技术领域
本申请涉及电池领域，尤其是涉及一种储能系统。
背景技术
随着电化学储能技术的发展，储能在电力行业的运用越来越多，例如在风能、光伏等新能源项目因受限于自然环境，在并网时对电网造成的波动较大，通过大规模的储能系统则能够有效解决电网因大幅波动而无法消纳问题。为满足容量需求，储能系统通常体积较大，无论是安装阶段的场地占用还是通过载具远距离运输都存在不小的挑战，故存在改进空间。
发明内容
本申请旨在至少在一定程度上解决相关技术中的技术问题之一。
为此，本申请提出一种储能系统。
根据本申请的储能系统，包括：电池组件；承载框架，所述承载框架的外轮廓构造为集装箱外形并限定有容置空间，用于收容固定所述电池组件，且所述承载框架上形成有安装部；配电装置，适于连接外部负载以向外部负载提供电能；及汇流装置，适于电连接所述电池组件及所述配电装置；所述配电装置和所述汇流装置中的至少一者安装于所述安装部且至少部分位于所述外轮廓内。
储能系统中，所述承载框架的外轮廓构造为集装箱外形，并由承载框架限定出容置空间，电池组件收容固定在容置空间内。同时，所述承载框架上还形成有安装部；所述配电装置和所述汇流装置中的至少一者安装于所述安装部且至少部分位于所述外轮廓内。如此一来，承载框架不仅可作为储能系统的安装框架，收容固定电池组件、汇流装置、配电装置，其构造为集装箱外形，还可直接作为集装箱单元参与运输，使结构件实现层级简化，提高了空间利用率，从而能够提升能量密度。同时，电池组件、配电装置、汇流装置等结构仍保留了较大的设计自由度，在实现外形统一的同时仍能满足产品的个性化设计。

首先需要说明的是，本申请是在上述优先权文件的基础上提出的，因此，对上述优先权文件的术语进行了统一。
优先权文件“202222175392.8”中的“配电装置400”与优先权文件“202222168701.9”中的“配电箱301”为同一零部件，统一命名为“配电装置400”；
优先权文件“202222175392.8”中的“汇流装置300”与优先权文件“202222168701.9”中的“汇流箱302”为同一零部件，统一命名为“汇流装置300”；
优先权文件“202222175392.8”中的“底部托架110”与优先权文件“202222168701.9”中的“底座109”为同一零部件，统一命名为“底部托架110”；
优先权文件“202222175392.8”中的“横梁1202”与优先权文件“202222168701.9”中的“第一横梁108”为同一零部件，统一命名为“横梁1202”；
优先权文件“202222175392.8”中的“纵梁1201”与优先权文件“202222168701.9”中的“第一角柱106”、“第二角柱107”为同一零部件，统一命名为“纵梁1201”。
参图1至图6所示，储能系统1000包括承载框架100、电池组件201、汇流装置300及配电装置400。
该储能系统1000通常可为工、商业储能系统。其包括的电池组件201可根据需求设定。所述承载框架100的外轮廓构造为集装箱外形，且承载框架100限定有容置空间，用于收容固定所述电池组件201。此外，所述承载框架100上形成有安装部1206，用于安装所述汇流装置300及配电装置400中的至少一者。
所述配电装置400适于连接外部负载，以向外部负载提供电能。所述汇流装置300适于电连接所述电池组件201及所述配电装置400。电池组件201通常包含多个电池单元，例如，电池组件201可包括多个电池柜200，多个电池柜200通过所述汇流装置300连接至所述配电装置400，由配电装置400统一分配电力输出。在其他实施方式中，所述电池组件201也可为其他形式，例如可包括一个电池柜200，本实施方式中电池柜200的外形可与前述实施方式中的多个电池柜200构成的整体外形相近或相同，本实施方式中的一个电池柜200内部可包括多个电池模组，该多个电池模组可通过所述汇流装置300汇集连接至所述配电装置400，由配电装置400统一分配电力输出。
所述配电装置400和所述汇流装置300中的至少一者安装于所述安装部1206，相应的，安装于所述安装部1206的所述配电装置400和/或所述汇流装置300至少部分位于所述承载框架100的外轮廓内，尽量保证储能系统1000具有规则的外形。
