用于锂离子电池的灭火方法、灭火系统、电子设备及存储介质
本公开要求在2018年07月30日提交中国专利局、申请号为201810853120.4的中国专利申请的优先权，以上申请的全部内容通过引用结合在本公开中。
技术领域
本文涉及锂电池安全防护领域,并且更具体地，例如涉及一种用于锂离子电池的灭火方法、灭火系统、电子设备及存储介质。
背景技术
锂离子电池具有容量大、工作电压高、循环寿命长、体积小、重量轻等优点，应用于较多场景。在电动汽车和储能系统中，电源的动力电池要求具有较大的容量和电压，需要将多个单体电池装置于电池箱内，通过串、并联形成电池组来达到动力源的要求。多个电池箱组合构成的锂离子电池系统，需要加强检测，减小或消除安全隐患。
锂离子电池由于能量密度高，以及电池本身的结构特点，一旦发生燃烧不易扑灭，并且对于大批量电池集中放置的场景，比如电池箱、电池模块、电池货架等，当电池开始燃烧可能会引发连锁反应，使相邻电池陆续引燃，酿成火灾，这种情况下电池的燃烧更不易扑灭。
对于锂离子电池的燃烧，采用的传统的扑灭技术不易扑灭，并且电池柜、电池箱和电池单元的电池性能存在差异，当发生火灾隐患或明火时，往往力度和火势大小不一，如果用传统的扑灭方式，一方面无法保证大火的高效完全扑灭，或者电池明火一次扑灭后是否复燃，后续电池会不会出现连锁反应，同时由于不能根据火势大小控制灭火剂用量，经济性不高。
因此，需要一种能保证锂离子电池的明火高效完全地扑灭，同时又能节省灭火剂的灭火方法和策略。

在步骤104，使灭火装置根据灭火指令执行灭火动作。
在本可选实施方式中，当电池的温度上升到大于等于65℃或烟浓度达到阈值，被烟雾传感器感知时，启动安全等级为二级对应的灭火控制程序对电池进行降温，此时，启动降温型灭火剂，并通过温度传感器判断电池温度、电池周围温度变化，当温度下降到65℃以下后停止喷射。
当电池箱内的火焰传感器检测到明火燃烧时，启动安全等级为一级对应的灭火控制程序以降低空气中的氧含量、抑制火势蔓延，此时，启动窒息型灭火剂灭火，并通过火焰传感器判断是否扑灭明火，在电池初期火焰被扑灭后，关闭电池周围空间，继续喷射窒息型灭火剂，使电池柜体内充满窒息型灭火剂后停止喷射，保持5min-10min，这期间持续喷射降温型灭火剂，这期间如果出现复燃，则重新启动窒息型灭火剂，直到二次扑灭为止，二次扑灭后继续保持5-10min；之后，启动风扇或者打开电池柜体空间，使柜体内因燃烧产生的热量散失出去，通过温度传感器判断柜体内电池温度是否降低至阈值，当降低至阈 值后，继续监测电池温度，如电池温度上升，则继续喷射降温型灭火剂，直至电池温度开始下降。当电池温度降低至阈值以下并且温度无上升趋势，保持30min-1h后，启动风扇或打开柜体空间，防止人员靠近，继续通过温度传感器检测，直到电池温度降至室温，解除火灾状态。
