EV Charging Connector Detection for Return Completion Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging management systems for electric vehicles lack an efficient method to determine whether the charging connector is connected to the socket upon vehicle return, leading to incomplete return notifications and potential mismanagement of charging schedules.
Innovation Solution
A charging management system that includes an acquirer to acquire connection status information and a decider to determine if the charging connector is connected to the socket, ensuring accurate return completion verification and scheduling updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charging management system relies on user notification for vehicle return, then the system operation is simple, but the return completion determination is unreliable
Solution Approach 1:
The charging connector automatically performs the detection function by itself. When the connector is inserted into the vehicle socket, it autonomously detects the connection status through electrical contact without requiring external detection devices or user intervention. The connector's own structural components (contact pins, housing) serve as the detection mechanism, enabling the system to reliably determine vehicle return completion through self-service detection.
2Productivity
If the system checks connection status upon vehicle return, then the charging schedule management becomes accurate, but the operation process becomes more complex
Solution Approach 1:
The connection detection function is merged with the existing charging connector structure. The connector simultaneously serves as both the physical connection interface for power transfer and the detection device for determining vehicle return status. By combining these two functions into a single component, the system achieves accurate charging schedule management without adding separate detection devices or complicating the vehicle return operation process.

AI summary
Provided is a charging management system designed to make management by determining whether a charging connector of a charger is connected to a socket of an electric vehicle returned by a user. A charging management system includes an acquirer and a decider. The acquirer acquires connection status information indicating whether a charging connector of a charger is connected to a socket of an electric vehicle. The decider determines, depending on whether the connection status information acquired by the acquirer indicates that the charging connector is connected to the socket, whether return of the electric vehicle from a user is completed.
