Description

本発明は、蓄電池システム及びその冷却制御方法に関する。 The present invention relates to a storage battery system and a cooling control method thereof.

リチウムイオン電池を代表とする蓄電池は、小型携帯機器の動作電源としてだけでなく、自動車や鉄道などの移動体動力電源や、再生可能エネルギー発電設備に併設する系統安定化電源などの大型のシステムにも適用されるようになったため、大型化している。特に、高い入出力特性が求められるハイブリッド鉄道車両などの蓄電池においては、蓄電池の冷却による温度制御が重要となる。 Storage batteries, such as lithium-ion batteries, can be used not only as operating power sources for small portable devices, but also for large-scale systems such as mobile power sources for automobiles and railways, and system-stabilized power sources installed in renewable energy power generation facilities. Has also been applied, so it is becoming larger. In particular, in a storage battery such as a hybrid railroad vehicle that requires high input / output characteristics, temperature control by cooling the storage battery is important.

そこで、蓄電池を冷却するために送風装置を用いて外気を取り込み、蓄電池を冷却する対策が取られている。 Therefore, measures have been taken to cool the storage battery by taking in outside air using a blower to cool the storage battery.

例えば、特許文献１には、「複数の蓄電池を有する蓄電装置と、蓄電装置の筐体であって、鉄道車両の走行に伴う走行風を通過させる開口部を備える筐体と、開口部の開放度合いを調整する絞り部材とを備える蓄電システム」の技術が開示されている。 For example, Patent Document 1 states, "A power storage device having a plurality of storage batteries, a housing of the power storage device having an opening for passing a running wind accompanying the running of a railroad vehicle, and an opening of the opening. The technology of "a power storage system including a throttle member for adjusting the degree" is disclosed.

上述したハイブリッド鉄道車両では、外気取込時に塵埃を蓄電池の筐体内部に取り込まないように、外気取込の開口部に塵埃取込防止フィルタを取り付ける必要があるが、頻繁に塵埃取込防止フィルタ交換が必要になると保守性が悪くなる課題がある。一方、外気取込量を低減するために、送風装置の送風量を下げると、蓄電池の温度が上昇し、蓄電池の性能が低下することが危惧される。 In the hybrid railroad vehicle described above, it is necessary to attach a dust intake prevention filter to the opening of the outside air intake so that dust is not taken into the housing of the storage battery when the outside air is taken in, but the dust intake prevention filter is frequently used. There is a problem that maintainability deteriorates when replacement is required. On the other hand, if the amount of air blown by the blower is reduced in order to reduce the amount of outside air taken in, the temperature of the storage battery may rise and the performance of the storage battery may deteriorate.

そこで、本発明の目的は、蓄電池を収納する筐体への外気の導入と導入遮断を筐体内外の状況に応じて選択することにある。 Therefore, an object of the present invention is to select the introduction and introduction cutoff of outside air into the housing for accommodating the storage battery according to the situation inside and outside the housing.

The housing includes a plurality of openings connected to the outside of the housing and the inside of the housing, and a plurality of movable partitions for opening and closing each of the plurality of openings, and the inside of the housing is discharged from the blower. An annular circulation flow path for guiding the air to the storage battery is formed, and the storage battery and the blower are arranged in the middle of the circulation flow path.

本発明によれば、蓄電池を収納する筐体への外気の導入と導入遮断を筐体内外の状況に応じて選択することができる。 According to the present invention, it is possible to select the introduction of outside air into the housing for accommodating the storage battery and the interruption of introduction according to the situation inside and outside the housing.

Each storage battery 101 and a blower 102 are arranged inside the housing 103.

蓄電池１０１は、電力を蓄電する蓄電装置であって、リチウムイオン電池や、鉛蓄電池、ニッケル水素電池、ニッケルカドミウム電池などが挙げられるが、これらに限定されない。 The storage battery 101 is a power storage device for storing electric power, and examples thereof include, but are not limited to, a lithium ion battery, a lead storage battery, a nickel hydrogen battery, and a nickel cadmium battery.

The blower 102 can discharge air whose amount of blown air changes according to an increase or decrease in the rotation speed of a propeller fan or a sirocco fan that can rotate in the forward and reverse directions.

筐体１０３は、箱型形状に形成され、蓄電池１０１および送風装置１０２を空間的に囲って収納し、蓄電池１０１を保護する役割のものであり、材料としては、鉄やアルミなどの金属部材や、樹脂系化合物などが挙げられるが、これらに限定されない。 The housing 103 is formed in a box shape, spatially surrounds and stores the storage battery 101 and the blower 102, and has a role of protecting the storage battery 101. As a material, a metal member such as iron or aluminum can be used. , Resin-based compounds, etc., but are not limited thereto.

