  • Patent number: 11934195
    Abstract: A charging control system includes a lawn mower that includes a battery and performs a lawn mowing work while traveling autonomously, and a charging station for charging the battery. The lawn mower includes a superimposing unit for superimposing, on a charging current, a current indicating period information for defining a shutoff period of supply power to be supplied from the charging station. The charging station includes a current detector for detecting the charging current, an information acquisition unit for acquiring period information based on a detection result of the current detector, a switch for shutting off the supply power, and a shutoff controller for controlling the operation of the switch. The shutoff controller releases the shutoff of supply of power to the lawn mower based on the period information acquired by the information acquisition unit. Therefore, the power consumption of the lawn mower can be reduced.
