Description

电池模块及用于制造其的方法
技术领域
本发明涉及根据独立权利要求前序部分所述的一种电池模块、一种用于制造其的方法以及其应用。
背景技术
从现有技术中已知，电池、例如锂离子电池，至少由一电池模块或有利地也由多个电池模块组成。这种电池模块优选具有大量单个的电池单元，这些电池单元彼此电连接，其中，这些单个的电池单元串联或并联地借助于单元连接器彼此连接。
在此已知，单元连接器具有柔性区域，用以平衡单个的电池单元相对彼此的运动或者也可以补偿在制造和装配电池单元时的公差。
此外，从US2004/0029311中已知一种用于制造所谓的固态电池的方法，其中，电池单元以温和的方式进行电接触。此外，从EP 2226747已知一种用于在基板上产生电路图案的方法和装置，其中，导体条与基板的表面侧导电连接。
发明内容
本发明提供一种具有独立权利要求的特征部分特征的电池模块、用于其制造的方法以及其应用。
在此提供一电池模块，其例如具有多个电池单元，例如可再充电的锂离子电池单元。多个电池单元例如理解为至少两个电池单元直至多于100个电池单元。多个电池单元例如彼此串联或并联连接以传导电流。在此也可行的是，多个电池单元组彼此串联地导电连接并且电池单元组本身彼此并联地导电连接。多个电池单元彼此的连接根据本发明借助于集成到柔性电路板中的柔性导体轨道进行。
被埋入柔性电路板中的柔性导体轨道用于使电池单元彼此导电连接的应用的特别优点在于，柔性导体轨道在柔性电路板内部关于其相对彼此的定位可以被预先定位且因此柔性导体轨道与在电池模块中设置的电池单元的电端子的相应电接触可以以高的局部精度以及时间相同地并因此非常快速地发生。以这种方式可以确保安装在相关电池模块中的电池单元的大数量的电接触。
本发明的其他有利实施方式是从属权利要求的主题。
有利的是，集成到柔性电路板中的柔性导体轨道以扁平导体带的形式实施。其有利地具有20至100μm、优选25至40μm的带厚，进一步优选30μm的带厚，以及1.5至5.0mm、优选2.0至3.2mm的宽度且进一步优选2.5mm的宽度。
在传统电池模块中，电池单元的电连接常常以铝线来进行。在此，可能会出现关于这种铝线与电池单元的电端子的可靠的材料锁合连接方面的问题，该连接还要承受电池模块运行期间的振动，而不会导致铝线脱落。在这方面，通过使用扁平导体带可以实现扁平导体带和电池单元的电端子之间的相应连接点的更高可靠性。
除了电池单元的相应电端子的可靠电接触之外，扁平导体条的使用还因其设计而提供用作保险丝的可能性。这是针对以下情况设置的，即存在过大的电流流过相关电池单元，这可能导致相应电池单元的危险状态。如果扁平导体条在其功能方面用作保险丝，则扁平导体条除了电池单元的端子的电接触之外还用作被动保险元件。在使用相应的扁平导体条时，在此情况下与传统的引线键合相比，可以使用扁平导体条的更短的保险导线长度，且因此导致在电池端子彼此之间的电连接区域中的很小的电损耗。
此外有利的是，电池模块具有两个柔性电路板，其中，第一柔性电路板与电池模块中包含的电池单元的第一电池端子处于导电接触中并且第二柔性电路板与电池模块中包含的电池单元的第二电池端子处于导电接触中。这能够实现例如多个电池单元的电接触，这些电池单元的电池电端子分别定位在电池单元壳体的末端表面上。例如，规格为18650或21700的经典圆形单元就是这种情况。
然而，如果例如使用具有棱柱形壳体的电池单元，其中分别分配给阳极或阴极的电端子位于相同的壳体表面上，则使用唯一一个柔性电路板就足够了，其中，埋入其中的柔性导体轨道将不同电池单元的端子彼此连接起来。
根据另一种有利的实施方式设置成，电池模块包括监控单元，其例如被实施成印刷电路板（PCB）形式的另外的电路板。监控单元以有利的方式例如用于监控电池模块的电性参数，如模块电压或电池单元电压或电池模块的运行温度。电接触在此情况下可以例如经由单独的电接触器件例如通过引线键合来进行。在该情况下单个或所有电池单元的电端子借助于导电的引线连接与监控单元的连接点连接。
此外有利的是，柔性印刷电路（FPC）形式的柔性电路板在电池单元的电端子的区域中具有穿通部（Durchbrechungen）。以这种方式可以补偿电池模块的放电器和电池单元的电端子之间的分级（Abstufungen）。
此外，本发明涉及一种用于制造前述的电池模块的方法。在该方法中，以有利的方式首先提供多个电池单元，并且在第二步骤中将这些电池单元的电端子与柔性电路板的柔性导体轨道材料锁合地连接起来。这可以以特别有利的方式通过激光焊接工艺进行，因为这可以在方法技术上特别快速地执行。特别合适的是在此使用波长为500至600nm的绿色激光，因为在这种情况下仅出现相关电池单元极小的热学加热。
