Description

汇流装置及储能装置
本申请要求于2024年7月2日提交中国专利局、申请号为2024108752289、公开名称为汇流装置及储能装置的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及储能设备技术领域，尤其涉及一种汇流装置及储能装置。
背景技术
相关技术中，为了节省将多个线束固定于汇流板时线束在汇流板上占用的空间，一般将多个线束双排固定于汇流板上。具体地，汇流板上通常设置有沿汇流板的厚度方向贯穿汇流板的通孔，双排线束分别位于汇流板的沿上述厚度方向的两侧，螺钉的螺杆通过上述通孔从汇流板的第一侧穿至第二侧，然后在穿至第二侧的螺杆上套上螺母，这样，通过旋紧螺母将双排线束及汇流板夹持于螺母和螺钉的螺帽之间，即可实现将双排线束固定于汇流板上的目的。
然而，通过上述描述可以看出，由于固定双排线束时需要旋紧螺母，为了便于旋紧螺母势必需要在汇流板的第二侧、也即汇流板的背离螺帽的一侧预留扳手进入的空间，因此，将造成空间上的浪费。
发明内容
本申请实施例公开了一种汇流装置及储能装置，其能够在节省空间的同时还可以降低将线束双排固定于汇流件时在操作上的难度。
为了实现上述目的，第一方面，本申请公开一种汇流装置，包括：
汇流件，所述汇流件上设置有沿第一方向贯穿所述汇流件的第一贯穿部；
压紧件，所述压紧件沿所述第一方向可活动地设置于所述汇流件且位于所述汇流件的沿所述第一方向的一侧，所述压紧件与所述汇流件之间沿所述第一方向形成夹设间隙，所述夹设间隙用于夹设第一线束的接线鼻，所述压紧件上设置有与所述第一贯穿部沿所述第一方向相对的第一螺纹孔；以及，
旋紧件，所述旋紧件包括第一螺杆及连接于所述第一螺杆的第一螺帽，所述第一螺杆沿所述第一方向可活动地穿设于所述第一贯穿部且螺纹连接于所述第一螺纹孔，所述第一螺帽限位于所述汇流件的背离所述压紧件的一侧，所述第一螺帽与所述汇流件之间用于夹设第二线束的接线鼻。
第二方面，本申请公开一种储能装置，包括：
壳体，所述壳体形成有容置腔；
电池包，所述电池包设置于所述容置腔内；
上述第一方面中任一种所述的汇流装置，所述汇流件绝缘连接于所述壳体的安装部，所述压紧件沿所述第一方向位于所述汇流件及所述安装部之间且与所述安装部之间具有间隙；
第一线束；以及，
第二线束，所述第二线束及所述第一线束均连接于所述电池包，所述第一线束的接线鼻夹设于所述夹设间隙、所述第二线束的接线鼻夹设于所述第一螺帽及所述汇流件之间。
与现有技术相比，本申请具有如下有益效果：
由于压紧件沿第一方向可活动地设置于汇流件且位于汇流件的沿第一方向的一侧，汇流件上设置有沿第一方向贯穿汇流件的第一贯穿部，压紧件上设置有与第一贯穿部沿第一方向相对的第一螺纹孔，第一螺杆沿第一方向可活动地穿设于第一贯穿部且螺纹连接于第一螺纹孔，第一螺帽限位于汇流件的背离压紧件的一侧，因此，在第一线束的接线鼻设置于夹设间隙、第二线束的接线鼻设置于汇流件的背离压紧件的一侧的前提下，仅仅在汇流件的第一螺帽所在的一侧拧动第一螺帽，即可实现使得压紧件沿第一方向朝靠近汇流件的方向运动的目的，进而可以实现将第一线束及第二线束沿第一方向双排固定于汇流件的目的，相比于相关技术来说，无需在汇流件的背离第一螺帽的一侧安装螺母并拧动螺母，因此，一方面，可以不必在汇流件的背离第一螺帽的一侧预留扳手进入的空间，可以达到节省空间的目的，另一方面，由于无需在汇流件的背离第一螺帽的一侧安装螺母，因此，也可以在一定程度上降低将第一线束及第二线束沿第一方向双排固定于汇流件时在操作上的难度。

