温度的调节可以包括对电池单体20加热或者冷却。例如，在给电池单体20冷却或降温的情况下，温度调节装置30可以向电池单体20输出流体， 以给电池单体20降低温度。此时，温度调节装置30也可以称为冷却部件、冷却系统或冷却板等，其输出的流体也可以称为冷却介质或冷却流体或工质。更具体地，可以称为冷却液或冷却气体。冷却介质具体可以采用诸如水、水和乙二醇的混合液等。

根据不同的电力需求，电池单体20的数量可以设置为任意数值。多个电池单体20可通过串联、并联或混联的方式连接以实现较大的容量或功率。由于每个电池10中包括的电池单体20的数量可能较多，为了便于安装，可以将电池单体20分组设置，每组电池单体20组成电池模块。电池模块中包括的电池单体20的数量不限，可以根据需求设置。
如图2所示，为本申请一个实施例的一种电池单体20的结构示意图，电池单体20包括一个或多个电极组件22、壳体211和盖板212。壳体211和盖板212形成外壳或电池盒21。壳体211的壁以及盖板212均称为电池单体20的壁。壳体211根据一个或多个电极组件22组合后的形状而定，例如，壳体211可以为中空的长方体或正方体或圆柱体，且壳体211的其中一个面具有开口以便一个或多个电极组件22可以放置于壳体211内。例如，当壳体211为中空的长方体或正方体时，壳体211的其中一个平面为开口面，即该平面不具有壁体而使得壳体211内外相通。当壳体211可以为中空的圆柱体时，壳体211的端面为开口面，即该端面不具有壁体而使得壳体211内外相通。盖板212覆盖开口并且与壳体211连接，以形成放置电极组件22的封闭的腔体。壳体211内填充有电解质，例如电解液。
该电池单体20还可以包括两个电极端子214，两个电极端子214可以设置在盖板212上。盖板212通常是平板形状，两个电极端子214固定在盖板212的平板面上，两个电极端子214分别为正电极端子214a和负电极端子214b。每个电极端子214各对应设置一个连接构件23，或者也可以称为集流构件23，其位于盖板212与电极组件22之间，用于将电极组件22和电极端子214实现电连接。
如图2所示，每个电极组件22具有第一极耳221a和第二极耳222a。 第一极耳221a和第二极耳222a的极性相反。例如，当第一极耳221a为正极极耳时，第二极耳222a为负极极耳。一个或多个电极组件22的第一极耳221a通过一个连接构件23与一个电极端子连接，一个或多个电极组件22的第二极耳212a通过另一个连接构件23与另一个电极端子连接。例如，正电极端子214a通过一个连接构件23与正极极耳连接，负电极端子214b通过另一个连接构件23与负极极耳连接。
在该电池单体20中，根据实际使用需求，电极组件22可设置为单个，或多个，如图2所示，电池单体20内设置有4个独立的电极组件22。
电池单体20上还可设置泄压机构213。泄压机构213用于电池单体20的内部压力或温度达到阈值时致动以泄放内部压力或温度。
本申请实施例，通过在电池10中设置与电池单体20相互依附的温度调节装置30，当电池10进入异常状态或即将进入时能够制动温度调节装置30工作，即温度调节装置30能够向电池单体20输出流体，输出的流体用于调节电池单体20的温度。如此，能够有效地降低电池10发生异常或即将发生异常后导致的不良影响，比如能够有效降低电池10发生热失控后所导致的热扩散的可能性。
在一些实施例中，电池10还可以包括容纳腔，电池单体20和温度调节装置30均设置在容纳腔中。其中，温度调节装置30设置在容纳腔中未设置有电池单体20的区域中。
可选地，温度调节装置30与电池单体20之间可以接触设置，也可以不接触设置。
该技术方案，将温度调节装置30设置在电气腔中未设置有电池单体20的区域中，这样，在电池单体20出现异常状态或即将出现异常状态时，能够降低处于异常状态或即将处于异常状态的电池单体20对温度调节装置30的不良影响。比如，能够降低发生热失控的电池单体20产生的高温高压气体对温度调节装置30的影响。
在一些实施例中，温度调节装置30可以用于接收控制信息，该控制信息用于控制温度调节装置30向电池单体20输出流体。
作为一种示例，电池10可以包括电池管理系统(battery management system，BMS)，BMS可以监测电池单体20的电池状态参数，若BMS基于监测到的电池单体20的电池状态参数确定电池10处于异常状态或即将处于 异常状态时，则可以向温度调节装置30发送控制信息。
