Acrel Din Rail Dc Power Meter Applicated In Hongkong Charging Pile Company

摘要：電動汽車的出現(xiàn)，是科技發(fā)展和環(huán)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(huán)境環(huán)保壓力日漸增加。電動汽車的推行，能夠合理減緩環(huán)保壓力，降低對傳統(tǒng)能源的消耗，是汽車產業(yè)發(fā)展的重要趨勢之一。現(xiàn)在已經有眾多汽車品牌發(fā)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(fā)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(tǒng)進行開發(fā)設計，為電動汽車的普及發(fā)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(fā)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(fā)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(tǒng)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 .

2.DJSF1352直流電測儀表介紹 DJSF1352 DC Power Meter Introduction

DJSF1352-RN導軌式直流電能表帶有雙路直流輸入，主要針對直流充電樁應用場合而設計，該系列儀表可測量直流系統(tǒng)中的電壓、電流、功率以及正反向電能等。在實際使用現(xiàn)場，即可計量總電能，又可計量規(guī)定時間段內的電能。檢測的結果既可用于本地顯示，又能與工控設備、計算機連接，組成測控系統(tǒng)。儀表可具有紅外通訊接口和RS-485通訊接口，同時支持Modbus-RTU協(xié)議；可帶繼電器報警輸出和開關量輸入功能；根據不同要求，通過儀表面板按鍵，對變比、報警、通訊進行設置；具有開關量事件記錄（Modbus協(xié)議）電壓電流功率大值、小值記錄功能。

DJSF1352 has double DC input channels, mainly designed for DC charging piles, solar , this series of meters can measure the voltage, current, power and forward and reverse energy and so on in the DC system.The actual use of the site, you can measure the total power, but also measure the energy within a specified period of time. The test results can be used for local display, but also with industrial control equipment, computers to form a measurement and control system.

The meter can have infrared communication interface and RS-485 communication interface, and

supports Modbus-RTU protocol .The meter can have relay alarm output and digital input function;You can set the ratio, alarm, and communication through the meter panel keys according to different requirements.The meter can have event recording of switch (Modbus protocol), maximum and minimum value recording function of voltage and current power.
