本发明的实施方式
本申请实施例提供一种电池包及车辆。
图1是本申请的实施例提供的电池包的一个实施例的结构示意图。图2是图1的电池包去除外壳后沿A-A方向的剖视图。如图1和图2所示,电池包100包括支撑板140、电池组件110和支撑组件120,电池组件110设于支撑板140的一侧板面141,电池组件110包括沿电池包100的高度方向Z层叠设置的多个电池模组111,支撑组件120包括分布于电池组件110沿第一方向X两侧的支撑结构121,支撑组件120的两个支撑结构121设置为对电池组件110的多个电池模组111进行支撑。
其中,电池模组111包括沿第一方向X分布的两个端板1111,以及,设于两个端板1111之间的电芯(图中未示出),高度方向Z和第一方向X呈夹角。具体地,电池模组111包括多个电芯,且多个电芯沿第一方向X堆叠放置于两个端板1111之间。两个端板1111可以通过侧板连接,也可以通过连接带连接,从而使两个端板1111夹紧多个电芯。其中,位于最下方的电池模组111的端板1111支撑于支撑板140,以使电池组件110整体设于支撑板140的板面141。
如图2和图3所示,支撑结构121包括沿高度方向Z设置的多个支撑件1211。在高度方向Z上相邻的两个端板1111中,下方的端板1111通过支撑件1211支撑上方的端板1111,从而使电池组件110的相邻两个电池模组111中,上方的电池模组111通过支撑件1211支撑于下方的电池模组111上。也即,电池组件110的多个电池模组111沿第一方向X一侧的端板1111与同一侧的多个支撑件1211交替支撑于支撑板140的板面141。
由此,在对多个电池模组111进行堆叠时,可以先将第一个电池模组111的两个端板1111支撑于支撑板140的板面141,然后,将两个支撑件1211一一对应支撑于第一个电池模组111的两个端板1111上,然后,再将第二电池模组111堆放于第一个电池模组111上,并使电池模组111的两个端板1111支撑于两个支撑件1211上。之后,可以采用同样的方式对第三、第四甚至更多个电池模组111进行堆叠。
由于多个电池模组111通过支撑结构121进行支撑,无需对每个电池模组111设置单独的壳体结构,因此,能够使电池包100的多个电池模组111的结构更加紧凑,有利于提高电池包100的能量密度,降低电池包100的成本。
相关技术中,会将较长的连接件穿过多个电池模组的端板,以将多个电池模组固定连接在一起。这种方式对多个电池模组的定位要求较高,在对电池包的多个电池模组进行堆叠时,需要一次对电池包的多个电池模组进行精确定位,操作不方便,会对电池包的装配效率造成影响。
为了解决上述问题,在一些实施例中,如图2和图3所示,可以使电池包100包括第一连接件131和第二连接件132,端板1111和下方相邻的支撑件1211或支撑板140通过第一连接件131固定连接,支撑件1211和下方相邻的端板1111通过第二连接件132固定连接。
由此,能够支撑件1211可以通过第一连接件131和第二连接件132与上方和下方相邻的端板1111分别固定,在电池包100的多个电池模组111堆叠过程中,将两个支撑件1211一一对应支撑于第一个电池模组111的两个端板1111上后,可以通过第二连接件132将支撑件1211和下方相邻的第一个电池模组111的端板1111固定连接,然后,再将第二电池模组111堆放于第一个电池模组111上,并通过第一连接件131将支撑件1211和上方相邻的第二个电池模组111的端板1111固定连接。之后,可以采用同样的方式对第三、第四甚至更多个电池模组111进行堆叠。
与相关技术中使用长度较长的连接件穿过堆叠在一起的多个电池模组的端板相比,本申请实施例提供的电池包100在多个电池模组111堆叠过程中,支撑件1211支撑于电池模组111的端板1111后和电池模组111的端板1111支撑于支撑件1211后,可以通过第一连接件131和第二连接件132进行固定,只需使电池模组111的端板1111和对应的支撑件1211能够对准即可,对电池模组111的堆叠精度要求较低,有利于提高电池包100的装配效率。
需要说明的是,端板1111下方相邻的支撑件1211是指高度方向Z上相邻的两个电池模组111的端板1111中,支撑于支撑件1211上的端板1111;支撑件1211下方相邻的端板1111是指高度方向Z上相邻的两个电池模组111的端板1111中,设置为对支撑件1211进行支撑的端板1111。
另外,电池包100的高度方向Z是指电池包100正常使用或装配后顶部和底部的分布方向。电池包100的高度方向Z与第一方向X形成的夹角可以为直角或锐角,具体可根据电池包100的结构而定。
