Solution Overview
Problem
Current charging piles face issues with users occupying spaces for extended periods after charging is complete, leading to wasted parking and charging spaces, hindering the use by other customers.
Innovation Solution
A time delay toll system that includes a charging state inspection module to detect voltage changes, a parking detection module to track vehicle presence, and a microprocessor to calculate and deduct charges and time delay expenses from users, encouraging timely departure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users are allowed to stay at charging piles after charging is complete, then user convenience is improved, but charging pile availability deteriorates
Solution Approach 1:
The system changes the pricing parameter dynamically based on time. After charging completion, a grace period with no additional charge is provided, but after this period expires, time delay expenses are charged. This parameter change (from free to charged) motivates users to leave while maintaining initial convenience
Solution Approach 2:
The system provides feedback to users about the charging completion status and remaining grace time. The microprocessor notifies users when charging is complete and calculates time delay expenses, creating a feedback loop that guides user behavior toward timely departure while maintaining availability
2Productivity
If users are encouraged to leave quickly after charging, then charging pile availability is improved, but user satisfaction may deteriorate
Solution Approach 1:
The system performs preliminary action by notifying users in advance when charging is complete and providing a grace period before time delay charges begin. This preliminary notification and grace period prevent user dissatisfaction while still encouraging timely departure to maintain availability
Solution Approach 2:
The grace period acts as a cushion that absorbs the potential negative impact of encouraging quick departure. Users have a buffer period to leave without penalty, cushioning against dissatisfaction while still promoting pile availability
3Productivity
If time delay expenses are charged to users, then charging pile availability is improved, but system complexity deteriorates
Solution Approach 1:
The microprocessor automatically detects charging completion through voltage detection, calculates the time delay expenses, and manages the billing process without human intervention. This self-service approach handles the complexity internally while presenting a simple interface to users and maintaining high availability

AI summary
Invention enclosed herein discloses a time delay toll system for charging piles, which can promote an electric automobile user to leave as early as possible and/or settle accounts as quick as possible after the charging is completed, improve the availability factor of the charging piles and parking stalls, and thereby increasing an efficiency of operation of the charging piles. The time delay toll system comprising: a charging state inspection module, which is configured to detect a magnitude of each communication cable of a plurality of communication cables installed in the charging piles, and send the magnitude of the voltage to a microprocessor; a parking detection module, which is installed on a parking stall, and is configured to detect whether there is an automobile on said parking stall; a microprocessor, which is configured to determine whether the charging of said automobile is competed according to a magnitude of a voltage of a communication cable associated with said automobile, if said charging is completed, notify a timer to reckon by time to generate time elapse data associated with said charging, which is a time period from said automobile driving in the parking stall for charging to leaving the parking stall when the charging is completed; and a fee deduction module, which is configured to calculate a charge expense and a time delay expense, and to deduct the said charge expense and said time delay expense from a user fund previously established for an owner of said electric automobile. A method that adopts this time delay toll system for charging piles is also disclosed.