可选地，温度调节装置30可通过有线或无线方式与BMS进行通信交互。有线通信方式例如可以包括制器局域网(control area network，CAN)通信方式、菊花链(daisy chain)通信方式。无线通信方式例如可以包括蓝牙通信、无线保真(wireless fidelity，WIFI)通信、ZigBee通信等各种方式，在此并不限定。
如图3所示，BMS可以包括监测单元和控制单元。其中，监测单元用于实时监测电池单体20的电池状态参数，并将监测到的电池状态参数反馈给控制单元。控制单元接收到电池状态参数后，判断电池单体20是否处于异常状态或是否即将处于异常状态。若判断电池单体20处于异常状态或即将处于异常状态，则控制单元控制温度调节装置30进行响应。例如，向温度调节装置30发送控制信息。温度调节装置30接收到控制信息后，向电池单体20输出流体，最终使电池10达到一个稳定、可控的状态。
或者，如图4所示，BMS可以包括控制单元。当电池单体20出现异常状态或即将处于异常状态时，电池单体20的电池状态参数可以触发控制单元，以使控制单元控制温度调节装置30进行响应。例如，向温度调节装置30发送控制信息。温度调节装置30接收到控制信息后，向电池单体20输出流体，最终让电池10达到一个稳定、可控的状态。
作为另一种示例，该控制信息可以包括电池单体20的电池状态参数。例如，如图5所示，在电池单体20出现异常状态或即将出现异常状态的情况下，电池单体20的电池状态参数可以直接制动温度调节装置30进行响应，以使温度调节装置30及时向电池单体20输出流体。
该技术方案，控制信息包括电池单体20的电池状态参数，即电池单体20的电池状态参数直接制动温度调节装置30响应工作。如此，减少了温度调节装置30与其他部件之间进行信息交互所花费的时间，从而极大地降低了对电池单体20的温度进行调节的耗时，提高了调节效率，使得电池10能够在较短的时间内达到正常、温度并可控的状态。
可选地，如图6和图7所示，在本申请实施例中，温度调节装置30可以包括排气构件310和安全构件，安全构件用于在电池状态参数达到阈值的情况下输出流体，流体经由排气构件310进入电池10内部，以调节电池单体20的温度。
该技术方案，通过设置安全构件，使得在电池单体20出现异常状态或即将出现异常状态时，安全构件能够及时向电池单体20输出流体，并且通过设置排气构件310，安全构件输出的流体能够快速通过排气构件310到达电池10的内部，实现了在电池单体20出现异常状况或即将出现异常状态时及时有效地对电池单体20进行温度调节的目的。
排气构件310可以包括排气孔，排气孔的形状例如可以为圆形、梯形、矩形或不规则形状等等。
如图8和图9所示，电池10还可以包括密封件320，该密封件320覆盖排气构件310，被配置为在电池状态参数达到阈值的情况下被破坏，以使流体经由排气孔到达电池10的内部。具体而言，当电池状态参数达到阈值的情况下，电池单体20产生的高温高压气体可以破坏密封件320，从而使得流体经由排气孔到达电池10的内部。
上述技术方案，电池10还包括用于覆盖排气构件310的密封件320，如此，能够提高电池10处于正常状态时电池10的气密性。进一步地，密封件320被配置为在电池单体20处于异常状态或即将处于异常状态时被破坏，使得安全构件输出的流体能够及时到达电池10的内部，以调节电池单体20的温度，从而提高调节电池单体20温度的效率。
密封件320可以包括薄膜。可选地，该薄膜可以为耐温薄膜，例如可以耐受100℃甚至更高温度。示例性地，该薄膜可以包括但不限于聚甲基乙撑碳酸酯(poly propylene carbonate，PPC)塑料。
将密封件320设置为包括薄膜，由于薄膜相对来说体积和质量均较小，进而能够有效提高电池10的质量能量密度和体积能量密度。
在流体为液体的情况下，电池10还可以包括排出孔，以使温度调节装置30输出的液体通过该排出孔从电池10内部排出。如此，能够降低电池10内部残留的液体对电池10的影响，如造成电池10的短路等。
