The power management chip of a mobile terminal such as a smart phone can integrate the battery presence detection function. After the mobile terminal is connected to the charging device and detects that the battery is in place, the power management chip controls the charging device to charge the mobile terminal to the first current value. , when it is detected that the battery is not in place, the power management chip controls the charging current of the charging device for the mobile terminal to be a second current value, where the first current value is greater than the second current value.

Wherein, the mobile terminal includes a terminal body and a battery, the presence of the battery means that the battery is connected to the body of the terminal, and the absence of the battery means that the battery is not connected to the body of the terminal.

Through the above method, it can be ensured that the charging device charges the mobile terminal with a small current when the battery is not in place, and charges the mobile terminal with a relatively large current when the battery is in place, thereby ensuring the safety of the user when using the mobile terminal. sex.

In the development and testing stage of the mobile terminal, for example, when testing the mainboard of the mobile terminal, the battery of the mobile terminal cannot be connected to the main body of the terminal, that is to say, the battery is usually not in place, but the power management chip on the mainboard will still Detect whether the battery is in place, then the power management chip will detect that the battery is not in place at this stage of development and testing. When the motherboard is connected to the host computer for firmware download, the charging current that the host computer supplies to the motherboard will be set to the second current value. , and the relatively small second current value is not enough for the motherboard to complete the firmware download from the host computer, which usually leads to a download failure, which brings great inconvenience to the development and testing work.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a first embodiment of a current setting method for a mobile terminal according to the present invention. In this embodiment, the current setting method of the mobile terminal may include the following steps:

Step 11: Connect to the host computer.

In step 11, the host computer may be a PC (personal computer, personal computer) end. The main board of the mobile terminal establishes a power supply connection and a communication connection with the upper computer. Specifically, the connection may be performed through a USB (Universal Serial Bus, Universal Serial Bus) interface. After connecting to the host computer, hardware power-on and software initialization can be performed for the power management chip.

When connecting, on the one hand, the PC side can supply power to the main board of the mobile terminal through the VBUS pin of the USB interface; Pin D - to communicate with the motherboard.

Step 12: Determine whether the mobile terminal has successfully downloaded the firmware.

In step 12, as described above, the mobile terminal establishes a connection with the host computer and triggers the execution of the step of judging whether the mobile terminal has successfully downloaded the firmware.

Determining whether the mobile terminal has successfully downloaded the firmware may be: reading the state value of the flag bit in the register of the mobile terminal; if the state value is the first state value, the mobile terminal has successfully downloaded the firmware; if the state value is the second state value , the mobile terminal fails to download the firmware.

Determining whether the mobile terminal has successfully downloaded the firmware may also be: judging whether the used storage capacity of the memory of the mobile terminal is equal to the preset storage capacity; if the used storage capacity of the memory of the mobile terminal is equal to the preset storage capacity, then the mobile terminal The firmware has been successfully downloaded; if the used storage amount of the memory of the mobile terminal is less than the preset storage amount, the mobile terminal has not successfully downloaded the firmware.

Judging whether the mobile terminal has successfully downloaded the firmware can also be: judging whether the hash value of the data stored in the memory of the mobile terminal is equal to the preset hash value; if the hash value of the data stored in the memory of the mobile terminal is equal to the preset hash value; If the set hash values are equal, the mobile terminal has successfully downloaded the firmware; if the hash value of the data stored in the memory of the mobile terminal is not equal to the preset hash value, the mobile terminal has not successfully downloaded the firmware.

For details, please refer to the description below.

It should be understood that the above-mentioned judgment methods can be combined with each other to judge whether the mobile terminal has successfully downloaded the firmware. When the values are equal, a judgment result that the mobile terminal has successfully downloaded the firmware is generated.

In step 12, if the mobile terminal fails to download the firmware, step 13 is executed: the charging current provided by the host computer to the mobile terminal is set to the first current value.

In step 13, optionally, setting the charging current provided by the host computer to the mobile terminal to the first current value may specifically be: judging whether the battery of the mobile terminal is in place, and when judging whether the battery is in place or not, both The charging current is set to the first current value.
