下面结合附图具体描述根据本申请实施例的电池模组100。
如图1至图6所示，根据本申请实施例的电池模组100包括内壳20和电池模块30。
具体而言，内壳20内限定有收容空间12，内壳20上设有变形缓冲部11，变形缓冲部11能够收缩变形，以收缩收容空间12。电池模块30设在收容空间12内，在变形缓冲部11处于收缩变形的情况下，收容空间12收缩，内壳20与电池模块30相抵。
换言之，根据本申请实施例的电池模组100主要由内壳20和电池模块30组成。本申请的电池模组100可以是长软包模组，在该电池模组100中，如图1至图3所示，内壳20内形成有用于装入电池模块30的收容空间12。如图2、图4、图5和图6所示，内壳20上设置有变形缓冲部11，变形缓冲部11受力后能够收缩变形，达到收缩收容空间12的目的。电池模块30安装在收容空间12内，在变形缓冲部11处于收缩变形的情况下，收容空间12收缩，内壳20的相对两侧能够与电池模块30相抵，压紧电池模块30，从而保证电池模块30在内壳20内的预紧力提升电池的循环寿命。
由此，根据本申请实施例的电池模组100，通过在内壳20上设置能够收缩变形的变形缓冲部11，内壳20内设置收容空间12，电池模块30装入收容空间12后，可以通过对内壳20施加作用力，使内壳20上的变形缓冲部11收缩变形，收缩收容空间12，保证内壳20的相对两侧能够压紧电池模块30，对电池模块30提供一定的预紧力，有效提升电池的循环寿命。
根据本申请的一个实施例，内壳20内限定有多个收容腔121，每个收容腔121沿内壳20的第一方向延伸，且多个收容腔121在内壳20的第二方向上间隔开布置，多个收容腔121构成收容空间12，每个收容腔121内设有一个电池模块30，内壳20上对应每个收容腔121的在第三方向上的相对两侧的至少一侧上设有沿第一方向延伸的变形缓冲部11。
也就是说，参见图2和图4，内壳20内可以形成有多个收容腔121，每个收容腔121可以沿着内壳20的第一方向延伸，并且多个收容腔121在内壳20的第二方向上可以间隔开布置。在本申请中，如图1所示，内壳20可以设置成方形壳，内壳20的第一方向可以理解为内壳20的长度方向(参见图1中箭头方向)，内壳20的第二方向可以理解为内壳20的宽度方向(参见图1中箭头方向)，内壳20的第三方向可以理解为内壳20的高度方向(参见图1中箭头方向)。
多个收容腔121可以共同构成收容空间12，通过在内壳20内设置多个收容腔121，也能够提高内壳20的结构强度。每个收容腔121内可以用于装入一个电池模块30，每 个电池模块30可以由多个电芯组310串联形成，每个电芯组310包括至少一个电芯311，当电芯组310包含两个以上的电芯311时，电芯311之间可以是并联连接。每个电池模块30可以从每个收容腔121的一端装入内壳20中，每个电池模块30与收容腔121之间留有一定的安装间隙，保证电池模块30能够顺利地塞入收容腔121中。内壳20上对应每个收容腔121的在第三方向(高度方向)上的相对两侧的至少一侧上设置有沿内壳20的长度方向延伸的变形缓冲部11。变形缓冲部11可以设置在内壳20高度方向上的一侧，也可以在内壳20高度方向上的两侧均设置变形缓冲部11。当在内壳20的宽度方向的相对两侧施加作用力时，内壳20上的变形缓冲部11会向内壳20的宽度方向收缩，从而使内壳20能够压紧每个电池模块30，保证电池的循环寿命。
根据本申请的一个实施例，内壳20内限定有多个凹槽，每个凹槽内所限定的空间为一个收容腔121，每个凹槽的开口朝向内壳20的同一侧，内壳20的与每个开口相对的一侧上分别设有变形缓冲部11。
换句话说，内壳20内形成有多个凹槽，每个凹槽内所限定的空间可以立理解为一个收容腔121，每个凹槽的开口朝向内壳20的同一侧敞开，内壳20的与每个开口相对的一侧上(每个凹槽的槽底)分别设置有变形缓冲部11。通过在内壳20上设置多个开口方向一致的凹槽结构，电池模组100可以直接从每个凹槽的开口处放入内壳20中，同时通过对内壳20的宽度方向(第二方向)的相对两侧施加作用力，使变形缓冲部11收缩变形，给电池模块30提供一侧预紧力。