在一些实施例中,如图2和图3所示,在端板1111背离电芯的一侧凸设有连接部1112。端板1111的连接部1112支撑于下方相邻的支撑件1211或支撑板140,从而使端板1111支撑于下方相邻的支撑件1211或支撑板140。支撑件1211支撑于下方相邻的端板1111的连接部1112,从而使支撑件1211支撑于下方相邻的端板1111。也即,电池组件110的多个电池模组111沿第一方向X一侧的端板1111的连接部1112与同一侧的多个支撑件1211交替支撑于支撑板140的板面141。在高度方向Z上相邻的两个端板1111中,位于下方的端板1111的连接部1112通过支撑件1211支撑位于上方的端板1111的连接部1112。
通过使多个端板1111的连接部1112和同一侧的多个支撑件1211交替支撑于支撑板140的板面141,端板1111的主体部分受到上方电池模组111施加的压力较小,有利于降低端板1111主体的强度要求,进而降低端板1111的生产加工成本。
其中,可以使连接部1112沿第二方向Y延伸,高度方向Z、第一方向X及第二方向Y相互呈夹角。由此,能够增加连接部1112的长度,连接部1112的强度更高,使连接部1112更稳定对支撑件1211进行支撑,或者,使支撑件1211更加稳定的支撑于支撑件1211上。
具体地,可以使连接部1112沿第二方向Y延伸,且连接部1112沿第二方向Y的长度与端板1111沿第二方向Y的长度基本相同,从而尽可能提高连接部1112的结构强度。当然,也可以使连接部1112分为沿第二方向Y间隔设置的多段,且每段均沿第二方向Y延伸。
在一些实施例中,可以使端板1111的连接部1112至该端板1111顶部的距离大于连接部1112至该端板1111底部的距离。由此,能够使最下方的端板1111的连接部1112与支撑板140的板面141的距离更小,以便于使最下方的端板1111的连接部1112支撑于支撑板140的板面141上。
在其他实施例中,也可以使端板1111的连接部1112至该端板1111顶部的距离等于连接部1112至端板1112底部的距离;或者,使端板1111的连接部1112至该端板1111顶部的距离大于连接部1112至端板1112底部的距离,同样能够实现高度方向Z上相邻的两个端板1111中,位于下方的端板1111的连接部1112通过支撑件1211支撑位于上方的端板1111的连接部1112。
在一些实施例中,可以使第一连接件131沿高度方向Z穿过端板1111的连接部1112,并插入该端板1111的连接部1112下方相邻的支撑件1211,以将端板1111和下方相邻的支撑件1211固定连接,从而使支撑件1211和上方相邻的端板1111的固定连接更加方便。
具体地,如图3和图4所示,在支撑件1211开设有沿高度方向Z延伸的第一安装孔1213,在端板1111的连接部1112开设有沿高度方向Z贯穿的第二安装孔1113。当端板1111的连接部1112支撑于支撑件1211上后,可以使第一安装孔1213和第二安装孔1113对准,然后将第一连接件131从连接部1112上方穿过第二安装孔1113,并插入到第一安装孔1213内,从而使第一连接件131将端板1111的连接部1112与下方相邻的支撑件1211固定连接。
其中,可以使第一安装孔1213沿高度方向Z贯穿支撑件1211,可以使第一安装孔1213为从支撑件1211的顶部向下延伸的盲孔,只需使第一连接件131能够插入到第一安装孔1213,并与支撑件1211固定连接即可。
另外,第一连接件131可以包括第一锁紧件,该第一锁紧件可以为螺栓、螺钉、销钉等任何穿过支撑件1211上方相邻的端板1111的连接部1112,并插入支撑件1211后,能够将支撑件1211和上方相邻的端板1111固定连接的连接件。
同样地,可以使第二连接件132沿高度方向Z穿过支撑件1211,并插入支撑件1211下方相邻的端板1111的连接部1112,以将支撑件1211和下方相邻的端板1111固定连接,从而使支撑件1211和下方相邻端板1111的固定连接更加方便。
具体地,如图3至图5所示,在支撑件1211开设有沿高度方向Z贯穿的第三安装孔1215,在端板1111的连接部1112开设有沿高度方向Z延伸的第四安装孔1114。当支撑件1211支撑于端板1111的连接部1112上后,可以使第三安装孔1215和第四安装孔1114对准,然后将第二连接件132从支撑件1211上方穿过第三安装孔1215并插入第四安装孔1114内,从而使第二连接件132将支撑件1211和下方相邻的端板1111的连接部1112固定连接。
