近些年，新能源汽车有了飞跃式的发展，在电动汽车领域，动力电池作为电动汽车的动力源，起着不可替代的重要作用。电池由箱体和容纳于箱体的容纳空间内的多个电池单体组成。其中，电池作为新能源汽车核心零部件不论在使用性能、使用寿命和安全性方面等均有着较高的要求。
发明人发现，在电池后期使用的过程中由于环境比较复杂，电池的箱体容易出现水蒸气进入的现象，以造成电池的箱体内的环境湿度较高，当电池的箱体内的水蒸气达到一定浓度或与箱体的内壁存在温差时，常常出现水蒸气液化的现象，产生大量的冷凝液，由于聚集在电池的箱体内的冷凝液会对箱体内的各电子元器件的性能和各电子元器件之间的绝缘带来不利影响，从而极容易导致电池在后期使用过程中出现各电子元器件损坏或各电子元器件之间绝缘失效的现象，进而导致电池在使用过程中存在较大的安全隐患，且不利于电池的使用寿命。在现有技术中，通常采用在电池的箱体内设置干燥剂或者吸湿片等方法，或者在电池的箱体内设置冷凝器，使得箱体内的气体中的水蒸气遇到冷凝器后会产生液化现象并生成冷凝液，以降低电池的箱体内的环境湿度。然而，采用这种结构的电池的除湿效果不佳，且同样会造成冷凝液在箱体内堆积的现象，从而导致电池依旧存在较大的使用安全隐患，且不利于电池的长期使用。
基于上述考虑，为了解决电池在后期使用过程中存在较大的安全隐患以及使用寿命较短的问题，发明人经过深入研究，设计了一种电池除湿系统，电池除湿系统设置有通气管、抽气机构和冷却机构，通气管用于与电池的箱体相连，以使通气管与箱体形成供气体流动的循环回路，抽气机构用于抽取箱体内的气体，以使其它在循环回 路内流动，冷却机构用于冷却流经通气管的冷凝段的气体。
在具有这种电池除湿系统的电池中，通过抽气机构能够抽取箱体内的气体，以实现箱体内的气体在箱体和通气管之间循环流动，并通过冷却机构对通气管的冷凝段进行冷却，使得气体在流经冷凝段时遇冷会产生冷凝液化的现象，以将气体中的水蒸气冷凝成冷凝液，依次循环，从而有利于降低箱体内的环境湿度，以解决电池的箱体内的各电子元器件在后期使用过程中因环境湿度过大而出现损坏或绝缘失效的现象，进而有利于降低电池在使用过程中存在的安全隐患。
此外，通过这种结构的电池除湿系统在对气体进行冷凝后产生的冷凝液聚集在通气管的冷凝段内，从而能够有效地将气体冷凝生产后的冷凝液与电池分离，以减少冷凝液在电池的箱体内聚集的现象，进而有利于提高电池的使用安全性，且有利于提高电池的使用寿命。
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装置中。可以使用具备本申请公开的电池除湿系统、电池等组成该用电装置的电源系统，这样，有利于缓解电池的各电子元器件出现损坏或绝缘失效的现象，以提升电池的使用安全性和使用寿命。

根据本申请的一些实施例，参照图2，并请进一步参照图3，图3为本申请一些实施例提供的电池除湿系统30的结构示意图。本申请提供了一种电池除湿系统30，电池除湿系统30包括通气管31、抽气机构32和冷却机构33。通气管31的两端均用于与箱体10连通，通气管31具有冷凝段311。抽气机构32用于抽取箱体10内的气体，以使气体在箱体10和通气管31之间循环流动。冷却机构33用于冷却流经冷凝段311的气体，以使气体在冷凝段311内冷凝。
其中，通气管31的两端均用于与箱体10连通，即通气管31的两端均与箱体10内的容纳空间连通，使得气体能够在箱体10与通气管31之间形成循环回路。冷却机构33用于冷却流经冷凝段311的气体，以使气体在冷凝段311内冷凝，即冷却机构33用于对通气管31的冷凝段311进行降温，从而使得气体在流经冷凝段311时会碰到温度较低的冷凝段311的内壁，以使气体发生冷凝液化的现象。
