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.市場概述 Market Overview

隨著(zhuó)汽(qì)車智能(néng)化，電動化的(dí)發展趨勢，電(diàn)動汽車將成為未(wèi)來汽車(chē)的主(zhǔ)流(liú)，由(yóu)此(cǐ)帶(dài)來電(diàn)動(dòng)汽車充電樁(zhuāng)的(dí)發展。充電(diàn)樁(zhuāng)中需要安裝(zhuāng)電表，來測(cè)量充(chōng)電電(diàn)壓和(hé)充(chōng)電電(diàn)流(liú)以(yǐ)及統(tǒng)計充電電(diàn)量，並通過(guò)RS485總綫與(yǔ)控製模塊進行(háng)通信(xìn)。

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 .
