The invention relates to the field of vehicle network interaction, in particular to an active anti-aging scheduling method and device for a vehicle-mounted power battery. The method comprises the steps that firstly, mathematical modeling is conducted on a scheduling problem, the equivalent cycle number of battery work is counted through an improved rain flow counting method to serve as a first target function, the aging condition of the battery in the working process can be more accurately quantified through the method, and the method can be matched with an online optimization algorithm to improve the efficiency of the battery; the method comprises the following steps: firstly, taking a total variance of a power grid load as a first objective function, realizing a function of online quantification of battery aging, secondly, taking the total variance of the power grid load as a second objective function, optimizing on-grid vehicle charging and discharging power by combining a particle swarm optimization algorithm, and finally, obtaining a group of optimal charging and discharging power solutions, so that the two objective function values are minimum and vehicle charging and discharging are guided. Compared with the traditional rain flow counting method, the improved rain flow counting method can more accurately quantify the aging condition of the battery.
