In fig. 1(a), the charging interfaces correspond to the charging loops one by one, the first interface 102 is connected to the first charging loop 104, the second interface 103 is connected to the second charging loop 105, any charging interface and the charging loop connected thereto form a complete charging sub-circuit, and the processor 101 can switch the charging sub-circuit currently used for charging by controlling switches in the charging sub-circuits.
In fig. 1(b), a plurality of charging interfaces correspond to one charging loop, the first interface 102 and the second interface 103 are both connected to the charging loop 106, and the processor 101 can control any charging interface and the charging loop to form a complete charging sub-circuit by controlling the switch of each charging interface, so as to charge the battery 107.
It should be noted that the electronic device may include the circuit structure shown in fig. 1(a), or include the circuit structure shown in fig. 1(b), or include both the circuit structure shown in fig. 1(a) and the circuit structure shown in fig. 1(b), and this embodiment is not limited in any way.
In addition, it should be noted that the electronic device may be connected to a power supply through a charging interface, and the power supply may include a power adapter or a portable power source, so that the power adapter or the portable power source is a device that charges a battery disposed in the device, and the electronic device may specifically be a mobile terminal or a portable power source, and the embodiment is not limited in any way herein.
As shown in fig. 2, which is a flowchart illustrating steps of the charging method according to an embodiment of the present invention, the method may include the following steps:
step 201: the processor determines a first input power of the first interface and a second input power of the second interface.
In an implementation manner of this embodiment, the determining, by the processor, the input power of any charging interface may specifically include:
the processor detects the voltage value and the charging current value of the battery of the electronic equipment, and determines the input power of any charging interface according to the voltage value and the charging current value of the battery. For example, the step of determining the first input power may specifically comprise:
the processor determining a voltage value of the battery;
the processor determines a current value corresponding to the first interface (a current value flowing through the battery through the first interface); and
the processor determines the first input power according to a voltage value and a current value of the battery.
Further, before the processor detects a voltage value and a charging current value of a battery of the electronic device, the method may further include: the processor determines that the power supply connected with any charging interface is charging the electronic equipment currently.
That is, for a power supply that is charging a battery of an electronic device, if a loss in a charging loop is ignored, the input power of a charging interface to which the power supply is connected, that is, the output power of the power supply, can be approximately determined by detecting a voltage value and a charging current value of the battery of the electronic device. In addition, it should be noted that the input power of any charging interface may also be determined by detecting the input voltage value and the input current value received at any charging interface.
It should be noted that the voltage value and the current value may be detected by a specially provided sampling circuit, or may be detected by an electricity meter provided in a battery module of the electronic device, and the embodiment is not limited in any way herein.
In another implementation manner of this embodiment, the determining, by the processor, the input power of any charging interface may further include:
and the processor is communicated with the power supply connected with any charging interface to acquire power information of the power supply.
For example, the step of determining the first input power may specifically comprise:
the processor communicates with a power supply connected to the first interface to obtain power information to determine the first input power.
It should be noted that the power information of the power supply includes, but is not limited to, an output voltage value range, an output current value range, model identification information of the power supply, and/or supportable charging mode information. That is, for a power supply that charges a battery of an electronic device or a power supply that is connected to the electronic device only and does not charge the battery, the power supply may communicate with the power supply based on a set communication protocol to obtain information that can be used to represent a rated power value of the power supply, such as an output voltage range, an output current range, model information of the power supply, and/or supportable charging mode information of the power supply.
In addition, optionally, the processor may further control a set identification chip to communicate with the power supply, and the set identification chip determines the input power of any one of the charging interfaces according to the acquired power information of the power supply.
In an implementation manner of this embodiment, before the processor determines the first input power of the first interface and the second input power of the second interface in step 201, the method may further include:
the processor determines that the first interface is connected to a first power source and the second interface is connected to a second power source.
That is, when multiple power sources are connected to the electronic device through multiple charging interfaces, the charging method provided by the embodiment may be triggered.
Optionally, for any charging interface, the any charging interface may specifically be a wired charging interface or a wireless charging interface, and specifically, the any charging interface may include, but is not limited to, a USB 2.0 interface, a type-C interface, or a receiving coil. The present embodiment is not limited thereto.
Further optionally, the determining, by the processor, that any charging interface is connected to the power supply may specifically include:
the processor determines that any charging interface is connected with the power supply through a communication cable; or the like, or, alternatively,
the processor determines that any charging interface is connected with the power supply coupling.
For example, the processor determines that the first interface is connected or coupled to a first power source via a communication cable; and determining that the second interface is connected or coupled with a second power source through a communication cable.
That is, since the USB 2.0 interface or the type-C interface and other wired charging interfaces are electrically connected to the power supply through the charging cable; the wireless charging interfaces such as the receiving coil and the like are coupled with the power supply based on the principles such as electromagnetic induction, magnetic resonance, electric field coupling or radio wave transmission, so that for any charging interface, if the charging interface is determined to be electrically connected or coupled with the power supply, the charging interface can be determined to be connected with the power supply.
