Abstract: An estimation system includes a power storage device and one or more processors. The one or more processors are configured to execute a charge process of controlling a charge device so as to charge the power storage device, and an estimation process of estimating a full charge capacity of the power storage device. The one or more processors are configured to execute the charge process with an upper limit state of charge of the power storage device set to a value that is more than a first upper limit state of charge when a predetermined condition is met, the first upper limit state of charge being the upper limit state of charge at the time when the predetermined condition is not met.

Abstract: A battery has an SOC-OCV characteristic having a flat region. When a stage change detecting unit detects an occurrence of stage change during traveling of an electrified vehicle, a discharge current integrating unit calculates a discharge current integrated amount. When external charging is started, a charge current integrating unit calculates a charge current integrated amount until the battery is fully charged. A full charge capacity calculating unit calculates a full charge capacity based on a storage amount at a time of the stage change, the discharge current integrated amount, and the charge current integrated amount.
