Method and system for wireless charging of car

Abstract

The invention belongs to the technical field of wireless charging, and discloses a method and system for wireless charging of a car. The system is provided with a charging unit, a charging transmitting unit, car wireless receiving units and a processing module, wherein the charging unit is used for providing energy; the charging transmitting unit is connected with the charging unit and used for transmitting the energy provided by the charging unit; the car wireless receiving units are connected with the charging transmitting unit wirelessly and used for receiving energy signals transmitted bythe charging transmitting unit; and the processing module is connected with the car wireless receiving units and used for processing the signals received by the car wireless receiving units to make the signals be converted into electric energy used by the car. When the car needs to be charged, electromagnetic signals wirelessly transmitted by the charging transmitting unit are received through themultiple wireless receiving units arranged in the car and transmitted into the car wireless receiving units and the processing module, and then the processing module converts the received electromagnetic signals into electric signals; and a battery in the car is charged by using the electric signals. The wireless charging method can be applied to the car wireless charging system.

Description

technical field [0001] The invention belongs to the technical field of wireless charging, in particular to a method and system for wireless charging of automobiles. Background technique [0002] In order to save energy and reduce the emission of automobile exhaust gas, people have developed automobiles that use electric energy to provide energy, that is, electric vehicles. Because the battery capacity of electric vehicles is limited, it needs to be charged frequently, but most of them use the connection charging method. Since the connection is exposed on the ground, there are not only dangers such as leakage, but also problems such as poor wire connection, easy damage, and regular replacement. There are many security risks. [0003] To sum up, the problems existing in the prior art are: electric vehicles adopt wired charging, which not only has dangers such as electric leakage, but also leads to problems such as poor connection, easy damage, and regular replacement, which b...
