According to the information, on May 24, Huawei Technologies Co., Ltd.’s patent for “receiving end, transmitting end, system, control method and electric vehicle of wireless charging” was authorized.
The abstract shows that the present application discloses a wireless charging receiver, transmitter, system, control method and electric vehicle, and relates to the technical field of wireless charging. Among them, the low-frequency magnetic field receiving coil at the receiving end converts the low-frequency magnetic field into an induction signal; when the low-frequency magnetic field transmitting coils at the receiving end stop working, the controller at the receiving end assigns each low-frequency magnetic field transmitting coil a signal characteristic different from that of the current induction signal. , and the corresponding relationship between each low-frequency magnetic field transmitting coil and the assigned signal characteristics is sent to the transmitting end of the wireless charging; it is also used to determine the power transmitting coil and power using the induction signal with the assigned signal characteristics when the low-frequency magnetic field transmitting coil is working The relative position of the receiving coil. The transmitter controller controls the inverter circuit according to the corresponding relationship to make each low-frequency magnetic field transmitter coil work. Mutual interference between low-frequency magnetic field signals of adjacent parking spaces can be avoided by using the above receiving end and transmitting end.