根据本申请的一个实施例，内壳20内限定有多个凹槽，每个凹槽内限定的空间为收容腔121，相邻两个凹槽的开口的方向相反，且内壳20的与每个开口相对的一侧上分别设有变形缓冲部11。
也就是说，如图4至图6所示，内壳20内可以形成有多个凹槽，每个凹槽内限定的空间可以为收容腔121。相邻两个凹槽的开口的方向相反，将内壳20构造成长城形结构，电池模组100形成一个U形串联结构。内壳20的与每个开口相对的一侧上分别设有变形缓冲部11。上层串联电池所形成的电池模块30可以从内壳20上方开口处装入，下层串联电池所形成的的电池模块30可以从内壳20下方开口处装入。待每个电池模块30分别装入收容腔121后，对内壳20的宽度方向(第二方向)的相对两侧施加作用力，使变形缓冲部11收缩变形，给电池模块30提供一侧预紧力，提升电池模组100的循环寿命。
根据本申请的一个实施例，变形缓冲部11为朝向收容空间12凹陷的凹形体，在内壳20在第二方向上受挤压的情况下，凹形体在第二方向上收缩。
换句话说，参见图5和图6，每个变形缓冲部11可以分别设置成朝向对应的收容 腔121凹陷的凹形体。当内壳20在宽度方向上受挤压时，凹形体可以在内壳20的宽度方向上收缩变形，从而使每个收容腔121收缩，保证每个凹槽的两个侧壁能够把电池模块30夹紧，从而提高电池的循环寿命。在本申请中，内壳20与变形缓冲部11一体成型，降低内壳20的成型难度和成型成本。
在本申请的一些具体实施方式中，内壳20还包括：压板13，压板13设在内壳20在第二方向上的相对两侧。
也就是说，如图1、图2、图4和图5所示，内壳20还可以包括压板13，压板13可以设置在内壳20在宽度方向上的最外层相对两侧上。
通过设置压板13可以提高内壳20的结构强度，便于对内壳20施加作用力，确保每个内壳20内的收容腔121能够收缩变形。
电池模组100还包括：上拉板31和下拉板32，上拉板31和下拉板32分别设在内壳20在第三方向上的相对两侧。上拉板31与内壳20粘接、焊接或铆接连接，下拉板32与内壳20粘接、焊接或铆接连接。
参见图2，电池模组100还可以包括上拉板31和下拉板32，上拉板31设置在内壳20上方，构成内壳20的顶板。下拉板32设置在内壳20下方，构成内壳20的底板。上拉板31与内壳20之间通过粘接、焊接或铆接等方式连接，下拉板32与内壳20之间可以通过粘接、焊接或铆接等方式连接。粘接、焊接或铆接等连接方式，易于操作和固定，有利于提升电池模组100的装配效率。
在本申请中，如图1和图2所示，以长城形结构的壳体10壳20(相邻两个凹槽的开口的方向相反)为例，电池模组100可以通过上拉板31、内壳20(长城形)、下拉板32、上层串联电池(上层的电池模块30)、下层串联电池(下层的电池模块30)组成。内壳20由两侧的压板13和中间的长城形(相邻两个凹槽的开口的方向相反)组成，内壳20上设置有变形缓冲部11，上层串联电池从长城形的内壳20上部装入，下层串联电池从长城形的内壳20的下部装入，长城形的内壳20与上层串联电池、长城形内壳20与下层串联电池间可以设置有胶水层，上拉板31与上串联电池、下拉板32与下串联电池间也可以设置有胶水。在电池模组100装配的过程中，先将串联好的电池模块30放入长城形的内壳20。然后，对内壳20的宽度方向的两侧压紧，使变形缓冲部11收缩，将电池模块30压紧。最后，安装上拉板31和下拉板32，上拉板31、下拉板32分别与长城形的内壳20间通过胶粘、焊接或者铆接等方式连接为一体，有效提升电池的循环寿命。
总而言之，根据本申请实施例的电池模组100，通过在内壳20上设置能够收缩变形的变形缓冲部11，内壳20内设置收容空间12，电池模块30装入收容空间12后，可 以通过对内壳20施加作用力，使内壳20上的变形缓冲部11收缩变形，收缩收容空间12，保证内壳20的相对两侧能够压紧电池模块30，对电池模块30提供一定的预紧力，有效提升电池的循环寿命。
