Remote EV Charging Power Control via User Inquiry Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply control systems for electric vehicle charging services lack convenience in operation, particularly for users unfamiliar with the systems, as they require direct interaction with unfamiliar power supply apparatuses.
Innovation Solution
A power supply control apparatus that includes an acquisition unit for determining users, an inquiry destination determination unit for identifying user terminals, a transmission/reception unit for sending inquiry information, and a control unit for managing power supply operations based on user responses, allowing users to control power supplies remotely through familiar terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users directly operate power supply apparatus to control power supply, then power supply control function is achieved, but operational convenience deteriorates for unfamiliar users
Solution Approach 1:
The patent introduces a user terminal as an intermediary device between the user and the power supply apparatus. The control unit receives operation inputs from the user terminal and transmits control signals to the power supply apparatus, allowing users to operate familiar terminals rather than directly interacting with unfamiliar power supply equipment, thereby improving ease of operation
Solution Approach 2:
The patent divides the power supply control system into separate functional components: the user terminal for input operations, the control unit for processing and signal transmission, and the power supply apparatus for executing power control. This segmentation allows each component to specialize in its function, with the user terminal handling user interaction and the power supply apparatus focusing on power delivery, reducing the operational complexity users face
2Ease of operation
If power supply control is centralized through control unit, then operational convenience is improved, but system complexity increases
Solution Approach 1:
The control unit serves multiple functions within the system: it receives operation inputs from the user terminal, processes control logic, transmits control signals to the power supply apparatus, and manages communication between components. By consolidating these diverse functions into a single control unit, the system achieves centralized control that improves user convenience while managing complexity through functional integration

AI summary
To improve convenience of an operation for power supply control in a charging service, a power supply control apparatus according to the present disclosure includes: an acquisition unit that acquires, by using an information acquisition apparatus, user determination information that determines a user; an inquiry destination determination unit that determines information about an inquiry destination terminal of the user, based on the user determination information; a transmission/reception unit that transmits inquiry information about use of a power supply apparatus to the inquiry destination terminal; and a control unit that controls a power supply from the power supply apparatus in response to a response to the inquiry information.
