Description
技术领域
本发明涉及一种具有改进安全性的电池模块,并且特别涉及一种具有被彼此电连接的多个电池胞的电池模块,该电池模块包括:电压感测单元,该电压感测单元包括电压感测端子和传导部,该电压感测端子被电连接到电池胞的电极端子连接部,该传导部被连接到电压感测端子以把电压感测端子所检测到的电压传输到模块控制单元;和信号切断单元,该信号切断单元位于电压感测端子和连接部之间,用于当传导部中发生短路时中断检测到的电压的传输。
背景技术
近来,能够充电和放电的二次电池已广泛用作无线移动设备的能量源。另外,将二次电池作为诸如电动车辆(EV)、混合动力电动车辆(HEV)、以及插入式混合电动车辆(插入式HEV)的要求高输出和大容量的设备的动力源已引起了相当大的关注,已经开发了上述二次电池来解决由现有的使用化石燃料的汽油车和柴油车所引起的问题,诸如空气污染。
小型移动设备为每个设备使用一个或几个电池胞。另一方面,因为中大型设备需要高输出和大容量,所以中大型设备诸如车辆使用具有被相互电连接的多个电池胞的电池模块。
优选地,电池模块被制造成具有尽可能小的尺寸和重量。因此,通常使用能够以高的集成度进行堆叠并具有小的重量容量比的棱形电池或袋状电池作为中大型电池模块的电池胞。具体地,目前很多兴趣都集中在使用铝层压片作为护鞘构件(sheathing member)的袋状电池,因为该袋状电池的重量轻,并且袋状电池的制造成本低。
另外,电池模块被构造成具有其中多个电池胞被组合的结构。在其中过电压被施加到一些电池胞的情况下,过电流在一些电池胞中流动,或者一些电池胞过热,因此,电池模块的安全性和操作效率备受关注。为此,有必要提供检测控制这样的过电压、过电流或者过热的装置。
因此,电压传感器被连接到各自的电池胞以实时或者以预定的时间间隔检查和控制电池胞的操作状态。然而,这样的检测装置的安装或者连接非常简化用于组装电池模块的过程。另外,存在由于用于检测装置的多个电线可能出现短路的可能性。
另外,当由于二次电池的应用范围的扩展二次电池被用作用于车辆的电源时,有必要提供一种紧固构件,即使当一连串冲击或者振动被施加到二次电池时该紧固构件保持检测装置的稳定接触状态。
另一方面,在锂离子二次电池的情况下,有必要使用电压感测单元测量各自的电池的电压以便于检查各自的电池的状态。为此,在其中在电压感测单元中出现短路的情况下电池的安全性备受关注。
另外,当电池的安全性备受关注时的电压感测单元的保护对于电池系统来说是非常重要的。
因此,存在对于紧凑并且呈现被改善的安全性同时根本地解决上述问题的电池模块的高度需求。
发明内容
技术问题
因此,为解决以上问题和尚待解决的其它技术问题已经完成本发明。
本发明的目的是为了提供一种电池模块,该电池模块被构造成具有一种结构,在该结构中信号切断单元位于电压感测端子和传导部之间,使得当传导部中发生短路时中断检测到的电压的传输,从而改善电池模块的安全性。
本发明的另一目的是为了防止传导部着火并且通过信号切断单元的使用停止电池模块的电压感测操作。
技术解决方案
根据本发明的一个方面,通过提供一种电池模块能够完成以上和其它的目的,该电池模块具有被彼此电连接的多个电池胞,该电池模块包括:电压感测单元,该电压感测单元包括电压感测端子和传导部,该电压感测端子被电连接到电池胞的电极端子连接部,该传导部被连接到电压感测端子以把电压感测端子所检测的电压传输到模块控制单元;和信号切断单元,该信号切断单元位于电压感测端子和连接部之间,用于当传导部中发生短路时中断检测到的电压的传输。
