Abstract

The invention relates to the technical field of intelligent household appliances, and discloses a wireless power supply method for a direct current power supply system. The method is applied to a mobile device, and the mobile device comprises a receiving coil. The method comprises the following steps: receiving a detection signal; when the detection signal is the first signal, adjusting the mobile device to move at a first speed towards the sending direction of the first signal; or, when the detection signal comprises the first signal and the second signal, adjusting the mobile device to move towards the sending direction of the first signal at the second speed, wherein the first speed is greater than the second speed. According to whether the received detection signal is the first signal or comprises the first signal and the second signal, the moving speed and the moving direction of the mobile device are adjusted, so that the mobile device can quickly and accurately approach the power supply equipment. The invention further discloses a wireless power supply device for the direct-current power supply system.

Description

technical field [0001] The present application relates to the technical field of wireless power supply, for example, to a method and device for wireless power supply in a DC power supply system. Background technique [0002] Wireless power supply does not require any physical connection, and power can be transmitted to the load in close proximity without contact. Wireless charging devices are more and more widely used in people's lives. Wireless charging devices can realize wireless power transmission in various ways, such as electromagnetic induction, electromagnetic resonance, and electromagnetic radiation. The wireless charging system includes a receiving coil and a transmitting coil, the transmitting coil is used for transmitting energy, and the receiving coil is used for receiving energy. The transmitting coil is set on the power supply device. In some current solutions, the receiving coil is set on the mobile device. The power supply device can obtain the location in...