根据本申请的第二方面，提供一种电池包，包括上述实施例中的电池模组100。由于根据本申请实施例的电池模组100具有上述技术效果，因此，根据本申请实施例的电池包也应具有相应的技术效果，即本申请的电池包通过采用该电池模组100，能够对电池包内电池提供预紧力，有效提升电池的循环寿命。
根据本申请的第三方面，提供一种电池包。
下面参考图7-图15描述根据本申请实施例的电池包1，包括：外托盘10、内壳20和多个电池模块30。
具体来说，内壳20设置于外托盘10内，内壳20弯折设置且形成有多个交错设置的第一凹槽210和第二凹槽220，第一凹槽210和第二凹槽220的开口朝向相反，内壳20上还设置有内壳定位部230；第一凹槽210和第二凹槽220内设置有电池模块30，电池模块30包括设置于其端部的端部间隔件330，端部间隔件330设置于电池模块30的端部，端部间隔件330设置有电池定位部350，电池定位部350与内壳定位部230定位配合。
不仅如此，电池模块30还包括：多个串联的电芯组310、中部间隔件320和保护膜340。中部间隔件320设置于相邻的多个电芯组310之间且与多个电芯组310设置于保护膜340内。电芯组310包括多个电芯311，多个电芯311可以并联连接。
可以理解的是，在电池包1的构建过程中，外托盘10适用于承载内壳20和电池模块30，不仅为电池模块30和内壳20的组装提供位置，以便于电池包1的构建，而且还能为装设在其内的内壳20和电池模块30提供保护作用。
而在内壳20的构建过程中，内壳20弯折设置并在其上形成更多个交错设置的第一凹槽210和第二凹槽220，第一凹槽210和第二凹槽220相邻设置，从而让相邻的电池模块30适于通过内壳20隔开，以避免电池模块30出现热失控的情况后对其相邻的电池模块30造成影响，以提升电池包1的使用安全性。
同时，电池模块30适于由多个电芯组310构成，每个电芯组310适于由多个电芯311构成，多个电芯组310之间设有中部间隔件320，中部间隔件320与电芯311连接且可以将多个电芯组310间隔设置。这样一来，通过多个电芯组310之间设有中部间隔件320，中部间隔件320能够支撑并保护相邻电芯311极耳，从而起到对相邻电芯311极耳的保护作用。同时，中部间隔件320适于与多个电芯311进行连接组装，以便于多个电芯组310的连接组装，提升组装效率。此外，在电芯311的端部还设有端部间隔件 330，端部间隔件330适于限制在电池模块30的两端，以提升电池模块30的结构稳定性。而保护膜340设于电池模块30的外侧，以适于保护电池模块30，提升电池包1的使用寿命。
不仅如此，在端部间隔件330上还设有电池定位部350，电池定位部350适于与内壳20上的内壳定位部230进行定位配合，使得电池模块30在组装完毕后，电池定位部350适于与内壳定位部230进行配合,以使电池模块30组装到内壳20的过程得到简化，从而提升电池包1的组装效率。同时，电池模块30在组装到内壳20上之后，电池定位部350与内壳定位部230进行配合，以使电池模块30在内壳20上的组装更为可靠，从而让电池包1的结构更为稳定，以提升电池包1的使用性能。
根据本申请实施例的电池包1，通过设有电池定位部350和内壳定位部230，并使其进行定位配合，不仅可以简化电池包1的组装过程，提升组装效率，而且让电池模块30与内壳20之间的连接装配更为稳定，以使电池包1的使用性能得到提升。
在一些实施例中，如图13所示，端部间隔件330包括设置于电池模块30两端部的第一端部间隔件331和第二端部间隔件332，第一端部间隔件331设置有第一电池定位部351且第二端部间隔件332设置有第二电池定位部352，内壳定位部230包括第一内壳定位部240和第二内壳定位部250，第一凹槽210的两端分别设有第一内壳定位部240和第二内壳定位部250，第二凹槽220的两端分别设有第一内壳定位部240和第二内壳定位部250，第一内壳定位部240与第一电池定位部351定位配合且第二内壳定位部250与第二电池定位部352定位配合。
