Abstract

The invention discloses a wireless charging pile of an electric automobile based on electromagnetic force and a charger, and relates to a wireless charging technique of the electric automobile, which aims at solving the problems of inconvenience and unsafety when the electric automobile is charged by the existing charging device of the electric automobile via the connecting cable. The wireless charging pile comprises a charging pile controller and a plurality of charging interfaces, wherein each charging interface comprises an electromagnet and a telescopic mechanism; each electromagnet is fixedly arranged on the corresponding telescopic mechanism; the charging pile controller is used for controlling the engaging and disengaging of an electromagnet power source; the charger comprises a charger body and an induction coil; the charger body is used for converting the current produced by the induction coil into electric energy required by the electric automobile. The wireless charging pile and the charger have the advantages that by utilizing the electromagnetic principle, the electric energy is converted into a magnetic field in the charging pile, the magnetic field changes, and the current is produced in the induction coil, so as to reach the purpose of charging for the electric automobile; the charging by connecting with the cable is not needed, so that the convenience and safety are realized; a plurality of electric automobiles can be simultaneously charged by one charging pile, so that the utilization rate of the charging pile is realized.

Description

technical field [0001] The invention relates to wireless charging technology for electric vehicles. Background technique [0002] Conventional charging devices for electric vehicles charge electric vehicles through connecting cables, which poses a great potential safety hazard for charging in bad weather (rain, snow, etc.) environments. However, most of today's wireless charging technologies use the principle of electromagnetic induction, and energy transmission is achieved through energy coupling through coils. The charging power is small, and it is not suitable for large-scale electrical equipment such as electric vehicles. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the conventional electric vehicle charging device charges the electric vehicle through a connection cable, which is inconvenient and unsafe, and provides an electric vehicle wireless charging pile and charger based on electromagnetic force. [0004] T...