In addition, it should be noted that the specific method for determining whether any charging interface is electrically connected to the power supply and determining whether any charging interface is coupled to the power supply is similar to the prior art, and this embodiment is not described herein again.
Step 202: the processor determines that the first input power is greater than the second input power and selects to charge the battery through the first interface.
That is, the processor may determine the output power of each power source connected to the electronic device, respectively, from which the power source having the larger output power is determined to charge the electronic device. After determining that the electronic device is charged through the first interface, the processor may first control the switch corresponding to the first interface to be turned on, and the switches corresponding to the other charging interfaces are all turned off; then, the first interface is communicated with a power supply connected with the first interface, the power supply is controlled to output proper voltage and current to charge a battery of the electronic device, the charging process of the battery is similar to that of the prior art, and details are not repeated here in this embodiment.
In an implementation manner of this embodiment, the method may further include:
step 202': if the processor determines that the first input power is equal to the second input power; the processor determines a first current value of the first interface and determines a second current value of the second interface; the processor determines that the first current value is greater than the second current value and selects to charge the battery through the first interface. The first charging current value is the amplitude of current flowing through a battery of the electronic equipment when the electronic equipment is charged through the first interface; the second charging current value is an amplitude of a current flowing through a battery of the electronic device when the electronic device is charged through the second interface.
That is, when the output powers of the power supplies connected to the electronic device are the same, the processor selects a power supply having a large charging current to charge the electronic device.
In an implementation manner of this embodiment, the method may further include:
step 202 ": if the processor determines that the first input power is equal to the second input power and the first charging current value is equal to the second charging current value, the processor selects a charging interface which is connected with the power supply firstly to charge the electronic equipment; the first charging current value is the amplitude of current flowing through a battery of the electronic equipment when the electronic equipment is charged through the first interface; the second charging current value is an amplitude of a current flowing through a battery of the electronic device when the electronic device is charged through the second interface.
That is, when the output power and the charging current of each power supply connected to the electronic device are the same, the processor selects the power supply that is first connected to the electronic device to charge the electronic device.
Alternatively, the processor may be a set controller; for example, if the electronic device is a mobile terminal, the processor may specifically be an application processor in the mobile terminal, or may be an MCU (micro controller Unit, single-chip microcomputer) specially used for charge control and arranged in the mobile terminal; for another example, if the electronic device is a mobile power supply, the processor may be an MCU in the mobile power supply, and this embodiment is not described herein again.
The charging method provided by the present embodiment will be described in detail below by taking a specific example as an example.
Example one:
assuming that the mobile power supply is provided with an interface 1 and an interface 2, as shown in fig. 3, the charging control process is as follows:
step 301: starting;
step 302: detecting the insertion of the adapter;

step 305: judging whether the interface 2 is charging, if not, skipping to the step 302; if yes, go to step 314;
step 306: judging whether the interface 2 is connected with an adapter, if so, jumping to step 307; if not, jumping to step 308;
step 307: judging whether the interface 2 is charging, if not, skipping to the step 308; if yes, go to step 312;
step 308: keeping the interface 1 for charging until the charging is finished, and jumping to step 315, or detecting that an adapter is inserted again;
step 309: judging whether the interface 2 is connected with an adapter, if so, jumping to a step 310; if not, jumping to step 302;
step 310: judging whether the interface 2 is charging, if not, skipping to the step 302; if yes, go to step 311;
step 311: judging whether the interface 1 is charging, if so, jumping to step 312; if not, jumping to step 314;
step 312: performing quick charge identification, determining first input power of the interface 1 and second input power of the interface 2, and determining the magnitude relation between the first input power and the second input power;
step 313: selecting an interface with larger input power for charging, and skipping to step 315 until the charging is finished, or detecting that an adapter is inserted again;
step 314: keeping the interface 2 to charge until the charging is finished, and jumping to step 315, or detecting that an adapter is inserted again;
step 315: and (6) ending.
Example two:
suppose that the mobile power supply is provided with a micro USB interface and a type-C interface, and the power adapter A charges the mobile power supply through the micro USB interface. At a certain moment, the user accesses the power adapter B to the type-C interface of the mobile power supply, and then the charging control process is as follows:
step A: the MCU of the mobile power supply determines that a type-C interface is connected with the power adapter B, and a micro USB interface is connected with the power adapter A;
and B: the MCU acquires a charging voltage value and a charging current value of the battery based on the set sampling circuit, and estimates the output power of the power adapter A to be P1 according to the acquired charging voltage value and charging current value;
and C: the MCU is communicated with the power adapter B based on a set communication protocol, and the rated power of the power adapter B is determined to be P2;
step D: if the MCU determines that the P1 is greater than or equal to P2, executing a step E; if it is determined that P1 is less than P2, perform step F;
step E: the MCU controls a switch K1 corresponding to the micro USB interface to be closed and a switch K2 corresponding to the type-C interface to be switched off, and the power adapter A is continuously controlled to charge the battery;
step F: the MCU controls the switch K1 corresponding to the micro USB interface to be switched off, and the switch K2 corresponding to the type-C interface to be switched on, so that the power adapter B is controlled to charge the battery.