进一步地，电池10还可以包括支撑构件330，该支撑构件330包括流道，流道的入口与安全构件连接，用于在安全构件输出流体后容纳流体。其中，排气构件310可以设置在支撑构件330的表面，排气构件310与流道的出口连接，以使流体流入排气构件310。
该技术方案，通过设置包括流道的支撑构件330，且流道的入口与安全构件连接，出口与排气构件310连接，这样，在安全构件输出流体后，流 体能够容纳在流道中，使得安全构件输出的流体可以被充分地利用，降低了流体被浪费的概率，从而能够迅速调节电池单体20的温度。
作为一种示例，支撑构件330可以包括电池10的横梁331和/或纵梁332。例如，如图7所示，支撑构件330包括横梁331和纵梁332。其中，横梁331和/或纵梁332的内部可以设置有流道。该内部流道可以为全通结构，即所有流道互相连接。
可选地，横梁331的所有部分均可以设置有流道，或者，部分横梁331的内部可以设置有流道。类似地，纵梁332的所有部分均可以设置有流道，或者，部分纵梁332的内部可以设置有流道。
具体而言，当电池单体20出现热失控或即将出现热失控时，热失控所产生的高温破坏排气孔表面的薄膜，然后安全构件所输出的流体可以通过横梁331和/或纵梁332的流道，经由横梁331表面的排气孔和/或纵梁332表面的排气孔到达电池10内部，从而达到降温的目的，降低了电池10进一步发生热扩散的可能性。
该技术方案，将支撑构件330设置为电池10的横梁331和/或纵梁332，即复用电池10原有的结构件，一方面，降低了电池10的生产成本；另一方面，减少了支撑构件330对电池10空间的占用率，能够有效减小电池10的尺寸。
在一些可能的实施例中，再次参考图6和图7，安全构件可以包括工质制造组件340和通断组件350，该工质制造组件340与流道的入口连接，通断组件350与工质制造组件340的第一端连接。其中，在电池状态参数未达到阈值的情况下，通断组件350处于断开组件；在电池状态参数达到阈值的情况下，通断组件350处于闭合状态，以使工质制造组件通过流道的入口将流体输入流道。
上述技术方案，安全构件包括通断组件350和输出流体的工质制造组件340，并且在电池单体20处于正常状态的情况下通断组件350处于断开状态，使得电池10能够正常带载供电，在电池单体20处于异常状态或即将处于异常状态的情况下通断组件350处于闭合状态，这样，安全构件能够接入电池单体20所在的回路，实现了工质制造组件340通过入口将流体输入流道的目的。
其中，工质制造组件为用于产生或准备流体的装置。可选地，工 质制造组件340可以包括但不限于水泵、蒸发器或压缩机等。
通断组件350指的是能够控制电路中电流是否流通的电子元件。比如在需要时打开电路(允许电流通过)，在不需要时关闭电路(阻止电流通过)。可选地，通断组件350可以为开关，如晶体管、场效应晶体管(field effect transistor，FET)、绝缘栅双极型晶体管(insulated gate bipolar transistor，IGBT)等，或者，通断组件350也可以为继电器或接触器等。
BMS可以控制通断组件350进行关断或者闭合。比如，在BMS监测到电池单体20的电池状态参数未达到阈值的情况下，可以控制通断组件350处于断开状态；在BMS监测到电池单体20的电池状态参数达到阈值的情况下，控制通断组件350处于闭合状态。或者，在电池单体20的电池状态参数达到阈值的情况下，高温高压气体可以使得通断组件350从断开状态转换为闭合状态。
比如，在电池状态参数未达到阈值的情况下，即整车处于正常使用状态的情况下，通断组件350处于断开状态，电池10正常带载供电。当电池10出现或即将出现异常状态时，比如发生了热失控，BMS控制通断组件350从断开状态转换为闭合状态且常规继电器断开，温度调节装置30接入电池回路中，电池10进行放电，且工质制造组件340向电池单体20输出流体。
需要说明的是，在通断组件350处于闭合状态，即温度调节装置30接入电池回路的情况下，电池10内部可以一直进行低功率自放电。如此，可以缓慢降低电池10的电量，从而使得电池10逐渐处于一个低电量状态，以便后续处理。
通常情况下，流体总体的量是固定的。因此，为了合理使用流体，进一步地，安全构件还可以包括调流组件360，该调流组件360的一端连接于工质制造组件340的第二端，用于在工质制造组件340输出流体的过程中，调节流体的流速。