筐体１０３の上部には、複数の開口１１０、１１１が吸排気口として形成されている。筐体１０３の内部には、各蓄電池１０１と送風装置１０２が配置されていると共に、断面形状が略Ｌ字形の仕切板１１２が配置されている。この際、筐体１０３の内部には、仕切板１１２によって、環状の空間部が形成されており、この環状の空間部は、開口１１０、１１１に連なる流路（風路）であって、送風装置１０２からの空気（風）を循環させるための、環状の循環流路（内気循環風路）１１３として形成されている。即ち、各蓄電池１０１と送風装置１０２が循環流路１１３の途中に配置され、各蓄電池１０１が循環流路１１３に沿って、上流側から下流側に向かって配置され、送風装置１０２からの空気（風）が循環流路１１３を循環する過程で、各蓄電池１０１が空気によって冷却されるようになっている。 A plurality of openings 110 and 111 are formed as intake / exhaust ports on the upper portion of the housing 103. Inside the housing 103, each storage battery 101 and a blower 102 are arranged, and a partition plate 112 having a substantially L-shaped cross section is arranged. At this time, an annular space is formed inside the housing 103 by a partition plate 112, and the annular space is a flow path (air passage) connected to the openings 110 and 111 to blow air. It is formed as an annular circulation flow path (inside air circulation air passage) 113 for circulating air (wind) from the device 102. That is, each storage battery 101 and the blower 102 are arranged in the middle of the circulation flow path 113, and each storage battery 101 is arranged from the upstream side to the downstream side along the circulation flow path 113, and the air from the blower device 102 ( Each storage battery 101 is cooled by air in the process of circulating the wind) in the circulation flow path 113.

この際、仕切板１１２の一部は、各蓄電池１０１と送風装置１０２とを分離するための隔壁として構成されている。 At this time, a part of the partition plate 112 is configured as a partition wall for separating each storage battery 101 and the blower 102.

各蓄電池１０１のうち一方の蓄電池１０１の上部には、蓄電池１０１の温度や筐体１０３内の温度を検出する温度センサ１０７が、開口１１０に相対向して配置され、他方の蓄電池１０１の上部には、蓄電池１０１の温度や筐体１０３内の温度を検出する温度センサ１０８が配置されている。送風装置１０２は、開口１１１に相対向した位置に配置されている。 A temperature sensor 107 for detecting the temperature of the storage battery 101 and the temperature inside the housing 103 is arranged on the upper part of one of the storage batteries 101 so as to face the opening 110, and on the upper part of the other storage battery 101. Is arranged with a temperature sensor 108 that detects the temperature of the storage battery 101 and the temperature inside the housing 103. The blower 102 is arranged at a position facing the opening 111.

筐体１０３の外部と内部に連なる開口１１０には、開口１１０を開閉する可動仕切り１１４が配置されている。筐体１０３の外部と内部に連なる開口１１１には、開口１１１を開閉する可動仕切り１１５が配置されている。可動仕切り１１４は、可動仕切り１１４を開閉駆動する開閉機構１０５に接続される。開閉機構１０５は、開閉機構１０５に対して、制御信号によって開駆動又は閉駆動を指令する制御装置１０４に接続されている。可動仕切り１１５は、可動仕切り１１５を開閉駆動する開閉機構１０６に接続される。開閉機構１０６は、可動仕切り１１６に対して、制御信号によって開駆動又は閉駆動を指令する制御装置１０４に接続されている。 A movable partition 114 for opening and closing the opening 110 is arranged in the opening 110 connected to the outside and the inside of the housing 103. A movable partition 115 that opens and closes the opening 111 is arranged in the opening 111 that is connected to the outside and the inside of the housing 103. The movable partition 114 is connected to an opening / closing mechanism 105 that drives the opening / closing of the movable partition 114. The opening / closing mechanism 105 is connected to a control device 104 that commands an opening / closing drive or a closing drive to the opening / closing mechanism 105 by a control signal. The movable partition 115 is connected to an opening / closing mechanism 106 that drives the movable partition 115 to open / close. The opening / closing mechanism 106 is connected to a control device 104 that commands an open drive or a closed drive to the movable partition 116 by a control signal.

制御装置１０４は、例えば、ＣＰＵ（Central Processing Unit）、メモリ、入出力インタフェース等の情報処理資源を備えたコンピュータ装置で構成される。周囲温度（外気温）を検出する外気温センサ１０９からの検出信号、及び蓄電池１０１の温度を検出する温度センサ１０７、１０８からの検出信号を取り込み、蓄電池１０１の温度と周囲温度を基に送風装置１０２の回転数を制御するための制御信号及び開閉機構１０５、１０６を開閉駆動するための制御信号を生成し、生成した制御信号を送風装置１０２と開閉機構１０５、１０６に出力する。この際、制御装置１０４は、送風装置１０２の送風量と送風装置１０２の回転数とを関連づけて管理すると共に、送風装置１０２の騒音レベルと送風装置１０２の回転数とを関連づけて管理する。また、制御装置１０４は、各温度センサ１０７、１０８の検出温度を閾値に関連づけて管理する。 The control device 104 is composed of, for example, a computer device including information processing resources such as a CPU (Central Processing Unit), a memory, and an input / output interface. The detection signal from the outside temperature sensor 109 that detects the ambient temperature (outside temperature) and the detection signals from the temperature sensors 107 and 108 that detect the temperature of the storage battery 101 are taken in, and the blower device is based on the temperature of the storage battery 101 and the ambient temperature. A control signal for controlling the number of rotations of 102 and a control signal for driving the opening / closing mechanisms 105 and 106 are generated, and the generated control signal is output to the blower 102 and the opening / closing mechanisms 105 and 106. At this time, the control device 104 manages the blower amount of the blower 102 and the rotation speed of the blower 102 in association with each other, and manages the noise level of the blower 102 and the rotation speed of the blower 102 in association with each other. Further, the control device 104 manages the detected temperatures of the temperature sensors 107 and 108 in association with the threshold value.

