Abstract

The invention discloses a time delay toll system for charging piles, which can promote the electric automobile user to leave as early as possible or settle accounts as early as possible after the charging is end, improve the availability factor of the charging piles and parking stalls, and increase an efficiency of operation of the charging piles. The system includes: the charging state inspection module, which is configured to detect the magnitude of voltage of the communication cables of the charging piles, and send the magnitude of voltage to the microprocessor; the parking detection module, which is installed on the parking stall, and is configured to detect whether has an automobile on this parking stall; the microprocessor, which is configured to determine whether the charging is end according to the magnitude of voltage, if yes, then notify the timer to reckon by time, and send the module of deducting fees the time that the automobile stayed from the time beginning to the car'"'"'s leaving; the module of deducting fees, which is configured to calculate the charge expense and time delay expense, and is configured to deduct the said charge expense and time delay expense from the user'"'"'s fund. The method that adopts this time delay toll system for charging piles is also provided.
