The invention provides an extended-range vehicle energy management method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring historical vehicle speed information of a vehicle, and processing the historical vehicle speed information by using a pre-constructed vehicle speed prediction model to obtain a future predicted vehicle speed; calculating the power demand of the vehicle, and planning the change track of the state of charge of the battery according to the power demand of the vehicle and the predicted driving distance to obtain a reference track of the state of charge of the battery; according to the future predicted vehicle speed and the battery charge state reference trajectory, a preset target function of multi-target optimization control is converted into a nonlinear programming problem, the nonlinear programming problem is solved by using a genetic algorithm fused with an elite strategy, and an optimal energy management strategy is obtained; and performing energy management on the extended-range vehicle by using the optimal energy management strategy. The vehicle speed prediction accuracy is improved, the energy management efficiency of the extended-range vehicle is improved, and the complexity and cost of the scheme are reduced.
