本申请提供一种电池、用电装置、电池的制造方法及设备，该电池能够有效提高空间利用率，有利于提高电池的能量密度。
本申请提供了一种电池，包括：箱体，包括用于围合形成容置腔的侧壁；电池单体组，设置在所述容置腔内且包括多个电池单体，所述多个电池单体层叠排列；端板，设置在所述容置腔内且位于所述电池单体组和所述侧壁之间；电能引出件，用于将所述电池单体组的电能引出，所述电能引出件包括依次连接的第一段、第二段和第三段，所述第二段嵌入所述端板，所述第一段和所述第三段从所述端板伸出，所述第一段与所述电池单体组电连接；和/或采样单元，用于采集所述电池单体组的信号，所述采样单元贯穿所述端板，所述采样单元的一端与所述电池单体组连接。
上述技术方案中，电池的电能引出件嵌入端板和/或采样单元贯穿端板，这样，就可以省去在端板和箱体壁之间预留电能引出件、采样单元的过线空间，有利于提高电池的空间利用率，从而提高电池的能量密度；另外，电能引出件和/或采样单元集成于端板，使得端板对电能引出件和/或采样单元起到限位、紧固作用，有效提高电能引出件和采样单元的连接稳定性，降低电能引出件和采样单元因晃动、震动等原因中断连接的风险，从而降低因电能引出件连接断裂而造成短路、起火的事故的风险，有利于提高电池性能的稳定性。
在一些实施例中，所述第一段从所述端板的顶部伸出以与所述电池单体组电连接。
上述技术方案中，电能引出件的第一段从端板的顶部伸出，现有电池为了方便成组、维护，电池单体组的汇流件设置于整体电池结构的顶部，本申请电能引出件的第一段从端板的顶部伸出，便于缩短与电池单体组电连接的连接路径，且方便成组作业和维护。
在一些实施例中，所述第三段从所述端板的底部伸出。
上述技术方案中，电能引出件的第一段从端板的顶部伸出，第三段从端板的底部伸出，则电能引出件沿端板的厚度方向延伸，避免电能引出件占用箱体侧壁和端板之间的空间，端板和箱体侧壁之间无需预留过线空间，从而有效提高箱体内的空间利用率。并且，这样的设置方式避免在电池组装中将端板向下放置入箱体时，端板与箱体侧壁形成位置干涉。
在一些实施例中，所述箱体还包括底壁，所述侧壁围设在所述底壁的周围，所 述底壁设置有通孔，所述第三段从所述通孔伸出以将电能引出至所述箱体的外部。
上述技术方案中，第三段从箱体的底壁的通孔伸出，便于形成电池的电能引出部，以将电池的电能引出至箱体外部为用电装置供能。在箱体的底壁设置通孔，便于电能引出件的穿出作业，提高电池组装的便捷性。
在一些实施例中，所述电池还包括：绝缘件，所述绝缘件设置于所述通孔的孔壁和电能引出件之间，用于绝缘隔离所述通孔的孔壁和所述电能引出件。

在一些实施例中，所述电能引出件可拆卸地设置于所述端板，每个所述第一加强筋均开设有用于避让所述电能引出件的避让口。
上述技术方案中，每个第一加强筋均开设有用于避让电能引出件的避让口，组装时使电能引出件依次穿过每个第一加强筋的避让口即可将电能引出件装配在端板上，有利于降低组装作业难度；另外，将避让口错位设置即可使电能引出件具有弯折角，实施便捷，实用性强。

在一些实施例中，所述采样单元的一端从所述端板的顶部伸出以与所述电池单体组连接，所述采样单元的另一端从所述端板的底部伸出并穿出所述箱体以将所述信号引出至所述箱体的外部。
上述技术方案中，采样单元的一端从所述端板的顶部伸出以与所述电池单体组连接，所述采样单元的另一端从所述端板的底部伸出并穿出，这样的结构可以有效避免采样单元占用箱体侧壁和端板之间的空间，有效节省箱体内空间，从而提高箱体内的空间利用率。

电池单体包括电极组件和电解液，电极组件由正极极片、负极极片和隔离膜组成。电池单体主要依靠金属离子在正极极片和负极极片之间移动来工作。正极极片包括正极集流体和正极活性物质层，正极活性物质层涂覆于正极集流体的表面，未涂敷正极活性物质层的正极集流体凸出于已涂覆正极活性物质层的正极集流体，未涂敷正极活性物质层的正极集流体作为正极极耳。以锂离子电池为例，正极集流体的材料可以为铝，正极活性物质可以为钴酸锂、磷酸铁锂、三元锂或锰酸锂等。负极极片包括负极集流体和负极活性物质层，负极活性物质层涂覆于负极集流体的表面，未涂敷负极活性物质层的负极集流体凸出于已涂覆负极活性物质层的负极集流体，未涂敷负极活性物质层的负极集流体作为负极极耳。负极集流体的材料可以为铜，负极活性物质可以为碳或硅等。为了保证通过大电流而不发生熔断，正极极耳的数量为多个且层叠 在一起，负极极耳的数量为多个且层叠在一起。隔离膜的材质可以为PP(polypropylene，聚丙烯)或PE(polyethylene，聚乙烯)等。此外，电极组件可以是卷绕式结构，也可以是叠片式结构，本申请实施例并不限于此。
