1. An estimation system comprising:
a power storage device;
a charge device configured to charge the power storage device; and
one or more processors configured to:
execute a charge process of controlling the charge device so as to charge the power storage device, the charge process including a restricted charge process in which the one or more processors control the charge device so as to charge the power storage device such that a state of charge of the power storage device does not become more than an upper limit state of charge set to be lower than a full state of charge of the power storage device; and
execute an estimation process of estimating a full charge capacity of the power storage device, the estimation process including a process of estimating the full charge capacity by dividing an amount of charge by which the power storage device is charged through the charge process by ΔSOC that indicates an amount of increase in the state of charge through the charge process,
wherein the one or more processors are configured to:
execute the restricted charge process when a predetermined condition is not met; and
execute, when the predetermined condition is met, the restricted charge process with the upper limit state of charge of the power storage device set to a second upper limit state of charge that is more than a first upper limit state of charge that is the upper limit state of charge at a time when the condition is not met,
wherein the one or more processors are configured to determine that the predetermined condition is met when the upper limit state of charge is set by a user, and
wherein the one or more processors are configured to determine that the predetermined condition is met when a state in which the upper limit state of charge is set by the user has continued for a predetermined threshold time or more.
