Description
发明背景
技术领域
本发明涉及一种蓄电装置,所述蓄电装置利用端板在多个电池上施加约束力。
背景技术
在某些情况下,当多个单电池用于形成电池组时,多个单电池沿着一方向排列。一对端板放置在单电池的沿着排列方向的两个端部处,并且端板用于在多个单电池上施加约束力(例如,参见日本专利申请公报No.2006-253149(JP-A-2006-253149))。
然而,在端板与单电池相接触的结构的情况下,担心的是,因为单电池的热量被传递到端板,所以与端板相接触的单电池的温度变得低于不与端板相接触的其它单电池的温度。在这种情况下,温度根据构成电池组的多个单电池发生变化。
发明内容
根据本发明的一方面的蓄电装置包括:多个电池,所述多个电池沿着预定方向排列;一对端板,所述一对端板将沿着所述预定方向的所述多个电池夹在中间;和沿着所述预定方向延伸的约束构件,所述约束构件固定到所述一对端板,并且经由端板将约束力施加在沿着所述预定方向的所述多个电池上。每个端板均包括第一板和第二板。所述第一板在面向相邻的电池的表面上具有多根肋,并且由绝缘材料形成。所述第二板在与面对毗邻的电池的所述表面相对的侧部上固定到第一板,并且由比用于第一板的绝缘材料更坚固的材料形成。
第一板可以由树脂形成,而第二板可以由金属形成。第一板可以具有在形成在所述第一板中的多根肋的一部分肋中形成的紧固部分,用于紧固约束构件。利用这种构造,在将约束构件紧固到紧固部分时施加的外力被肋接收,使得能够抑制第一板的变形。
例如,所述多根肋可以至少包括:第一肋,所述第一肋沿着第一方向在正交于所述预定方向的平面内延伸;和第二肋,所述第二肋沿着不同于第一方向的第二方向在所述平面中延伸。当使用沿着不同方向延伸的肋时,能够抑制第一板甚至在形成肋时的强度减小。
第一板的与第二板相接触的表面可以是基本平坦的。这使得容易将第二板附接到第一板。可以利用第一板的肋在电池的毗邻第一板的表面上形成封闭空间。当形成封闭空间时,防止空气在封闭空间和外部空间之间流动。通过将空气保持在封闭空间中,能够抑制电池的热量流动到第一板。
隔板可以放置在电池中的沿着预定方向相互毗邻的两个电池之间。隔板能够用于在所述两个电池的表面上形成供热交换介质流动通过的空间。利用这种构造,热交换介质与电池的表面相接触,使得能够调节电池的温度。
根据本发明,能够通过形成在第一板上的肋在电池的表面上形成空气层,使得能够阻止单电池的热量传递到第一板。具体而言,能够减小第一板和电池之间的接触表面的面积,以抑制通过接触表面进行的热传递。
另外,第二板附接到形成有肋的第一板,以确保端板具有较高的强度。当单独使用第一板作为端板时,端板的强度相对较低,因此,当使用由比用于第一板的材料更坚固的材料形成的第二板时,确保端板具有较高的强度。
附图说明
将在下文中参照附图描述本发明的示例性实施例的特征、优势以及技术和工业意义,在所述附图中,相同的附图标记表示相同的元件,并且其中:
图1是电池组的外部视图;
图2是隔板的主视图;
图3示出了从外侧观察到的端板;
图4示出了从内侧观察到的端板;
图5是沿着图3中的线V-V获得的横截面;和
图6是沿着图3中的线VI-VI获得的横截面。
具体实施方式
将在下文中描述本发明的实施例。
将参照图1描述作为本发明的实施例的用作蓄电装置的电池组。图1是电池组的外部视图,并且图1中示出的X、Y和Z轴线彼此正交。
这个实施例的电池组11能够安装在车辆上,并且车辆的示例包括混合动力车辆和纯电动车辆。混合动力车辆是除了配备有电池组11之外还配备有内燃机或燃料电池作为驱动车辆的动力源的车辆。纯电动车辆是仅配备有电池组11作为车辆的动力源的车辆。
电池组11可以连接到电动机/发电机(未示出),所述电动机/发电机接收来自电池组11的输出以产生驱动车辆的动能。由电动机/发电机输出的转矩经由动力传输机构传输到车轮。
