Patent ID: 11780338

Abstract:
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.
