The invention belongs to the technical field of cargo ship energy management methods, and particularly relates to a hybrid power cargo ship energy management method and device based on a low-pass filter, and the method comprises the steps: obtaining the information of a research object, determining the analyzed frequency characteristics according to the information of the research object, and carrying out the analysis of the frequency characteristics; the frequency characteristic is used for representing and analyzing the frequency domain characteristic of the cargo ship demand power; and according to the result of the analyzed frequency characteristics and a Kalman filtering algorithm. Therefore, for the fuel cell hybrid power cargo ship, the real-time required power of the whole ship is acquired to perform frequency feature extraction so as to construct the online filter, the low-pass cut-off frequency is updated in real time, and online real-time fuel cell output power low-pass filtering for random working conditions is realized. Moreover, an excellent optimization algorithm is adopted, and the durability of the fuel cell is effectively improved, the economical efficiency of the fuel cell is optimized, the efficiency of the fuel cell system is improved, and the durability of the supercapacitor is improved through power distribution.
