着剤を塗布して気密に連結すると共に、キャップ９の端面と区画壁３との間にシリコン等のシール剤や接着剤を塗布して区画壁３に気密に連結している。このキャップ９には前述のキャップと同じものが使用できる。   The through-hole 6 of the partition wall 3 shown in FIG. 5 is an exhaust hole 6 </ b> A, and the exhaust hole 6 </ b> A is opposed to the opening 11 of the safety valve 10 of the battery 1. In the apparatus shown in the figure, the periphery of the opening 11 of the safety valve 10 is fixed in an airtight manner around the exhaust hole 6 </ b> A of the partition wall 3, and the battery end is fixed in close contact with the partition wall 3. The battery 1 shown in the figure has a cap 9 attached to the end on the convex electrode side, and a sealant such as silicon or an adhesive is applied to the gap between the peripheral wall of the cap 9 and the surface of the battery 1 to make it airtight. In addition to being connected, a sealing agent such as silicon or an adhesive is applied between the end face of the cap 9 and the partition wall 3 so as to be airtightly connected to the partition wall 3. This cap 9 can be the same as the cap described above.

図６に示す区画壁３の貫通部６は挿通孔６Ｂで、この挿通孔６Ｂに安全弁１０を備える電池端部を貫通して挿入し、安全弁１０の開口部１１を排気室５内に連通している。図に示す装置は、電池１の凸部電極側の端部にキャップ９を装着しており、このキャップ９の外周面を挿通孔６Ｂの内面に気密に固定して、電池端部を区画壁３に密着状態で固定している。挿通孔６Ｂの内形は、キャップ６の外形にほぼ等しくしており、キャップ９の周壁と区画壁３の挿通孔６Ｂの内面との隙間にシリコン等のシール剤や接着剤を塗布して気密に連結している。このキャップ９には前述のキャップと同じものが使用できる。図示しないが、キャップは、外周面に沿って凸条を設けて、この凸条を挿通孔の周縁部に密着させてより気密に固定することもできる。   The through-hole 6 of the partition wall 3 shown in FIG. 6 is an insertion hole 6B, and the battery end provided with the safety valve 10 is inserted through the insertion hole 6B, and the opening 11 of the safety valve 10 is communicated with the exhaust chamber 5. ing. In the apparatus shown in the figure, a cap 9 is attached to the end of the battery 1 on the convex electrode side, the outer peripheral surface of the cap 9 is airtightly fixed to the inner surface of the insertion hole 6B, and the end of the battery is partitioned. 3 is fixed in close contact. The inner shape of the insertion hole 6B is substantially equal to the outer shape of the cap 6, and a sealing agent such as silicon or an adhesive is applied to the gap between the peripheral wall of the cap 9 and the inner surface of the insertion hole 6B of the partition wall 3 to form an airtight. It is linked to. This cap 9 can be the same as the cap described above. Although not shown, the cap may be provided with a ridge along the outer peripheral surface, and the ridge may be brought into close contact with the peripheral edge of the insertion hole to be more airtightly fixed.

以上の構造で、電池１の安全弁１０の開口部１１を排気室５に連通させて配設する電源装置は、電池１が異常な温度となって安全弁１０が開弁されると、排出されるガス等の流体が排気室５に流入される。安全弁１０から排出されるガスは、電池室４に流入されることなく排気室５に流入されて、排気室５からケース２外に排出される。   With the above structure, the power supply device in which the opening 11 of the safety valve 10 of the battery 1 is arranged to communicate with the exhaust chamber 5 is discharged when the safety valve 10 is opened due to an abnormal temperature of the battery 1. A fluid such as a gas flows into the exhaust chamber 5. The gas discharged from the safety valve 10 flows into the exhaust chamber 5 without flowing into the battery chamber 4 and is discharged out of the case 2 from the exhaust chamber 5.

