In an embodiment, a management method of a secondary battery is provided. In the management method, temperature control of the secondary battery is executed in a second period after a first period in which the secondary battery is diagnosed, when the secondary battery is charged under a charge condition under which precipitation of lithium metal in the secondary battery is predicted based on a diagnosis result in the first period. In the temperature control of the secondary battery, a temperature of the secondary battery after a time point of an end of charge under the charge condition in the second period is kept in a predetermined temperature range of a lower-limit temperature to an upper-limit temperature.
