EV Charging Security Control for Shared Station Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle charging security systems prevent sharing of charging stations, as they are designed to secure the charging event between a vehicle and a charging station, making it difficult to allow other vehicles to use the station when the connected vehicle has completed charging.
Innovation Solution
A system that includes a credential controller and a security controller, allowing vehicle owners to use their mobile devices to request disarmament or disabling of the charging security system, enabling the sharing of charging stations with other vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charging security system is activated to prevent unauthorized disconnection, then security against theft is improved, but sharing capability with other vehicles deteriorates
Solution Approach 1:
The security system transitions from a static locked state to a dynamic state where the lock can be remotely controlled. The microprocessor controls the lock mechanism to transition between locked and unlocked states based on received commands, enabling the system to adapt between security and sharing modes as needed.
Solution Approach 2:
A wireless communication intermediary (transceiver system) is introduced between the user and the security system. This intermediary allows remote control of the lock mechanism through wireless signals, enabling authorized users to disarm the security system without physical access to the vehicle, thus facilitating sharing while maintaining security.
2Reliability
If the charging port is locked to prevent disconnection, then security is improved, but ease of operation for authorized users deteriorates
Solution Approach 1:
The mechanical key-based lock system is replaced with an electronic control system. The microprocessor-controlled lock mechanism responds to wireless electronic signals rather than requiring physical key manipulation, enabling remote disarming and improving ease of operation for authorized users while maintaining security.
Solution Approach 2:
A wireless transceiver intermediary is introduced to transmit disarming commands remotely. This allows authorized users to disarm the security system from a distance without needing to physically access the charging port or vehicle, significantly improving ease of operation.
3Reliability
If the alarm is armed to generate alerts on disconnection, then security monitoring is improved, but usability for sharing deteriorates
Solution Approach 1:
The alarm system is made dynamic through remote control capability. The microprocessor controls the alarm to transition between armed and disarmed states based on received wireless commands, allowing the system to adapt between security monitoring and sharing modes as needed without compromising either function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the sharing of charging stations by allowing authorized users to disconnect and reconnect the charging cord securely, promoting collaboration and efficient use of charging infrastructure.
Implementation Method 1
The near field communication reader may be configured to receive the command request from the requesting device. The near field communication reader may be configured to perform an inductive coupling with the requesting device to receive the command request.
