本考案は、電気自動車のバッテリを効率良く使用する電気自動車のバッテリ装 置に関する。 The present invention relates to an electric vehicle battery device that efficiently uses the electric vehicle battery.
【０００２】[0002]
近年、脱石油資源、低公害化をめざして電動モータを走行駆動源とする電気自 動車、あるいは、内燃機関と電動モータとを組み合わせた電気自動車（いわゆる ハイブリッド自動車）等の車両の開発が進められており、この電気自動車の電源 であるバッテリ装置は、図９に示すように、車両内に、必要とされる電圧および 電気容量を有するバッテリ本体２を複数個配設しバッテリ集合体１を形成して搭 載している。 In recent years, the development of vehicles such as electric vehicles that use an electric motor as a drive source for traveling, and electric vehicles (so-called hybrid vehicles) that combine an internal combustion engine and an electric motor has been promoted with the aim of reducing oil resources and reducing pollution. As shown in FIG. 9, a battery device which is a power source of this electric vehicle forms a battery assembly 1 by disposing a plurality of battery bodies 2 having a required voltage and electric capacity in the vehicle. And is on board.
【０００３】 また、上記バッテリ集合体１を構成するバッテリ本体２は、例えばバッテリ本 体２が１２Ｖである場合、図８（ａ），（ｂ），（ｃ）に示すように、バッテリ ケース３と、このバッテリケース３内部端側に収納された２Ｖの端側単電池４ａ と、この端側単電池４ａ間に挟装された２Ｖの内側単電池４ｂとを備えている。 すなわち、図８（ａ）のバッテリ本体２ａでは、２つの端側単電池４ａと４つの 内側単電池４ｂとを一列に配列して直列接続し形成され、また、図８（ｂ）に示 すバッテリ本体２ｂでは、上記図８（ａ）のバッテリ本体２ａの電極が逆になる ように構成され、さらに、図８（ｃ）に示すバッテリ本体２ｃでは、４つの端側 単電池４ａと２つの内側単電池４ｂとを配列して直列接続し１２Ｖの電圧が得ら れるように形成されている。The battery main body 2 constituting the battery assembly 1 has a battery case 3 as shown in FIGS. 8A, 8B, and 8C when the battery main body 2 is 12V, for example. And a 2V end-side unit cell 4a housed inside the battery case 3 and an 2V inner-side unit cell 4b sandwiched between the end-side unit cells 4a. That is, in the battery body 2a of FIG. 8 (a), two end-side cells 4a and four inner cells 4b are arranged in a line and connected in series, and also shown in FIG. 8 (b). In the battery body 2b, the electrodes of the battery body 2a of FIG. 8 (a) are configured to be reversed, and further, in the battery body 2c shown in FIG. 8 (c), four end side unit cells 4a and two The inner cells 4b are arranged and connected in series so as to obtain a voltage of 12V.
【０００４】 ところで、バッテリ集合体では、充電あるいは放電が繰り返されると、個々の バッテリ本体が発熱して熱が蓄積され、上記バッテリ集合体の温度は次第に上昇 する。そして、温度が高くなり過ぎるとバッテリ本体の容量減少等バッテリ寿命 を短くするのみならず、電流を供給しても水の分解に消費され完全充電ができな くなる虞れがあり、バッテリの能力が十分に発揮できなくなり、さらに、バッテ リの自己放電も急速に大きくなる。このような問題に対処するため、特開昭４９ −１２７１３４号公報に示されるように、送風によりバッテリを冷却する様々な 技術が提案されている。By the way, in the battery assembly, when charging or discharging is repeated, the individual battery bodies generate heat to accumulate heat, and the temperature of the battery assembly gradually rises. If the temperature rises too high, not only will the battery life be reduced, such as a decrease in battery capacity, but also the supply of electric current may consume water to decompose water, making it impossible to fully charge the battery. Will not be fully exerted, and the self-discharge of the battery will rapidly increase. In order to deal with such a problem, various techniques for cooling the battery by blowing air have been proposed, as disclosed in Japanese Patent Laid-Open No. 49-127134.