下面将结合实施例和附图对本申请的技术方案作进一步的说明。
图1是本申请一实施例提供的一种汇流装置100的结构示意图，图2是图1中的汇流装置100的爆炸图，图3是图1中的汇流装置100在沿着Y轴方向视角下的结构示意图。
参见图1、图2及图3，汇流装置100包括：汇流件1、压紧件2及旋紧件3，其中，汇流件1上设置有沿第一方向(图2中X轴方向)贯穿汇流件1的第一贯穿部11，压紧件2沿第一方向可活动地设置于汇流件1且位于汇流件1的沿第一方向的一侧(图1中汇流件1的左侧)，压紧件2与汇流件1之间沿第一方向形成夹设间隙21，夹设间隙21用于夹设第一线束400的接线鼻，压紧件2上设置有与第一贯穿部11沿第一方向相对的第一螺纹孔22，旋紧件3包括第一螺杆31及连接于第一螺杆31的第一螺帽32，第一螺杆31沿第一方向可活动地穿设于第一贯穿部11且螺纹连接于第一螺纹孔22，第一螺帽32限位于汇流件1的背离压紧件2的一侧(图2中汇流件1的右侧)，第一螺帽32与汇流件1之间用于夹设第二线束500的接线鼻。
本实施例中，在需要将第一线束400及第二线束500沿第一方向双排固定于汇流件1时，由于压紧件2沿第一方向可活动地设置于汇流件1且位于汇流件1的沿第一方向的一侧，因此，首先可以使得压紧件2沿第一方向朝远离汇流件1的方向运动，使得压紧件2与汇流件1之间沿第一方向形成夹设间隙21，接着，可以将第一线束400的接线鼻设置于夹设间隙21、将第二线束500的接线鼻设置于汇流件1的背离压紧件2的一侧，以使得第一线束400的接线鼻及第二线束500的接线鼻分别位于汇流件1的沿第一方向的两侧。
接着，由于汇流件1上设置有沿第一方向贯穿汇流件1的第一贯穿部11，压紧件2上设置有与第一贯穿部11沿第一方向相对的第一螺纹孔22，因此，可以将第一螺杆31沿第一方向可活动地穿设于第一贯穿部11且螺纹连接于第一螺纹孔22，并将第一螺帽32限位于汇流件1的背离压紧件2的一侧，在此基础上，当拧动第一螺帽32时，可以使得压紧件2沿第一方向朝靠近汇流件1的方向运动，进而可以实现将第一线束400的接线鼻夹设于汇流件1与压紧件2之间的夹设间隙21、将第二线束500的接线鼻夹设于第一螺帽32与汇流件1之间的目的，从而可以实现将第一线束400及第二线束500沿第一方向双排固定于汇流件1的目的。
其中，由于压紧件2沿第一方向可活动地设置于汇流件1且位于汇流件1的沿第一方向的一侧，汇流件1上设置有沿第一方向贯穿汇流件1的第一贯穿部11，压紧件2上设置有与第一贯穿部11沿第一方向相对的第一螺纹孔22，第一螺杆31沿第一方向可活动地穿设于第一贯穿部11且螺纹连接于第一螺纹孔22，第一螺帽32限位于汇流件1的背离压紧件2的一侧(图2中汇流件1的右侧)，因此，在第一线束400的接线鼻设置于夹设间隙21、第二线束500的接线鼻设置于汇流件1的背离压紧件2的一侧的前提下，仅仅在汇流件1的第一螺帽32所在的一侧(图2中汇流件1的右侧)拧动第一螺帽32，即可实现使得压紧件2沿第一方向朝靠近汇流件1的方向运动的目的，进而可以实现将第一线束400及第二线束500沿第一方向双排固定于汇流件1的目的，相比于相关技术来说，无需在汇流件1的背离第一螺帽32的一侧(图2中汇流件1的左侧)安装螺母并拧动螺母，因此，一方面，可以不必在汇流件1的背离第一螺帽32的一侧预留扳手进入的空间，可以达到节省空间的目的，另一方面，由于无需在汇流件1的背离第一螺帽32的一侧安装螺母，因此，也可以在一定程度上降低将第一线束400及第二线束500沿第一方向双排固定于汇流件1时在操作上的难度。
