Description

本考案はバッテリモジュールに関し、特に熱伝導接続部品でバッテリセルの熱平衡を行うバッテリモジュールを指す。 TECHNICAL FIELD The present invention relates to a battery module, and more particularly to a battery module with heat-conducting connecting parts for thermal balancing of battery cells.

近年、環境保護、二酸化炭素削減の需要に伴い、電気自動車が次第に人々の支持を集めている。多くの自動車メーカが、電気自動車市場で商機を得るため、続々と電気自動車の開発に参入している。電気自動車の動力源は、リチウムバッテリなどのバッテリである。電気自動車のバッテリ駆動力を高めるため、電気自動車には通常相当数のバッテリセルを有するバッテリモジュールが設置され、電気自動車で使用するための十分な電力を提供する。 In recent years, with the demand for environmental protection and carbon dioxide reduction, electric vehicles have gradually gained popularity among people. Many automobile manufacturers are entering the development of electric vehicles one after another in order to seize business opportunities in the electric vehicle market. Electric vehicles are powered by batteries, such as lithium batteries. In order to increase the battery driving power of electric vehicles, electric vehicles are usually installed with battery modules having a number of battery cells to provide sufficient power for use in the electric vehicles.

図１、図２及び図３を参照されたい。図１、図２及び図３は慣用されるバッテリモジュールの上面断面図、正面断面図及び側面断面図である。図１、図２及び図３に示すように、バッテリモジュール１００は筐体１１、複数のバッテリセル１３、第１ホルダ１３１及び第２ホルダ１３２を含む。これらのバッテリセル１３は第１ホルダ１３１及び第２ホルダ１３２の間に収容及び固定され、これらのバッテリセル１３を備え付けた第１ホルダ１３１及び第２ホルダ１３２は筐体１１中に配置され、筐体１１がバッテリセル１３並びに第１ホルダ１３１及び第２ホルダ１３２を保護する。従来の第１ホルダ１３１及び第２ホルダ１３２の本体は通常細長い形状に設計され、該バッテリセル１３はそれぞれ第１ホルダ１３１及び第２ホルダ１３２の間に水平方向に同じ高さで配列される。 See FIGS. 1, 2 and 3. FIG. 1, 2 and 3 are top sectional view, front sectional view and side sectional view of a conventional battery module. As shown in FIGS. 1, 2 and 3, the battery module 100 includes a housing 11, a plurality of battery cells 13, a first holder 131 and a second holder 132. As shown in FIG. These battery cells 13 are accommodated and fixed between a first holder 131 and a second holder 132, and the first holder 131 and the second holder 132 with these battery cells 13 are arranged in the housing 11, Body 11 protects battery cell 13 and first holder 131 and second holder 132 . The bodies of the conventional first holder 131 and second holder 132 are generally designed in an elongated shape, and the battery cells 13 are horizontally arranged at the same height between the first holder 131 and the second holder 132, respectively.

バッテリモジュール１００のバッテリセル１３が充放電するとき、発熱して温度が上昇する。バッテリセル１３の充放電で生じた熱を放熱するため、通常、筐体１１の両側にそれぞれ送風ファン１５１及び排風ファン１５３が設置される。バッテリセル１３を収容した第１ホルダ１３１及び第２ホルダ１３２は、送風ファン１５１及び排風ファン１５３の間に配置される。送風ファン１５１は外部の冷たい空気を筐体１１内部のバッテリセル１３がある位置に向かって送り、送られた冷たい空気は発熱したバッテリセル１３を通過した後、熱い空気になる。続いて、排風ファン１５３は熱い空気を抜き取り、熱い空気を外に排出する。送風ファン１５１が送風し、排風ファン１５３が熱い空気を抜き取ることにより、充放電で発熱したバッテリセル１３の温度を低下させることができる。 When the battery cells 13 of the battery module 100 are charged and discharged, they generate heat and their temperature rises. In order to dissipate heat generated by charging and discharging of the battery cell 13, a blower fan 151 and an exhaust fan 153 are usually installed on both sides of the housing 11, respectively. A first holder 131 and a second holder 132 containing the battery cells 13 are arranged between the blower fan 151 and the exhaust fan 153 . The blower fan 151 sends external cold air toward the position where the battery cell 13 is located inside the housing 11 , and the sent cold air becomes hot air after passing through the heated battery cell 13 . Subsequently, the exhaust fan 153 extracts the hot air and exhausts the hot air to the outside. Blower fan 151 blows air and exhaust fan 153 draws out hot air, so that the temperature of battery cell 13 generated by charging and discharging can be lowered.

