Embodiment Construction

[0047] The invention provides a mobile terminal and a charging control method thereof, which can stop charging when detecting that the battery is frequently switched between charging and discharging, and can greatly reduce the switching between charging and discharging of the battery, thereby prolonging the service life of the battery. In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0048] see figure 2 , the charging control method of the mobile terminal provided by the present invention includes:

[0049] S100. Acquire the maximum charging current of the charging device when it is detected that the mobile terminal is connected to the char...

Abstract

The invention discloses a mobile terminal and a charge control method thereof. The charge control method comprises the following steps: A, when it is detected that the mobile terminal is connected with a charging device, obtaining the maximum charge currents of the charging device; B, starting charging, and determining whether the charge and discharge switching frequency of a battery within a first fixed timed period is greater than first preset frequency: in case of yes, executing step C, and otherwise repeating step B; C, stopping charging, and determining whether the frequency that the discharge current of the battery is greater than the maximum charge currents is greater than second preset frequency: in case of yes, repeating step C, and other wise, executing step D; and D, determining whether the battery is fully charged: in case of yes, ending charging, and otherwise, returning to the step B, such that frequent charge and discharge switching can be reduced, the battery is well protected, and the service life of the battery is also prolonged.

Description

technical field [0001] The present invention relates to the technical field of mobile charging, in particular to a mobile terminal and a charging control method thereof. Background technique [0002] At present, all mobile terminals are powered by rechargeable batteries, and the mobile terminals also support the function of charging anytime and anywhere. Such as figure 1 As shown, when the mobile terminal is connected to the charging device (common charging devices such as power banks, chargers, computers, etc.), the charging current Ichg input by the charging device to the mobile terminal is divided into two channels: one is the terminal current Isys, which is used for charging for the mobile terminal. The terminal supplies power so that the mobile terminal can be used normally; the other is the battery charging current Ibat, which is used to charge the battery; and the former takes precedence over the latter. [0003] After the mobile terminal is connected to the chargin...
