Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to an induction positioning type charging pile circuit. Background Art

[0002] With the transformation of the global energy structure and the improvement of environmental awareness, new energy vehicles have been widely promoted and applied. As an important supporting facility for new energy vehicles, the distribution and use of new energy vehicle charging piles directly affect the user experience and charging efficiency of new energy vehicles. However, in the existing technology, the positioning relationship between new energy vehicle charging piles and vehicles has not been fully optimized, and there are many problems and limitations.

[0003] First, most existing charging piles do not have the function of real-time interaction with cars, which makes it difficult for users to accurately obtain the real-time location and usage status of charging piles when looking for charging piles and charging. This situation often causes users to spend a lot of time and energy looking for available charging piles, and they may even find that the charging piles are occupied or unavailable after arriving at the location of the charging piles, which seriously affects the user experience.

[0004] Secondly, due to the lack of effective positioning and interaction mechanism between the charging pile and the car, users cannot accurately judge the relative position between the charging pile and the car during charging, which may cause excessive stretching, twisting or damage of the charging cable, thereby causing safety hazards. At the same time, due to the lack of accurate positioning, users may not position their vehicles correctly when parking for charging, resulting in low charging efficiency or charging failure.

[0005] There is currently no circuit that can enable interactive communication and positioning between charging piles and vehicles, making the interaction between charging piles and vehicles more convenient and efficient. Summary of the invention