因此,在根据本发明的电池模块中,信号切断单元位于电压感测端子和传导部之间,使得当传导部发生短路时中断检测到的电压的传输,从而大大地改善电池模块的安全性。
在优选示例中,电压感测端子中的每一个可以被构造成具有插座结构使得电压感测端子能够被容易地紧固到传导部。
传导部可以被构造成具有线束结构使得电压感测端子所检测到的电压能够被容易地传送到模块控制单元。
优选地,线束被构造成一个绝缘构件包围九根电线的结构。
具体地,在由于外力连接在电压感测端子和模块控制单元之间的电线发生短路的情况下,通过同时产生的高电流断开信号切断单元,因此通过电压感测端子检测到的电压信号不能够被传送到模块控制单元。
另外,根据本发明的电池模块可以防止电压感测端子着火并且通过信号切断单元的使用停止电池模块的电压感测操作。
模块控制单元可以基于电压感测端子所检测的电压信号控制电池模块的操作。例如,模块控制单元可以是电池管理系统(BMS)。但本发明不限于此。
在具体示例中,电池模块可以被构造成具有电池胞单元堆的结构,该电池胞单元堆:包括堆叠状态下彼此电连接的两个或者更多个六面体电池胞单元;模块壳体,电池胞单元堆被安装在该模块壳体中,使得电池胞单元堆直立在其侧面;以及电压感测端子,该电压感测端子被电连接到电池胞的电极端子连接部。
在上面的结构中,信号切断单元可以被安装在模块壳体的前面或者后面处。
在优选示例中,信号切断单元可以包括保险丝盒,该保险丝盒具有被安装在其中的保险丝。因此,在其中信号切断单元故障的情况下,足以仅更换保险丝盒,从而改善信号切断单元的维护。
保险丝盒可以具有各种结构,其示例如下。
在示例中,保险丝盒可以包括:电路板,保险丝被安装在该电路板处;和盖,该盖覆盖电路板以保护电路板。因此,当保险丝被断掉时,仅更换电路板就足矣,从而改善保险丝盒的维护。
在上面的结构中,例如,通过焊接保险丝可以被安装在电路板上,以增加在保险丝和电路板之间的耦接力。
根据情形,以插座端子的形状保险丝可以被安装在电路板上,从而改善保险丝盒的组装性。
可以基于电池模块的构造改变保险丝中的每一个的规格。例如,保险丝中的每一个可以具有3V至500V的直流电压和1A至5A的电流。然而,本发明不限于此。
电池胞每一个不被特别地限制,只要各个电池胞是能够充电和放电的二次电池。例如,电池胞中的每一个可以是锂二次电池、镍金属氢化物(Ni-MH)二次电池、或者镍镉(Ni-Cd)二次电池。在这样的二次电池当中,锂二次电池被优选地使用,因为锂二次电池呈现高输出重量比。
各个电池胞可以是板状二次电池,具有小厚度和相对大的宽度和长度,以使得当电池胞被堆叠以组成电池模块时最小化电池模块的整体大小。二次电池的优选示例可以是二次电池,该二次电池被构造成具有下述结构,在该结构中电极组件被安装在由包括树脂层和金属层的层压片形成的电池壳体中并且电极端子从电池壳体的上端和下端突出。具体地,电极组件可以被安装在由铝层压片形成的袋状电池壳体中。具有上述结构的二次电池可以被称为袋状电池胞。
电池胞中的每一个可以具有被形成在其上端和下端处的电极端子。
同时,模块壳体可以包括上壳体和下壳体,上壳体和下壳体通过垂直组装彼此耦接。因此,在其中电池胞堆被安装在下壳体中的状态下可以容易地实现在上壳体和下壳体之间的组装和拆卸。
在上面的结构中,电压感测单元可以包括:感测单元框架,该感测单元框架被安装在下壳体的前面和后面处;电压感测端子,该电压感测端子被插入到感测单元框架中;以及传导部,该传导部被连接在电压感测端子之间。
