Step 404, it if level signal remains unchanged in preset time, controls tip parts and cancels display charged state Prompt message.

Wherein, the level signal of the charge management circuit output end of electronic equipment remains high level or low level not Becoming, then illustrates that charge management circuit is not received by energy pulse at this time, electronic equipment has been detached from wireless charging base, at this point, If the tip parts of electronic equipment is in charge prompting state, cancel the charge prompting state of tip parts, if electronics The tip parts of equipment does not carry out charged state prompt, then continues to keep this state.

Wherein, it after electronic equipment is fully charged, sends energy to wireless charging base and exports shutdown signal, cradle receives After signal, stop energy output, only interval sends a ping phase in about 1.35 seconds.

Specifically, preset time is more than or equal to 1.35 seconds.

Wherein, the frequency that wireless charging device sends ping phase is about 1.35 seconds/time, therefore, preset time is arranged To be more than or equal to 1.35 seconds, as long as ensureing that electronic equipment on wireless charging base, can identify in preset time.

Specifically, tip parts is indicator light.

Wherein, the tip parts of electronic equipment is indicator light, is shone, so that user intuitively knows charge prompting shape State.
