The embodiment of the invention provides a charging and discharging time period solving method and device, equipment and a storage medium, and relates to the technical field of V2G. The method comprises the following steps: firstly, establishing a minimum peak-valley difference rate function and a minimum cost function; and setting corresponding constraint conditions, solving according to the minimum peak-valley difference rate function, the minimum cost function, the constraint conditions and an established multi-objective optimization model by using a multi-objective genetic algorithm NSGA-II to obtain an optimal solution set, and obtaining an optimal charging and discharging time period according to the optimal solution set. The optimal charging and discharging time period is obtained by solving by taking the minimum peak-valley difference rate and the minimum user cost as calculation targets, and the obtained optimal charging and discharging time period fully considers the benefitsof the user side while reducing the peak-valley difference rate, so that the participation degree of the user can be greatly improved, and the method has good practical significance.
