摘要：電動汽車的出現，是科技發展和環保推行的產物。隨著人們生活質量的提高，越來越多家庭開始購置汽車，導致環境環保壓力日漸增加。電動汽車的推行，能夠合理減緩環保壓力，降低對傳統能源的消耗，是汽車產業發展的重要趨勢之一。現在已經有眾多汽車品牌發展電動汽車，并取得良好成效。但是，汽車充電是電動汽車的重要配套服務，直接影到電動汽車的普及。因此，在研發電動汽車的同時，有必要對電動汽車交流充電樁智能控制系統進行開發設計，為電動汽車的普及發展保駕護航。

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.市場概述 Market Overview

隨著汽車智能化、電動化的發展趨勢，電動汽車將成為未來汽車的主流，由此帶來電動汽車充電樁的發展。充電樁中需要安裝電表，來測量充電電壓和充電電流以及統計充電電量，并通過RS485總線與控制模塊進行通信。

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 .