需要说明的是，上述汇流件1及压紧件2均可以为如图1所示的板状结构，当然，汇流件1及压紧件2也可以为其他形状的结构，本实施例对此不作限定。
上述第一贯穿部11可以为沿第一方向贯穿汇流件1的通孔，当然，第一贯穿部11也可以为沿第一方向贯穿汇流件1的U形豁口等，本实施例对第一贯穿部11不作限定。
另外，上述旋紧件3可以为普通意义上的螺钉，当然，旋紧件3也可以为跟螺钉结构类似、功能也类似的其他结构，本实施例对此不作限定。
当旋紧件3为螺钉时，旋紧件3可以包括但不限于一字螺钉、十字槽螺钉或者内六角螺钉等，本实施例对此不作限定。
为了使得汇流装置100可以汇流更多的第一线束400及第二线束500，在一些实施例中，参见图1及图2，第一贯穿部11的数量为多个，多个第一贯穿部11沿第二方向(图2中Y轴方向)间隔排布于汇流件1。
当第一贯穿部11的数量为多个且多个第一贯穿部11沿第二方向间隔排布于汇流件1时，由于第一螺纹孔22与第一贯穿部11沿第一方向相对设置，第一螺杆31沿第一方向可活动地穿设于第一贯穿部11且螺纹连接于第一螺纹孔22，因此，第一螺纹孔22的数量也将为多个且多个第一螺纹孔22沿第二方向间隔排布于压紧件2，旋紧件3的数量也将为多个且穿设于对应的第一贯穿部11中。如此一来，当对应每个第一贯穿部11在汇流件1沿第一方向的两侧分别设置第一线束400和第二线束500时，显然，通过拧动对应的第一螺帽32，即可实现将对应的第一线束400和对应的第二线束500沿第一方向双排固定于汇流件1的目的，通过拧动多个第一螺帽32，即可实现将多个第一线束400和多个第二线束500沿第一方向双排固定于汇流件1的目的，进而可以使得汇流装置100实现汇流更多的第一线束400及第二线束500的目的。
其中，上述第一贯穿部11的数量可以为如图2所示的六个，当然，也可以为七个、八个或者九个等，本实施例对此不作限定。
需要说明的是，上述压紧件2沿第一方向可活动地设置于汇流件1的实现方式具有多种，在其中一种可能的实现方式中，参见图2及图3，汇流装置100还包括连接件4，汇流件1上设置有沿第一方向(图2中X轴方向)贯穿汇流件1的第二贯穿部12，连接件4沿第一方向可活动地穿设于第二贯穿部12且与压紧件2连接，连接件4的部分结构41限位于汇流件1的背离压紧件2的一侧(图3中汇流件1的右侧)，其中，该部分结构41与压紧件2沿第一方向的间距为J，汇流件1沿第一方向的厚度为T，J＞T。
由于连接件4沿第一方向可活动地穿设于第二贯穿部12且与压紧件2连接，连接件4的部分结构41限位于汇流件1的背离压紧件2的一侧，又由于J＞T，因此，当拧动第一螺帽32使得压紧件2受到沿第一方向朝远离汇流件1方向的外力时，压紧件2可以带动该部分结构41沿第一方向朝靠近汇流件1方向运动直至该部分结构41抵靠于汇流件1，当拧动第一螺帽32使得压紧件2受到沿第一方向朝靠近汇流件1方向的外力时，压紧件2可以带动该部分结构41沿第一方向朝远离汇流件1方向运动直至压紧件2抵靠于汇流件1，在压紧件2沿第一方向朝靠近或者远离汇流件1运动的过程中，可以实现上述将压紧件2沿第一方向可活动地设置于汇流件1的目的。
可见，当连接件4沿第一方向可活动地穿设于第二贯穿部12且与压紧件2连接，连接件4的部分结构41限位于汇流件1的背离压紧件2的一侧时，通过拧动第一螺帽32，在连接件4与第二贯穿部12相互配合导向的作用下，可以实现使得压紧件2沿第一方向可活动地设置于汇流件1的目的，无需设计复杂的结构，实现方式非常简单，因此，可以在一定程度上降低汇流装置100的成本。
