The invention discloses a protection system of a marine lithium battery device and a control method of the protection system. According to the system, a ship battery pack classification protection system is established according to the importance degree of a protected object, the damage degree of a fault to the whole device and the fault recovery processing difficulty degree or the maintenance convenience, and the operation state of a lithium battery device is evaluated and subjected to safety protection decision making, so that the safety of the lithium battery device is improved. And the battery is effectively prevented from being damaged due to over-low or over-high electric quantity, over-low or over-high temperature and the like. Four elements such as fault nodes, fault states, evaluation parameters and judgment criteria are set for each protection category or subcategory, and data calculation and protection analysis are performed on the four elements through data acquisition, so that the analysis precision is improved, and fault misjudgment is reduced.

    本发明公开了一种船用锂电池装置的保护系统及其控制方法。该系统根据被保护对象的重要程度、故障对整个装置的危害程度以及故障恢复处理难易程度或维护的方便性,建立船舶电池组分类保护体系,通过对锂电池装置的运行状态进行评估和安全保护决策,有效防止电池因电量过低或过高、温度过低或过高等原因而受到损害。并针对每一保护类别或子类别设置故障节点、故障状态、评估参数和判断准则等四大要素,通过数据采集,对应四大要素进行数据计算与保护分析,提高分析精度,减少故障误判。
