Description

本発明は、バッテリパックに関し、特に、バッテリパックの熱を排出する放熱システムを有し、電気自動車など大きな電力が必要な装置へ適用する、冷却システムを有するバッテリパックに関する。   The present invention relates to a battery pack, and more particularly, to a battery pack having a cooling system that has a heat dissipation system that discharges heat from the battery pack and is applied to a device that requires large electric power such as an electric vehicle.

電気自動車は、電動駆動車両とも呼ばれ、１つ以上の電動モータを駆動システムの移動車両として使用する。電気自動車は、ガソリンなどの石油を燃やして得られるエネルギを利用して移動する交通手段と異なり、推進力に電気を利用するため、廃ガスが発生することを防ぐとともに騒音を小さくすることができる。
過去数十年の間に、石油エネルギを利用した交通手段が環境に与える悪影響から、電気を利用した交通手段が注目されている。電気自動車が利用する電気は、多くのエネルギ源（例えば、化石燃料、原子力、潮汐エネルギ、ソーラエネルギ、風力又はそれらの組合せからなる再生エネルギ）を利用して発生させることができる。 An electric vehicle, also called an electrically driven vehicle, uses one or more electric motors as a moving vehicle for the drive system. Unlike electric vehicles that use energy obtained by burning petroleum such as gasoline, electric vehicles use electricity for propulsion, thus preventing waste gas generation and reducing noise. .
In the past several decades, transportation using electricity has attracted attention due to the negative effects of transportation using petroleum energy on the environment. The electricity used by the electric vehicle can be generated using many energy sources (for example, fossil fuel, nuclear power, tidal energy, solar energy, wind energy, or a combination of these and other renewable energy).

現在、電気自動車又はハイブリッド電気自動車は次第に普及している。現在の電気自動車（Ｅｌｅｃｔｒｉｃ Ｖｅｈｉｃｌｅ：ＥＶ）及びハイブリッド電気自動車（Ｈｙｂｒｉｄ Ｅｌｅｃｔｒｉｃ Ｖｅｈｉｃｌｅ：ＨＥＶ）の大部分は、ニッケル水素（Ｎｉ−ＭＨ）二次電池を電源として使用しており、近年ではリチウムイオン二次電池も使用され始めている。
これらの二次電池は、高出力及び高容量でなければならないため、小型二次電池（バッテリユニット）は、直列接続又は並列接続により互いに接続されてバッテリモジュールに形成されているものがほとんどである。またバッテリモジュールは、直列接続方式又は並列接続方式によりそれぞれ互いに接続されて１つのバッテリパックに形成されているものがほとんどである。 Currently, electric vehicles or hybrid electric vehicles are becoming increasingly popular. Most of current electric vehicles (EV) and hybrid electric vehicles (HEV) use a nickel-hydrogen (Ni-MH) secondary battery as a power source. Batteries are also starting to be used.
Since these secondary batteries must have high output and high capacity, most of the small secondary batteries (battery units) are connected to each other by series connection or parallel connection and formed into a battery module. . Most of the battery modules are connected to each other by a series connection method or a parallel connection method and formed in one battery pack.

しかし高出力、高容量のバッテリパックを充放電させると非常に多くの熱が発生することがある。もし充放電による熱を効果的に放出させることができない場合、バッテリユニットの電気が速やかに使い果たされてしまう。そのため、放熱システムを有するバッテリパックが求められていた。   However, when a high-power, high-capacity battery pack is charged and discharged, a great amount of heat may be generated. If the heat due to charging / discharging cannot be effectively released, the electricity of the battery unit will be used up quickly. Therefore, a battery pack having a heat dissipation system has been demanded.

ハイブリッド電気自動車がバッテリパックによりモータを駆動する場合、放熱は非常に重要である。もし放熱が十分でない場合、バッテリユニットから発生される熱により、バッテリユニットの温度が変化し、バッテリユニットの内部温度が上昇して最悪の場合、爆発することもある。   When a hybrid electric vehicle drives a motor with a battery pack, heat dissipation is very important. If the heat radiation is not sufficient, the temperature of the battery unit changes due to the heat generated from the battery unit, the internal temperature of the battery unit rises, and in the worst case, the battery unit may explode.

ハイブリッド電気自動車のバッテリモジュールは、高電流により充放電を行い、充電式電池の内部反応により発生する熱により機能が低下する虞があった。   The battery module of the hybrid electric vehicle is charged / discharged by a high current, and there is a risk that the function is deteriorated by heat generated by an internal reaction of the rechargeable battery.