さらに、従来の該バッテリセル１３は細長い形状の第１ホルダ１３１及び第２ホルダ１３２間に水平方向に同じ高さで配列されるため、送風ファン１５１が送る冷たい空気の大部分の風力は、いずれも送風ファン１５１から比較的近くにある前列のバッテリセル１３に遮られ、高い流動抵抗の現象が引き起こされる。少数の風力のみが前列のバッテリセル１３間の隙間を通過し、後列のバッテリセル１３に流動することができる。他に、第１ホルダ１３１及び第２ホルダ１３２の限られた空間範囲内に比較的多くのバッテリセル１３を備え付けるため、配列された各バッテリセル１３は互いの間の隙間が通常非常に小さく、これも高い流動抵抗の状況を引き起こし、冷たい空気がバッテリセル１３間を流動する効率が非常に悪くなる。そのため、送風ファン１５１が送った冷たい空気は、往々にして低い流動抵抗の場所しか流動することができず、例えば冷たい空気は往々にして送風ファン１５１の近くにある前列のバッテリセル１３並びに第１ホルダ１３１及び第２ホルダ１３２の外側に送られ、送風ファン１５１から離れた後列のバッテリセル１３又は比較的内側に配列されたバッテリセル１３は送られた冷たい空気をほとんど受けることができない。従って、送風ファン１５１から離れたバッテリセル１３は、充放電するとき、しばしば過温度の状態にある。過温度の状態のバッテリセル１３は容易に消耗する、又は爆発のリスクが潜んでおり、バッテリセル１３の使用寿命に影響を及ぼす。 Furthermore, since the conventional battery cells 13 are horizontally arranged at the same height between the elongated first and second holders 131 and 132, most of the wind force of the cold air sent by the blower fan 151 will eventually is also blocked by the front row battery cells 13 which are relatively close to the blower fan 151, causing a phenomenon of high flow resistance. Only a small amount of wind force can pass through the gaps between the battery cells 13 in the front row and flow to the battery cells 13 in the back row. In addition, since a relatively large number of battery cells 13 are installed within the limited space of the first holder 131 and the second holder 132, the gaps between the arranged battery cells 13 are usually very small, This also creates a situation of high flow resistance, making the flow of cold air between the battery cells 13 very inefficient. Therefore, the cold air sent by the blower fan 151 can often flow only in places with low flow resistance. The cold air sent to the outside of the holder 131 and the second holder 132 is hardly received by the battery cells 13 in the rear row away from the blower fan 151 or the battery cells 13 arranged relatively inward. Therefore, the battery cells 13 away from the blower fan 151 are often in an over temperature condition when charging and discharging. A battery cell 13 in an over-temperature state is easily exhausted or has a risk of explosion, which affects the service life of the battery cell 13 .