可以将升压电路和换流器放置在电池组11和电动机/发电机之间。当放置升压电路时,能够升高或者增大电池组11的输出电压。当使用换流器时,能够将电池组11输出的直流(DC)电转换成交流(AC)电,以便能够将三相交流电动机用作电动机/发电机。电动机/发电机将车辆制动期间所产生的动能转换成电能,并且将电能输出到电池组11。电池组11储存由电动机/发电机供应的电能。
电池组11具有多个沿着X方向排列的单电池111,所述多个单电池中的每一个均用作电池。矩形单电池用作单电池111。可以适当地设置构成电池组11的单电池111的数量。例如,可以根据所需要的电池组11的电力以及每个单电池111的电力设定单电池111的数量。
诸如镍氢电池或锂离子电池的次级电池可以用作单电池111。作为次级电池的替代方案,可以使用双电层电容器(电容器)。尽管在本实施例的电池组11中,多个单电池111沿着X方向排列,但是本发明并不局限于此。具体地,可以应用这样的构造,在所述构造中,使用多个单电池111形成电池模块,并且多个电池模块沿着X方向排列。
发电元件容纳在单电池111中。发电元件是能够充放电的元件。例如,发电元件可以包括阴极元件、阳极元件和隔离装置,所述隔离装置包括放置在阴极元件和阳极元件之间的电解液。通过在集电器的表面上形成阴极活性材料层来获得阴极元件。通过在集电器的表面上形成阳极活性材料层来获得阳极元件。
阴极端子111a和阳极端子111b设置在单电池111的上侧部上。阴极端子111a电连接到发电元件的阴极元件。阳极端子111b电连接到发电元件的阳极元件。两个毗邻的单电池11经由汇流条彼此电连接。在这个实施例中,所有单电池111串联电连接。电池组11可以包括并联电连接的单电池111。
在这个实施例中,使用汇流条模块110,所述汇流条模块110中结合有多条汇流条。汇流条模块110放置在电池组11的上侧部上。汇流条模块110具有多条汇流条和保持汇流条的保持件。保持件由诸如树脂的绝缘材料形成。
图2中示出的隔板114放置在沿着X方向相互毗邻的两个单电池111之间。隔板114由诸如树脂的绝缘材料形成,并且用于在单电池111的每个表面上形成空间。这个空间用作供调节单电池111温度的热交换介质流动通过的空间。隔板114具有多个突出部114a,所述突出部114a的末端接触单电池111,使得热交换介质流动通过的空间形成在单电池111的每个表面上。
在这个实施例中,突出部114a沿着Y方向延伸,并且多个突出部114a沿着Z方向并排布置。因此,热交换介质在Y方向上沿着突出部114a流动。突出部114a的形状并不局限于图2中示出的形状。具体而言,只要在单电池111的每个表面上形成供热交换介质流动通过的空间即可。
通过使热交换介质流动通过由突出部114a形成的空间,热交换介质与单电池111相接触,使得能够调节单电池111的温度。当单电池111正在产生热量时,例如,通过使冷却热交换介质与单电池111相接触,抑制了单电池111的温度升高。另一方面,当单电池111被过冷却时,通过使加热热交换介质与单电池111相接触,能够使单电池111升温。
一对端板112放置在电池组11的两个端部处。用作约束构件的约束带113沿着多个单电池111的排列方向延伸,并且约束带113的两个端部部分固定到所述一对端板112。约束带113中的两个放置在电池组11的上侧部上,并且约束带113中的两个放置在电池组11的下侧部上。
当约束带113固定到端板112时,所述一对端板112沿着使得所述一对端板112彼此靠近的方向移动。以这种方式,约束力被施加在被夹在所述一对端板112之间的多个单电池111上。约束力指的是沿着X方向夹紧单电池111的力。
尽管这个实施例的约束带113形成为板状形状,但是本发明并不局限于此。具体而言,只要约束带113固定到一对端板112并且能够将约束力施加到单电池111上即可。例如,作为约束带113的替代方案,能够使用形成为圆柱状的约束构件。
将参照图3至图6具体描述端板112的结构。图3示出了从外侧观察到的端板112。图4示出了从内侧(单电池111侧)观察到的端板112。图5是沿着图3中的线V-V获得的横截面,并且图6是沿着图3中的线VI-VI获得的横截面。
