Integrated Authentication Element in EV Charging Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of electric vehicles face inconvenience as they need to carry a separate authentication card for charging, which can be forgotten or lost, preventing vehicle charging if not available.
Innovation Solution
Integrating an authentication element directly into the vehicle-side connector, allowing automatic authentication when plugged into the charging station, eliminating the need for a separate authentication card.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate authentication card is used for charging, then payment verification can be performed, but the user must carry and remember to bring the card, increasing the risk of forgetting or losing it
Solution Approach 1:
The authentication element is integrated directly into the vehicle-side connector, merging the authentication function with the charging connection function. This eliminates the need for a separate authentication card, as the connector itself now contains the authentication capability. The user simply needs to plug in the charging cable, and authentication occurs automatically through the integrated element.
2Reliability
If an authentication card is required, then payment can be verified, but the user experiences inconvenience and potential charging failure if the card is forgotten or lost
Solution Approach 1:
The authentication element is pre-integrated into the vehicle-side connector during manufacturing. This preliminary integration ensures that authentication capability is already in place before the charging event occurs, eliminating the need for users to prepare or retrieve a separate authentication card at the time of charging.
3Reliability
If a separate authentication card is used, then authentication can be performed, but the overall system complexity increases due to the need for separate authentication and charging components
Solution Approach 1:
The patent merges the authentication function with the charging connector by integrating an authentication element (such as an RFID tag or NFC chip) directly into the vehicle-side connector. This consolidation reduces the number of separate components users must handle and simplifies the overall system architecture by combining two previously separate functions into one integrated unit.
