Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application.

Currently, in order to enable electronic devices to realize fast charging, manufacturers generally configure their own dedicated fast charging protocols in the electronic devices. In practical applications, when a user desires to perform fast charging on an electronic device, at this time, the electronic device and another power supply device (e.g., a charger) are required to support the same fast charging protocol, at this time, power can be supplied to the electronic device through the another power supply device, so that the electronic device can be fast charged. As shown in fig. 1, fig. 1 is a schematic view of an application scenario provided by the present application. The electronic device 1 and the electronic device 2 are included in the figure, and the electronic device 1 and the electronic device 2 can be connected together through a transmission line, so that one of the two electronic devices can be charged to the other electronic device.

However, in the above usage scenario, when the user cannot obtain another power supply device matched with the fast charging protocol of the electronic device, at this time, the electronic device can only charge in a normal charging manner, which further causes the charging speed of the electronic device to be slow, and affects the usage experience of the user.

The application provides a charging method, a charging device, an electronic device and a storage medium, which are applied to electronic equipment and used for solving the technical problems.

The charging method, the charging device, the charging equipment and the storage medium applied to the electronic equipment are applied to a central processing unit in first electronic equipment, and in the method, a second protocol chip can support a plurality of second quick charging protocols. The central processing unit can determine the fast charging protocol to be matched from the plurality of fast charging protocols supported by the second protocol chip through the first identification result of the first protocol chip. Then, in the to-be-matched fast charging protocol, based on the power level of the to-be-matched fast charging protocol, the to-be-matched fast charging protocol may be sequentially identified, so as to determine the charging protocol that can be supported by the second electronic device.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 2 is a schematic flowchart of a charging method applied to an electronic device according to an embodiment of the present disclosure, and as shown in fig. 2, the method includes the following steps:

s201, responding to a trigger instruction, and acquiring a first identification result of a first protocol chip; the trigger instruction is used for indicating to charge the first electronic device, the first protocol chip supports the first fast charging protocol, and the first identification result represents whether the second electronic device connected with the first electronic device supports the first fast charging protocol.

For example, the method provided in this embodiment is applied to a central processing unit of a first electronic device, where the first electronic device includes the central processing unit, a first protocol chip, and at least one second protocol chip, and the second protocol chip in this embodiment may support a plurality of second fast charging protocols, the first protocol chip supports a first fast charging protocol, and the first fast charging protocol is different from each of the second fast charging protocols.

When the central processing unit in the first electronic device determines that the second electronic device is to charge the first electronic device based on the trigger instruction, the central processing unit may receive a first identification result determined by the first protocol chip in the first electronic device, where the first identification result may be used to indicate whether the second electronic device charging the first electronic device supports the first fast charging protocol supported by the first protocol chip.

In an example, the first protocol chip may be configured to detect whether a second electronic device for charging the first electronic device is inserted into a charging port of the first electronic device, and when it is determined that the second electronic device exists, the first protocol chip may send a trigger instruction to the central processing unit, so that the central processing unit receives a first identification result of the first protocol chip.

In one example, the central processor may detect whether a second electronic device for charging the first electronic device is plugged into a charging port of the first electronic device.

In an example, when the first protocol chip determines the first identification result, the first protocol chip may perform protocol identification with the second electronic device to determine the first identification result, where a protocol identification process may refer to a protocol identification technology in the related art, and details are not described here.

S202, determining at least one fast charging protocol to be matched from a plurality of second fast charging protocols supported by a second protocol chip according to the first identification result; the first fast charge protocol is different from each of the second fast charge protocols.

For example, in this embodiment, after the central processing unit obtains the first identification result, at least one fast charging protocol to be matched may be determined in a plurality of second fast charging protocols supported by the second protocol chip according to the first identification result.

In an example, when the central processing unit determines that the at least one fast charging protocol to be matched is determined, if it is determined that the second electronic device does not support the first fast charging protocol according to the first recognition result, the central processing unit may screen the at least one fast charging protocol to be matched from among the plurality of second fast charging protocols according to a usage frequency of the second fast charging protocol, so as to improve charging protocol determination efficiency of the first electronic device and the second electronic device.

