Vehicle Refresh Charge Control Device Diagnostic Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inspectors face difficulties in determining whether charge control or idling stop control is not performed due to a refresh charge, as existing solutions like displaying execution states or recording event histories may lead to increased costs and communication complexity.
Innovation Solution
A charge control apparatus with a control device that executes a refresh charge under predetermined conditions and suppresses it when detecting specific inputs or vehicle operations, allowing for easier identification of the reason for non-performance through a problem-solving mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the execution state of the refresh charge is displayed on a display device or event history is recorded, then the inspector can easily determine the reason for non-performance, but additional cost and increased number of communication items occur
Solution Approach 1:
The control device automatically suppresses the refresh charge when detecting specific vehicle operations or external device inputs, making the system self-diagnostic. The suppression action itself serves as the diagnostic indicator, eliminating the need for separate display or recording systems while maintaining ease of determination for inspectors
Solution Approach 2:
The system uses the presence or absence of refresh charge suppression as a visible indicator state. When suppression occurs due to specific conditions, it creates a distinguishable state that inspectors can easily identify without additional communication protocols or display devices
2Reliability
If the refresh charge is executed to fully charge the battery, then the service life of the battery is preserved, but the charge control or idling stop control cannot be performed
Solution Approach 1:
The system dynamically adjusts between refresh charge execution and suppression based on real-time vehicle operations and external device inputs. The control mode switches between full refresh charge (for battery preservation) and suppressed state (for normal charge control operation), optimizing both battery service life and charge control availability according to actual conditions

AI summary
A charge control apparatus includes a control device configured to execute a refresh charge to fully charge a battery upon a predetermined refresh charge start condition being met, and execute a predetermined control according to a vehicle travel state under a situation where the control device does not execute the refresh charge, the predetermined control involving at least one of charging and discharging the battery. The control device suppresses the refresh charge when the control device detects at least one of a predetermined input from an external device and a predetermined vehicle operation.
