Step 402, the charging beginning.
Step 404, what judge whether to adopt is the mode of wired charging.If judged result is yes, enter step 406, if the determination result is NO, enter step 410.
Step 406 starts wired charging, closes wireless charging.When detecting wired charging modes and wireless charging mode and coexist, close the wireless charging mode, only use wired charging modes, thereby the problem of the damage terminal hardware that may cause when having avoided wireless charging and wired charging jointly to use, guaranteed the safety of terminal, made the use that the user can be relieved.
Step 408 continues to adopt wired mode to charge, until battery is filled.
Step 410 starts the wireless charging mode, and the cancellation maximum charging current is the restriction of 500mA, controls charging current by software according to the specification of battery and charger.
Step 412 in the wireless charging process, detects regularly whether wired charging modes accesses, if testing result is yes, then returns step 404, if testing result is no, then enters step 414.
Step 414 if do not detected wired charging modes access, then continues to adopt the wireless charging mode to continue battery is charged, thereby guarantees that charge function can normally use.
Whether step 416 detects battery and is filled, if testing result be yes, complete charge then is if testing result is otherwise returns step 412.
Fig. 5 shows the particular flow sheet when terminal charge interrupts according to an embodiment of the invention.
Step 502 after wired charging modes and wireless charging mode coexist, is closed wireless charging, uses in the situation of wired charging, in the process of charging, detecting charging and interrupting.
Step 504 judges whether battery is filled.If judged result is yes, enter step 510, if the determination result is NO, enter step 506.
Step 506 judges whether the charger of wired charging is extracted.If judged result is yes, enter step 508, if the determination result is NO, enter step 512.
Step 508 starts the wireless charging mode, and the cancellation maximum charging current is the restriction of 500mA, controls charging current by software according to the specification of battery and charger.
Step 512 withdraws from charging and interrupts, and continues as terminal charge.
More than be described with reference to the accompanying drawings technical scheme of the present invention, by technical scheme of the present invention, solved wireless charging and wired charging when accessing simultaneously, the terminal charge that causes is chaotic, damages the problem of hardware circuit, the user can be switched between wired charging and wireless charging freely, solved simultaneously when wireless charging, terminal itself has increased charging current to the restricted problem of wireless charging electric current, reduce the time of wireless charging, thereby promoted user's experience.