図に示す排気室５は、密閉構造としている。密閉構造の排気室５は、ここに連通されて表出する電池端部を、ゴミや水分、さらに塩分から保護できる。このため、電池端部にゴミが付着し、さらにこのゴミが結露して湿潤な状態となり、あるいは塩分を含む状態で湿潤となって、金属部分を腐食させるのを確実に防止できる。したがって、電池を高湿度な環境で使用し、あるいは塩分の多い環境で使用しながら、寿命を長くできる特徴がある。ただ、排気室は、密閉構造とすることなく開口部を設けて、外部に開放することもできる。この排気室は、電池から排出されるガスを、開口部からケース外に排出する。   The exhaust chamber 5 shown in the figure has a sealed structure. The exhaust chamber 5 having a sealed structure can protect the end portion of the battery communicated and exposed from dust, moisture, and salt. For this reason, it is possible to reliably prevent the dust from adhering to the end of the battery, and the dust from condensing into a wet state, or wet in a state containing salt, and corroding the metal part. Therefore, there is a feature that the life can be extended while the battery is used in a high humidity environment or in a salty environment. However, the exhaust chamber can be opened to the outside by providing an opening without having a sealed structure. The exhaust chamber discharges the gas discharged from the battery from the opening to the outside of the case.

密閉構造の排気室５は、排出口１８を設けており、電池１の安全弁１０から排出されて排気室５に流入されるガスを、排出口１８からケース２の外部に排出する。排出口１８は排出弁１９を有する。排出弁１９は正常時には閉弁されて、排気室５を密閉状態に保持する。排出弁１９は、排気室５の内圧が設定圧力になるときに開弁されて、排気室５内のガスを外部に排出する。この排出弁１９は、排気室５内の圧力が設定圧力よりも高くなると破壊されて開弁される破壊弁とすることができる。ただ、排出弁は、安全弁が開弁されたことを検出して動作するアクチュエータで開弁させる開閉弁とすることもできる。   The exhaust chamber 5 having a sealed structure is provided with a discharge port 18, and the gas discharged from the safety valve 10 of the battery 1 and flowing into the exhaust chamber 5 is discharged from the discharge port 18 to the outside of the case 2. The discharge port 18 has a discharge valve 19. The discharge valve 19 is closed during normal operation, and the exhaust chamber 5 is kept in a sealed state. The exhaust valve 19 is opened when the internal pressure of the exhaust chamber 5 reaches the set pressure, and exhausts the gas in the exhaust chamber 5 to the outside. The discharge valve 19 can be a break valve that is broken and opened when the pressure in the exhaust chamber 5 becomes higher than a set pressure. However, the discharge valve may be an on-off valve that is opened by an actuator that operates by detecting that the safety valve has been opened.

図７と図８は、排出弁１９の具体例を示す。図７の排出弁１９は、ケース２の外壁の一部を薄くしたものである。この排出弁１９は、排気室５内の内圧が設定圧力よりも高くなると、排気室５の薄い部分が破壊されて、排出弁１９を開弁状態とする。この排出弁１９は、構造を簡単にできる。図８の排出弁１９は、ケース２の外壁の一部に貫通孔２９を設けて、この貫通孔２９を弁膜３０で閉塞する。弁膜３０は、溶接または接着等の方法でケース２の外壁に連結されて、貫通孔２９を気密に閉塞する。この排出弁１９は、排気室５内の内圧が設定圧力よりも高くなると弁膜３０が外れ、あるいは破壊されて開弁する。   7 and 8 show specific examples of the discharge valve 19. The discharge valve 19 in FIG. 7 is obtained by thinning a part of the outer wall of the case 2. When the internal pressure in the exhaust chamber 5 becomes higher than the set pressure, the thin portion of the exhaust chamber 5 is destroyed, and the exhaust valve 19 opens the exhaust valve 19. The discharge valve 19 can be simplified in structure. In the discharge valve 19 of FIG. 8, a through hole 29 is provided in a part of the outer wall of the case 2, and the through hole 29 is closed with a valve membrane 30. The valve membrane 30 is connected to the outer wall of the case 2 by a method such as welding or adhesion, and closes the through hole 29 in an airtight manner. When the internal pressure in the exhaust chamber 5 becomes higher than the set pressure, the discharge valve 19 opens when the valve membrane 30 is removed or destroyed.

