Charging Control Device for EV Battery Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging congestion occurs when vehicle battery charging is completed but the user is not present to retrieve the vehicle, causing delays for other users waiting to charge.
Innovation Solution
A charging control device and method that acquires the remaining charging time, user terminal position, and travel time to notify the user of charging completion, allowing them to return to the vehicle at the optimal time and potentially extend charging if needed, thereby avoiding congestion.

1Productivity
If the battery charging is completed and the user is notified, then the charging process is efficient, but the user may not return to the vehicle in time causing charging congestion
Solution Approach 1:
The system performs preliminary actions by calculating the travel time from the user's current position to the vehicle, and sends notifications at the optimal moment before charging completion. This allows the user to return to the vehicle exactly when needed, preventing charging congestion and ensuring efficient utilization of charging infrastructure.
Solution Approach 2:
The system continuously monitors the user's position via GPS and the battery's charging status, providing real-time feedback. Based on this feedback, the system dynamically determines when to send notifications, ensuring the user is informed at the precise moment when their return coincides with charging completion, thereby eliminating wait times for other users.
2Ease of operation
If the user is notified early of charging completion, then the user can plan their return, but the charging may complete before the user arrives causing congestion
Solution Approach 1:
The system calculates the user's travel time in advance based on their current position and the vehicle's location. Using this preliminary calculation, it determines the optimal notification timing that balances user convenience with charging station utilization, sending the notification precisely when the user's arrival will coincide with charging completion.
Solution Approach 2:
The notification timing is not fixed but dynamically adjusted based on real-time data including user position, travel speed, and charging status. This dynamic approach allows the system to adapt to changing conditions, ensuring both user convenience and optimal charging station utilization.
3Measurement precision
If the system monitors user position and charging status continuously, then accurate notification timing is achieved, but system complexity increases
Solution Approach 1:
The system leverages existing multi-functional components: the GPS receiver serves both navigation and position monitoring functions, the communication device handles both user communication and status updates, and the processor performs both charging control and travel time calculation. This multi-functionality reduces the need for additional dedicated components, maintaining simplicity while achieving precise notification timing.
