Description

一种用于储能装置的箱体及储能装置、储能系统
本申请要求于2023年03月08日提交中国国家知识产权局、申请号为202310268425.X、申请名称为“一种用于储能装置的箱体及储能装置、储能系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电化学储能领域，具体设计一种用于储能装置的箱体及储能装置、储能系统。
背景技术
建设电化学储能电站通常需要集中布置大量的电化学储能装置，现有的储能装置为了方便运输和集中布置通常采用集箱体作为载体。
现有的一部分储能装置的箱体采用单层空间，电池模块、温控模块等电气组件以及换热组件都布置于同一空间。相应的，储能装置的箱体内部的热量过多，不利于储能装置的散热和整体效率。另外，箱体需要设置多个散热或连通窗口，不利于防尘、防水等安全防护。电池模块可装容量较少的问题。
现有的一部分储能装置将换热组件安装于箱体外部，换热组件安装于箱体外部的储能装置的体积大于标准集装箱。然而，储能系统通常需要集中布置大量储能装置，从而导致储能装置的箱体的相邻排列或上下层叠需要占用更大的空间或土地面积，从而降低储能系统的储能密度，并且增加储能系统的建设成本，不利于电化学储能产业的大规模推广。
发明内容
本申请提供了一种用于储能装置的箱体及储能装置、储能系统，通过凹陷型开放式的第一容纳区放置储能装置的外置组件，可以提高储能装置的散热能力和安全防护能力，而且可以提高储能系统的储能密度且降低建设成本。
第一方面，本申请提供一种用于储能装置的箱体。箱体包括四个立柱、三个侧板、隔板、底板和密封门。隔板与底板沿箱体的高度方向相对设置，两个侧板沿箱体的长度方向相对设置，另一个侧板与密封门沿箱体的宽度方向相对设置，沿箱体的高度方向每个立柱的高度大于隔板的高度。其中，三个侧板、隔板及底板经四个立柱固定并与密封门围合形成闭合式的第二容纳区，四个立柱及隔板相围合形成开放式的第一容纳区。第一容纳区和所述第二容纳区沿箱体的高度方向层叠排列。两个所述侧板。沿箱体的长度方向第一容纳区或第二容纳区的长度等于沿箱体的长度方向相对设置的两个侧板之间的距离，沿箱体的高度方向隔板与底板之间的距离小于每个立柱的高度。
本申请提供的箱体包括上下分层设置的开放式的第一容纳区和闭合式的第二容纳区，可以降低开放式的第一容纳区内组件的热量对闭合式的第二容纳区内组件的影响， 从而提高储能装置的散热效率。另外，本申请提供的箱体通过降低隔板的高度形成凹陷型开放式的第一容纳区用于容纳储能装置的外置组件，相对于现有储能装置的箱体，不仅便于储能装置的外置组件的放置还可以保证箱体整体尺寸的标准化，有利于减少箱体的层叠所需的空间或相邻排列所需的占地面积，从而增加储能系统的储能密度且降低建设成本。
一种实现方式中，第二容纳区包括第一容纳腔和第二容纳腔，沿箱体的长度方向第一容纳腔和第二容纳腔相邻排列，沿箱体的高度方向第一容纳腔高度或第二容纳腔的高度中至少一个等于第二容纳区的高度。
本申请提供的箱体中第二容纳区仅仅设置纵向相邻排列的第一容纳腔和第二容纳腔，相对于现有的储能装置的箱体中利用通道或间隙区分多个空间的方式，不仅可以更充分地利用第二容纳区的空间，而且有利于分腔进行布置、维护工作从而减少工作时间。例如，第一容纳腔用于放置电池模块，第二容纳腔可用于放置功率模块和温控模块。相应的，对第一容纳腔中电池模块的布置或维护工作和对第二容纳腔中功率模块和温控模块的布置或维护工作可以互不影响且同时开展，从而提高储能装置的布置和维护效率。
一种实现方式中，第一容纳腔的体积大于第二容纳腔的体积。其中，沿箱体的长度方向第一容纳腔的长度大于第二容纳腔的长度，沿箱体的长度方向第一容纳腔的长度与第二容纳腔的长度之和等于第二容纳区的长度。
本申请提供的箱体中第二容纳区仅仅设置纵向相邻排列的第一容纳腔和第二容纳腔，相对于现有的储能装置的箱体中利用通道或间隙区分多个空间的方式，不仅可以更充分地利用第二容纳区的空间，而且有利于分腔进行布置、维护工作从而减少工作时间。例如，第一容纳腔用于放置电池模块，第二容纳腔可用于放置功率模块和温控模块。相应的，对第一容纳腔中电池模块的布置或维护工作和对第二容纳腔中功率模块和温控模块的布置或维护工作可以互不影响且同时开展，从而提高储能装置的布置和维护效率。
