Abstract

A battery management system (110) includes: a charging controller (112) that controls charging of a secondary battery (102); a voltage sensor (121) that detects a voltage of the secondary battery; and a controller (113) that estimates an estimated range to which a battery level of the secondary battery belongs among multiple battery level ranges. Based on the detected voltage in a charging state among multiple charging states of the charging controller (112), the controller (113) tentatively determines a tentative range to which the battery level belongs among the multiple battery level ranges. Based on comparison between the tentative range and a past estimated range estimated in a past, the controller (113) estimates a current estimated range that is the estimated range of this time.
