Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

In the related art, along with the development of technology, various electronic products are upgraded, the power consumption of the products is greatly improved under the continuous enhancement of the performance of the products, various quick-charging technologies are not deducted under the condition, and high-power chargers are continuously updated. The charger is an inherent protocol before once being manufactured, and only the replacement chip (IC) is disassembled to upgrade and update or the serial port is disassembled to upgrade and update the program, so that users only purchase new chargers continuously, and a great deal of energy waste is caused. And the old chargers are largely discarded, so that serious environmental pollution is caused.

For example, for a 240W charger, i.e. the output power can reach 240W at maximum, the proposed scheme is that the single-port outputs 48V/5A and 240W, but since the update of the fast charging protocol is not reached temporarily at that time, the power needs to be realized through multiple ports, and as the fast charging protocol is updated, the charging product is updated, and the inherent protocol of the charger cannot be updated synchronously, the charging power of the charging product will be limited, which affects the use of the user, and the user will change a new charger. If the charger is to be synchronously upgraded, the charging protocol is sent back to the manufacturer to be disassembled and upgraded for assembly, and the cost is greatly increased.

Based on the first instruction, in the embodiment of the application, the terminal receives a first instruction sent by the charging equipment; the first instruction is used for indicating the terminal to establish connection with the charging equipment; after the terminal establishes connection with the charging equipment, receiving first information sent by the charging equipment; the first information is used for downloading an upgrade data packet by the terminal; downloading the upgrade data packet by using the first information; and sending the upgrade data packet to the charging equipment so as to update a charging protocol by the charging equipment.

Fig. 1 is a schematic implementation flow chart of a protocol upgrading method of the embodiment of the present application, which is applied to a terminal, as shown in fig. 1, and the method includes steps 101 to 104:

step 101: receiving a first instruction sent by charging equipment; the first instruction is used for indicating the terminal to establish connection with the charging equipment.

It is understood that the connection establishment may refer to the establishment of a wired connection or a wireless connection; wherein the wireless connection includes bluetooth connection, wiFi connection, etc.

It is understood that the charging device may refer to a charger for charging the terminal.

It is understood that the terminals include mobile terminals and the like.

It will be appreciated that the terminal may establish a connection with at least one charging device.

Step 102: after the terminal establishes connection with the charging equipment, receiving first information sent by the charging equipment; the first information is used for downloading an upgrade data packet by the terminal.

It will be appreciated that the terminal may download the upgrade data package from a server.

It is understood that the first information may specifically refer to identification information of the charging device, such as a model number.

It will be appreciated that, in order to ensure the security of the interaction between the terminal, the charging device and the server, the charging device sends the first information to the server via the terminal before the transmission of the upgrade data packet between the terminal, the charging device and the server is started. The server authenticates the charging equipment by using the first information, and after the charging equipment passes the authentication of the server, the terminal can download the upgrade data packet from the server.

For example, the first information carries model information of the charging device, after the server receives the first information, the server searches the model from the local database, and if the model is found from the local database, the charging device passes the authentication of the server, so that the terminal can download the upgrade data packet from the server.

Step 103: and downloading the upgrade data packet by using the first information.

In view of the fact that in practical application, some charging devices are preconfigured with the remaining output power and some charging devices are not preconfigured with the remaining output power because of factors such as volume, cost and the like of the devices, when the terminal downloads the upgrade data packet from the server, the server can first judge whether the charging devices are preconfigured with the remaining output power. In addition, in order to realize autonomous control of charging by a user, when the server determines that the charging device is preconfigured with residual output power, the server may also select an upgrade data packet required by the user according to information provided by the user, and send the upgrade data packet to the terminal, where the upgrade data packet is sent to the charging device by the terminal.

Based on this, in some embodiments, the downloading the upgrade data packet using the first information includes:

transmitting the first information to a server for the server to determine whether the charging device is preconfigured with residual output power;

receiving second information sent by the server under the condition that the server determines that the charging equipment is preconfigured with residual output power; the second information is used for a user using the terminal to determine whether to update a charging protocol for the charging equipment;

transmitting third information to the server if the user determines to update a charging protocol for the charging device; the third information is used for the server to download an upgrade data packet corresponding to the charging equipment;

and receiving the upgrade data packet sent by the server.

It is understood that the remaining output power may refer to a difference between the maximum output power of the charging device and the current output power. For example, assuming that the maximum output power of the charging device is 240W and the current output power is 200W, the remaining output power is 240W to 200 w=40w.

It will be appreciated that the remaining output power may also be referred to as margin. For example, the charging power before the charging device upgrades the charging protocol is 64W, the pre-configured margin may be 150W, and then the charging power of 240W may be supported after upgrading the charging protocol.

For example, the first information may carry identification information of the charging device, such as a model number of the charging device. After the server receives the first information, searching the residual output power corresponding to the model from a preset database, and if the residual output power corresponding to the model is found from the preset database, determining that the charging equipment is preconfigured with the residual output power; and if the residual output power corresponding to the model is not found out from the preset database, determining that the charging equipment is not preconfigured with the residual output power.

