Battery activation method and device of mobile terminal

Abstract

The invention discloses a battery activation method and device of a mobile terminal. The method comprises the following steps: judging whether battery voltage of the mobile terminal is smaller than threshold voltage after the mobile terminal is connected with a charger; loading first voltage and first current to two ends of the battery to activate the battery when the battery voltage is smaller than the threshold voltage; detecting the battery voltage of the battery again, judging whether the battery voltage is smaller than the threshold voltage; if so, loading the first current to two ends of the battery again and sequentially adding first voltage with the preset voltage value, and detecting the battery voltage of the battery again until the battery voltage is not smaller than the threshold voltage, if not, restarting the mobile terminal; directly activating the battery by connecting the charger after over-current protection of the battery without dismantling the battery, so that great convenience is brought about for a user.

Description

technical field [0001] The present invention relates to the field of mobile terminals, and in particular, to a method and device for activating a battery of a mobile terminal. Background technique [0002] At present, in order to meet the requirement that the thickness of the mobile terminal is getting thinner and thinner, the accessory battery of the mobile terminal also tends to be non-removable. In the daily use of mobile terminals, it is inevitable that the mobile terminal will be short-circuited (overcurrent) due to static electricity, falling, and extrusion. In traditional mobile terminals with detachable batteries, the battery can be restored to a normal state (that is, activated) by simply re-plugging and unplugging the battery; after the battery is protected, it will detect the load connected to the battery, and when the load impedance is sufficient When high, it will automatically return to normal state. However, in a mobile terminal with a non-removable battery,...
