Fig. 2 is a flowchart of a method for determining a charging protocol in an embodiment. The method for determining the charging protocol in this embodiment is described by taking the first device running in FIG. 1 as an example. As shown in Figure 2, the method for determining the charging protocol includes:

S201. Receive charging protocol information sent by the second device; the charging protocol information includes identifications of at least two charging protocols supported by the second device.

Wherein, the identification of at least two charging protocols supported by the second device may be the name of the charging protocol supported by the second device, or the code of the charging protocol supported by the second device, or may be the charging protocol supported by the second device. The manufacturer's name and the like of the manufacturer to whom the protocol belongs are not limited in this embodiment of the application. In this embodiment, after the first device and the second device establish a communication connection, the second device may send charging protocol information including identifications of at least two charging protocols it supports to the first device. For example, if the charging protocols supported by the second device include charging protocol A, charging protocol B, and charging protocol C, the second device carries the identification of charging protocol A, charging protocol B, and charging protocol C in the charging The protocol information is sent to the first device. It should be noted that the at least two charging protocols supported by the second device may be charging protocols belonging to different manufacturers, or may be charging protocols corresponding to different charging powers. Optionally, the first device may be a charging device, and the second device may be a power supply device, or, the first device may be a power supply device, and the second device may be a charging device.

S202. Determine a target charging protocol based on the at least two charging protocols supported by the second device and the charging protocol supported by the first device.

In this embodiment, after receiving the charging protocol information sent by the second device, the first device may determine one of the charging protocols supported by both the first device and the second device as the target charging protocol, that is, from the second One charging protocol among the at least two charging protocols supported by the device and the charging protocols supported by the first device is determined as the target charging protocol. Alternatively, it is also possible to determine multiple charging protocols supported by the first device and the second device, and then select one of the charging protocols as the target charging protocol according to some selection mechanism, for example, according to the priority order of the commonly supported charging protocols Determine the target charging protocol, or determine the target charging protocol according to the rated power of commonly supported charging protocols, and so on.

Exemplarily, the charging protocol supported by the second device includes charging protocol A, charging protocol B, and charging protocol C, and the charging protocol supported by the first device includes charging protocol A and charging protocol C as an example. After receiving the charging protocol information sent by the second device, a device determines that charging protocol A and charging protocol C are charging protocols supported by both, and then determines the target charging protocol from protocol A and protocol C. Optionally, The target charging protocol determined by the first device may be protocol A or protocol C. It can be understood that the target charging protocol determined by the first device may be the charging protocol with the highest priority among the charging protocols supported by the first device and the second device, or may be the charging protocol supported by the first device and the second device. The charging protocol with the highest charging power among the protocols is not limited in this embodiment of the present application.

S203. Send the identifier of the target charging protocol to the second device.

In this embodiment, after the first device determines the target charging protocol, it sends the identification of the target charging protocol to the second device, and continues to use the charging protocols supported by the second device including three protocols: protocol A, protocol B, and protocol C. The charging protocol supported by the second device includes protocol A and protocol C as an example. If the target charging protocol determined by the first device is protocol A, the first device sends the identifier of protocol A to the second device; if the first The target charging protocol determined by the device is protocol C, and the first device sends the identifier of protocol C to the second device.

After the second device receives the identification of the target charging protocol, the first device performs a charging process with the second device based on the target charging protocol. For example, if the first device is a power supply device and the second device is a charging device, the first device charges the second device according to the target charging protocol; if the first device is a charging device and the second device is a power supply device, the second device The first device is charged according to the target charging protocol.

In this embodiment, when both the first device and the second device support multiple charging protocols, the first device receives the charging protocol information sent by the second device, since the charging protocol information includes at least one of the charging protocols supported by the second device. The identification of the two charging protocols is equivalent to the second device sending multiple charging protocols to the first device at one time, and the first device can directly determine the target charging protocol based on the multiple charging protocols supported by the second device and the charging protocols supported by itself. The protocol avoids the process of selecting the charging protocol multiple times, thereby shortening the time for the first charging device to select the charging protocol, and reducing the interaction time between the first device and the second device before charging.

