The DC single and double gun charging pile is the auxiliary equipment of the charger,which is used for slow and fast charging of electric vehicles,providing charging interface,human-computer interface and other functions,controlling the charging of electric vehicles,realizing charging on-off,card insertion charging and other operations.After secondary development,the embedded microcontroller is used as the main controller,including IC card management,charging interface management,voucher printing,online monitoring and other functions.It is a man-machine system operated by toll operators.
What are the construction requirements for DC single and double gun charging piles?Now let's have a brief understanding.
As the electric vehicle charging pile on the power distribution side of the power grid,the particularity of its structure determines that the automatic communication system has the characteristics of multiple and decentralized measuring points,wide coverage and short communication distance.With the development of the city,the network topology needs a flexible and scalable structure.Therefore,the following issues should be considered in the selection of the communication mode of the electric vehicle charging pile:
(1)Reliability of communication:the communication system shall be tested by harsh environment and strong electromagnetic interference or noise interference for a long time to keep communication smooth.(2)Project cost:under the premise of meeting the reliability,the construction cost and long-term use and maintenance cost shall be comprehensively considered.(3)Two way communication:it can not only upload information,but also release control.(4)Multi service data transmission rate:With the continuous growth of terminal traffic in the future,the communication between master stations and sub stations,and between sub stations and terminals requires higher data transmission rate to achieve multi service.(5)Flexibility and scalability of communication:Because the charging pile has many,wide and scattered control points,standard communication protocols are required.With the development of the"all IP"network technology trend and the continuous growth of power operation business,IP based business bearer should be considered,and it is required to facilitate installation,construction,commissioning,operation and maintenance.
What are the safety requirements for DC single and double gun charging piles?
(1)The substation shall be equipped with safety signs,warning boards,safety signal lights and alarm bells.(2)The warning sign of"Stop,high voltage danger"shall be hung on the safety posts outside the high-voltage distribution room and transformer room or substation.The warning sign shall face the outside of the fence.(3)The high-voltage power distribution equipment shall have obvious operation instructions,and the grounding point of the equipment shall have obvious signs.(4)There shall be obvious signs of"safe passage"or"emergency exit"indoors.
In addition,the layout design of substation and distribution equipment shall be convenient for installation,operation,handling,maintenance,testing and monitoring.High and low voltage distribution room,transformer room,capacitor room and control room shall not have any irrelevant pipes and lines.Of course,even if the technical bottleneck of the charging station is well solved,the construction of the charging station may still have problems such as site selection difficulties.New energy vehicles should be mainly urban,but the land supply in prosperous areas often exceeds demand,and the land price is high.In this regard,the government needs to make administrative policies to promote the construction of charging facilities.Electric power enterprises have inherent advantages in developing and operating electric vehicle charging stations,It is a new business for electric power enterprises to sell electric power directly to vehicles.I hope that electric power enterprises can change.
