The invention relates to the technical field of energy management, in particular to an energy management technology aiming at a marine direct current hybrid power system, and particularly relates to an energy management method aiming at the marine direct current hybrid power system composed of multiple groups of fuel cells, multiple groups of lithium batteries and a super capacitor. By monitoring information such as bus voltage and residual electric quantity of each power supply, each power supply DC/DC converter in the marine direct-current hybrid power system is controlled, so that the hybrid power system is switched among 11 working modes, flow of energy in the hybrid power supply is timely allocated, the stability of the direct-current bus is ensured, and the service life of the hybrid power supply is prolonged. The hybrid power supply system rapidly tracks load changes, and stable and reliable operation of the whole DC hybrid power system is realized.
