Description

Charging method, device, power adapter and storage medium

Technical Field

The present disclosure relates to the field of charging technologies, and in particular, to a charging method, a device, a power adapter, and a storage medium.

Background

Electronic devices such as cell phones, tablet computers, etc. typically require charging by a charger. The charger typically includes a power adapter and a power transmission line. The power adapter can convert alternating-current commercial power into direct-current power, and output the direct-current power from a port of the power adapter after voltage conversion. The power transmission line is connected between the port of the power adapter and the electronic equipment to transmit the direct current output by the port of the power adapter to the electronic equipment to charge the electronic equipment.

The power adapter may have a plurality of ports, each of which may be connected to one electronic device through one power transmission line, so that the power adapter may charge the plurality of electronic devices through its own plurality of ports one by one. Currently, in the case where a power adapter charges a plurality of electronic devices at the same time, the maximum output power of each of a plurality of ports of the power adapter is fixed throughout the charging process.

For example, the maximum output power of the power adapter itself is 100W (watts), and the power adapter has three ports. If the power adapter charges three electronic devices through the three ports, the power adapter may assign a maximum output power of 50W to the first port by default, assign a maximum output power of 20W to the second port by default, and assign a maximum output power of 30W to the third port by default.

However, such a manner of fixedly distributing the maximum output power to the respective ports of the power adapter during the charging is low in flexibility, and it is difficult to exert the maximum charging capability of the power adapter, resulting in low charging efficiency.

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

It should be understood that reference herein to "a plurality" means two or more. In the description of the present application, "/" means or, unless otherwise indicated, for example, a/B may represent a or B; "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. In addition, for the purpose of facilitating the clear description of the technical solutions of the present application, the words "first", "second", etc. are used to distinguish between the same item or similar items having substantially the same function and effect. It will be appreciated by those of skill in the art that the words "first," "second," and the like do not limit the amount and order of execution, and that the words "first," "second," and the like do not necessarily differ.

The statements of "one embodiment" or "some embodiments" and the like, described in this application, mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," and the like in various places throughout this application are not necessarily all referring to the same embodiment, but mean "one or more, but not all, embodiments" unless expressly specified otherwise. Furthermore, the terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically noted.

Before explaining the charging method provided in the embodiment of the present application in detail, an application scenario of the embodiment of the present application is described first.

Electronic devices such as cell phones, tablet computers, notebook computers, wearable devices, etc. typically require charging by a charger. The charger typically includes a power adapter and a power transmission line. The power adapter can convert alternating-current commercial power into direct-current power, and output the direct-current power from a port of the power adapter after voltage conversion. The power transmission line is connected between the port of the power adapter and the electronic equipment to transmit the direct current output by the port of the power adapter to the electronic equipment to charge the electronic equipment.

Currently, as shown in fig. 1, the power adapter 100 may have a plurality of ports 101, each port 101 of the plurality of ports 101 of the power adapter 100 being configured to output direct current. In some embodiments, the power adapter 100 having multiple ports 101 may be referred to as a multi-port adapter, also referred to as a multi-port charger.

As shown in fig. 2, any one port 101 among the plurality of ports 101 of the power adapter 100 may be connected to one electronic device 103 through one power transmission line 102. In this manner, the power adapter 100 may charge the plurality of electronic devices 103 one by one through its plurality of ports 101, and this charging process may be referred to as a multiple charging process.

In the related art, in the case where the power adapter 100 charges a plurality of electronic devices at the same time, the maximum output power of each of the plurality of ports 101 of the power adapter 100 is fixed throughout the charging process, that is, the maximum output power of each of the ports 101 cannot be adjusted during the charging process, resulting in lower charging flexibility, difficulty in exerting the maximum charging capability of the power adapter 100, and thus lower charging efficiency.

Therefore, the embodiment of the application provides a charging method, which can safely and reasonably adjust the maximum output power of each port according to the first charging information of the power adapter and the second charging information of the electronic equipment connected with each port of the power adapter. Therefore, the charging flexibility is improved, the charging capability of the power adapter can be exerted to the greatest extent under the condition that the charging requirement of the electronic equipment is met, and the charging efficiency can be improved.

Computer devices provided in embodiments of the present application are described below.

Fig. 3 is a schematic structural diagram of a computer device according to an embodiment of the present application, and the computer device may be the power adapter 100 shown in fig. 1 or fig. 2. Referring to fig. 3, the computer device includes a processor 301, a communication bus 302, a memory 303, and a plurality of ports 304.