S203, determining a second identification result of a second protocol chip according to the power of at least one fast charging protocol to be matched; and the second identification result represents whether the second electronic equipment supports at least one protocol in the fast charging protocol to be matched.

After the central processor determines at least one fast charging protocol to be matched, it may also be determined whether the second protocol chip supports a protocol of the at least one fast charging protocol to be matched based on the power level of the at least one fast charging protocol to be matched.

In one example, when the number of the fast charging protocols to be matched is one, at this time, it is directly determined whether the second electronic device supports the fast charging protocol to be matched, so as to obtain the second identification result.

In an example, when the number of the fast charging protocols to be matched is multiple, at this time, the matching order of the fast charging protocols to be matched may be determined based on the power level corresponding to each fast charging protocol to be matched. For example, the fast charging protocols to be matched may be sequentially ordered from high to low based on the power of each fast charging protocol to be matched, and whether each fast charging protocol to be matched is supported by the second electronic device may be sequentially determined.

And S204, controlling the second electronic equipment to charge the first electronic equipment according to the second identification result.

For example, after determining the second recognition result, the charging protocol used by the first electronic device for charging may be determined based on the second recognition result, and the second electronic device may be controlled to charge the first electronic device based on the determined charging protocol.

In an example, after the second identification result is determined, if the second identification result indicates whether the second electronic device supports at least one protocol of the to-be-matched fast charging protocols, at this time, a protocol with the highest power may be selected as a protocol used when the first electronic device is charged from the to-be-matched fast charging protocols supported by the second electronic device. If the second identification result indicates that the second electronic device does not support all the fast charging protocols to be matched, a common charging protocol can be adopted for charging.

In this embodiment, the second protocol chip in the first electronic device may support a plurality of second fast charging protocols, thereby widening the range of fast charging protocols supported by the first electronic device. Furthermore, when the charging protocol identification is carried out, at least one fast charging protocol to be matched can be determined initially from the plurality of second fast charging protocols. And when the protocol identification is carried out on the quick charging protocol to be matched, the protocol identification can be carried out in sequence according to the power of the quick charging protocol to be matched, so that when the second electronic equipment supports a plurality of quick charging protocols to be matched, the quick charging protocol to be matched with the highest power can be preferentially determined in the plurality of quick charging protocols to be matched, and the charging speed of the subsequent first electronic equipment is improved.

Fig. 3 is a schematic flowchart of another charging method applied to an electronic device according to an embodiment of the present disclosure, where as shown in fig. 3, the method includes the following steps:

s301, responding to a trigger instruction, and acquiring a first identification result of a first protocol chip; the trigger instruction is used for indicating to charge the first electronic device, the first protocol chip supports the first fast charging protocol, and the first identification result represents whether the second electronic device connected with the first electronic device supports the first fast charging protocol.

This step can be referred to as step S201, and is not described herein again.

And S302, if the charging port of the second electronic device is determined to be the special charging port, determining at least one fast charging protocol to be matched from a plurality of second fast charging protocols supported by the second protocol chip according to the first identification result.

For example, in this embodiment, before the central processing unit determines the fast Charging protocol to be matched, it is further required to determine whether the Charging Port of the second electronic device is a Dedicated Charging Port (DCP).

In an example, when determining whether the charging port of the second electronic device is a dedicated charging port, the BC1.2 protocol may be identified, and specific principles herein may refer to principles in the related art, and are not described herein again.

It can be understood that, before determining the fast charging protocol to be matched, it is determined whether the charging port of the second electronic device is a dedicated charging port, and if the charging port is the dedicated charging port, it is characterized that the charging port can support the device to perform fast charging, and then the central processing unit continues to determine the fast charging protocol to be matched, thereby avoiding that when the charging port of the second electronic device is not the dedicated charging port, the central processing unit needs to perform the step of determining the fast charging protocol to be matched, which causes resource waste of the central processing unit.

