1. Industry background
Smart green travel is a catalyst for promoting the deployment of new energy strategies, and it is also one of the important strategies for building a well-off society in an all-round way as a future development goal. In 2014, the General Office of the State Council issued the “Notice of the State Council on Printing and Distributing the Development Plan for Energy Saving and New Energy Automobile Industry (2012-2020)” (Guo Fa [2012] No. 22), which pointed out: Facility development planning and technical standards. Improve the construction of charging facilities standard system, formulate and implement development plans for new energy vehicle charging facilities, encourage social capital to enter the field of charging facilities construction, actively utilize existing sites and facilities in the city, promote the construction of charging facilities projects, and improve the layout of charging facilities.
IDC estimates that China's new energy vehicle sales in 2020 will be about 1.16 million, and it is expected to reach 5.42 million in 2025. The number of electric vehicles in the country has exceeded 5 million, including more than 700,000 electric buses, taxis, and sanitation workers' rotating cars, and 4.3 million electric business or private cars. According to the amount of electric vehicle power distribution infrastructure, more than 12,000 centralized charging stations and 4.8 million decentralized charging piles need to be added to meet the charging demand of more than 5 million electric vehicles nationwide.
2. Solutions
Charging pile sites provide charging and battery swapping services for new energy electric vehicles. It is necessary to network these charging facilities and build a charging intelligent service system to ensure a good user experience and operational efficiency.
The charging intelligent service system needs to provide real-time monitoring of charging power, geographical location of charging piles, local data transmission of charging piles, and charging fee statistics functions. Automatic deduction. The charging pile has the function of automatic fault detection, automatically notifies engineers for on-site maintenance for faults, and has the function of remote automatic upgrade.
Scheme 1 centralized charging pile:
This type of charging pile system can be connected by wired local area network, providing external network connection services or special public network connection services through industrial routers to connect to the charging intelligent service platform, and finally establish a connection with the monitoring operation center of the charging operation company to realize charging facilities. Two-way data transfer to and from the monitoring operations center.
Scope of application: It is suitable for the construction of charging infrastructure in public service fields such as public transportation, rental, logistics, sanitation and expressways.

Option 2 Distributed charging pile:
Use industrial-grade wireless data terminal DTU for networking. The charging pile control board is connected to the DTU through the serial port, and the wireless DTU automatically dials up and connects to the network through the operator's GPRS/Cat-1/4G network, and establishes a connection with the monitoring operation center of the charging operation company, thereby establishing a connection between the charging facility and the monitoring operation center. data transmission channel.

3. Advantages of the scheme
Data sharing, convenient and fast
Real-time monitoring of power usage and billing statistics, synchronous upload, and real-time feedback of charging parameters during user charging to customers. The location of the charging pile is displayed in real time, guiding the driver to quickly find the nearby charging pile. The current usage and operating status of the charging pile are uploaded in real time, updated synchronously, and notified to customers in a timely manner.
Safe, reliable and efficient operation
The remote update function can realize the remote upgrade function of the charging pile control system, ensure that the function of the charging pile control system is updated, and the BUG repair is faster. In response to the unexpected failure of the charging pile, it is automatically detected and uploaded to the service platform in time. The platform actively calls nearby maintenance personnel to maintain the equipment, and the payment is convenient and can be paid with one click.
4. Industry application
It is suitable for charging all kinds of electric vehicles and new energy vehicles. The equipment can be used in residential areas, shopping malls, near gas stations, highway service areas and other occasions suitable for installing charging piles.
Scope of application: Distributed charging piles.
