The invention relates to charge port authorization for electric vehicles. A system and a method for wirelessly authorizing access to a charge port for an electric vehicle are provided. The system mayfirst establish a wireless communication link with a charging cord and then receive, from the charging cord, a wireless signal including a charging cord identifier. Upon verifying that the charging cord is authorized for use with the electric vehicle based on the charging cord identifier, a charge port door may be opened providing access to the charge port. A wireless communication link with a charging cord may be established using a challenge-response protocol like some passive entry systems. Alternatively, a wireless communication link may be established using radio-frequency identification(RFID) technology embedded in the charge port and the charging cord handle.
本公开涉及电动车辆的充电端口授权。提供了一种用于无线授权接入电动车辆的充电端口的系统和方法。该系统可以首先与充电线建立无线通信链路,且然后从充电线接收包括充电线标识符的无线信号。在基于充电线标识符验证充电线被授权与电动车辆一起使用时,充电端口门可以被打开,提供对充电端口的接入。像一些被动进入系统一样,与充电线的无线通信链路可以使用挑战‑响应协议来建立。可替代地,可以使用嵌入在充电端口和充电线把手中的射频识别(RFID)技术来建立无线通信链路。
