Abstract

根据本发明的示例性方面的一种蓄电池阵列除其他方面以外包括电路连接器总成和部分覆盖电路连接器总成的盖。盖包括槽。感测线路布线接收在槽内。

Description

用于蓄电池阵列的槽盖
技术领域
本发明涉及一种包括尺寸适于接收感测线路布线(sense-line wiring)的槽的电路连接器总成盖。盖的作用是覆盖部分的蓄电池阵列的电路连接器总成，并保持和规划蓄电池阵列的感测线路布线。
背景技术
电气化车辆，例如混合动力电动车辆(HEV)，插电式混合动力电动车辆(PHEV)，纯电动车辆(BEV)，或燃料电池车辆不同于常规机动车辆，因为它们代替内燃发动机或者除了内燃发动机之外，由电机(即，电动马达和/或发电机)来提供动力。用于给电机提供动力的高压电流通常由高压蓄电池总成来供应。
蓄电池总成可以配备有一个或多个蓄电池阵列。每个蓄电池阵列包括相对于彼此支撑的多个蓄电池单元。蓄电池单元必须可靠地连接到彼此，以便实现操作电气化车辆所需的电压和功率水平。包括但不限于汇流条，单独的感测线路布线，用于规划感测线路布线的多个布线保持器，以及传感器的许多部件通常需要电连接蓄电池单元。
发明内容
根据本发明的示例性方面的一种蓄电池阵列除其他方面以外包括电路连接器总成和部分覆盖电路连接器总成的盖。盖包括槽。感测线路布线接收在槽内。
在上述蓄电池阵列的进一步非限制性实施例中，盖包括外表面，槽纵向延伸横跨外表面。
在任一上述蓄电池阵列的进一步非限制性实施例中，槽位于距盖的端壁第一距离处且蓄电池阵列的蓄电池接线柱位于距端壁第二距离处。
在任一上述蓄电池阵列的进一步非限制性实施例中，第一距离是比第二距离大的距离。
在任一上述蓄电池阵列的进一步非限制性实施例中，第一距离是比第二距离小的距离。
在任一上述蓄电池阵列的进一步非限制性实施例中，槽位于距盖的端壁第一距离处，第一距离设置在第一蓄电池接线柱距端壁的第二距离和第二蓄电池接线柱距端壁的第三距离之间。

具体实施方式
本发明涉及一种用于蓄电池阵列的电路连接器总成盖。盖的作用是覆盖部分的蓄电池阵列的电路连接器总成，以及保持和规划蓄电池阵列的感测线路布线。盖包括尺寸可以容纳感测线路布线的槽。感测线路布线可以经由槽沿蓄电池阵列的侧面或顶部规划，以减少蓄电池阵列所需的封装空间。这些和其他特征在下面的段落中进行更详细地讨论。
图1示意性地示出了用于电气化车辆12的动力传动系统10。虽然被描述为HEV，但是应当理解的是，在此所描述的概念不限于HEV且可以延伸至其它电气化车辆，包括但不限于PHEV和BEV。
在一个非限制性实施例中，动力传动系统10是使用第一驱动系统和第二驱动系统的动力分配动力传动系统。第一驱动系统包括发动机14和发电机18(即第一电机)的结合。第二驱动系统至少包括马达22(即第二电机)、发电机18和蓄电池总成24。在这个示例中，第二驱动系统被认为是动力传动系统10的电驱动系统。第一和第二驱动系统产生扭矩以驱动电气化车辆12的一组或多组车辆驱动轮28。
发动机14——其可以包括内燃发动机——和发电机18可以通过动力传输单元30——例如行星齿轮组——连接。当然，其它类型的动力传输单元，包括其它齿轮组和变速器，可以用于连接发动机14至发电机18。在一个非限制性实施例中，动力传输单元30是包括环形齿轮32，中心齿轮34和托架总成36的行星齿轮组。
发电机18可以由发动机14通过动力传输单元30来驱动以转变动能为电能。作为选择，发电机18可以用作马达以转变电能为动能，从而输出扭矩至连接到动力传输单元30的轴38。因为发电机18可操作地连接到发动机14，所以发动机14的速度可以由发电机18来控制。
动力传输单元30的环形齿轮32可以连接至轴40，轴40通过第二动力传输单元44连接至车辆驱动轮28。第二动力传输单元44可以包括具有多个齿轮46的齿轮组。其它动力传输单元也可以是适合的。齿轮46从发动机14传递扭矩至差速器48以最终提供牵引力至车辆驱动轮28。差速器48可以包括能够传递扭矩至车辆驱动轮28的多个齿轮。在一个实施例中，第二动力传输单元44通过差速器48机械地耦接至轮轴50以分配扭矩至车辆驱动轮28。
