具体实施方式
下面通过具体的实施例并结合附图对本申请做进一步的详细描述。
如图4所示，本申请实施例中提供了一种电池包，电池包包括多个电池模组1，下箱体2和上盖3，上盖3与下箱体2配合并密封连接，以形成容纳腔，多个电池模组1容纳于容纳腔内。
如图2和3所示，电池模组1包括汇流条组件12以及两个以上(包括两个)的电池单元11，本实施例中，两个以上的电池单元11在竖直方向上相互堆叠。
如图5所示，电池单元11包括壳体111、电极组件113和盖板116。电极组件113容置在壳体111内，盖板116覆盖在壳体111的开口。电极组件113通过卷绕或层叠极片以及隔板形成，极片的端部形成极耳114，极耳114通过连接构件115与盖板116上的电极端子112相连。电极端子112包括正极端子和负极端子，正极端子与电极组件113的正极片电连接，负极端子与电极组件113的负极片电连接。正极端子和负极端子可以均设置在盖板116上。
本实施例中，汇流条组件12用于附接在沿竖直方向相互堆叠的多个电池单元11上(如图2所示)。如图3所示，本申请实施例提供的电池模组1包括上述的多个电池单元11和汇流条组件12。可以理解的是，多个电池单元11指的是有两个以上(包括两个)的电池 单元11。本申请实施例中，电池模组1可以是平躺式的电池模组或侧躺式的电池模组，在竖直方向上，多个电池单元11包括上层电池单元和下层电池单元。本申请实施例以平躺式电池模组为例进行说明，但是本领域技术人员可以理解的是，本申请实施例涉及的汇流条组件12也可以用于侧躺式电池模组。本申请实施例中的竖直方向指的是电池模组安装完成后，放置于水平地面上，与水平地面相垂直的方向。
如图1所示，汇流条组件12包括上层汇流条121、下层汇流条122和绝缘构件123。如图3所示，上层汇流条121用于附接在上层相邻两个电池单元11的电极端子112上，以使上层相邻两个电池单元11实现串联。下层汇流条122用于附接在下层相邻两个电池单元11的电极端子112上，以使下层相邻两个电池单元11实现串联。通过多个汇流条组件，从而将多个电池单元11串联。上层汇流条121和下层汇流条122之间通过绝缘构件123相连。
该绝缘构件123可以与上层汇流条121和下层汇流条122一体注塑成型，也可以通过其他的方式成型。优选的是，绝缘构件123分别与上层汇流条121和下层汇流条122一体注塑成型。
在生产过程中，如图2和图3所示，除了两端的电池单元11最靠近外侧的电极端子112之外，对于位于中间部分的电极端子112，将汇流条组件12安装，上层汇流条121对应上层相邻两个电池单元11的电极端子112(一端正极端子和一端负极端子)上，下层汇流条122对应下层相邻两个电池单元11的电极端子112上(一端正极端子和一端负极端子)。由于绝缘构件123的隔离，避免了上层汇流条121和下层汇流条122之间发生短路，进而避免了发生安全事故。
参照图1，作为一种示例，绝缘构件123包括主体部123c，该主体部123c位于上层汇流条121和下层汇流条122之间，以将上层汇流条121和下层汇流条122隔离。
由于温度的冷热变化，在电池单元11上有时会产生一定量的冷凝水，当产生冷凝水时，容易将上层汇流条121和下层汇流条122之间导通。为了避免该问题的发生，优选的是，在绝缘构件123的上述主体部123c上设置有导流槽123d，主体部123c的远离电池单元11 的一侧表面凸出于上层汇流条121的远离电池单元11的一侧表面，主体部123c的靠近上层汇流条121的一端设置有上述导流槽123d，导流槽123d具有倾斜的导流面123e。这样，导流槽123d刚好可以承接上层汇流条121上流下的冷凝水，冷凝水就能够沿着导流面123e流下，而不会流到下层汇流条122上。
优选地，如图1所示，导流面123e沿着远离汇流条组件12在竖直方向上的中轴线的方向向下倾斜。也就是说，在汇流条组件12内侧指向汇流条组件12外侧的方向上，导流面123e向下倾斜，这样不仅能将冷凝水向下层汇流条122的旁边引流，还能由汇流条组件12的内侧向外侧引流，进一步避免了冷凝水滴落到下层汇流条122上。
进一步地，可以设置导流槽123d的数量是两个，两个导流槽123d轴对称设置，并且汇流条组件12在竖直方向上的中轴线为对称轴。这样，在上层汇流条121上的冷凝水就能够沿着两个导流槽123d分别流向汇流条组件12的两侧，而不会流到下层汇流条122上。上层汇流条121上的冷凝水沿着两个向下倾斜的导流面123e流下来，避免了冷凝水流到下层汇流条122上引起上层汇流条121和下层汇流条122的短路。
如图1所示，上述绝缘构件123还可以包括上限位部123a和下限位部123b，上限位部123a夹持上层汇流条121，下限位部123b夹持下层汇流条122，上述主体部123c位于上层汇流条121和下层汇流条122之间。上限位部123a和下限位部123b均可以是长条状，其成型或加工都更为便利。通过设置上限位部123a和下限位部123b，能够防止上层汇流条121和下层汇流条122与绝缘构件123发生脱落，使上层汇流条121和下层汇流条与122与绝缘构件123的连接更加稳定。
进一步地，绝缘构件123的材质为塑胶，上述的限位部123a、下限位部123b、主体部123c、导流槽123d和导流面123e均直接一次注塑成型，无需二次加工，省时省力。
如图2所示，电池模组1中位于一端最外侧的电极端子112分别通过引出端子13引出至外部，电池模组1中位于另一端最外侧电极 端子112利用现有技术中的汇流条14连接，电池模组的两端通过固定板16进行固定。对于中间部分的电极端子112，上层汇流条121附接在上层相邻两个电池单元11的电极端子112上，下层汇流条122附接在下层相邻两个电池单元11的电极端子112上。由于绝缘构件123的隔离，避免了上层汇流条121和下层汇流条122之间发生短路，进而避免了安全事故的发生。
上述电池模组1还包括柔性电路板15，柔性电路板15可以与汇流条组件12粘接固定，如图2所示，该柔性电路板15用于对电池单元11的温度、电压等参数进行检测。柔性电路板15上设置有定位孔151，绝缘构件123上设置有定位柱123f，定位孔151和定位柱123f相配合(参照图2和图3)。为了避免柔性电路板15发生移动，设置该定位柱123f，对柔性电路板15进行定位。而且，如果柔性电路板15粘接在汇流条组件12上，粘接面积不足也会容易脱落，通过设置该定位柱123f增大了粘接面积，使粘接更可靠。
本实施例中，电池单元11包括长方体状的壳体111和覆盖壳体111的开口的盖板116，在将电池模组1安装至电池箱时，壳体111的垂直于盖板116所在平面的面为电池模组1的安装面，参照图2。
另请参照图2，也就是说，壳体111的长度L和高度H所在的面(垂直于盖板116所在的面)为电池模组1的安装面，即，电池模组1为平躺式电池模组。或壳体111的宽度W和高度H所在的面(垂直于盖板116所在的面)为电池模组1的安装面，即，电池模组1为侧躺式电池模组。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