【０００５】 一方、寒冷地等で周囲温度が極度に低下した場合には、バッテリ本体の能力低 下が生じるため、実開昭６１−１９３８４４号公報に示されるように、バッテリ 本体を暖める必要がある。On the other hand, when the ambient temperature is extremely lowered in a cold region or the like, the capacity of the battery main body is deteriorated. Therefore, as shown in Japanese Utility Model Laid-Open No. 61-193844, it is necessary to warm the battery main body. is there.
【０００６】[0006]
しかしながら、従来のバッテリ集合体は、限られた車両空間内にできるだけ多 くのバッテリ本体を密集し配列して構成されているため、バッテリ集合体の内側 に配設されたバッテリ本体は、バッテリ集合体の外側に配設されたバッテリ本体 に比べて熱交換が悪くなり、バッテリ本来の能力を十分に発揮できないばかりか 、外側に配設されたバッテリ本体と比較してバッテリ寿命が短くなってしまうと いった問題が生じる。 However, the conventional battery assembly is configured by arranging as many battery bodies as possible in a limited vehicle space so that the battery bodies arranged inside the battery assembly are The heat exchange becomes worse than that of the battery main body placed outside the body, and not only the original capacity of the battery cannot be fully exerted, but also the battery life becomes shorter than that of the battery main body placed outside. Such problems arise.
【０００７】 また、上述のように、バッテリ集合体を構成するバッテリ本体間で性能および 寿命等にばらつきが生じることにより、バッテリ装置に関する保守・点検のメン テナンス作業が複雑になるとともに、メンテナンスの頻度も多くなるという問題 が生じる。Further, as described above, the performance of the batteries, which constitute the battery assembly, and the variations in the service life thereof become different, which complicates the maintenance work for the maintenance and inspection of the battery device, and the frequency of maintenance. The problem is that there will be more.
【０００８】 本考案は上記事情に鑑みてなされたもので、バッテリ集合体を構成する複数個 のバッテリ本体間の熱交換のばらつきを、これら各バッテリ本体を構成する単電 池レベルで良好に均衡させることにより、上記各バッテリ本体の有する性能を十 分に発揮させるとともに、上記各バッテリ本体の寿命を向上させることができ、 また、メンテナンス性を向上させることのできる電気自動車のバッテリ装置を提 供することを目的としている。The present invention has been made in view of the above circumstances, and satisfactorily balances variations in heat exchange among a plurality of battery bodies forming a battery assembly at the level of a single battery forming each of these battery bodies. By so doing, the battery device of the electric vehicle can be provided in which the performance of each battery main body can be fully exhibited, the life of each battery main body can be extended, and the maintainability can be improved. Is intended.
【０００９】[0009]
上記目的を達成するため本考案による電気自動車のバッテリ装置は、バッテリ ケース内部端側に収納した端側単電池とこの端側単電池間に挟装した内側単電池 とを有するバッテリ本体を複数個配設してバッテリ集合体を形成した電気自動車 のバッテリ装置において、上記端側単電池のみ面した上記各バッテリケースの側 面同士を近接して連設するとともに、上記端側単電池と上記内側単電池とが面し た上記各バッテリケースの側面間に熱交換用間隙部を形成したものである。 In order to achieve the above object, a battery device for an electric vehicle according to the present invention comprises a plurality of battery bodies each having an end-side cell housed inside a battery case and an inner cell sandwiched between the end-side cells. In a battery device for an electric vehicle in which battery assemblies are formed by arranging the battery assemblies, the side surfaces of the battery cases facing only the end-side cells are connected in close proximity to each other, and the end-side cells and the inside A heat exchange gap is formed between the side faces of the battery cases facing the unit cells.
