在本申请的描述中需要说明的是除非另有明确的规定和限定术语“安装”、“相连”、“连接”、“附接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
本申请中出现的“多个”指的是两个以上(包括两个)。
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：圆柱电池 单体、方形电池单体和软包电池单体。
本申请的实施例所提到的供电装置也称电池，是指包括至少一个电源部以提供更高的电压和容量的单一的物理模块，每个电源部具有一个或多个电池单体。例如，本申请中所提到的电池可以包括电池模块或电池包等。电池一般包括用于封装一个或多个电池单体的箱体，箱体可以避免液体或其他异物影响电池单体的充电或放电。
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。

供电装置还包括温度采集模块和电池管理系统，温度采集模块用于采集电源部的温度信息，以供电池管理系统进行检测，当电池管理系统检测到电源部的温度信号超出正常范围时，会限制供电装置的输出功率以实现安全防护。
相关技术中，一种常见的采集电源部的温度信息的方式为：将温度采集模块从汇流部件的背离电源部的一侧抵接于汇流部件，以获取电源部的温度信息。但是，由于温度采集模块占用了汇流部件的背离电源部的一侧的空间，导致供电装置内部结构松散，降低供电装置的能量密度。
发明人经研究发现，如果利用电源部和汇流部件之间的空间来安装温度采集模块，将能够避免占用汇流部件的背离电源部的一侧的空间，提高供电装置的结构紧凑性，使其具有较好的能量密度。进一步地，考虑到电源部和汇流部件之间的空间有限，组装难度较高，将温度采集模块设计为不可拆卸的结构，也能够避免在装配温度采集模块的过程中温度采集模块解体，从而简化供电装置的组装过程。
基于上述思路，本申请的发明人提出了一种技术方案，温度采集模块为不可拆卸的结构，不仅组装简单，且结构紧凑，具有较高的能量密度。
可以理解的是，本申请实施例描述的供电装置可以直接对用电装置供电，也可以通过并联、串联或混联的方式形成供电装置，以供电装置的形式对各种用电装置供电。

本申请的实施例描述的电池单体、电源部以及供电装置不仅仅局限适用于上述所描述的用电装置，还可以适用于所有使用电池单体、电源部以及供电装置的用电装置，但为描述简洁，下述实施例均以电动汽车为例进行说明。

绝缘护板60可以为常见的塑料绝缘板，绝缘护板60用于绝缘保护电池单体10的表面的同时暴露出测温表面111的部分区域，以供温度采集单元36进行温度采样。绝缘护板60通过其他的定位结构与电池单体10进行相对位置的固定，本申请实施例不进行展开描述。
第一端部312和第二端部313分别通过定位孔319和凸起61的配合来与绝缘护板60进行固定。
如图4和图5所示，以第一端部312为例，第一端部312具有沿第一方向Z贯穿的定位孔319，绝缘护板60的背离电池单体10的表面的一侧凸出形成凸起61，凸起61与定位孔319的形状匹配，凸起61插入定位孔319，以在XY平面上限制绝缘护板60和支架31的相对位置，进而限制温度采集模块30在箱体内的位置。

本申请的一些实施例提出一种用电装置，包括供电装置100，供电装置100用于提供电能。
由于本申请的一些实施例的供电装置100中，温度采集模块30为不可拆卸的形式，供电 装置100在组装过程中其温度采集模块30不易解体，从而具有较好的组装便易性，因此本申请的一些实施例的用电装置也具有其供电装置100组装方便的优点。
如图1至图10所示，本申请的一些实施例提出一种供电装置100，包括箱体70、多个电池单体10、多个汇流部件20、温度采集模块30、信号处理部40、信号采集部50和绝缘护板60，电池单体10、汇流部件20、温度采集模块30、信号处理部40、信号采集部50和绝缘护板60均设置于箱体70的内部。相邻的两个电池单体10的电极端子通过一个汇流部件20连接，以实现实现该两个电池单体10的并联或串联。电池单体10和汇流部件20之间具有安装空间，温度采集模块30包括支架31、保护部32、温度采集单元36导热胶和绝缘件35，支架31包括主体部311以及位于主体部311的两侧的第一端部312和第二端部313，第一端部312和第二端部313分别插入相邻的两个汇流部件20与电池单体10之间的空间，且其端部分别抵接于对应的电极端子的外周面。支架31与保护部32一体成型，保护部32具有放置腔324，温度传感部33位于放置腔324的内部，保护部32具有导热开口321、插接部322和开口部323，导热开口321面向电池单体10设置，通过增强部34封闭导热开口321且将温度传感部33与电池单体10的表面导热连接，开口部323背离电池单体10且使用绝缘件35封闭，插接部322位于侧部，被配置为供信号采集部50插入。信号采集部50的一端插入插接部322以与温度传感部33连接，信号采集部50的另一端与信号处理部40连接，以输出温度传感部33所采集到的代表温度信号的电信号。
在电池单体10、绝缘护板60、汇流部件20以及信号处理部40组装完成后，只需要将支架31的第一端部312和第二端部313分别插入相邻的两个汇流部件20与对应的电池单体10之间的空间，使第一端部312和第二端部313与对应的电极端子抵接，支架31的主体部311抵压住信号处理部40，温度采集模块30的导热胶抵接于电池单体10的表面，再将信号采集部50插入温度采集模块30以与温度采集单元36连接，以完成供电装置100的组装。由于支架31和保护部32一体成型，温度传感部33不可拆卸地布置于保护部32内部，使得整个温度采集模块30为一体式结构，一方面，在供电装置100组装过程中，温度采集模块30不易解体，简化了供电装置100组装过程，另一方面，由于利用了汇流部件20和电池单体10之间的空间来固定温度采集模块30，能够避免过多占用汇流部件20背离电池单体10一侧的空间，从而使供电装置100结构紧凑，具有较好的能量密度。
需要说明的是，在不冲突的情况下，本申请中的实施例中的特征可以相互结合。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
