技术领域
本申请涉及储能产品技术领域，具体涉及一种电池包。
 背景技术
为提高电池包的电容量，通常在电池包内布置多个电芯模组，多个电芯模组可分层布置，以合理利用电池包内部空间。对于多层电芯模组，通常采用支架将模组隔开，且针对每层电芯模组均在底部设置一层冷板，但这种布置方式会增加电池包在厚度方向上的尺寸，电池包空间利用率低。
相关技术公开一种双层模组的集成化电池总成，多个电芯模组呈上下两层分布，两层电芯模组之间设置有水冷板总成，通过该水冷板总成为上下两层电芯模组进行冷却降温，能缩减电池包的厚度，提高电池包的空间利用率。
 发明概述
但上述方案存在以下缺陷：水冷板总成内部的一个流道同时为上下两层电芯模组降温，冷却降温效果较差，电芯模组长时间运行后很可能由于冷却速度慢而引发热失控，缩短电池包的使用寿命。
因此，亟需一种新的电池包，以解决现有技术中存在的上述问题。

本实施例提供一种电池包，如图1和图2所示，为该电池包的分解视图。该电池包在缩减电池包厚度方向尺寸，提高电池包空间利用率的同时，能够提高多层电芯模组1的冷却降温效果，防止电芯模组1由于冷却较慢而发生热失控等危险，延长电池包的使用寿命。
该电池包包括至少两层电芯模组1，例如两层、三层、四层以及更多层数的电芯模组1。每层电芯模组1包括一个或者多个电芯模组1，具体到图1和图2中，每层电芯模组1包括2×2矩阵分布的四个电芯模组1，每个电芯模组1均包括多个电芯11。其他实施例中，每层电芯模组1的分布可根据设计要求选定，不仅限于2×2矩阵分布的形式，比如为2×3、3×3矩阵分布。
每相邻两层电芯模组1之间均设置有液冷组件2。通过该液冷组件2同时为相邻的两层电芯模组1散热降温，无需在相邻模组之间设置设置为支撑电芯模组1的支架，能缩减电池包厚度方向尺寸，提高电池包空间利用率。
参见图3、图4以及图5，液冷组件2包括依次叠设的第一板21、第二板22和第三板23，第二板22位于第一板21和第三板23之间，且第一板21、第二板22以及第三板23连接为一体。第一板21和第二板22之间形成第一冷却流道24，第二板22和第三板23之间形成第二冷却流道25。第一冷却流道24和第二冷却流道25内设置为通入不断循环流动的冷却液，实现冷却降温。
在两层电芯模组1之间的液冷组件2中，其第一板21和第二板22之间限定出第一冷却流道24，第二板22和第三板23之间限定出第二冷却流道25，第一冷却流道24和第二冷却流道25分别针对性地为相邻的两层电芯模组1降温散热，相比于通过一个冷却流道同时为相邻两层电芯模组1冷却降温的方式，能有效提高多层电芯模组1的冷却降温效果，使电芯模组1中的电芯11能在适宜温度环境下工作，防止电芯模组1由于冷却较慢而发生热失控等危险，延长电池包的使用寿命。
示例性地，第一板21和第二板22之间、以及第二板22和第三板23之间均为焊接连接，可提高连接稳固性和密封性。
一些实施例中，第一冷却流道24和第二冷却流道25之间连通，冷却液的进液口固定设置于第一板21上，以与第一冷却流道24直接连通，或者，冷却液的进液口固定设置在第三板23上，以与第二冷却流道25直接连通。第一冷却流道24和第二冷却流道25之间设置有连通口，该连通口设置于第二板22上。通过该进液口输入的冷却液，能流经第一冷却流道24和第二冷却流道25，在实现为相邻两层电芯模组1降温的同时，能节省部件数量，减少占用空间，降低成本。
另一些实施例中，第一冷却流道24和第二冷却流道25之间也可以不连通。此时需要单独在第一板21和第三板23上均设置一个设置为引入冷却液的进液口和设置为引出冷却液的出液口，第一冷却流道24和第二冷却流道25相互独立，内部冷却液不相通。
在一些实施例中，第一板21背向第二板22的一侧面为平面，该平面设置为与一层电芯模组1接触；第三板23背向第二板22的一侧面也为平面，该平面设置为与另一层电芯模组1接触。将液冷组件2与电芯模组1接触的一面设置为平面，能够提高电池包内部电芯模组1与液冷组件2之间的相对稳定性，同时使液冷组件2与电芯模组1之间具有足够的接触面积，提高散热效果。