目前，从市场形势的发展来看，动力电池的应用越加广泛。动力电池不仅被应用于水力、火力、风力和太阳能电站等储能电源系统，而且还被广泛应用于电动自行车、电动摩托车、电动汽车等电动交通工具，以及军事装备和航空航天等多个领域。随着动力电池应用领域的不断扩大，其市场的需求量也在不断地扩增。
现有技术中的电池，一般会在电池箱体前部设置一根膨胀梁支撑端板，膨胀梁与电池箱体边框之间需要预留足够空间，以构成电池的输出部件的安装区域。这种结构的电池空间利用率低，严重影响电池能量密度的提升。
基于以上问题，为了提高电池的能量密度，申请人提供了一种电池，本申请的电池包括箱体、电池单体组、端板、电能引出件和/或采样单元，电池的电能引出件嵌入端板，即将电池的引出单元嵌设在端板上，这样，使得电池中在端板和箱体壁之间无需预留电池引出单元的过线空间，有利于提高电池的空间利用率，从而提高电池的能量密度；另外，电能引出件和/或采样单元集成于端板，使得端板对电能引出件和/或采样单元起到限位、紧固作用，有效提高电能引出件和采样单元的连接稳定性，降低电能引出件和采样单元因晃动、震动等原因中断连接的风险，从而降低因电能引出件连接断裂而造成短路、起火的事故的风险，有利于提高电池性能的稳定性。
本申请实施例公开的电池可以但不限用于车辆、船舶或飞行器等用电设备中，可以使用本申请公开的电池组成该用电设备的电源系统，这样，能够有效提升电池的使用寿命和使用性能。

在其他一些实施例中，电池100不仅可以作为车辆1000的操作电源，还可以作为车辆1000的驱动电源，代替或部分地代替燃油或天然气为车辆1000提供驱动动力。
其中，本申请的实施例所提到的电池是指包括一个或多个电池单体以提供更高的电压和容量的单一的物理模块。其中，多个电池单体之间可以串联、并联或者混联直接组成电池，混联指的是，多个电池单体中既有串联又有并联。多个电池单体也可以先串联、并联或者混联组成电池单体组，多个电池单体组再串联、并联或者混联组成电池。
请参照图2和图3，并进一步参照图4和图5，图2为本申请一些实施例提供的电池的第一视角的爆炸图，图3为本申请一些实施例提供的电池的第二视角的爆炸图，图4为图2所示的A部分的局部放大图，图5为图3所示的B部分的局部放大图。本申请一些实施例提供一种电池100，电池100包括箱体20、电池单体组10、端板30、电能引出件40和/或采样单元50，箱体20包括用于围合形成容置腔211的侧 壁21，电池单体组10设置在容置腔211内且包括多个电池单体11，多个电池单体11层叠排列。端板30设置在容置腔211内且位于电池单体组10和侧壁21之间。电能引出件40用于将电池单体组10的电能引出，电能引出件40包括依次连接的第一段41、第二段42和第三段43，第二段42嵌入端板30，第一段41和第三段43从端板30伸出，第一段41与电池单体组10电连接。
采样单元50用于采集电池单体组10的信号，采样单元50贯穿端板30，采样单元50的一端与电池单体组10连接。
其中，箱体20用于为电池单体组10提供容纳空间，以对电池单体组10起到收纳和保护作用，箱体20可以为方体结构，也可以为圆柱体或者椭圆柱体等。箱体20包括围合形成容置腔211的侧壁21，其侧壁21根据箱体20形状的不同可以采用多种结构，示例性的，请参照图2，图2为本申请一些实施例提供的电池100的第一视角的爆炸图，箱体20可以包括顶壁22、侧壁21和底壁23，顶壁22和底壁23相对设置，侧壁21围设在底壁23的周围且侧壁21为两端开口的空心结构，侧壁21的内腔形成容置腔211，侧壁21连接顶壁22和底壁23，侧壁21、顶壁22和底壁23共同限定出可以容纳电池单体组10的容纳空间。
