Claim 6:
7. The method according to claim 1, wherein intercepting the stage current change curve corresponding to the target working stage from the original current change curve to obtain the target current change curve comprises:
discretizing the intercepted stage current change curve according to a first preset step length to obtain first discrete data;
acquiring the first discrete data beyond a preset error range as first overrun data;
discretizing the stage current change curve corresponding to a time period where the first overrun data is located according to a second preset step length to obtain second discrete data;
acquiring the second discrete data beyond the preset error range as second overrun data; and
fitting the second overrun data, a stage peak value and a stage valley value to obtain the target current change curve.