【００１０】[0010]
上記構成において、まず、バッテリ集合体を構成する複数個のバッテリ本体が 冷却される場合は、これら各バッテリ本体を構成する端側単電池と内側単電池と が面した各バッテリケースの側面間に形成された熱交換用間隙部から放熱され、 上記各バッテリ本体が冷却される。 また、上記端側単電池のみ面した上記各バッテリケースの側面同士は近接して 連設されているため、これら各バッテリケースの側面から放熱されることはなく 上記端側単電池と上記内側単電池との熱交換条件が略同一となる。 一方、上記各バッテリ本体が暖められる場合は、上述の冷却される場合とは逆 に、上記端側単電池と上記内側単電池とが面した上記各バッテリケースの側面間 に形成された上記熱交換用間隙部から受熱して、上記各バッテリ本体が暖められ る。 また、上記端側単電池のみ面した上記各バッテリケースの側面から受熱される ことはなく上記端側単電池と上記内側単電池との熱交換条件が略同一となる。 In the above configuration, first, when the plurality of battery bodies that form the battery assembly are cooled, the end-side cells and the inner cells that form these battery bodies are located between the side surfaces of the battery cases facing each other. Heat is dissipated from the formed heat exchange gaps, and the battery bodies are cooled. Further, since the side surfaces of each of the battery cases facing only the end-side unit cells are arranged in close proximity to each other, heat is not radiated from the side surfaces of each of the battery cases, and the end-side unit cells and the inside unit cells are not radiated. The heat exchange conditions with the battery are almost the same. On the other hand, when the respective battery bodies are warmed, the heat generated between the side surfaces of the battery cases facing the end-side unit cells and the inner-side unit cells is opposite to the case where the battery units are cooled. Each battery body is warmed by receiving heat from the replacement gap. Further, heat is not received from the side surface of each of the battery cases facing only the end-side unit cells, and the heat exchange conditions between the end-side unit cells and the inner-side unit cells are substantially the same.
【００１１】[0011]
以下、図面に基づいて本考案の実施例を説明する。 図１および図２は本考案の第一実施例を示し、図１は電気自動車に搭載したバ ッテリ集合体の斜視図、図２はバッテリ集合体の各バッテリ本体の内部説明図で ある。 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment of the present invention. FIG. 1 is a perspective view of a battery assembly mounted on an electric vehicle, and FIG. 2 is an internal explanatory view of each battery body of the battery assembly.
【００１２】 図中、符号１０は電気自動車を示し、この電気自動車１０には電源としてのバ ッテリ集合体１１が搭載されている。In the figure, reference numeral 10 indicates an electric vehicle, and a battery assembly 11 as a power source is mounted on the electric vehicle 10.
【００１３】 また、上記バッテリ集合体１１は、複数個のバッテリ本体２（例えば、電圧１ ２Ｖのもの）を縦横に配列して（本実施例では、車両の前後方向に５列、左右方 向（車幅方向）に４列として）構成されている。上記各バッテリ本体２は、電圧 １２Ｖの場合、前述の図８（ａ），（ｂ），（ｃ）に示すように、バッテリケー ス３と、このバッテリケース３内部端側に収納された２Ｖの端側単電池４ａと、 この端側単電池４ａ間に挟装された２Ｖの内側単電池４ｂとを備え、これら各単 電池４ａ，４ｂを直列接続して１２Ｖとなるように形成されている。Further, the battery assembly 11 has a plurality of battery bodies 2 (for example, with a voltage of 12V) arranged vertically and horizontally (in this embodiment, five rows in the front-rear direction of the vehicle, and left-right directions). 4 rows (in the vehicle width direction). When the voltage of each battery main body 2 is 12V, as shown in FIGS. 8 (a), 8 (b), and 8 (c), the battery case 3 and the 2V stored inside the battery case 3 are accommodated. End side unit cell 4a and 2V inner side unit cell 4b sandwiched between the end side unit cells 4a. These unit cells 4a and 4b are connected in series to form 12V. There is.
【００１４】 また、上記各バッテリ本体２は、車両の左右方向（車幅方向）、すなわち、上 記端側単電池４ａのみ面した上記各バッテリケース３の側面同士が近接して連設 されるとともに、車両の前後方向、すなわち、上記端側単電池４ａと上記内側単 電池４ｂとが面した上記各バッテリケース３の側面間に熱交換用間隙部１２が形 成されて配設されている。このため、図２（ａ），（ｂ）に示すように、上記各 単電池４ａ，４ｂの上記熱交換用間隙部１２に臨まされる面積が略同じに構成さ れる。Further, the battery main bodies 2 are arranged in a row in the left-right direction of the vehicle (vehicle width direction), that is, the side surfaces of the battery cases 3 facing only the above-mentioned end-side unit cells 4a are close to each other. At the same time, a heat exchange gap 12 is formed in the front-rear direction of the vehicle, that is, between the side surfaces of the battery cases 3 facing the end-side cells 4a and the inner cells 4b. . Therefore, as shown in FIGS. 2A and 2B, the areas of the cells 4a and 4b exposed to the heat exchange gap 12 are configured to be substantially the same.
