（第１実施形態）

FIG. 1 shows a perspective view of a power supply device 100 according to this embodiment. The power supply device 100 includes a housing 1, a duct 2 and a fan 3. The housing 1 houses a battery stack 10 as a power supply component and an assembly 20 on the side thereof. FIG. 1 shows a state in which an upper lid, which is a part of the housing 1, is removed. FIG. 2 shows a perspective view of the assembly 20.

電池スタック１０は複数の電池セルを、互いに隙間を設けて積層したものである。   The battery stack 10 is formed by stacking a plurality of battery cells with a gap therebetween.

アセンブリ２０は、電池スタック１０の出力電圧を降圧するＤＣＤＣコンバータである。詳細には、一例として、さらにジャンクションボックス基板２１、ジャンクションボックス基板冷却用の複数のフィンを有する第１冷却器２２が、ＤＣＤＣコンバータを構成するＤＣＤＣコンバータ基板３１、ＤＣＤＣコンバータ基板冷却用の複数のフィンを有する第２冷却器３２の上方に設けられている。ジャンクションボックス基板２１には、端子が複数設けられており、電池スタック１０やＤＣＤＣコンバータの出力や入力の配線が端子に結線される。   The assembly 20 is a DCDC converter that steps down the output voltage of the battery stack 10. More specifically, as an example, the junction box substrate 21 and the first cooler 22 having a plurality of fins for cooling the junction box substrate are a DCDC converter substrate 31 forming a DCDC converter, and a plurality of fins for cooling the DCDC converter substrate. Is provided above the second cooler 32 having. The junction box substrate 21 is provided with a plurality of terminals, and the output and input wirings of the battery stack 10 and the DCDC converter are connected to the terminals.

図３、図４に、図１のＡ−Ａ’線に沿った電源装置１００の模式断面図を示す。図３、図４に示すように筐体１のダクト２側には第１通気孔４１が設けられており、ファン３側には第２通気孔４２が設けられている。また、第１通気孔４１には第１防水弁４３が設けられ、第２通気孔４２には第２防水弁４４が設けられている。図３、４には、第１防水弁４３および第２防水弁４４とこれらの近傍とを、作用を分かりやすくするよう、とくに模式的に示すが、第１防水弁４３および第２防水弁４４の実際の形状、配置および開閉の動作態様は限定されない。   3 and 4 are schematic cross-sectional views of the power supply device 100 taken along the line A-A′ in FIG. 1. As shown in FIGS. 3 and 4, a first ventilation hole 41 is provided on the duct 2 side of the housing 1, and a second ventilation hole 42 is provided on the fan 3 side. A first waterproof valve 43 is provided in the first ventilation hole 41, and a second waterproof valve 44 is provided in the second ventilation hole 42. In FIGS. 3 and 4, the first waterproof valve 43 and the second waterproof valve 44 and their vicinity are schematically shown in order to facilitate understanding of the operation. However, the first waterproof valve 43 and the second waterproof valve 44 are shown. The actual shape, arrangement, and operation mode of opening and closing of are not limited.

ファン３の回転方向が第１方向である場合、図３に点線の矢印で示すように、ファン３は、第２通気孔４２から遠ざかる向きに送風し、第１防水弁４３および第２防水弁４４が開状態となり、第１通気孔４１から第２通気孔４２に向かう方向に、冷却用の空気が流れる。   When the rotation direction of the fan 3 is the first direction, the fan 3 blows air in a direction away from the second ventilation hole 42 as indicated by a dotted arrow in FIG. 3, and the first waterproof valve 43 and the second waterproof valve 43. 44 is opened, and cooling air flows in the direction from the first ventilation hole 41 to the second ventilation hole 42.

ファン３の回転方向が第１方向の反対方向である第２方向である場合、図４に点線の矢印で示すように、ファン３は、第２通気孔４２に近づく向きに送風するが、第１防水弁４３および第２防水弁４４が閉状態となり、電源装置１００内に、冷却用の空気が流れない。   When the rotation direction of the fan 3 is the second direction which is the opposite direction to the first direction, the fan 3 blows air in a direction approaching the second ventilation hole 42, as indicated by a dotted arrow in FIG. The first waterproof valve 43 and the second waterproof valve 44 are closed, and cooling air does not flow into the power supply device 100.

