Wireless charging method with anti-shake processing, watch and memory medium

Abstract

The invention discloses a wireless charging method with anti-shake processing, a watch and a memory medium. The charging method comprises the steps of S1, detecting a load disconnection state between a wireless charger and a to-be-charged device; and S2, when it is detected that the load disconnection state is a pseudo load disconnection state, not generating a charging stopping instruction, thereby carrying out charging continuously. According to the method, the watch and the memory medium, an intermittently alternate charging phenomenon possibly appearing in a charging process can be eliminated.

Description

Technical field [0001] The invention relates to the field of wireless charging. More specifically, it relates to a wireless charging method with anti-shake processing, a watch, and a storage medium. Background technique [0002] Many handheld electronic devices today use wireless chargers and wireless charging methods. In particular, most smart watches currently on the market have adopted wireless chargers and wireless charging methods. [0003] Wireless charging can avoid the use of wires, which brings convenience to users. However, there are still some problems that need to be solved or optimized in actual use. For example, some smart watches will have the phenomenon that the screen turns on and off continuously after the charge reaches more than 90%, and this phenomenon will not disappear until it is fully charged. [0004] The root cause of this phenomenon is that when the charging capacity reaches more than 90%, the load power of the wireless charger becomes smaller, which c...

Problems solved by technology

However, since the smart watch at this time is still placed in the charging area near the base of the wireless charger, the wireless charger will detect the presence of the smart watch again and start charging it again.

The above process is carried out alternately, which leads to the intermittent charging process, which leads to the continuous alternation of the screen of the smart watch that the user sees.

Brings a bad experience to users who use wireless charging

[0005] At the same time, according to the feedback from the hardware manufacturer of the wireless charger, due to the limitations of the current technology, it is impossible to completely distinguish the normal communication waveform and load modulation in the above situation from the hardware, and it is impossible to distinguish between the pseudo load disconnection The load disconnection event is triggered under the real load disconnection state, so it is impossible to eliminate the above phenomenon that the screen is constantly on and off

Because when the charging power reaches more than 90%, the charging current becomes smaller, and there is a process similar to FM modulation, so useful signals and noises become difficult to be accurately detected and distinguished by the wireless charging chip