【００１５】 尚、図２（ａ）に示す前記バッテリ集合体１１の配列は、前述の図８（ａ）， （ｂ）に示すタイプのバッテリ本体２を用いたもので、図２（ｂ）に示す上記バ ッテリ集合体１１の配列は、前述の図８（ｃ）に示すタイプの各バッテリ本体２ を用いたものである。The arrangement of the battery assembly 11 shown in FIG. 2A uses the battery main body 2 of the type shown in FIGS. 8A and 8B described above. The arrangement of the battery assembly 11 shown in FIG. 8 is the one using each battery main body 2 of the type shown in FIG. 8C.
【００１６】 次に、上記構成による本実施例の作用について説明する。 まず、バッテリ集合体１１を構成する複数個のバッテリ本体２が冷却される場 合、これら各バッテリ本体２を構成する端側単電池４ａと内側単電池４ｂとが面 した各バッテリケース３の側面間に形成された熱交換用間隙部１２から放熱され 、上記各バッテリ本体２が冷却される。Next, the operation of this embodiment having the above configuration will be described. First, when the plurality of battery main bodies 2 that form the battery assembly 11 are cooled, the side surface of each battery case 3 that faces the end-side single cells 4a and the inner single cells 4b that form each of these battery main bodies 2 Heat is dissipated from the heat exchanging gap 12 formed between them, and the battery bodies 2 are cooled.
【００１７】 また、上記端側単電池４ａのみ面した上記各バッテリケース３の側面同士は近 接して連設されているため、これら各バッテリケース３の側面から放熱されるこ とはなく上記端側単電池４ａと上記内側単電池４ｂとの熱交換条件が略同一とな る。Further, since the side surfaces of the battery cases 3 facing only the end-side unit cells 4a are arranged in close proximity to each other, heat is not radiated from the side surfaces of the battery cases 3 and the ends are not connected. The heat exchange conditions between the side unit cell 4a and the inside unit cell 4b are substantially the same.
【００１８】 一方、上記各バッテリ本体２が暖められる場合は、上述の冷却される場合とは 逆に、上記端側単電池４ａと上記内側単電池４ｂとが面した上記各バッテリケー ス３の側面間に形成された上記熱交換用間隙部１２から受熱して、上記各バッテ リ本体２が暖められる。On the other hand, when each of the battery main bodies 2 is warmed, contrary to the case of being cooled, the battery case 3 facing each of the end-side unit cells 4a and the inner-side unit cells 4b is opposite. The battery main body 2 is warmed by receiving heat from the heat exchange gap 12 formed between the side surfaces.
【００１９】 また、上記端側単電池４ａのみ面した上記各バッテリケース３の側面から受熱 されることはなく上記端側単電池４ａと上記内側単電池４ｂとの熱交換条件が略 同等となる。Further, heat is not received from the side surface of each battery case 3 facing only the end-side unit cell 4a, and the heat exchange conditions between the end-side unit cell 4a and the inner-side unit cell 4b are substantially equal. .
【００２０】 このため、従来のバッテリ集合体で生じていたバッテリ本体間の熱分布格差 （バッテリ集合体の内側に配設されているバッテリ本体より、バッテリ集合体の 外側に配設されているバッテリ本体の方が、熱交換が良いことに起因する熱分布 格差）が解消され、バッテリ集合体を構成する全てのバッテリ本体の熱交換が良 くなり、バッテリ本来の能力を十分に発揮させることができ、また、内側に配設 されているバッテリ本体のバッテリ寿命を本来の長さで使用することが可能とな る。Therefore, the heat distribution difference between the battery bodies that occurs in the conventional battery assembly (the battery arranged outside the battery assembly with respect to the battery body arranged inside the battery assembly) In the main body, the heat distribution difference caused by good heat exchange is eliminated, and the heat exchange of all the battery bodies that make up the battery assembly is improved, and the original capacity of the battery can be fully exerted. In addition, it is possible to use the battery life of the battery body disposed inside the battery with the original length.
