摘要
电池安全是电池动力船舶发展的前提,也是国内外专家学者关注的焦点。电池动力船舶安全研究具有前瞻性,受数据可得性的影响,选用对数据依赖较小的事故树模型,从电池充换电的视角,将事故树引入到船舶充换电安全事故分析中,并采用布尔代数法、结构重要度公式、Trilith软件,研究了船舶充换电安全事故定量分析方法,系统分析了船舶动力电池充换电安全性。通过测算得到电池损坏、火灾爆炸发生概率分别为0.022 27和0.024 02。结果表明,可燃气体、导体静电、摩擦静电引发船舶火灾事故可能性较大;高温、过充、联锁问题等是造成船舶动力电池充换电安全事故的主要原因。
Battery safety is a premise of development of battery-powered ships.It is also focused by experts and scholars in China and abroad.Studies of safety of battery-powered ships are forward-looking.Due to availability of data,an accident tree model is used for it relies less on data.From a perspective of battery charging and replacement,a fault tree model is developed.Boolean algebra method,structural importance formula,and Trilith software are used to develop a quantitative analysis to systematically analyze charging safety of ships.The probability of battery damage and fire explosion is 0.022 27 and 0.024 02,respectively.The results indicate that combustible gas,conductor static electricity,and friction static electricity are main reasons for fire accidents of battery-powered ships.High temperature,overcharge,and interlocking problems are main reasons for charging accidents.