It may be understood that the second information may carry information about an upgradeable charging protocol corresponding to the charging device, so that, according to the second information, a user using the terminal may determine whether to update the charging protocol for the current charging device, and in the case that it is determined to update the charging protocol for the current charging device, the user may also select information about a charging protocol required by the user, such as version information, and send the information as third information to the server, where the server determines, according to information about the charging protocol required by the user, an upgrade data packet corresponding to the charging device.

For example, the information related to the upgradeable charging protocol corresponding to the charging device includes multiple versions of the charging protocol, such as charging protocol version 1 and charging protocol version 2, if the charging protocol required by the user is charging protocol version 2, it is determined that the user needs to update the charging protocol of the current charging device, and an upgrade data packet corresponding to charging protocol version 2 is selected and sent to the terminal. If the charging protocol required by the user is charging protocol version 3, it is determined that the user does not need to update the charging protocol for the current charging device.

In consideration of the fact that in practical application, the terminal can establish connection with a plurality of charging devices at the same time, so that in order to enable the plurality of charging devices to update a charging protocol by utilizing respective upgrading program packages, the problem that upgrading failure caused by the fact that a certain charging device uses upgrading data packages of other charging devices is avoided, the terminal can send relevant information for verification to the charging devices before sending the upgrading data packages to the charging devices, and after the charging devices pass verification, the charging protocol is updated by utilizing the upgrading data packages corresponding to the terminal.

Based on this, in some embodiments, the receiving the upgrade data packet sent by the server includes:

receiving fourth information sent by the server, and sending the fourth information to the charging equipment; the fourth information is used for checking the charging equipment;

receiving a verification result sent by the charging equipment;

downloading the upgrade data packet from the server under the condition that the verification result represents that the charging equipment passes the verification;

and sending the upgrade data packet to the charging equipment.

It can be understood that the fourth information may carry an SN code of the charging device, so that the charging device compares the received SN code with an SN code stored in the charging device, and indicates that the charging device passes the verification when the comparison result indicates that the received SN code is identical to the SN code stored in the charging device.

Step 104: and sending the upgrade data packet to the charging equipment so as to update a charging protocol by the charging equipment.

It can be appreciated that the updated charging protocol is used to charge the terminal, so as to meet the requirement of the user on the charging power.

It is understood that the charging protocol may refer to a rule, convention.

It is understood that the charging protocol may specifically refer to a fast charging protocol, such as USB PD protocol, AFC, FCP protocol, etc.

In consideration of practical application, the charging power of the charging device required by the user may be large, so if the remaining output power of the charging device cannot meet the charging power of the charging device currently required by the user, the user may be prompted that the charging protocol cannot be updated for the current charging device.

Based on this, in some embodiments, the method further comprises:

receiving fifth information sent by the charging equipment under the condition that the charging equipment detects that the self residual output power is smaller than or equal to a preset threshold value; the fifth information is used for prompting that a user using the terminal cannot update the charging protocol of the charging equipment.

Step 202: after the terminal establishes connection with the charging equipment, first information is sent to the terminal; the first information is used for downloading an upgrade data packet by the terminal.

It will be appreciated that the terminal may download the upgrade data package from a server.

It will be appreciated that, in order to ensure the security of the interaction between the terminal, the charging device and the server, the charging device sends the first information to the server via the terminal before the transmission of the upgrade data packet between the terminal, the charging device and the server is started. The server authenticates the charging equipment by using the first information, and after the charging equipment passes the authentication of the server, the terminal can download the upgrade data packet from the server.

For example, the first information carries model information of the charging device, after the server receives the first information, the server searches the model from the local database, and if the model is found from the local database, the charging device passes the authentication of the server, so that the terminal can download the upgrade data packet from the server.

Step 203: and receiving the upgrade data packet sent by the terminal.

In view of the fact that in practical application, some charging devices are preconfigured with the remaining output power and some charging devices are not preconfigured with the remaining output power because of factors such as volume, cost and the like of the devices, when the terminal downloads the upgrade data packet from the server, the server can first judge whether the charging devices are preconfigured with the remaining output power. In addition, in order to realize autonomous control of charging by a user, when the server determines that the charging device is preconfigured with residual output power, the server may also select an upgrade data packet required by the user according to information provided by the user, and send the upgrade data packet to the terminal, where the upgrade data packet is sent to the charging device by the terminal.

Based on this, in some embodiments, the receiving the upgrade data packet sent by the terminal includes:

For example, assuming that the maximum output power of the charging device is 240W and the current output power is 200W, the remaining output power is 240W to 200 w=40w.

It will be appreciated that the remaining output power may also be referred to as margin.

For example, the first information may carry model information of the charging device, after the server receives the first information, the server searches for remaining output power corresponding to the model from a preset database, and if the remaining output power corresponding to the model is found from the preset database, determines that the charging device is preconfigured with remaining output power; and if the residual output power corresponding to the model is not found out from the preset database, determining that the charging equipment is not preconfigured with the residual output power.
