Mobile terminal with fake battery function and method for enabling and disabling fake battery

Abstract

The invention discloses a mobile terminal with a false battery function and a false battery enabling and disabling method of the mobile terminal. The mobile terminal comprises a battery, a charging interface, a power management chip, a voltage conversion module and a switch module. The charging interface is connected with the power management chip through the voltage conversion module. The switch module is connected with the voltage conversion module, the power management chip and the battery. According to the mobile terminal with the false battery function and the false battery enabling and disabling method of the mobile terminal, when the false battery function is needed, the power management chip sets a voltage value, and the voltage conversion module converts the voltage output by the charging interface into the voltage value set by the power management chip to supply power to the mobile terminal. Since the voltage provided by a charger is used for simulating the output voltage of a false battery, the false battery does not need to be manufactured additionally, research and development cost is lowered, and the research and development cycle is shortened; moreover, a direct-current power source is not needed, and the mobile terminal is more convenient to use.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a mobile terminal with a fake battery function and a method for enabling and disabling the fake battery. Background technique [0002] A fake battery is an electronic device with the same interface as a real battery, but without the ability to store and release electrical energy. For the mobile terminal, since the interface of the fake battery is the same as that of the real battery, the mobile terminal does not know which battery is connected. [0003] Such as figure 1 As shown, the real battery has an ID pin, a temperature feedback pin, a positive pole and a negative pole. When the real battery is connected to the mobile terminal, the ID pin, the temperature feedback pin, the positive pole and the negative pole of the real battery are respectively connected to the corresponding interface of the mobile terminal. The voltage difference between the positive pole and the ne...

Problems solved by technology

[0006] However, because fake batteries often require a DC power supply for power supply, and the DC power supply is bulky, heavy, and inconvenient to move; moreover, fake batteries are different from real batteries and need to be remade, which makes the research and development cycle of mobile terminals long and the research and development costs are high.
