[0044] see figure 1 , propose the first embodiment of the charging method of the present invention, the charging method includes the following steps:

[0045] Step S101, the mobile terminal detects the charging current and battery voltage.

[0046] After the mobile terminal is electrically connected to the charger, the charger charges the mobile terminal. During the charging process, the mobile terminal detects the charging current and battery voltage in real time.

[0047] Step S102, the mobile terminal judges whether the preset threshold corresponding to the battery voltage is greater than the charging current.

[0048] As the charger charges the battery of the mobile terminal, the voltage of the battery gradually increases, and as the voltage of the battery increases, the optimal charging current also changes. That is, the battery voltage value in each range segment has different corresponding optimal charging current values. In order to improve charging efficiency, it is...

Abstract

The invention discloses a charging method and a charging system. The charging method comprises the steps that a mobile terminal detects charging current and battery voltage, and sends a corresponding control signal to a charger according to the detected charge current and battery voltage, and the charger controls output voltage according to the corresponding control signal, so that the charge current can be adjusted. The optimal charge current can be matched according to the current battery voltage, so that the charging efficiency is maximized, and the quick and efficient charging is achieved. The charger directly controls the output voltage to adjust the magnitude of the charging current, so that charging heat due to the loss of electric energy is not caused, the charging safety is improved, and the energy waste is reduced.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a charging method and a charging system. Background technique [0002] The functions of mobile terminals are becoming more and more powerful, and their display screens are also getting bigger and bigger, which greatly improves the user experience. In addition to using mobile terminals for basic calls, users are more likely to use mobile terminals for work, entertainment, and surfing the Internet. Surfing, therefore, is used more and more frequently, causing the mobile terminal to consume a lot of power, so its battery capacity is getting bigger and bigger, and it needs to be charged more and more frequently. How to charge the mobile terminal quickly and efficiently is an urgent problem to be solved at present. [0003] In the process of charging the battery of the mobile terminal, the optimal charging current is different in each charging stage, and the optimal charging curr...