例えば、制御装置１０４は、温度センサ１０７の検出温度が、第１の蓄電池温度閾値を超えるまでは、各開閉機構１０５、１０６に対して閉駆動を指令し、温度センサ１０７の検出温度が、第１の蓄電池温度閾値を超えたことを条件に、各開閉機構１０５、１０６に対して開駆動を指令する。すなわち、温度センサ１０７の検出温度が、第１の蓄電池温度閾値を超えるまでは、各開閉機構１０５、１０６の閉駆動により、開口１１０、１１０を可動仕切り１１４、１１５によって閉じ、筐体１０３内を密閉状態とする。その後、温度センサ１０７の検出温度が、第１の蓄電池温度閾値を超えたことを条件に、各開閉機構１０５、１０６の開駆動により、開口１１０、１１０を可動仕切り１１４、１１５によって開き、筐体１０３内に開口１１０から外気を導入し、筐体１０３内の空気を開口１１１から排出する。 For example, the control device 104 commands the opening / closing mechanisms 105 and 106 to close and drive until the detected temperature of the temperature sensor 107 exceeds the first storage battery temperature threshold, and the detected temperature of the temperature sensor 107 becomes the first. On condition that the temperature threshold of the storage battery of 1 is exceeded, the opening / closing mechanisms 105 and 106 are instructed to open drive. That is, until the detection temperature of the temperature sensor 107 exceeds the first storage battery temperature threshold value, the openings 110 and 110 are closed by the movable partitions 114 and 115 by the closing drive of the opening and closing mechanisms 105 and 106, and the inside of the housing 103 is closed. Keep it sealed. After that, on condition that the detected temperature of the temperature sensor 107 exceeds the first storage battery temperature threshold value, the openings 110 and 110 are opened by the movable partitions 114 and 115 by the opening drive of the opening / closing mechanisms 105 and 106, and the housing is opened. The outside air is introduced into the 103 through the opening 110, and the air in the housing 103 is discharged from the opening 111.

これにより、温度センサ１０７の検出温度が、第１の蓄電池温度閾値を超えるまでは、筐体１０３内を密閉状態に保った状態で各蓄電池１０１を送風装置１０２からの空気で冷却することができ、筐体１０３内に塵埃が入り込むのを防止することができると共に、送風装置１０２の運転に伴う騒音が筐体１０３外に漏れるのを防止することができる。また、温度センサ１０７の検出温度が、第１の蓄電池温度閾値を超えた場合には、筐体１０３内に開口１１０から外気を導入し、筐体１０３内の空気を開口１１１から排出することで、各蓄電池１０１の温度上昇を抑制することができる。 As a result, until the detection temperature of the temperature sensor 107 exceeds the first storage battery temperature threshold value, each storage battery 101 can be cooled by the air from the blower 102 while the inside of the housing 103 is kept in a sealed state. It is possible to prevent dust from entering the housing 103, and it is possible to prevent noise caused by the operation of the blower 102 from leaking to the outside of the housing 103. When the detected temperature of the temperature sensor 107 exceeds the first storage battery temperature threshold value, outside air is introduced into the housing 103 from the opening 110, and the air inside the housing 103 is discharged from the opening 111. , The temperature rise of each storage battery 101 can be suppressed.

また、制御装置１０４は、各開閉機構１０５、１０６に対して開駆動を指令した後、例えば、温度センサ１０７の検出温度が、第１の蓄電池温度閾値より低い第２の蓄電池温度閾値以下に低下するまでは、各開閉機構１０５、１０６に対する開駆動の指令を保持し、その後、温度センサ１０７の検出温度が、第２の蓄電池温度閾値よりも低下したことを条件に、各開閉機構１０５、１０６に対して閉駆動を指令する。この際、第１の蓄電池温度閾値と第２の蓄電池温度閾値との間の温度領域がバッファ温度領域となり、温度センサ１０７の検出温度の変化によって、可動仕切り１１４、１１５が頻繁に開閉されるのを抑制することができ、可動仕切り１１４、１１５と開閉機構１０５、１０６の信頼性の向上に寄与することができる。 Further, after the control device 104 commands the opening / closing mechanisms 105 and 106 to open drive, for example, the detection temperature of the temperature sensor 107 drops below the second storage battery temperature threshold, which is lower than the first storage battery temperature threshold. Until this is done, the open drive command for each of the opening / closing mechanisms 105 and 106 is held, and then, on the condition that the detected temperature of the temperature sensor 107 is lower than the second storage battery temperature threshold, the opening / closing mechanisms 105 and 106 are held. Is instructed to close drive. At this time, the temperature region between the first storage battery temperature threshold value and the second storage battery temperature threshold value becomes the buffer temperature region, and the movable partitions 114 and 115 are frequently opened and closed by the change in the detection temperature of the temperature sensor 107. Can contribute to improving the reliability of the movable partitions 114 and 115 and the opening and closing mechanisms 105 and 106.