马达22也可以通过输出扭矩至也连接至第二动力传输单元44的轴52来驱动车辆驱动轮28。在一个实施例中，马达22和发电机18配合作为再生制动系统的一部分，在再生制动系统中，马达22和发电机18二者都可以用作马达以输出扭矩。例如，马达22和发电机18可以各自输出电力至蓄电池总成24。
蓄电池总成24是电气化车辆蓄电池总成的示例性类型。蓄电池总成24可以包括具有能够输出电力以操作马达22和发电机18的一个或多个蓄电池阵列的高压蓄电池组。其它类型的储能设备和/或输出设备也可以用于电驱动电气化车辆12。
图2和3示出了可以包含到电气化车辆——例如图1的电气化车辆12——中的蓄电池阵列60。例如，蓄电池阵列60可以是图1所示的蓄电池总成24的一部分。蓄电池总成24可以包括多个类似于蓄电池阵列60的蓄电池阵列，它们相对于彼此堆叠或分层。然而，本发明不限于具有特定数目的蓄电池阵列的蓄电池总成。
蓄电池阵列60可以包括封装在壳体64内的多个蓄电池单元62。在图2中用实线示出了壳体64，使得蓄电池单元62不可见。蓄电池单元62最佳地在图3中示出，图3用虚线示出了壳体64。蓄电池阵列60可以包括任意数量的蓄电池单元，并且本发明不限于图3所描绘的特定数目的单元。
蓄电池单元62沿纵轴线A在壳体64的相对壁66之间水平排列或堆叠。壳体64可以包括包围蓄电池阵列60的蓄电池单元62的多个壁66。虽然未示出，但是间隔件或分离件可以设置在壳体64内相邻的蓄电池单元62之间。
蓄电池单元62可以是袋型电池。在一个实施例中，蓄电池单元62是锂离子电池。然而，其他电化学蓄电池单元类型也是预期的。
在一个实施例中，形成壳体64的壁66之一包括盖68(见图2)，盖68也可以称为ICB(集成电路板)盖。盖68可以连接到一个或多个壁66。在另一个实施例中，盖68本身建立壳体64的壁66之一。盖68可以用多种方式连接到一个或多个壁66。例如，盖68可以螺栓连接、扣紧，或连接到蓄电池总成的托盘，而不是蓄电池阵列60。
盖68适于提供双重功能：覆盖电连接蓄电池阵列60的蓄电池单元62的部分的电路连接器总成70和保持连接蓄电池阵列60的电路连接器总成70至控制模块82的感测线路布线72。例如，盖68可以至少部分覆盖、包围和/或掩盖电路连接器总成70的集成电路板(ICB)74和/或一个或多个汇流条76(见图4)。电路连接器总成70可以由提供蓄电池阵列60内的电路连接的组件的任何组合组成。
除了覆盖部分的蓄电池阵列60，并且特别是覆盖部分的电路连接器总成70，盖68也可以保持蓄电池阵列60的感测线路布线72并规划感测线路布线72至控制模块82。在一个实施例中，盖68包括在盖68的外表面86上形成的槽84。感测线路布线72可以压合或扣到槽84中。槽84可以纵向延伸横跨外表面86的总长度L，并且可以平行于纵轴A延伸。在一个实施例中，外表面86面向远离壳体64的内部。换句话说，外表面86面向远离蓄电池单元62。
此外，盖68可以包括连接到槽84的第二槽81。在一个实施例中，第二槽81垂直于槽84。第二槽81可以接收感测线路布线72的布线分支83。布线分支83连接到电路连接器总成70的传感器80。由传感器80收集的信息可以通过布线分支83和感测线路布线72传输到控制模块82并由控制模块82监控。
盖68可以包括用于容纳电路连接器总成70的传感器80的切口(cut-out)78。换句话说，传感器80可以由盖68部分暴露，用于在盖68到位之后连接传感器80到感测线路布线72。感测线路布线72连接到控制模块82，用于监控蓄电池阵列60的功能。在一个非限制性实施例中，控制模块82是蓄电池电子控制模块。
继续参考图2和3，图4示出了部分的蓄电池阵列60的剖视图。该视图更好地示出了盖68、电路连接器总成70的组件的一些特征，以及盖68相对于电路连接器总成70的关系。
在一个实施例中，电路连接器总成70包括ICB 74，汇流条76(在图4中仅示出了一个)，感测线路布线72和传感器80(在图4中仅示出了一个)。电路连接器总成70提供了用于电连接蓄电池阵列60的蓄电池单元62的集成电路。电路连接器总成70可以以串联串或并联串的方式连接蓄电池单元62。
