In step 701, the atmospheric pressure value of baroceptor is obtained.
In a step 702, judge whether atmospheric pressure value exceedes safe atmospheric pressure value.If the air pressure sensing that control chip gets
The safe atmospheric pressure value that the atmospheric pressure value of device exceedes, then into step 703；Otherwise return to step 701, continues to obtain baroceptor
Atmospheric pressure value, untill into step 703.
In step 703, stop being charged to battery core.
Because step 701 to step 703 is roughly the same to step 603 with the step 601 in the 5th implementation method, it is intended to by
Control chip obtains the atmospheric pressure value of baroceptor, and when the atmospheric pressure value for obtaining exceedes safe atmospheric pressure value, stops being filled to battery core
Electricity, here is omitted.
In step 704, abnormal information is sent to the processor of terminal, terminates this battery protection flow.
Specifically, control chip when atmospheric pressure value exceedes safe atmospheric pressure value stops that battery core is charged and/or stopped to battery core
Outwards after electric discharge, the processor of abnormal information to terminal can be also sent, the change of present battery air pressure inside is led by processor
The abnormal information of cause is analyzed, and carries out subsequent operation.
It should be noted that in present embodiment, the abnormal information that control chip sends can include inside present battery
The atmospheric pressure value positional information corresponding with the atmospheric pressure value and the atmospheric pressure value time, the duration that change etc., in reality
Can be set according to usage scenario, the requirement to air pressure detection accuracy in the application of border, be not limited here.
Compared with prior art, control chip stop to battery core charge or stop battery core outwards electric discharge after, by hair
Raw abnormal information is done further operation and is processed to the processor of terminal by the processor of terminal, accomplishes to be controlled from source
System, further ensures the service life of battery core, and user's safety in use.
7th implementation method of the invention is related to a kind of battery protecting method, and idiographic flow is as shown in Figure 8.
In step 801, the abnormal information from battery is received.
Specifically, processor receives the abnormal information from battery, and the abnormal information can include inside present battery
The atmospheric pressure value positional information corresponding with the atmospheric pressure value and the atmospheric pressure value time, the duration that change etc., in reality
Can be set according to usage scenario, the requirement to air pressure detection accuracy in the application of border, and be built with the control chip of battery
Corresponding agreement is found, confirmation needs which abnormal information sent and received, is not limited here.
In step 802, abnormal information is analyzed, and controls charging circuit to stop the voltage being exported to battery, terminate this
Battery protection flow.
Specifically, processor can charge electric after being analyzed to the abnormal information for receiving according to analysis result control
Road stops the voltage being exported to battery.In actual applications, processor according to analysis result control charging circuit output when,
