Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current charging methods for electric vehicles are complex and cumbersome, requiring identification and authorization processes, and often involve bulky control units that complicate handling and increase the risk of damage during charging.
Innovation Solution
A modular, compact charging cable with a bypass switch that allows for automatic control unit activation based on the type of energy supply unit, eliminating the need for separate control units and simplifying the charging process by enabling 'plug and play' functionality with various energy sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a control unit (ICCB) is integrated into the charging cable for continuous current power outlets, then the charging process can be controlled and monitored, but the charging cable becomes bulky, heavy, and complex to handle
Solution Approach 1:
The charging system is segmented into two distinct types of connection devices: one for charging stations with built-in control and one for continuous current power outlets without control units. This segmentation eliminates the need for an integrated control unit in the charging cable itself, reducing its complexity and bulk while maintaining reliable control where available.
Solution Approach 2:
The charging cable is designed with universal adaptability to work with both charging stations (with control) and continuous current power outlets (without control). By using a standardized connection device that can function in both modes, the system achieves multi-functionality without requiring separate specialized cables or integrated control units in the cable itself.
2Reliability
If a control unit (ICCB) is integrated into the charging cable, then charging can be monitored and controlled, but the charging cable becomes difficult to store and handle
Solution Approach 1:
The control unit function is extracted from the charging cable and placed in the charging station infrastructure instead. The charging cable itself is simplified to contain only the necessary electrical conductors and connection devices, making it lightweight and easy to handle, while the charging station provides the monitoring and control functions.
3Reliability
If identification and authorization processes are required at charging stations, then secure charging can be ensured, but the charging process becomes complex and time-consuming
Solution Approach 1:
The charging system enables self-service operation where the charging process can be initiated and controlled automatically without requiring manual identification and authorization steps from the user. The system handles authentication and control automatically, reducing the time and complexity of the charging setup process while maintaining security.
