电动汽车充电桩属于配电网侧,其通信方式往往和配电网自动化一起综合考虑。通信是配电网自动化的一个重点和难点,区域不同、条件不同,可应用的通信方式也不同,具体到电动汽车充电桩,其通信方式主要有有线方式和无线方式。1、有线方式有线方式主要有:有线以太网(RJ45线、光纤)、工业串行总线(RS485、RS232、CAN总线)。
Electric vehicle charging pile belongs to the distribution network side, and its communication methods are often considered together with distribution network automation. Communication is a key and difficult point in the automation of distribution network. Different regions have different conditions and applicable communication methods are different. Specifically, there are mainly wired and wireless communication modes for electric vehicle charging piles. 1, Wired Wired Ways mainly include: wired Ethernet (RJ45 cable, optical fiber), industrial serial bus (RS485, RS232, CAN bus).