具体到本实施例中的图5和图6，第一板21和第三板23均为平板，结合图7和图8，第二板22的两侧分别设置有第一流道槽221和第二流道槽222。第一流道槽221的内壁和第一板21围设形成第一冷却流道24，第二流道槽222和第三板23之间围设形成第二冷却流道25。由于第一板21和第三板23均为平板，因此其两侧面均为平面，易于与电芯模组1接触，而且，该液冷组件2中仅需要在一个第二板22上分别设置第一流道槽221和第二流道槽222，其余的两个板（第一板21和第三板23）均设置为平面，即可限定出第一冷却流道24和第二冷却流道25，简化加工工序，提高加工效率。
参见图7和图8，第二板22的两侧分别凸设有第一凸包223和第二凸包224，第一凸包223和第二流道槽222设于第二板22的同一侧面，第二凸包224和第一流道槽221设于第二板22的同一侧面。第一凸包223背向第二流道槽222的一侧围设形成的第一流道槽221，第二凸包224背向第一流道槽221的一侧围设形成的第二流道槽222。即，第二板22上凸设形成第一凸包223的同时，在第一凸包223的背面形成凹槽，该凹槽即为第一流道槽221。第二板22上凸设形成第二凸包224的同时，在第二凸包224的背面形成凹槽，该凹槽即为第二流道槽222。具体地，本实施例中的第二板22一体冲压成型，冲压模具与第一流道槽221和第二流道槽222的形状和尺寸相适配，可通过一次冲压成型出的第一流道槽221、第二流道槽222、第一凸包223以及第二凸包224，工序简便。
可以理解，第一凸包223和第一流道槽221的形状一致，第二凸包224和第二流道槽222的形状一致。第二凸包224成型时，其背面即可形成第二流道槽222，第一凸包223成型时，其背面即可形成第一流道槽221。
本实施例中，第一冷却流道24和第二冷却流道25中的至少一者为蛇形流道，能提高冷却液在其内的流动时间，使得冷却液与电芯模组1充分接触，提高冷却效果。
具体到图7和图8，第一流道槽221呈蛇形延伸，相应地，第一凸包223也呈蛇形延伸。第二凸包224围设在第一流道槽221外部，第二流道槽222围设在第一凸包223外部。
结合图4、图5以及图6，第一凸包223与第三板23密封接触，第二凸包224与第一板21密封接触，使第一冷却流道24和第二冷却流道25内的冷却液以限定的路径流动。
在另一可选的实施例中，可在第一板21和第三板23上设置流道。具体地，第一板21面向电芯模组1的一面为平面，第一板21面向第二板22的一侧设置有第三流道槽，第三流道槽的内壁和第二板22之间围设形成第一冷却流道24。第三板23面向电芯模组1的一面为平面，第三板23面向第二板22的一侧设置有第四流道槽，第四流道槽的内壁和第二板22之间围设形成第二冷却流道25。在一些实施例中，第二板22此时可以为平板，该平板的两侧面分别与第一板21和第三板23限定出第一冷却流道24和第二冷却流道25。或者，第二板22也可以为流道板，其两侧分别设置有第五流道槽和第六流道槽，第一板21上的第三流道槽的内壁和第二板22上的第五流道槽的内壁共同围设出第一冷却流道24，第三板23上的第四流道槽和第二板22上的第六流道槽共同围设出第二冷却流道25。
参见图9和图10，电芯11包括外壳111和极柱112，极柱112设于外壳111上。本实施例中，电芯模组1设置有两层，且两层电芯模组1中相对液冷组件2镜像对称设置，极柱112位于外壳111背向液冷组件2的一侧。因此，外壳111未设置极柱112的一侧直接与液冷组件2之间平面接触，提高接触面积，散热效果更好，有利于保持多个电芯11的温度一致性。
示例性地，两层电芯模组1上下分布，上层电芯模组1的摆放方式为极柱112朝上，下层电芯模组1的摆放方式为极柱112朝下，如此，使得上层电芯模组1中电芯11的外壳111与第一板21之间平面接触，下层电芯模组1中电芯11的外壳111与第三板23之间平面接触。
在一些实施例中，第一板21和上层的电芯模组1之间设置有第一导热结构胶3，具体地，第一板21与上层的电芯11的外壳111之间通过第一导热结构胶3粘接固定。第二板22和电芯模组1之间设置有第二导热结构胶4，具体地，第三板23与下层的电芯11的外壳111之间通过第二导热结构胶4粘接。一方面，通过第一导热结构胶3和第二导热结构胶4能快速实现液冷组件2与上下两层电芯模组1之间的固定，且固定牢固度高；另一方面，第一导热结构胶3和第二导热结构胶4具备良好的导热性能，能提高液冷组件2与上下两层电芯模组1之间的换热效率，提高冷却降温效果。
示例性地，第一导热结构胶3和第二导热结构胶4均为双组份聚胺酯导热结构胶，其强度较高，粘接牢固度高，导热性能优良。
