Abstract: Small unmanned undersea vehicles(UUVs) generally use 18650 lithium-ion battery packs, whose thermal characteristics directly affect the service performance and thermal safety of the UUVs. To design a heat dissipation system and develop a safety strategy for this battery pack, it is crucial to study its heat generation characteristics. In this study, an equivalent circuit-thermal coupled model of the cylindrical lithium-ion battery is established, and the equivalent circuit parameters and thermal parameters of the 18650 battery are identified. Further, a thermal simulation and experiment are performed on a small UUV battery pack, and the simulation results are in good agreement with the experimental results; thus, the validity of the equivalent circuit-thermal coupled model is proved. This study provides a technical reference for the thermal management of battery packs of undersea vehicles.