The processor 301 may be a microprocessor (including a central processing unit (central processing unit, CPU), etc.), an application-specific integrated circuit (ASIC), or may be one or more integrated circuits for controlling the execution of programs in accordance with aspects of the present application.

As one example, the processor 301 may include one or more CPUs.

As one example, the computer device may include a plurality of processors 301. Each of these processors 301 may be a single-core processor or may be a multi-core processor. A processor herein may refer to one or more devices, circuits, and/or processing cores for processing data (e.g., computer program instructions).

Communication bus 302 may include a path for transferring information between the above components.

The memory 303 may be, but is not limited to, read-Only memory (ROM), random-access memory (random access memory, RAM), electrically erasable programmable read-Only memory (EEPROM), optical disks (including, but not limited to, compact discs (compact disc read-Only memory, CD-ROM), compact discs, laser discs, digital versatile discs, blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer. The memory 303 may be stand alone and be coupled to the processor 301 via the communication bus 302. Memory 303 may also be integrated with processor 301.

Any one port 304 of the plurality of ports 304 may be coupled to an electronic device via a power transmission line. Each port 304 of the plurality of ports 304 is configured to output direct current to charge a connected electronic device. And, each port 304 of the plurality of ports 304 is also configured to communicate with a connected electronic device.

Wherein the memory 303 is used for storing program code 310 for executing the present application, and the processor 301 is used for executing the program code 310 stored in the memory 303. The computer device may implement the charging method provided by the embodiment of fig. 4 below by means of a processor 301 and program code 310 in a memory 303.

Fig. 4 is a flowchart of a charging method according to an embodiment of the present application, where the method is applied to a power adapter, which may be a computer device as described above in the embodiment of fig. 3. Referring to fig. 4, the method includes:

step 401: under the condition that n ports in the multiple ports of the power adapter are connected with n electronic devices one by one, the first charging information of the power adapter is obtained, the second charging information of each electronic device in the n electronic devices is obtained, and n is a positive integer.

The power adapter in the embodiment of the present application is a multi-port adapter, that is, the power adapter has a plurality of ports, where each port of the plurality of ports may be connected to one electronic device, for example, each port may be connected to one electronic device through one power transmission line. The power adapter can convert alternating-current commercial power into direct-current power, and output the direct-current power from a port of the power adapter after voltage conversion. That is, each of the plurality of ports is configured to output direct current to charge the connected electronic device.

In this way, in the case where n ports among the plurality of ports of the power adapter are connected to n electronic devices one by one, the power adapter can charge the connected electronic devices through each of the n ports. When n is equal to 1, one port of the power adapter is connected with one electronic device, and the power adapter charges one electronic device, namely, charges one way. And when n is greater than or equal to 2, at least two ports in the power adapter are connected with at least two electronic devices one by one, and at the moment, the power adapter charges at least two electronic devices at the same time, namely, multipath charging is realized. For example, as shown in fig. 2, the power adapter 100 has three ports 101, and two ports 101 of the three ports 101 are connected to two electronic devices 103 one by one, in which case the power adapter 100 charges the two electronic devices 103 at the same time.

It should be noted that, in the embodiment of the present application, the power adapter may preset an initial maximum output power for each of its multiple ports, where the initial maximum output power is allocated to each port by default by the power adapter in advance. The initial maximum output power of each of the plurality of ports may be the same or different, which is not limited in the embodiments of the present application.

In this case, when the power adapter detects that any one of the ports is connected to the electronic device, the maximum output power of the port may be set to be the initial maximum output power, and then the power adapter may dynamically adjust the maximum output power of the port during the process of charging the electronic device connected to the port through the port.

The power adapter can charge the electronic device connected with the port according to the maximum output power of the port, that is, the power adapter can adjust the actual output power of the port in the process of charging the electronic device connected with the port through the port, and the actual output power of the port needs to be ensured not to be larger than the maximum output power of the port all the time in the process of adjusting the actual output power of the port.

The power adapter has a maximum output power, and a sum of the maximum output powers of each of the plurality of ports of the power adapter is less than or equal to the maximum output power of the power adapter. That is, the sum of the initial maximum output powers of the individual ports of the plurality of ports needs to be less than or equal to the maximum output power of the power adapter. In addition, when the power adapter dynamically adjusts the maximum output power of each port in the process of charging the connected electronic equipment through each port in the plurality of ports, the sum of the adjusted maximum output power of each port is required to be smaller than or equal to the maximum output power of the power adapter.

