Abstract

The invention discloses a low-power wireless charging device and method. The low-power wireless charging device comprises a charging panel arranged in the middle of a top cover on a body. Antiskid nails are arranged on the outer side of the charging panel. Pressure sensors arranged on the peripheries of the antiskid nails. A base is also arranged on the body. A storage battery arranged on the base, and heat dissipation boxes are arranged on the periphery of the storage battery. A plurality of heat dissipation holes are formed in the inner sides and the outer sides of the heat dissipation boxes. Fans are fixed in the heat dissipation boxes, and the upper portions of the heat dissipation boxes are connected with the top cover. An LED lamp box is wound around the edge of the periphery of thebase. A coil fixing plate is arranged at the top end of the storage battery. Power transmission coil fixing grooves are evenly distributed, and power transmission coils are evenly arranged in the power transmission coil fixing grooves. The coil fixing plate is fixed on the storage battery, and the power transmission coils are fixed in the power transmission coil fixing grooves. The storage batteryis connected with the pressure sensors, the pressure sensors and the storage battery are both connected with an external power source, and a single-chip microcomputer is connected with the pressure sensors, the heat dissipation boxes, the power transmission coils and the LED lamp box. According to the invention, the uniformity of energy transmission is improved, and the charging efficiency is improved.

Description

technical field [0001] The invention relates to the field of wireless charging, in particular to a low-power wireless charging device and method. Background technique [0002] Wireless charging technology originates from wireless power transmission technology, which can be divided into low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method for charging mobile phones, but ZTE's electric vehicle wireless charging method uses inductive charging. High-power wireless charging often adopts a resonant type (most electric vehicle charging uses this method), and the power supply equipment (charger) transmits energy to the power-consuming device. The device uses the received energy to charge the battery and at the same time supply itself. for operational purposes. Since energy is transmitted between the charger and the power-consuming device by a magnetic field, the two are not connected b...
