摘要:电动汽车的出现,是科技发展和环保推行的产物。随着人们生活质量的提高,越来越多家庭开始购置汽车,导致环境环保压力日渐增加。电动汽车的推行,能够合理减缓环保压力,降低对传统能源的消耗,是汽车产业发展的重要趋势之一。现在已经有众多汽车品牌发展电动汽车,并取得良好成效。但是,汽车充电是电动汽车的重要配套服务,直接影到电动汽车的普及。因此,在研发电动汽车的同时,有必要对电动汽车交流充电桩智能控制系统进行开发设计,为电动汽车的普及发展保驾护航。

Abstract: The emergence of electric vehicles is a product of technological development and environmental protection. With the improvement of people's quality of life, more and more families have begun to buy cars, leading to increasing pressure on environmental protection. The implementation of electric vehicles can effectively alleviate the pressure on environmental protection and reduce the consumption of traditional energy. It is one of the important trends in the development of the automotive industry. There are already many car brands developing electric vehicles and achieving good results. However, car charging is an important supporting service for electric vehicles, which directly affects the popularity of electric vehicles. Therefore, while developing electric vehicles, it is necessary to develop and design the intelligent control system of electric vehicle AC charging piles to escort the popularization and development of electric vehicles.

1.市场概述 Market Overview

随着汽车智能化、电动化的发展趋势,电动汽车将成为未来汽车的主流,由此带来电动汽车充电桩的发展。充电桩中需要安装电表,来测量充电电压和充电电流以及统计充电电量,并通过RS485总线与控制模块进行通信

With the development of intelligent and electric vehicles, electric vehicles will become the mainstream of future vehicles, thus bringing the development of charging piles for electric vehicles.An electricity meter should be installed in the charging pile to measure the charging voltage and current as well as count the charging electricity, and communicate with the control module through RS485 .