在另一示例中,下壳体可以在其前面和后面朝内设置有固定凹槽,电池胞的电连接部被插入和安装在该固定凹槽中。
下壳体可以在其前面处被设置有一对狭缝,通过所述一对狭缝能够插入单元电池胞堆的最外面的电极端子。
在通过狭缝插入最外面的电极端子之后,最外面的电极端子可以被弯曲以接触被布置在下壳体的后面处的汇流条。优选地,汇流条的上端可以被形成为期望的孔的形状,当上壳体和下壳体被彼此耦接时,被设置在上壳体的后面处的外部输入和输出端子通过该孔被引入。
下壳体可以在其前面和/或后面的下端处设置有紧固部,该紧固部从下壳体突出以将下壳体固定到外部设备,通孔被形成在紧固部的中间部分。
同时,电池胞单元中的每一个可以被构造成具有下述结构,该结构包括两个或者更多个电池胞和一对板状护鞘构件,该板状护鞘构件被耦接以覆盖除了电极端子的电池胞堆的外部。
因此,护鞘构件可以保护呈现低机械强度的电池胞并且抑制在电池胞的充电和放电期间的重复性膨胀和收缩波动以防止电池胞的密封部之间的分离。
在上面的结构中,电池胞单元中的每一个可以进一步包括减震构件,该减震构件被布置在电池胞之间的交界处以在电池胞的充电和放电期间抑制因电池胞的体积变化而导致的电池胞移动并且减震。
因此,减震构件由于在电池胞的充电和放电期间通过重复性膨胀和收缩波动引起的电池胞的体积的变化减震并且增加在电池胞之间的摩擦力以抑制电池胞的移动。
用于被插入在电池胞之间的交界处的减震构件的材料没有被特别地限制,只要减震构件由于电池胞的体积的变化减震并且增加电池胞之间的摩擦力以抑制电池胞的移动。优选地,减震构件是由具有多孔结构的聚合体树脂形成。多孔结构可以包括开放的气孔或者封闭的气孔。
聚合体树脂的种类没有被特别地限制。例如,聚乙烯、聚丙烯、聚丁烯、聚苯乙烯、天然橡胶、人工橡胶、NBR树脂、ABS树脂等等可以被使用。
优选地,护鞘构件中的每一个具有与电池胞堆的外部形状相对应的内部结构。特别地,在没有附加的紧固构件的情况下通过组装和紧固护鞘构件被彼此耦接。
作为护鞘构件的组合的耦接部的代表性示例,护鞘构件的组合的耦合部可以被构造为具有公母紧固结构使得当在其中护鞘构件被彼此接触使得护鞘构件彼此面向的状态下推压护鞘构件时通过弹性耦接彼此配合护鞘构件。
同时,在二次电池的充电和放电期间从二次电池产生热。被产生的热的有效散发对于增加电池的寿命来说是重要的。因此,护鞘构件中的每一个可以是由呈现高的传导性以在护鞘构件中更加容易地散发从电池胞产生的热的金属片形成。
在优选示例中,护鞘构件中的每一个可以在与其上端和下端相邻的侧面处被设置有台阶部件,该台阶部件具有预定的大小以容易地固定电池胞。根据情形,台阶部件可以被形成在与护鞘构件中的每一个的左端和右端相邻的侧面处。更加优选地,台阶部件被形成在与护鞘构件中的每一个的上端和下端和左端和右端相邻的侧面处以更加稳固地固定电池胞。
电池胞可以以各种形式被固定在护鞘构件中的每一个的上端和下端处。为了更加有效地固定,凹陷的台阶部件被优选地设置同时具有与电池胞的密封部相对应的形状和大小。
通过被形成在护鞘构件处的台阶部件和减震构件的组合最大程度地抑制电池胞的移动。
在优选示例中,根据本发明的护鞘构件中的每一个可以在其外部处被设置有多个线状凸缘,这些线状凸缘在横向方向(水平方向)中被彼此隔开,以提供冷却剂流动空间。在上面的结构中,线状凸缘中的每一个可以被构造成使得该线状凸缘的相对两端到达护鞘构件的相对两端。因此,在其中电池模块被堆叠的状态下,冷却剂(例如,空气)可以在护鞘构件的横向方向中流动,从而进一步改善冷却效率。