为明确起见，所述承载框架100的“外轮廓”可以理解为其最外侧边缘围成的立体外形。因考虑电池组件210的安装、承载框架100本身需控制重量等因素，承载框架100通常不会设置成封闭的长方体形箱体(例如标准的集装箱)，而仅根据集装箱的外形设置成基本规则的长方体型框架结构，在此情形下，可将框架结构最外侧的顶点作为其外轮廓的控制点，多个控制点连接形成的长方体外形即可理解为所述承载框架100的“外轮廓”。同时，所述承载框架100的外轮廓理应参照集装箱的一般制造、使用要求，允许合理范围内的误差、公差。
前述储能系统1000中，所述承载框架100的外轮廓构造为集装箱外形，并由承载框架100限定出容置空间，电池组件201收容固定在容置空间内。同时，所述承载框架100上还形成有安装部1206；所述配电装置400和所述汇流装置300中的至少一者安装于所述安装部1206且至少部分位于所述承载框架100的外轮廓内。如此一来，承载框架100不仅可作为储能系统1000的安装框架，收容固定电池组件201、汇流装置300、配电装置400，其构造为集装箱外形，还可直接作为集装箱单元参与运输，使结构件实现层级简化，提高了空间利用率，从而能够提升能量密度。同时，电池组件201、汇 流装置300、配电装置400等结构仍保留了较大的设计自由度，在实现外形统一的同时仍能满足产品的个性化设计，例如，在外形基本相同的情况下，仍能通过调整电池组件201本身的结构、承载框架100的内部构造、承载框架100的结构件的设置等调整储能系统1000的容量、重量、结构强度等，实现产品的差异化。
所述承载框架100的外轮廓构造为集装箱外形，其中，集装箱可为有一定应用规模的非标准集装箱，还可以是标准集装箱。例如，所述集装箱可为具有国际通用标准的集装箱，以便于储能系统的运输流通。以下分别以国际通用的20英尺标准集装箱和40英尺标准集装箱为例进行说明。可以理解的是，只要能够达到方便运输流通的目的，所述承载框架也可以参照国家标准、地区标准、公司标准进行设置，具有一定的通用性和互换性即可。
例如，在一些实施方式中，所述集装箱为20英尺标准集装箱。因20英尺标准台架箱外形尺寸为：长度为6058mm，高度为2591mm(高箱高度为2896mm)，深度为2438mm。因此，如图2所示，所述承载框架100的外轮廓可参照20英尺标准集装箱设置，所述承载框架100的外轮廓具有宽度尺寸W0、深度尺寸D0及高度尺寸H0，W0＝6058mm，D0＝2438mm，H0＝2896mm。相应的，所述电池组件201呈长方体型并具有宽度尺寸W、深度尺寸D及高度尺寸H，并满足：5000mm≤W≤5958mm，2200mm≤D≤2438mm，2191mm≤H≤2746mm。
在另一些实施方式中，所述集装箱还可以为40英尺标准集装箱。同理，40英尺标准集装箱具有固定的外形尺寸：长度为12192mm，高度为2591mm(高箱高度为2896mm)，深度为2438mm。为简化变数，也参图2所示，所述承载框架100的外轮廓可参照40英尺标准集装箱设置，所述承载框架100的外轮廓具有宽度尺寸W0、深度尺寸D0及高度尺寸H0，W0＝12192mm，D0＝2438mm，H0＝2896mm。相应的，所述电池组件201呈长方体型并具有宽度尺寸W、深度尺寸D及高度尺寸H，并满足：11138mmmm≤W≤12096mm，2200mm≤D≤2438mm，2191mm≤H≤2746mm。
电池组件201的外形尺寸小于所述承载框架100的外形尺寸，为承载框架100留出结构设计的空间，同时保证电池组件201在安装至所述承载框架100后，承载框架100可对电池组件201起到防护作用。
参图3、图5及图6所示，在一些实施方式中，所述承载框架100可包括底部托架110和两个端部框架120。
所述底部托架110用于承载所述电池组件201，并限定所述电池组201的两相对侧。所述底部托架110具有相互正交的长度方向、宽度方向及高度方向，底部托架110支撑于所述电池组件201的底部以在所述高度方向对电池组件201进行限位。在具体实施中，所述电池组件201的底部可通过连接件与所述底部托架110连接固定，如此一来，底部托架110可以在水平方向限定所述电池组件201。
所述长度方向、宽度方及高度方向中，高度方向可以理解为竖直方向。通常，储能系统1000在实际应用中，其放置或安装完成后的高度方向即为竖直方向。因此，为方便理解，将储能系统1000在常规使用状态下与竖直方向相同的方向定义为其高度方向，相应的，在水平方向上定义出其长度方向和宽度方向，宽度方向可理解为储能系统1000的深度方向，长度方向可理解为与所述储能系统1000的长度方向一致。
