Description

电池架和包括该电池架的电力存储装置
技术领域
本公开涉及一种电池架和一种包括该电池架的能量存储***。
本申请要求2019年6月5日在韩国提交的韩国专利申请10-2019-0066645号的优先权，其公开内容通过引用被并入本文中。
背景技术
高度适用于各种产品并表现出诸如高能量密度等优异电气性能的二次电池不仅普遍地被用于便携式装置，而且还被用于由电源驱动的电动车辆(EV)或混合动力电动车辆(HEV)。由于二次电池能够大大减少化石燃料的使用，并且在能量消耗期间不产生任何副产品，因此作为用于增强环境友好性和能量效率的新能源，二次电池受到关注。
目前广泛使用的二次电池包括锂离子电池、锂聚合物电池、镍镉电池、镍氢电池、镍锌电池等。单元二次电池单体、即单元电池单体的工作电压为大约2.5V到4.5V。因此，如果要求更高的输出电压，则可以将多个电池单体串联连接以构造电池组。另外，根据电池组要求的充电/放电容量，可以将多个电池单体并联连接以构造电池组。因此，可以根据要求的输出电压或需要的充电/放电容量来不同地设定电池组中所包括的电池单体的数目。
同时，当多个电池单体被串联或并联连接以构造电池组时，通常首先构造包括至少一个电池单体的电池模块，然后通过使用至少一个电池模块并添加其它部件来构造电池组。这里，根据各种电压和容量要求，能量存储***可以被构造成包括电池架，每个电池架具有至少一个电池组，所述至少一个电池组包括至少一个电池模块。
在传统的电池架的情况下，当在架壳体中的所述多个电池模块中的至少一个电池模块中发生异常情况时，在发生该异常情况的电池模块中可能发生着火。
当在电池模块中的任一个电池模块中发生着火时，如果火焰和热量传播到相邻电池架的周围电池模块，则这可能引起另外的着火，从而导致严重的财产损失或严重的人身伤害。
因此，需要一种方法来提供一种电池架和一种包括该电池架的电力存储装置，当至少一个电池模块着火时，该电池架能够防止火焰和热量传播到相邻的电池模块。
发明内容

具体实施方式
通过参考附图详细描述本公开的实施例，本公开将变得更加显而易见。应当理解，本文中所公开的实施例仅是示意性的以更好地理解本公开，并且可以以各种方式修改本公开。另外，为了容易理解本公开，附图未按实际比例绘制，而是一些部件的尺寸可能被夸大。
图1是用于示出根据本公开实施例的能量存储***的图，图2是用于示出图1的能量存储***的控制操作的图，图3是示出图2的电池架的截面视图，图4是示出图3的电池架的主要部分的放大视图。
参考图1到图4，所述能量存储***1用作能量源，并且可以用于家庭或工业用途。所述能量存储***1可以包括电池架10以及用于容纳所述电池架10的架容器50。
可以设置一个电池架10或多个电池架10。在下文中，在该实施例中，将描述多个电池架10被设置成沿着水平方向(即，左右方向)并排地堆叠的情形。
多个电池架10中的每个电池架可以包括电池模块100、架壳体200和防火墙300。
所述电池模块100可以被设置成多个。多个电池模块100可以在竖直方向上彼此堆叠。多个电池模块100中的每个电池模块可以包括一个或多个电池单体110。
所述电池单体110是二次电池，并且可以是袋型二次电池、方形二次电池和圆柱形二次电池中的至少一种。在下文中，在该实施例中，所述电池单体110将被描述为袋型二次电池。
所述架壳体200可以容纳多个电池模块100。为此，所述架壳体200可以具有用于容纳多个电池模块100的容纳空间。
所述防火墙300用于在发生火情时防止火焰和热量朝向相邻的电池架10的侧表面传播，并且可以被设置到所述架壳体200的两个侧表面中的至少一个侧表面。
可以设置至少一个防火墙300或多个防火墙300。在下文中，在该实施例中，将描述多个防火墙300被分别设置在电池架10的架壳体200之间的情形。即，多个防火墙300可以沿着左右方向被分别置放在多个电池架10之间。
