Matrix network wireless power supply system and charging method for mobile devices

Abstract

The invention discloses a matrix network type wireless power supply system applied to mobile equipment and a charging method thereof. The wireless power supply system consists of a transmission end power supply device, a reception end power reception device and a detection control device, wherein the transmission end power supply device is mounted below the ground of a charging area; the receptionend power reception device is mounted on the mobile equipment; and the output end of the detection control device is connected with the transmission end power supply device. According to the matrix network type wireless power supply system applied to the mobile equipment and the charging method thereof, the mobile equipment can realize stable power output at any position in the charging area, sothat flexible and efficient charging in a large scale is realized. Through the charging method, the cooperative work manner of a transmission coil matrix is controlled, so that the high efficiency andlow radiation of wireless transmission of electric energy are ensured; and meanwhile, the decoupling of the coils does not need to be considered, so that the deficiencies of the present wireless power supply systems are well solved.

Description

technical field [0001] The invention belongs to the technical field of wireless power transmission, and in particular relates to a matrix network wireless power supply system applied to mobile devices and a charging method thereof. Background technique [0002] With the outbreak of environmental pollution and the oil crisis, with the advantages of zero emissions, high energy utilization rate, and a wide range of energy sources, it has become an inevitable trend in the future to replace traditional fuel oil as the power source of mobile devices. However, there are many problems in the traditional contact charging method: (1) charging is inconvenient, limited by the interface, and the charging process is cumbersome; (2) the maintenance cost is high, and the charging plug has friction loss, requiring frequent maintenance; (3) poor safety, Both the power supply interface and the charging plug have high voltage, which will pose a safety threat to the operator. The use of wireles...