さらに、図３ないし図５に示す電源装置は、電池１が異常な状態となって安全弁１０からガス等の流体が排出されるとき、密閉構造の排気室５内に消火剤または不活性流体を噴射する消火器２０を備えている。図の排気室５は、消火器２０を連結するための連結口２１を有し、この連結口２１には、消火剤や不活性流体の導入弁２２を設けている。導入弁２２は、正常時には閉弁されて、排気室５を密閉状態に保持している。消火器２０は、消火剤または不活性流体を噴射する噴射口２３を連結口２１に連結している。消火器２０から消火剤や不活性流体が噴射されるとき、導入弁２２が開弁されて、消火器２０から噴射される消火剤や不活性流体をケース２内に供給する。図の導入弁２２は、たとえば消火器２０から噴射される消火剤や不活性流体で破壊される破壊弁である。ただし、導入弁は、消火器を動作状態とするアクチュエータで開弁される開閉弁とすることもできる。   3 to 5, when the battery 1 becomes abnormal and fluid such as gas is discharged from the safety valve 10, a fire extinguisher or an inert fluid is put into the exhaust chamber 5 having a sealed structure. A fire extinguisher 20 is provided. The illustrated exhaust chamber 5 has a connection port 21 for connecting the fire extinguisher 20, and the connection port 21 is provided with an introduction valve 22 for a fire extinguishing agent and an inert fluid. The introduction valve 22 is closed during normal operation to keep the exhaust chamber 5 in a sealed state. The fire extinguisher 20 connects an injection port 23 for injecting a fire extinguisher or an inert fluid to a connection port 21. When the fire extinguisher and the inert fluid are injected from the fire extinguisher 20, the introduction valve 22 is opened, and the fire extinguisher and the inert fluid injected from the fire extinguisher 20 are supplied into the case 2. The introduction valve 22 in the figure is a destruction valve that is destroyed by a fire extinguisher or an inert fluid injected from the fire extinguisher 20, for example. However, the introduction valve may be an on-off valve that is opened by an actuator that operates the fire extinguisher.

図３ないし図５の電源装置は、排気室５の排出口１８と連結口２１とを対向位置に配置している。この電源装置は、連結口２１から供給される消火剤や不活性流体を排気室５全体に通過させて、排出口１８から排出できる。この構造は、消火器２０から噴射される消火剤や不活性流体によって、電池１から供給されるガス等の流体による火災を速やかに消火し、あるいは、電池１から供給されるガス等の流体が発火するのを有効に防止する。さらに、この状態で、排出口１８の排出弁１９が開弁されて、排気室５からガス等の流体が速やかにケース２外に排出される。   In the power supply apparatus shown in FIGS. 3 to 5, the discharge port 18 and the connection port 21 of the exhaust chamber 5 are arranged at opposing positions. This power supply device can discharge the fire extinguishing agent and the inert fluid supplied from the connection port 21 through the exhaust port 5 through the exhaust port 5. This structure quickly extinguishes a fire caused by a fluid such as a gas supplied from the battery 1 by a fire extinguisher or an inert fluid ejected from the fire extinguisher 20, or a fluid such as a gas supplied from the battery 1 Effectively prevent ignition. Furthermore, in this state, the discharge valve 19 of the discharge port 18 is opened, and a fluid such as gas is quickly discharged from the case 2 from the exhaust chamber 5.

図３と図５の消火器２０は、密閉された排気室５の内圧を検出する圧力センサー２４に制御されて、排気室５の内圧が設定圧力よりも高くなると、排気室５内に消火剤または不活性流体を噴射する。図の電源装置は、圧力センサー２４で排気室５の圧力を検出する。圧力センサー２４は、消火器２０を動作させるアクチュエータ２５に連結している。   The fire extinguisher 20 in FIGS. 3 and 5 is controlled by a pressure sensor 24 that detects the internal pressure of the sealed exhaust chamber 5, and when the internal pressure of the exhaust chamber 5 becomes higher than the set pressure, the fire extinguisher is placed in the exhaust chamber 5. Alternatively, an inert fluid is sprayed. In the illustrated power supply apparatus, the pressure sensor 24 detects the pressure in the exhaust chamber 5. The pressure sensor 24 is connected to an actuator 25 that operates the fire extinguisher 20.

図４の消火器２０は、安全弁１０の開弁を検出する開弁センサー２６に制御されて、電池１の安全弁１０が開弁すると、排気室５内に消火剤または不活性流体を噴射する。図に示す電池１は、安全弁１０の開弁を検出する開弁センサー２６を備えている。この開弁センサーとして、たとえば、図示しないが、安全弁の弁部に配線を施し、弁作動によって配線が断線することで開弁を検知するセンサー等が使用できる。ただ、開弁センサーは、安全弁が開弁したことを検出できる他の全てのセンサーが使用できる。   The fire extinguisher 20 of FIG. 4 is controlled by a valve opening sensor 26 that detects the opening of the safety valve 10, and when the safety valve 10 of the battery 1 is opened, a fire extinguisher or an inert fluid is injected into the exhaust chamber 5. The battery 1 shown in the figure includes a valve opening sensor 26 that detects the opening of the safety valve 10. As this valve opening sensor, for example, although not shown, a sensor that detects the valve opening by wiring the valve portion of the safety valve and disconnecting the wiring by operating the valve can be used. However, any other sensor that can detect that the safety valve has opened can be used as the valve opening sensor.