In the above scenario of determining the target charging protocol based on at least two charging protocols supported by the second device and the charging protocol supported by the first device, when both the first device and the second device support multiple charging protocols, the second A device determines multiple commonly supported charging protocols based on at least two charging protocols supported by the second device and the charging protocol supported by the first device. For this scenario, in this embodiment of the application, the above-mentioned target charging protocol is the second One of the charging protocols supported by both the device and the first device.

In this embodiment, after the target charging protocol is determined, the first device performs a charging process with the second device based on the target charging protocol. In the charging process, the power supply device supplies power to the charging device according to the target charging protocol. The charging protocol can specify the authentication, communication sequence, message format, data packet format, charging exception handling, etc. between the power supply equipment and the charging equipment. For example, when the power supply device and the charging device perform charging according to the target charging protocol, the power supply device can send the voltage/current information it can provide to the charging device in the response message format according to the target charging protocol, and the charging device according to its own needs, After selecting the voltage/current, send feedback information to the power supply device, and the power supply device will output the charging voltage/current according to the voltage/current to charge the charging device.

In this embodiment, the target charging protocol is one of the charging protocols supported by both the second device and the first device, that is, any one of the charging protocols supported by the second device and the first device is determined Charge protocol for the target. Optionally, the charging protocol supported by both the second device and the first device may be a charging protocol with the same identification, or a charging protocol with the same charging power, or a charging protocol with the same charging current, etc. No limitation is imposed in the application examples. For example, the charging protocols supported by the second device include charging protocol A, charging protocol B, and charging protocol C, and the charging protocols supported by the first device include charging protocol A and charging protocol C, wherein the charging protocols supported by the second device A and charging protocols The charging protocol A supported by one device has the same protocol identifier, and the charging protocol C supported by the second device and the charging protocol C supported by the first device have the same protocol identifier, then the first device determines the charging protocol A and charging protocol C as A charging protocol supported by both the second device and the first device. Further, optionally, the first device may determine a charging protocol as a target from the charging protocols supported by both the second device and the first device according to the priorities of the charging protocols supported by both the second device and the first device The charging protocol may also be determined as the target charging protocol from the charging protocols supported by both the second device and the first device according to the charging power of the charging protocols supported by both the second device and the first device. For example, if the priority of charging protocol A is greater than that of charging protocol C, the first device determines charging protocol A as the target charging protocol. Alternatively, if the charging power of the charging protocol A is greater than the charging power of the charging protocol C, the first device determines the charging protocol A as the target charging protocol.

In this embodiment, the target charging protocol is one of the charging protocols supported by both the second device and the first device, and by determining one of the charging protocols supported by both the second device and the first device as the target charging protocol, Improved the reliability of determining the target charging protocol.

In the scenario where the target charging protocol is determined based on at least two charging protocols supported by the second device and the charging protocol supported by the first device, the charging protocols supported by both the second device and the first device include two or more , the first device can determine the target charging protocol based on the charging protocols supported by both the second device and the first device, including the priority of two or more charging protocols, or based on the charging protocols supported by both the second device and the first device The protocol includes the charging power of two or more charging protocols to determine the target charging protocol. The following will determine the target charging for the first device based on two or more charging protocols supported by both the second device and the first device. The protocol process is described in detail:

First, if the charging protocols supported by both the second device and the first device include two or more charging protocols, the charging protocol with the highest priority among the two or more charging protocols is determined as the target charging protocol.

In this embodiment, if the first device determines that there are two or more charging protocols supported by both the second device and the first device, the first device The target charging protocol is determined at the first level, that is, the first device determines the charging protocol with the highest priority among the two or more charging protocols supported by both the second device and the first device as the target charging protocol. Continuing to take the example that the charging protocols supported by the second device include charging protocol A, charging protocol B, and charging protocol C, and the charging protocols supported by the first device include charging protocol A and charging protocol C, in this scenario, the second device and The charging protocols supported by the first device are charging protocol A and charging protocol C, and if the priority of the charging protocol is charging protocol A>charging protocol C, then the first device determines charging protocol A as the above-mentioned target charging protocol.