一种实现方式中，第二容纳区包括多个电池架，沿箱体的长度方向多个电池架依次相邻排列，多个电池架中任意相邻的两个电池架沿箱体长度方向的间距相同，多个电池架沿箱体长度方向的第一个或最后一个电池架用于区隔第一容纳腔和第二容纳腔。其中，第一个或最后一个电池架与其相邻侧板的间距等于相邻的两个电池架的间距。每个电池架的进深可为1700～2200mm。
本申请提供的箱体中利用多个电池架区隔第一容纳腔和第二容纳腔，相对于现有的储能箱体中使用隔离墙或间隙区隔多个空间，可以更充分地利用第二容纳区域的空间，从而提高箱体内可以容纳的电池数量。另外，利用电池架区隔第一容纳腔和第二容纳腔，还可以在第二容纳腔中布置电池。例如，第一容纳腔用于放置电池，第二容纳腔可用于放置功率模块和温控模块。功率模块和温控模块只占用第二容纳腔一部分时，第二容纳腔的其它部分也可以用于布置电池。相应的，相对于现有的储能装置的箱体，本申请提供的箱体可以容纳更多的电池。
一种实现方式中，密封门包括至少两个，至少两个密封门沿箱体的长度方向排列。其中，至少两个密封门中一个密封门用于闭合第二容纳腔，至少两个密封门中其他密 封门用于闭合第一容纳腔。

一种实现方式中，箱体与标准集装箱的长度、宽度和高度相同。标准集装箱有多种规范，箱体可以是任意规范的标准集装箱。例如，箱体的长度为6058mm，箱体的宽度为2438mm，箱体的高度为2438～4150mm。本申请提供的箱体与标准集装箱体的尺寸相同，不仅便于储能装置的运输，并且有利于多个箱体的层叠或相邻排列。
一种实现方式中，每个立柱的高度等于标准集装箱的高度。本申请提供的箱体中立柱的高度等于标准集装箱的高度且隔板的高度低于立柱的高度从而形成凹陷型的第一容纳区，即使第一容纳区放置外置组件也不会导致储能装置的整体高度超过标准集装箱的高度，从而保证储能装置的体积的标准化，有利于减少储能装置的层叠所需的空间或相邻排列所需的占地面积，从而增加储能系统的储能密度且降低建设成本。

本申请的储能装置利用开放式的第一容纳区放置尺寸相对较小的换热组件、并利用闭合式的第二容纳区放置电气组件，从而降低了换热组件的热量对电气组件的影响，从而提高了储能装置的散热性能。另外，本申请提供的储能装置将电气组件放置于闭合式的第二容纳区域，可以减少箱体的连通或维护窗口，从而提高储能装置的安全防护能力。并且，本申请提供的储能装置通过设置凹陷型的开放式第一容纳区放置换热组件，不仅便于换热组件的外置而且可以保证储能装置整体尺寸的标准化，有利于减少多个储能装置的层叠所需的空间或相邻排列所需的占地面积，从而增加储能系统的储能密度且降低建设成本。
一种实现方式中，电气组件包括多列电池模块，每列电池模块包括多个电池模块，每列电池模块中多个电池模块沿箱体的高度方向层叠排列于第一容纳腔。

本申请提供的储能装置通过设置凹陷型的开放式第一容纳区放置换热组件，不仅便于换热组件的外置，而且可以保证换热组件不露出于储能装置外侧或上侧，有利于减少多个储能装置的层叠所需的空间或相邻排列所需的占地面积，从而增加储能系统的储能密度且降低建设成本。
第三方面，本申请提供一种储能系统。储能系统包括多个如第二方面及第二方面中上述实现方式中任一项的储能装置，每个储能装置的换热组件包括出风口和进风口。其中，换热组件的出风口和进风口朝向储能装置的箱体高度方向，多个储能装置沿储能装置的箱体长度或宽度方向相邻排列，相邻两个储能装置的箱体之间的间隙小于换热组件的长度、高度或宽度。或，换热组件的出风口和进风口朝向储能装置的箱体宽度或长度方向，多个储能装置沿储能装置的箱体高度方向层叠排列，相邻两个储能装置的箱体之间的间隙小于换热组件的长度、高度或宽度。
本申请提供的储能系统中多个储能装置采用凹陷型的开放式第一容纳区放置换热组件，可以保证换热组件不露出于储能装置外侧或上侧，从而减少层叠或相邻排列的两个多个储能装置所需的间隙，从而减少储能系统所需的空间或所需的占地面积，从而增加储能系统的储能密度且降低建设成本。