このほか、冷たい空気が送風ファン１５１から流入し、該冷たい空気は通過する各バッテリセル１３と熱交換を行う。従って、風向きの後部に位置するバッテリセル１３が受ける空気は前部のバッテリセル１３が熱交換を終えた後の空気である。従って、バッテリモジュール１００全体の内部における各バッテリセル１３の温度は送風ファン１５１からの位置の遠さに基づいて、次第に高くなる温度勾配を呈する。さらには風向きの後部に位置するバッテリセル１３の劣化速度は、風向きの前部に位置するバッテリセル１３よりはるかに速い。 In addition, cold air flows in from the blower fan 151 and exchanges heat with each battery cell 13 passing through. Therefore, the air received by the battery cells 13 located at the rear in the wind direction is the air after the battery cells 13 at the front have finished heat exchange. Therefore, the temperature of each battery cell 13 inside the entire battery module 100 presents a temperature gradient that gradually rises according to the distance from the blower fan 151 . Furthermore, the deterioration speed of the battery cells 13 positioned at the rear in the wind direction is much faster than the battery cells 13 positioned at the front in the wind direction.

本考案の目的は、筐体、バッテリホルダ、複数のバッテリセル及び線状の熱伝導接続部品を含むバッテリモジュールを提供することである。筐体内部の一側に送風口が設けられ、もう一側に排風口が設けられる。バッテリホルダは筐体の送風口及び排風口間に備え付けられ、複数のバッテリセルを収容及び固定するのに用いられる。熱伝導接続部品は各バッテリセルの本体に巻き付けられ、各バッテリセル及び隣接するバッテリセル間を接続する。そのため、バッテリモジュールのバッテリセルが充放電動作を行うとき、熱伝導接続部品が各バッテリセル及び隣接するバッテリセル間の熱伝導を助けることにより、バッテリセルの温度は熱平衡に達することができる。 SUMMARY OF THE INVENTION An object of the present invention is to provide a battery module including a housing, a battery holder, a plurality of battery cells and linear heat-conducting connecting parts.

As shown in FIGS. 4 and 5 , the battery module 300 of the present invention includes a housing 31 , a battery holder 33 and a plurality of battery cells 35 .

During charging and discharging of the battery module 300 , cold air enters the housing 31 through the air outlet of the air blower 311 and hot air is discharged through the air outlet of the exhaust device 312 .

バッテリホルダ３３は、第１ホルダ３３１及び第２ホルダ３３２を含む。第１ホルダ３３１及び第２ホルダ３３２はそれぞれソケット（図示せず）を含む。各バッテリセル３５の上端は第１ホルダ３３１のソケット中に嵌入させ、下端は第２ホルダ３３２のソケット中に嵌入させる。各バッテリセル３５は第１ホルダ３３１及び第２ホルダ３３２間に固定され、各バッテリセル３５は互いの間で間隔を保持することができる。 Battery holder 33 includes a first holder 331 and a second holder 332 . The first holder 331 and the second holder 332 each include a socket (not shown). The upper end of each battery cell 35 is fitted into the socket of the first holder 331 and the lower end is fitted into the socket of the second holder 332 . Each battery cell 35 is fixed between the first holder 331 and the second holder 332, and each battery cell 35 can maintain a gap between each other.

バッテリモジュール３００は、少なくとも１つの線状の熱伝導接続部品３７をさらに含む。熱伝導接続部品３７は、非導電材質又は絶縁処理した金属材質で製造されたものでよい。好ましくは、熱伝導接続部品３７はマグネットワイヤ又は熱伝導効果を備えるが、表面は導電しない線体である。熱伝導接続部品３７は各バッテリセル３５の本体に巻き付けられ、各バッテリセル３５及び隣接するバッテリセル３５間を接続する。 Battery module 300 further includes at least one linear heat-conducting connecting piece 37 . The heat-conducting connecting piece 37 may be made of a non-conductive material or an insulated metallic material. Preferably, the heat-conducting connecting piece 37 is a magnet wire or a wire with a heat-conducting effect but a non-conducting surface. A heat-conducting connecting piece 37 is wrapped around the body of each battery cell 35 and connects between each battery cell 35 and adjacent battery cells 35 .

