In order to address the severe consequences of lithium battery vehicle fires during ship transportation，a vehicle fire simulation model of a ro-ro ship deck lithium battery was constructed. Firstly，the accuracy of the fire simulation model of single and dual lithium battery vehicles was verified by using the full-scale fire experiment data of lithium battery vehicles. Then，the verified simulation model was applied to simulate the fire of a lithium battery vehicle on the deck of a ro-ro ship，and the variation rules of fire heat release rate，temperature and radiant heat under different vehicle spacing were analyzed. The results show that in the initial stage of the lithium battery vehicle fire，the flame first spreads to the side-parked vehicles，especially the side of the vehicle affected by the jet fire，and then expands to the front and rear vehicles. The front vehicle suffers significantly more fire damage than the rear vehicle. At the same time，jet fire aggravates the spread and development of lithium battery vehicle fires. The temperature of the area with jet fire is significantly higher than that of the area without jet fire，and the adjacent vehicles affected by jet fire are ignited first. The numerical simulation method can effectively simulate the fire development and spreading process of the vehicle carrying lithium battery on a ship.
