随着新能源技术的不断发展,各种与储能有关的技术也在不断的升级;其中,以集装箱作为储能方式的储能集装箱得到了广泛应用。储能集装箱包括箱体以及容纳在箱体中的储能模块(例如电池簇、电池、电池单体等)、液冷设备、消防设备、配电模块、信号及供电模块箱等多种模块设备,考虑到储能集装箱的运输,箱体一般采用标准尺寸的集装箱,因此,标准尺寸的储能集装箱受到尺寸限制,如何合理布局储能集装箱内部的空间显得尤为关键。
相关技术中,箱体中用于容纳储能模块的空间,和用于容纳其他模块的空间一般呈交叉分部;例如液冷设备和消防设备集成在用于容纳储能模块的空间中,由于多种模块设备等集成在同一个空间内,因此在同一个空间内的线路、管路等排布将影响空间的使用,因此此时箱体内的空间利用率较低,对储能密度也将产生影响,同时也不利于对多种模块设备的单独维护;或者,液冷设备、消防设备等其他多种模块设备分别位于用于容纳储能单元的空间的相对两端侧,此时,在储能集装箱的数量为多个的情况下,多个储能集装箱无法相邻靠排布,否则会影响对多种模块设备的维护作业,因此,多个储能集装箱的占地面积更大,单位面积的储能密度也会降低。
基于以上考虑,为了解决储能集装箱内部布局合理性的问题,设计了一种储能集装箱,通过将电气仓和液冷机组设置在电池仓沿第一方向上的同一侧,即电气仓和液冷机组与电池仓相分离且独立设置,能够有效提高集装箱的空间利用率,并且在对多个储能集装箱进行排布时,还可以将相邻两储能集装箱的电池仓一侧相抵靠放置,能够降低多个储能集装箱排布的占地空间,以提高单位面积的储能密度。
请参考图1、图2和图5,第一方面,本申请实施例提供了一种储能集装箱100,包括箱体10,箱体10的内部设置有电池仓20、电气仓30和液冷机组40;电气仓30和液冷机组40设于电池仓20在第一方向O上的同一端侧。
箱体10为储能集装箱100的集装箱本体结构,箱体10为标准尺寸的集装箱尺寸;箱体10内部形成空腔,以供于电池仓20、电气仓30、液冷机组40等其他模块设备在箱体10内进行布设。
应理解的,箱体10作为集装箱可以为长方体结构,为了便于描述,本申请实施例基于长方体的集装箱定义三个方向,其中,可以定义箱体10的长度方向为第一方向O,可以定义箱体10的宽度方向为第二方向P,可以定义箱体10的高度方向为第三方向Q。由此,本申请实施例中,电气仓30和液冷机组40设于电池仓20在第一方向O上的同一侧,即电气仓30和液冷机组40可以布设在电池仓20在箱体10的长度方向上的同一侧。
电池仓20用于容置储能模块,例如是电池单体、或者是包括由电池单体形成的电池,或者是由电池串联形成的电池簇等。以电池簇为例,电池仓20内可以容置一簇或多簇的电池簇,在具有多簇的电池簇的情况下,电池簇在电池仓20内沿第一方向O形成排布。
可选地,电池仓20可以通过隔板、安装梁、支架等结构在箱体10内搭设形成,利用隔板、安装梁、支架等结构搭建出呈独立空间的电池仓20,以供于电池簇等的排布设置。
电气仓30用于容置电气设备,例如,电气仓30内可以容纳包括但不限于配电箱、总控箱、消防控制模块、消防管路、风机等;可选地,电气仓30可以通过隔板、安装梁、支架等结构在箱体10内搭设形成,利用隔板、安装梁、支架等结构搭建出呈独立空间的电气仓30,以供于电气设备等的排布设置。
液冷机组40是用于向电池仓20内提供循环冷却液的冷却设备;液冷机组40可以直接容置在箱体10的内部,并邻靠于电池仓20设置;或者,还可以利用隔板、安装梁、支架等结构在箱体10内搭建出呈独立空间的液冷仓,以供于液冷机组40的容置。其中,液冷机组40可以为使用冷却水、冷却油、制冷剂等冷却介质的机组;可选地,液冷机组40可以选用水冷机组,以供于使用冷却水进行冷却。
其中,电气仓30和液冷机组40设于电池仓20在第一方向O上的同一端侧,可选地,电气仓30的仓门和液冷机组40的操作端面均可以位于箱体10的端部,并外露于箱体10,由此,操作人员可以在箱体10外的同一侧对电气仓30和液冷机组40进行操作维护。
本申请实施例提供的储能集装箱100,通过将电气仓30和液冷机组40设置于电池仓20在第一方向O上的同一端侧,能够有效提高集装箱的空间利用率;同时,工作人员可以在储能集装箱100的同一端侧对电气仓30、液冷机组40进行排查,有效地提高了现场维护的便捷性;且在对储能集装箱100进行安装配置时,电气仓30和液冷机组40位于同一侧的布局方式也能够提高装配的便捷性,在对多个储能集装箱100进行排布时,还可以将相邻两储能集装箱100的电池仓20一侧相抵靠放置,能够降低多个储能集装箱100排布的占地空间,以提高单位面积的储能密度;由此,本申请实施例提供的储能集装箱100,电气仓30和液冷机组40位于电池仓20同一侧的布局方式更具有合理性。