在通过抽气机构32对箱体10内的气体进行抽取时能够实现气体在箱体10和通气管31之间循环流动，并通过冷却机构33对通气管31的冷凝段311进行冷却，使得气体在流经冷凝段311时遇冷会产生冷凝液化的现象，以将气体中的水蒸气冷凝成冷凝液，依次循环，进而有利于降低箱体10内的环境湿度，以解决电池100的箱体10内的各电子元器件在后期使用过程中因环境湿度过大而出现损坏或绝缘失效的现象，有利于降低电池100在使用过程中存在的安全隐患。此外，通过这种结构的电池除湿系统30在对气体进行冷凝后产生的冷凝液聚集在通气管31的冷凝段311内，从而能够有效地将气体冷凝生产后的冷凝液与电池100分离，以减少冷凝液在电池100的箱体10内聚集的现象，进而有利于提高电池100的使用安全性，且有利于提高电池100的使用寿命。
根据本申请的一些实施例，参照图3，并请进一步参照图4和图5，图4为本申请一些实施例提供的冷却机构33的结构示意图，图5为本申请一些实施例提供的冷却机构33的剖视图。冷却机构33包括冷却箱331，冷却箱331的内部形成用于容纳第一冷却介质的容纳腔3311，冷凝段311位于容纳腔3311内。冷却机构33的具体结构可参见相关技术，在此不再赘述。
其中，冷却箱331开设有入口3312和出口3313，入口3312和出口3313均与容纳腔3311连通，入口3312和出口3313分别用于供第一冷却介质流入或流出，以实现第一冷却介质在容纳腔3311内进行循环流动，从而通过第一冷却介质能够对位于容纳腔3311内的冷凝段311进行冷却。
示例性的，第一冷却介质可以为二氟一氯甲烷、氨气或氟利昂等。
通过在冷却箱331内开设用于容纳第一冷却介质的容纳腔3311，且将通气管31的冷凝段311设置于冷却箱331的容纳腔3311内，从而能够提高冷却机构33对冷凝段311的冷却效果，以增强流经冷凝段311的气体的冷凝能力。
根据本申请的一些实施例，请参见图4和图5所示，冷凝段311在容纳腔3311内呈S型延伸。
其中，冷凝段311呈S型延伸，即冷凝段311为S型弯曲结构(蛇形结构)。
需要说明的是，在一些实施例中，冷凝段311的结构也可以为直管结构或Z型结构等。
通过将冷凝段311设置为S型结构，从而能够有效延长气体在冷凝段311内的流动行程，使得气体流经冷凝段311的时长被极大地延长，进而有利于提高气体在流经冷凝段311时的冷凝效果，以提升电池除湿系统30的对电池100的箱体10内的气体的除湿能力。
根据本申请的一些实施例，请继续参见图3所示，通气管31还包括出气段312和进气段313。出气段312的一端用于与箱体10连通，出气段312的另一端与冷凝段311连通，出气段312用于将箱体10内的气体导向冷凝段311内。进气段313的一端与冷凝段311连通，进气段313的另一端用于与箱体10连通，进气段313用于将冷凝段311内的气体导向箱体10内，抽气机构32设置于进气段313上。
其中，进气段313用于将冷凝段311内的气体导向箱体10内，也就是说，流经进气段313的气体为流经冷凝段311进行冷凝后的气体。
示例性的，抽气机构32可以为轴流电机或抽气泵等。
需要说明的是，在其他实施例中，抽气机构32也可以设置于出气段312上。
通过将抽气机构32设置于进气段313上，以使经过抽气机构32的气体已经流经冷凝过，从而能够降低湿度较大的气体对抽气机构32造成的损坏，进而有利于延长抽气机构32的使用寿命。
根据本申请的一些实施例，请参见图3、图4和图5所示，电池除湿系统30还包括集液器34。集液器34连接于冷凝段311，集液器34用于收集气体在冷凝段311内冷凝生成的冷凝液。
通过在冷凝段311上连接集液器34，以使集液器34能够对气体在冷凝段311内冷凝生产的冷凝液进行回收，从而能够有效缓解冷凝段311内的冷凝液堆积过多，以降低冷凝段311被冷凝液堵塞的风险，进而有利于保证电池除湿系统30的正常运行。
