具体实施方式
实施本申请实施例的任一技术方案必不一定需要同时达到以上的所有优点。
为了使本领域的人员更好地理解本申请实施例中的技术方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请实施例一部分实施例，而不是全部的实施例。 基于本申请实施例中的实施例，本领域普通技术人员所获得的所有其他实施例，都应当属于本申请实施例保护的范围。
在一种实现方式中，电池储能装置基于电芯、模组、电池包三个层级进行集成，通过相对独立的零部件实现相对独立的功能。例如，利用相对独立的结构零件用于提供整个电池储能装置承载的功能；利用相对独立的电池模组零件集成一定数量的电芯；利用冷板提供冷却功能等。这样的电池储能装置层级较多，零件数量多，采用工艺种类多，结构复杂，集成效率不高，成本较高，也有安全隐患。
在另一种实现方式中，对电池模组层级进行弱化或取消，利用电芯直接集成电池包。例如，电芯直接通过胶黏剂固定于冷板或者其他结构零件上。这种电池储能装置同样通过相对独立的零部件实现相对独立的功能，如电池储能装置中仍然存在托盘、冷板、上盖等相对独立的零部件，集成效率提高有限，工艺相对复杂，零件数量也比较多，而且，电池包中的电芯较多，都放置在一起，如果一个电芯发生热失控，就会蔓延到其他电芯，具有较大的安全隐患。
而且以上两种实现方式，电池储能装置的电量较为固定，产品设计较难实现空间及后期扩展。当使用场景对电池储能装置的物理边界、电量等需求发生改变时，较难实现灵活匹配，一般需要重新开发。开发周期长，成本高。
下面结合本申请实施例附图进一步说明本申请实施例具体实现。

电芯组103通过结构主体101的开口置于结构主体101的空腔内；
支撑件102用于支撑结构主体101以防护置于结构主体101的空腔内的电芯组103。
本申请实施例的电池储能模块及电池储能装置，利用结构主体内部的空腔容纳电芯组，由于支撑件用于支撑所述结构主体以防护置于所述结构主体的空腔内的电芯组，所述电池储能模块能够具有较强的抗冲击能力，无需设置在防护托盘内即可单独应用于整车环境中。
可选地，参见图2a——2g，所述支撑件102为所述结构主体101的一部分 或者设置于所述结构主体101的任一外壁。

图2e为所述结构主体101与所述支撑件102共同组成所述空腔，所述结构主体101仅为外壁，底部开口以及中间隔板与所述支撑件102实现组装。
图2f为所述结构主体101组成所述空腔，所述支撑件102置于所述结构主体101底部。
图2g为所述结构主体101与所述支撑件102共同组成所述空腔，所述结构主体101与所述支撑件102为整体结构，所述支撑件102为底部具有凹槽的支撑实体。
本申请所述支撑件102设置于所述结构主体101的任一外壁，能够实现所述支撑件102与所述结构主体101共同增加所述空腔的抗冲击能力。
具体地，所述结构主体101与所述支撑件102为一体成型或者分别组装。
所述结构主体101与所述支撑件102采用一体成型，降低了制作工艺的复杂度，减少了零件数量的同时提升了结构的稳定性。例如，一种典型的实现方式是通过金属挤压工艺一体成型，这种成型方式零件数量少，整体结构强度好，成本较低。
所述结构主体101与所述支撑件102采用组装方式，令所述结构主体101和所述支撑件102可以分别制造，提供生产工艺的灵活性。例如，通过焊接、螺栓连接等方式组合为一个整体，本申请对此不作限制。
图3为本申请实施例提供的一种结构主体的结构示意图，如图3所示，可选地，在本申请的一个实施例中，结构主体101还包括隔断梁1011，隔断梁1011将结构主体101的空腔隔断为至少一个子空腔，每一个子空腔可以容纳至少一个电芯组103。
可选地，本申请实施例中，所述支撑件102和/或所述隔断梁1011为包括至少一子腔室的腔体结构。
腔体结构起到防护缓冲的作用，其增加了结构主体101抵御外部碰撞的强度和缓冲区域，有利于保护结构主体101内部空腔中的电芯组103。如图4所示，示出了支撑件102的腔体结构。图4中，还可以观察到，结构主体101内部的空腔可以有至少一个，例如，结构主体101内部的空腔可以是一个空腔；也可以是并排的两个空腔；也可以是并排的三个空腔；也可以是四个空腔，上下两排，每排两个空腔；当然，此处只是示例性说明，并不代表本申请局限于此。
结构主体101的空腔可以是柱形，空腔的横截面(即结构主体101内壁的纵截面图形)可以是圆形、矩形、体形等，本申请对此不做限制，结构主体101外壁的纵截面图形可以和内壁的纵截面图形相同或者不同。