In this embodiment, the first device determines the charging protocol with the highest priority among the two or more charging protocols supported by the second device and the first device as the target charging protocol. A device selects a charging protocol time, and the selected target charging protocol is better.

Second, if the charging protocols supported by both the second device and the first device include two or more than two charging protocols, the charging protocol with the highest charging power among the two or more charging protocols is determined as the target charging protocol:

In this embodiment, if the first device determines that there are two or more charging protocols supported by the second device and the first device, the first device The charging power determines the target charging protocol, that is, the first device determines the charging protocol with the highest charging power among the two or more charging protocols supported by both the second device and the first device as the target charging protocol. Continuing to take the example that the charging protocols supported by the second device include charging protocol A, charging protocol B, and charging protocol C, and the charging protocols supported by the first device include charging protocol A and charging protocol C, in this scenario, the second device and The charging protocols supported by the first device are charging protocol A and charging protocol C. If the charging power of charging protocol C is greater than that of charging protocol A, the first device determines charging protocol C as the target charging protocol.

It should be noted that, in order to reduce the signaling of the charging protocol information sent by the second device to the first device, in the scenario of the charging protocol information sent by the second device to the first device, the charging protocol information sent by the second device The charging power of each charging protocol supported by the second device may be included, and the level of charging power of each charging protocol supported by the second device may also be included.

In this embodiment, the first device determines the charging protocol with the highest charging power as the target charging protocol among the two or more charging protocols supported by the second device and the first device. A time for the device to select a charging protocol.

If the above-mentioned charging protocols supported by both the second device and the first device include two or more, then the first device will use the two or more charging protocols supported by the second device and the first device. In the scenario where the charging protocol with the highest power is determined as the target charging protocol, the charging protocols supported by both the second device and the first device may include a first candidate protocol and a second candidate protocol, where the first candidate protocol and the second candidate protocol are For charging protocols owned by different manufacturers, in this scenario, in one embodiment, if the charging protocols supported by both the second device and the first device include the first candidate protocol and the second candidate protocol, and the charging protocol of the second candidate protocol If the power is greater than the sum of the charging power of the first candidate protocol and the preset power increment, the second candidate protocol is determined as the target charging protocol.

In this embodiment, the first candidate protocol and the second candidate protocol are protocols owned by different manufacturers. For example, the first candidate protocol may be a protocol owned by the first manufacturer, and the second candidate protocol may be a protocol owned by the second manufacturer. When the first candidate protocol is the operator's own protocol, in this scenario, in order to more flexibly determine the target charging protocol, the first device may sum the charging power of the first candidate protocol and a preset power increment, To obtain the corrected power of the first candidate protocol, for example, the preset power increment can be 20, then the first device can sum the charging power of the first candidate protocol and 20 to obtain the corrected power of the first candidate protocol, and the above The charging power of the second candidate protocol is compared with the correction power of the first candidate protocol. If the first device determines that the charging power of the second candidate protocol is greater than the correction power of the first candidate protocol, the first device will The protocol identified above is the target charging protocol. It can be understood that, in this embodiment, the charging power of the first candidate protocol is the corrected power. In this case, if the charging power of the second candidate protocol is still greater than the corrected power of the first candidate protocol, it means The charging power of the protocol is the maximum power, so the second candidate protocol is determined as the target charging protocol, ensuring the accuracy of the determined target charging protocol.

In this embodiment, if the charging protocols supported by both the second device and the second device include the first candidate protocol and the second candidate protocol, and the charging power of the second candidate protocol is greater than the charging power of the first candidate protocol and the preset power In the sum of the increments, the first device determines the second candidate protocol as the target charging protocol, so that the scenario adaptability of the protocol selection method is more flexible.

Scenario 3: If both the second device and the first device support two or more charging protocols, the first device can use the following two methods to determine the target charging protocol, and the following two determine the target charging protocol respectively The method is explained:

Method A: If the charging protocols supported by both the second device and the first device include two or more, determine the third candidate charging protocol with the highest priority among the two or more charging protocols as the target charging protocol; The third candidate charging protocol is a preset number of charging protocols determined from two or more charging protocols in descending order of charging power.