当然，压紧件2也可以通过其他方式实现沿第一方向可活动地设置于汇流件1的目的，本实施例对此不作限定。
需要说明的是，上述连接件4的数量可以为如图2所示的三个，当然，也可以为四个或者五个等，本实施例对此不作限定。与之相对应地，上述第二贯穿部12的数量也可以为三个、四个或者五个等，本实施例对此不作限定。
还需要说明的是，上述第二贯穿部12设置于汇流件1只是本实施例示出的一种可能的设置方式，当然，第二贯穿部12也可以设置于压紧件2，本实施例对此不作限定。当第二贯穿部12设置于压紧件2时，连接件4可以与汇流件1连接，连接件4的部分结构41可以限位于压紧件2的背离汇流件1的一侧。
其中，第二贯穿部12的结构可以与上述第一贯穿部11的结构相同或者类似，具体可参照上述实施例中对第一贯穿部11的描述，本实施例在此不再赘述。
在一些实施例中，参见图2及图3，连接件4包括第二螺杆42及连接于第二螺杆42的第二螺帽，第二螺帽为上述的部分结构41，压紧件2上与第二贯穿部12沿第一方向相对的位置设置有第二螺纹孔23，第二螺杆42螺纹连接于第二螺纹孔23，第二螺帽限位于汇流件1的背离压紧件2的一侧。
其中，当连接件4包括第二螺杆42及连接于第二螺杆42的第二螺帽时，可以在保证能够与第二贯穿部12相互配合导向，以在拧动第一螺帽32时实现使得压紧件2沿第一方向可活动地设置于汇流件1的目的基础上，尽可能的简化连接件4的结构，达到降低连接件4的成本的目的。
当然，连接件4也可以为其他可能的结构，本实施例对此不作限定。当连接件4包括第二螺杆42及连接于第二螺杆42的第二螺帽时，连接件4的结构可以与上述旋紧件的结构类似，本实施例对此不作限定。
在一些实施例中，参见图2及图3，第二螺杆42的长度为L，L＝T+c，0.5mm＜c＜3mm。
经发明人长期研究发现，当L＝T+c，0.5mm＜c＜3mm时，可以保证第二螺杆42能够穿过汇流件1连接于压紧件2上的第二螺纹孔23的同时，还能够允许压紧件2与汇流件1沿第一方向具有间隙，进而为压紧件2沿第一方向可活动地设置于汇流件1提供了保证。
并且，通过使得0.5mm＜c＜3mm，既不会使得压紧件2与汇流件1沿第一方向的间隙过大导致汇流装置100的体积过大，也不会使得压紧件2与汇流件1沿第一方向的间隙过小导致压紧件2沿第一方向可活动的行程过小。
具体地，c可以为0.51mm，1mm或者2.9mm等，只需使得0.5mm＜c＜3mm即可，本实施例对c不作限定。
在一些实施例中，参见图2及图3，第二螺纹孔23为盲孔。当第二螺纹孔23为盲孔时，一方面，可以避免第二螺杆42穿出压紧件2的情况发生，使得压紧件2的表面更加的平整。另一方面，在将第二螺杆42螺纹连接于第二螺纹孔23的过程中，由于当第二螺杆42抵靠于第二螺纹孔23的孔底时将无法继续拧动第二螺杆42且此时第二螺杆42安装到位，因此，可以通过能否拧动第二螺杆42来判断第二螺杆42是否安装到位，使得第二螺杆42是否安装到位变得可感知。
在一些实施例中，参见图2、图3及图4，图4是图3中的压紧件2的结构示意图，压紧件2包括：固定部24、倾斜部25及压紧部26，其中，汇流件1上设置有沿第一方向贯穿汇流件1的第二贯穿部12，连接件4沿第一方向可活动地穿设于第二贯穿部12且与固定部24连接，固定部24与汇流件1之间沿第一方向形成活动间隙241，倾斜部25的第一端与固定部24连接、第二端朝远离汇流件1的方向(图3中向左)倾斜，压紧部26连接于倾斜部25的第二端，压紧部26与汇流件1之间形成夹设间隙21，夹设间隙21沿第一方向的宽度大于活动间隙241沿第一方向的宽度。