In some embodiments, when the power adapter detects that any one of the ports is connected to the electronic device, that is, when the power adapter detects that any one of the ports is switched from an unconnected state (i.e., a state of not being connected to the electronic device) to a connected state (i.e., a state of being connected to the electronic device), the power adapter may determine all ports of the ports that are currently in a connected state (i.e., all ports that are currently being connected to the electronic device), and uniformly set the maximum output power of each of the ports that are in a connected state to the initial maximum output power of each port. The power adapter may then dynamically adjust the maximum output power of each of the ports during charging of the connected electronic device through each of the ports in the connected state.

That is, in this embodiment of the present application, when any one of the plurality of ports of the power adapter is connected to the electronic device, the power adapter resets the maximum output power of all the ports currently connected to the electronic device, that is, resets the maximum output power of each port to the initial maximum output power, so that it can be ensured that all the ports currently connected to the electronic device can normally charge the electronic device. Without affecting the maximum output power of the port that is still currently connected to the electronic device when any one of the plurality of ports of the power adapter is disconnected from the electronic device. That is, when the power adapter detects that any one of the plurality of ports is disconnected from the electronic device, that is, when the power adapter detects that any one of the ports is switched from the connected state to the unconnected state, the power adapter can maintain the maximum output power of each port still in the connected state.

For example, the power adapter has three ports, namely, port 1, port 2 and port 3, and assuming that the maximum output power of the power adapter is 100W, the initial maximum output power of port 1 is 50W, the initial maximum output power of port 2 is 20W, and the initial maximum output power of port 3 is 30W. The user connects port 1 with the electronic device, when the power adapter detects that port 1 is connected with the electronic device, the maximum output power of port 1 currently connected with the electronic device is set to be the initial maximum output power 50W. Thereafter, the power adapter may dynamically adjust the maximum output power of port 1 during the process of charging the electronic device through port 1, assuming that the power adapter adjusts the maximum output power of port 1 from 50W to 30W. After that, the user connects the port 2 with the electronic device, when the power adapter detects that the port 2 is connected with the electronic device, the maximum output power of the port 1 and the maximum output power of the port 2 which are currently connected with the electronic device are set to be initial maximum output power, namely, the maximum output power of the port 1 is reset from 30W to be initial maximum output power 50W, and the maximum output power of the port 2 is set to be initial maximum output power 20W. Then, the power adapter can dynamically adjust the maximum output power of the port 1 and the port 2 in the process of charging the electronic device through the port 1 and the port 2, and the power adapter is supposed to adjust the maximum output power of the port 1 from 50W to 30W and adjust the maximum output power of the port 2 from 20W to 10W. Then, when the user connects the port 3 with the electronic device and the power adapter detects that the port 3 is connected with the electronic device, the maximum output power of the port 1, the maximum output power of the port 2 and the maximum output power of the port 3 which are currently connected with the electronic device are all set to be initial maximum output power, namely, the maximum output power of the port 1 is reset from 30W to be initial maximum output power 50W, the maximum output power of the port 2 is reset from 10W to be initial maximum output power 20W, and the maximum output power of the port 3 is set to be initial maximum output power 30W. Then, the power adapter can dynamically adjust the maximum output power of the port 1, the port 2 and the port 3 in the process of charging the electronic device through the port 1, the port 2 and the port 3, and the power adapter is supposed to adjust the maximum output power of the port 1 from 50W to 30W, the maximum output power of the port 2 from 20W to 10W and the maximum output power of the port 3 from 30W to 60W. Then, the user disconnects the port 1 from the electronic device, and at this time, the power adapter detects that the port 1 is disconnected from the electronic device, so that the maximum output power of the port 2 and the maximum output power of the port 3, which are still connected with the electronic device at present, can be maintained unchanged, that is, the maximum output power of the port 2 is maintained to be 10W at present, and the maximum output power of the port 3 is maintained to be 60W at present. In addition, the power adapter can continuously and dynamically adjust the maximum output power of the port 2 and the port 3 in the process of charging the electronic equipment through the port 2 and the port 3.

In this embodiment of the present application, the power adapter may dynamically adjust the maximum output power of each port connected to the electronic device according to the first charging information of the power adapter and the second charging information of the electronic device.