さらに、制御装置１０４は、外気温センサ１０９の検出温度が、例えば、温度センサ１０７の検出温度よりも高くなったことを条件に、各開閉機構１０５、１０６に対して強制的に閉駆動を指令する。これにより、外気温が、筐体１０３内の温度よりも高くなった場合には、開口１１０、１１０を可動仕切り１１４、１１５によって閉じて外気導入を遮断し、筐体１０３内を密閉状態とすることで、外気によって筐体１０３内の温度が上昇するのを抑制することができる。この場合、送風装置１０２の運転による空気が循環流路１１３を流れることによって各蓄電池１０１が冷却される。 Further, the control device 104 forcibly commands the opening / closing mechanisms 105 and 106 to be closed, provided that the detection temperature of the outside air temperature sensor 109 is higher than the detection temperature of the temperature sensor 107, for example. To do. As a result, when the outside air temperature becomes higher than the temperature inside the housing 103, the openings 110 and 110 are closed by the movable partitions 114 and 115 to block the introduction of outside air, and the inside of the housing 103 is sealed. As a result, it is possible to prevent the temperature inside the housing 103 from rising due to the outside air. In this case, each storage battery 101 is cooled by the air generated by the operation of the blower 102 flowing through the circulation flow path 113.

また、制御装置１０４は、循環流路１１３の上流側に配置された蓄電池１０１の温度を検出する上流側温度センサ、例えば、温度センサ１０７の検出温度よりも、循環流路１１３の下流側に配置された蓄電池１０１の温度を検出する下流側温度センサ、例えば、温度センサ１０８の検出温度の方が高い場合、送風装置１０２に対して、送風装置１０２から排出される空気の流れる方向を逆方向とする運転を実行する。これにより、循環流路１１３には、逆方向の空気が流れるので、送風装置１０２からの空気は、温度センサ１０８が配置された蓄電池１０１を冷却した後、温度センサ１０７が配置された蓄電池１０１を冷却することになる。この結果、温度センサ１０８が配置された蓄電池１０１の温度上昇を抑制することができる。 Further, the control device 104 is arranged on the downstream side of the circulation flow path 113 with respect to the temperature detected by the upstream temperature sensor, for example, the temperature sensor 107, which detects the temperature of the storage battery 101 arranged on the upstream side of the circulation flow path 113. When the temperature detected by the downstream temperature sensor that detects the temperature of the storage battery 101, for example, the temperature sensor 108, is higher, the direction in which the air discharged from the blower 102 flows is opposite to that of the blower 102. Perform the operation to do. As a result, air flows in the circulation flow path 113 in the opposite direction. Therefore, the air from the blower 102 cools the storage battery 101 in which the temperature sensor 108 is arranged, and then drives the storage battery 101 in which the temperature sensor 107 is arranged. It will be cooled. As a result, it is possible to suppress the temperature rise of the storage battery 101 in which the temperature sensor 108 is arranged.

また、制御装置１０４は、蓄電池１０１が搭載された車両（ハイブリッド鉄道車両）が停車中であるか否かを検出し、この検出結果を制御装置１０４に出力する停車センサ１１６の出力を取り込み、停車センサ１１６が、車両が停車中であることを検出したことを条件に、各開閉機構１０５、１０６に対して強制的に閉駆動を指令する。これにより、開口１１０、１１０を可動仕切り１１４、１１５によって閉じて外気導入を遮断し、筐体１０３内を密閉状態とすることで、車両の停車中、送風装置１０２の運転に伴う騒音が筐体１０３外に漏れるのを防止することができる。 Further, the control device 104 detects whether or not the vehicle (hybrid railway vehicle) on which the storage battery 101 is mounted is stopped, captures the output of the stop sensor 116 that outputs the detection result to the control device 104, and stops the vehicle. On condition that the sensor 116 detects that the vehicle is stopped, the sensor 116 forcibly commands the opening / closing mechanisms 105 and 106 to close the drive. As a result, the openings 110 and 110 are closed by the movable partitions 114 and 115 to block the introduction of outside air, and the inside of the housing 103 is sealed, so that the noise caused by the operation of the blower 102 is generated by the housing while the vehicle is stopped. It is possible to prevent the 103 from leaking to the outside.

また、制御装置１０４は、蓄電池１０１が搭載された車両（ハイブリッド鉄道車両）が加速状態にあることを検出し、この検出結果を制御装置１０４に出力する加速センサ１１７の出力を取り込み、加速センサ１１７の検出結果から、車両の加速状態が塵埃レベル閾値に相当する加速状態閾値を超えたことを条件に、各開閉機構１０５、１０６に対して強制的に閉駆動を指令する。これにより、開口１１０、１１０を可動仕切り１１４、１１５によって閉じて外気導入を遮断し、筐体１０３内を密閉状態とすることで、車両が加速状態にある場合、車両の加速に伴う塵埃（エンジンの排ガス）が筐体１０３内に取り込まるのを防止することができる。なお、加速センサ１１７は、例えば、アクセルペダルの踏み込み量を検出するセンサで構成することができる。 Further, the control device 104 detects that the vehicle (hybrid railway vehicle) on which the storage battery 101 is mounted is in an accelerating state, captures the output of the acceleration sensor 117 that outputs the detection result to the control device 104, and takes in the output of the acceleration sensor 117. On the condition that the acceleration state of the vehicle exceeds the acceleration state threshold value corresponding to the dust level threshold value, the closing drive is forcibly ordered to the opening / closing mechanisms 105 and 106. As a result, the openings 110 and 110 are closed by the movable partitions 114 and 115 to block the introduction of outside air, and the inside of the housing 103 is sealed. Therefore, when the vehicle is in an accelerating state, dust (engine) accompanying the acceleration of the vehicle (Exhaust gas) can be prevented from being taken into the housing 103. The acceleration sensor 117 can be composed of, for example, a sensor that detects the amount of depression of the accelerator pedal.

