Autonomous work system and method for controlling autonomous work machine

An autonomous working system, comprising:

• an autonomous work machine including a battery, the autonomous work machine being configured to move along a work route that sequentially passes through a plurality of work positions and performs a predetermined task at each of the plurality of work positions;
• a plurality of supplementary charging stations arranged along the work route, each of the plurality of supplementary charging stations being configured to charge the battery by wireless power transfer;
• and
• a controller, the controller being configured to obtain a remaining charge of the battery;
• to determine whether additional charging of the battery is necessary in a middle of the work route based on the remaining charge of the battery;
• and to determine the work route to move the autonomous work machine to one of the plurality of supplementary charging stations in the middle of the work route to perform the additional charging of the battery upon determining that additional charging is necessary.