所述两个端部框架120相对设置于所述底部托架110长度方向的两侧，并用于限定所述电池组件201的另外两相对侧。
因底部托架110需要满足承重要求，同时需要控制其对整体空间的占用，在一些实施方式中，所述底部托架110具有高度尺寸B1并满足：150mm≤B1≤400mm。
在一些实施方式中，所述端部框架120可具体包括两纵梁1201及一横梁1202。两纵梁1201沿所述高度方向延伸，并沿所述宽度方向间隔设置于所述底部托架110的两侧，所述纵梁1201的一端与所述底部托架110连接。所述横梁1202连接于所述两纵梁1201的另一端之间。换言之，所述两纵梁1201形成两个立柱，立柱的下端可与所述底部托架110的下端面大致平齐且与所述底部托架110的侧面固定连接，所述横梁1202连接在两个立柱的上端之间，从而形成端部框架120。两个端部框架120夹设于所述电池组件201的相对两侧。
在具体实施中，所述纵梁1201具有沿所述长度方向的尺寸A1并满足：50mm≤A1≤80mm，所述横梁1202沿所述长度方向的尺寸不超出所述纵梁1201的尺寸A1。如此，使得所述端部框架120具有合适的约束强度，同时不过多占用空间。
所述两纵梁1201、所述横梁1202及所述底部托架110围设形成安装空间，且所述安装部1206设于至少一所述纵梁1201的内壁上。所述两纵梁1201、所述横梁1202及所述底部托架110围设于四周，形成一个中部具有所述安装空间的框架，所述配电装置400和所述汇流装置300中的至少一者安装于所述安装部1206并至少部分位于所述安装空间内。

请参阅图15，可选的，若两纵梁1201、横梁1202以及底部托架110构成的空间内设置有配电模块和汇流模块，本申请提供的配电模块和汇流模块可以混合设置在一个箱体中。即储能装置包括配电汇流箱701，配电汇流箱701中包括配电模块和汇流模块。
本申请中，若配电模块和汇流模块位于同一箱体中，配电模块和汇流模块之间的走线位于箱体内部，可以防止配电模块和汇流模块之间的走线被外部环境侵蚀，降低了线路的维护成本，延长了线路的使用寿命。
本申请中，配电汇流箱的尺寸可以根据需求设置。
本申请中，可选的，配电汇流箱701的厚度D3可以小于等于第一角柱的厚度A1。与图3所示实施例相类似的，配电汇流箱701的厚度D3用于指示配电汇流箱701沿底座长度方向的尺寸，第一角柱的厚度A1用于指示第一角柱沿底座的长度方向的尺寸。
图16A、11B和11C是本申请提供的一种配电汇流箱的尺寸示意图。
图16A、11B和11C，示例性的，如图16所示，配电汇流箱的宽度尺寸为W3，厚度尺寸为D3，高度尺寸为H3，其中，1750mm≤W1≤1850mm，100mm≤D1≤300mm,1475mm≤H1≤1775mm。
本申请中，上述示例所提供的配电汇流箱701的尺寸为示例性说明。实际应用过程中，可选的，配电汇流箱701的尺寸可以根据需求设置，具体尺寸的数值本申请不做限定。
在具体实施中，所述配电装置400和所述汇流装置300可以都通过所述安装部1206安装，所述配电装置400和所述汇流装置300可全部位于所述安装空间内。换言之，所述配电装置400和所述汇流装置300均位于所述安装空间内，且所述配电装置400和所述汇流装置300不凸出所述纵梁1201的外端面。如此，使得所述储能系统1000能够保持在承载框架100限定出的集装箱外形之内，便于运输，且能够利用承载框架100对各个装置起到防护作用。参图4所示，所述配电装置400和所述汇流装置300可预装于所述端部框架120内，待储能系统1000完成运输并安装至预定场地后，再将防护盒700安装至所述配电装置400和所述汇流装置300外部。防护盒700安装完成后，其外端面可以高于所述纵梁1201的外端面，因此时已不影响运输。
所述底部托架110可包括两个侧板1101及多个加强板1102，一起构成大致为长方体型的底座。所述两侧板1101可平行设置，并沿所述长度方向延伸。所述多个加强板1102相互间隔设置，且所述加强板1102的两端分别连接于所述两侧板1101的内壁，两个侧板1101及多个加强板1102一起构成大致为长方体型的底座。在具体实施中，所述加强板1102上设有过线孔1103，电池组件201的线缆600可通过加强板1102之间的间隔及所述过线孔1103引出至所述汇流装置300。所述侧板1101、所述加强板1102的底部都可设置折边，方便支撑承载于其上的电池组件201。