在一些实施例中，顶壁22和侧壁21可以一体成型并形成壳体，壳体的一端具有开口，底壁23与侧壁21分体设置，底壁23构成盖体结构，底壁23覆盖壳体的开口以将电池单体组10封闭在壳体内部。
在其他实施例中，也可以底壁23和侧壁21一体成型并形成壳体，壳体的一端具有开口，顶壁22与侧壁21分体设置，顶壁22构成盖体结构，顶壁22覆盖壳体的开口以将电池单体组10封闭在壳体内部。
示例性的，如图2所示，箱体20可以包括分体设置的顶壁22、底壁23和侧壁21，侧壁21形成壳体，壳体的两端开口，底壁23和顶壁22分别覆盖壳体的两个开口以形成一个封闭的用于容纳电池单体组10的空间。
其中，侧壁21合围形成的壳体可以为长方形、正方形或其他形状，箱体20可由金属材料制成，诸如铝、铝合金或者镀镍钢。在本申请的一些实施例中，箱体20可以为六面体，顶壁22和底壁23可以为正方形或者长方形板状结构。
具体而言，箱体20的宽度方向沿第一方向X延伸，长度方向沿第二方形Y延伸，高度方向沿第三方向Z延伸。沿第三方向Z，顶壁22位于侧壁21的上方，底壁23位于侧壁21的下方。
电池单体组10设置在容置腔211内，电池单体组10包括多个电池单体11，多个电池单体11之间可串联或并联或混联(混联是指多个电池单体11中既有串联又有并联)在一起形成电池单体组10，电池单体组10设置于箱体20的容置腔211；当然，电池100也可以包括多个电池单体组10，多个电池单体组10再串联或并联或混联组成电池100，也就是说，容置腔211内可以设置单个电池单体组10或多个电池单体组10。其中，每个电池单体11可以为二次电池100或一次电池100；还可以是锂硫电池100、钠离子电池100或镁离子电池100，但不局限于此。电池单体11可呈圆柱体、扁平体、长方体或其它形状等。
端板30用于电池单体组10的限位件及紧固件，以对电池单体组10的多个电池单体11起到紧固限位作用，且可以限制电池单体组10在箱体20内移动。
端板30的材质可以为尼龙、尼龙和玻璃纤维等塑料材质，也可为铝、铝合金等常规金属材质，端板30可为注塑件，也可以为压铸件。
在本申请的一些实施例中，电池单体组10的多个电池单体11沿箱体20的长度方向(第二方向Y)排列，端板30设置于电池单体组10的沿第二方向Y的两端且位于电池单体组10和侧壁21之间。
电能引出件40用于将电池单体组10的电能引出，可以理解的是，电能引出件40应该具有导电性，电能引出件40的材质可以为导电性能好的金属材质。
“电能引出件40的第二段42嵌入端板30”可以采用多种实施结构，比如，电能引出件40可以与端板30一体成型，电能引出件40也可以可拆卸的装配于端板30。 其中，端板30与电能引出件40的可拆卸的方式也可以有多种，比如：端板30可以设置卡槽，电能引出件40卡入卡槽而与端板30卡接；电能引出件40通过胶体粘合于端板30；电能引出件40通过紧固件固定于端板30等。
本申请实施例并不对电能引出件40的数量做限制，一个端板30上可以嵌入一个电能引出件40，也可以嵌入多个电能引出件40。
采样单元50用于采集电池单体组10的信号，其包括但不限于采集电池单体组10的电压信号、温度信号等信号，采样单元50可以连接至电池100的控制系统，便于电池100的控制系统收集、监测电池100的电压、温度等信息。
可以理解的是，采样单元50贯穿端板30的实施方式有多种，采样单元50与端板30可以活动配合也可以相对位置固定。具体而言，采样单元50可以与端板30一体成型，也可以与端板30分体设置并通过卡接、螺接、胶粘等方式固定于端板30，或者在端板30设置供采样单元50穿过的通道34，使采样单元50通过通道34贯穿端板30。
同样的，本申请实施例并不对采样单元50的种类和数量做限制，电池100可以包括一个采样单元50贯穿端板30，也可以包括多个采样单元50贯穿端板30。
