Problems solved by technology

[0003] At present, most of the charger interfaces of mobile terminals are USB interfaces. When the power of the mobile terminal carried by the user is short, if the user does not carry a charger for the mobile terminal, he will look for a charger that can charge the mobile terminal. Yes, regardless of whether the specifications of the chargers are the same, and the situation that arises is that the same mobile terminal product may be used with chargers of different specifications, and the same charger may charge mobile terminals of different specifications, such as a 5.0 A V / 1.0A charger may charge a 5.0V / 0.55A, 5.0V / 0.7A or 5.0V / 1.2A mobile terminal, which will cause a mismatch between the charger and the mobile terminal, causing the mobile terminal to A series of safety issues such as overheating and burning out of the charging control part of the device, or causing the battery to work in an unsafe state
[0004] Therefore, there is a need for a charging method to solve a series of safety problems caused by the mismatch between the charger and the mobile terminal, and to ensure the safe use of the mobile terminal.

Abstract

The invention provides an intelligent charging method and system. According to the intelligent charging method, the specification of a charger is detected firstly; if an output current in the specification of the charger is larger than a standard current of a battery, unnecessary currents obtained after a user subtracts the standard current of the battery from the output current are dissipated, and output voltage of the charger and residual currents are input to a charging control unit to charge the battery; if the output current in the specification of the charger is smaller than the standard current of the battery, a current limit point of the charging control unit is regulated, and the output voltage and the output current of the battery are input to the charging control unit to charge the battery. Therefore, by the utilization of the intelligent charging method, a series of safety problems caused by mismatching of the charger and a mobile terminal can be solved, and the safe use of the mobile terminal is guaranteed.

Description

technical field [0001] The invention relates to the field of mobile terminal charging, in particular to an intelligent charging method and system. Background technique [0002] There are many types of chargers for existing mobile terminals. For example, the output voltage and output current of the charger are: 5.0V / 0.55A, 5.0V / 0.7A, 5.0V / 1A, 5.0V / 1.2A, etc. With the continuous increase of mobile terminal models, the specifications of the matching chargers also change in different ways. The output voltage of the chargers is generally 5V, but the magnitude of the current varies. [0003] At present, most of the charger interfaces of mobile terminals are USB interfaces. When the power of the mobile terminal carried by the user is short, if the user does not carry a charger for the mobile terminal, he will look for a charger that can charge the mobile terminal. Yes, regardless of whether the specifications of the chargers are the same, and the situation that arises is that the ...