其中,可以使第四安装孔1114沿高度方向Z贯穿连接部1112,也可以使第四安装孔1114为从连接部1112的顶部向下延伸的盲孔,只需使第二连接件132能够插入到第四安装孔1114内,并与连接部1112固定连接即可。
另外,第二连接件132可以包括第二锁紧件,该第二锁紧件可以为螺栓、螺钉、销钉等任何穿过支撑件1211,并插入支撑件1211下方相邻的端板1111的连接部1112后,能够将支撑件1211和下方相邻的端板1111固定连接的连接件。
需要说明的是,本申请实施例中可以使第一连接件131和第二连接件132同时按照上述实施例对支撑件1211和端板1111的连接部1112进行固定,也可以仅使第一连接件131和第二连接件132中的按照上述实施例对支撑件1211和端板1111的连接部1112进行固定,而第一连接件131和第二连接件132中另一个或全部按照其他方式对支撑件1211和端板1111的连接部1112进行固定。例如:可以使第一连接件131和/或第二连接件132沿第一方向X穿过支撑件1211,并插入对应的端板1111,以将支撑件1211与对应的端板1111固定连接。
如图3至图5所示,支撑件1211包括第一支撑部1212,该第一支撑部1212夹持于高度方向Z上相邻的两个端板1111的连接部1112之间。从而使相邻两个电池模组111的端板1111中,位于下方的端板1111连接部1112通过第一支撑部1212支撑位于上方的端板1111的连接部1112。
在一些实施例中,可以使第一连接件131沿高度方向Z穿过端板1111的连接部1112,并插入该连接部1112下方相邻的支撑件1211,以将端板1111的连接部1112和下方相邻第一支撑部1212固定连接。可以理解的是,由于支撑件1211的第一支撑部1212夹持于高度方向Z上相邻的两个端板1111的连接部1112之间,因此,支撑件1211的第一支撑部1212与上方相邻端板1111的连接部1112的底部抵接,第一安装孔1213和第二安装孔1113是连贯的。当第一连接件131沿高度方向Z穿过端板1111的连接部1112,并插入端板1111下方相邻的支撑件1211的第一支撑部1212时,第一连接件131的长度可以设置的较短,且在穿过连接部1112的第二安装孔1113后,能够准确的插入到第一安装孔1213内。
在一些实施例中,如图3和图5所示,可以在第一支撑部1212的底面开设有避让空间1216,穿过第一支撑部1212下方相邻的连接部1112的第一连接件131的顶部容纳于避让空间1216内。由此,能够避免第一连接件131伸出于对应端板1111的连接部1112上方的部分与该连接部1112上方的支撑件1211相干涉。
具体地,支撑件1211的第一安装孔1213设于第一支撑部1212。第一安装孔1213沿高度方向Z贯穿第一支撑部1212。避让空间1216与第一安装孔1213的下端连通。避让空间1216的尺寸大于第一安装孔1213的内径,从而使避让空间1216又足够的空间设置为容纳第一连接件131伸出于对应端板1111的连接部1112上方的部分。
如图3至图5所示,支撑件1211包括第二支撑部1214,该第二支撑部1214位于高度方向Z上相邻的两个端板1111的连接部1112之间。在一些实施例中,可以使第二支撑部1214与支撑件1211上方相邻的端板1111的连接部1112间隔设置,第二连接件132沿高度方向Z穿过第二支撑部1214,并插入支撑件1211下方相邻的端板1111的连接部1112,以将第二支撑部1214与下方相邻的连接部1112固定连接。
可以理解的是,通过使第二支撑部1214与支撑件1211上方相邻的端板1111的连接部1112间隔设置,能够降低第二支撑部1214在高度方向Z上的高度,有利于缩短第二连接件132的长度。而且,还能够在第二支撑部1214与支撑件1211上方相邻的端板1111的连接部1112之间形成容纳空间,使第二连接件132伸出于第二支撑部1214上方的部分容纳于容纳空间内,而不会与支撑件1211上方相邻的端板1111的连接部1112发生干涉。
需要说明的是,本申请实施例中的支撑件1211的第一支撑部1212和第二支撑部1214可以同时按照上述实施例进行设置,也可以仅使支撑件1211的第一支撑部1212和第二支撑部1214中的一个按照上述实施例进行设置,而第一支撑部1212和第二支撑部1214中的另一个或全部按照其他方式进行设置。例如:使第一支撑部1212与下方或上方相邻的端板1111的连接部1112间隔设置,或者,使第二支撑部1214与上方相邻的端板1111的连接部1112抵接。
