The invention discloses a hybrid electric vehicle energy management method, device and system and a storage medium. The method comprises the steps that 1, multi-source traffic information and vehicle state information in the vehicle running process are collected; 2, extracting traffic elements influencing the driving of the hybrid electric vehicle according to the multi-source traffic information and the vehicle state information, and constructing the multi-source traffic information of a graph structure; 3, training a vehicle speed prediction model of a long-short term network based on the graph convolutional neural network according to the multi-source traffic information of the graph structure, and predicting the future vehicle speed by using the trained vehicle speed prediction model; and step 4, according to the predicted vehicle speed, performing energy management considering energy consumption and life decline of a vehicle power system. By adopting the technical scheme of the invention, the influence of the traffic elements on the sub-vehicles is fully utilized, the speed sequence which more accords with the reality is predicted, and the energy management economy is improved.