図１を参照する。図１に示すように、特許文献１の充電式バッテリモジュール１０は、複数のバッテリユニット１１と、ハウジング１２と、を含む。ハウジング１２には、バッテリユニット１１と、ハウジング１２内の温度を制御する冷却剤（矢印で示す）とが収納される。バッテリユニット１１は、注入される冷却剤に対して所定角度で傾けられた状態でハウジング１２中に配置される。
バッテリユニット１１は、所定の間隔でハウジング１２中に配列されてセル直列接続１３が形成される。ハウジング１２には、バッテリユニット１１の温度を調整する空気を流入させる入口１４が一側に設けられ、バッテリユニット１１の傍を通った空気を排出させる出口１５が他側に設けられている。しかし、バッテリユニット１１の間隔が小さくなりすぎて冷却剤が循環しなくなることを防ぐために、充電式バッテリモジュール１０の寸法が制限を受けるため小型化させることはできなかった。 Please refer to FIG. As shown in FIG. 1, the rechargeable battery module 10 of Patent Document 1 includes a plurality of battery units 11 and a housing 12. The housing 12 houses a battery unit 11 and a coolant (indicated by an arrow) that controls the temperature in the housing 12. The battery unit 11 is disposed in the housing 12 while being inclined at a predetermined angle with respect to the coolant to be injected.
The battery units 11 are arranged in the housing 12 at a predetermined interval to form a cell series connection 13. The housing 12 is provided with an inlet 14 through which air for adjusting the temperature of the battery unit 11 is introduced on one side, and an outlet 15 through which the air passing by the battery unit 11 is discharged is provided on the other side. However, in order to prevent the interval between the battery units 11 from becoming too small and the coolant from being circulated, the size of the rechargeable battery module 10 is limited and cannot be reduced in size.

図２を参照する。図２に示すように、特許文献２のバッテリは、冷却バッテリパックの空気を流すために用いる、空気入口部分に取り付けられたダブル濾過装置を有する。ダブル濾過装置は、大きめの気孔を有するプレフィルタと、小さめの気孔を有する中置濾過装置（ｍｅｄｉｕｍ ｆｉｌｔｅｒ）と、を含む。前置濾過装置は、頻繁に置き換えられるが、中置濾過装置はあまり置き換えられない。空気の流動方向から見た場合、プレフィルタが中置濾過装置の前に設置されているため、空気の埃を取り除いてバッテリパックの放熱効率を高めることができる。しかしこの構造の場合、バッテリパックの寸法を小型化することができなかった。   Please refer to FIG. As shown in FIG. 2, the battery of Patent Document 2 has a double filtration device attached to an air inlet portion that is used to flow air from a cooling battery pack. The double filtration device includes a pre-filter having larger pores and an in-medium filter having smaller pores. Pre-filtering devices are frequently replaced, but in-situ filtering devices are not so often replaced. When viewed from the air flow direction, the pre-filter is installed in front of the in-situ filtration device, so that air dust can be removed to increase the heat dissipation efficiency of the battery pack. However, in the case of this structure, the size of the battery pack cannot be reduced.

そのため、小型で高効率の放熱システムを有し、内部構造の強度が高いバッテリパックが求められていた。   Therefore, a battery pack having a small and highly efficient heat dissipation system and a high strength of the internal structure has been demanded.

（第１実施形態）
図３〜図５を参照する。図３は、本発明の第１実施形態に係るバッテリパックのハウジングを示す斜視図である。図４は、本発明の第１実施形態に係るハウジングがない状態のバッテリパックを示す分解斜視図である。図５は、本発明の第１実施形態に係る熱伝導棒を示す模式図である。図３〜図５に示すように、ハウジング１０３上には複数のねじ１０３１が設けられる。ねじ１０３１の機能については以下詳説する。 (First embodiment)
Please refer to FIG. FIG. 3 is a perspective view showing the housing of the battery pack according to the first embodiment of the present invention. FIG. 4 is an exploded perspective view showing the battery pack without the housing according to the first embodiment of the present invention. FIG. 5 is a schematic diagram showing the heat conducting rod according to the first embodiment of the present invention. As shown in FIGS. 3 to 5, a plurality of screws 1031 are provided on the housing 103. The function of the screw 1031 will be described in detail below.

