Abstract

本发明提供一种电池组。该电池组(1)包括在车辆搭载状态下在上下方向上设有规定的间隙(G1、G2)地堆叠的多个电池组件(3、5、7)、及以面对上述规定的间隙(G1)的状态安装在该电池组件(3、5、7)的侧部的电池控制器(13)。

Description

电池组
技术领域
本发明涉及一种电池组。
背景技术
例如在专利文献1中公开有将多个电池排列起来做成电池组件，并将多个该电池组件组合起来构成电池组的技术。特别是在电力汽车中，将上述电池组搭载于电力汽车来作为电动机的驱动源。
专利文献1：日本特开2003-45384号公报
但是，在以往的电池组中，在对电池控制器等辅助器件类进行冷却的情况下，需要设置专用的冷却装置，因此成为导致重量增加和成本上升的主要原因。
发明内容
因此，本发明的目的在于提供一种不设置专用的冷却装置就能够高效地将电池控制器冷却的电池组。
本发明的电池组隔开规定间隙地堆叠多个电池组件，以使电池控制器面对上述规定间隙的状态将该电池控制器安装在该电池组件上。另外，本发明的电池组件不仅包含由多个电池构成的电池组件，也包含由单体电池构成的电池组件。
附图说明
图1是表示本发明的实施方式的电池组的立体图。
图2是表示自图1中的电池组拆下辅助器件类后的状态的立体图。
图3是图2的侧视图。
图4是表示自图3中的电池组拆下安装面板后的状态的侧视图。
具体实施方式
下面，将本发明的实施方式与附图一同详细说明。
图1是表示本发明的实施方式的电池组的立体图。另外，以下对将在厚度方向上排列有多个电池的电池组件上下堆叠而成的电池组进行说明，但本发明也能够应用于将单体电池上下堆叠而成的电池组。
本实施方式的电池组1由沿上下方向堆叠的3层电池组件3、5、7、及安装在这些电池组件3、5、7的侧部的辅助器件类构成。在车辆搭载状态下，前方侧、后方侧和车宽度方向的朝向如图1中箭头所示地配置。上述电池组件由配置在最上层的上侧电池组件3、配置在高度方向中央侧的中央侧电池组件5、及配置在最下层的下侧电池组件7构成为三层。这些电池组件3、5、7彼此借助沿上下方向延伸的纵长状的支承板11相连结。另外，电池组件3、5、7各自将多个板状的电池9在车宽度方向(电池9的厚度方向)上并联连结。并且，具体地讲，上述辅助器件类包含电池控制器(例如锂离子电池控制器)13、配线(未图示)。该电池控制器13用于对电池组1的充电放电进行控制和监视。由于因该控制等而产生热量，因此，为了将电池控制器13保持在规定温度以下，需要适当地冷却。
图2是表示自图1中的电池组拆下辅助器件类后的状态的立体图，图3是图2的侧视图。
在拆下了辅助器件类后的电池组1的侧部设有后述的加强构件37和自该加强构件37之上安装的安装板21。该安装板21的外周部分利用螺栓连结在电池组1的侧面。在安装板21的高度方向大致中央部，利用侧视呈大致X字形交叉的肋21a形成有4个大致三角形的开口部21b。以覆盖这些开口部21b的方式安装有以单点划线表示的电池控制器13。另外，设置在上侧电池组件3与中央侧电池组件5之间的第1间隙G1(参照图4)面对安装板21的开口部21b地配置。
图4是表示自图3拆下安装面板后的状态的侧视图。
如图4所示，在上侧电池组件3、中央侧电池组件5和下侧电池组件7的侧面设有矩形的端板31。在该端板31上接合有加强构件37。该加强构件37结合于沿上下方向延伸的纵长状的支承板11。
另外，在上侧电池组件3与中央侧电池组件5之间形成有第1间隙G1，在中央侧电池组件5与下侧电池组件7之间形成有第2间隙G2。即，上侧电池组件3与中央侧电池组件5的上下距离是D1，中央侧电池组件5与下侧电池组件7的上下距离是D2。这样，电池组件3、5、7在搭载于车辆的状态下，彼此在上下方向上隔开规定的间隙G1、G2地配置。第1间隙G1的上下尺寸D1形成为大于第2间隙G2的上下尺寸D2。
而且，如单点划线所示，电池控制器13面对第1间隙G1地配置。
下面，说明本发明的实施方式的作用效果。
本实施方式的电池组包括设有规定的间隙G1、G2地堆叠的多个电池组件3、5、7、及面对上述规定的间隙G1地安装在该电池组件3、5、7的侧部的电池控制器13。
如上所述，电池控制器13用于对电池组1的充电放电进行控制和监视，因该控制等而产生热量。因而，需要对电池控制器13进行冷却。在此，由于在电池组件3、5、7相互之间设有第1间隙G1和第2间隙G2，因此，利用空气的对流自第1间隙G1和第2间隙G2朝向外方放出空气。因而，通过将电池控制器13面对这些间隙G1、G2地配置，不使用特别的装置等就能够利用自然对流高效地将电池控制器13冷却。
另外，在本实施方式中，第1间隙G1的上下尺寸D1形成为大于第2间隙G2的上下尺寸D2，电池控制器13面对上侧的第1间隙G1地配置。这样，在设有多个间隙的情况下，通过面对最大的间隙D1能够高效地将电池控制器13冷却。
另外，以引用方式将日本特愿2009-106893号(申请日：2009年4月24日)的全部内容纳入本说明书。
以上，按照实施方式说明了本发明的内容，本发明并不限定于这些记载，对于本领域技术人员，能够进行各种变形及改良是显而易见的。
在上述实施方式中，电池控制器13面对由多个电池9构成的电池组件3、5、7的间隙G1、G2地配设。但是，也可以将单体电池隔开规定间隙地堆叠，将电池控制器以面对该间隙的状态安装于上述单体电池。
工业实用性
在本发明中，由于将电池控制器以面对形成在多个电池组件之间的规定间隙的状态安装于上述电池组件，因此，能利用从上述规定间隙流出的空气流将电池控制器冷却。因而，不设置专用的冷却装置就能够高效地将电池控制器冷却。
