本申请中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本申请中字符“/”，一般表示前后关联对象是一种“或”的关系。
本申请中出现的“多个”指的是两个以上(包括两个)，同理，“多组”指的是两组以上(包括两组)，“多片”指的是两片以上(包括两片)。
本申请中，电池单体可以包括锂离子二次电池、锂离子一次电池、锂硫电池、钠锂离子电池、钠离子电池或镁离子电池等，本申请实施例对此并不限定。电池单体可呈圆柱体、扁平体、长方体或其它形状等，本申请实施例对此也不限定。电池单体一般按封装的方式分成三种：柱形电池 单体、方体方形电池单体和软包电池单体，本申请实施例对此也不限定。

目前集成有热管理部件的电池的箱体采用的是将热管理部件与底护板单独独立装配，也就是说，底护板先装配到箱体的框架上，热管理部件再放置于底护板上方，并且热管理部件与底护板之间不固定或采用胶粘的方式固定，从而导致热管理部件与底护板之间的整体刚度不足，在汽车等用电装置的底部受到撞击时，由于热管理部件与底护板之间的刚度不足，可能会对电池造成损坏，从而会影响电池的安全性能。
有鉴于此，本申请实施例提供了一种技术方案，热管理部件和防护板之间通过卡接连接的方式固定，能够提升箱体的整体机械结构性能，同时，热管理部件与防护板之间的卡接，也能起到防底球作用，从而提高了电池的安全性能。

应理解，本申请实施例描述的技术方案不仅仅局限适用于上述所描述的设备，还可以适用于所有使用电池的设备，但为描述简洁，下述实施例均以电动车辆为例进行说明。

为了满足不同的使用电力需求，电池可以包括多个电池单体，其中，多个电池单体之间可以串联或并联或混联，混联是指串联和并联的混合。电池也可以称为电池包。可选地，多个电池单体可以先串联或并联或混联组成电池模块，多个电池模块再串联或并联或混联组成电池。也就是说，多个电池单体可以直接组成电池，也可以先组成电池模块，电池模块再组成电池。
例如，如图2所示，为本申请一个实施例的一种电池100的结构示意图，电池100可以包括多个电池单体20。电池100还可以包括箱体(或称罩体)，箱体内部为中空结构，多个电池单体20容纳于箱体内。如图2所示，箱体可以包括两部分，这里分别称为第一部分101和第二部分102，第一部分101和第二部分102扣合在一起。第一部分101和第二部分102的形状可以根据多个电池单体20组合的形状而定，第一部分101和第二部分102可以均具有一个开口。例如，第一部分101和第二部分102均可以为中空长方体且各自只有一个面为开口面，第一部分101的开口和第二部分102的开口相对设置，并且第一部分101和第二部分102相互扣合形成具有封闭腔室的箱体。多个电池单体20相互并联或串联或混联组合后置于第一部分101和第二部分102扣合后形成的箱体内。
可选地，第一部分101和第二部分102也可以由两部分组成。例 如，第二部分102由底护板16与第二子框架142构成，第一部分101则由顶盖板(图中未示出)和第一子框架141构成，其中，第一子框架141和第二子框架142共同组成框架14，即第一子框架141和第二子框架142可以一体成型。换句话说，电池100的箱体也可以由顶盖板(图中未示出)、框架14以及底护板16共同构成。本申请实施例对箱体的具体构成方式不作限定。
可选地，电池100还可以包括其他结构，在此不再一一赘述。

通常，热管理部件11用于容纳流体以给电池单体20调节温度。这里的流体可以是液体或气体，调节温度是指给电池单体20加热或冷却。在给电池单体20冷却或降温的情况下，该热管理部件11用于容纳冷却流体以给电池单体20降低温度，此时，热管理部件11也可以称为冷却部件、冷却系统或冷却板等。其容纳的流体也可以称为冷却介质或冷却流体，更具体的，可以称为冷却液或冷却气体。另外，热管理部件11也可 以用于加热以给电池单体20升温，本申请实施例对此并不限定。可选的，所述流体可以是循环流动的，以达到更好的温度调节的效果。可选的，流体可以为水、水和乙二醇的混合液或者空气等。