此外有利的是，在集成到柔性电路板中的柔性导体轨道与电池单元的电端子材料锁合连接期间，柔性电路板被压到电池单元的表面上，在该表面上定位了其电端子。这有利地通过使用流体例如压缩空气、氮气或保护气体的体积流来进行，其中，该流体例如通过喷嘴或喷嘴梳产生并被对准到柔性电路板上。
根据本发明的电池模块可以以有利的方式在电运行或部分电运行的车辆例如电池电动车辆、混合动力车辆或插电式混合动力车辆中使用，或者在用于存储特别是再生产生的电能的固定能量存储器中使用，以及作为缓冲能量例如在燃料电池系统中使用。
附图说明
本发明的实施方式在附图中示出并在后面的附图描述中被详细阐释。其中：
图1a至1d 示出了根据本发明的一实施方式的电池模块的示意性截段图；
图2 示出了用于制造根据图1a至1d的电池模块的方法的流程图。
具体实施方式
图1a中在俯视图中示意性示出了根据本发明的电池模块10。该电池模块10包括多个电池单元12a-12d，它们例如被实施成具有柱形壳体的所谓的圆形单元。在此例如是锂离子电池单元。电池单元12a-12d相对彼此平行取向并且在模块块件14中位置固定地被固定。
为了接触电池单元12a-12d，例如采用柔性印刷电路（FPC）形式的柔性电路板20。柔性电路板20例如包括多个凹部22a-22d。与此相对应地设置柔性导体轨道24a-24d，它们横穿相应的凹缺22a-22d并且在其内部不埋入柔性电路板20的载体材料中。这允许了相应的导体轨道24a-24d在凹缺22a-22d内与关于柔性电路板20而言外部的电连接点的稍后的材料锁合连接。图1b中所示的柔性导体轨道24a-24d例如设有另外的连接点26，这些连接点允许了柔性电路板20例如到电池模块10的汇流排上的稍后的连接。
图1c中放大示出了图1a的图像截段。在此可看到电池单元12a-12c。如果根据图1b的柔性电路板20现在透视地定位在电池单元12a至12c上方，则凹缺22a、22b、22c位于电池单元12a-12c的表面上方的位置28a、28b、28c处。此外，将柔性导体轨道24a、24b、24c与电池单元12a-12c的图1中不可见的电端子材料锁合连接。在此产生了相应的连接点29a、29b、29c。
此外，电池模块10包括监控单元30，其例如用于监控电池单元12a-12c。为此，在连接点29a-29c和监控装置30之间设置电监控导线32a、32b、32c。它们本身安置在监控装置30的电接触点34a、34b、34c上，其中，监控装置30优选同样被实施成电路板，在该情况下以刚性线路板的形式被实施成印刷电路板（PCB）。连接点34a-34c也可以被称为所谓的平台（Landings）。借助于监控装置30可以例如在其电池单元电压、其温度或另外的电学或热学特征参量方面监控电池单元12a-12c。
本发明参照示例性电池单元12a-12c来阐述。不言而喻，更多个所述类型的电池单元或电池模块的所有电池单元可以以等效方式通过集成到柔性电路板中的柔性导体轨道接触且通过监控单元30监控。视应用目的而定，这里也可以监控单个的示例性电池单元或电池单元的整体。
图2中示意性示出了用于制造根据图1的电池模块的方法。
在此，首先在第一步骤50中提供一电池模块的多个电池单元。此外，同样提供包括柔性导体轨道的柔性电路板。在第二步骤52中将包括柔性导体轨道的柔性电路板定位在由电池模块的电池单元的表面所形成的大表面上，使得柔性电路板的凹缺完全重叠地定位在电池模块的电池单元的电池电端子上。
然后在第三步骤54中优选借助于激光焊接装置进行柔性电路板的柔性导体轨道与电池模块的电池单元的电池电端子的材料锁合连接。作为柔性电路板尤其是使用扁平导体带，其特征在于在20至100μm、特别是20至50μm的范围内的、并且特别是30μm的较小结构高度以及例如1.5至5mm、优选2至4mm的宽度且尤其是2.5mm的宽度。
由于这种尺寸设计，被实施成扁平导体带的柔性导体轨道同时还具有保险丝的特性，因为当电流超过最高值时它会熔化，从而阻止电流流过相关的电池单元。
在第四步骤56中，电池模块的监控单元分别利用导电连接与选定数量的电池单元或所有电池单元导电连接，优选在它们各自的电池端子区域中。这能够实现电池模块的电池单元的控制。
根据本发明的电池模块可以以有利的方式在电驱动或部分电驱动的车辆中，例如电池电动车辆、混合动力车辆或插电式混合动力车辆中使用，作为燃料电池系统中的缓冲电池使用或在用于存储例如再生产生的电能的固定存储器中使用。