端板112具有用作第一板的树脂板1121和用作第二板的金属板1122。引导部分1121a设置在树脂板1121的上侧部上,约束带113被固定在每个所述引导部分1121a处。引导部分1121b设置在树脂板1121的下侧部上,约束带113被固定在每个所述引导部分1121b处。
如图4所示,树脂板1121在树脂板1121接触单电池111的侧部上的表面(Y-Z平面)上具有第一肋1121c、第二肋1121d和第三肋1121e。第一肋1121c沿着Y方向延伸,并且多根第一肋1121c沿着Z方向并排布置。
第一肋1121c的末端与单电池111相接触。因此,如图5和图6所示,多个空气层M形成在单电池111的表面上。空气层M是这样的空间,所述空间中的每一个都被树脂板1121和单电池111包围。通过在单电池111的表面上形成空气层M,能够阻止单电池111的热量传递到端板112(树脂板1121)。
空气的热导率低于树脂板1121的热导率,因此,单电池111的热量难以传递到树脂板1121。通过使单电池111的热量更不容易传递到端板112,能够抑制单电池111的温度下降。
空气层M可以是封闭的空间。利用这种构造,抑制空气在空气层M和端板112的外侧之间流动。如果空气被保持在空气层M中,即使当单电池111的热量到达空气层M时,也能够抑制热量从空气层M逸出。这里,封闭的空间不一定指完全封闭的空间,只要抑制空气在空气层M和端板112的外侧之间流动即可。
第二肋1121d沿着Z方向延伸,并且与第一肋1121c交叉。多根第二肋1121d沿着Y方向并排布置。第三肋1121e沿着使得第三肋1121e与第一肋1121c和第二肋1121d交叉的方向(倾斜方向)延伸。用于紧固约束带113的紧固部分F定位在第三肋1121e的第四端部部分中的每一个处。
设置有沿着不同方向延伸的第二肋1121d和第三肋1121e,使得能够增加树脂板1121的强度。另外,因为设置有第三肋1121e,所以能够在将约束带113紧固到树脂板1121时抑制树脂板1121的变形。
与此同时,如图5所示,树脂板1121具有突出部1121f,所述突出部1121f与单电池111的底部相接触。与肋1121c相比,突出部1121f沿着X方向突出得更多。如图6所示,树脂板1121具有突出部1121g,所述突出部1121g与单电池111的侧部相接触。与肋1121c相比,突出部1121g沿着X方向突出得更多。突出部1121f和1121g彼此连续,并且形成为在沿着X方向观察时沿着单电池111的外周延伸。
金属板1122固定到树脂板1121。树脂板1121的一个侧部与单电池111相接触,并且树脂板1121的另一个侧部与金属板1122相接触。树脂板1121的与金属板1122相接触的侧部基本是平坦的。因此,能够容易地将金属板1122附接到树脂板1121。
金属板1122具有孔1122a和1122b。孔1122a用于供螺栓***通过,并且该螺栓用于将约束带113固定到端板112,所述约束带113被固定在引导部分1121a处。孔1122b用于供螺栓***通过,该螺栓用于将约束带113固定到端板112,所述约束带113被固定在引导部分1121b处。
在树脂板1121中形成多根肋1121c会降低树脂板1121的强度。因此,在这个实施例中,通过将金属板1122固定到树脂板1121来确保端板112的强度。另外,金属板1122具有平坦表面,使得约束带113能够容易地附接到金属板1122。
尽管在这个实施例中端板112包括树脂板1121和金属板1122,但是本发明并不局限于此。端板112可以包括对应于树脂板1121并且由绝缘材料形成的板和对应于金属板1122并且由比前述板的材料更为坚固的材料形成的板。
已经仅为说明性目的而参照示例性实施例描述了本发明。应当理解的是,上述描述并不是详尽的,也不用于限制本发明的形式,并且,本发明可以适于用在其它***或应用中。本发明的范围涵盖本领域技术人员能够想到的多种修改方案和等效布置方案。
