For electronic devices with full screen functions, such as folding screen mobile phones and tablet computers, the power consumption of the electronic devices is high, so that the devices need to be provided with batteries with large capacity, and the battery capacity can be expanded in a mode of connecting a plurality of batteries in parallel. When an electronic device has a plurality of batteries and a plurality of charging chips, how to dynamically adjust the current of the plurality of charging chips so as to shorten the charging time and improve the charging efficiency of the electronic device is a problem to be solved currently.

Based on this, the embodiment of the application proposes a charging control method that is applicable to an electronic device having a plurality of charging chips.

In an example, the charge management module 111 controls the opening and closing states of the switch module 116 through the first control module 112 or the second control module 113.

In one example, when the electronic device starts to charge, the charge management module 111 controls the switch module 116 to be in an off state, and at this time, the first charging chip 114 charges the first battery 1171, and the second charging chip 115 charges the second battery 1172. When the first battery 1171 is fully charged, the charging management module 111 controls the switch module 116 to be closed through the first control module 112, so that the first charging chip 114 charges the second battery 1172.

It is to be understood that the connection relationship of the internal devices of the electronic apparatus shown in fig. 7 is only used as an example, and does not constitute a specific limitation on the electronic apparatus 100 in which the technical solution of the present application may be implemented. In other embodiments of the present application, electronic device 100 may include more or fewer components than shown in FIG. 7, or may combine certain components, or split certain components, or a different arrangement of components. The components shown in fig. 7 may be implemented in hardware, software, or a combination of hardware and software.

In some embodiments, the charge management module 111 may directly control the first and second charge chips 114 and 115.

The functions of some of the modules or devices in the electronic device 100 are described below.

In some embodiments, the charge management module 111 is configured to adjust the input current of the two charging chips according to the charger 102 capability in the event that the charger 102 capability is determined. For example, based on fig. 7, the charge management module 111 may allocate an input current of 1.5A to the first charging chip 114 and an input current of 0.5A to the second charging chip 115 based on the output current (ibus=2a) of the charger 102 when determining that the charging parameter of the charger 102 is [5v,2A ].

In some embodiments, the charging management module 111 is configured to adjust input currents of the plurality of charging chips according to charging efficiency information of the plurality of charging chips in a case where charging efficiency information of the plurality of charging chips is determined. Specifically, the charging management module 111 adjusts the input currents of the plurality of charging chips according to the charging efficiency information of the plurality of charging chips and the charging parameters of the charger 102.

For example, based on fig. 7, when the charge management module 111 determines that the charge efficiency information of the first charging chip 114 and the second charging chip 115 is as shown in fig. 6 and the charge parameter of the charger 102 is [9V,2A ], 1A (ibus_1=1a) may be allocated to the first charging chip 114 and 1A (ibus_2=1a) may be allocated to the second charging chip 115 and 1A (ibus_2=1a) may be allocated to the input current value corresponding to the highest charge efficiency point of the second charging chip 115 under the current charge condition based on the output current (ibus=2a) of the charger 102 and the charge efficiency curve of the charging chip corresponding to the output voltage (vbus=9v) of the charger 102 shown in fig. 6.

In some embodiments, the charge management module 111 is configured to regulate the current of the plurality of charging chips in the event that the real-time temperatures of the plurality of batteries are determined. Specifically, the charge management module 111 adjusts the current of the plurality of charging chips according to the real-time temperatures of the plurality of batteries and the charging parameters of the charger 102.

Illustratively, based on fig. 7, the charge management module 111 reduces the current of the first charging chip upon determining that the temperature of the first battery 1171 is greater than the first threshold; or the charge management module 111 increases the current of the first charging chip upon determining that the temperature of the first battery 1171 is less than the second threshold. The charge management module 111 reduces the current of the second charging chip upon determining that the temperature of the second battery 1172 is greater than the third threshold; or the charge management module 111 increases the current of the second charging chip upon determining that the temperature of the second battery 1172 is less than the fourth threshold.

In some embodiments, the charging management module 111 is configured to adjust the current of the plurality of charging chips according to the system temperature in a case where the system temperature of the electronic device 100 is determined. The system temperature of electronic device 100 includes the temperature of one or more devices (or modules) in energy consuming system 120, such as the temperature of processor 121, the temperature of display 122, and the like. Specifically, the charge management module 111 adjusts the current of the plurality of charging chips according to the temperature of the energy consumption system 120 and the charging parameters of the charger 102.

Illustratively, the charge management module 111 decreases the current of the first and/or second charging chips upon determining that the temperature of the processor 121 is greater than the fifth threshold; or the charge management module 111 increases the current of the first and/or second charging chips upon determining that the temperature of the processor 121 is less than the sixth threshold.

Illustratively, the charge management module 121 reduces the current of the first and/or second charging chips upon determining that the temperature of the display screen 122 is greater than the seventh threshold; or the charging management module 121 increases the current of the first charging chip and/or the second charging chip when it is determined that the temperature of the display screen 121 is less than the eighth threshold.

