Dynamic EV Charging Schedule Adjustment Without Cable Re-insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle charging systems require re-insertion of the charging cable to change a charging schedule, limiting flexibility and efficiency in power management.
Innovation Solution
An apparatus with a communication device to receive schedule change requests and acquire new charging parameters from a charging facility, and a control device to create and implement a new charging schedule without re-inserting the charging cable, allowing for dynamic power management based on real-time availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a charging schedule is created by the charging control apparatus, then the charging schedule can be established based on available power and current, but the charging schedule cannot be changed unless a charging cable is re-inserted
Solution Approach 1:
The charging schedule is made dynamic and changeable during the charging process. The vehicle's control device can receive new charging schedules from a terminal device and update the charging parameters in real-time communication with the charging control apparatus, allowing flexible adjustment without physical reconnection.
Solution Approach 2:
The mechanical action of re-inserting the charging cable is replaced by an electronic communication system. The terminal device and vehicle control device exchange charging schedule information through wireless or wired communication, substituting the physical mechanical operation with an electronic information transfer process.
2Productivity
If the charging infrastructure notifies the vehicles of available power parameters in real-time, then power distribution control can be achieved, but the system requires complex communication protocols like IEC61851
Solution Approach 1:
The terminal device serves multiple functions: it displays charging information, receives user input for schedule changes, communicates with the vehicle control device, and coordinates with the charging control apparatus. This multi-functional approach consolidates what would otherwise require separate specialized devices and protocols.
Solution Approach 2:
The terminal device acts as an intermediary between the user, the vehicle control device, and the charging control apparatus. It simplifies the communication by providing a unified interface that translates user requirements into charging schedule parameters, reducing the complexity of direct communication between all components.

AI summary
A method, for use in a charging system including a vehicle in which a battery is installed, a charging facility, and an information terminal, for changing a charging schedule of the battery after creating the charging schedule without re-inserting a charging cable includes: receiving a request for a change of the charging schedule; acquiring, from the charging facility, a charging parameter applied in a case where the charging schedule is changed in response to the request for the change of the charging schedule as received; and creating a charging schedule after the change using the charging parameter acquired from the charging facility.