电池100的电能引出件40嵌入端板30，采样单元50贯穿端板30，使得电池100中在端板30和箱体20壁之间无需预留电能引出件40、采样单元50的过线空间，有利于提高电池100的空间利用率，从而提高电池100的能量密度；另外，电能引出件40和/或采样单元50集成于端板30，使得端板30对电能引出件40和/或采样单元50起到限位、紧固作用，有效提高电能引出件40和采样单元50的连接稳定性，降低电能引出件40和采样单元50因晃动、震动等原因中断连接的风险，从而降低因电能引出件40连接断裂而造成短路、起火的事故的风险，有利于提高电池100性能的稳定性。
电能引出件40的第一段41和第三段43从端板30上伸出形成自由的连接端，第一段41和第三段43从端板30上的伸出方向可以根据电池100的整体结构进行灵活设置，比如，第一段41的伸出位置可以靠近电池单体组10的电能输出部，第三段43的伸出位置可以靠近设置在箱体20上的与电池100外连通的通道34。
在一些实施例中，第一段41从端板30的顶部伸出以与电池单体组10电连接，第三段43从端板30的底部伸出。
在常规电池100中，为了方便组装和维护，电池单体组10的汇流件设置于整体电池100结构的顶部，本申请电能引出件40的第一段41从端板30的顶部伸出，便于缩短与电池单体组10电连接的连接路径，且现有技术的电池100组装过程中，需要将端板30向下移动装入箱体20，第一段41和第三段43分别自端板30的顶部和底部伸出，可以有效避免对端板30的组装形成干涉，且避免电能引出件40占用电池100箱内空间。
可以理解的是，为了将电池单体组10的电能引出电池100外部，电能引出件40的第三段43从端板30的底部伸出后可以穿出箱体20，以将电池单体组10的电能引出电池100外部。
在一些实施例中，请参照图2和图5，箱体20还包括底壁23，侧壁21围设在底壁23的周围，底壁23设置有通孔231，第三段43从通孔231伸出以将电能引出至箱体20的外部。
其中，通孔231的形状可以与第三段43的横截面仿形设置，通孔231可以与第三段43间隙配合也可以与第三段43过盈配合，当第三段43与通孔231过盈配合时，通孔231对第三段43起到限位固定作用，进一步提高电能引出件40的连接稳定性。
可以理解的是，电能引出件40具有导电性能，电能引出件40与通孔231过盈配合时，通孔231的孔壁可以为绝缘材质，以使电能引出件40与箱体20绝缘隔离。
第三段43从箱体20的底壁23的通孔231伸出，便于将电池100的电能引 出至箱体20外部为用电装置供能。在箱体20的底壁23设置通孔231，便于电能引出件40的穿出作业，提高电池100组装的便捷性。
在一些实施例中，请继续参照图5，电池100还包括绝缘件60，绝缘件60设置于通孔231的孔壁和电能引出件40之间，用于绝缘隔离通孔231的孔壁和电能引出件40。
因为电能引出件40的第三段43经通孔231穿出箱体20，所以绝缘件60设置于通孔231的孔壁和电能引出件40的第三段43之间，绝缘件60通过限制电能引出件40与通孔231孔壁的接触而达到电能引出件40与箱体20绝缘的目的。
绝缘件60的实施结构有多种，比如，绝缘件60可以为一个独立结构，绝缘件60可以形成于电能引出件40的第三段43的外周面且凸出于电能引出件40的第三段43的外周面，绝缘件60与电能引出件40的相对位置固定，且电能引出件40的第三段43经通孔231穿出后，绝缘件60穿设于通孔231内并隔离电能引出件40和通孔231的孔壁。
在其他一些实施例中，绝缘件60也可以形成在孔壁上，比如绝缘件60可以为环形结构，绝缘件60穿设在通孔231内与箱体20固定连接，绝缘件60的外周壁与通孔231的内周壁抵接，电能引出件40从绝缘件60的内腔穿出，绝缘件60的周壁隔离电能引出件40和通孔231的孔壁。
其中，绝缘件60的材料可以由任意一种或多种常规的绝缘材质制成，比如塑胶、橡胶、陶瓷等。
在一些实施例中，电能引出件40和通孔231之间的间隙可以通过绝缘件60密封，比如，当绝缘件60形成于电能引出件40的外周面时，电能引出件40的外周面可以与通孔231的孔壁过盈配合，使得绝缘件60在隔离电能引出件40和通孔231的同时同步密封电能引出件40与通孔231的间隙，这样的结构，一方面可以防止杂质经通孔231与电能引出件40之间的间隙进入电池100箱体20内，也可以防止箱体20内产生的高温高压气体沿电能引出件40经通孔231流出电池100箱体20外。