这样，通过在电池模块30的两端分别设有第一端部间隔件331和第二端部间隔件332，由于第一端部间隔件331上所设有的第一电池定位部351适于与内壳20上所设有的第一内壳定位部240进行定位配合，以及第二端部间隔件332上所设有的第二电池定位部352适于与内壳20上所设有的第二内壳定位部250进行定位配合，使得电池模块30在内壳20上的连接组装更为可靠。
在一些具体的实施例中，第一电池定位部351设置于第一端部间隔件331的至少一侧且构造为限位凸块，第一内壳定位部240构造为限位孔，限位凸块配合在限位孔内。

可以理解的是，通过将第一电池定位部351构造成限位凸块，由于限位凸块具有更为稳定的结构，使得限位凸块在装设到限位孔内之后，电池模块30与内壳20之间具有更好的限位效果，以使电池模块30在内壳20上的组装更为牢靠。
在一些具体的实施例中，限位凸块设置于第一端部间隔件331的一侧，第一凹槽210的槽壁和第二凹槽220的槽壁均设置有对应两个限位孔，限位凸块与限位孔定位配合。需要说明的是，限位凸块适于形成在第一端部间隔件331的一侧，在电池模块30进行在组装到第一凹槽210与第二凹槽220时，限位凸块置于限位孔内并定位配合。第一凹槽210上的的限位孔与第二凹槽220上的限位孔靠近设置，如图10所示。第一凹槽210上的限位孔与第二凹槽220上的限位孔可以设置于第一凹槽210和第二凹槽220的共同的槽壁上。第一凹槽210和第二凹槽220相邻设置，因此第一凹槽210与第二凹槽220具有共同的槽壁，即第一凹槽210的一槽壁同时也是第二槽层220的槽壁。限位孔的一部分设置于第一凹槽210和第二凹槽220的共同的槽壁上。
这样，通过将限位凸块设置在第一端部间隔件331的一侧，使得电池模块30在与第一凹槽210或者第二凹槽220进行装配的时候，限位凸块适于与限位孔进行配合，从而起到电池模块30在组装过程中的防呆作用，以便于电池模块30与内壳20之间的连接组装，且能够让电池模块1与内壳20之间的组装效率得到提升。

在一些具体的实施例中，第二电池定位部352设置于第二端部间隔件332的至少一侧且构造为弹性卡扣，第二内壳定位部250构造为卡孔，弹性卡扣卡接在卡孔内。这样，采用弹性卡扣的形式，弹性卡扣在装设过程中适于进行弹性变形，以便于第二电池定位部352与第二内壳定位部250之间的连接组装，提升组装效率。
在一些实施例中，如图15所示，第二端部间隔件332的两侧均设置有弹性卡扣且第二端部间隔件332的每侧至少有两个上下间隔设置的弹性卡扣，第一凹槽210和第二凹槽220的槽壁均设置有卡孔，弹性卡扣与卡孔卡合连接。
需要说明的是，第二端部间隔件332上设有弹性卡扣，在相邻电池模块30在内壳20上进行组装时，可以将相邻电池模块30上第二端部间隔件332交错设置，以使相邻 电池模块30上的弹性卡扣交错连接在内壳20上的卡孔中，从而让相邻电池模块30能够稳定可靠的连接在内壳20上，使得电池模块30与内壳20之间的连接更为可靠。
在一些实施例中，如图13所示，第二端部间隔件332包括：多个第二内连接件3321和外保护盖3322，多个第二内连接件3321设置于外保护盖3322内且分别与多个电芯组310的端部相连接，外保护盖3322上设置有弹性卡扣。需要说明的是，第二内连接件3321与采样镍片连接，且第二内连接件3321与电芯311进行连接。

在一些实施例中，如图8所示，第一凹槽210的开口向上且第一凹槽210的底板和外托盘10的底部之间设置有第一胶层410，第一凹槽210内的电池模块30底部设置有第一缓冲垫360且第一凹槽210内的电池模块30顶部设置有第二胶层420；和/或第二凹槽220的开口向下且第二凹槽220的顶板外侧设置有第三胶层430，第二凹槽220内的电池模块30顶部与第二凹槽220顶板之间设置有第二缓冲垫370且第二凹槽220内的电池模块30底部设置有第四胶层440。