図４を参照する。図４に示すように、バッテリパック１００は、複数のバッテリユニット１０１と、複数の熱伝導棒１０２と、２つの固定ユニット１０４と、を有する。バッテリユニット１０１のそれぞれは、互いに直列接続されるか並列接続されて平面上に配置され電気供給の基本ユニットを構成する。
熱伝導棒１０２について容易に理解できるように、以下図５に基づいて説明する。熱伝導棒１０２は、４つの側壁１０２５及び両端部１０２１を有する。図４及び図５に示すように、熱伝導棒１０２は、バッテリユニット１０１中に配置され、側壁１０２５とバッテリユニット１０１とが実質接触される。即ち、各側壁１０２５は、バッテリユニット１０１と接触され、第１実施形態の熱伝導棒１０２は、４つのバッテリユニット１０１により囲まれる。熱伝導棒１０２の熱は、両端部１０２１からバッテリユニット１０１の外部へ伝えられる。 Please refer to FIG. As shown in FIG. 4, the battery pack 100 includes a plurality of battery units 101, a plurality of heat conducting bars 102, and two fixed units 104. Each of the battery units 101 is connected in series with each other or connected in parallel and arranged on a plane to constitute a basic unit for supplying electricity.
The heat conductive rod 102 will be described below with reference to FIG. 5 so that it can be easily understood. The heat conducting rod 102 has four side walls 1025 and both end portions 1021. As shown in FIGS. 4 and 5, the heat conducting rod 102 is disposed in the battery unit 101, and the side wall 1025 and the battery unit 101 are substantially in contact with each other. That is, each side wall 1025 is in contact with the battery unit 101, and the heat conducting rod 102 of the first embodiment is surrounded by the four battery units 101. The heat of the heat conduction rod 102 is transmitted from both end portions 1021 to the outside of the battery unit 101.

ハウジング１０３は、バッテリユニット１０１及び熱伝導棒１０２を収納するために用い、熱伝導棒１０２の端部１０２１から外部環境へ熱を排出する。熱伝導棒１０２の端部１０２１は、ねじ１０３１が熱伝導棒１０２のねじ孔１０２２に螺入されてハウジング１０３と接続され、熱伝導棒１０２がハウジング１０３の内部支持構造として用いることにより、ハウジング１０３が外力により捻れたり変形したりすることを防ぐことができる。   The housing 103 is used to store the battery unit 101 and the heat conducting rod 102, and exhausts heat from the end 1021 of the heat conducting rod 102 to the external environment. The end portion 1021 of the heat conducting rod 102 is connected to the housing 103 by screwing a screw 1031 into the screw hole 1022 of the heat conducting rod 102, and the heat conducting rod 102 is used as an internal support structure of the housing 103. Can be prevented from being twisted or deformed by an external force.

ここで本発明の精神に基づき、注意すべき点を以下説明する。まず、熱伝導棒１０２は、端部１０２１だけによりハウジング１０３に接続される訳ではなく、バッテリパック１００が単層である場合、両端部１０２１をハウジング１０３へそれぞれ螺入させてもよい。言い換えると、ハウジング１０３が単層のバッテリパック１００に収納される方式のみに限定される訳ではなく、多層のバッテリパック１００を積層させてもよい。
固定ユニット１０４は、バッテリユニット１０１と熱伝導棒１０２とを固定して平面上に配置するために用いる。第１実施形態のバッテリユニット１０１には、一次電池が用いられているが、勿論、充電式電池を用いてもよい。熱伝導棒１０２は、熱伝導性材料からなってもよい。熱伝導性材料は、一般に金属又は合金であり、第１実施形態ではアルミニウムが使用されている。ハウジング１０３は、熱伝導棒１０２と同様、熱伝導性材料からなってもよい。また、この熱伝導性材料は、熱伝導棒１０２と同様にアルミニウムであってもよい。 Here, points to be noted based on the spirit of the present invention will be described below. First, the heat conducting rod 102 is not connected to the housing 103 only by the end portion 1021, but when the battery pack 100 is a single layer, both end portions 1021 may be screwed into the housing 103. In other words, the housing 103 is not limited to the method of being housed in the single-layer battery pack 100, and the multilayer battery pack 100 may be stacked.
The fixing unit 104 is used to fix the battery unit 101 and the heat conducting rod 102 and arrange them on a plane. Although the primary battery is used for the battery unit 101 of 1st Embodiment, of course, you may use a rechargeable battery. The heat conductive rod 102 may be made of a heat conductive material. The heat conductive material is generally a metal or an alloy, and aluminum is used in the first embodiment. The housing 103 may be made of a heat conductive material like the heat conductive rod 102. In addition, the heat conductive material may be aluminum like the heat conductive rod 102.

固定ユニット１０４は、絶縁体である。第１実施形態の絶縁体はプラスチックからなる。プラスチックを使用する目的は、バッテリユニット１０１に漏電が発生したり、直列接続／並列接続されたニッケル片（ｎｉｃｋｅｌ ｐｌａｔｅ）とハウジング１０３との間にショートが発生したりすることを防ぐことにある。   The fixed unit 104 is an insulator. The insulator of the first embodiment is made of plastic. The purpose of using the plastic is to prevent the battery unit 101 from being leaked, or from being short-circuited between the nickel plate (nickel plate) connected in series / parallel and the housing 103.