ICB 74电连接到每个蓄电池单元62的接线柱90。每个蓄电池单元62可以包括具有正和负极性的接线柱90。在本实施例中，正和负接线柱90设置在蓄电池单元62的相对侧上，使得每个蓄电池单元62的仅一个接线柱90连接到ICB 74。ICB 74可以包括用于接收接线柱90的开口92。以这种方式，接线柱90相对于蓄电池单元62支撑ICB 74。
ICB 74还建立了用于传感器80的安装平台。ICB 74可以包括用于容纳传感器80的开口94。在一个实施例中，传感器80是电压传感器。在另一个实施例中，传感器80是温度传感器。其它传感器也可以预期为在本发明的范围内。
布线分支83在第二槽81内从传感器80延伸到感测线路布线72。感测线路布线72从传感器80和/或ICB 74传输测量信号至控制模块82(见图2)。控制模块82可以编程为监测从传感器80和/或ICB 74接收的测量信号，例如防止蓄电池单元62的过充电。此外，控制模块82可以编程为执行与蓄电池阵列60相关的多种其他功能。
汇流条76也连接到接线柱90。汇流条76电连接接线柱90到相邻蓄电池单元的相邻接线柱，相邻蓄电池单元在图4中是蓄电池单元62的正后方。在一个实施例中，汇流条76连接具有相反极性(即，负到正或正到负)的相邻接线柱。汇流条76也电连接到ICB 74。
在一个实施例中，汇流条76是配置用于传导由蓄电池单元62产生的电力的冲压的相对薄的金属条。示例汇流条材料包括铜，黄铜或铝，尽管具有导电性的其它材料也可以是适合的。在一个实施例中，汇流条76是具有相对高电流容量的高电流汇流条。
在一个实施例中，盖68完全掩盖了汇流条76和接线柱90，并至少部分掩盖了ICB74。盖68可以位于蓄电池阵列60的蓄电池单元62的一侧上。在另一个实施例中，盖68可以位于蓄电池单元62的顶部上(见图5)。盖68的实际布置和定位将取决于蓄电池总成设计，封装考虑，以及其他因素。
在一个实施例中，盖68的槽84位于距盖68的端壁99第一距离D1处，第一距离D1是比端壁99和接线柱90之间的第二距离D2大的距离。在另一个实施例中，槽84设置在距盖68的端壁99第一距离D1处，第一距离D1是比端壁99和接线柱90之间的第二距离D2小的距离(见图6)。槽84的其它位置也是预期的。
图7示出了蓄电池阵列160的另一个实施例。在本发明中，相同的附图标记表示适用情况下相同的元件且附图标记加上100或其倍数表示被理解为包含相应的原始元件的相同的特征和好处的修改的元件。
在本实施例中，蓄电池单元162的正和负接线柱190设置在蓄电池单元162的同一侧上。盖168可以覆盖或掩盖汇流条176、接线柱190、以及部分的ICB 174。盖168包括用于规划感测线路布线172的槽184。在该非限制性实施例中，槽184位于距盖168的端壁199第一距离D1处，第一距离D1是比在端壁199和接线柱190之间延伸的距离D2、D3大的距离。作为选择，第一距离D1可以是比距离D2，D3小的距离(见图8)。在又一个实施例中，第一距离D1是距离D2和D3之间的距离(见图9)。
应当理解的是，在图2-9中所示的各种实施例并不一定按比例绘制，并且仅用于说明的目的。本发明的示例性槽盖可以减少规划感测线路布线所需的布线保持器的数量，增加蓄电池总成的封装空间，并简化蓄电池阵列总成。
虽然不同的非限制性实施例被示为具有特定的组件或步骤，但是本发明的实施例不限于那些特定的结合。使用来自于非限制性实施例的任何一个的一些组件或特征结合来自于其它非限制性实施例的任何一个的特征或组件是可能的。
应当理解的是，贯穿几个附图，同样的附图标记标识相应的或相似的元件。应当理解的是，虽然在这些示例性实施例中公开和示出了特定的组件布置，但是其它布置也可以受益于本发明的教导。
前面的描述应当被解释为说明性的而不是限制性的意义。本领域普通技术人员可以理解，在本发明的范围内可以作某些修改。因为这些理由，应该研究以下权利要求来确定本发明的真实范围和内容。
