Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the charging pile apparatus program and management-system apparatus program are tested separately, then the testing process becomes simpler, but the programs cannot be verified independently without each other
Solution Approach 1:
The patent creates a simulated charging pile apparatus that replicates the functionality of the real charging pile. This simulation allows the management-system apparatus program to be tested independently without requiring the actual charging pile, thus resolving the contradiction between simplified testing and independent verification capability
Solution Approach 2:
The patent introduces a simulated charging pile apparatus as an intermediary between the management-system apparatus and the actual charging pile. This intermediary enables independent testing of the management system while maintaining compatibility with the real charging pile through standardized communication protocols
2Reliability
If real external hardware apparatuses are used for testing, then accurate parameter data can be obtained, but the testing setup becomes large and complex
Solution Approach 1:
The patent replaces real external hardware apparatuses (power supply equipment, credit card verification apparatus) with simulated versions that generate and process parameter data software-based. This maintains data accuracy for testing while eliminating the need for large, complex hardware setups
Solution Approach 2:
The patent extracts the essential functionality of external hardware apparatuses and implements it within the simulated charging pile apparatus. This separation allows the core testing parameters to be obtained through software simulation rather than requiring physical hardware connections
3Device complexity
If parameters are hard-coded in the program codes, then the program structure remains simple, but the testing process time increases due to code modification and recompilation
Solution Approach 1:
The patent implements dynamic parameter configuration in the simulated charging pile apparatus, allowing parameters to be modified through configuration files or user interface settings rather than hard-coding. This enables rapid parameter changes during testing without requiring code modification and recompilation, significantly reducing testing process time while maintaining program structure simplicity
4Adaptability or versatility
If multiple charging protocols are supported, then the system becomes more versatile, but the preparation work for online verification becomes complex
Solution Approach 1:
The simulated charging pile apparatus is designed with universal support for multiple charging protocols (GB/T, CCS, NACS). It can dynamically adapt to different protocol requirements through configuration settings, enabling the management-system apparatus to be tested with various protocols without increasing preparation work complexity
Solution Approach 2:
The patent implements protocol switching through parameter changes in the simulated charging pile apparatus. By modifying communication protocol parameters and data formats in the simulation, the system can support multiple charging protocols while keeping the preparation work simple and standardized
Data Source
AI summary
A testing simulator for an electric vehicle includes a user interface setting a first electric vehicle communication protocol data and a second electric vehicle communication protocol data and a processing circuit storing a client main program. The user interface transmits the first electric vehicle communication protocol data to the processing circuit. The processing circuit imports the first electric vehicle communication protocol data into the client main program. The processing circuit receives a requested signal transmitted by a charging pile management-system apparatus adapted to the first electric vehicle communication protocol data in a wired manner. The processing circuit transmits a customized response signal corresponding to the requested signal to the charging pile management-system apparatus through the client main program using the first electric vehicle communication protocol data.
