The following describes a charging circuit and a charging control method for a split-screen electronic device according to an embodiment of the present application with reference to the drawings.
The embodiment of the application provides a split screen electronic equipment charging circuit, and aims to solve the problems that in the related art, when split screen electronic equipment is charged, charging currents of a screen end and a host end are controlled, and flexibility is poor.
The split screen electronic equipment charging circuit provided by the embodiment of the application is connected with a first electricity meter at the host end and a second electricity meter in the screen end respectively through a charging control loop arranged at the host end of the electronic equipment, so that the current electricity values of a first battery and a second battery in the host end and the screen end are obtained in real time through the first electricity meter and the second electricity meter, and then the charging currents of the first battery and the second battery are controlled, so that the charging currents of the host end and the screen end are intelligently controlled according to the current electricity values of the host end and the screen end, and the flexibility of controlling the charging currents of the host end and the screen end is improved.
Fig. 1 is a structural view of a charging circuit for a split-screen electronic device according to an embodiment of the present application.
In the embodiment of the application, the split-screen electronic device may include a split-screen mobile phone, a split-screen palm computer, and the like. The split screen electronic equipment comprises a host end and a screen end, and the host end and the screen end can be separated.
As shown in fig. 1, the split-screen electronic device charging circuit includes: the charging control circuit 110, the first electricity meter 120, and the second electricity meter 130.
The charging control circuit 110 is arranged at a host end of the split-screen electronic device; the first electricity meter 120 is disposed at the host end, connected to the first battery at the host end, and configured to obtain a current first electric quantity value of the first battery; the second electricity meter 130 is disposed at the screen end of the split screen electronic device, and is connected to the screen end second battery, for obtaining a current second electric quantity value of the second battery.
In this embodiment, the input end of the charging control loop 110 is connected to the output end of the charging adapter, and the first feedback end of the charging control loop 110 is connected to the output end of the first electricity meter 120, so as to obtain the first electric quantity value of the first battery at the host end. The second feedback end of the charging control loop 110 is connected to the output end of the second electricity meter 130 to obtain a second electric quantity value of the second battery at the screen end. A first output terminal of the charging control circuit 110 is connected to a charging terminal of a first battery at the host terminal, and a second output terminal of the charging control circuit 110 is connected to a charging terminal of a second battery at the screen terminal.
The charging control circuit 110 is configured to control current values output by the first output terminal and the second output terminal according to the obtained first electric quantity value output by the first electric quantity meter 120 and the obtained second electric quantity value output by the second electric quantity meter 130.
In this embodiment, when the split-screen electronic device is charged by the charging adapter, the charging adapter outputs current to the input terminal of the charging control circuit 110 through the output terminal. In the charging process, the first electricity meter 120 may detect a current first electric quantity value of the first battery at the host end in real time and output the current first electric quantity value to the first feedback end of the charging control loop 110 through the output end, and the second electricity meter 130 may detect a current second electric quantity value of the second battery at the screen end in real time and output the current second electric quantity value to the second feedback end of the charging control loop 110 through the output end. Thus, the charging control circuit 110 obtains a current first electric quantity value of the host terminal and a current second electric quantity value of the screen terminal from the first electric quantity meter 120 and the second electric quantity meter 130 through the first feedback terminal and the second feedback terminal, and controls the current values output by the first output terminal and the second output terminal according to the first electric quantity value and the second electric quantity value, that is, controls the charging current distributed to the host terminal and the screen terminal.
For example, the charging currents of the host side and the screen side may be made to be the same by control, or the charging currents of the host side and the screen side may be made to be in a preset proportion by control, and so on.
In the related art, when the split-screen electronic device is charged, the charging current of the host side and the charging current of the screen side cannot be intelligently controlled, so that the charging completion time of the host side and the charging completion time of the screen side are usually inconsistent, and the whole cruising ability of the split-screen electronic device is poor.
In this embodiment, the charging control circuit 110 can control the charging current distributed to the host side and the screen side according to the first electric quantity value and the second electric quantity value, so that the time taken for the host side battery to reach the rated capacity is the same as the time taken for the screen side battery to reach the rated capacity.
Specifically, the charge control loop 110 may calculate a difference between a rated capacity of the first battery and the first electric quantity value to obtain a first to-be-charged quantity value, and calculate a difference between a rated capacity of the second battery and the second electric quantity value to obtain a second to-be-charged quantity value. In order to enable charging completion time of the host end and the screen end to be the same, the first value to be charged and the second value to be charged are divided by the remaining charging time respectively to obtain a current value output by the first output end and a current value output by the second output end. Therefore, under the condition that the residual charging time is constant, the charging currents of the first battery and the second battery when the first battery and the second battery are charged simultaneously can be calculated according to the first value to be charged and the second value to be charged.
The size of the remaining charging time can be determined according to actual conditions. For example, if the charging time length of single charging is preset, the remaining charging time is equal to the difference between the set charging time length and the charged time length; or, the remaining charging time can also be determined according to the current first battery and the second batteryThe difference between the value of the battery's charge and its nominal capacity value, and the maximum achievable charging current, are determined. For example, if the first to-be-charged value of the first battery is 2000mAh, the second to-be-charged value of the second battery is 1000mAh, and the maximum charging current achievable by the charging loop of the first battery is 1A, and the maximum charging current achievable by the charging loop of the second battery is 0.8A, the remaining charging time of the first battery is
The remaining charge time of the second battery is
In order to complete the charging of the first battery and the second battery at the same time, the current remaining charging time may be determined to be 2 h.
