TRANSMITTING APPARATUS FOR WIRELESS CHARGING, WIRELESS CHARGING SYSTEM, AND ELECTRIC AUTOMOBILE

摘要

Provided are a transmitting apparatus for wireless charging, a wireless charging system, and an electric automobile. The apparatus comprises: a transmitting coil (10) comprising N connection terminals, N being an integer greater than 1; a power module (20) having a first output end (To1) connected to a first connection terminal (E0) among the N connection terminals, and a second output end (To2) correspondingly connected, by means of N-1 controllable switches, to a second through an N^th connection terminal among the N connection terminals, respectively; a receiving module for receiving charging request information from a device to be charged; and a control module (40) respectively connected to the receiving module and control ends of the N-1 controllable switches, and used to control the N-1 controllable switches according to the charging request information, so that the power module (20) can provide electric energy to the device to be charged by means of the transmitting coil (10). The apparatus can improve wireless charging efficiency and security, and can be used in a wide range of applications.
