User interface providing device, method of providing discharge capacity of secondary battery system, and method of providing charge/discharge capacity of secondary battery system

Abstract

Provided is a scheme of providing a plurality of users other than a main user such as an owner with a discharge capacity which a secondary battery system potentially has. A user interface providing device includes an acquisition part, a receiving part, a determination part, and a generation part. The acquisition part acquires a discharge capacity capable of providing to a whole plurality of users other than a main user in a discharge capacity of a secondary battery system. The receiving part receives a logon of a user included in the plurality of users. The determination part determines a usable discharge capacity for a logged-on user from the discharge capacity capable of providing to the whole plurality of users. The generation part generates information indicating contents of a user interface screen including a screen element indicating the usable discharge capacity for the logged-on user.