一种实现方式中，换热组件包括壳体和换热板，壳体用于容纳换热板。其中，进风口设于壳体沿储能装置的箱体长度或宽度方向的侧部，换热板与隔板倾斜设置。或，进风口设于壳体沿储能装置的箱体高度方向的顶部，换热板与隔板平行设置。
本申请提供的储能系统中多个储能装置的换热组件可以可灵活地根据层叠或相邻布置的需求设置换热组件的进风口和出风口的位置，从而更方便储能装置的并箱组装。并且，本申请提供的储能系统中多个储能装置的换热组件可以相应地设置换热板与隔板的相对位置，从而提高单个储能装置以及整个储能系统的散热能力。
一种实现方式中，换热器为液冷换热器，液冷换热器与电池模块的液冷管道连接。液冷相对风冷可在放置电池模块的第二容纳区内实现无风道设计，节省空间可容纳更 多电池，大幅减少系统非电芯度电成本。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“上述”、“该”和“这一”旨在也包括例如“一个或多个”这种表达形式，除非其上下文中明确地有相反指示。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
其中，本申请各实现方式中描述或限定的长、宽、高等数据以及垂直、平行、等于、大于或小于等情况，均应理解为符合工程测量误差范围内的数值或情况。
工商业储能场景和电站储能场景的储能系统中储能装置通常包括箱体、电池模块和换热组件。现有储能装置的箱体一般仅包括单个容纳空间。换热组件设于箱体的内部，则会造成箱体内部的发热增加且需要在箱体开设连通窗口，从而影响储能装置的散热性能和安全防护能力。换热组件设于箱体的外部，则会增加单个储能装置的占地面积且造成各个储能装置的整体尺寸不统一，不利于多个储能装置的集中布置。
为解决上述问题，本申请实施例提供一种用于储能装置的箱体和储能装置、储能系统，通过凹陷型开放式的第一容纳区放置储能装置的外置组件，可以提高储能装置的散热能力和安全防护能力，而且可以提高储能系统的储能密度且降低建设成本。
本申请实施例提供的储能装置包括箱体10、电气组件和换热组件30。其中，电气组件包括多个电池模块20、功率模块40和温控模块50。电池模块20用于充电或放电。换热组件30用于为储能装置散热。功率模块40用于利用外部电源对电池模块20充电或接收电池模块20的放电向负载供电。温度模块50用于根据储能装置的发热情况控制换热组件30对储能模块散热。
图1为本申请实施例提供的箱体的一种示意图。如图1所示，箱体10包括底板11、三个侧板12、密封门13、隔板14和四个立柱132。其中，隔板14与底板11沿箱体10的高度方向相对设置。两个侧板12沿箱体10的长度方向相对设置，另一个侧板12与密封门13沿箱体10的宽度方向相对设置。
本申请实施例中，四个立柱132及隔板14相围合形成开放式的第一容纳区01，三个侧板12、隔板14及底板11经四个立柱132固定并与密封门13围合形成闭合式的第二容纳区02。第一容纳区01和第二容纳区02沿箱体10的高度方向层叠排列。
本申请实施例中，沿箱体10的长度方向第一容纳区01或第二容纳区02的长度等于沿箱体10的长度方向相对设置的两个侧板12之间的距离，沿箱体10的高度方向隔板14与底板11之间的距离小于每个立柱132的高度。
本申请实施例中，沿箱体10的高度方向每个立柱132的高度大于隔板14的高度。沿箱体10的高度方向每个立柱132的高度大于第一容纳区01的高度或第二容纳区02的高度。或者，沿箱体10的高度方向每个立柱132的高度大于第一容纳区01的高度和第二容纳区02的高度之和。
本申请实施例中，第一容纳区01用于放置换热组件30，第二容纳区02用于放置电气组件。
本申请实施例提供的箱体10包括上下分层设置的开放式的第一容纳区01和闭合式的第二容纳区02，可以降低开放式的第一容纳区01中外置组件的热量对闭合式的第二容纳区02的影响，从而提高储能装置的散热效率。另外，本申请提供的箱体10通过降低隔板14的高度形成凹陷型开放式的第一容纳区01用于容纳储能装置的外置组件，相对于现有储能装置的箱体，不仅便于储能装置的外置组件的放置还可以保证储能装置整体尺寸的标准化，有利于减少箱体的层叠所需的空间或相邻排列所需的占地面积，从而增加储能系统的储能密度且降低建设成本。