In this embodiment, if the first device determines that both the second device and the first device support two or more charging protocols, after receiving the charging protocol information sent by the second device, the first device In the information, the charging power of the charging protocol supported by the second device is determined from the charging power of the second device and the first device, including two or more charging protocols, according to the order of charging power from large to small. Charging protocol, for example, two or more charging protocols supported by both the second device and the first device are charging protocol A, charging protocol C and charging protocol D, and the first device receives the charging protocol sent by the second device In the information, the power of charging protocol A is 50W, the power of charging protocol C is 20W, and the power of charging protocol D is 10W, then the first device determines charging protocol A and charging protocol C as the third candidate charging protocol, and then sets the priority The highest third candidate charging protocol is determined as the target charging protocol. For example, the determined third candidate charging protocol is charging protocol C and charging protocol D, and the priority of charging protocol C is higher than that of charging protocol D, then the first device determines charging protocol C as the target charging protocol, and for example , the determined third candidate charging protocol is charging protocol A, charging protocol C, and charging protocol D, and the priority of charging protocol A is higher than that of charging protocol C, and the priority of charging protocol C is higher than that of charging protocol D level, the first device may determine charging protocol A as the target charging protocol.

In this embodiment, the first device can quickly sort the charging protocols supported by both the second device and the first device according to the charging power according to the charging power of the charging protocols supported by the second device and the first device, and quickly A preset number of third candidate charging protocols are determined therefrom, so that the first device can quickly determine the third candidate charging protocol with the highest priority as the target charging protocol, because the determined target charging protocol is the third candidate charging protocol with the highest priority In this way, the two factors of the priority and power of the charging protocol are taken into account, making the determined target charging protocol more reliable and more adaptable to the scene.

Method B: If the charging protocols supported by both the second device and the first device include two or more, determine the fourth candidate charging protocol with the highest charging power among the two or more charging protocols as the target charging protocol; The fourth candidate charging protocol is a preset number of charging protocols determined from two or more charging protocols in descending order of priority.

In this embodiment, if the first device determines that both the second device and the first device support two or more charging protocols, after receiving the charging protocol information sent by the second device, the first device The priority of the charging protocol supported by the second device in the information, from the two or more charging protocols supported by both the second device and the first device, a preset number of charging protocols are determined in order of priority from high to low. Charging protocol, for example, two or more charging protocols supported by both the second device and the first device are charging protocol A, charging protocol C and charging protocol D, and the first device receives the charging protocol information sent by the second device The priority of charging protocol A is higher than that of charging protocol C, and the priority of charging protocol C is higher than that of charging protocol D, then the first device determines charging protocol A and charging protocol C as the fourth candidate charging protocol , and then determine the fourth candidate charging protocol with the highest charging power as the target charging protocol. For example, the determined fourth candidate charging protocol is charging protocol C and charging protocol D, and the charging power of charging protocol C is greater than the charging power of charging protocol D, then the first device determines charging protocol C as the target charging protocol, and for another example, The determined fourth candidate charging protocol is charging protocol A, charging protocol C and charging protocol D, and the charging power of charging protocol A is greater than the charging power of charging protocol C, and the charging power of charging protocol C is greater than the charging power of charging protocol D, then The first device may determine charging protocol A as the target charging protocol.

In this embodiment, the first device can quickly sort the charging protocols supported by both the second device and the first device according to the priority according to the priorities of the charging protocols supported by both the second device and the first device, and quickly select Determine a preset number of fourth candidate charging protocols, so that the first device can quickly determine the fourth candidate charging protocol with the largest charging power as the target charging protocol, because the determined target charging protocol is the fourth candidate charging protocol with the largest charging power , which takes into account the priority and power of the charging protocol, making the determined target charging protocol more reliable and more adaptable to the scene.

