The system composition, principle and short-circuit characteristics of marine lithium iron phosphate battery power system are mainly described. The PNGV model of lithium iron phosphate battery, the calculation of DC filter selection and the working principle of DC converter are analyzed in detail. The parameters of PNGV model of lithium iron phosphate battery are obtained by HPPC test, and the optimal working area is selected according to the ripple characteristics of DC converter. Finally, starting from the system characteristics, the equivalent circuit of short-circuit in lithium iron phosphate battery power system is analyzed, and the short-circuit in battery side and DC grid side is deeply studied. The correctness of the theoretical analysis is verified by the simulation of MATLAB/Simulink platform.
