Vehicle Battery Charging Lockout for Secure External Commands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle charging systems are vulnerable to unauthorized modification of charging commands, such as deferred charging, when the charging hatch is left open, allowing anyone to press the control button and cancel ongoing charging.
Innovation Solution
A security measure involving a neutralization device that locks the control device if the passenger compartment is secured, incorporating a time delay to ensure that charging commands remain unchanged unless the compartment is unlocked after a predetermined time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the charging hatch is left open to allow external control operation, then the control device is accessible for charging operations, but unauthorized persons can modify charging commands
Solution Approach 1:
The system performs preliminary verification by checking the locking state of the passenger compartment before accepting charging commands. The control device proactively checks whether the opening (door/hatch) is locked, and only processes commands when the vehicle is parked and secured, preventing unauthorized modifications while allowing legitimate external control operations
2Reliability
If a neutralization device is added to prevent unauthorized control, then charging command security is improved, but device complexity increases
Solution Approach 1:
The control device continuously receives feedback signals from the vehicle's locking system to determine the current state of the passenger compartment. This feedback mechanism allows the control device to dynamically adjust its acceptance of charging commands based on whether the vehicle is locked, providing security without requiring a separate complex neutralization device
Solution Approach 2:
The control device is designed to perform multiple functions: it controls charging operations, verifies locking state, and determines whether to accept or reject commands. By integrating these functions into a single multi-functional control unit, the system achieves security requirements without significantly increasing overall device complexity