可以理解的是，在一些实施方式中，所述电池组件201也可仅包括一个电池柜200，只要所述电池柜200能够填充所述容置空间即可。
在一些实施方式中，所述电池柜200呈长方体型并具有宽度尺寸W1、深度尺寸D1及高度尺寸H1，并满足：1000mm≤W1≤1192mm，单个电池柜深度1100mm≤D1≤1219mm，高度尺寸1850mm≤H1≤2746mm。多个所述电池柜200的宽度方向沿所述电池组件201的长度方向排布。

在具体实施中，所述柜体210的一侧可设有开口。所述电池柜200还包括柜门220，所述柜门220活动连接于所述柜体210上以开启或关闭所述开口。通过设置柜门220，可方便电池柜200的安装、检修维护等操作。
所述温度调节装置240可安装于所述柜门220上。在具体实施中，所述温度调节装置240可为一空调，即电池柜200采用风冷的形式散热，所述温度调节装置240也可以为水冷装置，水冷装置的换热部分也可以设置在所述柜门220上。以下以所述温度调节装置240为一风冷空调为例进行说明。
例如，如图7至图10所示，在一些实施方式中，所述电池柜200中的所述电池单元230为单体电池层，为便于理解，后续单体电池层与所述电池单元230采用同一标号。所述电池柜200包括至少两个单体电池层230，所述至少两个单体电池层230设于所述柜体210内且沿所述高度方向排布，每个所述单体电池层230包括层架，且在所述长度方向和所述高度方向中的每个方向上包括至少一个所述单体电池2302。相邻的两单体电池层230之间形成有风道，用于流通冷却气流。
所述温度调节装置240为风冷装置并包括外循环进风口2401、外循环出风口2402、内循环进风口2403和内循环出风口2404。所述外循环进风口2401和所述外循环出风口2402均适于与外部大气连通，所述内循环进风口2403和所述内循环出风口2404均与所述容纳腔连通。
所述容纳腔内的顶部设导风风道，所述导风风道的一端与所述内循环出风口2404连通，用于引导所述内循环出风口2404吹出的气流流经所述电池单元230。
例如，所述电池柜200还包括设置在所述容纳腔内的顶部的导风件270，所述导风件270与所述柜体配合形成所述导风通道。所述导风通道用于将所述内循环出风口2404吹出的气流引导至所述电池单元230远离柜门220的一侧。换言之，所述温度调节装置240吹入所述柜体210内的冷空气通过顶部的导风件270引导至所述多个电池单元230的后侧，从而由上而下依次进入各单体电池层230之间的风道，冷却单体电池2302。
在一些实施方式中，所述导风通道还用于将所述内循环出风口2404吹出的气流引导至所述电池单元230与所述柜门220相邻的至少一侧。简而言之，导风件270不仅将冷却气流引导至电池单元230的后侧，还同时将冷却气流引导至单体单元230的左右两侧。
所述柜门上设有防爆阀280，防爆阀280开启时可将所述柜体210的内部与外部大气连通。
参图11至图12所示，在另一实施例中，所述电池柜200基本可参前述方式实施，区别仅在于柜体210内的电池单元(即单体电池层)230、温度调节装置240的实施方式不同，且没有前述导风件270。因此，本实施例不再重复相同部分的内容，仅就单体电池层230、温度调节装置240进行阐述。
本实施例中，所述电池柜200包括多个堆叠设置的电池单元230，所述电池单元230包括层架2301和多个单体电池2302，所述层架2301内部形成多个电池收容区。所述多个单体电池2302分别收容于所述电池收容区。所述层架2301内形成有液冷通道，所述液冷通道用于流通冷却介质以冷却所述单体电池2302。相应的，所述温度调节装置240可为液冷装置的换热组件，所述层架2301上设有进出水管2304，层架2301内部的液冷通道通过所述进出水管2304与所述换热组件连通，以通过液冷方案冷却所述单体电池2302。
例如，在一些实施方式中，所述层架2301可包括托盘2311和多个隔板2312。所述托盘2311的一端开放，即托盘2311构成一侧具有开口的壳体。所述多个隔板2312设置于所述托盘2311内并将所述托盘2311的内部分隔为所述多个电池收容区。所述托盘2311和至少部分隔板2312内部形成有所述液冷通道。在具体实施中，所述进出水管2304可设置在所述托盘2311上，一部分隔板2312或者所有隔板2312的内部设置液冷通道，隔板2312与电池收容区内的单体电池2302接触，可同时实现约束定位和液冷散热。
