Peak power test method and device, electronic equipment and storage medium

The invention discloses a peak power test method and device, electronic equipment and a storage medium, and the method comprises the steps: determining a target excitation current corresponding to a target charge state according to the corresponding relation between the charge state and the excitation current; repeatedly executing the first operation by adopting a plurality of test working powers; and according to each test working power and the corresponding test operation duration, determining a target working power corresponding to the target operation duration, and taking the target working power as a target peak power corresponding to the target operation duration. According to the scheme, on one hand, the test data is combined with the actual use condition of the power battery of the electric vehicle, so that the matching degree of the peak power obtained through the test and the actual working condition is enhanced, and the accuracy of the peak power test is improved; and on the other hand, the target