In an example, when "determining at least one fast charging protocol to be matched from a plurality of second fast charging protocols supported by the second protocol chip according to the first recognition result" in step S302 is performed, at this time, the following steps may be performed:

if the first identification result indicates that the second electronic device supports the first quick charging protocol, determining a second quick charging protocol with power larger than that of the first quick charging protocol as a quick charging protocol to be matched in the plurality of second quick charging protocols; and if the second electronic equipment does not support the first quick charging protocol, determining the plurality of second quick charging protocols as the quick charging protocols to be matched.

For example, in this embodiment, when determining at least one fast charging protocol to be matched, at this time, the central processing unit may first determine a first identification result of the first protocol chip, and if the first identification result indicates that the second electronic device supports the first fast charging protocol, may obtain power of the first fast charging protocol, and select, as the fast charging protocol to be matched, a second fast charging protocol whose power is greater than the power of the first fast charging protocol, from among the plurality of second fast charging protocols. If the first identification result indicates that the second electronic device does not support the first fast charging protocol, all second fast charging protocols supported by the second protocol chip may be used as fast charging protocols to be matched.

It can be understood that, in this example, when the second electronic device supports the first fast charging protocol, the second electronic device may determine, based on the power of the first fast charging protocol, a second fast charging protocol with a power greater than that of the first fast charging protocol, and then, by the above method, for the second electronic device with a power less than that of the first fast charging protocol, matching is not required. And then the number of times of protocol identification can be reduced, so that the central processing unit can quickly obtain the charging protocol with the highest power supported by the second electronic equipment, and the charging speed is improved.

And S303, if the charging port of the second electronic device is determined not to be the special charging port, controlling the second electronic device to charge the first electronic device according to the first identification result.

For example, if the central processor determines that the charging port of the second electronic device is not the dedicated charging port, the first electronic device may be charged based on the first recognition result. For example, when the first identification result indicates that the second electronic device supports the first fast charging protocol, the second electronic device may be controlled to charge the first electronic device based on the charging current and the charging voltage indicated by the first fast charging protocol. If the first identification result indicates that the second electronic device does not support the first fast charging protocol, the central processing unit may control the second electronic device to charge the first electronic device based on the common charging protocol.

It can be understood that, when it is determined that the charging port of the second electronic device is not the dedicated charging port, the second electronic device may be controlled to charge the first electronic device directly based on the first identification result, so as to avoid the central processing unit from continuing the determination process of the fast charging protocol to be matched, and reduce the required time for determining the charging protocol.

S304, repeatedly executing the following steps until a preset stop condition is reached: determining a current quick charging protocol to be matched in the quick charging protocols to be matched according to the sequence of the power of at least one quick charging protocol to be matched from high to low; controlling the second protocol chip to operate based on the current fast charging protocol to be matched, and receiving a third identification result sent by the second protocol chip, wherein the third identification result is used for representing whether the second electronic device is the current fast charging protocol to be matched or not; the preset stopping condition is that any one of the matching of the rapid charging protocol to be matched is completed or the second electronic device supports the current rapid charging protocol to be matched.

Illustratively, after step S302, when the number of the determined fast charging protocols to be matched is plural after the fast charging protocol to be matched is determined, the following steps may be repeated: and the central processing unit determines the current quick charging protocol to be matched based on the sequence of the power of each quick charging protocol to be matched from high to low. After the fast charging protocol to be matched currently is determined, the central processing unit can control the second protocol chip to operate the fast charging protocol to be matched currently, after the second protocol chip operates the fast charging protocol to be matched currently, the second protocol chip can determine a third identification result used for representing whether the second electronic device supports the fast charging protocol to be matched currently, and if the second electronic device is determined to support the fast charging protocol to be matched currently, a repeated circulation step can be skipped; or when the fast charging protocol to be matched is the last fast charging protocol to be matched in the sequence from high power to low power, at this time, after the third recognition result is determined, the repeated circulation step can be skipped; however, when the third identification result indicates that the second electronic device does not support the current fast charging protocol to be matched and the current fast charging protocol to be matched is not the last fast charging protocol to be matched, at this time, the central processing unit continues to determine the current fast charging protocol to be matched in the multiple fast charging protocols to be matched based on the power level, that is, the above process is continuously repeated until the repeated loop step is skipped.

