EV Charging Control with Shared Vehicle Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles face inconvenience due to the long time required for battery charging, leading to disconnection of operation and user dissatisfaction when multiple vehicles charge simultaneously or when power is insufficient for a destination.
Innovation Solution
An apparatus and method for controlling electric vehicle charging that includes V2X communication with a charging station management server and a vehicle management server to reserve a charging station and a shared vehicle, allowing users to transfer to a reserved shared vehicle while their electric vehicle charges, thereby minimizing waiting time and ensuring continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the electric vehicle charges the battery at a charging station, then the battery is charged, but the vehicle operation is disconnected and the user experiences inconvenience due to long waiting time
Solution Approach 1:
The system performs preliminary actions by automatically reserving a shared vehicle before the electric vehicle finishes charging. The processor detects when battery power is insufficient for the remaining journey, automatically reserves a shared vehicle through V2X communication, and prepares the transfer process, so that the user can immediately switch to the shared vehicle when charging is complete, minimizing waiting time.
Solution Approach 2:
The patent introduces a shared vehicle as an intermediary solution. When the electric vehicle needs to charge, the user transfers to a shared vehicle that serves as a mediator to continue the journey. This intermediary vehicle bridges the gap during the charging period, allowing the electric vehicle to complete charging while the user maintains mobility through the shared vehicle.
2Productivity
If multiple electric vehicles charge simultaneously at a charging station, then charging capacity is utilized, but the waiting time increases and user convenience deteriorates
Solution Approach 1:
The shared vehicle acts as an intermediary that decouples the charging process from the user's travel continuity. Multiple electric vehicles can charge simultaneously at the charging station without impacting user convenience, because each user has a pre-reserved shared vehicle to transfer to, eliminating the queueing effect that would normally occur when multiple vehicles charge at once.
3Stability of the object's composition
If the electric vehicle waits for charging completion before continuing journey, then the vehicle maintains operational continuity, but the total travel time increases
Solution Approach 1:
The system ensures continuity of useful action by maintaining the user's mobility throughout the charging process. Instead of stopping the journey entirely during charging, the user transfers to a shared vehicle that continues the trip, while the electric vehicle simultaneously completes charging. This parallel execution maintains journey continuity without adding idle waiting time to the total travel duration.

AI summary
An apparatus for controlling charging of an electric vehicle and a method therefor are provided. The apparatus includes a communication device that performs vehicle-to-everything (V2X) communication with a charging station management server outside the electric vehicle and a vehicle management server configured to manage shared vehicles and a processor that requests the charging station management server to reserve a charging station via the communication device and automatically requests the vehicle management server to reserve a shared vehicle to be used when the electric vehicle is charged, via the communication device, when a vehicle power for driving to a destination is insufficient.
