Embodiment Construction

[0022] The gist of the present invention is to overcome the deficiencies of the prior art. For example, during the charging process of the DC-DC charging IC, the charging stops due to factors such as temperature and overcharge protection, and the charger is still in place. At this time, there will be a probability that the IC will enter the timing The device is in an error state, causing the phone to fail to charge. Especially the built-in battery design, if the battery cannot be removed, the phone will not be able to resume charging normally. This is unacceptable to the user unless disassembled. The mobile terminal charging method and system provided by the present invention reset the timer inside the charging IC by acquiring the working status of the user control bit, which can effectively prevent the abnormal state of the DC-DC charger from not charging.

[0023] The following will describe in detail with reference to the accompanying drawings in conjunction with the embod...

Abstract

The invention discloses a method and system for charging a mobile terminal. The mobile terminal is connected with an external charger; a charging integrated circuit (IC) is arranged in the mobile terminal; and a control register is arranged in the charging IC. The method comprises the following steps that: (1) whether the control register of the charging IC is in a control position or not is judged, and if yes, the next step is performed, otherwise, the judgment is finished; (2) the working condition in the control position of the control register of the charging IC is obtained; (3) whether the working condition in the control position is in a state unable to charge, and if yes, the next step is performed, otherwise, the step (2) is returned; and (4) reset operation is performed on a timer in the charging IC and the step (1) is returned. Compared to the prior art, the method can reset the timer in the charging IC by acquiring the working condition in the control position of users and can effectively prevent abnormal conditions and no charging of direct current-direct current (DC-DC) chargers.

Description

technical field [0001] The present invention relates to a method and system for charging a mobile terminal, in particular to a method and system for preventing a DC-DC charger from being abnormally charged. Background technique [0002] With the development of mobile Internet, the development of mobile terminal products is also changing with each passing day. Smartphones are all developing towards larger screens, with higher and higher resolutions, and higher and higher camera pixels. Various peripheral applications are emerging in an endless stream. Then came the battery life problem, so the battery capacity is getting bigger and bigger. There are even more than 4000mAh battery configurations on the market. The larger the battery capacity, the more challenging it is to charge. The traditional charging method is far from meeting the demand, and users need a fast charging method. The DC-DC charger charging method is a fast charging method, which has high conversion efficie...