さらに、本発明の電源装置は、消火器の動作を制御するセンサーとして、圧力センサーや開弁センサー以外のセンサーを使用することもできる。たとえば、電源装置は、温度センサー、煙センサー、ガスセンサー、炎センサー等のセンサーで電池室に収納された電池の異常や排気室の異常を検出して消火器を作動させることもできる。   Furthermore, the power supply device of the present invention can use a sensor other than the pressure sensor and the valve opening sensor as a sensor for controlling the operation of the fire extinguisher. For example, the power supply device can also operate the fire extinguisher by detecting an abnormality in the battery housed in the battery chamber or an abnormality in the exhaust chamber by a sensor such as a temperature sensor, a smoke sensor, a gas sensor, or a flame sensor.

アクチュエータ２５は、圧力センサー２４または開弁センサー２６からの信号で、排気室５内の圧力が設定圧力以上に上昇すると、消火器２０を操作して、消火剤または不活性流体を排気室５内に噴射させる。不活性流体は、窒素ガスや炭酸ガス等の不活性ガス、あるいは、絶縁オイル等の不活性液体である。消火器２０は、たとえば、圧縮ボンベに、炭酸ガス等の不活性ガスを充填している。この消火器２０は、充填している炭酸ガス等の不活性なガス圧で、炭酸水素ナトリウムを主成分とする粉末等の消火剤を排気室５内に噴射する。ただ、本発明は、消火器が噴射する消火剤を、炭酸水素ナトリウムを主成分とする粉末には特定しない。消火剤には、排気室内に噴射して、電池から排出されるガス等の流体を消火し、あるいは電池から排出されるガス等の流体の発火を防止し、あるいはまた、電池から排出されるガス等の流体を安全に外部に排出できる他の全てのものを使用できるからである。   The actuator 25 operates the fire extinguisher 20 when the pressure in the exhaust chamber 5 rises to a set pressure or more in response to a signal from the pressure sensor 24 or the valve opening sensor 26, and extinguishes or inert fluid in the exhaust chamber 5. To spray. The inert fluid is an inert gas such as nitrogen gas or carbon dioxide gas, or an inert liquid such as insulating oil. The fire extinguisher 20 is filled with an inert gas such as carbon dioxide in a compression cylinder, for example. The fire extinguisher 20 injects a fire extinguisher such as powder containing sodium hydrogen carbonate as a main component into the exhaust chamber 5 with an inert gas pressure such as a filled carbon dioxide gas. However, this invention does not specify the extinguishing agent which a fire extinguisher injects to the powder which has sodium hydrogen carbonate as a main component. A fire extinguishing agent is a gas that is injected into the exhaust chamber to extinguish a fluid such as a gas discharged from a battery, to prevent ignition of a fluid such as a gas discharged from a battery, or to be discharged from a battery. This is because all other fluids that can safely discharge fluid such as the like can be used.

さらに、密閉構造の排気室５は、その内部に、不活性流体を充填することができる。不活性流体は、窒素ガスや炭酸ガス等の不活性ガス、あるいは、絶縁オイル等の不活性液体である。このように排気室５に不活性流体を充填する電源装置は、排気室５内に充填される不活性流体でもって安全性をより高くできる特長がある。とくに、排気室５内に付活性ガスを充填して、電池１から可燃性ガスが排出されるときに、消火器２０から消火剤や不活性流体を噴射して、可燃性ガスをケース２外に排出する電源装置は、極めて安全性を高くできる。   Furthermore, the exhaust chamber 5 having a sealed structure can be filled with an inert fluid. The inert fluid is an inert gas such as nitrogen gas or carbon dioxide gas, or an inert liquid such as insulating oil. As described above, the power supply device that fills the exhaust chamber 5 with the inert fluid has a feature that the safety can be further enhanced by the inert fluid filled in the exhaust chamber 5. In particular, when the flammable gas is discharged from the battery 1 by filling the exhaust chamber 5 with the activating gas, a fire extinguisher or an inert fluid is jetted from the fire extinguisher 20 so that the flammable gas is removed from the case 2 The power supply apparatus that discharges the battery can be extremely safe.