図５にファン３の制御装置２００の機能ブロックを示す。制御装置２００は、制御装置２００の外部から情報を受け付ける入力部２０１と、入力部２０１が受け付ける情報に基づいて、ファン３の回転方向を決定する決定部２０２と、決定部２０２による決定結果に基づいてファン３を駆動する駆動部２０３とを備える。制御装置２００は、電源装置１００に設けられてもよいし、車両に搭載される他の装置に設けられてもよい。またファン３の駆動電力は、典型的には車両に搭載される他の電源装置から提供されるが、電池スタック１０から提供されてもよい。   FIG. 5 shows a functional block of the control device 200 of the fan 3. The control device 200 includes an input unit 201 that receives information from the outside of the control device 200, a determination unit 202 that determines the rotation direction of the fan 3 based on the information that the input unit 201 receives, and a determination result by the determination unit 202. And a drive unit 203 that drives the fan 3. Control device 200 may be provided in power supply device 100, or may be provided in another device mounted on the vehicle. Further, the drive power of the fan 3 is typically provided from another power supply device mounted on the vehicle, but may be provided from the battery stack 10.

入力部２０１は、車両に設置された浸水センサや、浸水センサを備える他のＥＣＵと呼ばれる制御装置から、車両への浸水が発生したことを表す情報を受け取ることができる。浸水センサは例えば、電源装置１００の近くに設けられるものであってもよいし、車両の各部にそれぞれ設けられるものであってもよい。これにより、入力部２０１は、車両の少なくとも一部に浸水が発生し、電源装置１００内にも浸水するおそれがある場合に、これを表す情報を適宜受け付けることができる。   The input unit 201 can receive information indicating that water has infiltrated the vehicle from a water immersion sensor installed in the vehicle or a control device called another ECU including the water immersion sensor. The water immersion sensor may be provided, for example, near the power supply device 100, or may be provided in each part of the vehicle. Thereby, when the water is generated in at least a part of the vehicle and there is a risk that the power supply device 100 is also water-immersed, the input unit 201 can appropriately receive information indicating this.

決定部２０２は、入力部２０１が車両への浸水が発生したことを表す情報を受け付けていない場合、ファン３の回転方向を第１方向とすることを決定する。また、決定部２０２は、入力部２０１が車両への浸水が発生したことを表す情報を受け付けた場合、これに基づいて浸水を検知し、ファン３の回転方向を第２方向とすることを決定する。   When the input unit 201 does not receive the information indicating that the vehicle has been flooded, the determining unit 202 determines that the rotation direction of the fan 3 is the first direction. Further, when the input unit 201 receives the information indicating that the vehicle has been flooded, the determination unit 202 detects the flooding based on the information and determines that the rotation direction of the fan 3 is the second direction. To do.

駆動部２０３は、決定部２０２が決定した回転方向に対応した駆動信号あるいは駆動電力をファン３に供給する。   The drive unit 203 supplies the fan 3 with a drive signal or drive power corresponding to the rotation direction determined by the determination unit 202.

なお、制御装置２００の入力部２０１は、例えば電源装置１００内に設けられた温度センサから温度を表す情報を受け付け、決定部２０２はこれに基づいて、第１方向におけるファン３の送風強度を決定してもよい。例えば入力部２０１が受け付けた情報が表わす温度が高いほど、送風強度をファン３の性能の範囲内で大きくし、温度が所定値以下であれば、送風強度を０（送風停止）としてもよい。この場合、駆動部２０３は、回転方向および送風強度に対応した駆動信号あるいは駆動電力をファン３に供給する。   Note that the input unit 201 of the control device 200 receives information indicating the temperature from, for example, a temperature sensor provided in the power supply device 100, and the determination unit 202 determines the blowing intensity of the fan 3 in the first direction based on the information. You may. For example, the higher the temperature indicated by the information received by the input unit 201, the larger the air blowing intensity within the range of the performance of the fan 3, and if the temperature is equal to or lower than a predetermined value, the air blowing intensity may be set to 0 (air blowing stopped). In this case, the drive unit 203 supplies the fan 3 with a drive signal or drive power corresponding to the rotation direction and the blowing intensity.