如图1所示，第二容纳区02包括第一容纳腔021和第二容纳腔022，沿箱体10 的长度方向第一容纳腔021和第二容纳腔022相邻排列，沿箱体10的高度方向第一容纳腔021的高度或第二容纳腔022的高度中至少一个等于第二容纳区02的高度。
如图1所示，沿箱体10的长度方向第一容纳腔021的长度大于第二容纳腔的长度22，沿箱体10的长度方向第一容纳腔021的长度与第二容纳腔022的长度之和等于第二容纳区02的长度。
本申请提供的箱体10中第二容纳区02仅仅设置纵向相邻排列的第一容纳腔021和第二容纳腔022，相对于现有的储能装置的箱体中利用通道或间隙区分多个空间的方式，不仅可以更充分地利用第二容纳区02的空间，而且有利于分腔进行布置、维护工作从而减少工作时间。例如，第一容纳腔021用于放置电池模块，第二容纳腔022可用于放置功率模块40和温控模块50。相应的，对第一容纳腔中电池模块20的布置或维护工作和对第二容纳腔中功率模块40和温控模块50的布置或维护工作可以互不影响且同时开展，从而提高储能装置的布置和维护效率。
如图1所示，箱体10包括多个电池架15，多个电池架15沿箱体10的长度方向依次间隔排列，多个电池架15中任意相邻的两个电池架15沿箱体10长度方向的间距相同，多个电池架15沿箱体10长度方向的第一个或最后一个电池架15用于区隔第一容纳腔021和第二容纳腔022。本申请实施例中，第一容纳区01用于放置电池模块20，第二容纳区02用于放置功率模块40和温控模块50。
本申请提供的箱体10利用电池架15区隔第一容纳腔021和第二容纳腔022，相对于现有的储能箱体中使用隔离墙或间隙区隔多个空间，可以更充分地利用第二容纳区域02的空间，从而提高箱体10可以容纳的电池模块的数量。另外，利用电池架15区隔第一容纳腔021和第二容纳腔022，还可以在第二容纳腔022中布置电池模块20。例如，第一容纳腔021用于放置电池模块20，第二容纳腔022可用于放置功率模块40和温控模块50。功率模块40和温控模块50只占用第二容纳腔022一部分时，第二容纳腔022的其它部分也可以用于布置电池模块20。相应的，相对于现有的储能装置的箱体，本申请提供的箱体可以容纳更多的电池模块20。
一种实施例中，箱体10包括多个间隔柱131，多个间隔柱131用于支撑隔板14及放置于隔板14的外置组件。多个间隔柱131沿箱体10的长度方向依次间隔排列，多个间隔柱131分别固定于底板11与隔板14之间。每个间隔柱131与一个电池架15相对应，每个间隔柱131与一个电池架15沿箱体10的宽度方向的投影相重叠。示例性的，隔板14用于放置储能装置的换热组件30。本申请提供的箱体通过设置与多个电池架15分别对应的多个间隔柱131，不仅可以提高箱体10的稳固性，且不占用第二容纳区02的空间。
一种实施例中，箱体10包括一个密封门13，一个密封门13用于闭合第一容纳腔021和第二容纳腔022。本申请提供的箱体10中密封门13用于闭合第一容纳腔021和第二容纳腔022，同时设置开放式的第一容纳区01用于放置外置组件，对外置组件的维护工作不会影响被密封门13闭合的第一容纳腔021和第二容纳腔022内的组件，从而可以提高储能装置的维护便利性和安全防护能力。
一种实施例中，箱体10包括多个密封门13。示例性的，箱体10包括至少两个密封门13，至少两个密封门13沿箱体10的长度方向排列。其中，至少两个密封门13 中一个密封门13用于闭合第二容纳腔022，至少两个密封门13中其他密封门13用于闭合第一容纳腔021。
本申请提供的箱体10中第一容纳腔021和第二容纳腔022分别设置纵向开启的密封门13，第一容纳腔021和第二容纳腔022可以分开布置或维护，仅开启第一容纳腔021密封门13或第二容纳腔022的密封门13不会影响另一容纳腔放置的组件，从而可以提高储能装置的维护便利性和安全防护能力。
