Innovation Solution
A computerized charging interface that includes an AC/DC charger, a data exchange interface connected to the vehicle's computerized subsystems, and a remote data connection for performing updates, backups, malware scans, and integrity checks, using dedicated software and communication protocols to ensure secure and efficient data exchange and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If basic charging functionality is provided, then charging capability is achieved, but cybersecurity protection and data exchange capabilities are insufficient
Solution Approach 1:
The patent combines charging functionality with cybersecurity protection, data exchange, diagnostics, and software updating into a single integrated charging station system. The control unit coordinates multiple functions including authentication, charging control, malware scanning, and firmware updates through unified communication interfaces, eliminating the need for separate dedicated systems for each function.
Solution Approach 2:
The charging station is designed with multi-functional capabilities beyond basic charging. The same communication interface and control unit handle authentication, data exchange, cybersecurity scanning, diagnostics, and software updates. This universal design allows a single charging station to perform multiple functions that would traditionally require separate systems.
2Reliability
If comprehensive data exchange and monitoring capabilities are added, then cybersecurity and diagnostics are improved, but device complexity increases
Solution Approach 1:
The patent introduces a control unit as an intermediary that manages all data exchange between the charging station and the vehicle's computerized subsystems. This control unit handles authentication, coordinates communication protocols, and manages data flow for monitoring, diagnostics, and updates, simplifying the interface architecture while enabling comprehensive data exchange capabilities.
3Reliability
If authentication and security protocols are implemented, then data protection is improved, but charging process time increases
Solution Approach 1:
The patent implements preliminary authentication and security protocol establishment before the charging process begins. The control unit performs mutual authentication between the charging station and the vehicle, establishes encrypted communication channels, and verifies digital signatures in advance. This preliminary security setup ensures data protection while allowing the actual charging process to proceed without repeated security checks.