由于连接件4沿第一方向可活动地穿设于第二贯穿部12且与固定部24连接，因此，可以使得固定部24沿第一方向可朝靠近或者远离汇流件1的方向运动，进而可以使得压紧部26沿第一方向可朝靠近或者远离汇流件1的方向运动。当压紧部26沿第一方向朝靠近汇流件1的方向运动过多时，将导致夹设间隙21消失，进而导致将第一线束400的接线鼻插设于夹设间隙21中变的比较困难。
本实施例通过使得夹设间隙21沿第一方向的宽度大于活动间隙241沿第一方向的宽度，可以使得当固定部24沿第一方向朝靠近汇流件1的方向运动时，固定部24会先于压紧部26抵靠于汇流件1，这么一来，当固定部24抵靠于汇流件1时，压紧部26将无法继续沿第一方向朝靠近汇流件1的方向运动，使得压紧部26无法抵靠于汇流件1，进而可以避免出现夹设间隙21消失的情况发生，从而可以避免因夹设间隙21消失导致将第一线束400的接线鼻插设于夹设间隙21中变的比较困难的情况发生。
需要说明的是，上述第二贯穿部12设置于汇流件1，连接件4沿第一方向可活动地穿设于第二贯穿部12且与固定部24连接只是本实施例给出的一种可能的实现方式中，在另一种可能的实现方式中，第二贯穿部12也设置于固定部24，连接件4也可以沿第一方向可活动地穿设于第二贯穿部12且与汇流件1连接，本实施例对此不作限定。
考虑能否容易、便捷的将第一线束400的接线鼻插设于夹设间隙21直接影响着汇流装置100的使用体验，为了提高汇流装置100的使用体验，在一些实施例中，参见图2及图5，图5是图2中的汇流件1在另一视角下的结构示意图，汇流装置100还包括导向组件5，导向组件5位于夹设间隙21中，导向组件5用于引导第一线束400的接线鼻插设于夹设间隙21中。
由于导向组件5位于夹设间隙21中，因此，通过设置导向组件5，在导向组件5的引导作用下，可以使得第一线束400的接线鼻非常容易、便捷的插设于夹设间隙21，从而可以提高汇流装置100的使用体验。
其中，上述导向组件5的实现方式具有多种，在其中一种可能的实现方式中，参见图2及图5，导向组件5包括：第一引导件51及第二引导件52，其中，第二引导件52及第一引导件51均设置于夹设间隙21且位于第一贯穿部11的沿第二方向(图2中Y轴方向)的两侧以形成导向缝隙511，导向缝隙511用于引导第一线束400的接线鼻通过导向缝隙511插设于夹设间隙21中。
由于第二引导件52及第一引导件51均设置于夹设间隙21且位于第一贯穿部11的沿第二方向的两侧，又由于第二引导件52及第一引导件51之间形成导向缝隙511，因此，当需要将第一线束400的接线鼻插设于夹设间隙21中时，只需首先将第一线束400的接线鼻插设于导向缝隙511，然后沿着导向缝隙511的延伸方向推动第一线束400的接线鼻，即可实现将第一线束400的接线鼻插设于夹设间隙21中的目的，实现方式非常的简单。
其中，上述第二引导件52及第一引导件51可以为如图5所示的条状结构，当然，第二引导件52及第一引导件51也可为其他形状的结构，比如，可以为板状结构等，本实施例对此不作限定。
在一些实施例中，参见图5及图6，图6是图1中的汇流装置100省略掉第一线束400及第二线束500后的结构示意图，第一引导件51及第二引导件52均沿第三方向(图5中Z轴方向)延伸，导向缝隙511用于引导第一线束400的接线鼻通过导向缝隙511沿第三方向插设于夹设间隙21中，第一引导件51及第二引导件52中的至少一者沿第三方向冒出于汇流件1和/或压紧件2。