For example, the rated capacity of the first battery is 3000mAh, and the first electric quantity value is 1000 mAh; the second battery has a rated capacity of 2000mAh and a second capacity value of 1000 mAh. Then the first to-be-charged value of the first battery is 2000mAh and the second to-be-charged value of the second battery is 1000 mAh. If the host end and the screen end are required to finish charging simultaneously within the remaining 2 hours, the charging current of the host end is
Charging current at screen end is
That is, the charging control loop 110 controls the first output terminal to output a current of 1.0A to the charging terminal of the first battery, and controls the second output terminal to output a current of 0.5A to the charging terminal of the second battery.
In this embodiment, according to the first electric quantity value and the second electric quantity value, the charging currents of the host side and the screen side can be intelligently distributed, so that the host side and the screen side can be charged simultaneously, and the overall cruising ability of the split screen electronic device is greatly improved.
The split screen electronic equipment charging circuit comprises a charging control loop, a charging control loop and a charging current control loop, wherein the charging control loop is connected with an electricity meter for detecting the current electric quantity of a host end battery and an electricity meter for detecting the current electric quantity of the screen end battery respectively, so as to obtain the current electric quantity value of the host end and the current electric quantity value of the screen end, and further control the charging current distributed to the host end and the screen end, thereby realizing the charging current of the intelligent control host end and the screen end, and improving the flexibility of controlling the charging current of the host end and the screen end.
In a possible implementation manner of the embodiment of the present application, the second feedback end of the charging control loop 110 may be connected to the output end of the second electricity meter 130 in the screen end through a first interface, and the second output end of the charging control loop 110 is connected to the second charging end in the screen end through a second interface.
The first interface and the second interface are physical interfaces.
Further, in a possible implementation manner of the embodiment of the present application, the second feedback terminal of the charging control loop 110 may be connected to the output terminal of the second electricity meter 130 through a first wireless link, and the second output terminal of the charging control loop 110 may be connected to the charging terminal of the second battery through a second wireless link.
That is, the second electricity meter 130 may wirelessly transmit information of the second amount of electricity to the charge control circuit 110, and the charge control circuit 110 may wirelessly charge the second battery.
In practical application, the charging adapter may be used to charge the split-screen electronic device, and in a possible implementation manner of the embodiment of the present application, an input end of the charging control circuit 110 at the host end may be connected to an output end of the charging adapter through the first charging interface. The first charging interface can be a Micro USB interface, a Type-C interface and the like.

In this embodiment, a first current value of a first charging loop connected to a first battery of the host end and a second current value of a second charging loop connected to a second battery of the screen end may be controlled according to a current first current value of the host end and a current second current value of the screen end, respectively, so as to charge the host end according to the first current value and charge the screen end according to the second current value. Thus, the charging current distributed to the host side and the screen side is flexibly controlled.
For example, the charging currents of the host side and the screen side may be made to be the same by control, or the charging currents of the host side and the screen side may be made to be in a preset proportion by control, and so on.
In the related art, when the split-screen electronic device is charged, the charging current of the host side and the charging current of the screen side cannot be intelligently controlled, so that the charging completion time of the host side and the charging completion time of the screen side are usually inconsistent, and the whole cruising ability of the split-screen electronic device is poor.
In this embodiment, the charging currents distributed to the host side and the screen side may be controlled according to the first electric quantity value and the second electric quantity value, so that the time taken for the host side battery to reach the rated capacity is the same as the time taken for the screen side battery to reach the rated capacity.
Specifically, a difference value between a first rated capacity of a first battery at a host end and a first electric quantity value is calculated to obtain a first value to be charged of the battery at the host end, a difference value between a second rated capacity of a second battery at a screen end and a second electric quantity value is calculated to determine a second value to be charged of the battery at the screen end.
In order to enable the charging completion time of the host end and the screen end to be the same, the first value to be charged and the second value to be charged are divided by the remaining charging time respectively to obtain a first current value of the host end and a second current value of the screen end, the first battery of the host end is charged according to the first current value, the second battery of the screen end is charged according to the second current value, the time for the battery of the host end to reach the first rated capacity is the same as the time for the battery of the screen end to reach the second rated capacity, and the charging completion time of the host end and the screen end is the same. The remaining charging time may be determined according to actual conditions, and details thereof are described in the above embodiments.
For example, the rated capacity of the first battery is 3000mAh, and the first electric quantity value is 1000 mAh; the second battery has a rated capacity of 2000mAh and a second capacity value of 1000 mAh. Then the first to-be-charged value of the first battery is 2000mAh and the second to-be-charged value of the second battery is 1000 mAh. If the host end and the screen end are required to finish charging simultaneously within the remaining 2 hours, the charging current of the host end is
Charging current at screen end is
That is, the charging control loop 110 controls the first output terminal to output a current of 1.0A to the charging terminal of the first battery, and controls the second output terminal to output a current of 0.5A to the charging terminal of the second battery.
In this embodiment, the charging currents distributed to the host side and the screen side are controlled according to the first rated capacity and the first electric quantity value, and the second rated capacity and the second electric quantity value, so that the host side and the screen side complete charging at the same time, and the overall cruising ability of the split-screen electronic device is greatly improved.
