Fig. 1 shows a schematic diagram of an exemplary system architecture to which the charge control scheme of the embodiments of the present disclosure may be applied.

As shown in fig. 1, the system architecture may include an electronic device 11 and an adapter 12. In one embodiment of the present disclosure, the electronic device 11 may be in wired connection with the adapter 12, charging the electronic device 11 in a wired manner. In yet another embodiment of the present disclosure, the electronic device 11 may be wirelessly charged using the adapter 12.

In an exemplary embodiment of the present disclosure, the electronic device 11 may include, but is not limited to, a mobile phone, a tablet computer, a smart wearable device, a notebook computer, and the like, and the present disclosure does not limit the type of the electronic device 11.

Referring to fig. 1, the electronic device 11 may include a Microcontrollerunit (MCU) 111 and an Application Processor (AP) 112. In some embodiments of the present disclosure, the application processor 112 stores one kind of fast charging logic, for example, a low temperature fast charging logic, and the micro control unit 111 stores another kind of fast charging logic, for example, a normal temperature fast charging logic other than the low temperature fast charging logic. During the charging process, if the charging logic stored in the mcu 111 and the application processor 112 needs to be switched, the operation of exiting the fast charging and then entering the fast charging may be performed.

Specifically, in the case where the electronic device 11 is electrically connected to the adapter 12, the electronic device 11 may detect the battery temperature, and when the battery temperature is between a first temperature threshold (e.g., 12 °) and a second temperature threshold (e.g., 16 °), the battery may be charged in the first charging mode stored in the micro control unit 111. If the battery temperature drops to the first temperature threshold during the charging process, the charging mode is switched from the first charging mode to the second charging mode, and the second charging mode is switched to the third charging mode stored in the application processor 112, so as to continue charging the electronic device.

The charging current corresponding to the first charging mode is greater than the charging current corresponding to the third charging mode, and the charging current corresponding to the third charging mode is greater than the charging current corresponding to the second charging mode. In some embodiments, the first charging mode and the third charging mode correspond to a fast charging type (i.e., a fast charging type), and the second charging mode corresponds to a general charging type (i.e., a general charging type).

In addition, since the time taken for the whole process of switching from the first charging mode to the third charging mode via the second charging mode is short, in order to make the charging icons viewed by the user consistent during this time, in other embodiments, starting from the switching from the first charging mode to the second charging mode, the status flag generated due to the disconnection of the power line (vbus) is cleared within a predetermined time, after the predetermined time elapses, the quick charging start flag is cleared, and the flag displaying the quick charging icon is configured to be activated, so as to control the electronic device 11 to display the quick charging icon before entering the third charging mode.

It should be understood that the mcu 111 and the application processor 112 may each have one or more fast charge logic stored therein, and the fast charge logic may be combined into a single charge logic set. In this case, the above exemplary scheme may be adopted to implement switching between any two fast charging logics in the set.

Furthermore, in some embodiments of the present disclosure, the fast charge logic is typically run by the micro control unit 111 to enable fast charging of the electronic device 11. When it is necessary to run the charging logic on the application processor 112, the micro control unit 111 may obtain the charging logic from the application processor 112 and implement the charging operation of the electronic device 11 based on the charging logic.

In this case, when the detected battery temperature is between 12 ° and 16 °, the electronic device may be charged in a first charging mode, which may include, for example, performing constant current charging of 5A.

And S56, if the temperature of the battery is reduced to the first temperature threshold value, switching the charging mode of the electronic equipment from the first charging mode to the second charging mode, and switching the charging mode from the second charging mode to the third charging mode so as to continuously charge the electronic equipment.

In an exemplary embodiment of the present disclosure, the first, second, and third charging modes are three different charging modes. Specifically, the charging current corresponding to the first charging mode is greater than the charging current corresponding to the third charging mode, and the charging current corresponding to the third charging mode is greater than the charging current corresponding to the second charging mode.

In addition, the first charging mode and the third charging mode may belong to a first charging type, corresponding to a fast charging type; the second charging mode belongs to a second charging type and corresponds to a general charging mode.

According to some embodiments of the present disclosure, logic codes corresponding to the first charging mode are stored in the micro control unit, and logic codes corresponding to the third charging mode are stored in the application processor.

In the process of charging the electronic device in the first charging mode in step S54, if it is detected that the battery temperature has dropped to the first temperature threshold, the first charging mode is switched to the second charging mode, and the second charging mode is switched to the third charging mode to continue charging the electronic device.