In an example, a second protocol chip may be disposed in the first electronic device, and a plurality of second fast charging protocols supported by the second protocol chip may be stored in the second protocol chip in advance, so as to avoid that the second protocol chip needs to spend time writing the fast charging protocol to be matched into the second protocol chip when determining the second identification result.

In one example, the number of second protocol chips is one; the second protocol chip comprises two firmware storage areas; the two firmware storage areas are used for respectively storing the first two second quick charging protocols with the maximum charging power values in the plurality of second quick charging protocols.

For example, in this embodiment, in order to avoid a problem that the second protocol chip stores more second fast charging protocols and occupies more memory, in this example, two firmware storage areas may be arranged in the second protocol chip, and the two firmware storage areas are used to respectively store the first two of the protocols with the highest power in the plurality of second fast charging protocols. The other second fast charging protocols can be written into the central processing unit, and when the protocol identification needs to be carried out on the second fast charging protocol in the central processing unit, the central processing unit can write the second fast charging protocol in the central processing unit into the second protocol chip so that the second protocol chip can carry out the protocol identification.

In addition, the plurality of second fast charging protocols stored in the central processing unit can update the charging protocol along with the updating of the first electronic device, so that the second protocol chip can support the plurality of second fast charging protocols

It can be understood that, by storing the two second fast charging protocols, the memory space occupied in the second protocol chip can be reduced, and the two stored fast charging protocols are the first two of the protocols with the highest power in the plurality of second fast charging protocols, so that it can be preferentially determined whether the second electronic device supports the protocol with the highest power written in the second protocol chip.

In one example, the number of second protocol chips is one; the second protocol chip comprises two firmware storage areas; the two firmware storage areas are used for respectively storing the first two second quick charging protocols with the maximum charging power values in the plurality of second quick charging protocols; after controlling the second protocol chip to operate based on the fast charging protocol to be matched currently, the method further includes:

if it is determined that the next to-be-matched fast charging protocol of the current to-be-matched fast charging protocol is not stored in the two firmware storage areas in the second protocol chip, writing the next to-be-matched fast charging protocol of the current to-be-matched fast charging protocol into a first firmware storage area in the second protocol chip, wherein the first firmware storage area is a firmware storage area which is not used for storing the current to-be-matched fast charging protocol in the two firmware storage areas.

Illustratively, the second protocol chip includes a firmware storage area 1 and a firmware storage area 2, the firmware storage area 1 stores the fast charging protocol 1 to be matched, the firmware storage area 2 stores the fast charging protocol 2 to be matched, after performing protocol identification on the fast charging protocol 1 to be matched in the firmware storage area 1, it is determined that the second electronic device does not support the fast charging protocol 1 to be matched, the central processor controls the second protocol chip to run the fast charging protocol 2 to be matched, and since the central processor determines that the latter protocol of the fast charging protocol 2 to be matched (the fast charging protocol 3 to be matched) is not stored in the firmware storage area 1 and the firmware storage area 2, the fast charging protocol 3 to be matched can be stored in the firmware storage area 1 (i.e., the firmware storage area of the two firmware storage areas where the protocol currently running by the second protocol chip is not stored), the latter protocol of the fast charging protocol 2 to be matched is determined based on the sequence of the power of each fast charging protocol to be matched from high to low.

