Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electric vehicle and charger remain in standby state during calculation time, then the charge profile can be calculated, but the equipment operation rate becomes low
Solution Approach 1:
The patent performs test charging and discharging operations during the standby calculation time T12. The vehicle controller and charge/discharge controller execute preliminary charging/discharging actions before the actual charging operation, thereby utilizing the standby period productively and increasing equipment operation rate while not delaying the scheduled charging completion time T3
2Ease of operation
If no charging/discharging operation is performed during standby time, then calculation can be completed, but user anxiety increases due to lack of visibility into operations
Solution Approach 1:
The patent implements a display unit that provides real-time feedback to the user about the test charging/discharging operations. The display shows whether the vehicle is in charging operation, test charging operation, or test discharging operation mode, and displays the state of charge SOC and power information, thereby eliminating user anxiety through transparent information provision
3Productivity
If test charging and discharging operations are performed during standby time, then equipment operation rate increases, but control safety between vehicle and charger must be ensured
Solution Approach 1:
The patent merges the vehicle controller and charge/discharge controller into a coordinated control system that jointly manages test charging and discharging operations. The controllers work together to select appropriate control commands and monitor operational parameters, ensuring synchronized and safe operation between the vehicle and charger during test operations