Under the condition that the first charging mode corresponds to the quick charging mode A, the second charging mode corresponds to the normal charging mode, and the third charging mode corresponds to the quick charging mode B, if the temperature of the battery is reduced to a first temperature threshold value, the quick charging switch is switched off, the process of quitting the quick charging operation is executed, and the quick charging mode A is switched to the normal charging mode. In this case, the battery temperature falls within the range of the fast charging mode B, the application processor sends an execution command of the fast charging mode B to the micro control unit, the micro control unit executes the operation of the fast charging mode B, switches from the normal charging mode to the fast charging mode B, and enters the fast charging again for charging.

For example, the first temperature threshold is 12 °, the charging current for the first charging mode is 5A, and the charging current for the third charging mode is 1.9A. In this case, when the battery temperature falls to 12 °, the charging current is switched from 5A to the charging current for normal charging (e.g., 1A), and then the charging current is switched from 1A to 1.9A again.

It is understood that the third charging mode may correspond to a lower temperature charging mode. By adopting the exemplary scheme of the disclosure, on one hand, switching between charging logics stored in different positions can be realized, and on the other hand, a charging strategy with a lower temperature can be realized.

In the process of switching from the fast charge mode a to the fast charge mode B via the normal charge mode, a problem that the charging icons displayed by the electronic device are inconsistent may occur, that is, a problem that the fast charge icon is displayed first, then the normal charge icon is displayed, and then the fast charge icon is displayed may occur. In addition, due to the operation of quitting the quick charging, the problem that the power line is disconnected at the moment of quitting the quick charging also exists, so that the charging icon cannot be displayed. These all cause a problem that the charging icon display effect is not good.

In order to solve the problem of poor display effect of the charging icon, according to some embodiments of the present disclosure, on the one hand, when the electronic device is charged in the first charging mode and the third charging mode, a charging icon corresponding to the first charging type, that is, a quick charging icon, is displayed on the electronic device. On the other hand, in the process of switching the charging mode of the electronic device from the first charging mode to the second charging mode and from the second charging mode to the third charging mode, when the electronic device is charged in the second charging mode, the electronic device is controlled to display a charging icon corresponding to the first charging type.

Specifically, the status flag generated due to disconnection of the power supply line is cleared for a predetermined time (e.g., 350ms) from the time when the charging mode of the electronic device is switched from the first charging mode to the second charging mode. After the preset time, the electronic equipment clears the charging start mark corresponding to the first charging type, and configures the mark for displaying the charging icon corresponding to the first charging type to be activated so as to control the electronic equipment to display the charging icon corresponding to the first charging type.

It should be understood that the charging icon corresponding to the first charging type is continuously displayed on the electronic device before the charging start flag is cleared.

For example, when the battery temperature drops to 12 °, the fast charge switch is turned off, and a power line interruption occurs, but at this time, the charge start flag is not cleared, and the fast charge icon on the electronic device does not disappear. In this case, a delay of 350ms is used to handle the operation associated with the power line interruption and to clear the status flag generated due to the disconnection of the power line. After 350ms, the electronic device clears the charging start flag and configures the flag displaying the quick charging icon to be activated, and at this time, the quick charging icon is still displayed on the electronic device although the electronic device is not in the quick charging mode.

In order to distinguish the case where the adapter is powered off or the electronic device is disconnected from the adapter when the power cord is disconnected, in other embodiments of the present disclosure, a monitoring thread may be configured to monitor whether the power cord is disconnected due to the power failure of the adapter or the disconnection of the electronic device from the adapter.

Specifically, the electronic device may obtain the voltage on the power line upon detecting that the battery temperature has dropped to a first temperature threshold.

If the voltage on the power cord is less than a voltage threshold (e.g., 2V), indicating that the adapter is powered off or that the electronic device is disconnected from the adapter, in which case the charging icon corresponding to the first charging type is displayed on the electronic device is cleared.

And if the voltage on the power line is greater than or equal to the voltage threshold, executing the operation to control the electronic equipment to display a charging icon corresponding to the first charging type in the process of switching the charging mode of the electronic equipment from the first charging mode to the second charging mode and charging by adopting the second charging mode.

According to some embodiments of the present disclosure, when step S52 detects that the battery temperature is between the first temperature threshold and the third temperature threshold, the electronic device is charged in the third charging mode. Wherein the third temperature threshold is less than the first temperature threshold.

For example, the first temperature threshold value is 12 ° and the third temperature threshold value is 5 °. At this time, the third charging mode is directed to the charging mode when the battery temperature is low, specifically, the charging current may be configured to be 1.9A, and the corresponding charging curve standard is 1.9A to 4.2V. In addition, the charging current can be configured to be 1.3A, and the corresponding charging curve standard is 1.3A and 4.4V.

After the electronic equipment is charged in the third charging mode, if the temperature of the battery is detected to rise to the first temperature threshold value, the charging mode of the electronic equipment is switched from the third charging mode to the second charging mode, and the second charging mode is switched to the first charging mode, so that the electronic equipment is continuously charged. This process is similar to the process of step S56 and will not be described in detail herein.