It can be understood that, in this embodiment, when the second protocol chip is controlled to run the current fast charging protocol to be matched, the fast charging protocol to be matched later than the current fast charging protocol to be matched may be written into the firmware storage area where the second protocol chip does not store the current fast charging protocol to be matched, and then the second protocol chip may be conveniently subjected to protocol replacement by setting two firmware partitions, so that time consumed for protocol replacement is saved, and the problem that when only one firmware storage area is included in the second protocol chip, the time consumed for replacing the protocol in the firmware storage area is long, which results in long charging time is also avoided.

In one example, in order to ensure that the protocols stored in the two firmware storage areas in the second protocol chip are the first two second fast charging protocols with the maximum charging power value in the plurality of second fast charging protocols, after the charging of the first electronic device is finished, the first two second fast charging protocols with the maximum charging power value in the plurality of second fast charging protocols are also written into the two firmware storage areas again.

S305, determining a second identification result of the second protocol chip based on at least one third identification result.

For example, after jumping out of the loop step in step S304, the central processor may determine the second recognition result of the second protocol chip based on the received third recognition result.

For example, if the central processing unit determines that the last third identification result received when the loop is skipped indicates that the second electronic device supports the current fast charging protocol to be matched, the second identification result of the second protocol chip is used to indicate that the second electronic device supports at least one protocol of the fast charging protocols to be matched, and the second electronic device supports the current fast charging protocol to be matched indicated in the last third identification result; and if the central processing unit determines that the last third identification result received when the loop is jumped out represents that the second electronic equipment does not support the current rapid charging protocol to be matched, the second identification result of the second protocol chip is used for representing that the second electronic equipment does not support the protocol in at least one rapid charging protocol to be matched.

It can be understood that, in this example, when the second protocol chip determines the second identification result, the central processing unit may switch between the to-be-matched fast charging protocols by controlling the protocol running in the second protocol chip, so as to ensure that the second protocol chip determines whether the second electronic device supports the to-be-matched fast charging protocol by running the to-be-matched fast charging protocol.

S306, if the second identification result of the second protocol chip indicates that the second electronic device supports at least one protocol in the to-be-matched fast charging protocol, taking the current to-be-matched fast charging protocol supported by the second electronic device and represented by the third identification result as a protocol result, wherein the protocol result is used for indicating the protocol used when the first electronic device is charged.

For example, in this embodiment, after the central processing unit obtains the second identification result of the second protocol chip, if the second protocol chip represents that the second electronic device supports a protocol in at least one to-be-matched fast charging protocol, at this time, the current to-be-matched fast charging protocol indicated in the third identification result obtained when the step S304 is skipped may be used as a protocol used when the first electronic device is charged this time, that is, the to-be-matched fast charging protocol indicated in the third identification is used as a protocol result.

S307, if the second identification result of the second protocol chip represents that the second electronic device does not support the protocol in the at least one fast charging protocol to be matched, determining a protocol result based on the first identification result.

For example, in this embodiment, after the central processing unit obtains the second identification result of the second protocol chip, if the second protocol chip indicates that the second electronic device does not support all protocols in the at least one fast charging protocol to be matched, at this time, the protocol result adopted when the first electronic device is charged this time may be determined based on the first identification result obtained by the central processing unit before.

In one example, step S307 includes the steps of:

if the second identification result of the second protocol chip represents that the second electronic equipment does not support the protocol in at least one fast charging protocol to be matched, and the first identification result indicates that the first electronic equipment does not support the first fast charging protocol, the common charging protocol is used as a protocol result;

and if the second identification result of the second protocol chip represents that the second electronic equipment does not support the protocol in at least one fast charging protocol to be matched, and the first identification result indicates that the first electronic equipment supports the first fast charging protocol, the first fast charging protocol is used as a protocol result.

For example, when the central processing unit determines that the second identification result of the second protocol chip indicates that the second electronic device does not support the protocol in the at least one fast charging protocol to be matched, the central processing unit may determine, based on the first identification result, the charging protocol used by the first electronic device for charging this time. At this time, if the first identification result indicates that the second electronic device supports the first fast charging protocol supported by the first protocol chip, the first fast charging protocol may be used as a charging protocol for the first electronic device to be charged at this time. In addition, if the first identification result indicates that the second electronic device does not support the first fast charging protocol, the first electronic device can only select the common charging protocol as the protocol result.