请参考图1、图2和图5,在一些实施例中,电气仓30和液冷机组40沿第二方向P排布,第二方向P与第一方向O相垂直。
可以理解地,第一方向O可以为箱体10的长度方向,由此,第二方向P可以为箱体10的宽度方向。
其中,电气仓30和液冷机组40位于电池仓20在第一方向O上的同一侧,即电气仓30和液冷机组40在箱体10长度方向上的一端侧。
在此基础上,电气仓30和液冷机组40还在第二方向P上形成排布,即电气仓30和液冷机组40在箱体10的宽度方向上形成排布,由此,电气仓30和液冷机组40位于箱体10长度方向上的一端侧,且电气仓30和液冷机组40在箱体10的端侧并沿箱体10的宽度方向依次排布。由此,工作人员可以在箱体10的端部同时对电气仓30和液冷机组40进行维护检修,有效地提升了维护的便捷性。
可选地,电气仓30在第一方向O上并朝向箱体10的外部一侧形成有仓门,在电气仓30的仓门上可以安装消防控制模块或者其他模块的控制按钮、显示面板等,以充分利用电气仓30内的空间,提高电气仓30的空间利用率,进而降低整个电气仓30占比箱体10的比重,从而使得电池仓20能够占比箱体10的比重更大,以实现提高储能密度的目的。
请参考图3至图5,在一些实施例中,还包括电池簇50和主控箱60,电池簇50沿第一方向O排布于电池仓20内,电池簇50在第三方向Q上的一侧设置有主控箱60,电池簇50电性连接于主控箱60;其中,第一方向O、第二方向P和第三方向Q均相垂直。
电池簇50是指在一定条件下,将多个电池或电池单体组合成一个群体共同工作而形成一个电池系统。电池簇50可以通过电池或电池单体之间的互相协作,提高整个系统的可靠性、稳定性和寿命。采用电池簇50的设计,相比于无簇设计,能够提高系统一致性,减少电池单体之间的连接结构,从而能够提高整体的放电量。
电池簇50的簇数可以为一簇或一簇以上的任意多簇,在电池簇50的簇数为多个的情况下,多簇电池簇50可以沿第一方向O,也就是箱体10的长度方向依次排布在电池仓20内。

如此设置,电池簇50内的至少两个电池51可以沿第三方向Q依次排布,从而在多个电池簇50沿第一方向O排布的情况下,电池51的排布方式合理利用了电池仓20内的空间,能够提高电池仓20内的空间利用率,进而能够提高储能集装箱100的储能密度。

如此布设,相比于需要间隔排布两个储能集装箱100的方式,因电气仓30和液冷机组40位于电池仓20的同一端侧的结构设计,能够使得两个储能集装箱100能够相靠拢且排列成一排,有效地降低了两个储能集装箱100的占地面积总和,因此能够提高占地的单位面积能量密度;同时,由于两个储能集装箱100的电气仓30和液冷机组40均位于端部,不会影响维护操作,还能够提升现场操作的便利程度,即只需在箱体10的同一侧对两个储能集装箱100的电池仓20进行操作。
请参考图1和图8,在一些实施例中,集装箱组1100的数量为两组,两组集装箱组1100沿第二方向P依次排列,两组集装箱组1100呈镜像分布;其中,第二方向P与第一方向O相垂直,第一方向O为箱体10的长度方向,第二方向P为箱体10的宽度方向。
可以理解地,上述的储能集装箱100的箱体10的宽度方向可以与第二方向P相平行,同时,储能集装箱100的箱体10的长度方向可以与第一方向O相平行,储能集装箱100的箱体10的高度方向可以与第三方向Q相平行;两组集装箱组1100沿储能集装箱100的第二方向P依次排列,也就是两组集装箱组1100沿箱体10的宽度方向进行排布;此时,两组集装箱组1100共四个储能集装箱100形成田字格排布,同一组集装箱组1100中的两个储能集装箱100沿第一方向O相靠拢摆放,且两个储能集装箱100呈镜像对称;两组集装箱组1100中的集装箱呈背靠背式摆放,即其中一组集装箱组1100的两个储能集装箱100和另一组集装箱组1100的两个储能集装箱100分别呈背靠背式靠拢摆放,两组集装箱组1100呈镜像分布。
如此设置,两组集装箱组1100沿第二方向P排布且呈镜像分布,由此,四个储能集装箱100可以形成田字格的排布方式相靠拢摆放,相比于将四个储能集装箱100呈间隔式摆放的方式,能够进一步地提高占地的单位面积能量密度;且两组集装箱组1100依次排列,能够减少两组集装箱组1100之间的距离,进而减少对两组集装箱组1100的维护距离,以提高现场操作的便利程度。
请参考图1和图8,在一些实施例中,在第二方向P上排列的两个储能集装箱100的电气仓30相邻设置。
如此设置,可以在第二方向P上的同一侧对两个储能集装箱100的电气仓30同时进行观察和维护,有效地提高了维护的便捷性。
以上仅为本申请的较佳实施例而已,并不用以限制本申请,凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本申请的保护范围之内。