腔体结构不仅可以对电芯组103进行防护，增加缓冲区域，还可以容纳热管理介质，对电芯组103进行降温，将防护功能和冷却功能都利用集成在结构主体101内部的腔体结构实现，不需要增加单独的防护组件和热管理组件，进一步减少了零部件的数量，制造更加便捷，结构稳定性更好。
可选地，在本申请的另一实施例中，所述结构主体101的空腔包括热管理介质通道，所述热管理介质通道用于容纳对所述电芯组进行冷却的热管理介质。
所述结构主体101的空腔如为密封空腔，可选地，参见图5，将所述空腔作为热管理介质通道，注入对所述电芯组进行冷却的热管理介质，形成浸没式 冷却。热管理介质为冷却液或者相变材料，所述结构主体101的空腔体积能够满足浸没式冷却的需求，成本低廉且可靠性高。
可选地，本申请实施例中，本申请还包括：端板104，所述端板104与所述结构主体101将所述电芯组103密封在所述结构主体101的空腔内。
具体地，例如，结构主体101为长条状，结构主体101的开口设置于结构主体101的两端，结构主体101可以有两个开口，也可以有一个开口。
结构主体101的开口设置于结构主体101的两端，端板102连接于结构主体101的开口处，因此，端板102与结构主体101之间需要密封的部位尺寸很小，易于密封，密封效果更好，而且电池储能模块10只是容纳电芯组103，尺寸远远小于普通的电池储能装置，因此，密封性相比于普通电池储能装置会进一步提高。
图6为本申请实施例提供的一种端板的结构示意图，如图6所示，可选地，在本申请的一个实施例中，端板104上设置有至少一个外接接口1041，外接接口1041用于连接外部设备。
外接接口1041可以包括电气外接接口、热管理接口、机械外接接口等，端板104上还可以设置有用于维修的维修窗口。电气外接接口可以接入电气部件，热管理外接接口可以接入热管理部件，机械外接接口可以接入机械部件。
端板104可以提供对电芯组103的约束力，约束电芯组103在结构主体101的空腔内的位置。
参见图1b所示，可选地，在本申请的任一实施例中，电芯组103包括至少一电芯1031、约束体1032。
电芯指的是单个含有正、负极的电化学单元，电芯可以分为铝壳电芯、软包电芯(又称“聚合物电芯”)、圆柱电芯等，本申请对电芯的定义不作限制，只要是有正负极的电化学单元即可。
约束体1032设置在电芯组103的两端对电芯1031起约束作用。
可选地，在所述电芯之间设置弹性组件1033，弹性组件1033可以减少电芯1031之间的摩擦，对电芯1031起到保护作用。
可选地，在本申请的任一实施例中，如图1b所示，电芯组103还包括约束条1034，约束条1034与约束体1032固定连接，并对电芯1031起约束作用。约束条1034上可以设置凸起，以减少电芯组103推入结构主体101的空腔时的摩擦力，也可在约束条1034表面喷涂涂层以降低摩擦系数。还可以在约束条 1034上制作特殊形状以容纳其他高分子材料作为电芯组103推入时的接触面，减少约束条1034与结构主体101内壁之间的摩擦力的方法有很多，本申请对此不作限制，例如，也可以对结构主体101内壁喷涂涂层。电芯组103与结构主体101的组装方式取决于结构主体101的结构，结构主体101是一体成型的，则可以从结构主体101的开口处推入电芯组103。
可选地，在本申请的任一实施例中，如图1b所示，电芯组103还包括信号采集组件1035，信号采集组件1035与电芯1031电连接。信号采集组件1035可以对电芯1031进行监控，在电芯1031出现热失控等异常情况下发出信号告警。

需要说明的是，其他功能模块，也可以采用类似电芯组103的形式，推入结构主体101，从而使电池储能模块10具有扩展功能，例如，如图7所示，电池控制模块可以通过结构主体101的开口推入结构主体101的空腔，电池控制模块可以与电芯组103电连接。
本申请实施例的电池储能模块10，利用结构主体101内部的空腔容纳电池组，由于开口在结构主体101两端，因此开口处端板102和结构主体101之间需要进行密封的尺寸较小，在工艺上更容易实现，而且密封效果更好。
实施例二、

本申请实施例的电池储能装置，利用结构主体内部的空腔容纳电池组，由于开口在结构主体两端，因此开口处端板和结构主体之间需要进行密封的尺寸较小，在工艺上更容易实现，而且密封效果更好。
