具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考图1-图13描述本发明实施例的电池模组组件100、电池包1000及车辆。
本发明实施例的电池模组组件100包括电池模组1、巴片2和第一液冷板3。
电池模组1包括多个沿第一方向(例如，图1中所示的左右方向)排布的电芯11，巴片2具有多个，每个巴片2连接于两个相邻电芯11的极柱111上以形成巴片排；第一液冷板3沿第一方向延伸，且第一液冷板3沿垂直于第一方向的第二方向(例如，图1中所示的上下方向)附接于巴片排上。
本发明实施例的电池模组组件100，通过连接在极柱111上的巴片2上设置第一液冷板3，可以直接将极柱111上产生的热量通过第一液冷板3及时快速的散出，进而提升了液冷组件对电池模组1的整体冷却能力，防止热量在极柱111处蓄积造成电芯温度过高，限制充电电流，适用于快充电池，进而有利于提升电池模组1的快充能力和使用安全性。
因此，本发明实施例的电池模组组件100具有提升极柱111处散热能力及快充能力的优点。
具体地，巴片2可以将电池模组1中相邻两个电芯11串联和/或并联。极柱111设置在电芯11的顶部，巴片2连接在极柱111上，第一液冷板3设置在巴片2的上表面。
如图7至图8所示，第一液冷板3包括相连的液冷部31和搭接边32，液冷部31附接于巴片排上，搭接边32贴设于电芯11的肩部112上。
本发明实施例的电池模组组件100，通过将第一液冷板3分为相连的液冷部31和搭接边32，液冷部31附接于巴片排上，搭接边32贴设于电芯11的肩部112上，并将搭接边32不仅可以对电芯11的肩部112进行散热，还可以通过液冷部31对电芯11的肩部112上的热量散出，不仅有助于降低甚至是消除电芯11肩部112和极柱111处的温差(搭接边32具有匀热的作用)，还降低了电池模组1的整体冷却能力。由此，该电池模组组件100进一步提升了对电池模组1的散热能力。
具体地，电池模组1包括沿第二方向排列的多个电芯11，每个电芯11均具有肩部112。当电芯11的正极柱和负极柱均设置在电芯11的顶面时，且正极柱和负极柱靠近电芯11中部设置，肩部112可以形成在电芯11的沿第三方向(例如，图1中所示的前后方向)的两侧，如图11所示。在正极柱和负极柱靠近电芯11边沿设置，肩部112形成在电芯11防爆阀和正极柱，以及电芯11防爆阀和负极柱之间。当电芯11的正极柱和负极柱相对设置在电芯11的顶部和底部。例如正极柱设置在电芯11的顶面的中部区域，肩部112可以形成在电芯11的正极柱沿第三方向的两侧上，例如，刀片电芯11。
巴片2可以焊接、螺接、铆接或导电胶粘接于电池模组1的极柱111上。由此，本发明实施例的电池模组组件100具有连接便捷性高的优点。例如，连接电芯和电芯之间巴片2可以通过铆接或激光焊接等工艺与电芯11的极柱111连接，从而实现整个电池模组1的高压串联或并联。
可选地，巴片2可以采用铜合金巴片2或铝合金巴片2，巴片2上设有观察孔。进一步地，该巴片2可以采用冲压、机加工或铸造等工艺成型。
可选地，巴片2与第一液冷板3通过导热结构胶、导热垫、导热凝胶、导热硅脂、结构胶等各类导热介质连接。
可选地，极柱可以是方形和圆形。极柱一般包括正极柱和负极柱，正极柱和负极柱可以设置在电池模组1的同一侧，也可以相对设置。
在垂直于第一方向和第二方向的第三方向(例如，图1中所示的前后方向，图6所示的第三方向)上，极柱111的长度L1与电池模组1的长度L3之间的比值为0.1-0.4。由此，既避免了该比值过大(超出0.40)，电芯11的顶面没有足够的面积容纳电芯11的正极柱和负极柱之间必要的电气安全距离，存在安全性差的问题；又避免比值过小，会导致电芯11的顶面与第一液冷板3贴合的面积占比小，进而导致电芯11的顶部在热交换效率差的问题。因此，该电池模组组件100兼具冷却效果好和结构强度高的优点。
具体地，电芯11的正极柱和负极柱均设置在电芯11的同一侧，也可以是2个或多个正极柱+2个或多个负极柱。
在第一方向上，如图14所示，极柱111的宽度L2与电池模组1的宽度L4之间的比值为0.1-0.99。由此，既避免了极柱111的宽度L2与电池模组1的宽度L4之间的比值过小，造成冷却效果差的问题，还避免了极柱111的宽度L2与电池模组1的宽度L4之间的比值过大，第一液冷板3存在安装干涉的问题。因此，该电池模组组件100兼具冷却效果好和安装便捷性高的优点。
在垂直于第一方向和第二方向的第三方向上，巴片2的长度与极柱111的长度L1的比值为0.1-5。由此，既避免了巴片2的长度与极柱111的长度L1的比值过大，巴片2存在安装干涉的问题；又避免比值过小，会导致巴片2与极柱111贴合面占比小，进而导致电芯11的电连接或热交换效率差的问题。因此，该电池模组组件100兼具冷却效果好和安装便捷性高的优点。
巴片2的长度与极柱111的长度L1的比值为1.5-5。也就是说，巴片2的长度大于极柱111的长度。进一步地，巴片2包括相连的搭接部和延展部，搭接部搭接在相邻两电芯11的两个极柱111上，延展部延伸至电芯11的肩部112。