The first charging information of the power adapter is some information of the power adapter related to charging. For example, the first charging information of the power adapter may include at least one of: an output voltage of each of n ports connected to the electronic device; an output current of each of the n ports; the output power of each of the n ports; maximum output power for each of the n ports; the temperature of the power adapter; protection policy of the power adapter. Of course, the first charging information may include other charging-related information of the power adapter in addition to the above-listed information, which is not limited in the embodiment of the present application.

Optionally, the protection policy of the power adapter may include a maximum output current (i.e. an overcurrent point) and a maximum output voltage (i.e. an overvoltage point) corresponding to the maximum output power of each of the plurality of ports. The protection strategy of the power adapter may further include limiting output power, limiting output voltage and limiting output current of each of the plurality of ports, where the limiting output power, limiting output voltage and limiting output current of each port are physical endurance limits of each port, that is, the electronic device may be damaged after exceeding the limiting output power, limiting output voltage and limiting output current of each port.

When the power adapter charges the electronic equipment according to the maximum output power of a certain port, the output power of the port needs to be controlled to be not more than the maximum output power of the port, the output current of the port is controlled to be not more than the maximum output current corresponding to the maximum output power of the port, and the output voltage of the port is controlled to be not more than the maximum output voltage corresponding to the maximum output power of the port. In this way, it can be ensured that the output power of this port does not exceed the relevant requirements of the maximum output power of this port.

When the power adapter dynamically adjusts the maximum output power of a certain port, the adjusted maximum output power of the port needs to be controlled to be not more than the limit output power of the port, the maximum output current corresponding to the adjusted maximum output power of the port is controlled to be not more than the limit output current of the port, and the maximum output voltage corresponding to the adjusted maximum output power of the port is controlled to be not more than the limit output voltage of the port. Therefore, the power adapter can be ensured not to damage electronic devices when the electronic equipment is charged through the port, and the safe charging process is ensured.

It should be noted that, in the case that the n ports of the power adapter are connected to the n electronic devices one by one, the power adapter may acquire the first charging information of the power adapter at intervals of a preset time. That is, the power adapter may continuously obtain the first charging information of the power adapter in the process of charging the n electronic devices, and may dynamically adjust the maximum output power of each of the n ports according to the newly obtained first charging information.

The second charging information of the electronic device is some information of the electronic device related to charging. For example, the second charging information of a certain electronic device may include at least one of the following: a historical charging record of the electronic device; the charging protocol supported by this electronic device; a charging strategy for this electronic device; status information of this electronic device. Of course, the second charging information may include other charging-related information of the electronic device in addition to the above-listed information, which is not limited in the embodiment of the present application.

Optionally, when the power adapter charges a certain electronic device through a certain port, the power adapter may acquire a device identifier of the electronic device during a charging process of the electronic device, record charging information (which may be referred to as port charging information) such as output current, output voltage, output power and the like of the port, and after the charging of the electronic device is finished, that is, after the port is disconnected from the electronic device, the power adapter may store the device identifier of the electronic device in correspondence with related charging information recorded during the charging process of the electronic device, so as to obtain a historical charging record of the electronic device. The historical charging record of the electronic device comprises the device identification and port charging information of the electronic device, wherein the port charging information comprises output current, output voltage, output power and the like of a port for charging the electronic device in the whole charging process. The device identifier of the electronic device is used to uniquely identify the electronic device, for example, the device identifier of the electronic device may be a Serial Number (SN) of the electronic device, etc.

Optionally, the electronic device may support one or more charging protocols. The charging protocol may specify a maximum charging power that the electronic device can support, a corresponding charging current and charging voltage, and so on. For example, the electronic device may support a super charging protocol (super charge protocol, SCP), a Power Delivery (PD) charging protocol, and so on.

Optionally, one or more charging strategies may be included in the electronic device. The charging strategy is used to indicate the charging mode in certain scenarios. For example, the charging policy may indicate the manner in which the electronic device is charged when the temperature of the electronic device is too high, or the charging policy may indicate the manner in which the electronic device is charged when some particular application (e.g., a gaming application) is running. The charging mode may include, among others, the maximum allowed charging power, the referenced charging curve, etc. The charging curve is a graph of a charging current versus a charging voltage, and may include a plurality of charging phases, for example, a trickle charging phase, a constant current charging phase, a constant voltage charging phase, and a cut-off charging phase. The electronic device may instruct the power adapter to charge itself according to the charging mode.

