The function of the DC single and double gun charging pile is similar to that of the fuel dispenser in the gas station.It can be fixed on the ground or on the wall,installed in public buildings(public buildings,shopping malls,public parking lots,etc.)and residential parking lots or charging stations,and can charge various electric vehicles according to different voltage levels.The input end of the DC single and double gun charging pile is directly connected to the AC power grid,and the output end is equipped with a charging plug to charge electric vehicles.The general charging pile provides two charging modes:conventional charging and fast charging.People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile,and print the corresponding charging mode,charging time and cost data.The display screen can display the charging amount,cost,charging time and other data.
The DC single and double gun charging pile directly charges the electric vehicle,with large power and fast charging speed,but high cost.It is connected to the AC power grid,and the output is adjustable DC,which can directly charge the electric vehicle power battery.DC single and double gun charging pile adopts three-phase four wire system for power supply,with large power and wide range of output voltage and current regulation,which can meet the requirements of rapid charging.When the power is above 30kW,it generally takes only 1-2 hours to fully charge,which has the advantages of fast charging speed,high cost and fast charging.
The DC single and double gun charging pile belongs to the distribution network side,and its communication mode is often considered together with the distribution network automation.Communication is an important and difficult point of distribution network automation.Different communication methods can be used in different regions and conditions.For DC single and double gun charging posts of electric vehicles,there are mainly two communication modes:wired and wireless:
(1)Wired mode.The wired mode mainly includes wired Ethernet(RJ45 cable,optical fiber)and industrial serial bus(RS485,RS232,CAN bus).The main advantages of wired Ethernet are reliable data transmission and large network capacity,while the disadvantages are complex wiring,poor scalability,high construction cost and poor flexibility.Industrial bus(RS485,RS232,CAN bus)has the advantages of reliable data transmission and simple design,but its disadvantages are complex network layout,poor scalability,high construction cost,poor flexibility and low communication capacity.
(2)Wireless mode.The wireless mode mainly adopts the data access services of mobile operators,such as GPRS,EVDO,etc.Using the operator's data business,it is necessary to connect the electric vehicle charging pile,the internal equipment of the power grid,to the operator's data network,and it is necessary to pay expensive monthly rent and annual fees.With the increase of the number of charging piles,the cost will become larger and larger.At the same time,data security and network reliability are restricted by operators,which is not conducive to the safe operation of equipment;Secondly,the access bandwidth of operators belongs to shared bandwidth.When a large number of devices are accessed in a local area,the access reliability and average bandwidth of each user will become worse,which is not conducive to its intensive access and data transmission of large amounts of data.