（第２実施形態）
第１実施形態の熱伝導棒１０２は、中実部材であり、ネジを螺入するねじ孔が両端部１０２１に設けられているが、勿論、中空状にしてもよい。 (Second Embodiment)
The heat conducting rod 102 of the first embodiment is a solid member, and screw holes into which screws are screwed are provided in both end portions 1021, but of course, it may be hollow.

図６を参照する。図６は、本発明の第２実施形態に係る概念図である。図６に示すように、第２実施形態は、第１実施形態と略同じであるが、熱伝導棒１０２が中空状である点で異なる。第２実施形態の熱伝導棒１０２は、中に貫設されたチャネル１０２６（点線で表示する）を有する。
ポンプ１０２７及び２本のパイプ１０２８，１０２９により循環系統が形成される。この循環系統は、熱伝導棒１０２のチャネル１０２６の一端部１０２１から他端部へ冷却液を流して熱伝導を高速化させる。第２実施形態では水が冷却液として用いられ、その循環方向は図６の矢印方向である。しかし他の実施形態では、エタノール、エチレングリコール又はオイルを冷却液として用いてもよい。 Please refer to FIG. FIG. 6 is a conceptual diagram according to the second embodiment of the present invention. As shown in FIG. 6, the second embodiment is substantially the same as the first embodiment, but differs in that the heat conducting rod 102 is hollow. The heat conducting rod 102 of the second embodiment has a channel 1026 (indicated by a dotted line) penetrated therein.
A circulation system is formed by the pump 1027 and the two pipes 1028 and 1029. In this circulation system, the coolant is flowed from one end 1021 of the channel 1026 of the heat conducting rod 102 to the other end so as to speed up the heat conduction. In the second embodiment, water is used as the coolant, and the circulation direction is the arrow direction in FIG. However, in other embodiments, ethanol, ethylene glycol or oil may be used as the coolant.

本発明の精神に基づき、熱伝導棒１０２は、必ずしも循環系統に接続する必要はない。本実施形態の熱伝導棒１０２は、循環系統に接続されるが、第１実施形態と同様に、ねじ１０３１を介してハウジング１０３に接続され、ハウジング１０３を内部から十分に支持してもよい。   Based on the spirit of the present invention, the heat conducting rod 102 need not necessarily be connected to the circulation system. Although the heat conducting rod 102 of the present embodiment is connected to the circulation system, it may be connected to the housing 103 via the screw 1031 and sufficiently support the housing 103 from the inside as in the first embodiment.

（第３実施形態）
図７及び図８を参照する。図７は、本発明の第３実施形態に係るバッテリパック中の熱伝導棒を示す断面図である。図８は、本発明の第３実施形態に係るバッテリパック中の他の熱伝導棒を示す断面図である。図７及び図８に示すように、第３実施形態の側壁１０２５の数は、第１実施形態の熱伝導棒１０２に周設されたバッテリユニット１０１の数に等しい。側壁１０２５の形状は、バッテリユニット１０１が熱伝導棒１０２に接触する箇所の形状と一致する。 (Third embodiment)
Please refer to FIG. 7 and FIG. FIG. 7 is a cross-sectional view showing a heat conducting rod in a battery pack according to the third embodiment of the present invention. FIG. 8 is a cross-sectional view showing another heat conducting rod in the battery pack according to the third embodiment of the present invention. As shown in FIGS. 7 and 8, the number of side walls 1025 in the third embodiment is equal to the number of battery units 101 provided around the heat conducting rod 102 in the first embodiment. The shape of the side wall 1025 matches the shape of the location where the battery unit 101 contacts the heat conducting rod 102.

類似の機能を有する部分には同一の符号が付してあり、ここでは詳しく述べない。図７は、本発明の第３実施形態に係るバッテリパック中の熱伝導棒を示す断面図である。図７に示すように、第３実施形態の熱伝導棒１０２は、正方形の断面を有する第１実施形態の熱伝導棒１０２と異なり、六角形の断面を有して６つのバッテリユニット１０１と接触される。熱伝導棒１０２は、バッテリユニット１０１の熱をバッテリユニット１０１から効果的に排出させるために用いる。
熱伝導棒１０２の断面形状は、熱伝導棒１０２に周設されたバッテリユニット１０１の数に応じて決定されるが、側壁の数は、第３実施形態に示すように、熱伝導棒１０２に周設されたバッテリユニット１０１の数だけに限定される訳ではない。例えば、バッテリユニット１０１が積層されている場合、２つ又は３つ以上のバッテリユニット１０１を同一の側壁１０２５に接触させてもよい。 Parts having similar functions are denoted by the same reference numerals and will not be described in detail here.
