A battery exchange guiding method includes: searching for a battery station (20) that an electrically powered vehicle (10) is able to reach (first search); and searching for the battery station (20) in which a battery (21) with a larger SOC than a predetermined value (an SOC required to reach a destination from the battery station (20) + a user's desired value in regard to a remaining amount of the SOC at a timing of arrival at the destination) is stored (second search). The guiding method includes notifying the user of the electrically powered vehicle (10) of information on the battery station (20) extracted through the above two searches.
