Embodiment Construction

[0022] The main purpose of the present invention is to overcome the shortcomings of the prior art. For example, during the charging process of the DC-DC charging IC due to temperature, overcharge protection and other factors, the charging stops while the charger is still in place. At this time, the IC enters the timer. In the wrong state of the device, the phone cannot be charged. Especially with the built-in battery design, the battery cannot be removed and the phone will not be able to resume charging normally. Unless dismantled, this is unacceptable to users. The mobile terminal charging method and system provided by the present invention resets the timer inside the charging IC by acquiring the working state of the user control bit, which can effectively prevent the abnormal state of the DC-DC charger from not charging.

[0023] The following detailed description will be given in conjunction with the embodiments with reference to the accompanying drawings in order to give a m...

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, and in particular to a method and system for preventing abnormal non-charging of a DC-DC charger. Background technique [0002] With the development of the mobile Internet, the development of mobile terminal products is also changing with each passing day. Smart phones are all developing towards larger screens, with higher resolution and higher camera pixels. Various peripheral applications are also emerging in endlessly. What follows is the battery life problem, so the battery capacity is getting larger and larger, and there are even more than 4000mAh battery configurations on the market. The larger the battery capacity, the charging becomes a test. The traditional charging method is far from being able to meet the demand, and users need fast charging methods. The DC-DC charger charging method is a fast charging method. It has high conversion efficiency and can provide ...
