EV Charging Interlock Using Connector Detection to Disable Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle charging systems lack effective methods to safely disable electric vehicles during charging, posing safety risks.
Innovation Solution
A system comprising a charging port, sensor, and interlock component that detects the engagement of a charging connector and generates a charging datum to disable the electric vehicle by disconnecting the energy storage device from the load, ensuring the vehicle remains inactive while charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric vehicle remains operational while charging, then the vehicle maintains operational flexibility, but safety risks increase during the charging process
Solution Approach 1:
The system performs preliminary detection of charging connector engagement through charging sensors before disabling the electric vehicle. The controller proactively monitors charging status and preemptively disables vehicle operation when charging is detected, preventing safety issues before they can occur while maintaining operational flexibility when not charging.
2Reliability
If the electric vehicle is disabled during charging, then safety is enhanced, but the vehicle cannot operate or move while plugged in
Solution Approach 1:
The system continuously monitors charging status through charging sensors and provides feedback to the controller. When the sensor detects charging connector engagement, the controller receives this feedback and automatically disables vehicle operation. When charging is removed, the system detects this change and restores operational capability, creating a dynamic safety mechanism that adapts to charging state.
3Reliability
If charging connection detection is implemented, then safety control is improved, but system complexity increases with additional sensors and control logic
Solution Approach 1:
The charging sensors serve multiple functions: detecting charging connector engagement, monitoring charging status, and providing input for vehicle disable/enable control. The controller integrates charging detection with existing vehicle operation control systems, allowing the same control unit to manage both charging safety and general vehicle operations, thereby reducing overall system complexity.
