Claim 9:
10. A mower fleet management method for controlling a plurality of mowers to work in collaboration, the method comprising:
acquiring a map of a working land and status information of the plurality of mowers, wherein the status information comprises at least one of charge amount of battery, speed and mowing widths of the plurality of mowers; and
assigning a working region to each of the mowers according to the status information and the map and guiding each of the mowers to work in the corresponding working region;
evaluating working area value of each of the plurality of mowers according to the status information of each of the plurality of mowers;
generating a working path of each of the plurality of mowers according to the estimated working area value of each of the plurality of mowers and the map of the working land;
estimating the working area value of each of the plurality of mowers; and
determining whether a sum of the estimated working area values of all of the plurality of mowers is not less than an area value of the working land; and if so, generating a working path of each of the plurality of mowers according to the estimated working area value of each of the plurality of mowers and the map of the working land, or
determining whether a mower outside the fleet is needed to be added; and if so, adding the mower outside the fleet to a current fleet and evaluating working area value of each of the plurality of mowers according to the status information of each of the plurality of mowers;, wherein, an estimation equation for the working area is:

Simax=Bi*SOCi*Ki, or

Simax=(Bi−Bimin−Biback)*SOCi*Ki, or

Simax=(Bi−Bimin−Biback)*SOCi*Ki*(1−Fi),, wherein Simax is an estimated working area of an ith mower, Bi is a current battery percentage of the battery of the ith mower, and Ki is a ratio of a mowing area to power consumption of the ith mower, SOCi is a full charge of a battery of the ith mower, Bimin is a preset minimum battery percentage for the battery of the ith mower, Biback is a preset back battery percentage according to a distance between a position of the mower when work completed and a starting point, Fi is a preset re-mowing rate for the ith mower.