本申请实施例中，箱体10和标准集装箱的长度、宽度和高度相同。每个立柱132的高度等于标准集装箱的高度。可以理解的是，标准集装箱包括多种规格，每种规格的标准集箱具有特定的长宽高尺寸。本申请实施例中，箱体10的长宽高尺寸对应其中一种标准集装箱的长宽高尺寸规格。例如，箱体10的长宽高尺寸可以是20尺标准集装箱、40尺标准集装箱、20尺高柜或40尺高柜中的一种。示例性的，箱体的长度为6058mm，箱体的宽度为2438mm，箱体的高度为2438～4150mm。本申请提供的箱体10与标准集装箱体的尺寸相同，不仅便于储能装置的运输，并且有利于多个箱体的层叠或相邻排列。
本申请实施例中，每个立柱132的高度等于标准集装箱的高度。本申请提供的箱体10中立柱132的高度等于标准集装箱的高度且隔板14的高度低于立柱132的高度从而形成凹陷型的第一容纳区01，即使第一容纳区01放置外置组件也不会导致储能装置的整体高度超过标准集装箱的高度，从而保证储能装置的体积的标准化，有利于减少储能装置的层叠所需的空间或相邻排列所需的占地面积，从而增加储能系统的储能密度且降低建设成本。
本申请实施例中，箱体10包括一个或多个加强梁133，每个加强梁133与箱体10的长度或宽度方向相平行，每个加强梁133用于固定连接两个立柱132，沿箱体10的高度方向每个加强梁133设置于隔板14的上方。本申请提供的箱体通过设置与箱体宽度或长度方向平行的加强梁，不仅有利于提高箱体的整体结构强度，还可以利用加强梁防护第一容纳区域内放置的组件，如换热组件。
图2为本申请实施例提供的箱体的另一种示意图。如图2所示，与箱体10的宽度方向相平行的加强梁133也可以称为第一加强梁134，与箱体10的长度方向相平行的加强梁133也可以称为第二加强梁135。
如图2所示，沿箱体10的长度方向的两个立柱132通过第二加强梁135固定连接。示例性的，第二加强梁135固定连接第一侧板121和第三侧板123的同侧立柱132。具体的，第一加强梁134与第二加强梁135相互垂直排列，第一加强梁134和第二加强梁135分别与隔板14平行排列。在箱体10的高度z方向，第一加强梁134与第二加强梁135的高度高于隔板14。相应的，四个立柱132、第一加强梁134、第二加强梁135与隔板14可在隔板14的顶部形成长方形、凹陷型、开放式的第一容纳区01。
本申请实施例提供的箱体10通过设置第一加强梁134或第二加强梁135中的至少一个，不仅可以提高箱体10的结构强度和结构稳定性，另外还可以用于防护第一容纳区01放置的外置组件，如换热组件30。
结合图1和图2，第一容纳区01可为开放式容纳区，其形状可为U型结构或方形框架结构。换热组件可放置在第一容纳区01，以与电池模块分层设置。这样，可减少 换热组件30的占地面积，提高第二容置区02内的电池模块的填充空间，进而提高储能装置的容量。
以上对第一容纳区01的结构做了解释说明，以下将对第二容纳区02的结构做解释说明。本申请实施例中，第二容纳区02为底板11、立柱132、侧板12、隔板14以及密封门13形成封闭式容纳区。第二容纳区02用于放置电池模块20、功率模块40和温控模块50等电气组件。
其中，第二容纳区02包括第一容纳腔021和第二容纳腔022，沿箱体10的长度方向第一容纳腔021和第二容纳腔022相邻排列，沿箱体10的高度方向第一容纳腔021的高度和第二容纳腔022的高度等于第二容纳区02的高度。
参照图2，第二容纳区02可划分为第一容纳腔021和第二容纳腔022。沿箱体10的长度x方向，第一容纳腔021和第二容纳腔022相邻排列。第一容纳腔021用于放置电池模块20。第二容纳腔022用于放置功率模块40和温控模块50。
一种实施例中，在箱体10的长度x方向，第一容纳腔021和第二容纳腔022之间可用挡板分隔。挡板上设置通孔，以用于穿设功率模块40和电池模块20之间的线缆。
继续参照图2，第一容纳腔021内可设置多个电池架15。沿箱体10的长度方向，多个电池架15依次相邻排列。每个电池架15可包括多个导轨，在放置电池模块20时，可将电池模块分别沿对应的导轨放置两个相邻的电池架15上。其中，电池模块20的进深为1700～2200mm。