It can be understood that, in this example, when the second electronic device does not support all the fast charging protocols to be matched, the first fast charging protocol with a charging speed faster than that of the normal charging protocol may be preferentially selected, so as to increase the charging speed of the first electronic device, and if the second electronic device does not support the first fast charging protocol, the first electronic device may be charged based on the normal charging protocol, so that it is ensured that the second electronic device can charge the first electronic device.

And S308, determining the charging information of the main charging chip and the charging information of the auxiliary charging chip in the first electronic equipment based on the charging voltage and the charging current corresponding to the protocol result, and controlling the second electronic equipment to charge the first electronic equipment.

For example, in the present embodiment, a main charging chip and an auxiliary charging chip may be provided in the first electronic device. The main charging chip can adjust a charging signal transmitted from the second electronic device to the first electronic device, and then the adjusted signal is used as the charging signal of the first electronic device to charge the first electronic device. In addition, when the power of the protocol used by the first electronic device for charging is greater than the maximum power that can be supported by the main charging chip, the auxiliary charging chip can be turned on, the auxiliary charging chip and the main charging chip jointly adjust the charging signal input into the first electronic device by the second electronic device, and the signals adjusted by the two charging chips are used as the charging signal of the first electronic device, so that the process of charging the first electronic device by the second electronic device is completed.

Therefore, after determining the protocol result, the central processing unit may determine, based on the charging current and the charging voltage set in the protocol indicated by the protocol result, current charging information of the main charging chip and current charging information of the auxiliary charging chip in the first electronic device, where the charging information of the main charging chip is used to indicate a current value and a voltage value allowed to pass through the main charging chip in the current charging process of the first electronic device, and the charging information of the auxiliary charging chip is used to indicate a current value and a voltage value allowed to pass through the auxiliary charging chip in the current charging process of the first electronic device. When the current value and the voltage value in the charging information of the auxiliary charging chip are both 0, the auxiliary charging chip can be used for representing the charging process, and when the power of the protocol used by the first electronic device for charging is smaller than the maximum power which can be supported by the main charging chip, the process of charging the first electronic device is realized by only using the main charging chip.

It can be understood that, in this embodiment, the main charging chip and the auxiliary charging chip may be disposed in the first electronic device, so as to avoid a phenomenon that the main charging chip is burned out when the maximum power supported by the main charging chip is less than the power of the protocol used by the first electronic device this time.

In this embodiment, before determining the fast charging protocol to be matched, it is determined whether the charging port of the second electronic device is a dedicated charging port, and if the charging port is the dedicated charging port, the central processing unit continues to determine the fast charging protocol to be matched, thereby avoiding resource waste of the central processing unit due to the fact that the central processing unit needs to perform the step of determining the fast charging protocol to be matched when the charging port of the second electronic device is not the dedicated charging port. In addition, when the second electronic device supports the first fast charging protocol, the second fast charging protocol with the power larger than that of the first fast charging protocol may be determined in the second electronic device based on the power of the first fast charging protocol, and further, by the above method, matching is not required for the second electronic device with the power smaller than that of the first fast charging protocol. And then the number of times of protocol identification can be reduced, so that the central processing unit can quickly obtain the charging protocol with the highest power supported by the second electronic equipment, and the charging speed is improved.

In some embodiments, the first electronic device may further be configured to charge a third electronic device connected to the first electronic device, and when the first electronic device needs to charge the third electronic device, at this time, the central processing unit in the first electronic device may control the magnitude of the charging signal output by the first electronic device this time based on a charging protocol used by the third electronic device for charging this time, which is determined by the third electronic device, so as to implement a process that the first electronic device charges the third electronic device, specifically, the central processing unit may control the charging signal provided by the first electronic device to the third electronic device by controlling the magnitude of the charging signal output by the battery through the main charging chip.
