Abstract: Electric Vehicles have been regarded as the development trend of the next generation of vehicles. As the "station" of electric vehicles, the comprehensive development of charging pile construction will provide a huge market. At the same time, the price of refined oil rises faster than it falls, so the car owners will bear higher and higher oil prices. Electric vehicles can replace part of the consumption of gasoline and diesel, reducing this part of the cost. There is no doubt that the charging pile is the terminal market promoted by the new energy strategy. If we can seize the opportunity now, it will be of great benefit.

 

1.市場(chǎng)概述 Market Overview

　　由于電動(dòng)汽車每天需要補(bǔ)充大量電能，經(jīng)營(yíng)充電站就可以獲得巨大的充電服務(wù)收益。相對(duì)于加油站，電能比較安全和方便，可在各地大量安裝設(shè)置充電站。根據(jù)投資規(guī)模，小到社區(qū)慢速充電樁，大到公路快速充電站，單站經(jīng)營(yíng)，組網(wǎng)經(jīng)營(yíng)均可。

　　As electric vehicles need to supplement a large amount of power every day, the operation of charging station can obtain huge charging service revenue. Compared with the gas station, the power is more safe and convenient, and a large number of charging stations can be installed in various places. According to the scale of investment, from small to community slow charging pile, to highway fast charging station, single station operation, network operation also can be.

 

2.DJSF1352直流電測(cè)儀表介紹 DJSF1352 DC Power Meter Introduction

　　DJSF1352-RN導(dǎo)軌式直流電能表帶有雙路直流輸入，主要針對(duì)直流充電樁應(yīng)用場(chǎng)合而設(shè)計(jì)，該系列儀表可測(cè)量直流系統(tǒng)中的電壓、電流、功率以及正反向電能等。在實(shí)際使用現(xiàn)場(chǎng)，即可計(jì)量總電能，又可計(jì)量規(guī)定時(shí)間段內(nèi)的電能。檢測(cè)的結(jié)果既可用于本地顯示，又能與工控設(shè)備、計(jì)算機(jī)連接，組成測(cè)控系統(tǒng)。儀表可具有紅外通訊接口和RS-485通訊接口，同時(shí)支持Modbus-RTU協(xié)議；可帶繼電器報(bào)警輸出和開關(guān)量輸入功能；根據(jù)不同要求，通過(guò)儀表面板按鍵，對(duì)變比、報(bào)警、通訊進(jìn)行設(shè)置；具有開關(guān)量事件記錄（Modbus協(xié)議）電壓電流功率最大值、最小值記錄功能。

　　

　　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.