Alternatively, the status information of the electronic device may include information of a temperature, an electric quantity, and the like of the electronic device. Of course, the state information of the electronic device may further include other information, for example, may include a battery capacity of the electronic device, a remaining capacity percentage of the electronic device, and the like, and may further include an application scenario of the electronic device, a current and a voltage of the battery, and the like, which is not limited in the embodiment of the present application.

In some embodiments, when the power adapter establishes a connection with an electronic device at any one of the ports, the power adapter may acquire a device identifier of the electronic device, for example, the power adapter may send a first request message to the electronic device through the port, where the first request message is used to request to acquire the device identifier of the electronic device, and after receiving the first request message sent by the power adapter, the electronic device may send its device identifier to the power adapter. After the power adapter acquires the equipment identifier of the electronic equipment, whether the historical charging record of the electronic equipment exists or not can be searched from all the historical charging records stored by the power adapter according to the equipment identifier of the electronic equipment, namely whether the historical charging record containing the equipment identifier of the electronic equipment exists or not is searched from all the historical charging records stored by the power adapter, and specifically, if a certain stored historical charging record contains the equipment identifier of the electronic equipment, the historical charging record is determined to be the historical charging record of the electronic equipment; if all the stored historical charging records do not contain the equipment identification of the electronic equipment, determining that the historical charging records of the electronic equipment are not stored in the power adapter.

If the power adapter finds the historical charging record of the electronic device, the power adapter can determine the historical charging record of the electronic device as second charging information. Optionally, in this case, the power adapter does not need to acquire other charging information of the electronic device, for example, does not need to acquire a charging protocol supported by the electronic device, a charging policy of the electronic device, status information of the electronic device, and the like. The adjustment of the maximum output power of the port to which the electronic device is connected can be achieved subsequently based on the historical charging record of the electronic device. Thus, the processing resource of the power adapter can be saved, and the processing pressure of the power adapter can be reduced.

If the power adapter does not find the historical charging record of the electronic device, the power adapter may acquire related charging information from the electronic device as second charging information at intervals of a preset time interval in the charging process of the electronic device, for example, may acquire charging information such as charging protocols supported by the electronic device, charging strategies of the electronic device, state information of the electronic device and the like at intervals of a preset time interval as second charging information. That is, the power adapter may continuously acquire the second charging information from the electronic device during the charging process of the electronic device, and may dynamically adjust the maximum output power of the port connected to the electronic device from the n ports according to the newly acquired second charging information of the electronic device.

For example, when the power adapter obtains the relevant charging information from the electronic device, the power adapter may send a second request message to the electronic device through a port to which the electronic device is connected, where the second request message is used to request to obtain the charging information of the electronic device. After receiving the second request message sent by the power adapter, the electronic device can send its charging information to the power adapter. After the power adapter receives the charging information sent by the electronic device, the received charging information can be used as second charging information of the electronic device.

In some embodiments, this electronic device may also actively send its own charging information to the power adapter. For example, the electronic device may acquire its own charging information at regular intervals during the charging process, and send its own charging information to the power adapter. And/or the electronic device may send its own charging information to the power adapter in some special scenarios during the charging process, for example, the electronic device may send its own charging information to the power adapter when its own temperature is too high, or send its own charging information to the power adapter when its own runs some specific applications.

Step 402: for any one of the n ports, the power adapter adjusts the maximum output power of the one port according to the first charging information of the power adapter and the second charging information of the electronic device to which the one port is connected.

The first charging information of the power adapter can embody the charging capability of the power adapter, and the second charging information of the electronic equipment can embody the charging requirement of the electronic equipment, so that the maximum output power of each port can be safely and reasonably adjusted according to the first charging information of the power adapter and the second charging information of the electronic equipment connected with each port. Therefore, the charging flexibility is improved, the charging capability of the power adapter can be exerted to the greatest extent under the condition that the charging requirement of the electronic equipment is met, and the charging efficiency can be improved.

Notably, the power adapter has idle power. The idle power is the power that the power adapter has not yet allocated to a port. That is, the idle power is obtained by subtracting the sum of the maximum output power of the power adapter and the maximum output power of each of all ports connected to the electronic device in the power adapter. The idle power may be allocated by the power adapter for ports at a later appropriate time. For example, the maximum output power of the power adapter is 100W, and the power adapter has three ports, which are respectively: port 1, port 2, port 3, wherein port 1 is not connected with the electronic device, port 2 and port 3 are both connected with the electronic device, and the maximum output power of port 2 is 20W, and the maximum output power of port 3 is 70W, then the idle power of the power adapter is 100W-20W-70 w=10w.