図１ないし図４、及び図６の電源装置は、電池１の端部をポッティングして樹脂２７に埋設している。ポッティング樹脂２７は、たとえばシリコン樹脂等の絶縁性のある樹脂である。端部をポッティング樹脂２７に埋設する電池１は、ポッティングされない位置に安全弁１０の開口部１１を設ける。図１ないし図４の電池１は、外装缶１２の底部に安全弁１０の開口部１１を設け、図６の電源装置は、封口板１３に安全弁１０の開口部１１を設けている。   1 to 4 and 6, the end portion of the battery 1 is potted and embedded in the resin 27. The potting resin 27 is an insulating resin such as silicon resin. In the battery 1 whose end is embedded in the potting resin 27, the opening 11 of the safety valve 10 is provided at a position where no potting is performed. The battery 1 of FIGS. 1 to 4 has an opening 11 of the safety valve 10 at the bottom of the outer can 12, and the power supply device of FIG. 6 has the opening 11 of the safety valve 10 on the sealing plate 13.

さらに、図の電源装置は、ケース２内に回路基板２８を収納している。図１ないし図４の電源装置は電池室４に、図５と図６の電源装置は排気室５に、それぞれ回路基板２８を収納している。回路基板２８は、各々の電池１の電圧や温度を検出して、電池１の充放電をコントロールする制御回路を実装している。回路基板２８は、電池１の上方に水平な姿勢で配置されて、ポッティング樹脂２７に埋設される。図１ないし図４の電源装置は、電池室４の上部にポッティング樹脂２７を充填して、回路基板２８をポッティング樹脂２７に埋設し、さらに電池１の上部もポッティング樹脂２７に埋設している。この電源装置は、回路基板２８と電池１の両方をポッティング樹脂２７で絶縁しながら定位置に保持できる。図５と図６の電源装置は、排気室の上部にポッティング樹脂２７を充填して、回路基板２８をポッティング樹脂２７に埋設している。この電源装置は、回路基板２８を、電池１から排出されるガス等の流体から保護できる。このため、電池１の安全弁１０が開弁する異常な状態においても、回路基板２８に実装している制御回路を正常に動作させて、安全性を向上できる。   Further, the power supply device shown in the figure houses a circuit board 28 in the case 2. The power supply device shown in FIGS. 1 to 4 stores the circuit board 28 in the battery chamber 4, and the power supply device shown in FIGS. 5 and 6 stores the circuit board 28 in the exhaust chamber 5. The circuit board 28 is mounted with a control circuit that detects the voltage and temperature of each battery 1 and controls charging / discharging of the battery 1. The circuit board 28 is arranged in a horizontal posture above the battery 1 and is embedded in the potting resin 27. 1 to FIG. 4, the potting resin 27 is filled in the upper part of the battery chamber 4, the circuit board 28 is embedded in the potting resin 27, and the upper part of the battery 1 is also embedded in the potting resin 27. This power supply device can hold both the circuit board 28 and the battery 1 in place while insulating them with the potting resin 27. 5 and 6, the potting resin 27 is filled in the upper part of the exhaust chamber, and the circuit board 28 is embedded in the potting resin 27. The power supply device can protect the circuit board 28 from a fluid such as a gas discharged from the battery 1. For this reason, even in an abnormal state in which the safety valve 10 of the battery 1 is opened, the control circuit mounted on the circuit board 28 can be operated normally to improve safety.

電池室は、密閉構造とすることができる。密閉構造の電池室は、回路基板や電池を外部から遮断できるので、電池室内に収納される回路基板や電池をゴミと水分と塩分から有効に保護できる。さらに、密閉構造の電池室は、不活性流体を充填することもできる。ただ、図示しないが、電池室は、冷却用のダクトを連結すると共に、このダクトを介して冷却媒体を循環させて電池を冷却することもできる。   The battery chamber can be a sealed structure. Since the battery chamber having the sealed structure can block the circuit board and the battery from the outside, the circuit board and the battery housed in the battery chamber can be effectively protected from dust, moisture and salt. Furthermore, the battery chamber having a sealed structure can be filled with an inert fluid. However, although not shown, the battery chamber can connect a cooling duct and cool the battery by circulating a cooling medium through the duct.