According to other embodiments of the present disclosure, when it is detected in step S52 that the battery temperature is less than the third temperature threshold, the electronic device is charged in the second charging mode.

For example, when the battery temperature is less than 5 °, the charging performance of the battery is greatly affected, and at this time, the electronic device is charged in a low current mode of a general charge.

According to still other embodiments of the present disclosure, after the electronic device is charged in the first charging mode in step S54, if the battery temperature rises to the fourth temperature threshold, the charging mode of the electronic device is switched from the first charging mode to the fourth charging mode to continue charging the electronic device.

For example, when the battery temperature is detected to be between 12 ° and 16 °, the constant current charging is performed using 5A. In this case, if the battery temperature rises to the fourth temperature threshold, for example, to 18 °, the charging mode is switched to the fourth charging mode, for example, constant current charging with 6.5A is performed.

Fig. 6 shows a logic diagram of a charging state according to another embodiment of the present disclosure, in which codes corresponding to 5 ° to 12 ° of charging logic may be stored in the application processor, and codes corresponding to the remaining charging logic may be stored in the micro control unit.

Referring to fig. 6, in the case where the battery temperature is 16 ° to 42.5 °, the charging in the normal state is performed with the charging current of 6.5A. In the case where the battery temperature is greater than 42.5 °, the charging in the high temperature state 0 is performed with a charging current of 4A. When the battery temperature is less than 16, charging in a relatively cold state is performed with a charging current of 5A. In addition, when the temperature of the battery is less than 12 degrees, the battery can enter a cold temperature state of 5 degrees to 12 degrees.

In the cold state, when the battery temperature is 12 ° to 16 °, the charging is continued with the charging current of 5A. In the case where the battery temperature is greater than 18 °, the normal state is entered, and charging is performed with a charging current of 6.5A. And when the temperature of the battery is less than 12 degrees, the battery exits from the quick charging mode and is charged in the normal charging mode.

In the cold state, when the battery temperature is 5 ° to 12 °, the battery can be charged with a charging current of 1.9A or 1.3A as described above. And when the temperature of the battery is less than 5 degrees, the battery exits from the quick charging mode and is charged in the normal charging mode.

In the low temperature state 0, in the case where the battery temperature is less than 42.5 °, the charging with the charging current of 4A is continued. When the battery temperature is higher than 42.5 °, the high temperature state 0 is entered, and the charging with the charging current of 4A is continued.

In the high temperature state 1, charging is performed with a charging current of 3A when the battery temperature is 41.5 ° to 43.5 °. When the battery temperature is less than 41.5 °, the system enters a low temperature state 1, and is charged with a charging current of 4A. When the battery temperature is higher than 43.5 °, the high temperature state 2 is entered, and charging is performed with a charging current of 2A.

In the low temperature state 1, when the battery temperature is 40 ° to 41.5 °, the battery is charged with a charging current of 4A. In the case where the battery temperature is less than 40 °, the low temperature state 0 is entered, and charging is performed with a charging current of 4A. In the case where the battery temperature is higher than 43 °, the high temperature state 1 is entered, and charging is performed with a charging current of 3A.

In the low temperature state 2, when the battery temperature is 41.5 ° to 42 °, the charging is performed with a charging current of 3A. When the battery temperature is less than 41.5 °, the system enters a low temperature state 1, and is charged with a charging current of 4A. In the case where the battery temperature is higher than 43.5 °, the high temperature state 2 is entered, and charging is performed with a charging current of 2A.

It should be understood that the various temperature thresholds, charging currents, etc. shown in fig. 6 are merely exemplary descriptions and should not be taken as limitations of the present disclosure.

In step S708, if the battery temperature is between 5 ° and 12 °, the charging is performed using a charging logic of 5 ° to 12 °.

In step S710, if the battery temperature is in the range of 12 ° to 16 °, charging is performed with a charging current of 5A.

In step S712, it is determined whether the battery temperature has dropped below 12 °, and if not, step S710 is continued; if it falls below 12 deg., step S714 is executed.

In step S714, the quick charge switch is turned off, that is, the quick charge is exited. In step S716, a power line interrupt is generated. In step S718, a delay of 350ms is performed to handle the operation associated with the power line interrupt. In step S720, the power line monitoring thread is turned on.

In step S722, it is determined whether the power line voltage is greater than 2V, and if so, it indicates that the electronic device and the adapter still remain electrically connected, and at this time, no operation is performed; if the voltage is less than 2V, it indicates that the electronic device is electrically disconnected from the adapter, at this time, step S724 is executed, the electronic device clears the pseudo fast charging flag, and the charging is finished.
