Fig. 2 is a flow chart illustrating a power supply method of some embodiments of the present application. In order to solve the problem that the communication protocols of the power supply equipment and the equipment to be charged are not matched, the embodiment of the application discloses a power supply method, which is executed by the power supply equipment and is used for realizing communication and power supply of the equipment to be charged with different equipment models. Specifically, as shown in fig. 2, the power supply method includes the following steps:

s210, the power supply equipment obtains the equipment model of the equipment to be charged connected with the power supply equipment.

Here, the communication protocols used by the devices to be charged of different device models may be different. As the devices to be charged are updated, the communication protocol used may change. Generally, the device model of the device to be charged and the communication protocol used by the device to be charged have a corresponding relationship, and the corresponding relationship is that the device to be charged is already matched when leaving the factory, and will not be changed after leaving the factory.

Before this step is performed, the power supply method should further include the step of connecting the device to be charged to the power supply device. The power supply device can then obtain the device model of the device to be charged connected to it.

S220, the power supply equipment sends the equipment model of the equipment to be charged to a cloud server.

Here, the power supply device may send the device model of the device to be charged to the cloud server in a wired or wireless manner. After receiving the device model of the device to be charged, the cloud server searches a communication protocol matched with the current device model according to the corresponding relation between the device model and the communication protocol.

The correspondence between the device model and the communication protocol is stored in the cloud server in advance, and the correspondence is increased with the increase of new devices to be charged.

Here, the cloud server may store, in addition to the correspondence between the device model and the communication protocol, other data of the device to be charged and the power supply device, such as charging requirement information of the device to be charged, charging state information during charging, power supply information of the power supply device, identity information of the power supply device, and location information of the power supply device.

S230, the power supply equipment receives a communication protocol which is sent by the cloud server and matched with the equipment model of the equipment to be charged.

The cloud server searches a communication protocol matched with the equipment model of the current equipment to be charged according to the corresponding relation between the equipment model and the communication protocol, and then sends the searched communication protocol to the power supply equipment. The power supply equipment receives a communication protocol matched with the equipment model of the current equipment to be charged through a communication link between the power supply equipment and the cloud server.

Here, the power supply device can communicate and charge the device to be charged using a plurality of different communication protocols instead of using only the communication protocol determined when the power supply device is shipped from the factory. Therefore, the power supply device needs to receive a communication protocol which is sent by the cloud server and matches with the device model of the device to be charged.

And S240, the power supply equipment performs charging control on the equipment to be charged based on the communication protocol.

Here, the charging process of the power supply apparatus for the apparatus to be charged is realized based on a communication protocol that is capable of not only transmitting information similar to the charging demand, the charging state, and the like to the power supply apparatus and the apparatus to be charged but also controlling the start and end of the charging process. Therefore, the charging process and the communication process between the power supply apparatus and the apparatus to be charged are controlled based on the communication protocol.

Based on the technical scheme, when the devices to be charged are different, the remote server can search the corresponding communication protocol according to the device models of the devices to be charged and send the communication protocol to the power supply device, the devices to be charged and the power supply device control the charging process based on the communication rule, and the same power supply device charges the devices to be charged with different models, so that the power supply cost is effectively reduced, the resources are saved, and great convenience is brought to the charging of the devices to be charged.

It should be noted that, in this embodiment, the power supply device sends the device model of the device to be charged to the cloud server, and certainly, the device model of the device to be charged may also be sent to the cloud server in other manners, for example, the device to be charged may send its own device model to the cloud server. Meanwhile, the to-be-charged device needs to send the identity of the power supply device connected with the to-be-charged device to the cloud server, and the cloud server can send the communication protocol matched with the device model of the to-be-charged device to the power supply device connected with the to-be-charged device according to the identity.

It should be noted that the correspondence between the device model of the device to be charged and the communication protocol is stored in the cloud server, and the cloud server finds the communication protocol matching the device model of the current device to be charged according to the correspondence between the device model of the device to be charged and the communication protocol. In actual operation, the corresponding relationship between the device model of the device to be charged and the communication protocol may also be stored in the power supply device, and after the power supply device acquires the device model of the device to be charged, the power supply device searches for the communication protocol matching the device model of the current device to be charged according to the corresponding relationship between the stored device model and the communication protocol. Of course, in actual operation, the communication protocol matching the device model of the current device to be charged may also be sent to the power supply device by the device to be charged itself.

