Battery Capacity Sharing Interface for Multi-User Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing secondary battery systems, such as NaS batteries, do not effectively provide discharge capacity to users other than the primary owner, leading to underutilization of their potential capacity.
Innovation Solution
A user interface providing device and method that acquires, determines, and displays the usable discharge capacity of a secondary battery system to multiple users, allowing them to access and utilize the system's charge-discharge capacity through a virtual server and client architecture, with priority management and account-based access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the discharge capacity of the secondary battery system is exclusively allocated to the main user, then the main user can fully utilize the battery capacity, but the capacity cannot be shared with other users leading to underutilization
Solution Approach 1:
The patent segments the discharge capacity of the secondary battery system into multiple usable capacity portions, each allocated to different users based on their login credentials and authorization levels. The control device divides the total discharge capacity into separate usable portions for the main user and other users, enabling simultaneous access and utilization by multiple users without conflict.
2Productivity
If the system allows multiple users to access the discharge capacity, then capacity utilization improves, but the system complexity increases due to user management requirements
Solution Approach 1:
The patent introduces a control device as an intermediary between the secondary battery system and multiple users. This control device manages user login authentication, determines usable discharge capacity for each user, and provides appropriate user interface screens. By centralizing these management functions in a dedicated control device, the system handles multiple user access without proportionally increasing overall system complexity.
3Reliability
If the main user retains full control over the battery system, then system reliability is maintained, but other users cannot access or utilize the discharge capacity
Solution Approach 1:
The patent applies local quality by providing different levels of access and control to different users. The main user retains full control and sees a comprehensive user interface screen showing total discharge capacity, while other users receive limited access with customized user interface screens showing only their allocated usable discharge capacity. This differentiated access approach maintains system reliability through the main user's full control while enabling other users to utilize the discharge capacity within their authorized boundaries.

AI summary
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.
