摘要：電動汽車，一直被看做是下一代汽車的發展趨勢。作為電動汽車的“加油站”，充電樁建設的全方面開展，無疑會提供巨大的市場。同時，成品油價格上漲速度高于下降速度，終車主承受的是越來越高的油價，電動車可以代替部分汽油柴油的消耗，降低了這部分成本。毋庸置疑充電樁是新能源戰略推進的終端市場，如能在現在搶占先機，對資本的盈利有較大好處。

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.市場概述 Market Overview

由于電動汽車每天需要補充大量電能，經營充電站就可以獲得巨大的充電服務收益。相對于加油站，電能比較**和方便，可在各地大量安裝設置充電站。根據投資規模，小到社區慢速充電樁，大到公路快速充電站，單站經營，組網經營均可。

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.

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中的電壓、電流、功率以及正反向電能等。在實際使用現場，即可計量總電能，又可計量規定時間段內的電能。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。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.