另外,护鞘构件中的每一个可以在其外部的上端和下端处被设置有条,该条在横向方向(水平方向)中被形成为彼此相对的形状。因此,当电池模块被堆叠时,护鞘构件200具有与电池模块的相邻的一个相对应的形状。因此,能够防止在电池模块之间的被堆叠的位置被彼此颠倒或者偏离。
根据本发明的另一方面,提供一种电池组,该电池组被构造成具有包括基于输出和容量的两个或者更多个电池模块的结构。
通过电气和机械地互连多个二次电池制造电池组使得电池组能够提供高输出和大容量。例如,通过在其中电池模块对被直立在横向方向中的状态下将两个或者更多个电池模块安装在电池框架中可以制造电池组。
根据本发明的又一方面,提供一种使用电池组作为电源的车辆。
特别地,考虑到基于所期待的输出和容量的安装效率和结构稳定性,具有上述结构的车辆可以被用作电动车辆、混合电动车辆、或者插入式电动车辆。

电压感测端子654中的每一个被构造成具有插座结构并且传导部652被构造成具有线束结构。
特别,线束被构造成具有一个绝缘构件包围九根电线的结构。
电压感测单元650包括:感测单元框架656,该感测单元框架656被安装在下壳体640的前面和后面处;电压感测端子654,该电压感测端子654被插入到感测单元框架656内;以及传导部652,该传导部652被连接在电压感测端子654之间。

在通过狭缝644插入最外面的电极端子之后,最外面的电极端子被弯曲以接触被布置在下壳体640的后面处的汇流条624。汇流条624的上端被形成为期望的孔628的形状,当上壳体630和下壳体640被彼此耦接时,设置在上壳体630的后面处的外部输入和输出端子626通过该孔被引入。
另外,下壳体640在其前面和后面的下端处被设置有紧固部648,该紧固部648从下壳体640突出以将下壳体固定到外部设备。通孔646被形成在紧固部648中的每一个的中间处。
图6是典型地示出袋状二次电池的结构的分解的透视图。
参考图6,袋状电池100被构造成具有一种结构,使得在电极引线110和120彼此相对的状态下,在该结构中两个电极引线110和120分别从电池本体130的上端和下端突出。
护鞘构件140是两单元构件。在电极组件(未示出)安装在被形成在护鞘构件140的容纳部中的状态下,护鞘构件140的接触区域的横向侧140b、上端140a以及下端140c被彼此结合,从而电池胞100被制造。护鞘构件140被构造成具有树脂层/金属箔层/树脂层的层压结构。因此,能够通过将热和压力施加到护鞘构件140的横向侧140b和上和下端140a和140c使得彼此焊接其树脂层彼此结合是彼此接触的护鞘构件140的横向侧140b与上和下端140a和140c。根据情形,使用结合剂护鞘构件140的横向侧140b与上端和下端140a和140c可以被彼此结合。

护鞘构件200被彼此耦接以覆盖除了所形成的电极端子110的电池胞100的堆的外部。护鞘构件200保护呈现机械强度低的电池胞并且抑制在电池胞的充电和放电期间的重复性的膨胀和收缩波动以防止电池胞的密封部之间的分离。

另外,护鞘构件200在其外部的上端和下端处被设置有条235,该条235在横向方向(水平方向)中被形成为彼此相对的形状。因此,当电池模块被堆叠时,护鞘构件200具有与电池模块的相邻的一个相对应的形状。因此,能够防止电池模块之间的被堆叠的位置被彼此颠倒或者偏离。
另外,护鞘构件200包括一对左电池胞盖211和右电池胞盖212,在没有使用附加的紧固构件的情况下一对左电池胞盖211和右电池胞盖212可以被彼此耦接。