図３は、本発明の実施例に係る蓄電池システムの動作を説明するための説明図であって、（ａ）は、可動仕切りが「開」の状態における空気の流れを説明するための説明図であり、（ｂ）は、可動仕切りが「閉」の状態における空気の流れを説明するための説明図である。 FIG. 3 is an explanatory diagram for explaining the operation of the storage battery system according to the embodiment of the present invention, and FIG. 3A is an explanatory diagram for explaining the air flow in the state where the movable partition is “open”. (B) is an explanatory diagram for explaining the air flow in the state where the movable partition is “closed”.

図３（ａ）に示すように、可動仕切り１１４、１１５がそれぞれ開閉機構１０５、１０６の駆動により「開」の状態になった場合、送風装置１０２の運転による空気（風）は、送風装置１０２から開口１１１を介して筐体１０３の外部に排出されると共に、筐体１０３の外部から、開口１１０を介して筐体１０３内に外気が導入される。筐体１０３内に導入された外気は、各蓄電池１０１を介して送風装置１０２に導入され、導入された外気は、送風装置１０２の運転に従って、開口１１１を介して筐体１０３の外部に排出される。これにより、各蓄電池１０１は、外気によって冷却される。なお、この場合、送風装置１０２で生み出される空気は、循環流路１１３を循環することなく、外気とともに、開口１１１を介して筐体１０３の外部に排出される。 As shown in FIG. 3A, when the movable partitions 114 and 115 are brought into the “open” state by driving the opening / closing mechanisms 105 and 106, respectively, the air (wind) generated by the operation of the blower 102 is the blower 102. Is discharged to the outside of the housing 103 through the opening 111, and outside air is introduced into the housing 103 from the outside of the housing 103 through the opening 110. The outside air introduced into the housing 103 is introduced into the blower 102 via each storage battery 101, and the introduced outside air is discharged to the outside of the housing 103 through the opening 111 according to the operation of the blower 102. To. As a result, each storage battery 101 is cooled by the outside air. In this case, the air produced by the blower 102 is discharged to the outside of the housing 103 through the opening 111 together with the outside air without circulating in the circulation flow path 113.

図３（ｂ）に示すように、可動仕切り１１４、１１５がそれぞれ開閉機構１０５、１０６の駆動により「閉」の状態になった場合、送風装置１０２の運転による空気（風）は、循環流路１１３を循環する。この場合、送風装置１０２で生み出される空気は、必ず循環流路１１３を循環することになる。これにより、各蓄電池１０１は、循環流路１１３を循環する空気によって冷却される。 As shown in FIG. 3B, when the movable partitions 114 and 115 are brought into the “closed” state by driving the opening / closing mechanisms 105 and 106, respectively, the air (wind) generated by the operation of the blower 102 is circulated through the circulation flow path. Circulate 113. In this case, the air produced by the blower 102 always circulates in the circulation flow path 113. As a result, each storage battery 101 is cooled by the air circulating in the circulation flow path 113.

図４は、本発明の実施例に係る蓄電池システムにおける送風装置の送風量と蓄電池の温度変化との関係を示す特性図である。 FIG. 4 is a characteristic diagram showing the relationship between the amount of air blown by the blower device and the temperature change of the storage battery in the storage battery system according to the embodiment of the present invention.

図４において、送風装置１０２を運転して各蓄電池１０１の温度を計測したところ、各蓄電池１０１の温度が、送風装置１０２の送風量Ｖ（Ｌ/ｍｉｎ）の増加に従って低下し、各蓄電池１０１の温度のばらつきを示す温度差ΔＴ（Ｋ）も、特性Ｘ１で示すように、送風装置１０２の送風量Ｖ（Ｌ/ｍｉｎ）の増加に従って低下する結果が得られた。また、各蓄電池１０１の中の最高温度と周囲温度との差を示す温度差ΔＴ（Ｋ）を計測したところ、特性Ｘ２で示すように、送風装置１０２の送風量Ｖ（Ｌ/ｍｉｎ）の増加に従って低下する結果が得られた。 In FIG. 4, when the temperature of each storage battery 101 was measured by operating the blower 102, the temperature of each storage battery 101 decreased as the amount of air blown V (L / min) of the blower 102 increased, and the temperature of each storage battery 101 decreased. As shown in the characteristic X1, the temperature difference ΔT (K), which indicates the temperature variation, also decreased as the air flow rate V (L / min) of the air blower 102 increased. Further, when the temperature difference ΔT (K) indicating the difference between the maximum temperature in each storage battery 101 and the ambient temperature was measured, as shown by the characteristic X2, the amount of air blown V (L / min) of the blower device 102 increased. The result was that it decreased as a result.

図５は、本発明の実施例に係る蓄電池システムにおける送風装置の送風量と騒音レベルとの関係を示す特性図である。 FIG. 5 is a characteristic diagram showing the relationship between the amount of air blown by the blower device and the noise level in the storage battery system according to the embodiment of the present invention.

