1. A charging control method comprising:
setting processing including setting at least a first threshold value and a second 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 second threshold value being larger than the first threshold value; and
charging control processing including designating one of the plurality of work devices as a target of control and controlling, based on the remaining capacity of the storage battery unit included in the work device designated as the target of control, charging of the storage battery unit,
the charging control processing including outputting, in a first state where the remaining capacity of the storage battery unit included in the work device designated as the 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 designated as the target of control when a predetermined decision condition is satisfied, the charging start instruction being output to instruct the work device designated as the target of control to start charging,
the charging control processing further including outputting, in a second state where the remaining capacity of the storage battery unit included in the work device designated as the target of control is less than the first threshold value, the charging start instruction to the work device designated as the target of control, no matter whether the predetermined decision condition is satisfied or not,
the setting processing including further setting a third threshold value as another one of the threshold values,
the charging control method further comprising charging end processing including outputting, when the remaining capacity of the storage battery unit included in the work device designated as the target of control becomes equal to or greater than the third threshold value while the work device designated as the target of control is being charged, a charging end instruction to the work device designated as the target of control, the charging end instruction being output to instruct the work device designated as the target of control to finish charging,
the third threshold value including a first end decision threshold value and a second end decision threshold value,
the first end decision threshold value being a threshold value applicable to a situation where no work devices other than the work device designated as the target of control have the storage battery unit, of which the remaining capacity is less than the second threshold value, while the work device designated as the target of control is being charged,
the second end decision threshold value being a threshold value applicable to a situation where some work devices other than the work device designated as the target of control have the storage battery unit, of which the remaining capacity is less than the second threshold value, while the work device designated as the target of control is being charged,
the second end decision threshold value being lower than the first end decision threshold value,
the setting processing including setting a plurality of second threshold values, including the second threshold value, as the threshold values,
each of the plurality of second threshold values being larger than the first threshold value,
the setting processing including further setting a plurality of second end decision threshold values including the second end decision threshold value and corresponding one to one to the plurality of second threshold values, and
the setting processing including setting each of the plurality of second end decision threshold values at a value that increases as a corresponding one of the plurality of second threshold values increases.
