Anke Innovation has applied for a patent for wireless charging detection method, allowing both chargers to enter charging mode when there is interference when they are close together

Article Source:China National Intellectual Property Administration | Author:Financial Sector | Issuing Time:2024.04.07
On April 5, 2024, the financial sector reported that according to the announcement of the China National Intellectual Property Administration, Anke Innovation Technology Co., Ltd. applied for a project named "Wireless charging detection method, detection circuit and computer storage medium", with the public number of CN117825787A and the application date of September 2022.

The patent abstract shows that the present application relates to the field of wireless charging technology and discloses a wireless charging detection method, detection circuit, and computer storage medium. The wireless charging detection method includes: collecting the current of the first charger through a current acquisition module to obtain a voltage waveform; After detecting that the device to be charged is placed on the first charger and determining that the second charger is in a charging state, obtain the voltage waveform within the first preset time as the first voltage waveform; Compare the first voltage waveform with the first preset voltage waveform; If the first voltage waveform matches the first preset voltage waveform, it is confirmed that the first charger is not charging the device to be charged. Control the second charger to stop charging, and after detecting that the first charger is charging the device to be charged, control the second charger to restart charging. The state of the first charger obtained through waveform matching in this application controls the second charger, so that both chargers can enter the charging state when there is interference when they are close together.
