  • Publication number: 20220276688
    Abstract: An information processing device comprises a prediction unit configured to predict a first user who uses a storage apparatus that stores a power storage device in a first time period subsequent to a current time point. The prediction unit may predict the first user based on usage information that indicates usage history of a second user who used storage apparatus in a second time period prior to the first time period. The usage information may include information related to a time frame when the second user used the storage apparatus in the second time period. The prediction unit may predict that at least some of the second users who used, in the second time period, the storage apparatus during a time frame to which the first time period belongs use the storage apparatus in the first time period.