在垂直于第一方向和第二方向的第三方向上，液冷部31的长度与巴片2的长度的比值为0.1-2。由此，既避免了液冷部31的长度与巴片2的长度的比值过小，造成冷却效果差的问题。还避免了液冷部31的长度与巴片2的长度的比值过大，造成液冷部31与巴片2接触面积小，避免液冷部31处材料浪费的优点。进一步地，液冷部31的长度与巴片2的长度的比值可以为1，以便该电池模组组件100在冷却效率和造价上均达到较优的效果。
如图1至图6所示，本发明实施例的电池模组组件100还包括第二液冷板4，第二液冷板4用于设置于电池模组1上，且第二液冷板4与第一液冷板3相对设置。可以理解的是，第二液冷板4与第一液冷板3沿图1中所示的上下方向相对地设置在电池模组1的两侧。
本发明实施例的电池模组组件100，通过在电池模组1与第一液冷板3相对的一侧设置第二液冷板4，可以对电池模组1的另一面进行冷却。由此，该电池模组组件100进一步提升了对电池模组1的散热的效果和散热的均匀性。
如图12和图13所示，第一液冷板3内设有第一冷却流道311，第二液冷板4内设有第二冷却流道41，第一冷却流道311和第二冷却流道41中的每一者均具有用于冷却电池模组1的冷却介质。
本发明实施例的电池模组组件100，通过在第一液冷板3内设有第一冷却流道311，第二液冷板4内设有第二冷却流道41使得对冷却介质的流通路径进行控制，从而延长冷却介质在液冷板(第一液冷板3和第二液冷板4)中流动的时间，提高液冷板的冷却效果。由此，该电池模组组件100提升了对电池模组1的散热的效果。
可选地，第一液冷板3和第二液冷板4的形式可以是口琴管，也可以是冲压钎焊。
进一步地，如图1至图4所示，本发明实施例的电池模组组件100还包括第一汇流件和第二汇流件，第一冷却流道311和第二冷却流道41均包括多个沿第二方向延伸的分通道，第一汇流件对应地设置在第一液冷板3的延伸方向的两端，第二汇流件对应地设置在第二液冷板4的延伸方向的两端。
本发明实施例的电池模组组件100，通过第一冷却流道311和第二冷却流道41均包括多个沿第二方向延伸的分通道，从而扩大冷却流道在液冷板中流动时所覆盖的面积，从而更好的提高液冷板对电池模组1的冷却效果。并通过设置的第一汇流件和第二汇流件可以分通道内的冷却介质进行汇聚，不需要对每个分通道均设置连接管道，进而提升了连接和布设的便捷性。
如图1至图4所示，本发明实施例的电池模组组件100还包括进液管51和出液管52，进液管51、第一液冷板3、出液管52及第二液冷板4依次连通。
本发明实施例的电池模组组件100，通过设置的进液管51和出液管52将第一液冷板3和第二液冷板4连通以实现其内部冷却介质的循环，进而提升了对电池模组1冷却的均匀性和控制便捷性。
可选地，第一液冷板3可以具有多个，第一液冷板3可以并联或者串联后再与第二液冷板4连通。进一步地，第二液冷板4可以为一整个具有液腔的板体结构，该板体结构具有出液口和进液口。电池模组1可以具有多个呈排设置的电芯排，每个电芯排可以具有两个肩部112，每个肩部112上均对应设有第一液冷板3，多个第一液冷板3可以串联或并联后形成一个整体后再与第二液冷板4进行连通。
如图12所示，第二液冷板4沿第二方向具有相对设置的换热面板42和流道面板43，换热面板42和流道面板43形成第二冷却流道41，换热面板42的面积与电池模组1的贴合面积为S1,电池模组1与换热面板42连接一侧的面积为S2，S1与S2的比值为0.1-1。由此，可以避免第二液冷板4换热面积小造成冷却效果差的问题，又避免了换热面板42过大挤占电池包1000的内部空间的问题。
如图12所示，在第二方向上，换热面板42的厚度为D1，第二冷却流道41的尺寸为H1，0.02≤D1/H1≤5；流道面板43的厚度为D2，第二冷却流道41的尺寸为H1，0.02≤D2/H1≤5。由此，该电池模组组件100既避免了换热面板42和/流道面板43的厚度过大挤占了第二冷却流道41的空间造成的冷却效果差的问题，又避免了换热面板42和/流道面板43的厚度过小结构强度弱的问题。因此，该电池模组组件100兼具冷却效果好和结构强度高的优点。
可选地，换热面板42可以为平面板，流道面板43可以为波浪形结构板。换热面板42和流道面板43可以通过冲压钎焊、吹胀制造形成第二液冷板4，第二液冷板4也可以为口琴管或铝型材管。
可选地，为了保证第二液冷板4与电池模组1之间的连接强度，进一步地提升第二液冷板4与电池模组1之间的冷却效果，第二液冷板4与电池模组1之间可以通过导热垫、导热胶、结构胶、双面胶等各种换热介质增加热量的传导。
在第二方向上，第一液冷板3与巴片2连接的一侧(散热面312)厚度为D3，第一冷却流道311的尺寸为H2，0.02≤D3/H2≤2。由此，该电池模组组件100既避免了因第一液冷板3的厚度过大挤占第二冷却流道41的空间，造成冷却效果差的问题，又避免了第一液冷板3的厚度过小结构强度弱的问题。因此，该电池模组组件100兼具冷却效果好和结构强度高的优点。
本发明实施例的电池包1000包括导热层，该导热层设置在第一液冷板3和巴片2之间。由此，该电池包1000可以进一步提升了巴片2和第一液冷板3之间热传递效率。
进一步地，导热层可以为导热垫、导热胶、结构胶或双面胶。
本发明实施例的电池包1000可以包括壳体200和设置在壳体200内根据上述中任一项的电池模组组件100。
因此，本发明实施例的电池包1000具有快充能力好和提升散热能力的优点。