绝缘件60与通孔231可以间隙配合也可以过盈配合，当绝缘件60与通孔231过盈配合时，不仅可以固定电能引出件40和箱体20的相对位置，也可以将电能引出件40和通孔231的间隙密封。
在箱体20的通孔231的孔壁和电能引出件40之间设置绝缘件60，形成箱体20与电能引出件40之间的绝缘防护，避免电能引出件40与箱体20短路，并保证箱体20的绝缘性，降低箱体20漏电风险。
在一些实施例中，请参照图4，绝缘件60与端板30一体成型。
可以理解的是，绝缘件60设置于通孔231的孔壁和电能引出件40之间，绝缘件60与端板30一体成型，则电能引出件40的第三段43从绝缘件60穿出。
绝缘件60与端板30一体成型，有利于提高电池100组装的便捷性，且相对于绝缘件60分体设置的方式，绝缘件60一体成型于端板30的结构具有较高的防呆性能，可有效防止在电池100组装过程中因组装工序遗漏而漏装绝缘件60的风险，有利于简化组装流程，降低组装不良率和返工率。并且，绝缘件60一体成型于端板30的设计对电能引出件40起到加固及全面绝缘防护作用，绝缘可靠性强。
在一些实施例中，请参照图6，图6为本申请一些实施例提供的端板30的第一视角的轴测图，端板30和电能引出件40注塑成型为一体。
可以理解的是，电能引出件40包括依次连接的第一段41、第二端和第三段43，第二段42嵌入端板30，在本实施例中，端板30和电能引出件40注塑成型为一体指的是电能引出件40的第二段42与端板30注塑成型为一体。
具体而言，端板30应包括注塑部，端板30的注塑部包裹电能引出件40的第二段42，使得端板30与第二段42注塑成型为一体。其中，端板30的整体结构可以全部为注塑件，也可以由金属件和注塑部一体成型，端板30的塑胶部包裹第二段42。
电能引出件40具有导电性能，将电能引出件40与端板30注塑一体成型，便于端板30的注塑件部分对电能引出件40直接起到绝缘防护作用，避免电能引出件 40短路；另外，端板30对电能引出件40起到牢固的限位作用，进一步提高电能引出件40连接的稳定性；同时，一体注塑成型后，电能引出件40和端板30的连接处密封，当电池100内有高温高压气体产生时，气体无法直接冲击电能引出件40，从而可以有效避免高温高压气体融化电能引出件40而使电池100短路、起火的风险，有利于提高电池100的安全性能。
在一些实施例中，请参照图8，图8为本申请一些实施例提供的采样单元50贯穿端板30的状态示意图，电能引出件40可拆卸地连接于端板30，在电能引出件40的延伸方向上，电能引出件40至少折弯两次。
如前，端板30与电能引出件40的可拆卸的方式也可以有多种，比如：端板30可以设置卡槽，电能引出件40卡入卡槽而与端板30卡接；电能引出件40通过胶体粘合于端板30；电能引出件40通过紧固件固定于端板30等。
因电能引出件40与端板30可拆卸连接，则电能引出件40与端板30的连接处必然存在间隙，当电池100内产生高温高压气体时，高温高压气体可能会经端板30与电能引出件40之间的间隙顺着电能引出件40流动，从而存在高温高压气体融化电能引出件40的风险，具有较大的安全隐患。
而本实施例中，电能引出件40至少折弯两次，使得电能引出件40的延伸方向发生至少两次改变，通过改变电能引出件40的延伸方向而有效降低气体沿电能引出件40流动的风险。
电能引出件40可以折弯多次，即可折弯两次、三次、四次甚至更多次。示例性的，请参照图7，电能引出件40折弯两次。
电能引出件40可拆卸地连接于端板30，端板30和电能引出件40可以分体生产后再行组装，有利于降低工艺难度和生产成本。而电能引出件40至少折弯两次的结构使得电能引出件40具有至少两个折弯角44，即改变两次电能引出件40的延伸方向，当电池100内有高温高压气体产生时，电能引出件40的折弯有利于增加气体流通阻力，阻止气体沿电能引出件40和端板30之间的间隙顺着电能引出件40流道，从而可以有效避免高温高压气体融化电能引出件40而使电池100短路、起火的风险，有利于提高电池100的安全性能。