When the input currents of the plurality of charging chips are adjusted, the sum of the input currents of the plurality of charging chips is smaller than or equal to the charging current of the charger, for example, (ibus_1+ibus_2) +.ibus shown in fig. 7. It should be further noted that, when adjusting the output currents of the plurality of charging chips, the maximum value of the output current of each charging chip is also limited by the maximum charging current of the corresponding battery, for example, if the first charging chip 114 charges the first battery 1171 in fig. 7, the output current (ichg_1) of the first charging chip 114 is limited by the maximum charging current of the first battery 1171.

In some embodiments, the charging management module 111 is configured to adjust the current of the plurality of charging chips according to the ambient temperature in case that the ambient temperature of the electronic device 100 is determined. Ambient temperature affects the maximum charge current of the battery. Illustratively, based on fig. 7, the charge management module 111 reduces the current of the first and/or second charging chips when it is determined that the ambient temperature of the electronic device 100 falls from a first temperature interval (e.g., 10 ℃,45 ℃) to a second temperature interval (e.g., 0 ℃,10 ℃). The charge management module 111 increases the current of the first and/or second charging chips upon determining that the ambient temperature of the electronic device 100 increases from the second temperature interval to the first temperature interval.

It will be appreciated that the ambient temperature may affect the system temperature and battery temperature of the electronic device, but that the increase in system temperature may also result from other reasons, such as the user operating behavior of running a game while charging. The increase in battery temperature may also result from other causes, such as a mismatch between the charger and the device, etc.

In some embodiments, the charging management module 111 is configured to adjust the current of the plurality of charging chips according to the charging voltages of the plurality of batteries and the maximum charging voltage of the plurality of batteries in a case where the charging voltages of the plurality of batteries are determined. Illustratively, based on fig. 7, the charge management module 111 decreases the current of the first charging chip 114 upon determining that the current charging voltage of the first battery 1171 is greater than the maximum charging voltage of the first battery 1171; or determining that the present charge voltage of first battery 1171 is less than the maximum charge voltage of first battery 1171, the current of first charging chip 114 may be increased.

In some embodiments, the charging management module 111 is configured to adjust the current of the plurality of charging chips according to the charging currents of the plurality of batteries and the maximum charging current of the plurality of batteries in a case where the charging currents of the plurality of batteries are determined.

In some embodiments, after the charger 102 is connected to the charging interface of the electronic device, the charger 102 is configured to send charging parameters of the charger 102 to the charging management module 111. In some embodiments, the electronic device 100 further includes a charger detection chip for reporting the charging parameters of the charger 102 to the charging management module 111. In some embodiments, the charging management module 111 may obtain the charging parameters of the charger 102 through the first charging chip 114 or the second charging chip 115, for example, the charging management module 111 sends a request to the first charging chip 114 or the second charging chip 115 to obtain the charging parameters of the charger 102, where the first charging chip 114 and the second charging chip 115 have the function of charger detection.

In some embodiments, the charge management module 111 is configured to generate current control parameters to the plurality of control modules, the current control parameters being configured to regulate the current of the plurality of charging chips. The current control parameters include input current or output current of the charging chips on different charging paths.

In one example, the charge management module 111 issues a first current control parameter to the first control module 112, the first current control parameter including an input current ibus_1 and/or an output current ichg_1 of the first charging chip 114, and the first control module 112 adjusts the input current or the output current of the first charging chip 114 according to the first current control parameter.

In some embodiments, the charging management module 111 is configured to issue a switch control parameter to the first control module 112 or the second control module 113, where the switch control parameter is configured to control the open/close state of the switch module 116.

In one example, the switch module 116 is in an off state, the first charging chip 114 charges the first battery 1171, the second charging chip 115 charges the second battery 1172, and the charging paths are independent of each other.

In one example, the switch module 116 is in a closed state, the first charging chip 114 may charge the first battery 1171 and the second battery 1172 simultaneously, and the second charging chip 114 may charge the first battery 1171 and the second battery 1172 simultaneously.

In one example, when the first battery 1171 is fully charged, the charging management module 111 issues the switch control parameter to the first control module 112, so that the first control module 112 controls to close the switch module 116, so that the first charging chip 114 can charge the second battery 1172 that is not fully charged, and the charging efficiency of the device is improved.

In an example, when the second battery 1172 is fully charged, the charging management module 111 issues the switch control parameter to the second control module 113, so that the second control module 113 controls to close the switch module 116, so that the second charging chip 115 can charge the first battery 1171 that is not fully charged, and the charging efficiency of the device is improved.

In an example, when the first charging chip 114 fails and the first battery 1171 is not fully charged yet, the charging management module 111 issues the switch control parameter to the second control module 115 so that the second control module 113 controls to close the switch module 116, so that the second charging chip 115 can charge the first battery 1171, and a problem that the first battery 1171 cannot be fully charged due to the failure of the first charging chip 114 can be avoided.

In an example, when the second charging chip 115 fails and the second battery 1172 is not fully charged yet, the charging management module 111 issues the switch control parameter to the first control module 112, so that the first control module 112 controls to close the switch module 116, and thus the first charging chip 114 can charge the second battery 1172, so that the problem that the second battery 1172 cannot be fully charged due to the failure of the second charging chip 115 can be avoided.
