Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed configuration data set is stored in the charging station, then the charging control module can control charging processes, but the charging station lacks flexibility and has limited usability
Solution Approach 1:
The patent implements dynamic configuration by allowing the charging station to retrieve different configuration data sets based on time specifications. The multiplex module determines appropriate configuration parameters dynamically rather than using fixed values, enabling the charging station to adapt its behavior (charging currents, energy transfer limits, billing parameters) according to temporal conditions while maintaining a relatively simple hardware architecture.
2Adaptability or versatility
If multiple configuration data sets are stored locally in the charging station, then flexibility increases, but device complexity and memory requirements increase
Solution Approach 1:
The patent introduces a backend system as an intermediary that stores multiple configuration data sets and provides them to the charging station as needed. The multiplex module in the backend system acts as a mediator that receives configuration requests, determines the appropriate configuration data set based on time specifications, and transmits it to the charging station. This approach allows the charging station to have access to multiple configurations without storing them all locally, reducing memory requirements while maintaining flexibility.
3Ease of operation
If configuration parameters are fixed in the charging station, then the system is simple to operate, but real-time adjustments to charging parameters cannot be made
Solution Approach 1:
The patent implements periodic configuration updates where the charging station periodically requests configuration data sets from the backend system based on time specifications. The multiplex module determines whether configuration parameters have changed based on time conditions and transmits updated configurations accordingly. This periodic update mechanism allows the system to maintain simple operation during charging while automatically adapting to real-time changes in configuration requirements.

AI summary
Charging system for electric vehicles including a backend system and a charging station. The charging station includes a charging control module to control a charging process between a charging point of the charging station and an electric vehicle connectable to the charging point at least based on a configuration data set comprising a charging configuration parameter. The backend system includes a multiplex module connectable to a configuration memory module. The configuration memory module stores a plurality of time dependent configuration data sets. The multiplex module determines a time dependent configuration data set upon receipt of a configuration request message emitted by the charging station based on a time specification of the configuration request message. The multiplexing module is configured to cause a transmitting of the determined configuration data set to the charging station. The charging control module configured to control the charging process based on the received configuration data set.
