Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If comprehensive testing of storage and charging functions is performed, then reliability is improved, but testing complexity increases
Solution Approach 1:
The testing system is divided into multiple independent testing modules: communication function testing module, energy storage function testing module, and charging function testing module. Each module independently tests specific functions, allowing comprehensive testing while maintaining modularity and reducing overall system complexity.
Solution Approach 2:
The communication function testing is performed first as a preliminary step before energy storage and charging function testing. This preliminary action ensures that communication pathways are established and functional before more complex operational testing begins, streamlining the overall testing process.
2Adaptability or versatility
If multiple charging modes are tested, then adaptability is improved, but testing time increases
Solution Approach 1:
Different charging modes (AC-DC converter charging, energy storage apparatus charging, and combined charging) are tested in periodic sequences through the charging function testing module. This structured periodic testing approach efficiently covers multiple charging scenarios without requiring separate testing procedures for each mode, reducing overall testing time while maintaining comprehensive coverage.
Data Source
AI summary
A testing method and a testing system for a storage and charging system are disclosed. A tester acquires first charging data about that an energy management system instructs an AC-DC converter to charge an energy storage apparatus in a case that the remaining power of the energy storage apparatus is less than or equal to a first threshold, and determines whether an energy storage function of the storage and charging system is normal; the tester acquires second charging data about that the energy management system controls the AC-DC converter and/or the energy storage apparatus to charge a device when the device is connected to the charging conversion apparatus, and determines whether a charging function of the storage and charging system is normal. The energy storage function and the charging function are tested when a communication function between a battery management unit and the energy management system passes testing.
