Underground EV Charging Pole Reservation Control for Easier Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underground power supply equipment can hinder vehicle parking due to protruding charging poles, reducing user convenience, especially when multiple parking slots are involved.
Innovation Solution
A server system that manages parking slots and power supply equipment, prioritizing reservations for slots with unreserved neighboring slots, allowing the power supply equipment to be stored underground until needed, and remotely controlling the equipment to protrude only when required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the charging pole is stored under the ground, then the parking space utilization is improved, but the user convenience deteriorates when the charging pole protrudes and interferes with parking
Solution Approach 1:
The server performs preliminary reservation actions to determine which parking slots will be occupied before vehicles arrive. Based on this advance information, the control device pre-positions the charging pole in the protruding state for reserved slots, ensuring readiness before the vehicle arrives and preventing interference with non-reserved slots where the pole remains retracted.
Solution Approach 2:
The system implements feedback through the reservation system, where the server communicates reservation status to the control device, which then adjusts the charging pole position accordingly. This closed-loop control ensures the pole is only protruding when a vehicle has reserved the slot, eliminating unnecessary protrusions that would interfere with parking.
2Reliability
If the charging pole protrudes from the ground, then the power supply function is improved, but the ease of parking deteriorates due to interference with vehicle access
Solution Approach 1:
The charging pole transitions from a static structure to a dynamic one that can change its position between retracted and protruding states. The control device actuates the pole to protrude only when a reservation is confirmed for that slot, and retract it when no reservation exists, optimizing both power supply availability and parking accessibility based on real-time需求的.
Solution Approach 2:
The system uses the reservation information to pre-position the charging pole in the protruding state before the vehicle arrives at the parking slot. This preliminary action ensures the power supply function is ready when needed while avoiding premature protrusion that would interfere with other vehicles' parking maneuvers.
3Quantity of substance
If multiple parking slots are managed with underground power supply equipment, then the system capacity is improved, but the complexity of managing protrusion states increases
Solution Approach 1:
The server acts as an intermediary between the reservation system and the multiple control devices managing different parking slots. It centralizes the reservation information and distributes relevant instructions to each control device, allowing independent management of each charging pole while maintaining coordinated system-wide operation through the mediating server.
Solution Approach 2:
The system divides the management of multiple parking slots into independent, modular control units. Each parking slot has its own control device that independently manages its charging pole based on reservation information received from the server, allowing scalable expansion without increasing overall system complexity.

AI summary
A power supply equipment provided for each of parking slots is configured to be able to be stored under a ground, and is configured to supply power to a vehicle parked in a corresponding parking slot with the power supply equipment protruding from the ground. A server that manages each of the parking slots and the power supply equipment is configured to receive a reservation request that specifies a reservation start time of the parking slot. The server is configured to reserve, from a vacant slot, out of the parking slots, that is unreserved at the reservation start time, a parking slot with a neighboring parking slot on at least one side unreserved at the reservation start time with priority over a parking slot with neighboring parking slots on both sides reserved at the reservation start time, when the server receives the reservation request.