可选地，集液器34的结构可以是多种，比如，集液器34可以为设置于冷凝段311内的干燥包等。
在一些实施例中，集液器34包括集液箱341和集液管342。集液箱341用于收集冷凝液，集液管342连通集液箱341和冷凝段311，集液管342用于将冷凝液导向集液箱341内。
集液箱341通过集液管342与冷凝段311连通，以使集液管342能够将冷凝段311内的冷凝液导向至集液箱341内，从而便于对气体在冷凝段311内冷凝生产的冷凝 液进行收集，采用这种结构的集液器34结构简单，便于实现，且能够有效提高集液器34对冷凝液的回收能力和存储能力。
根据本申请的一些实施例，请参见图5所示，冷却机构33包括冷却箱331，冷却箱331的内部形成用于容纳第一冷却介质的容纳腔3311。冷凝段311包括依次相连且位于容纳腔3311内的多个U型部3111，每个U型部3111的底部形成有用于与集液管342连通的出液口3112。
其中，由于设置于容纳腔3311内的冷凝段311为S型结构，因此，冷凝段311具有依次连接的多个U型部3111，且每个U型部3111的底部均与集液管342连通。
通过将每个U型部3111的底部均开设有与集液管342相连通的出液口3112，使得集液管342能够对每个U型部3111内冷凝形成的冷凝液进行收集，从而便于集液器34对冷凝段311内的冷凝液进行回收，且有利于提高冷凝液的回收效率。
根据本申请的一些实施例，请继续参见图5所示，集液器34还包括干燥单元343。干燥单元343设置于集液箱341内，干燥单元343用于吸收冷凝液。

示例性的，干燥单元343为干燥包。
通过在集液箱341内设置干燥单元343，以通过干燥单元343能够对集液箱341内的回收的冷凝液进行吸收，从而有利于提高集液器34对冷凝液回收能力。
根据本申请的一些实施例，请参见图3、图4和图5所示，电池除湿系统30还包括冷却管35。冷却管35具有第一冷却段351和第二冷却段352，第一冷却段351用于设置于箱体10内，冷却管35用于供第二冷却介质流动，以调节箱体10内的温度。冷却机构33用于冷却流经第二冷却段352的第二冷却介质。
其中，冷却管35内的第二冷却介质能够在第一冷却段351和第二冷却段352之间循环流动，第二冷却段352设置于冷却机构33的冷却箱331的容纳腔3311内，第二冷却介质在流经第二冷却段352时能够经过冷却机构33冷却后再流动至第一冷却段351内，以使第二冷却介质能够在箱体10内进行热交换，从而对箱体10内的温度起到调节作用。
示例性的，第二冷却介质可以为水或乙二醇混合剂等。
通过将冷却管35的第一冷却段351设置于电池100的箱体10内，且通过冷却机构33能够对冷却管35的第二冷却段352进行冷却，以使第二冷却介质在冷却管35内进行循环流动时能够对箱体10内的温度进行调节，从而使得电池除湿系统30还能够实现电池100的箱体10内的温度调节功能，这种结构的电池除湿系统30将通气管31和冷却管35共用一个冷却机构33，有利于降低电池除湿系统30的制造成本，且有利于节省能源。

通过将通气管31的进气端314和出气端315分别连接于箱体10在第一方向上的两侧，以使进气端314和出气端315位于箱体10在第一方向上的两侧，从而便于气体在箱体10和通气管31之间循环流动，且通过这种结构能够有效减少箱体10内的气体出现局部流动的现象。
进一步地，进气端314和出气端315在第二方向上间隔布置，第二方向垂直于第一方向。
通过将位于箱体10第一方向上的两侧的进气端314和出气端315沿第二方向间隔布置，从而有利于增强箱体10内的气体的整体流动性，进而能够提高箱体10内的除湿效果。
