AI Technical Summary

Technical Problem

Existing electric vehicle charging systems face issues with improper payment of charging fees in multi-unit buildings due to the need for installing RFID tags or wireless communication modules, leading to increased installation costs and complexity, especially in regions with high residential concentrations and underground parking lots.

Method used

An electric vehicle charging system using power line communication (PLC) that enables user identification and fee payment through a standard power outlet by employing an in-cable control box (ICCB) with a power meter, power line communication module, switch, processor, and memory, which communicates with the EVCC and payment information collection device to manage charging and payment without wireless communication.

Benefits of technology

Reduces installation costs by allowing charging control and fee payment using standard outlets, eliminating the need for RFID tags or wireless communication upgrades, and ensuring accurate billing in multi-unit buildings.

Abstract

Disclosed in the present invention are an electric vehicle charging system and method using power line communication. According to the present invention, a payment information collection apparatus connected to a plurality of power outlets is installed in a large-scale collective residential facility or commercial facility, and an in-cable control box (ICCB) (20) that controls electric vehicle charging and the payment information collection apparatus communicate with each other via a power line such that user identification information, payment information, and charged power amount, which are collected by the ICCB (20), are provided to the payment information collection apparatus to allow payment of charging fees, thereby reducing excessive costs incurred when replacing conventionally installed outlets with outlets having RFID tags or replacing the ICCB (20) with an ICCB (20) having a wireless communication function, while enabling free electric vehicle charging in general facilities.