制御装置２００の以上のような動作によって、ファン３は、車両への浸水が発生していない場合は、電源装置１００の冷却ファンとしての機能を有し、車両への浸水が発生した場合は、防水弁を閉状態にして、電源装置１００への浸水を抑止し、電池スタック１０の漏電、破損を防止する機能を有する。このように本実施形態においては、ファン３の送風機能を、冷却だけでなく防水弁の駆動に利用して高機能化することができる。   By the above operation of the control device 200, the fan 3 has a function as a cooling fan of the power supply device 100 when the vehicle is not flooded, and when the vehicle is flooded, The waterproof valve is closed to prevent water from entering the power supply device 100 and prevent the battery stack 10 from leaking or being damaged. As described above, in the present embodiment, the air blowing function of the fan 3 can be used not only for cooling but also for driving the waterproof valve, so that the fan 3 can be made highly functional.

（第２実施形態）
図６、図７に、本実施形態に係る電源装置１００の模式断面図を示す。本実施形態は、電源装置１００が防水弁を備えない点、および制御装置２００の処理が異なる点で第１実施形態と異なる。 (Second embodiment)
6 and 7 are schematic cross-sectional views of the power supply device 100 according to this embodiment. The present embodiment is different from the first embodiment in that the power supply device 100 does not include a waterproof valve and the process of the control device 200 is different.

ファン３の回転方向が第１方向である場合、図６に点線の矢印で示すように、ファン３は、第２通気孔４２から遠ざかる向きに送風し、第１通気孔４１から第２通気孔４２に向かう方向に、冷却用の空気が流れる。   When the rotation direction of the fan 3 is the first direction, the fan 3 blows air in a direction away from the second ventilation hole 42 as shown by a dotted arrow in FIG. Cooling air flows in the direction toward 42.

ファン３の回転方向が第１方向の反対方向である第２方向である場合、図７に点線の矢印で示すように、ファン３は、第２通気孔４２に近づく向きに送風し、第２通気孔４２から第１通気孔４１に向かう方向に、冷却用の空気が流れる。   When the rotation direction of the fan 3 is the second direction, which is the opposite direction to the first direction, the fan 3 blows air in a direction approaching the second ventilation hole 42 as shown by a dotted arrow in FIG. Cooling air flows in a direction from the ventilation hole 42 toward the first ventilation hole 41.

本実施形態では、電池スタック１０およびＤＣＤＣコンバータ（アセンブリ２０）には、それぞれ温度センサが設けられており、制御装置２００の入力部２０１は、各温度センサから電池スタック１０の温度を表す情報およびアセンブリ２０の温度を表す情報を受け付ける。   In the present embodiment, the battery stack 10 and the DCDC converter (assembly 20) are each provided with a temperature sensor, and the input unit 201 of the control device 200 includes information indicating the temperature of the battery stack 10 from each temperature sensor and the assembly. Information indicating the temperature of 20 is received.

決定部２０２は、入力部２０１が受け付けた情報に基づいて、電池スタック１０およびＤＣＤＣコンバータ（アセンブリ２０）の温度を判定し、ファン３の回転方向および送風強度を決定する。決定方法の一例を表１に示す。   The determination unit 202 determines the temperatures of the battery stack 10 and the DCDC converter (assembly 20) based on the information received by the input unit 201, and determines the rotation direction of the fan 3 and the blowing strength. Table 1 shows an example of the determination method.

Figure 2020079012
Figure 2020079012

表１に示すように、決定部２０２は、電池スタック１０の温度が第１所定値Ｔ１未満であり、かつ、ＤＣＤＣコンバータ（アセンブリ２０）の温度が第２所定値Ｔ２以上である場合、ファン３の回転方向を第２方向とし、これ以外の場合は、ファン３の回転方向を第１方向とする。また、決定部２０２は、電池スタック１０の温度が第１所定値Ｔ１未満であり、かつ、ＤＣＤＣコンバータ（アセンブリ２０）の温度が第２所定値Ｔ２未満である場合、ファン３の送風強度を「弱」とし、これ以外の場合は、ファン３の送風強度を「強」とする。なお、電池スタック１０の温度が第１所定値Ｔ１未満であり、かつ、ＤＣＤＣコンバータ（アセンブリ２０）の温度が第２所定値Ｔ２未満である場合、ファン３の送風強度を「無風」、すなわち回転停止としてもよい。   As shown in Table 1, when the temperature of the battery stack 10 is lower than the first predetermined value T1 and the temperature of the DCDC converter (assembly 20) is the second predetermined value T2 or higher, the determining unit 202 determines that the fan 3 Is the second direction, and in other cases, the rotation direction of the fan 3 is the first direction. Further, when the temperature of the battery stack 10 is lower than the first predetermined value T1 and the temperature of the DCDC converter (assembly 20) is lower than the second predetermined value T2, the determination unit 202 sets the blowing intensity of the fan 3 to " In other cases, the blowing strength of the fan 3 is set to "strong". When the temperature of the battery stack 10 is less than the first predetermined value T1 and the temperature of the DCDC converter (assembly 20) is less than the second predetermined value T2, the blowing intensity of the fan 3 is “no wind”, that is, rotation. It may be stopped.

