The mobile power supply 120 includes an energy conversion unit 1201, a control unit 1202, and a battery 1203; the power adapter 110 is connected to the energy conversion unit 1201 and the control unit 1202 respectively, and the control unit 1202 is further connected to the energy conversion unit 1201, and is configured to control a process of converting energy of the charging voltage and the charging current output by the power adapter 110 by the energy conversion unit 1201; the energy conversion unit 1201 is connected to the battery 1203, and the battery 1203 may be charged with the output voltage and the output current obtained by the energy conversion unit 1202. Those skilled in the art will appreciate that the configuration of the mobile power supply 120 shown in fig. 1 does not constitute a limitation of the mobile power supply, and that the mobile power supply may include more or fewer components than shown, or some components may be combined, or a different arrangement of components.
It should be noted that the power adapter 110 and the mobile power supply 120 are connected by a charging connection line, so that the two can communicate with each other through a charging handshake protocol, thereby establishing a communication connection. Specifically, the connection between the power adapter 110 and the mobile power supply 120 through the charging connection line may mean that an input interface (such as a Universal Serial Bus (USB) interface) disposed on the mobile power supply 120 is connected to an interface (such as a USB interface) disposed on the power adapter 110 through the charging connection line, so that a charging handshake protocol can be communicated between the power adapter 110 and the mobile power supply 120 to enable the mobile power supply 120 to be in a charging connection state, and then the power adapter 110 charges the battery 1203 in the mobile power supply 120. More specifically, power lines (e.g., labeled VCC and GND) in the charging connection line are connected to the energy conversion unit 1201, and are used for inputting the charging voltage and the charging current output by the power adapter 110 into the energy conversion unit 1201, and performing energy conversion on the charging voltage and the charging current by the energy conversion unit 1201; data lines (e.g., labeled D + and D-) in the charging connection line are connected to the control unit 1202 for communicating with the power adapter 110 and identifying the type of the power adapter 110; then, the control unit 1202 is further connected to the energy conversion unit 1201, and is configured to control the energy conversion unit 1201 to perform an energy conversion process, and finally load the output voltage and the output current obtained by the energy conversion unit 1201 to the battery 1203 for charging.

Based on the charging control system 10 shown in fig. 1, the following describes in detail various embodiments of the present application with reference to the drawings.

s204: and receiving the charging voltage and the charging current corresponding to the charging power output by the power adapter according to the control instruction, and charging the battery in the mobile power supply.
It should be noted that the types of the power adapter may include a first type adapter, a second type adapter, and a third type adapter, and correspondingly, the charging types supported by the mobile power supply may include a first charging type, a second charging type, and a third charging type; here, the charging type supported by the mobile power supply and the type of the power adapter have a matching relationship, and the charging powers output by different types of power adapters are also different; that is, there is a corresponding relationship among the charging type supported by the mobile power supply, the type of the power adapter, and the charging power output by the power adapter.
It should be further noted that, for the charging types supported by the mobile power supply, the mobile power supply further has a charging protocol corresponding thereto. Specifically, for a first type of adapter, the charging protocol matched with the adapter is a first charging protocol; aiming at the second type adapter, the matched charging protocol is a second charging protocol; for the third type of adapter, the charging protocol matched with the adapter is a third charging protocol. Therefore, the charging protocol adopted by the mobile power supply, the charging type supported by the mobile power supply, the type of the power adapter and the charging power output by the power adapter have a corresponding relation.
Exemplarily, if the first type adapter is an ultrafast charging adapter, the corresponding output first charging power of the first type adapter is 10V/5A, and the matching result with the charging type supported by the mobile power supply is the first charging type, at this time, the charging protocol adopted by the mobile power supply for charging is the first charging protocol; if the second type adapter is a quick charging adapter, the corresponding output second charging power is 5V/4A, the matching result with the charging type supported by the mobile power supply is the second charging type, and the charging protocol adopted by the mobile power supply for charging is the second charging protocol; if the third type adapter is a common charging adapter, the correspondingly output third charging power is 5V/1A, the matching result with the charging type supported by the mobile power supply is the third charging type, and the charging protocol adopted by the mobile power supply for charging is the third charging protocol. In practical applications, no matter the first type adapter and the corresponding first charging power, first charging type and first charging protocol, or the second type adapter and the corresponding second charging power, second charging type and second charging protocol, or even the third type adapter and the corresponding third charging power, third charging type and third charging protocol, are specifically set according to actual situations, and this is not specifically limited in the embodiment of the present application.
In the technical scheme shown in fig. 2, the method is applied to a mobile power supply, and includes firstly identifying a type of a power adapter, then determining a charging protocol used for charging the mobile power supply according to the identified type of the power adapter and a matching result of a charging type supported by the mobile power supply, and sending a control instruction to the power adapter based on the charging protocol; the control instruction is used for instructing the power adapter to output charging power corresponding to the type of the power adapter; therefore, the power adapter can be compatible with different types of power adapters, and the output capacity of the power adapter can be maximized; finally, receiving a charging voltage and a charging current corresponding to the charging power output by the power adapter according to the control instruction, and charging a battery in the mobile power supply; the mobile power supply can be compatible with different types of power adapters, and meanwhile, the output capacity of the power adapters can be maximized, so that the charging efficiency is improved.

