具体实施方式
下面结合附图和实施例对本申请的实施方式作进一步详细描述。以下实施例的详细描述和附图用于示例性地说明本申请的原理，但不能用来限制本申请的范围，即本申请不限于所描述的实施例。
在本申请的描述中，需要说明的是，除非另有说明，“多个”的含义是两个以上；术语“上”、“下”、“左”、“右”、“内”、“外”等指示的方位或位置关系仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”、“第三”等仅用于描述目的，而不能理解为指示或暗示相对重要性。“垂直”并不是严格意义上的垂直，而是在误差允许范围之内。“平行”并不是严格意义上的平行，而是在误差允许范围之内。
在本申请中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本申请所描述的实施例可以与其它实施例相结合。
下述描述中出现的方位词均为图中示出的方向，并不是对本申请的具体结构进行限定。在本申请的描述中，还需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可视具体情况理解上述术语在本申请中的具体含义。
目前，从市场形势的发展前景及应用趋势来看，由于电池单体具有能量密度高、功率密度高、循环使用次数多和存储时间长等优点，已经在多种领域中得到广泛的利用，如被应用于水力、火力、风力和太阳能电站等储能电源系统中。由于电池单体自身的特性，集中应用时出现安全隐患，易产生连锁反应，如电池单体集体自燃等，故目前本领域中储能系统多架设有专用的消防组件，以实现对电池单体的储能利用。但是目前，现有的储能系统中多采用烟感测温器，其结构较为复杂，在电池单体基数庞 大的储能系统中，应用烟感测温器需要引入更多复杂且众多的线路结构，不仅加重了前期施工的难度，还易对消防作业造成影响。
本申请发明人注意到，为了解决该问题，目前本领域中尝试采用片区检测的方式，具体为利用一烟感测温器检测储能系统中的一片区域，而在实际使用中，该方式不仅对控制系统的硬件具有较高要求，也会造成检测精度下降的问题。
为了缓解现有储能系统中的消防缺陷，申请人研究发现，可以通过优化储能系统的整体架构，并选择新型的测温方式来达到即获得较高检测精度，又精简了储能系统整体架构的目的，便于消防作业的进行，降低施工难度及架设成本，具有普遍适用性。
基于以上考虑，为了解决现有储能系统中的消防问题，本申请发明人经过深入研究，设计了一种储能系统及储能系统的消防方法。

S20.喷淋，控制消防组件3的喷淋头31喷洒；
S30.接收第二消防信号；
S40.转移，控制堆垛装置4将对应的储存组件1转移至消防组件3的消防槽32；
S50.控制消防槽32进行消防；
其中，第一消防信号为测温光纤22在感测到的电池单体10内温度达到阈值时发出的信号，第二消防信号为喷淋后接收到的进行消防槽32 消防的信号，如喷淋后，测温光纤22测得电池单体10温读降低至阈值或者喷淋时间达到时间阈值。
图10是本申请中消防方法再一实施方式的流程示意图。在一些可选实施方式中，可选地，如图10所示。S40.控制消防槽32进行消防步骤包括：
S1.浸没，控制移动组件322将储存组件1在槽体321内浸没；
S2.接收第三消防信号；
S3.移出，控制移动组件322将储存组件1从槽体321内移出；
其中，第三消防信号为槽体321内温度传感器323发出的温度信号或者接收到的消防工作停止信号，如温度传感器323测得的温度低于阈值或者浸没时间达到时间阈值。
与现有技术相比，本申请实施方式的储能系统中，通过防火组件2与储存组件1的对应设置，能够精确的发现着火点，便于精确定位起火点，其次，通过使用测温光纤22，能够使储存系统对火情的响应更灵敏，使消防措施迅速启动，并处理火情，其三，通过测温光纤22的弯折设置，能够使测温光纤22获得更多面向储存组件1的部分，提高测温进度及响应速度。
虽然已经参考优选实施例对本申请进行了描述，但在不脱离本申请的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件，尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本申请并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
