The motherboard processor obtains relevant information inside the battery based on I2C communication.

In other words, it can be determined whether the relevant information inside the battery (such as the real voltage inside the battery) can be obtained through I2C communication to detect whether the second battery connector is successfully engaged. For example, if the relevant information inside the battery can be obtained through I2C communication, it can be considered that the communication connection between the battery and the motherboard processor is normal, and the male socket of the second battery connector on the battery and the female socket of the second battery connector can be determined. The seat buckle is closed successfully. Optionally, if the relevant information inside the battery cannot be obtained through I2C communication, it can be considered that the communication connection between the battery and the motherboard processor is abnormal, and it can be determined that the male socket of the second battery connector on the battery is connected to the second battery The female base of the device has not been successfully engaged. Among them, it should be noted that the single charge pump has a path connection with both battery connectors. The I2C communication line comes from the main battery connector and is connected to the single charge pump and processor. The slave battery connector is connected to the single charge pump. ,I2C communication cannot be carried out between processors. As an example, I2C communication is also possible between the battery connector and a single charge pump and processor.

FIG. 7 is a flow chart of another battery connector snap-in detection method according to an exemplary embodiment. As shown in FIG. 7 , the battery connector snap-in detection method may include the following steps.

In step 701, obtain the voltage value collected by the ADC module in the connection detection module.

Optionally, a resistor component with a fixed resistance is connected in series between the ADC module and the female socket of the first battery connector, and the ADC path is grounded by snapping the male socket of the first battery connector, whereby the ADC can be The module collects the voltage value of the ADC channel so as to use the voltage value to detect whether the first battery connector is engaged.

In step 702, determine whether the connection detection module is grounded based on the voltage value collected by the ADC module.

It should be noted that in the embodiment of the present disclosure, the above-mentioned first condition and second condition are related to the size of the built-in pull-up resistor of the ADC module. For example, if the pull-up resistor built into the ADC module has the same resistance value as the above resistor component, then the first condition can be: the voltage value collected by the ADC module is half of the reference voltage VREF; the second condition can be: the voltage value collected by the ADC module The voltage value is the reference voltage VREF, that is, the voltage value collected by the ADC module is the same as the reference voltage VREF. In other words, the relationship between the resistance value of the built-in pull-up resistor of the ADC module and the above-mentioned resistor component can determine the first condition and the second condition, which can be set according to the actual situation. This disclosure does not specifically limit this.

In order to further improve the accuracy of detection, optionally, in some embodiments of the present disclosure, when comparing the voltage value collected by the ADC module with the preset reference voltage, a certain allowable error can be added, such as the allowable error The error can be ±10%.

range, and the voltage value collected by the ADC module falls within the range of VREF ±10%, it can be determined that the connection detection module is not grounded, and it can be determined personally that the first battery connector is not fastened properly. At this time, the charging power can be reduced, and Uploads information of battery connector failure to the operating system of the electronic device. If the voltage value collected by the ADC module does not fall within this

Within the range and does not fall within the range of VREF ±10%, it can be determined that the first battery connector is not engaged and an abnormal state is uploaded to the operating system of the electronic device. The abnormal state may be an abnormality in the charging circuit or a charging problem. The hardware components in the system are abnormal, or the charging chip status may be abnormal, etc. Therefore, the ADC module can be used to add judgment logic to the original software charging state machine for polling without increasing additional power consumption.

If the relevant information inside the battery can be obtained through I2C communication, it can be considered that the communication connection between the battery and the motherboard processor is normal. It can be determined that the male socket of the second battery connector on the battery and the female socket of the second battery connector are successfully engaged. Optionally, if the relevant information inside the battery cannot be obtained through I2C communication, it can be considered that the communication connection between the battery and the motherboard processor is abnormal, and it can be determined that the male socket of the second battery connector on the battery is connected to the second battery The female base of the device has not been successfully engaged.
