A learning apparatus includes: a learning part that performs, based on charging/discharging data indicating at least one of charging and discharging of a secondary battery that supplies electric power for traveling of a vehicle, a capacity learning of the secondary battery and that performs the capacity learning in response to a change amount of a charging rate that is indicated by the charging/discharging data exceeding a threshold value; and a threshold determination part that determines the threshold value based on history information of the learning part performing the capacity learning in a predetermined period.

Learning apparatus, learning method, and program

A presentation device includes an acquirer configured to acquire a usage status of a secondary battery which is the usage status of a secondary battery with which a plurality of vehicles including a target vehicle are equipped and includes one or more items, a deriver configured to derive representative values of items of the secondary battery in a vehicle in a predetermined area, and a presenter configured to present a relationship of items of the usage status of a secondary battery with which the target vehicle is equipped with respect to the representative values derived by the deriver.

Presentation device, presentation method, and storage medium

A diagnosis system includes: a charging control part that controls, upon connection between a vehicle and a charger provided at an outside of the vehicle, charging from the charger to a secondary battery provided on the vehicle; and a derivation part that derives a degradation degree of the secondary battery based on a change amount of a charging rate of the secondary battery and an integration value of a charging current of the secondary battery, wherein the charging control part determines, based on a remaining time until a next departure time of the vehicle, whether specific charging in which a charging pause period is provided in a middle of a charging time of the secondary battery is performed.