In the embodiment of the application, when the maximum output power of each port is dynamically adjusted, the power adapter can synchronously update the idle power. For example, the power adapter may update the idle power after reducing the maximum output power of one port, for example, the idle power of the power adapter is 10W, and the idle power of the power adapter is updated to 10w+5w=15w after the power adapter reduces the maximum output power of one port by 5W. For example, the power adapter may update the idle power after increasing the maximum output power of one port, for example, the idle power of the power adapter is 10W, and the idle power of the power adapter is updated to 10W-5 w=5W after the power adapter increases the maximum output power of one port by 5W.

Optionally, in a case where the second charging information of the electronic device to which the one port is connected is charging information obtained by the power adapter from the electronic device, that is, in a case where the second charging information of the electronic device is not a historical charging record of the electronic device, the operation of the power adapter to adjust the maximum output power of the one port according to the first charging information of the power adapter and the second charging information of the electronic device to which the one port is connected may be implemented in the following first manner. In the case where the second charging information of the electronic device to which the one port is connected is the history charging record of the electronic device, the operation of the power adapter to adjust the maximum output power of the one port according to the first charging information of the power adapter and the second charging information of the electronic device to which the one port is connected may be achieved in the following second manner.

The first way is: if the first charging information of the power adapter and/or the second charging information of the electronic equipment connected with the one port meet the power reduction condition, the maximum output power of the one port is reduced; and if the first charging information of the power adapter and the second charging information of the electronic device connected with the one port meet the power increasing condition, increasing the maximum output power of the one port.

One or more power reduction conditions can be preset in the power adapter, the power reduction conditions can be set by technicians according to actual requirements, and the power reduction conditions can be set on the premise of safely and reasonably distributing power. The power reduction condition is used to indicate that the maximum output power of the port is reduced if the first charging information and/or the second charging information satisfies the power reduction condition. For example, the power reduction condition may be: the output power of a port is less than 0.5 times the maximum output power of the port, or the power reduction condition may be: the temperature of the electronic device to which the port is connected is greater than a temperature threshold, which may be set in advance. Of course, the power reduction condition may be other conditions as long as the maximum output power of the port can be reduced under a safe and reasonable charging condition.

In some embodiments, if the first charging information of the power adapter and/or the second charging information of the electronic device to which the one port is connected satisfy the power reduction condition, the power adapter may first send a power reduction request message to the electronic device through the one port, where the power reduction request message is used to request to reduce the maximum output power of the one port. If the electronic device determines that the maximum output power of the one port can be reduced after receiving the power reduction request message sent by the power adapter, sending an agreement message to the power adapter, and reducing the maximum output power of the one port after receiving the agreement message. If the electronic device receives the power reduction request message sent by the power adapter, and determines that the maximum output power of the one port cannot be reduced, a rejection message is sent to the power adapter, and the power adapter gives up reducing the maximum output power of the one port after receiving the rejection message, namely, maintains the current maximum output power of the one port.

When the maximum output power of the one port is reduced, the power adapter may reduce the maximum output power of the one port by a preset power, where the preset power may be preset, for example, the preset power may be 5W. Alternatively, when the maximum output power of the one port is reduced, the maximum output power of the one port may be reduced according to a preset ratio, and the preset ratio may be preset, for example, the preset ratio may be 20%, that is, the maximum output power of the one port may be reduced by 20%.

One or more power increasing conditions can be preset in the power adapter, the power increasing conditions can be set by technicians according to actual demands, and the power increasing conditions can be set on the premise of safely and reasonably distributing power. The power increase condition is used to indicate that the maximum output power of the port is increased if the first charging information and/or the second charging information satisfies the power increase condition. For example, the power increase condition may be: the output power of a port is less than 0.5 times the maximum charging power in the charging protocol currently used by the electronic device to which the port is connected. Of course, the power increasing condition may be other conditions as long as the maximum output power of the port can be increased under a safe and reasonable charging condition.

In some embodiments, if the first charging information of the power adapter and/or the second charging information of the electronic device to which the one port is connected satisfy the power increase condition, determining a target power to be increased; if the target power is greater than the idle power of the power adapter, increasing the maximum output power of the one port by the idle power; if the target power is less than or equal to the idle power of the power adapter, the maximum output power of the one port is increased by the target power.

