Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If EV charging is allowed without control, then charging convenience is improved, but power demand concentration increases causing power shortages
Solution Approach 1:
The system performs preliminary actions by receiving charging reservation information in advance, predicting required power before charging occurs, and determining control strategies ahead of time. This allows the system to prepare for potential power demand concentration and implement preventive control measures, ensuring both charging convenience and power supply stability.
Solution Approach 2:
The system implements feedback by continuously monitoring predicted required power against predicted suppliable power, and adjusting charging control decisions based on this comparison. The determination part uses the feedback from power predictions to decide whether to approve or adjust charging reservations, dynamically balancing convenience and reliability.
2Reliability
If charging reservation control is implemented, then power demand concentration is reduced, but system complexity increases
Solution Approach 1:
The control system is segmented into distinct functional parts: a reception part for receiving reservations, a required power prediction part for calculating demand, a determination part for decision-making, and a control part for execution. This segmentation allows each component to perform a specific function, making the overall complex system manageable and maintainable while achieving power supply stability.
3Reliability
If power prediction and control processing is performed, then power demand smoothing is achieved, but processing time increases
Solution Approach 1:
The system performs power predictions and control determinations in advance before charging actually occurs. By predicting required power and making control decisions beforehand, the system smooths power demand without causing delays during the actual charging process, minimizing processing time impact on users.

AI summary
A charging reservation control device includes: a reception part which receives charging reservation information for a plurality of electric transportation devices and a first prediction value that is a prediction value of suppliable power in a power source; a required power prediction part which calculates a second prediction value that is a prediction value of electric power required for charging the plurality of electric transportation devices on the basis of the charging reservation information; a determination part which determines whether to implement control on the basis of the first prediction value and the second prediction value; and a control part which implements, when the determination part determines that the control is performed, the control so that a concentration of power demand relating to charging of the electric transportation device is reduced.
