As one of the most promising green vehicles in the market today, electric vehicles will be extremely popular in the future, and the future market prospects will be extremely large. Under the background of the global energy crisis and the serious environmental crisis, the Chinese government actively promotes the application and development of new energy vehicles. As an indispensable supporting infrastructure for the development of electric vehicles, the charging/replacement station is undoubtedly important. The charging pile ranking also shows this feature and reflects China's requirements for products:

(1) In terms of safety, the new standard embodied in the charging pile ranking has increased the functions of charging interface temperature monitoring electronic lock, insulation monitoring and bleeder circuit uniquely. The device follows the refinement of the safety protection of the DC charging vehicle end interface. Relevant measures, clearly prohibiting the application of unsafe charging mode, can effectively avoid accidents such as electric shock and equipment burning, and ensure the safety of electric vehicles and users during charging, and the quality products of China's reliable charging piles are ranked. This quality is reflected in the quality.

(2) In terms of compatibility, the domestic well-known charging pile ranks that the AC-DC charging interface type and structure are compatible with the original standard. The new standard modifies the contact and mechanical lock size requirements of some charging pile equipment, but the old and new plug sockets remain Can cooperate with each other, the electronic charging interface of the DC charging interface is added, and this situation does not affect the electrical connection between the old and new products. Therefore, the charging pile ranking side reflects that the user only needs to update the communication protocol version, that is, the new power supply device can be determined. And electric cars can guarantee basic charging functions.

The above is the product technical requirements reflected in the charging pile ranking, and the new standard of charging facilities puts higher requirements on safety and compatibility. This is also a higher requirement for charging equipment manufacturers, and the industry concentration will be improved. Enterprises with strong technical strength can usher in a broader space for development. Therefore, relevant people can understand the technical requirements of the products through the charging pile ranking, and select the products that meet these requirements to be put into use, so that each consumer can use the charging piles safer and more assured.