Optionally, if the first charging information of the power adapter and/or the second charging information of the electronic device connected to the one port satisfy the power increasing condition, searching whether the idle power of the power adapter is 0. If the idle power is 0, the power adapter discards increasing the maximum output power of the one port, i.e., maintaining the current maximum output power of the one port. If the idle power is not 0, the power adapter sends a power increase request message to the electronic device through the one port, wherein the power increase request message is used for requesting to increase the maximum output power of the one port; if the electronic device receives the power increase request message sent by the power adapter, determining that the maximum output power of the one port can be increased, determining that the target power needs to be increased, carrying the target power in an agreement message, and sending the agreement message to the power adapter, wherein the power adapter can increase the maximum output power of the one port according to the target power after receiving the agreement message sent by the electronic device, and can specifically select a smaller one of the target power and idle power as an increase value of the maximum output power of the one port; and if the electronic equipment receives the power increase request message sent by the power adapter and determines that the maximum output power of the one port cannot be increased, a rejection message is sent to the power adapter, and the power adapter gives up increasing the maximum output power of the one port after receiving the rejection message sent by the electronic equipment, namely, the current maximum output power of the one port is maintained.

In some embodiments, the power adapter may not only adjust the maximum output power of the one port according to the first charging information of the power adapter and the second charging information of the electronic device to which the one port is connected, but may also adjust the charging protocol of the electronic device.

Optionally, if the first charging information of the power adapter and/or the second charging information of the electronic device connected to the one port meet the charging protocol switching condition, the power adapter may further switch a charging protocol used by the electronic device.

The charging protocol switching condition may be set in advance. The charging protocol switching condition can be set by a technician according to actual requirements. The charging protocol switching condition is used for indicating to switch the charging protocol used by the electronic device when the first charging information and/or the second charging information meet the charging protocol switching condition. For example, the charging protocol switching condition may be: the sum of the maximum output power and the idle power of the port is larger than the maximum charging power in the charging protocol currently used by the electronic equipment connected with the port and smaller than or equal to the maximum charging power in another charging protocol supported by the electronic equipment. Of course, the charging protocol switching condition may be other conditions, as long as the charging protocol used by the electronic device can be switched under the safe and reasonable charging condition.

If the first charging information of the power adapter and/or the second charging information of the electronic device connected to the one port meet the charging protocol switching condition, the power adapter may send a charging protocol switching request message to the electronic device, where the charging protocol switching request message may carry a charging protocol identifier (including, but not limited to, a name of a charging protocol), and the charging protocol switching request message is used to request to switch to the charging protocol identified by the charging protocol identifier. After the electronic equipment receives the charging protocol switching request message, if the charging protocol can be switched, switching the charging protocol used by the electronic equipment to the charging protocol identified by the charging protocol identification, and sending an agreement message to the power adapter so as to inform the power adapter that the switching of the charging protocol is completed; if the charging protocol cannot be switched, the charging protocol used by the power adapter is not switched, and a rejection message is sent to the power adapter so as to inform the power adapter that the charging protocol is not switched currently.

The second way is: the power adapter determines a historical charging power curve of the electronic equipment according to second charging information of the electronic equipment connected with the port; the maximum output power of the one port is adjusted according to the first charging information of the power adapter and the historical charging power curve.

The historical charging record of the electronic equipment comprises port charging information, wherein the port charging information comprises output voltage, output current, output power and the like of a port connected with the electronic equipment in the previous charging process of the electronic equipment, so that the historical charging power curve of the electronic equipment can be determined according to the historical charging record of the electronic equipment. The historical charging power curve of the electronic device can reflect the change condition of the charging power of the electronic device in the previous charging process.

In this case, the power adapter can perform real-time intelligent tracking adjustment on the maximum output power of the port according to the historical charging power curve. That is, the power adapter may adjust the maximum output power of the one port to be close to the charging power in the historical charging power curve during charging of the electronic device based on the first charging information of the power adapter without exceeding the charging capability of the power adapter.

For example, the historical charging power curve of the electronic device indicates that the charging power gradually increases from 0W to 5W in the first 5 minutes after the electronic device starts to charge, and the charging power gradually increases from 5W to 15W in the next 5 minutes, the power adapter may adjust the maximum output power of the one port to 5W in the next 5 minutes if it is determined that the maximum output power of the one port is allowed to be adjusted to 5W based on the first charging information of the power adapter in the first 5 minutes after the one port is connected to the electronic device, and then the power adapter may adjust the maximum output power of the one port to 15W in the next 5 minutes if it is determined that the maximum output power of the one port is allowed to be adjusted to 15W based on the first charging information of the power adapter in the next 5 minutes.

