Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicles, and in particular to a smart charging pile for a smart electric vehicle. Background Art

[0002] With the rapid development of electric vehicle technology, driverless electric vehicles are gradually leading the transformation of travel modes with their excellent automation and intelligent features. However, despite the significant progress in electric vehicle technology, its charging infrastructure, especially the smart charging solutions for driverless vehicles, still faces many challenges.

[0003] The electric vehicle charging piles currently on the market, whether AC or DC, have met the basic charging needs of electric vehicles to a certain extent, but they still have obvious shortcomings when dealing with the charging needs of driverless electric vehicles. First of all, the lack of intelligence is one of the main problems facing current charging piles. Existing charging piles generally lack the ability to communicate intelligently with driverless electric vehicles, and cannot achieve automatic docking and disconnection of charging interfaces, as well as intelligent adjustment of charging parameters. This makes the charging process cumbersome, and charging efficiency and safety are difficult to guarantee.

[0004] Secondly, compatibility and versatility are also key factors that restrict the development of charging piles. The charging interface standards of electric vehicles of different brands and models are not unified, which limits the versatility of charging piles. Users need to carry multiple charging interface adapters, which not only increases the burden on users, but also reduces the efficiency of charging piles. In addition, the charging protocol and communication protocol of charging piles also lack unified standards, further exacerbating the compatibility problem.

[0005] Finally, user experience and convenience are also issues that need to be addressed in the current charging piles. The layout and number of charging piles often cannot meet the actual needs of users, especially in remote areas or during peak hours, where users often have to queue up to charge. This not only reduces user satisfaction, but also limits the popularity and development of electric vehicles. In addition, the cumbersome operation during the charging process and the lack of a convenient user interface and interactive experience also affect the user experience.

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention proposes an intelligent charging pile system for an intelligent electric vehicle. Summary of the invention
