介绍一种基于STC8单片机和IC卡支付对电动汽车的充电系统,其特点在于增加电费计量,利用车载家用充电装置充电,因充电功率小、成本低、利于推广,故利用单片机的多个串行接口分别采集电能表的用电量、RFID射频IC卡射频模块提供收费、串行TM1638驱动数码管显示和键盘指令输入等。本系统可以借助电网波谷充电,降低大功率充电对电网负荷的冲击[1].
This paper introduces a charging system for electric automobile based on STC8 single chip computer and IC payment card.it aims to are to increase the electricity charge measurement and charge with the on-board household charging device.Because of the low charing power,low cost and its popularization,It applys multipled serial interfaces of single chip to collect the power consumption of the electricity meter,charges by RFID card and IC card,which driving digital to dasplay byserial TM1638 and usingkeyboardcommandsetc.This system can reduce the impact on grid load by means of grid trough charging.