通过使得第一引导件51及第二引导件52中的至少一者沿第三方向冒出于汇流件1和/或压紧件2，可以使得第一引导件51及第二引导件52共同形成的导向缝隙511的开口沿第三方向冒出于汇流件1和/或压紧件2，如此设置，可以使得第一引导件51及第二引导件52共同形成的导向缝隙511可以在第一线束400的接线鼻进入到夹设间隙21中之前提前通过导向缝隙511进行导向，如此一来，可以使得将第一线束400的接线鼻插设于夹设间隙21中变得更加的方便快捷。
其中，第一引导件51及第二引导件52中的至少一者沿第三方向冒出于汇流件1和/或压紧件2的高度可以为3mm至8mm内的任一数值，经发明人研究发现，当第一引导件51及第二引导件52中的至少一者沿第三方向冒出于汇流件1和/或压紧件2的高度为3mm至8mm的范围内时，可以使得第一引导件51及第二引导件52共同形成的导向缝隙511的导向作用更好。
具体的，第一引导件51及第二引导件52中的至少一者沿第三方向冒出于汇流件1和/或压紧件2的高度可以为3mm、5.5mm或者8mm等，只需位于3mm至8mm的范围内即可，本实施例对此不作限定。
在一些实施例中，参见图5，第一引导件51及第二引导件52均设置于汇流件1。
当第一引导件51及第二引导件52均设置于汇流件1时，可以使得第一引导件51及第二引导件52均集成于汇流件1，如此设置，在装配汇流装置100时，无需单独将第一引导件51及第二引导件52装配于夹设间隙21中，只需将汇流件1和压紧件2装配起来，第一引导件51及第二引导件52将自动位于夹设间隙21中，因此，可以降低汇流装置100的装配难度。
当然，上述第一引导件51及第二引导件52均设置于汇流件1只是本实施例给出的一种可能的设置方式，当然，第一引导件51及第二引导件52也可以均设置于压紧件2，或者，第一引导件51及第二引导件52中的一者设置于压紧件2、另一者设置于汇流件1等，本实施例对此不作限定。
需要说明的是，当第一引导件51及第二引导件52均设置于汇流件1时，第一引导件51及第二引导件52均可以通过焊接的方式设置于汇流件1，当然，也可以通过其他方式设置于汇流件1，本实施例对此不作限定。
在一些实施例中，参见图3、图6及图7，图7是图6中的汇流装置100在沿着Y轴方向视角下的结构示意图，第一引导件51及第二引导件52沿第一方向的厚度均为d，第一线束400的接线鼻沿第一方向的厚度为k，k＞d。
当第一线束400的接线鼻沿第一方向的厚度k大于第一引导件51及第二引导件52沿第一方向的厚度d时，可以保证第一线束400的接线鼻可以紧密的夹紧在压紧件2及汇流件1之间，可以避免出现第一引导件51及第二引导件52支撑在压紧件2及汇流件1之间导致第一线束400的接线鼻无法夹紧在压紧件2及汇流件1之间的情况发生。
在一些实施例中，参见图1，汇流装置100还包括：绝缘件6，绝缘件6连接于汇流件1的压紧件2所在的一侧(图1中汇流件1的左侧)、避让开压紧件2且位于夹设间隙21之外，绝缘件6用于连接于安装部2002时使安装部2002分别与汇流件1及压紧件2中的任一者隔开。
由于绝缘件6连接于汇流件1的压紧件2所在的一侧、避让开压紧件2且位于夹设间隙21之外，因此，当绝缘件6连接于安装部2002时，通过绝缘件6可以使得安装部2002分别与汇流件1及压紧件2中的任一者隔开，这么一来，可以避免汇流装置100上的电流传导至安装部2002的情况发生，从而可以使得汇流装置100更加的安全。
