Power protection system and method of mobile device

Abstract

The invention provides a power protection system and method of a mobile device. The system comprises a charging unit which comprises input ends connected with a battery and a power adapter, an output end and an enablement end, and is used for outputting a gating signal when determining that the battery is charged by the power adapter; a processing unit which is used for stopping outputting a charging permission signal when detecting a hardware starting instruction, and starting the corresponding hardware in a delayed manner, and when detecting a hardware stop instruction, stopping the corresponding hardware and outputting the charging permission signal in a delayed manner; and a protection unit which comprises two input ends connected with the output end of the charging unit and the output end of the processing unit respectively, and an output end connected with the enablement end of the charging unit, and is used for determining whether an enable signal for allowing battery charging is output to the enablement end by analyzing the signals of the two output ends, and if the enable signal is output, charging the battery. The power protection system and method can prevent current impact on a charging circuit of the hardware starting and stopping in the process where the power adapter charges the battery.

Description

technical field [0001] The invention relates to a power protection technology, in particular to a power protection system and method for mobile equipment. Background technique [0002] With the intelligentization of mobile phones, mobile phones bring people a convenient lifestyle, and many functions are integrated into mobile phones. Such as online shopping, games, and Internet of Things control functions through mobile phones and other controlled electronic devices. A mobile phone is no longer just for calling and sending text messages as it used to be. This will inevitably require the phone to have a long battery life. People often use mobile devices such as mobile phones while charging. [0003] Using a mobile device while charging will increase the power consumption of its charging circuit, and the direct negative result is that the phone becomes hot. The internal integrated chip is often in the limit working state. The long-term heat loss coupled with the impact of ...