在一些实施例中，电能引出件40的折弯角44的折弯角度为40°～130°。也就是说，电能引出件40折弯后形成有折弯角44，折弯角44的折弯角度为40°～130°。在一些实施例中，电能引出件40的折弯角44的折弯角度为75°～100°。
示例性的，如图7所示，电能引出件40的折弯角44度为90°。
电池100中一般采用导电金属作为电能引出件40，折弯角44度过小容易影响电能引出件40的结构强度，存在电能引出件40断裂风险，而折弯角44度过大则无对气流形成有效的阻拦作用，本实施例将电能引出件40的折弯角44度控制在40°～130°之间，有利于在保证电能引出件40结构强度的同时对高温高压气体起到良好的阻拦作用。将电能引出件40的折弯角44度控制在75°～100之间，能进一步提高对高温高压气体的阻拦作用。
在一些实施例中，请继续参照图6和图7，端板30包括端板本体31和多个第一加强筋32，端板本体31具有朝向电池单体组10的第一面311和背离电池单体组10的第二面312，第一面311与电池单体组10抵接。多个第一加强筋32形成在第二面312且与侧壁21抵接，多个第一加强筋32沿上下方向间隔设置。其中，第二段42贯穿多个第一加强筋32。
第一加强筋32的作用在于提高端板本体31的结构强度，第一加强筋32可以是类似于条形的结构，也可以是类似于板状的结构，可以为平面结构，也可以为曲面结构，示例性的，如图6所示，第一加强筋32呈平面的板状结构。第一加强筋32与端板本体31可以一体成型，也可以采用焊接、螺接等方式组装形成。
在一些实施例中，端板30还可以包括多个第二加强筋33，多个第二加强筋33形成在第二面312且与侧壁21抵接，多个第二加强筋33与多个第一加强筋32交叉设置，每个第二加强筋33沿竖直方向延伸。
与第一加强筋32相似，第二加强筋33可以是类似于条形的结构，也可以是类似于板状的结构，可以为平面结构，也可以为曲面结构，示例性的，如图6和图7所示，基于第一加强筋32为平面板状的实施形式，第二加强筋33也为平面板状结构。
端板30包括第一加强筋32和与第一加强筋32较叉设置的第二加强筋33，第一加强筋32和第二加强筋33形成网状结构，有利于进一步提高端板30的结构强度。
可以理解的是，第二段42贯穿多个第一加强筋32，则多个第一加强筋32至少与第二段42接触的位置为绝缘材质，以保证电能引出件40与端板30之间的绝缘，为了简化生产工艺，第一加强筋32可以均为绝缘材质，甚至第一加强筋32和端板本体31均为绝缘材质。
基于“端板30和电能引出件40注塑成型为一体”的实施形式，电能引出件40可以与多个第一加强筋32一体成型。
基于“电能引出件40可拆卸地连接于端板30”的实施形式，电能引出件40可以可拆卸地连接于多个第一加强筋32。
端板30包括端板本体31和形成在端板本体31上的加强筋，加强筋的设置有效提升端板30的结构强度，提高端板30的抗变形性。同时，相较于通过增加端板30整体厚度而提高端板30强度的方式，加强筋的设置在保证端板30的结构强度的同时降低端板30的整体重量和材料损耗，有利于降低电池100的重量和材料成本。
并且，电能引出件40贯穿多个第一加强筋32，有利于降低电能引出件40与端板30的成组难度，在“电能引出件40与可拆卸设置于端板30”的实施模式中，多个第一加强筋32对电能引出件40形成多个限位部，便于实现电能引出件40的固定和弯折；同时，电能引出件40贯穿多个第一加强筋32，便于直观观察电能引出件40在端板30上的状态，易于维护。
在一些实施例中，请参照图7，图7为本申请一些实施例提供的端板30的第二视角的轴测图，电能引出件40可拆卸地设置于端板30，每个第一加强筋32均开设有用于避让电能引出件40的避让口324。
每个第一加强筋32均开设有用于避让电能引出件40的避让口324，组装时使电能引出件40依次穿过每个第一加强筋32的避让口324即可将电能引出件40装配在端板30上，有利于降低组装作业难度；另外，将避让口324错位设置即可使电能引出件40具有弯折角，实施便捷，实用性强。