図５において、送風装置１０２を運転して、送風装置１０２の回転数に関連する、送風装置１０２の送風量Ｖ（Ｌ/ｍｉｎ）と騒音レベルＮＬ（Ｄｂ）を計測したところ、可動仕切り１１４、１１５が「開」の場合、特性Ｙ１で示すように、送風装置１０２の送風量Ｖ（Ｌ/ｍｉｎ）の増加に従って騒音レベルＮＬ（Ｄｂ）が増加する結果が得られ、可動仕切り１１４、１１５が「閉」の場合、特性Ｙ２で示すように、送風装置１０２の送風量Ｖ（Ｌ/ｍｉｎ）の増加に従って騒音レベルＮＬ（Ｄｂ）が増加する結果が得られた。 In FIG. 5, when the blower 102 was operated and the blower amount V (L / min) and the noise level NL (Db) of the blower 102 related to the rotation speed of the blower 102 were measured, the movable partition 114, When 115 is “open”, as shown by the characteristic Y1, the result is that the noise level NL (Db) increases as the air flow amount V (L / min) of the blower device 102 increases, and the movable partitions 114 and 115 In the case of "closed", as shown by the characteristic Y2, the result was obtained that the noise level NL (Db) increased as the air flow amount V (L / min) of the blower device 102 increased.

上記結果から、可動仕切り１１４、１１５が「開」の場合も「閉」の場合も、送風装置１０２の送風量Ｖ（Ｌ/ｍｉｎ）の増加に従って騒音レベルＮＬ（Ｄｂ）が増加するが、可動仕切り１１４、１１５が「閉」の場合は、可動仕切り１１４、１１５が「開」の場合よりも、騒音レベルＮＬ（Ｄｂ）が低下することが分かる。 From the above results, when the movable partitions 114 and 115 are "open" and "closed", the noise level NL (Db) increases as the air flow amount V (L / min) of the blower device 102 increases, but it is movable. It can be seen that when the partitions 114 and 115 are “closed”, the noise level NL (Db) is lower than when the movable partitions 114 and 115 are “open”.

図６は、本発明の実施例に係る蓄電池システムにおける蓄電池温度と周囲温度に応じた可動仕切りの状態説明図である。 FIG. 6 is an explanatory diagram of a state of a movable partition according to a storage battery temperature and an ambient temperature in the storage battery system according to the embodiment of the present invention.

図６において、送風装置１０２を運転して蓄電池１０１の温度Ｔ１（℃）と周囲温度Ｔ２（℃）を計測したところ、可動仕切り１１４、１１５が「閉」の場合、周囲温度Ｔ２が、設定された周囲温度領域Ａ１内にあることを条件に、蓄電池１０１の温度Ｔ１を、第１の蓄電池温度閾値ｔｈ１以下に保持できる結果が得られた。一方、蓄電池１０１の温度Ｔ１が、第１の蓄電池温度閾値ｔｈ１を超えた場合には、可動仕切り１１４、１１５を「開」とすることで、筐体１０３内に外気が導入されるので、周囲温度Ｔ２を、設定された周囲温度領域Ａ２内に保持できる結果が得られた。 In FIG. 6, when the temperature T1 (° C.) and the ambient temperature T2 (° C.) of the storage battery 101 are measured by operating the blower 102, the ambient temperature T2 is set when the movable partitions 114 and 115 are “closed”. The result was obtained that the temperature T1 of the storage battery 101 could be kept below the first storage battery temperature threshold th1 on condition that the temperature T1 was within the ambient temperature region A1. On the other hand, when the temperature T1 of the storage battery 101 exceeds the first storage battery temperature threshold th1, the movable partitions 114 and 115 are set to "open" so that the outside air is introduced into the housing 103. The result was that the temperature T2 could be kept within the set ambient temperature range A2.

上記結果から、可動仕切り１１４、１１５を「閉」とする時間帯を長くすることで、筐体１０３内への外気取込量を低減し、外気と一緒に取込まれる塵埃の量も低減することが可能になる。 From the above results, by lengthening the time zone in which the movable partitions 114 and 115 are "closed", the amount of outside air taken into the housing 103 is reduced, and the amount of dust taken in together with the outside air is also reduced. Will be possible.

図７は、本発明の実施例に係る蓄電池システムにおける蓄電池温度と周囲温度に応じた可動仕切りの状態説明図である。 FIG. 7 is an explanatory diagram of the state of the movable partition according to the storage battery temperature and the ambient temperature in the storage battery system according to the embodiment of the present invention.

