1. A charging control method for an electric moving body that moves using a battery as a power source, the charging control method comprising:
setting, as a consumption amount of one day, a battery consumption amount from when the electric moving body departs a base charging location to when the electric moving body has returned to the base charging location, and calculating an estimated consumption amount of one day based on the consumption amounts of past n days;
setting, as a charging recommendation threshold value, a value obtained by adding the estimated consumption amount and a margin to a lower limit remaining capacity determined in advance;
transmitting a notification prompting charging of the battery to an on-board human machine interface of the electric moving body or a terminal of a user when a remaining capacity of the battery drops below the charging recommendation threshold value;
acquiring user feedback regarding whether the user has a worry about an electricity shortage of the battery through the on-board human machine interface or the terminal of the user; and
changing the lower limit remaining capacity to be higher in a case where the user feedback indicates that the user has the worry and keeping the lower limit remaining capacity unchanged in a case where the user feedback indicates that the user does not have the worry.