在其他一些实施例中，电能引出件40还可以通过设置在第一加强筋32上的安装通道贯穿端板30，具体而言，每个第一加强筋32可以设置开口，多个开口相互连通形成一个贯穿多个第一加强筋32的安装通道，电能引出件40的第二段42穿过安装通道，从而使得电能引出件40贯穿端板30。
在一些实施例中，电能引出件40可以包括电能引出件40本体和形成在电能引出件40本体外周面且凸出于本体的外周面的凸缘，当第二段42穿入安装通道后，凸缘用于覆盖开口和电能引导件之间的间隙，凸缘的设置对电能引出件40在安装通道内的位置起到限位作用，同时凸缘也可以起到阻挡电池100内的高温高压气体沿安装通道流通的作用，避免高温高压气体损坏电能引出件40。
在一些实施例中，电池100还可以包括输出极70，输出极70的一端与电池单体组10电连接，用于输出电池单体组10的电能，输出极70的另一端与第一段41电连接。

电池100设置输出极70，输出极70连接电池单体组10和电能引出件40，有利于提高电池100模块化组装程度，且便于电池100维护。
在一些实施例中，请再次参照图2和图3，电池100还可以包括高压配电盒 80，高压配电盒80设置于箱体20外，第三段43伸出箱体20以与高压配电盒80连接。

电能引出件40的第三段43伸出箱体20与高压配电盒80连接，高压配电盒80在电池100的充电和放电过程中，起到保护动力电池100系统和动力传输分配的作用。
在一些实施例中，请参照图8和图9，图8为本申请一些实施例提供的采样单元50贯穿端板30的状态示意图，图9为图8所示的采样单元50贯穿端板30的配合结构示意图。端板30设置有供采样单元50穿过的通道34，通道34贯穿端板30且由端板30的顶部延伸至底部。
端板30设置有通道34，采样单元50穿过通道34即可限位于端板30，无需改变采样单元50的结构即可简单快速的将采样单元50集成限位于端板30，操作简便可实施性强，且便于灵活加减、调整采样单元50，实用性强。
在一些实施例中，采样单元50的一端从端板30的顶部伸出以与电池单体组10连接，采样单元50的另一端从端板30的底部伸出并穿出箱体20以将信号引出至箱体20的外部。
基于“端板30包括端板本体31和多个第一加强筋32”的实施形式，通道34可以贯穿多个第一加强筋32，使得采样单元50的一端从顶部加强筋321伸出以与电池单体组10连接，采样单元50的另一端从底部加强筋323伸出并穿出箱体20以将信号引出至箱体20的外部。
同时，采样单元50的另一端穿出箱体20后，可以直接连接至用电装置的控制系统，也可以连接至为电池100设置的单独的控制系统。
可以理解的是，请再次参照图5，可以在箱体20的底壁23设置供采样单元50穿出的通槽232，采样单元50的另一端从通槽232穿出箱体20的底壁23。
在一些实施例中，基于“电池100包括高压配电盒80，高压配电盒80设置于箱体20外，第三段43伸出箱体20以与高压配电盒80连接”的实施形式，电池100的控制系统可以集成于高压配电盒80的盒体内，也就是说，电能引出件40的第三段43和采样单元50的一端穿出箱体20后均连接至高压配电盒80的盒体内。
同样的，高压配电盒80可以与箱体20的底壁23密封连接，高压配电盒80的内腔可以与箱体20底壁23上的供采样单元50穿出的通槽232连通，采样单元50经通槽232伸出箱体20后直接进入高压配电盒80的盒体的内腔，从而保证箱体20的密封性。
在一些实施例中，采样单元50与箱体20的通槽232的槽壁之间也可以设置绝缘结构，与电能引出件40和通孔231之间的绝缘件60相似，采样单元50的绝缘结构可以固定于采样单元50也可以覆盖通槽232的槽壁，采样单元50的绝缘结构以及材质可以参照电能引出件40的绝缘件60的实施结构，在此不再赘述。
在一些实施例中，采样单元50与箱体20的连接处可以设置密封件，以实现采样单元50与箱体20的密封连接。
在一些实施例中，采样单元50包括采样单元本体51和遮挡部52，遮挡部52形成于采样单元本体51的外周面且凸出于采样单元本体51的外周面，遮挡部52用于覆盖采样单元本体51和通道34内壁之间的间隙。