【００２１】 また、バッテリ集合体における熱分布格差を解消することにより、バッテリ集 合体の寿命等を容易に推測・判断できるため、定期的な保守・点検のメンテナン スが可能となり、また、メンテナンスも、バッテリ集合体を構成する各バッテリ 本体全てについて行なうことなくサンプル抽出で行うことが可能となり、作業性 が向上する。Further, by eliminating the heat distribution difference in the battery assembly, it is possible to easily estimate and determine the life of the battery assembly and the like, which enables maintenance and inspection on a regular basis, and also maintenance. , It becomes possible to perform sample extraction without performing all of the individual battery bodies that make up the battery assembly, thus improving workability.
【００２２】 尚、端側単電池のみ面した各バッテリケースの側面同士を近接して連設する場 合に隙間が生じる際、例えば、バッテリケースの成形上、バッテリケースの上面 から下面にかけてできる抜きテーパ面等により隙間が生じる際には、この隙間に 発泡材等の断熱部材を充填するようにしても良い。When a gap is created when the side surfaces of the battery cases facing only the end-side cells are arranged in close proximity to each other, for example, when molding the battery case, a punching can be made from the upper surface to the lower surface of the battery case. When a gap is created by the tapered surface or the like, the gap may be filled with a heat insulating member such as a foam material.
【００２３】 次に、図３〜図６は本考案の第二実施例を示し、図３はバッテリ集合体を有す る電気自動車の透視平面図、図４はバッテリ集合体を有する電気自動車の透視正 面図、図５はバッテリ集合体搭載部の拡大説明図、図６はバッテリ本体の固定を 容易にした梁部の説明図である。 尚、本第二実施例は、端側単電池と内側単電池とが面した各バッテリケースの 側面間に形成された熱交換用間隙部に、さらに、梁部を形成したことが前記第一 実施例と異なる。3 to 6 show a second embodiment of the present invention, FIG. 3 is a perspective plan view of an electric vehicle having a battery assembly, and FIG. 4 is an electric vehicle having a battery assembly.

Different from the embodiment.
【００２４】 すなわち、これらの図において、符号２０は電気自動車を示し、この電気自動 車２０のバッテリ集合体搭載部２１の床面２２に、バッテリ集合体１１が配設さ れている。That is, in these drawings, reference numeral 20 indicates an electric vehicle, and the battery assembly 11 is disposed on the floor surface 22 of the battery assembly mounting portion 21 of the electric vehicle 20.
【００２５】 また、前記第一実施例と同様、上記バッテリ集合体１１を構成する各バッテリ 本体２は、車両の左右方向（車幅方向）の側面が近接して連設されるとともに、 車両の前後方向の側面間に熱交換用間隙部１２が形成されて配設されている。In addition, as in the first embodiment, the battery main bodies 2 forming the battery assembly 11 are arranged such that the side surfaces in the left-right direction (vehicle width direction) of the vehicle are closely adjacent to each other, and A heat exchange gap portion 12 is formed and arranged between the side faces in the front-rear direction.
【００２６】 さらに、上記熱交換用間隙部１２が形成された上記バッテリ集合体搭載部２１ の床面２２には、車両の左右に渡って梁部２３が形成されている このように、梁部２３を形成することにより、前記第一実施例の効果に加え、 車両の硬性を高めることができ、また、各バッテリ本体２の固定位置も容易に決 定できる。Further, a beam portion 23 is formed across the left and right of the vehicle on the floor surface 22 of the battery assembly mounting portion 21 in which the heat exchange gap portion 12 is formed. By forming 23, in addition to the effect of the first embodiment, the rigidity of the vehicle can be enhanced, and the fixing position of each battery body 2 can be easily determined.
