A supply device with a control system that compares the required power of vehicles with the available power and adjusts distribution accordingly, notifying vehicles of insufficient supply and calculating allocated power when demand exceeds supply, while also considering vehicle size and battery state of charge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power is distributed to multiple vehicles traveling in the power supply lane concurrently, then the power supply capacity is utilized more effectively, but the balance between power demand and power supply becomes difficult to maintain due to individual variations in supply capability and vehicle conditions
Solution Approach 1:
The control device receives required power information from each vehicle, compares it with the suppliable power, and adjusts the distribution of supply power accordingly. This feedback mechanism ensures that power distribution dynamically adapts to changing vehicle demands and supply conditions, maintaining balance while utilizing total supply capacity effectively
Solution Approach 2:
The system transitions from static power distribution to dynamic adjustment based on real-time vehicle conditions and supply capabilities. The control device continuously monitors required power from each vehicle and adjusts the allocated power distribution, enabling the system to adapt to individual variations in vehicle demand and ground-side supply changes
2Productivity
If the control device adjusts power distribution based on vehicle requirements and supply capabilities, then power allocation becomes more optimized, but the complexity of the control system increases due to continuous monitoring and calculation requirements
Solution Approach 1:
The control device performs preliminary comparison and calculation of required power versus suppliable power before actual power distribution. By pre-assessing power demands from multiple vehicles and determining optimal allocation in advance, the system simplifies the real-time control process while achieving optimized power distribution
Solution Approach 2:
The control device acts as an intermediary between the power supply system and multiple vehicles, centralizing the complex calculation and decision-making functions. This intermediary role allows the system to manage power distribution complexity in one location while presenting simplified interfaces to both the power supply and vehicle systems
3Loss of information
If vehicles are notified in advance of insufficient supply power, then the driver can make informed decisions about power availability, but the system requires additional communication infrastructure and processing
Solution Approach 1:
The control device sends notifications to vehicles about insufficient supply power based on the comparison between required and suppliable power. This feedback loop provides essential information to drivers while using existing communication channels between the control device and vehicles, minimizing additional infrastructure requirements

AI summary
A supply device includes a power transmission device that has a primary coil provided on a road and transmits power to a vehicle traveling on a road in a non-contact manner, and a ground-side control device that controls the power transmission device, wherein the control device compares the required power of the vehicle traveling on the power supply lane provided with the primary coil with the suppliable power supplied by the power transmission device, adjusts the distribution of the supply power from the ground side to the vehicle based on the comparison result, and notifies the vehicle that the supply power from the ground side is insufficient when the suppliable power is smaller than the required power.