In another embodiment, as shown in fig. 3, the power supply method includes the steps of:

and S310, the power supply equipment acquires the equipment model of the equipment to be charged connected with the power supply equipment.

And S320, the power supply equipment sends the equipment model of the equipment to be charged to a cloud server.

S330, the power supply equipment receives a communication protocol which is sent by the cloud server and matched with the equipment model of the equipment to be charged.

And S340, the power supply equipment receives charging readiness information sent by the equipment to be charged based on the communication protocol.

Here, when the device to be charged has a condition for receiving the charging power of the power supply device, the device to be charged generates information on readiness for charging, and transmits the information on readiness for charging to the power supply device based on a communication protocol for communicating with the power supply device.

The condition for accepting the charging power of the power supply device may include that the charging circuit on the side of the device to be charged is closed, the power supply information of the power supply device matches the power demand information of the device to be charged, the communication protocol used by the power supply device matches the communication protocol used by the device to be charged, and the like.

The power supply information of the power supply apparatus may include: power supply equipment supply voltage, power supply equipment supply current, and the like. The power demand information includes a voltage demand of the device to be charged, a current demand of the device to be charged, a charging mode demand, and the like. The charging mode includes constant voltage charging and constant current charging.

Here, since the power supply apparatus uses a communication protocol that matches the apparatus model of the apparatus to be charged, when the apparatus to be charged sends information of readiness for charging to the power supply apparatus based on its communication protocol, in most cases, the power supply apparatus receives the information of readiness for charging, which effectively improves the information reaching rate between the power supply apparatus and the apparatus to be charged. Only when a serious abnormality occurs, the power supply apparatus may not receive the information of readiness for charging, for example, a physical link between the power supply apparatus and the apparatus to be charged is disconnected.

In order to ensure the reaching rate of the information, an information feedback mechanism can be added, that is, when the power supply equipment receives the information of the charging readiness sent by the equipment to be charged, a response message corresponding to the information of the charging readiness is fed back to the equipment to be charged, after the equipment to be charged receives the response message, the equipment to be charged determines that the power supply equipment has received the information of the charging readiness, if the equipment to be charged does not receive the response message within a preset time period, the equipment to be charged sends the information of the charging readiness to the power supply equipment again until the equipment to be charged receives the response message of the information of the charging readiness. The information feedback mechanism can effectively improve the information touch rate between the power supply equipment and the equipment to be charged, so that the safety and effectiveness in the charging process can be improved.

And S350, the power supply equipment closes a circuit for charging the equipment to be charged based on the information of the charging readiness.

Here, after receiving the information of readiness for charging sent by the device to be charged, the power supply device confirms that the device to be charged is ready to receive charging power, and can receive charging power from the power supply device. At this time, the power supply device closes the power supply circuit on the power supply device side, the circuit between the power supply device and the device to be charged is switched on, and the power supply device starts to charge the device to be charged.

In addition, after the physical connection between the power supply device and the device to be charged is completed, if the power supply device does not receive the information of readiness for charging sent by the device to be charged in a long time period, the power supply device may send predetermined early warning information to the cloud server and/or the device to be charged to prompt the cloud server and/or the device to be charged to perform corresponding fault detection, and may also send a prompt to the device to be charged to start charging as soon as possible.

In this embodiment, the power supply device realizes charging of the device to be charged by using a communication protocol matched with the device model of the device to be charged. The process of starting charging is not realized by only connecting a circuit between the power supply equipment and the equipment to be charged, the conditions of charging power of the equipment to be charged and receiving the power supply equipment need to be met before charging is started, and the matching process of the conditions depends on the communication protocol for communication between the power supply equipment and the equipment to be charged. It can be seen that the communication protocol plays a crucial role in ensuring the safety and effectiveness of the charging process.

In addition, in order to ensure the safety of the charging process, the device to be charged sends information of charging readiness to the power supply device, and after the power supply device closes the power supply circuit on the side of the power supply device, the power supply device needs to send a charging control instruction for starting charging to the device to be charged based on a communication protocol matched with the device model of the device to be charged, and after receiving the charging control instruction for starting charging, the device to be charged starts to receive charging electric energy from the power supply device.