参见图1、图2、图9以及图10，电池包还包括壳架组件5，壳架组件5包括主壳体51和分隔梁52。主壳体51具有空腔，液冷组件2连接于主壳体51的内壁，具体地，液冷组件2可以通过焊接或者铆接或者螺栓连接的方式和主壳体51固定连接。液冷组件2将空腔分隔为上下两个容纳腔室，每个容纳腔室内放置一层电芯模组1。即，上下两层电芯模组1对应置于上下两个容纳腔室内。在一些实施例中，每个容纳腔室内均设置有一个或多个分隔梁52，分隔梁52将容纳腔室分隔为多个模组腔室510，单层电芯模组1包括多个电芯模组1，该多个电芯模组1一一对应地放置于多个模组腔室510内。分隔梁52的设置能将电芯模组1之间分隔开，防止两个电芯模组1之间短路，以及，在其中一个电芯模组1热失控时，能起到较好的隔离作用，防止蔓延至其他电芯模组1内。另外，分隔梁52能够限定电芯模组1的位置，确保电芯11在电池包中的稳定性和安全性。
本实施例中，分隔梁52为电池领域中的膨胀梁。膨胀梁与主壳体51之间通过焊接或者铆接或者螺栓连接的方式进行固定。
示例性地，参见图9和图10，容纳腔室内均设置有四个分隔梁52，四个分隔梁52呈王字型设置，以分隔成四个模组腔室510。每层电芯模组1包括四个电芯模组1，该四个电芯模组1一一对应地放置于四个模组腔室510内。
相应地，上层设置四个第一导热结构胶3，上层的每个电芯模组1通过一个第一导热结构胶3粘接在对应的模组腔室510内；下层设置四个第二导热结构胶4，下层的每个电芯模组1通过一个第二导热结构胶4粘接在对应的模组腔室510内。
参见图1和图2，壳架组件5还包括两个盖体53，两个盖体53分别可拆卸地扣合于两个容纳腔室的腔口。当两层电池模组上下分布时，两个盖体53分别为上盖和底板。
继续参见图1和图2，电池包还包括压条6，压条6能将电芯11压紧固定在模组腔室510内。具体地，压条6的两端与主壳体51连接，且压条6压紧于电芯11的外壳111背向模组腔室510底壁的一侧。电芯模组1放置于模组腔室510内部后，将压条6的两端与主壳体51连接，从而将电芯模组1压紧在模组腔室510内，避免电芯模组1在主壳体内发生窜动。压条6高于外壳111上设置的极柱112，盖体53在扣合到主壳体51上后压紧于压条6上，而不会压到极柱112上，能提高压条6的稳固性，进而提高电芯11在电池包内的稳固性和安全性。
在一些实施例中，压条6的两端与主壳体51之间为焊接或者铆接或者螺纹连接等，只要能实现压条6与主壳体51之间的稳固连接即可。
在一些实施例中，压条6的两端可以连接在主壳体51内设置的分隔梁52上，或者，压条6的两端也可以连接在主壳体51的内壁上。
参见图11，电芯11的外壳的两端均通过压条6压紧固定，使电芯11受力均衡，确保电芯11在电池包内的稳固性和安全性。
在一些实施例中，盖体53与主壳体51之间可以使用螺钉或者螺栓等紧固件螺纹连接，确保盖体53与主壳体51之间稳固连接不松脱，而且，当电池包内部发生故障时，方便拆卸盖体53进行检修。
在一些实施例中，参见图11，压条6上设置有减料腔61，在保证强度和刚度的同时能减少材料用量，降低成本。
示例性地，每个电芯模组1包括两列电芯11，参见图11，对应该两列电芯11设置有三个压条6，包括两个侧压条和一个中间压条，两列电芯11远离彼此的肩部各自设置一个侧压条，中间压条同时压紧在两列电芯11靠近彼此的肩部上。侧压条设置一个减料腔61，中间压条的宽度大于侧压条的宽度，其设置两个减料腔61，两个减料腔61之间通过隔条隔开。
在一些实施例中，压条6与外壳111之间夹设有第一胶层7；压条6与盖体53之间夹设有第二胶层8。通过第一胶层7和第二胶层8实现压条6与盖体53和电芯11外壳111之间的粘接，组装效率较快，能提高电池包的生产速度。
第一胶层7和第二胶层8示例性为聚氨酯结构胶。
示例性地，压条6可以为绝缘材质制成，例如塑料等，具备较好的绝缘作用。或者，压条6可以包括金属条以及设置于金属条两侧的绝缘膜，在具备较高强度的同时能起到绝缘作用。
本实施例中，盖体53、压条6、电芯模组1、液冷组件2之间依次粘接链接，使电池包形成一个整体，组装效率高，整包刚度较高。而且，由于取消了设置为支撑电芯模组1的支架，通过一个液冷组件2同时为上下两层电芯模组1降温，简化了整包结构，提升了整包的空间利用率，可增加整包电量，提升续航里程。