Specifically, the connection between the mobile power source and the power adapter through the charging connection line may mean that an input interface (for example, a USB interface) disposed on the mobile power source is connected to an interface (for example, a USB interface) disposed on the power adapter through the charging connection line, so that the mobile power source and the power adapter can communicate with a charging handshake protocol, and a communication connection between the mobile power source and the power adapter is conveniently established.
It should be further noted that the charging connection line includes a power line and a data line; the power line comprises a VCC power line and a GND power line, and the data line comprises a D + data line and a D-data line; here, the power line is used for charging connection of the power adapter for the mobile power supply, and the data line is used for communication connection of the power adapter and the mobile power supply; based on the communication connection established by the data line between the power adapter and the power adapter, the type of the power adapter can be identified, and a control instruction can be sent to the power adapter subsequently to control the power adapter to output the charging voltage and the charging current corresponding to the power adapter.
In some embodiments, the identifying the type of the power adapter comprises:
receiving a signal transmitted by the power adapter through a data line based on communication between the mobile power supply and the power adapter;
and identifying the type of the power adapter according to the signal.
It should be noted that, after the communication connection is established between the mobile power supply and the power adapter, the mobile power supply may receive a signal transmitted by the power adapter through a data line (such as a D + data line and a D-data line); the type of power adapter is identified from the received signal. Specifically, the received signal may be compared with a preset signal policy, for example, if the received signal satisfies a first policy, the type of the power adapter may be identified as a first type adapter; if the received signal meets a second strategy, the type of the power adapter can be identified as a second type adapter; if the received signal meets a third strategy, the type of the power adapter can be identified as a third type adapter; in practical application, the first policy, the second policy, and the third policy are specifically set according to practical situations, and this is not specifically limited in this embodiment of the application.