示例性的，如图8和图9所示，采样单元50的一端从顶部加强筋321伸出以与电池单体组10连接，遮挡部52位于顶部加强筋321上方，采样单元50贯穿多个第一加强筋32后，遮挡部52覆盖采样单元本体51和顶部加强筋321之间的间隙。
当电池100内产生高温高压气体时，遮挡部52的设置可以有效避免气体沿采样单元50和端板30之间的间隙流通，从而降低高温高压气体损坏采样单元50的风 险，且避免高温高压气体随采样单元50和端板30之间的间隙在箱体20内流窜，影响电池100内气体的正常定向排出。
根据本申请的一些实施例，请继续参照图8和图9，并进一步参照图10和图11，图10为本申请一些实施例提供的电池100的局部主视剖面图，图11为图10所示的俯视图。电池100还可以包括排气口212和导流通道35。
具体而言，箱体20的侧壁21设置排气口212，导流通道35设置于端板30，导流通道35连通排气口212和容置腔211。这样的结构，便于在提高电池100箱体20内的空间利用率后，能够保证电池100排气的通畅性，且对电池100的排气起到定向引导作用，提高排气的可控性。
在一些实施例中，导流通道35可以包括竖向通道351和横向通道352，竖向通道351的上端与容置腔211连通，横向通道352沿端板30的厚度方向的一端与竖向通道351连通，另一端与排气口212连通。
因竖向通道351的上端与容置腔211连通，所以端板30的上端对应气体排出箱体20时的来气方向，在此基础上，“电能引出件40可拆卸地设置于端板30，每个第一加强筋32均开设有用于避让电能引出件40的避让口324，在电能引出件40的延伸方向上，电能引出件40至少折弯两次”的实施形式中，顶部加强筋321的避让口324和与顶部加强筋321相邻的中部加强筋322上的避让口324可以错位设置，以使电能引出件40穿过顶部加强筋321时进行折弯，方便从气体流通的上游阻拦气体。
基于“端板30包括端板本体31和多个第一加强筋32，端板本体31具有朝向电池单体组10的第一面311和背离电池单体组10的第二面312，第一面311与电池单体组10抵接，多个第一加强筋32形成在第二面312且与侧壁21抵接，多个第一加强筋32沿上下方向间隔设置”的实施模式，多个第一加强筋32可以包括顶部加强筋321、中间加强筋和底部加强筋323，竖向通道351可以沿竖直方向至少贯穿顶部加强筋321，横向通道352形成在相邻两个第一加强筋32之间，竖向通道351的上端与排气间隙连通，横向通道352连通竖向通道351和排气口212。

其中，第一开口3211、第二开口3221的形状可以是多样的，比如矩形、圆形、椭圆形等，第一开口3211和第二开口3221的形状可以相同也可以不同，沿竖直方向，第二开口3221的投影可以完全落入第一开口3211的投影，也可以第二开口3221的投影部分落入第一开口3211的投影。
示例性的，请参照图9，第一开口3211和第二开口3221均为矩形，第二开口3221的投影完全落入第一开口3211的投影。
顶部加强筋321开设有面积较大的第一开口3211，第一开口3211能够对气流起到集流作用，引导气体快速进入竖向通道351。
基于“端板30还包括多个第二加强筋33，形成在第二面312且与侧壁21抵接，多个第二加强筋33与多个第一加强筋32交叉设置，每个第二加强筋33沿竖直 方向延伸”的实施形式，竖向通道351可以位于任一相邻两个第二加强筋33之间，也可以横跨一个或多个第二加强筋33。
在一些实施例中，如图9所示，竖向通道351位于相邻两个第二加强筋33之间。
竖向通道351设置在相邻两个第二加强筋33之间，相邻两个第二加强筋33对气流的横向流通起到拦截限位作用，进一步提高导流通道35对气流的导向效果。
在一些实施例中，如图10所示，电池100还可以包括泄压机构90，泄压机构90设置于侧壁21，泄压机构90的一端与排气口212连通，泄压机构90被配置为在电池100的内部压力达到阈值时泄放内部压力。

电池100设置与排气口212连通的泄压机构90，通过泄压机构90有效控制电池100的泄放频率，且泄压机构90处于未制动状态时，能够有效防止灰尘、水渍等杂质经排气口212进入箱体20。
