Schedule Display for Aligning Battery Charging With Demand Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy management systems, such as those described in WO 2020/100288, do not adequately provide a user interface for administrators of power storage devices to select and participate in demand response (DR) programs, particularly in matching charging or discharging schedules with DR timing, which can lead to inefficiencies in power usage and participation in economic DR opportunities.
Innovation Solution
A display device that acquires and simultaneously displays scheduling information for power storage device operations and DR requests, allowing users to easily identify and adjust charging or discharging schedules to align with DR timings, including distinguishing between different types of DR and supply-and-demand conditions, enabling users to participate in desired DR programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If timer charging is used to charge at predetermined time zones, then charging schedule is fixed and simple to manage, but it cannot adapt to irregular DR timing and miss economic DR opportunities
Solution Approach 1:
The charging schedule is made dynamic by allowing users to adjust and modify charge/discharge timing based on DR requests. The system transitions from fixed timer charging to flexible scheduling where users can shift charging operations to align with DR time zones while maintaining overall schedule manageability through the display interface.
2Productivity
If automatic charging plan generation is implemented, then charging efficiency is improved, but user control and interface for selecting DR programs are insufficient
Solution Approach 1:
The system provides visual feedback through the display interface showing DR requests, charge/discharge schedules, and timing alignments. Users can see how their charging plans interact with DR opportunities and make informed adjustments. This feedback loop maintains user control while preserving the efficiency benefits of automated plan generation.
3Ease of operation
If DR participation is automated without user interface, then system operation is simplified, but user awareness and selection of desired DR programs are reduced
Solution Approach 1:
The display interface acts as an intermediary between the automated DR participation system and the user. It translates complex DR requests and scheduling information into visually accessible formats, enabling users to understand and monitor DR participation without adding operational complexity to the system.

AI summary
A mobile terminal functioning as a display device includes a first acquisition unit that acquires a first schedule indicating a time period in which charging or discharging of the power storage device is scheduled, a second acquisition unit that acquires a second schedule indicating a time period in which a demand response requesting charging or discharging of the power storage device is scheduled, and a display unit that displays a schedule window. The display unit simultaneously displays the first schedule and the second schedule on the schedule screen in an identifiable manner.