駆動部２０３は、決定部２０２が決定した回転方向および送風強度に対応した駆動信号あるいは駆動電力をファン３に供給する。   The drive unit 203 supplies the fan 3 with a drive signal or drive power corresponding to the rotation direction and the blowing intensity determined by the determination unit 202.

制御装置２００の以上のような動作によって、ファン３は、電池スタック１０およびＤＣＤＣコンバータ（アセンブリ２０）の冷却バランスが取れる方向に送風を行う。電池スタック１０が比較的低温である場合、過度に冷却すると、電池の出力性能が劣化するおそれがある。そこで、とくに、ＤＣＤＣコンバータ（アセンブリ２０）の温度が比較的高く、電池スタック１０の温度が比較的低い場合は、送風の向きをＤＣＤＣコンバータ（アセンブリ２０）から電池スタック１０へ向かう向きとし、ＤＣＤＣコンバータ（アセンブリ２０）の熱を電池スタック１０に供給することで、電池スタック１０を過度に冷却しないようにして電池スタック１０の出力性能の劣化を抑止する。このように本実施形態においては、ファン３の送風機能を、電池スタック１０およびＤＣＤＣコンバータ（アセンブリ２０）の冷却バランスが取れるように利用して、高機能化することができる。   By the above-described operation of the control device 200, the fan 3 blows air in a direction in which the cooling balance of the battery stack 10 and the DCDC converter (assembly 20) can be maintained. When the battery stack 10 is at a relatively low temperature, excessive cooling may deteriorate the output performance of the battery. Therefore, particularly when the temperature of the DCDC converter (assembly 20) is relatively high and the temperature of the battery stack 10 is relatively low, the direction of air blowing is set to the direction from the DCDC converter (assembly 20) to the battery stack 10, and the DCDC converter is used. By supplying the heat of (assembly 20) to the battery stack 10, the battery stack 10 is prevented from being excessively cooled and the deterioration of the output performance of the battery stack 10 is suppressed. As described above, in the present embodiment, the air blowing function of the fan 3 can be used so that the cooling of the battery stack 10 and the DCDC converter (assembly 20) can be balanced, and the fan 3 can be made highly functional.

（効果）
本発明の効果をまとめると以下のとおりである。すなわち、本発明に係るファンの制御装置においては、所定の条件が成立していない場合に、ファンの回転方向を第１方向とし、所定の条件が成立した場合に、ファンの回転方向を第１方向と反対方向の第２方向とし、電源装置１００内の送風方向を反転させる。例えば、所定の条件として、車両への浸水を検出した場合に、ファンの送風方向を反転させ、防水弁を閉状態とすれば、電源装置１００内への浸水を抑止できる。また、所定の条件として、電池スタック１０の温度が比較的低温であり、ＤＣＤＣコンバータの温度が比較的高温である場合に、ファンの送風方向を反転させ、電池スタック１０およびＤＣＤＣコンバータの冷却バランスを取ることができる。このように、本発明によれば、従来に比べファン３の送風機能を活用して高機能化することができる。 (effect)

That is, in the fan control device according to the present invention, the rotation direction of the fan is set to the first direction when the predetermined condition is not satisfied, and the rotation direction of the fan is set to the first direction when the predetermined condition is satisfied. The air blowing direction in the power supply device 100 is reversed by setting the second direction opposite to the direction. For example, as a predetermined condition, when water ingress to the vehicle is detected, reversing the blowing direction of the fan and closing the waterproof valve can prevent ingress of water into the power supply device 100. In addition, as a predetermined condition, when the temperature of the battery stack 10 is relatively low and the temperature of the DCDC converter is relatively high, the air blowing direction of the fan is reversed to maintain the cooling balance of the battery stack 10 and the DCDC converter. Can be taken. As described above, according to the present invention, it is possible to utilize the air blowing function of the fan 3 to achieve higher functionality than ever before.
