As a green means of transportation with broad development prospects, the popularization of electric vehicles will be extremely rapid in the future, and the future market prospect is also extremely huge. In the context of the global energy crisis and serious environmental crisis, the Chinese government actively promotes the application and development of new energy vehicles. As an important supporting infrastructure necessary for the development of electric vehicles, the charging/changing station has very important social and economic benefits. A campaign to build an electric vehicle charging/changing station has been launched nationwide. The overall system consists of four parts: electric vehicle charging pile, concentrator, battery management system (BMS), and charging management service platform.

After the completion of charging piles in some places, operation and maintenance become a problem. On the one hand, the number of urban public charging facilities is small, and the distribution is uneven and unreasonable; On the other hand, the management service platforms of the charging infrastructure construction and operation units have not yet achieved interconnection, nor has there been a unified, open and convenient payment platform, which has caused great inconvenience to charging infrastructure users. In addition, in the development process of new energy vehicle industry, there is a widespread problem of focusing on vehicles rather than charging infrastructure. In addition, the national early support policy is mainly aimed at new energy vehicles and does not cover charging facilities. Except for a few cities, most cities have no local subsidies. "This leads to the coexistence of vehicles without piles and piles without vehicles." Moreover, charging infrastructure construction involves urban planning, construction land, distribution network construction and transformation, property management and other aspects, and it is necessary to coordinate multiple competent departments and relevant units in the implementation process.

DC type: a) Power input voltage of charging pile (plug): three-phase four wire 380VAC ± 15%, frequency 50Hz ± 5%; b) The charging pile (plug) shall meet the charging object; c) The output of the charging pile (plug) is DC, and the output voltage meets the battery system requirements of the charging object; d) Zui's large output current meets the charging requirements of battery system 1C of the charging object, and is downward compatible; e) The charging mode can be divided into conventional and fast charging modes. The conventional charging mode is 5-hour charging mode, and the fast charging mode is 1-hour charging mode (selected for different battery types); f) Realize intelligent IC management; g) Each charging pile (plug) is equipped with an operator for the user to select charging mode and guide operation, and display the battery status of electric vehicles and the user's IC card charge information to achieve unattended management;

Intelligent product: compared with traditional fuel vehicles, what is the core competitiveness of new energy vehicles? Intelligence seems to be the accepted answer. The reporter's visit found that more and more new energy vehicle enterprises have built a service system for the whole process of users' purchase and use of vehicles through the digital platform, and improved the digital life and after-sales service in the vehicle. From the perspective of configuration and performance, the new energy models of the three enterprises visited by the reporter have been able to achieve multiple functions such as car control, service and social networking with the help of the car machine system and APP, and the software upgrade and function iteration optimization can also be carried out after the car is sold, so as to realize the constant use and freshness of the car.
