Cui Baoqian and Xu Jianzhong, a researcher of Hefei Power Supply Company in the 10th issue of “Electric Technology” in 2015, pointed out that with the continuous expansion of global dynamic crisis, all countries will be depressed by teachers. Pinay escortThe vision of carbon economic development has been directed to the electric vehicle industry. However, the development of electric vehicles should be coordinated simultaneously with the development of charging and electrical facilities, so there is a very important practical meaning for the design and key technologies of charging and electrical equipment. Based on the project that Sugar daddy is actually participating, the author discusses dual-directional interaction between dual-charging vehicle energy and distribution network.
1 Overview of dual-direction charging bus
Now, my country has developed or has probably implemented and constructed charging buses and charging stations. The service goals of these two charging facilities are different. Charging stations are used for fast charging of electric vehicles, and the charging time is relatively short; while charging time is mainly used for slow charging of electric vehicles, and the charging time is relatively long.
These two charging facilities have their own advantages in charging efficiency, environmental request, etc., and are specifically Sugar babyWhen choosing, it should be fairly adopted based on actual conditions. The floor area occupied by charging space is smaller and the cost of management is relatively low. Generally, in the city’s parking lot, the Pinay escort is constructed in the area to meet the charging needs of electric vehicles. At the same time, the charging mode is a slow charging mode. The current is smaller and the safety function is higher, which can extend the life of the electric car battery to a certain level.
Dual charging means a DC charging facility that implements dual communication between the vehicle loading battery system and the photovoltaic network under the control of the microcomputer.
2 Analysis of relevant technical indicators for dual-direction charging and mobile application systems
2.1 Technical indicators for integrated monitoring platforms
The charging and mobile installation is mainly evacuated in parking lots, small areas and other areas, and the locations are relatively evacuated. Charging and mobile installation is Sugar daddy The quantity of Escort is relatively large. Please find the performance of the data communication service for the Escort manila comprehensive monitoring platform. At the same time, for the convenience and real-time display of charging status, it integrates passers-by. The monitoring platform must have a human interface, which displays the relevant information of each state of the charging mode, the information output from the cost management system, and the relevant charging parameters customized by users through web methods in diagrams, tables and other situations, and uses the relevant inquiry and manipulation of the user. To guarantee the system letterThe comprehensive monitoring platform must have the effectiveness of information security isolation to ensure the security of the system’s network security.
In addition, other technical indicators on the platform are as follows: Have the authors read the logic? , Is the system’s application life beautiful and good to sing? Beautiful…singing…sweet? The sound is sweet, it takes 10 years, the annual application rate of the system is not less than 99.98%, and the faultless operation time (MTBF) of various equipment of the main site must be 40,000 hours [1].
2.2 Technical indicators for charging buses for dual-directional charging buses
Double-directional charging buses are fixed outside the electric car and are connected to the Internet Sugar baby, providing DC charging services for non-carrier electric vehicle power batteries. The design of the dual-direction charging port is the focus and key of this project. The dual-directional charging channel design determines the charging and discharging power of 1 “Escort manila”. As one of the background characters, at the 2kW, the maximum voltage value of the battery terminal is 500V, and the maximum current value during charging or discharging is 25A, and the power factor must be 0.99. The charging object of the dual-directional charging bus is a dielectric battery. The output current of the dual-direction charging rod is DC, and the output voltage meets the charging object’s Escort pool standard request. Its designed charging method is divided into two different methods: manual and automatic, automatic charging and chargingThe system under the form must receive control of the energy quality control system, and the system under the manual charging mode must be based on the charging parameters set by the user.