本考案において、熱伝導接続部品３７はバッテリモジュール３００により該バッテリセル３５の熱平衡に用いられる。具体的に、各バッテリセル３５は熱伝導接続部品３７を介して隣接するバッテリセル３５と接続される。バッテリセル３５が充放電するとき、熱伝導接続部品３７を利用して充放電で生じた熱を隣接するバッテリセル３５に誘導し、バッテリセル３５間の熱交換を行い、該バッテリセル３５を熱平衡させることができる。 In the present invention, the heat-conducting connecting parts 37 are used for the thermal balance of the battery cells 35 by the battery module 300 . Specifically, each battery cell 35 is connected to an adjacent battery cell 35 via a heat-conducting connecting piece 37 . When the battery cells 35 are charged and discharged, the heat-conducting connecting parts 37 are used to induce the heat generated by the charging and discharging to the adjacent battery cells 35 to perform heat exchange between the battery cells 35 and keep the battery cells 35 in thermal equilibrium. can be made

さらに、線体を熱伝導接続部品３７とすると、多くの空間を占めることはなく、バッテリセル３５の間は元々の間隔をおおよそ維持することができ、元々流動することができる空気が完全に遮られるのを防止する。このほか、バッテリセル３５の本体に熱伝導接続部品３７を数周巻き付けることができ、熱伝導接続部品３７及びバッテリセル３５間の接触面積を増加させ、より多くの熱量を放出する。さらにはバッテリセル３５の充放電で生じた熱を、迅速に熱伝導接続部品３７を介して隣接するバッテリセル３５に誘導させることができ、熱伝導の効果を高めることにつながる。 Furthermore, if the wire body is the heat-conducting connecting piece 37, it does not take up much space, and the original spacing between the battery cells 35 can be roughly maintained, completely blocking the air that could originally flow. prevent being caught. In addition, the body of the battery cell 35 can be wrapped with the heat-conducting connecting piece 37 several times to increase the contact area between the heat-conducting connecting piece 37 and the battery cell 35 to release more heat. Furthermore, the heat generated by charging and discharging the battery cells 35 can be quickly induced to the adjacent battery cells 35 via the heat-conducting connection parts 37, leading to an enhanced heat conduction effect.

さらに、本考案のバッテリモジュール３００は放熱フィン３９をさらに含む。熱伝導接続部品３７の両端は、放熱フィン３９に接続される。バッテリセル３５の充放電で生じた熱は、熱伝導接続部品３７を経過して放熱フィン３９に伝導され、放熱フィン３９により放熱することもできる。好ましくは、放熱フィン３９は送風装置３１１の付近に設置され、送風装置３１１から放熱フィン３９に送風され、これにより放熱フィン３９の放熱効果を高める。 In addition, the battery module 300 of the present invention further includes heat dissipation fins 39 . Both ends of the heat-conducting connecting part 37 are connected to the heat-dissipating fins 39 . The heat generated by charging and discharging the battery cells 35 passes through the heat-conducting connection parts 37 and is conducted to the heat radiation fins 39 , and can also be radiated by the heat radiation fins 39 . Preferably, the heat radiating fins 39 are installed near the blower 311 , and the air is blown from the blower 311 to the heat radiating fins 39 to enhance the heat radiating effect of the heat radiating fins 39 .

ここで、本考案のバッテリモジュール３００において、熱伝導接続部品３７の設置により、風向きの後部に位置し、温度が比較的高いバッテリセル３５は、熱伝導接続部品３７を介して風向きの前部で、温度が比較的低いバッテリセル３５に熱伝導することができる。これにより該バッテリセル３５の間で熱平衡を維持し、一部のバッテリセル３５が充放電するときに過熱し、損傷が生じる、又は爆発のリスクが発生するのを防止し、バッテリモジュール３００の使用における安全性を高める。 Here, in the battery module 300 of the present invention, due to the installation of the heat-conducting connection parts 37, the battery cells 35 located at the rear in the wind direction and having a relatively high temperature are transferred to the front part in the wind direction through the heat-conduction connection parts 37. , can conduct heat to the battery cell 35 where the temperature is relatively low.