在一些实施例中,可以使支撑件1211沿第二方向Y延伸,其中,高度方向Z、第一方向X及第二方向Y相互呈夹角。由此,能够增加支撑件1211长度,使支撑件1211的强度更高,从而使支撑件1211能够更加稳定的对端板1111进行支撑。
其中,可以使与同一支撑件1211连接的第一连接件131数量为多个,并沿第二方向Y设置。由此,能够使支撑件1211通过多个第一连接件131与上方相邻的端板1111固定连接,有利于提高支撑件1211与上方相邻端板1111的连接稳定性。与同一支撑件1211连接的第一连接件131数量可以为2个、3个或更多个,此处不作限制。
另外,可以使与同一支撑件1211连接的第二连接件132数量为多个,并沿第二方向Y设置。由此,能够使支撑件1211通过多个第二连接件132与下方相邻的端板1111固定连接,有利于提高支撑件1211与下方端板1111的连接稳定性。与同一支撑件1211连接的第二连接件132数量为2个、3个或更多个,此处不作限制。
需要说明的是,可以使与同一支撑件1211连接的第一连接件131和第二连接件132的数量均为多个,也可以仅使第一连接件131和第二连接件132中的一者的数量为多个,当然,前者能够进一步提高多个电池模组111堆叠的稳定性。
在一些实施例中,可以使支撑件1211的第一支撑部1212和第二支撑部1214的数量分别为多个,并沿第二方向Y交替分布。其中,高度方向Z、第一方向X及第二方向Y相互呈夹角。由此,支撑件1211的多个第一支撑部1212能够分别通过第一连接件131与上方相邻的端板1111的连接部1112固定连接,且支撑件1211的多个第二支撑部1214能够分别通过第二连接件132与下方相邻的端板1111的连接部1112固定连接,从而进一步提高支撑件1211与上方相邻的端板1111和下方相邻的端板1111的连接稳定性。
其中,可以使支撑件1211的多个第一支撑部1212与连接于支撑件1211的多个第一连接件131一一对应连接,也可以使支撑件1211的一个第一支撑部1212与多个第一连接件131连接。同样地,可以使支撑件1211的多个第二支撑部1214与连接于支撑件1211的多个第二连接件132一一对应连接,也可以使支撑件1211的一个第二支撑部1214与多个第二连接件132连接。具体可根据支撑件1211和端板1111的结构而定,此处不再赘述。
在一些实施例中,可以使支撑板140的板面141还设有固定部142,位于最下方的电池模组111的端板1111通过第一连接件131与固定部142固定连接,从而将整个电池组件110和支撑组件120固定于支撑板140的板面141。
其中,端板1111背离电芯的一侧凸设有连接部1112。位于最下方的端板1111的连接部1112支撑于固定部142。第一连接件131沿高度方向Z穿过最下方的端板1111的连接部1112并插入固定部142,以将连接部1112和固定部142固定连接,从而使最下方的端板1111的连接部1112和下方的固定部142的固定连接更加方便。
具体地,支撑板140的固定部142数量为两个,两个固定部142沿第一方向X设置,以对最下方的电池模组111的两个端板1111的连接部1112进行支撑。固定部142沿第二方向Y延伸。在固定部142的顶部开设有沿高度方向Z延伸的第五安装孔143,当位于最下方的端板1111的连接部1112支撑于固定部142时,可以使固定部142的第五安装孔143与对应的连接部1112的第二安装孔1113对准,然后将第一连接件131从对应的连接部1112的上方穿过第二安装孔1113并插入第五安装孔143内,从而使最下方的端板1111的连接部1112与固定部142固定连接。
其中,第一连接件131可以为螺栓、螺钉、销钉等任何穿过最下方的端板1111的连接部1112,并插入固定部142后,能够将最下方的端板1111的连接部1112和支撑板140的固定部142固定连接的连接件。
在一些实施例中,如图1和图2所示,电池包100还包括外壳150,该外壳150罩设于支撑板140的板面141,从而使外壳150与支撑板140围合形成容纳电池组件110和支撑组件120的空间。
本申请实施例还提供一种车辆。如图6所示,车辆200包括电池包100,该电池包100的具体结构参照上述各实施例,由于本车辆200采用了上述所有实施例的全部技术方案,因此至少具有上述实施例的技术方案所带来的所有有益效果,在此不再一一赘述。