可以看出，工质制造组件340包括三个端口，分别为第一端、第二端以及用于输出流体的出口，其中，该出口与流道的入口连接。
上述技术方案，将安全构件设置为包括用于调节流体的流速的调流组件360，在需要较多流体的情况下，可以通过调流组件360将流体的流速设置的较快，而在需要较少流体的情况下，则可以通过调流组件360将流体的流速设置的慢一点，进而有效实现了流体的灵活输出。
可选地，调流组件360可以包括电阻。例如，调流组件360可以为可调电阻。
在调流组件360为可调电阻的情况下，如图10所示，可调电阻的一端与工质制造组件340连接，另一端与电池回路串联连接。其中，可调电阻用于通过调节电池回路的电压来调节工质制造组件的输出功率，进而调节流体的流速。
具体而言，在可调电阻串联进电池回路中后，可以对电池回路进行分压。可调电阻的电阻值的不同，使得电池回路的电压也随之不同。流体的流速与工质制造组件340的输出功率相关，功率又与电压相关，电池回路的电压不同使得工质制造组件340的输出功率也不同。输出功率越大，流体的流速越大；相反，输出功率越小，流体的流速也就越小，从而实现了调节流体的流速的目的。
由于流体的速率与工质制造组件的输出功率相关，功率又与电压相关。该技术方案，将调流组件360设置为包括可调电阻，并且通过调节电池回路的电压来调节工质制造组件340的输出功率，从而实现调节流体流速的目的。一方面，成本较低，容易实现，并且效率较高。另一方面，可调电阻的设置可以对电池回路进行分压，降低了电池单体20失效后，电池10的电压施加在失效的电池单体20两端，从而造成不良影响的概率。
在本申请实施例中，若温度调节装置30基于接收到的电量向电池单体20输出流体，在温度调节装置30接收到的电量满足第一功率的情况下，若温度调节装置30接收的电量为放电装置释放的，则温度调节装置30可以断开与放电装置的连接。其中，第一功率为温度调节装置30输出流体所需的功率。
放电装置例如可以为电池10或者可以为前文提到的除电池10之外的其他电池。
或者，当放电装置为电池10时，考虑到电池10通常情况下为满电状态，而第一功率通常比较小。例如，用于温度调节装置30输出流体的电量可能只占电池电量的1％，即电池10还剩99％的电量，这99％的电量可能还会使电池10出现异常状况。
因此，在温度调节装置30接收的电量满足第一功率的情况下，温度调节装置30还可以用于继续接收电量。例如，直至电池10的剩余电量小 于或等于电量预设值。其中，在温度调节装置30接收的电量满足第一功率的情况下，温度调节装置30不向电池单体20输出流体。
换言之，温度调节装置30仅接收电量但不工作。
可选地，电量预设值可以使得电池10在当前时刻以及之后均处于安全状态。
上述技术方案，在温度调节装置30接收的电量满足温度调节装置30输出流体的功率的情况下，温度调节装置30继续接收电量。这样，若温度调节装置30接收的电量为电池10释放的电量，那么电池10的电量可以缓慢降低，即可以实现电池10的长时间自放电，进而可以将处于异常状态或即将处于异常状态的电池10的电量降至安全区间，降低了发生进一步的恶化事件。
电池10除了可以包括上述内容提到的装置之外，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。再次参考图1，箱体可以包括两部分，这里分别称为第一部分111和第二部分112，第一部分111和第二部分112扣合在一起。第一部分111和第二部分112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111和第二部分112可以均具有一个开口。例如，第一部分111和第二部分112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111的开口和第二部分112的开口相对设置，并且第一部分111和第二部分112相互扣合形成具有封闭腔室的箱体。其中，箱体可以包括底板112a、侧板112b和梁。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111和第二部分112扣合后形成的箱体内。
应理解，在不冲突的前提下，本申请描述的各个实施例和/或各个实施例中的技术特征可以任意的相互组合，组合之后得到的技术方案也应落入本申请的保护范围。
