Abstract: The safety design of the power source of lithium battery-powered ships is significantly different from that of conventional powered ships according to the characteristics of lithium batteries. In order to ensure the safe usage of the lithium battery, a lithium battery-powered inland river ferry is examined to study the current safety design measures of the lithium battery(including the requirements for single battery, battery cells and battery management system), the ship battery compartment layout, the ventilation schemes and the design of the fire-fighting system. The fixed HFC-227C fire extinguishing system is calculated and checked according to the requirements of relevant codes. The safety requirements of current rules for the lithium battery power have been met through a series of safety designs. Finally, the limitation of the design scheme and the disadvantage of using fire extinguishing media are pointed out.
