It should be noted that, all actions for acquiring signals, information or data in the present disclosure are performed under the condition of conforming to the corresponding data protection rule policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.

The charging control method provided by the disclosure is applied to a terminal, and a battery of the terminal adopts three connectors, as shown in fig. 1, and fig. 1 is a block diagram of a charging control circuit shown in an exemplary embodiment of the disclosure. The battery of the terminal comprises a battery cell and a fuel gauge, wherein the battery cell and the fuel gauge are connected through a circuit and are packaged in the battery to form a battery package (pack) end.

The battery pack end is connected with a charge pump on a mainboard of the terminal through three connectors, the charge pump is connected with a charger, the charge pump is used for rapidly charging the terminal, the three connectors are a first connector, a second connector and a third connector respectively, and the charge pump comprises a first charge pump, a second charge pump and a third charge pump.

One end of the first connector is connected with the first charge pump, the other end of the first connector is connected with a battery pack end and an integrated Power management circuit (Power MANAGEMENT IC, PMIC) end, the other end of the PMIC is connected with a main board of the terminal, and the main board comprises a terminal CPU and various modules of the terminal, such as a camera module, a WIFI module, a Bluetooth module, a display module, a control module, a touch screen module, a key module, a storage module and the like; one end of the second connector is connected with the second charge pump, and the other end of the second connector is connected with an electricity meter of the battery; one end of the third connector is connected with the third charge pump, and the other end of the third connector is connected with the pack end of the battery.

The first connector, the second connector and the third connector respectively read the voltage or the current of the pack end of the battery through an analog-digital converter (Analog to Digital Converter, ADC), and the fuel gauge reads the voltage of the battery cell through an I2C (Inter-INTEGRATED CIRCUIT) bus; the second connector is connected with the electricity meter, and the second connector can read the voltage of the battery cell through the I2C bus.

The terminal battery is designed into three connectors, so that the battery can support larger charging power, but under the scene of charging the terminal through a charger, the three connectors are easy to loose, break, tear and the like, and in order to avoid the charging risk caused by the break of one or more connectors, the states of the three connectors are detected at the moment of inserting the charger into the terminal or in the charging process through the charger.

Based on this, the present disclosure proposes a charge control method including the steps of: the states of the three connectors are detected at the moment the charger is inserted into the terminal or during charging by the charger. The states of the three connectors can be determined by the voltage of the pack end of the battery read by the ADC, the voltage of the battery cell read by the I2C bus, the starting voltage of the terminal system and the state of the charge pump.

And when the connector is detected to be in the disconnection state, controlling the fast charging protocol state machine to exit the fast charging mode, or limiting the charging current or the charging power of the charger. And under the condition that the connector is in the disconnection state, the quick charging mode is exited, or the charging current or the charging power of the charger is limited, so that the potential safety hazard during charging is avoided, and the charging safety of the battery with three connectors is ensured.

Referring to fig. 2, fig. 2 is a flowchart illustrating a charge control method according to an exemplary embodiment of the present disclosure. The method is performed by a terminal device, which may be, but is not limited to, a smart phone, a notebook computer, a desktop computer, a tablet computer, a smart speaker, a smart robot. The charge control method shown in fig. 2 includes the steps of:

In step S21, the states of the three connectors are detected at the moment the charger is inserted into the terminal or during charging by the charger.

In one embodiment, the first connector is a master connector, the second connector and the third connector are a slave connector 1 and a slave connector 2, respectively, the first charge pump is a master charge pump, and the second charge pump and the third charge pump are a slave charge pump 1 and a slave charge pump 2, respectively. How to detect the states of the master connector, the slave connector 1, and the slave connector 2, respectively, will be described later by taking this embodiment as an example.

For the main connector, in the case of the main connector being disconnected, the battery is disconnected from the main charge pump, and the battery is disconnected from the PMIC, at this time, the charger directly supplies power to the terminal motherboard through the PMIC, as shown in fig. 3, fig. 3 is a block diagram of a charge control circuit in the case of the main connector being disconnected, which is shown in an exemplary embodiment of the present disclosure. In order to ensure the charging safety, a quick charging protocol state machine needs to be controlled at the moment to enable the terminal to exit from a quick charging mode so as to avoid potential safety hazards during charging.

The detection mode of the main connector comprises the following steps: determining that the first connector is in a disconnected state when the difference between the first current and the second current, or the difference between the first current and the third current, is greater than a first threshold; the first current is the current of the first charge pump, the second current is the current of the second charge pump, and the third current is the current of the third charge pump. That is, when the current value of the slave charge pump 1 or the current value of the slave charge pump 2 is subtracted from the current value of the master charge pump, and the result is greater than the first threshold value, it is determined that the master connector is in the disconnected state. The current value of the charge pump is obtained by the ADC. The first threshold may be, but is not limited to, 1A.

