Abstract: A path finder sets a plurality of nodes in a state of charge (SOC) zone that is between a target SOC, which is set when a secondary battery provided in an electric moving body is charged, and a present SOC, and sets a plurality of nodes in a chargeable time period that is between a charging start time and a charging end time. A cost assigner refers to at least one of storage degradation characteristics, charge cycle degradation characteristics, or a time-of-use electricity fee table to assign a cost of a degradation amount or an electricity fee to each path between nodes. The path finder finds the charging path that minimizes a total cost of the paths between the nodes. A charging plan creator creates a charging plan based on the charging path found.