In some embodiments, the sending control instructions to the power adapter based on the charging protocol includes:
if the matching result is a first charging type, determining that a charging protocol adopted by the mobile power supply is a first charging protocol, and sending a first control instruction to the power adapter according to the first charging protocol; the first control instruction is used for instructing the power adapter to output first charging power corresponding to a first charging type;
if the matching result is a second charging type, determining that a charging protocol adopted by the mobile power supply is a second charging protocol, and sending a second control instruction to the power adapter according to the second charging protocol; the second control instruction is used for instructing the power adapter to output second charging power corresponding to a second charging type; wherein the second charging power is less than the first charging power;
if the matching result is a third charging type, determining that a charging protocol adopted by the mobile power supply for charging is a third charging protocol, and sending a third control instruction to the power adapter according to the third charging protocol; the third control instruction is used for instructing the power adapter to output third charging power corresponding to a third charging type; wherein the third charging power is less than the second charging power.
It should be noted that, after the type of the power adapter is identified, the identified type of the power adapter may be matched with a charging type supported by the mobile power supply; and then according to the obtained matching result, sending a control instruction to the power adapter through the D + data line and the D-data line, wherein the control instruction is used for informing the power adapter to output charging power corresponding to the type of the power adapter.
For example, taking the charging control system 10 shown in fig. 1 as an example, the power adapter 110 and the mobile power supply 120 are connected through a charging connection line, and when the handshake protocol between the two is successfully established, the control unit 1202 in the mobile power supply 120 may perform data communication with the power adapter 110 through a D + data line and a D-data line; if the signal received by the control unit 1202 through the D + data line and the D-data line satisfies the first policy, it may be recognized that the type of the power adapter is a first type adapter, at this time, the matching result obtained by the control unit 1202 is a first charging type, it is determined that the charging protocol used for charging the mobile power supply 120 is a first charging protocol according to the matching result, a first control instruction is sent to the power adapter 110 according to the first charging protocol, and the power adapter 110 may output a first charging power corresponding to the first charging type according to the first control instruction, for example, the first charging power output by the first type adapter is 10V/5A (the first voltage corresponding to the first charging power is 10V, and the first current is 5A); if the signal received by the control unit 1202 through the D + data line and the D-data line satisfies the second policy, it may be recognized that the type of the power adapter is a second type adapter, at this time, the matching result obtained by the control unit 1202 is a second charging type, it is determined that the charging protocol used for charging the mobile power supply 120 is a second charging protocol according to the matching result, a second control instruction is sent to the power adapter 110 according to the second charging protocol, and the power adapter 110 may output a second charging power corresponding to the second charging type according to the second control instruction, for example, the second charging power output by the second type adapter is 5V/4A (the second voltage corresponding to the second charging power is 5V, and the second current is 4A); if the signal received by the control unit 1202 through the D + data line and the D-data line satisfies the third policy, it may be recognized that the type of the power adapter is a third type adapter, at this time, the matching result obtained by the control unit 1202 is a third charging type, it is determined that the charging protocol used for charging the mobile power supply 120 is a third charging protocol according to the matching result, a third control instruction is sent to the power adapter 110 according to the third charging protocol, and the power adapter 110 may output a third charging power corresponding to the third charging type according to the third control instruction, for example, the third charging power output by the third type adapter is 5V/1A (a third voltage corresponding to the third charging power is 5V, and a third current is 1A); in this way, the mobile power supply can enable different types of power adapter to output charging power corresponding to the types, so that the output capacity of the power adapter is maximized.

and performing energy conversion on the charging voltage and the charging current based on the working mode, and loading the output voltage and the output current obtained after conversion to the battery for charging.
It should be noted that after the mobile power supply receives the charging voltage and the charging current corresponding to the charging power output by the power adapter according to the control instruction, the mobile power supply also performs energy conversion on the charging voltage and the charging current through the energy conversion unit, and the whole energy conversion process is controlled by the control unit; the control unit determines the working mode of the energy conversion unit by judging the current conditions (such as target battery voltage and target battery current) of the mobile power supply; if the target battery voltage required by the mobile power supply currently is higher than the charging voltage provided by the power adapter, the energy conversion unit can be determined to be in a boosting mode, and the charging voltage and the charging current are subjected to boosting conversion; if the target battery voltage required by the mobile power supply at present is lower than the charging voltage provided by the power adapter, it can be determined that the energy conversion unit is in a voltage reduction mode, and the charging voltage and the charging current are subjected to voltage reduction conversion; and finally, loading the output voltage and the output current obtained after conversion to a battery for charging.