In another embodiment, as shown in fig. 4, the power supply method includes the steps of:

and S410, the power supply equipment acquires the equipment model of the equipment to be charged connected with the power supply equipment.

And S420, the power supply equipment sends the equipment model of the equipment to be charged to a cloud server.

S430, the power supply equipment receives a communication protocol which is sent by the cloud server and matched with the equipment model of the equipment to be charged.

And S440, the power supply equipment receives the information of ending charging, which is sent by the equipment to be charged based on the communication protocol.

Here, the device to be charged generates information for ending charging after charging is completed, and transmits the information for ending charging to the power supply device based on a communication protocol for communicating with the power supply device.

The charging completion of the device to be charged may refer to that the battery of the device to be charged is fully charged or that the amount of electricity in the battery of the device to be charged reaches a predetermined amount of electricity.

Here, since the power supply device uses a communication protocol that matches the device model of the device to be charged, when the device to be charged transmits information to the power supply device to end charging based on the communication protocol, in most cases, the power supply device receives the information to end charging, which effectively improves the information reaching rate between the power supply device and the device to be charged. Only when a serious abnormality occurs, the power supply device may not receive the information of ending the charging, for example, a physical link between the power supply device and the device to be charged is disconnected.

In order to ensure the reaching rate of the information, an information feedback mechanism can be added, that is, when the power supply equipment receives the information of finishing charging sent by the equipment to be charged, the power supply equipment feeds back a response message corresponding to the information of finishing charging to the equipment to be charged, after the equipment to be charged receives the response message, the equipment to be charged determines that the power supply equipment has received the information of finishing charging, and if the equipment to be charged does not receive the response message within a preset time period, the equipment to be charged sends the information of finishing charging to the power supply equipment again until the equipment to be charged receives the response message of the information of finishing charging. The information feedback mechanism can effectively ensure the information touch rate between the power supply equipment and the equipment to be charged, thereby improving the safety and effectiveness in the charging process.

And S450, the power supply equipment disconnects a circuit for charging the equipment to be charged based on the information for finishing charging.

Here, after the power supply device receives the information of ending charging sent by the device to be charged, it is confirmed that the charging of the device to be charged is completed, and the supply of charging electric energy to the device to be charged can be stopped. At this time, the power supply device disconnects the power supply circuit on the power supply device side, the circuit between the power supply device and the device to be charged is disconnected, and the power supply device stops charging the device to be charged.

In this embodiment, the charging of the to-be-charged device by the power supply device is realized by using a communication protocol matched with the device model of the to-be-charged device. The charging stopping process can be realized by not only disconnecting the circuit between the power supply equipment and the equipment to be charged, but also sending information of ending charging to the power supply equipment before disconnecting the charging circuit, and the power supply circuit on the side of the power supply equipment cannot be automatically disconnected without the information of ending charging. In addition, before the charging process is finished, other information interaction, such as charging amount information, may also need to be performed between the power supply device and the device to be charged. The interaction process of such information depends on the communication protocol for communication between the power supply device and the device to be charged. It can be seen that the communication protocol plays a crucial role in ensuring the safety and effectiveness of the charging process.

The power supply equipment periodically collects the data and transmits the data to the cloud server. And the cloud server corrects the received data and stores the corrected data. In addition, the power supply equipment transmits the acquired data to the equipment to be charged at the same time, and the equipment to be charged can compare and verify the received data with the acquired data of the equipment to be charged, so that disputes caused by bill differences and the like are reduced, and the probability of successful one-time charging of the equipment to be charged is improved.

Specifically, if the acquired data is abnormal, the cloud-end controller or the device to be charged can give an alarm, and corresponding measures are taken according to the specific abnormal conditions of the data, so that the safety of the charging process is ensured. For example, if the current output voltage of the power supply device exceeds the maximum allowable output voltage, after receiving the output voltage, the cloud server or the device to be charged may alarm according to the maximum allowable output voltage, and disconnect the charging circuit between the power supply device and the device to be charged. For another example, if the current temperature of the power supply device exceeds the maximum allowable temperature, after receiving the temperature of the power supply device, the cloud server or the device to be charged may alarm according to the maximum allowable temperature, and disconnect the charging circuit between the power supply device and the device to be charged.