図７において、送風装置１０２を運転して蓄電池１０１の温度Ｔ１（℃）と周囲温度Ｔ２（℃）を計測したところ、可動仕切り１１４、１１５が「閉」の場合、蓄電池１０１の温度Ｔ１が、第１の蓄電池温度閾値ｔｈ１より低い第２の蓄電池温度閾値ｔｈ２であれば、周囲温度Ｔ２を、設定された周囲温度領域Ａ３内に保持できる結果が得られた。一方、蓄電池１０１の温度Ｔ１が、第１の蓄電池温度閾値ｔｈ１を超えた場合、可動仕切り１１４、１１５を「開」にすることで、筐体１０３内に外気が導入されるので、周囲温度Ｔ２を、設定された周囲温度領域Ａ５内に保持できる結果が得られた。また、蓄電池１０１の温度Ｔ１が、第２の蓄電池温度閾値ｔｈ２を超えても、第１の蓄電池温度閾値ｔｈ１以下であれば、可動仕切り１１４、１１５を「閉」とする状態を継続しても、周囲温度Ｔ２を、設定された周囲温度領域Ａ４（周囲温度領域Ａ３と周囲温度領域Ａ５との間の領域）内に保持できる結果が得られた。さらに、蓄電池１０１の温度Ｔ１が、第１の蓄電池温度閾値ｔｈ１よりも低下しても、第２の蓄電池温度閾値ｔｈ１になるまでは、可動仕切り１１４、１１５を「開」とする状態を継続しても、周囲温度Ｔ２を、設定された周囲温度領域Ａ４内に保持できる結果が得られた。 In FIG. 7, when the temperature T1 (° C.) and the ambient temperature T2 (° C.) of the storage battery 101 are measured by operating the blower 102, when the movable partitions 114 and 115 are "closed", the temperature T1 of the storage battery 101 is determined. If the second storage battery temperature threshold th2 is lower than the first storage battery temperature threshold th1, the result is obtained that the ambient temperature T2 can be kept within the set ambient temperature region A3. On the other hand, when the temperature T1 of the storage battery 101 exceeds the first storage battery temperature threshold th1, the outside air is introduced into the housing 103 by opening the movable partitions 114 and 115, so that the ambient temperature T2 Was obtained in the set ambient temperature range A5. Further, even if the temperature T1 of the storage battery 101 exceeds the second storage battery temperature threshold th2 and is equal to or less than the first storage battery temperature threshold th1, even if the movable partitions 114 and 115 are kept "closed". The result was obtained that the ambient temperature T2 could be maintained within the set ambient temperature region A4 (the region between the ambient temperature region A3 and the ambient temperature region A5). Further, even if the temperature T1 of the storage battery 101 falls below the first storage battery temperature threshold th1, the movable partitions 114 and 115 continue to be "open" until the second storage battery temperature threshold th1 is reached. However, the result was obtained that the ambient temperature T2 could be kept within the set ambient temperature region A4.

上記結果から、可動仕切り１１４、１１５の開閉状態を制御する場合、可動仕切り１１４、１１５が「閉」の状態で送風装置１０２を運転しても、蓄電池１０１の温度Ｔ１が、第１の蓄電池温度閾値ｔｈ１を超えるまでは、周囲温度Ｔ２を、設定された周囲温度領域Ａ３、Ａ４内に保持できる。また、可動仕切り１１４、１１５が「開」の状態で送風装置１０２を運転しても、蓄電池１０１の温度Ｔ１が、第２の蓄電池温度閾値ｔｈ２になるまでは、周囲温度Ｔ２を、設定された周囲温度領域Ａ４、Ａ５内に保持できる。すなわち、周囲温度領域Ａ４をバッファ領域として、可動仕切り１１４、１１５の開閉状態を制御することができ、結果として、可動仕切り１１４、１１５の開閉状態が、蓄電池１０１の温度変化に応じて短時間で切り替わるのを抑制することができ、可動仕切り１１４、１１５の長寿命化を図ることが可能になる。 From the above results, when controlling the open / closed state of the movable partitions 114 and 115, even if the blower 102 is operated with the movable partitions 114 and 115 "closed", the temperature T1 of the storage battery 101 is the temperature of the first storage battery. The ambient temperature T2 can be kept within the set ambient temperature regions A3 and A4 until the threshold th1 is exceeded. Further, even if the blower 102 is operated with the movable partitions 114 and 115 "open", the ambient temperature T2 is set until the temperature T1 of the storage battery 101 reaches the second storage battery temperature threshold value th2. It can be kept in the ambient temperature regions A4 and A5. That is, the open / closed state of the movable partitions 114 and 115 can be controlled by using the ambient temperature region A4 as the buffer area, and as a result, the open / closed state of the movable partitions 114 and 115 can be changed in a short time according to the temperature change of the storage battery 101. Switching can be suppressed, and the life of the movable partitions 114 and 115 can be extended.

図８は、本発明の実施例に係る蓄電池システムにおける蓄電池温度と周囲温度に応じた可動仕切りの状態説明図である。 FIG. 8 is an explanatory diagram of the state of the movable partition according to the storage battery temperature and the ambient temperature in the storage battery system according to the embodiment of the present invention.

図８において、送風装置１０２を運転して蓄電池１０１の温度Ｔ１（℃）と周囲温度Ｔ２（℃）を計測したところ、可動仕切り１１４、１１５が「閉」の場合、蓄電池１０１の温度Ｔ１が、第１の蓄電池温度閾値ｔｈ１より低い第２の蓄電池温度閾値ｔｈ２以下であれば、周囲温度Ｔ２を、設定された周囲温度領域Ａ３内に保持できる結果が得られた。一方、蓄電池１０１の温度Ｔ１が、第１の蓄電池温度閾値ｔｈ１を超えた場合、可動仕切り１１４、１１５を「開」にすることで、筐体１０３内に外気が導入されるので、周囲温度Ｔ２を、設定された周囲温度領域Ａ５内に保持できる結果が得られた。 In FIG. 8, when the temperature T1 (° C.) and the ambient temperature T2 (° C.) of the storage battery 101 are measured by operating the blower 102, when the movable partitions 114 and 115 are "closed", the temperature T1 of the storage battery 101 is determined. When the temperature is equal to or less than the second storage battery temperature threshold th2, which is lower than the first storage battery temperature threshold th1, the result is obtained that the ambient temperature T2 can be kept within the set ambient temperature region A3. On the other hand, when the temperature T1 of the storage battery 101 exceeds the first storage battery temperature threshold th1, the outside air is introduced into the housing 103 by opening the movable partitions 114 and 115, so that the ambient temperature T2 Was obtained in the set ambient temperature range A5.