具体地，以汇流装置100应用于储能装置1000中为例，上述安装部2002可以理解为储能装置1000的中控柜，显然，通过设置绝缘件6，绝缘件6可以避免汇流装置100上的电流传导至中控柜导致中控柜带电的情况发生，而当中控柜带电时可能会对人员的人生安全造成威胁，因此，通过设置绝缘件6，可以使得汇流装置100更加的安全。
其中，上述绝缘件6可以为绝缘子，绝缘件6的数量可以为一个、两个或者三个等，本实施例对此不作限定。
图8是本申请一实施例提供的一种储能装置1000的结构示意图，参见图1及图8，储能装置1000包括：壳体200、电池包300、汇流装置100、第一线束400及第二线束500，其中，壳体200形成有容置腔2001，电池包300设置于容置腔2001内，汇流件1绝缘连接于壳体200的安装部2002，压紧件2沿第一方向位于汇流件1及安装部2002之间且与安装部2002之间具有间隙，第二线束500及第一线束400均连接于电池包300，第一线束400的接线鼻夹设于夹设间隙21、第二线束500的接线鼻夹设于第一螺帽32及汇流件1之间。
其中，汇流装置100的结构可以与上述实施例中任一种所述的汇流装置100的结构相同，并能带来相同或者类似的有益效果，具体可参照上述实施例中对汇流装置100的描述，本实施例在此不再赘述。
本实施例中，由于汇流装置100不必在汇流件1的背离第一螺帽32的一侧(图8中汇流件1的左侧)预留扳手进入的空间，也无需在汇流件1的背离第一螺帽32的一侧(图8中汇流件1的左侧)安装螺母，因此，可以在节省空间的同时降低将第一线束400及第二线束500沿第一方向双排固定于汇流件1时在操作上的难度。基于此，当该汇流装置100应用于储能装置1000时，一方面，可以使得储能装置1000的结构更加的紧凑，另一方面，该储能装置1000在将第一线束400及第二线束500沿第一方向双排固定于汇流件1时的操作难度也较低。
需要说明的是，上述安装部2002可以为储能装置1000的中控柜等，本实施例对此不作限定。
考虑到电池包300通常具有正极线束及负极线束，因此，汇流装置100的数量可以设置为两个，其中一个可以用于汇流正极线束、另一个可以用于汇流负极线束。
其中，由于第一线束400及第二线束500均连接于同一个汇流装置100，而同一个汇流装置100要么只汇流正极线束，要么只汇流负极线束，因此，上述第一线束400及第二线束500可以理解为均为正极线束，或者，均为负极线束。
本申请还提供一种储能系统2000，参见图9，图9为本申请一实施例的储能系统2000的结构示意图，且本申请图9实施例以发/配电侧共享储能场景为例进行说明，本申请储能装置1000并不限定于其发/配电侧储能场景。

可选地，所述第一电能转换装置4000及所述第二电能转换装置5000可将太阳能、光能、风能、热能、潮汐能、生物质能及机械能等中的至少一种转换为电能。
储能装置1000的数量可以为多个，多个储能装置1000相互串联或并联，多个储能装置1000采用隔离板(图未示)进行支撑及电连接。本实施例中，“多个”是指两个及两个以上。储能装置1000外部还可以设有储能箱，用于收容储能装置1000。
可选地，储能装置1000可包括但不限于单体电池、电池模组、电池包、电池系统等。本申请实施例提供的储能装置1000的实际应用形态可以为但不限于为所列举产品，还可以是其他应用形态，本申请实施例不对储能装置1000的应用形态做严格限制。本申请实施例仅以储能装置1000为多芯电池为例进行说明。当该储能装置1000为单体电池时，储能装置1000可以为圆柱电池、方形电池等中的至少一种。