【００２７】 さらに、図６に示すように、上記梁部２３に、取付け穴２５を設けることによ り、各バッテリ本体２の固定が、従来の固定のようにホルダ２６とロッド２７を 用いて簡単に行うことができる。Further, as shown in FIG. 6, by providing the beam portion 23 with the mounting hole 25, each battery main body 2 is fixed by using the holder 26 and the rod 27 as in the conventional fixing. Easy to do.
【００２８】 尚、他の構成、作用効果は前記第一実施例と同様であるので説明は省略する。 次に、図７は本考案の第三実施例によるバッテリ集合体の熱交換用間隙部の説 明図である。 尚、本第三実施例は、各バッテリケースの側面間の熱交換用間隙部に形成され た梁部に、通風口を形成するとともに、梁部内部を空調用ダクトとして構成した ことが前記第二実施例と異なる。The rest of the configuration, functions and effects are the same as in the first embodiment, so a description thereof will be omitted. Next, FIG. 7 is an explanatory view of a heat exchange gap portion of a battery assembly according to a third embodiment of the present invention. In the third embodiment, a ventilation port is formed in the beam formed in the heat exchange gap between the side surfaces of each battery case, and the inside of the beam is configured as an air conditioning duct. Different from the second embodiment.
【００２９】 すなわち、図７に示すように、前記バッテリ集合体１１の熱交換用間隙部１２ に形成されている梁部３１の両側面（バッテリ本体２に面した部位）に、通風口 ３２を形成するとともに、上記梁部３１内側を、図示しない空調用ユニットと接 続して、この梁部３１内側を空調用ダクト３３として構成する。尚、上記空調用 ユニットは、車室内空調用ユニットと共用としても独立としても良い。That is, as shown in FIG. 7, ventilation holes 32 are provided on both side surfaces (portions facing the battery main body 2) of the beam portion 31 formed in the heat exchange gap portion 12 of the battery assembly 11. While being formed, the inside of the beam portion 31 is connected to an air conditioning unit (not shown) to configure the inside of the beam portion 31 as an air conditioning duct 33. The air conditioning unit may be shared with or independent of the vehicle interior air conditioning unit.
【００３０】 このような構成とすることにより、上記バッテリ本体２が発熱して冷却が必要 な場合には、上記空調用ユニットから冷却風を上記空調用ダクト３３に送り、上 記通風口３２から冷却風を上記バッテリ本体２に吹き付けて冷却する。With such a configuration, when the battery main body 2 generates heat and needs to be cooled, the cooling air is sent from the air conditioning unit to the air conditioning duct 33, and the air is passed through the ventilation port 32. Cooling air is blown onto the battery body 2 to cool it.
【００３１】 また、寒冷地等での使用等により、上記バッテリ本体２を暖める場合には、上 記空調用ユニットから温風を上記空調用ダクト３３に送り、上記通風口３２から 温風を上記バッテリ本体２に吹き付けて暖める。When the battery main body 2 is warmed up due to use in a cold region or the like, warm air is sent from the air conditioning unit to the air conditioning duct 33 and warm air is blown from the ventilation port 32. The battery body 2 is sprayed and warmed.

【００３４】[0034]
以上、説明したように本考案によれば、バッテリ本体を複数個配設してバッテ リ集合体を形成した電気自動車のバッテリ装置において、端側単電池のみ面した 各バッテリケースの側面同士を近接して連設するとともに、端側単電池と内側単 電池とが面した上記各バッテリケースの側面間に熱交換用間隙部を形成したので 、上記バッテリ集合体を構成する複数個のバッテリ本体間の熱交換のばらつきを 、これら各バッテリ本体を構成する単電池レベルで良好に均衡させられ、上記各 バッテリ本体の有する性能を十分に発揮させるとともに、上記各バッテリ本体の 寿命を向上させることができ、また、メンテナンス性を向上させることが可能と なる。 As described above, according to the present invention, in a battery device of an electric vehicle in which a plurality of battery bodies are arranged to form a battery assembly, the side surfaces of the battery cases facing only the end-side cells are brought close to each other. Since the heat exchange gaps are formed between the side faces of the battery cases facing the end-side cells and the inner cells, the gap between the plurality of battery bodies forming the battery assembly is increased.