多个防火墙300可以被设置成能够沿着竖直方向覆盖多个电池模块100的所有侧表面的板形，并且可以被固定到多个电池模块100和架壳体200。具体地，多个防火墙300可以借助于紧固构件S通过拧紧到架壳体200和多个电池模块100而被固定。
在下文中，将更详细地描述多个防火墙300的紧固和固定结构。
多个防火墙300中的每个防火墙可以包括壳体联接部310和模块联接部330。
所述壳体联接部310用于与所述架壳体200联接，并且可以被设置成多个。多个壳体联接部310可以被置放成沿着至少一个防火墙300的竖直方向以预定距离彼此间隔开。多个壳体联接部310可以通过由紧固构件S来拧紧而被固定到架壳体200。
所述模块联接部330用于与多个电池模块100联接，并且可以被设置成多个。多个模块联接部330可以以预定距离与壳体联接部310间隔开，并且可以被置放成沿着至少一个防火墙300的竖直方向以预定距离彼此间隔开。多个模块联接部330可以通过由紧固构件S拧紧而被固定到电池模块100。
借助于所述模块联接部330和壳体联接部310，所述电池模块100可以被更稳定地固定在架壳体200内。即，通过所述壳体联接部310和模块联接部330，所述电池模块100甚至在电池架10的侧表面处也被固定到架壳体200，从而更可靠地确保被容纳在所述架壳体200中的电池模块100的结构稳定性。
因此，在该实施例中，借助于所述防火墙300，增加了被容纳在所述电池架10的架壳体200中的电池模块100的结构稳定性，也可以进一步增强振动或抗震性能。
图5是用于示出当发生火情时、在图1的能量存储***的电池架之间的防止火焰传递和热量吸收的视图。
参考图5，由于能量存储***1的电池架10中的任一个电池架中的任一个电池模块100等中的异常情况，可能发生着火。
此时，如果火焰和热量从已经发生着火的电池架10传播到相邻的电池架10，则这可能引起另外的着火，从而导致严重的财产损失或严重的人身伤害。
在该实施例中，当发生诸如着火这样的火情时，通过置放在所述电池架10之间的防火墙300，防止火焰和热量朝向相邻的电池架10传播，从而有效地防止火焰和热量传播到相邻的电池架10。
图6是用于示出根据图1的能量存储***的电池架的另一实施例的防火墙的视图，图7是用于示出图6的防火墙的主要部分的视图。
由于根据该实施例的防火墙305类似于先前实施例的防火墙300，因此将不再描述与先前实施例大致相同或类似的构造，在下文中，将详细描述与先前实施例不同的构造。
参考图6和图7，所述防火墙305可以包括入口端口351、出口端口353和冷却通道355。
所述入口端口351和出口端口353可以连通外部冷却***(未示出)和稍后说明的冷却通道355。所述冷却通道355用于冷却多个电池模块100，并且与入口端口351和出口端口353连通，并且可以使得从外部冷却***供应的冷却水在防火墙305的内部循环。
如上所述，在该实施例中，由于在所述防火墙305的内部设置有连接到外部冷却***以使冷却水循环的冷却通道355，所以当在电池模块100中发生诸如着火的异常情况时，能够更快速地吸收从电池模块100产生的热量，并且更有效地防止火焰朝向相邻的电池架10传播。
根据如上所述的各种实施例，能够提供一种电池架10和一种包括该电池架10的能量存储***1，当至少一个电池模块100着火时，该电池架10能够防止火焰和热量朝向相邻的电池架10的电池模块100传播。
尽管已经示出并描述了本公开的实施例，但是应当理解，本公开不限于所描述的具体实施例，并且本领域技术人员能够在本公开的范围内做出各种修改和变型，并且不应从本公开的技术思想和观点单独地理解这些变型。