The detection mode of the main connector further comprises the following steps: and in the charging process of the terminal through the charger, starting a detection thread to detect the states of the three connectors, and determining that the first connector is in a disconnection state under the condition that the first charge pump is in a disabled state and the second charge pump is in an enabled state. Because the terminal charges through the charger in-process, is firstly through main connector connection main charge pump charge, and then charges through from connector 1 connection slave charge pump 1, finally charges through from connector 2 connection slave charge pump 2, and under the normal charge condition, main charge pump is in enable state, and slave charge pump 1 is in enable state or disable state. That is, in the case where it is detected that the master charge pump is in the disabled state and the slave charge pump 1 is in the enabled state, it may be determined that the master connector is in the disconnected state.

With respect to the slave connector 1, in the case of disconnection from the connector 1, the battery is disconnected from the path of the slave connector 1, and the main board is disconnected from the path of the fuel gauge, as shown in fig. 4, fig. 4 is a block diagram of a charge control circuit in the case of disconnection from the connector 1, which is shown in an exemplary embodiment of the present disclosure. This may cause that the terminal system cannot correctly identify the current battery parameters, such as current, voltage, temperature, electric quantity, etc., so that the charging process may have dangerous hidden danger of overcharging, and at this time, the fast charging protocol state machine needs to be controlled to make the terminal exit the fast charging mode, so as to avoid the potential safety hazard during charging.

The detection method of the slave connector 1 includes: determining that the second connector is in a disconnected state when the number of failures of the fuel gauge to continuously read and write the register is greater than a specified number, or when the first voltage is greater than a threshold voltage; the first voltage is the battery voltage read from the second charge pump, and the threshold voltage is the starting voltage of the terminal system. That is, in the case where the number of failures of the continuous reading and writing register of the fuel gauge is greater than the specified number, that is, it is determined that the I2C bus of the fuel gauge is not in communication, it is further determined that the slave connector 1 is in the disconnected state, the specified number may be, but is not limited to, 10 times, which may be obtained based on human experience, or may be obtained in other possible manners, which the present disclosure is not limited to. Or the battery voltage read out from the ADC of the charge pump 1 can be compared with the starting voltage of the terminal system; assuming that the battery in the present disclosure is designed as a dual battery cell for achieving the preset charging power, the starting voltage of the terminal system is 3V, the threshold voltage is 3v×2=6v, and if the battery voltage read from the ADC of the charge pump 1 is less than 6V, it is determined that the slave connector 1 is in the disconnected state.

With respect to the slave connector 2, in the case of disconnection from the connector 2, the battery is disconnected from the path of the slave connector 2 as shown in fig. 5, and fig. 5 is a block diagram of a charge control circuit in the case of disconnection from the connector 2 as shown in an exemplary embodiment of the present disclosure. This may cause that the fast charging protocol policy of the terminal system is inconsistent with the hardware capability of the charging circuit, and in order to charge safely, the charging current and the charging power of the charger need to be limited at this time, so as to avoid potential safety hazards during charging.

The detection method of the slave connector 2 includes: determining that the third connector is in a disconnected state if the second voltage is greater than the threshold voltage; the second voltage is the battery voltage read from the third charge pump, and the threshold voltage is the start-up voltage of the terminal system. Comparing the battery voltage read from the ADC of the charge pump 2 with the start-up voltage of the terminal system; assuming that the battery in the present disclosure is designed as a dual battery cell for achieving the preset charging power, the starting voltage of the terminal system is 3V, the threshold voltage is 3v×2=6v, and if the battery voltage read from the ADC of the charge pump 2 is less than 6V, it is determined that the slave connector 2 is in the disconnected state.

In step S22, when it is detected that the connector is in the disconnected state, the fast charging protocol state machine is controlled to exit the fast charging mode, or the charging current or the charging power of the charger is limited.

And when the first connector or the second connector is detected to be in a disconnection state, controlling the fast charging protocol state machine to exit the fast charging mode, and when the third connector is detected to be in a disconnection state, limiting the charging current and the charging power of the charger. That is, the fast charge protocol state machine is controlled to exit the fast charge mode when the master connector or the slave connector 1 is detected in the disconnected state, and the charging current and the charging power of the charger are limited when the slave connector 2 is detected in the disconnected state.

In summary, the charging control method provided by the present disclosure includes: the method comprises the steps that a battery of a terminal is connected with a charge pump on a terminal main board through three connectors, the charge pump is connected with a charger, states of the three connectors are detected at the moment that the charger is inserted into the terminal or in the charging process of the charger, and when the fact that the connectors are in an off state is detected, a fast charging protocol state machine is controlled to exit a fast charging mode or charging current or charging power of the charger is limited; the method has the advantages that when the situation that the connectors are in the disconnection state is detected, the quick charging mode is exited, or the charging current or the charging power of the charger is limited, the charging power is improved, meanwhile, the potential safety hazard during charging is avoided, and the charging safety of the battery with the three connectors is ensured.
