Industrial Switches in the Scheme of New Energy Vehicle Charging and Changing Power Station

With the deployment and implementation of the new energy strategy, the number of new energy vehicles continues to rise. The supporting new energy vehicle charging and changing facilities have taken the lead in construction, and will gradually form an electric vehicle charging and changing system combining charging piles, charging stations, power stations and other facilities. In order to implement the Guiding Opinions of the General Office of the State Council on Accelerating the Promotion and Application of New Energy Vehicles, scientifically guide the construction of new energy vehicle charging infrastructure, and promote the healthy and rapid development of the new energy vehicle industry, the National Development and Reform Commission, together with the National Energy Administration, the Ministry of Industry and Information Technology and the Ministry of Housing and Urban Rural Development, has organized the preparation of the Guidelines for the Development of Electric Vehicle Charging Infrastructure. The construction of new energy vehicle charging infrastructure will be carried out on a large scale. According to the data of China Charging Alliance, from January to June 2022, the increment of charging infrastructure will be 1.301 million units, with a year-on-year growth of 388.1%. The construction of charging infrastructure is speeding up.

However, the IT resources of traditional charging stations are built according to peak business, which wastes a lot of resources; At the same time, the waiting time for charging also greatly reduces the travel efficiency of car owners. Therefore, charging users need a highly reliable charging experience guarantee, and innovative new energy vehicle charging and changing power station services emerge as the times require. In the future, the charging infrastructure cannot be separated from the collaborative support of new technologies such as big data, 5G and Industrial Switch communication.

Characteristics of new energy vehicle charging and changing power station scheme

The overall scheme adopts modular design to facilitate the later maintenance and expansion between subsystems. The backbone LAN adopts gigabit optical fiber ring network to enhance the overall stability and reliability of the system;

The core switch of the centralized monitoring center adopts a rack type three-layer industrial switch, which forms an optical fiber ring network with each subsystem, and is connected to the office network and the monitoring screen at the same time. The data and on-site video of each subsystem converge, and the management personnel can view the on-site working status in real time only in the monitoring center;

Ring network switch and monitoring center are used to form an optical fiber ring network in each power exchange station. The ring network switch is divided into three groups of VLANs to communicate the barrier gate, video and power exchange device independently with the centralized monitoring center and local processing unit. Reasonably use the forwarding resources of the industrial switch, and each VLAN will not interfere with each other to ensure smooth video transmission and accurate control data;

The automatic power exchange device adopts wireless communication mode. The industrial wireless AP covers the whole site with WIFI, and the battery is transferred to RGV. The power exchange device adopts wireless connection mode;

The centralized charging system is also connected to the monitoring center by ring network switch, which is connected to the Ethernet data such as the electric energy meter, relay protection and data collector in the charging room;

The environmental monitoring system in the charging room uses the industrial serial port server to connect the serial port bus devices such as the on-site fan, temperature and humidity sensor, heat dissipation, and access control, so as to convert the RS-232/422/485 serial port into TCP/IP and connect it to the charging room ring network switch. This serial port service supports VX-Bus, virtual serial port, TCP, UDP, Modbus/TCP and other working modes, enabling design engineers to have flexible implementation solutions;

For each charging station, a 5G+WIFI router is used. The on-site WIFI coverage is provided for the handheld terminal staff, and can also be used for system debugging. The 5G function uploads the data to the cloud platform. Customers can make an appointment for power change service and check the progress and status of car power change in real time through the mobile phone APP. It can also be used for remote payment. Payment can be completed only on the mobile phone.

We actively responded to the national zero carbon call, fully invested in innovative new energy communication services, and combined with the industrial switches, designed a comprehensive communication system scheme for the new energy vehicle charging and changing power station to solve the pain point of new energy vehicle charging, which can ensure the safety of data transmission between the systems of the power station; The monitoring center can not only master the real-time working state of the power supply system and the charging and changing system and the current environment of the power station, but also timely send control instructions to the charging and changing system, the cooling system, and the temperature regulation system to ensure that the charging and changing process is safe, smooth, effective, and fast.

At the same time, the charging and changing scheme of new energy vehicles can realize the scientific management mode of networking and intelligence, making the operation of the charging pile more stable, reliable, and the management more simple and convenient. At the same time, because the charging platform can realize intelligent management, it can greatly save the use cost under the condition of ensuring stability, greatly promote the commercial application and promotion of charging piles, and realize vehicle management, amount settlement and analysis and statistics of various business data.