Step 403: the power adapter charges the connected electronic device according to the maximum output power of each of the n ports.

For any one of the n ports, the power adapter may control the output power of the one port to be less than or equal to the maximum output power of the one port during charging of the connected electronic device through the one port.

Optionally, the power adapter may further obtain a device identifier of the connected electronic device during charging the connected electronic device according to the maximum output power of any one of the ports, and record charging information (which may be referred to as port charging information) such as output current, output voltage, output power, and the like of the one port. After the electronic device is charged, that is, after the one port is disconnected from the electronic device, the power adapter may store the device identifier of the electronic device in correspondence with the relevant charging information recorded in the charging process of the electronic device, so as to obtain a historical charging record of the electronic device. If the history of the electronic device is previously stored in the power adapter, the power adapter may replace the previously stored history of the electronic device with the latest obtained history of the electronic device. If the historical charging record of the electronic device is not stored in the power adapter before, the power adapter can directly store the obtained historical charging record of the electronic device.

In the embodiment of the application, under the condition that n ports in a plurality of ports of a power adapter are connected with n electronic devices one by one, first charging information of the power adapter is obtained, and second charging information of each electronic device in the n electronic devices is obtained. The first charging information of the power adapter can embody the charging capability of the power adapter, and the second charging information of the electronic equipment can embody the charging requirement of the electronic equipment, so that the maximum output power of each port in n ports can be safely and reasonably adjusted according to the first charging information of the power adapter and the second charging information of each electronic equipment in n electronic equipment, and the power adapter can charge the connected electronic equipment according to the maximum output power of each port in n ports. Therefore, the charging flexibility is improved, and the charging capability of the power adapter can be exerted to the greatest extent under the condition that the charging requirement of the electronic equipment is met, so that the charging efficiency can be improved.

For ease of understanding, the charging method described above in connection with the embodiment of fig. 4 is exemplarily described below with reference to fig. 5 and 6.

As an example, as shown in fig. 5, after one port in the power adapter is connected to the electronic device, the power adapter obtains the device identifier of the electronic device, and then searches the historical charging record of the electronic device from all the historical charging records stored in the power adapter according to the device identifier of the electronic device. If the power adapter searches the historical charging record of the electronic equipment, the maximum output power of the port is intelligently tracked and adjusted in real time according to the historical charging record of the electronic equipment, and the idle power of the power adapter is continuously updated in the process of adjusting the maximum output power of the port. In addition, the power adapter continuously stores charging information such as output current, output voltage, output power and the like of the port in the process of charging the electronic equipment through the port.

After the electronic device is charged, that is, after the port is disconnected from the electronic device, the power adapter may store the device identifier of the electronic device in correspondence with the relevant charging information recorded during the charging process of the electronic device, so as to obtain a historical charging record of the electronic device, and replace the historical charging record of the electronic device stored before with the latest obtained historical charging record of the electronic device.

As another example, as shown in fig. 6, the power adapter has three ports, respectively: port 1, port 2, port 3. The port 1 is connected with the electronic device 1, the power adapter charges the electronic device 1 through the port 1, the port 2 is connected with the electronic device 2, the power adapter charges the electronic device 2 through the port 2, the port 3 is connected with the electronic device 3, and the power adapter charges the electronic device 3 through the port 3.

The maximum output power of the power adapter is 100W, the initial maximum output power allocated by the power adapter to the port 1 is 50W, the initial maximum output power allocated by the power adapter to the port 2 is 30W, and the initial maximum output power allocated by the power adapter to the port 3 is 20W. Then, in the process of charging the three electronic devices, the power adapter adjusts the maximum output power of each port by using the charging method described in the embodiment of fig. 4, and under the conditions that the electronic device 1 is full, the percentage of the remaining power of the electronic device 2 is 80%, and the percentage of the remaining power of the electronic device 3 is 30%, the power adapter can dynamically adjust the maximum output power of the port 1 to 0W, dynamically adjust the maximum output power of the port 2 to 20W, and dynamically adjust the maximum output power of the port 3 to 70W. The power adapter has an idle power of 10W.
