Description

电池模块结构
技术领域
本发明涉及一种电池模块结构,更具体涉及一种具有通过电连接单元电池来实现的电池模块的结构。
背景技术
仅仅具有一个单元电池的电池模块不能获得足够的容量和电压,因此电池模块必须通过连接多个单元电池来实现,为了在电池模块中获得足够的容量和电压,需要一种可以电连接单元电池的结构。
如上所述,连接单元电池应该能够确保稳定的电连接,并可以容易地制造和组装单元电池,同时确保耐用性。
并且,根据电池模块的用途或位置,电池模块通常以各种形状和结构被实现。因此,提供一种连接单元电池以便能够容易地应用到具有各种结构的电池模块上并且在布置结构和可容纳单元电池的数量上比较灵活的结构是很有利的。
背景技术部分公开的上述信息仅用于帮助理解本发明的背景,因此可能包含并未构成本国本领域技术人员已知的现有技术的信息。
发明内容
本发明致力于提供一种电连接单元电池的电池模块结构,以便能够确保单元电池之间的稳定连接,以更有效的方式进行制造和组装,保证高耐用性,该结构能够容易地应用于各种形状和结构的电池模块,并且可以以各种方式来自由地确定单元电池的布置结构和数量。
本发明的一个典型实施方式公开一种电池模块结构,包括在边缘上具有正极、负极电池极耳的单元电池以引出电流;分别连结于单元电池的电池极耳的多个插座,以及电连接插座的多个汇流条。
有利地,在本发明所示的实施方式中,确保单元电池之间的稳定连接,制造和组装更简便,确保高耐用性,该结构可以在以各种方式自由确定单元电池的布置结构和数量的同时,电连接单元电池。
本发明的方法和设备还具有其他特征和优点,通过在此结合的附图和本发明下列具体描述中更详细地显而易见或列举,该附图和下列具体描述一起用于解释本发明的某些原理。
附图说明
图1示出根据本发明一个典型实施方式的电池模块结构的实施例的视图;
图2示出包含在根据本发明一个典型实施方式的电池模块中的单元电池结构的视图;
图3是示出图2所示的插座分开时的视图;
图4是示出当汇流条被连结且与单元框架分开以使图2所示的单元电池构成电池模块时的视图;
图5和6是示出当根据本发明一个典型实施方式的单元电池以各种方式被连结时的实施例的视图。
应当理解的是,附图不必按比例绘制,而是呈现出说明本发明基本原理的各种优选特征的简化表示。本文中所公开的本发明的特定设计特征,包括例如特定尺寸、方向、位置和形状,这些特征将部分地由预期的特定应用和使用环境来确定。
在附图中,在全部的几张图中,附图标记始终指代本发明的相同或等同部件。
具体实施方式
以下将参照附图具体描述本发明的示例性实施方式,这些实施方式的实施例将在附图中示出并在下面进行详细说明。尽管将结合具体实施方式来描述本发明,然而应该理解的是,本说明并不意图将限制到这些具体实施方式。相反地,本发明意图不仅覆盖具体实施方式,并且覆盖由所附权利要求书所限定的本发明的精神和保护范围内的各种变型、修改及其它实施方式。
参考图1-图4,根据本发明一个典型实施方式的电池模块结构,包括多个单元电池3,每个单元电池3的边缘上具有正、负极电池极耳1,用于引出电流;多个连结到每个单元电池3的电池极耳1的插座5;以及多个电连接到插座5的汇流条7。
单元电池3的电池极耳1形成为板状,从单元电池3的一侧突出,插座5具有连接面9,该连接面9与板状突出的电池极耳1相连且面接触。
也就是说,通过在确保电连接的同时,利用焊接或钎焊将插座5连结到每个单元电池3的电池极耳1上,并通过汇流条7连接单元电池3的插座5,来得到电池模块11。
图1所示的电池模块11是通过将单元电池3放入单元框架13中,如图4所示,然后将多个单元框架13重叠来获得的。
在典型实施方式中,插座5具有槽17,该槽垂直于由单元电池3形成的平面而开设,使得汇流条7的插入部15插入到槽17中并在与由单元电池3形成的平面平行的方向上电连接,其通过现有技术中各种类型的凹槽(socket)获得。因此,通过将汇流条7插入插座5中来实现电连接结构的可靠性已被充分验证。
此外,汇流条7具有连接插入部15的本体19。插入部15的两侧从本体19朝向插座5的槽17以直角弯曲。
因此,根据具有上述结构的电池模块11的结构,可以在不特别改变每个单元电池3的电池极耳1的形状的情况下确保稳定的电连接。因此,制造过程更高效,成本更低廉。此外,在单元电池3中发生因形状变化而产生破裂的可能性小。因此,可进一步改善耐用性。
此外,为了电连接,每个单元电池3的电池极耳1不直接通过焊接或螺栓或螺母等来连接。作为替代地,单元电池3可以通过附着/分离汇流条7而容易地连接和断开,使得单元电池3的数量和布置可以自由选择。单元电池可以自由布置,例如,如图5和6所示,单元电池沿相同方向和相反方向布置,或者两个单元电池也可以交替地布置。
更进一步地,本发明的电池模块11的结构比传统模块类型更薄,因而在实现具有弹性外罩的袋型电池模块上具有很大的优势。
此外,上述的插座5可以由非导电物质包裹,以使电池极耳1在工作环境中不暴露在外面,并避免短路,因此显著提高安全性。
上面已经出于说明和描述的目的描述了本发明的具体实施方式。这些实施方式不意图将本发明扩大或限制到所公开的精确形式,很显然,根据上述教导还可以做出许多修改和变型。为了说明本发明的某些原理及其实际应用而挑选并描述这些典型实施方式,以使本领域技术人员能够做出和利用本发明的各个典型实施方式及其各种修改和变型。本发明的保护范围意图由权利要求书及其等价形式限定。
