Vehicular Charge Control Apparatus Plug Connection Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular charge control systems lack efficient methods to determine the user's intention to charge and accurately detect plug connection abnormalities before initiating charging, leading to potential inefficiencies and user inconvenience.
Innovation Solution
A vehicular charge control apparatus that includes a charge intention determination unit to assess the user's charging intent, a plug connection state determination unit to verify the plug connection, and a notification process execution unit to inform the user of any connection issues, ensuring that abnormality detection occurs only when the user intends to charge, thereby reflecting the user's intention accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the plug connection state is continuously monitored regardless of user intention, then the reliability of charge operation is improved, but the device complexity and unnecessary notifications increase
Solution Approach 1:
The system performs preliminary detection of plug connection state before initiating charge operation. The control unit checks whether the plug is properly connected at the time when charge start is instructed, and only then proceeds with charging or displays notifications. This preliminary check ensures reliability without requiring continuous monitoring throughout all vehicle operations.
Solution Approach 2:
The control unit integrates the plug connection detection function within the existing charge control system, utilizing the same control unit that manages charge operations. This self-service approach eliminates the need for separate dedicated monitoring hardware, reducing device complexity while maintaining reliable detection capability when needed.
2Measurement precision
If the plug connection state is checked before charge operation, then the accuracy of abnormality detection is improved, but the loss of time for determination increases
Solution Approach 1:
The system performs plug connection detection at the precise moment when charge start is instructed, which is the critical timing before charge operation begins. This preliminary detection at the right moment ensures accurate abnormality detection without requiring prolonged monitoring periods, thus minimizing time loss while maintaining high measurement precision.
3Loss of information
If notifications are displayed for all plug connection states, then the completeness of information provided to user is improved, but the object-affected harmful factors increase due to unnecessary notifications
Solution Approach 1:
The notification system applies local quality by providing information selectively based on the specific operational context. Notifications are displayed only when plug connection abnormalities are detected at the time when charge start is instructed. This targeted approach ensures complete and relevant information is provided to users about actual charge-related issues while avoiding unnecessary notifications during other vehicle operations, thus eliminating user inconvenience from false alarms.
Solution Approach 2:
The control unit provides feedback to the user only when abnormal conditions are detected that actually affect charge operation. The notification system monitors plug connection state and provides feedback notifications specifically when the plug is not properly connected at charge start instruction time, ensuring users receive actionable information about charge-related problems without being disturbed by irrelevant status updates.

AI summary
A vehicular charge control apparatus in a vehicle controls a charge operation to the vehicle from an external power supply facility, by using a charge intention determination unit for determining whether a user of the vehicle has an intention to charge, a plug connection state determination unit for determining whether a charge plug is connected to the vehicle when the user's intention to charge is determined by the charge intention determination unit, and a notification execution unit for executing a predetermined notification process when loss of connection to the charge plug is determined by the plug connection state determination unit.
