Abstract: A charging control method includes setting at least a first threshold value and a second threshold value larger than the first threshold value as threshold values with respect to a remaining capacity of a storage battery unit included in each of a plurality of work devices. The method includes outputting, in a first state where the remaining capacity of the storage battery unit included in a work device designated as a target of control is equal to or greater than the first threshold value but less than the second threshold value, a charging start instruction to the work device when a predetermined decision condition is satisfied. The method further includes outputting, in a second state where the remaining capacity of the storage battery unit is less than the first threshold value, the charging start instruction to the work device, no matter whether the condition is satisfied or not.
