Voltage discreteness estimation method and device of satellite lithium battery pack and electronic equipment

The invention provides a voltage discreteness estimation method and device for a satellite lithium battery pack and electronic equipment. The method comprises the steps that the maximum voltage difference of the current lithium battery pack is acquired; judging whether the maximum voltage difference exceeds a consistency deviation triggering threshold value or not; under the condition that the maximum voltage difference exceeds a consistency deviation triggering threshold value, a historical voltage data set of the lithium battery pack is obtained, and the historical voltage data set comprises historical voltage data of all single batteries in the lithium battery pack in a fully-charged state; and a first-order linear fitting method is adopted to fit the change of the maximum voltage difference of the lithium battery pack along with the time in the full charge state, the function relation delta U = f1 (t) between the maximum voltage difference of the lithium battery pack and the time is obtained, delta U is t
