Load control method and device for auxiliary source circuit, terminal and storage medium

The invention provides a load control method and device for an auxiliary source circuit, a terminal and a storage medium. The auxiliary source circuit is provided with a plurality of auxiliary source branches for output; the method comprises the steps that a first auxiliary source branch to be sampled and a second auxiliary source branch to be controlled are determined, the first auxiliary source branch is the auxiliary source branch with the minimum load in all the auxiliary source branches, and the second auxiliary source branch is the auxiliary source branch with the maximum load in all the auxiliary source branches; sampling the input voltage of the first auxiliary source branch according to a set sampling frequency, and calculating a predicted voltage value according to the voltages sampled for two adjacent times; after the load task of the second auxiliary source branch is changed, whether the predicted voltage value exceeds a preset range or not is judged; wherein the load task change comprises load lo
