Battery passive equalization control method and vehicle

The invention relates to a battery passive equalization control method and a vehicle, belongs to the technical field of batteries, and aims to solve the problems of poor effect and error equalization in battery cell equalization in the prior art. The battery passive equalization control method comprises the following steps: acquiring an equalization capacity difference initial value, updating the capacity difference initial value when a capacity difference updating condition is met, and if the capacity difference of a certain battery cell is greater than a set threshold value, determining that the battery cell is a battery cell. Marking that the battery cell needs to be balanced; the updating condition of the initial value of the capacity difference comprises that when the single voltage is in a non-platform area, the difference value between the capacity difference of a certain battery cell and the capacity difference of the minimum battery cell is greater than a certain set range; and when the battery cell