Optionally, the first device may send a handshake request to the second device, and after receiving the handshake request from the first device, the second device sends a response message to the first device to establish a communication connection with the second device. It may also be that the second device sends a handshake request to the first device, and after receiving the handshake request sent by the second device, the first device sends a response message to the second device to establish a communication connection with the first device. Optionally, the above-mentioned target charging protocol may be the preset standard communication protocol. It can be understood that the first device and the second device can communicate based on a preset standard communication protocol. If the standard communication protocol supports the communication between the first device and the charging device of the second device, the above preset The standard communication protocol is directly used as the target charging protocol.

Optionally, after receiving the charging protocol information sent by the first device, the second device may determine one of the charging protocols supported by both the first device and the second device as the target charging protocol, that is, the second device may start from One charging protocol among the at least two charging protocols supported by the first device and the same plurality of charging protocols supported by the second device is determined as the target charging protocol. Alternatively, the second device may determine multiple charging protocols supported by both the first device and the second device, and then select one of the charging protocols as the target charging protocol according to some selection mechanisms. For example, the second device may The priority sequence of the charging protocol determines the target charging protocol, or the second device may determine the target charging protocol according to the rated power of the commonly supported charging protocols, and so on. Optionally, as an implementable manner, if both the second device and the first device support two or more charging protocols, the second device includes the two or more charging protocols, The charging protocol with the highest priority is determined as the target charging protocol. Alternatively, if the charging protocols supported by both the second device and the first device include two or more, the second device determines the charging protocol with the highest charging power among the two or more charging protocols as the target charging protocol. protocol; further, if the charging protocol supported by both the second device and the first device includes the first candidate protocol and the second candidate protocol, and the charging power of the second candidate protocol is greater than the charging power of the first candidate protocol and the preset power The second device may determine the second candidate protocol as the target charging protocol. Alternatively, if both the second device and the first device support two or more charging protocols, the second device may determine the third candidate charging protocol with the highest priority among the two or more charging protocols is the target charging protocol; wherein, the third candidate charging protocol is a preset number of charging protocols determined from the above two or more than two charging protocols in descending order of charging power. Alternatively, if both the second device and the first device support two or more charging protocols, the second device may determine the fourth candidate charging protocol with the highest charging power among the above two or more charging protocols as The target charging protocol; wherein, the fourth candidate charging protocol is a preset number of charging protocols determined from the above two or more charging protocols in descending order of priority.

After the first device receives the identification of the target charging protocol, the first device performs a charging process with the second device based on the target charging protocol. For example, if the first device is a power supply device and the second device is a charging device, the first device charges the second device according to the target charging protocol; if the first device is a charging device and the second device is a power supply device, the second device The first device is charged according to the target charging protocol.

In this embodiment, when both the first device and the second device support multiple charging protocols, the first device sends charging protocol information to the second device, since the charging protocol information includes at least two charging protocols supported by the first device. The identification of a charging protocol is equivalent to the first device sending multiple charging protocols to the second device at one time, and the second device can directly determine the target charging protocol based on the multiple charging protocols supported by the first device and the charging protocols supported by itself , avoiding the process of selecting the charging protocol multiple times, thereby shortening the time for the second charging device to select the charging protocol, and reducing the interaction time between the first device and the second device before charging.

In the scenario where the first device sends the charging protocol information to the second device, a communication connection needs to be established in advance between the first device and the second device. In one embodiment, the above method further includes: A communication protocol, establishing a communication connection with the second device.

Wherein, the preset standard communication protocol may be a communication protocol supported by both the first device and the second device, or may be a charging protocol supported by both the first device and the second device. Optionally, the first device may send a handshake request to the second device, and after receiving the handshake request from the first device, the second device sends a response message to the first device to establish a communication connection with the second device. It may also be that the second device sends a handshake request to the first device, and after receiving the handshake request sent by the second device, the first device sends a response message to the second device to establish a communication connection with the first device. Optionally, the above-mentioned target charging protocol may be the preset standard communication protocol. It can be understood that the first device and the second device can communicate based on a preset standard communication protocol. If the standard communication protocol supports the communication between the first device and the charging device of the second device, the above target charging protocol can be Directly as the preset standard communication protocol.