また、蓄電池１０１の温度Ｔ１が、第２の蓄電池温度閾値ｔｈ２を超えても、第１の蓄電池温度閾値ｔｈ１以下であれば、以下の設定条件に応じて、可動仕切り１１４、１１５を「閉」または「開」の状態にしても、周囲温度Ｔ２を、設定された周囲温度領域Ａ４（周囲温度領域Ａ３と周囲温度領域Ａ５との間の領域）内に保持できる結果が得られた。 Further, even if the temperature T1 of the storage battery 101 exceeds the second storage battery temperature threshold th2, if it is equal to or less than the first storage battery temperature threshold th1, the movable partitions 114 and 115 are "closed" according to the following setting conditions. Alternatively, even in the "open" state, the result was obtained that the ambient temperature T2 could be maintained within the set ambient temperature region A4 (the region between the ambient temperature region A3 and the ambient temperature region A5).

具体的には、第１の設定条件として、送風装置１０２の風量を１００％に設定し、可動仕切り１１４、１１５を「開」の状態に設定した場合、蓄電池１０１の温度Ｔ１を、第１の蓄電池温度閾値ｔｈ１より高い、周囲温度領域Ａ５内に保持することができる。 Specifically, as the first setting condition, when the air volume of the blower 102 is set to 100% and the movable partitions 114 and 115 are set to the "open" state, the temperature T1 of the storage battery 101 is set to the first. It can be kept in the ambient temperature region A5, which is higher than the storage battery temperature threshold th1.

第２の設定条件として、送風装置１０２の風量を１００％に設定し、可動仕切り１１４、１１５を「閉」の状態に設定した場合、蓄電池１０１の温度Ｔ１を、第２の蓄電池温度閾値ｔｈ２以下となる、周囲温度領域Ａ３内に保持することができると共に、外気温（周囲温度）と蓄電池１０１の温度Ｔ１との温度差を、第１の蓄電池温度閾値ｔｈ１以上に保持することができる。 As the second setting condition, when the air volume of the blower 102 is set to 100% and the movable partitions 114 and 115 are set to the "closed" state, the temperature T1 of the storage battery 101 is set to the second storage battery temperature threshold th2 or less. It can be maintained in the ambient temperature region A3, and the temperature difference between the outside air temperature (ambient temperature) and the temperature T1 of the storage battery 101 can be maintained at the first storage battery temperature threshold th1 or higher.

第３の設定条件として、送風装置１０２の風量を０〜９９％に設定し、可動仕切り１１４、１１５を「閉」の状態に設定した場合、蓄電池１０１の温度Ｔ１を、第２の蓄電池温度閾値ｔｈ２以下となる、周囲温度領域Ａ３内に保持することができる。 As the third setting condition, when the air volume of the blower 102 is set to 0 to 99% and the movable partitions 114 and 115 are set to the "closed" state, the temperature T1 of the storage battery 101 is set to the second storage battery temperature threshold value. It can be kept in the ambient temperature region A3, which is th2 or less.

なお、第１の設定条件の場合、可動仕切り１１４、１１５が「開」の状態にあるので、送風装置１０２の運転に伴う騒音レベルが許容値を超えることはあるが、第２の設定条件及び第３の設定条件の場合、可動仕切り１１４、１１５が「閉」の状態にあるので、送風装置１０２の運転に伴う騒音レベルを許容値よりも低いレベルに保持することが可能である。 In the case of the first setting condition, since the movable partitions 114 and 115 are in the "open" state, the noise level due to the operation of the blower device 102 may exceed the permissible value, but the second setting condition and In the case of the third setting condition, since the movable partitions 114 and 115 are in the “closed” state, it is possible to keep the noise level associated with the operation of the blower device 102 at a level lower than the permissible value.

上記結果から、蓄電池システムを適用する上位システムにおいて求められる、蓄電池の温度、騒音レベル、及び蓄電池温度ばらつきが、それぞれの許容値を超えるのを防止するように、可動仕切り１１４、１１５の開閉と送風装置１０２の運転を制御することができ、結果として、各蓄電池１０１の温度を、周囲温度領域Ａ３〜Ａ５内に保持することができる。 From the above results, the movable partitions 114 and 115 are opened and closed and blown so as to prevent the storage battery temperature, noise level, and storage battery temperature variation required in the host system to which the storage battery system is applied from exceeding their respective allowable values. The operation of the device 102 can be controlled, and as a result, the temperature of each storage battery 101 can be kept within the ambient temperature ranges A3 to A5.

本実施例によれば、蓄電池を収納する筐体への外気の導入と導入遮断を筐体内外の状況に応じて選択することができ、結果として、蓄電池の温度上昇を抑制し、蓄電池の性能を長期間維持することができる。 According to this embodiment, the introduction of outside air into the housing for storing the storage battery and the interruption of the introduction can be selected according to the situation inside and outside the housing, and as a result, the temperature rise of the storage battery is suppressed and the performance of the storage battery is suppressed. Can be maintained for a long period of time.
