Method for wirelessly transmitting electric energy to charge a plurality of or many kinds of loads

Abstract

The invention relates to a method for wirelessly transmitting electric energy to charge a plurality of or many kinds of loads. The method comprises the following steps of: 1, performing frequency conversion to convert alternating current commercial power into high-frequency alternating current voltage; 2, enabling the high-frequency alternating current voltage to generate an outwards-emitted alternating electromagnetic field by using a high-frequency coil arranged in a special power tray; 3, manufacturing a standard electricity gaining device for different kinds of loads, wherein the standard electricity gaining device comprises a resonance circuit, a high-frequency rectification circuit and a direct current filtering circuit, which are connected in sequence; and 4, placing one or more loads of the same kind or different kinds on the special power tray without wire connection, and transmitting the electric energy transmitted by the high-frequency coil in the special power tray into the loads for charging. The method is implemented by methods such as power conversion, wireless transmission of the electric energy and adoption of the standard electricity gaining device for the different loads, and is convenient, economical, quick and wide in application range.

Description

technical field [0001] The present invention relates to a charging method, in particular to a method of transmitting electric energy in a wireless manner and simultaneously charging multiple or multiple loads from one power supply. Background technique [0002] At present, chargers have a wide range of applications and uses in various fields, especially in the fields of production and life, they are widely used in common electrical equipment such as mobile phones and cameras. The existing chargers basically charge electrical equipment through the following two charging methods. [0003] The first is a contact method that directly connects the power supply to the electrical equipment that receives power through metal wires to charge the built-in battery of the electrical equipment. However, since this charging method adopts metal wires to be directly connected, generally speaking, a charger can only charge one electrical device, but cannot charge multiple or multiple electri...

Problems solved by technology

However, since this charging method is directly connected with metal wires, in general, a charger can only charge one electrical device, but cannot charge multiple or multiple electrical devices at the same time.

[0004] The second is a wireless charging method, but although the existing wireless charging method does not use wires to connect the power supply and the electrical equipment receiving power, this charging method can only realize one charger to charge one electrical equipment. It cannot charge multiple devices at the same time, let alone charge multiple devices at the same time
