[0056] The embodiment of the present application provides a charging device and a charging method thereof, and a storage medium. By embedding a charging protocol in a control chip of the charging device and setting a charging protection structure that meets the requirements of fast charging, the miniaturization and low-cost design of the external terminal are achieved, and the external terminal is made more environmentally friendly.

[0057] There are usually two types of chargers on the market. One is a conventional charger, which charges the external terminal through a conventional charging interface. The charging speed is slow. For consumers who are not in a hurry to charge, this charger is inexpensive. The other is a fast charger, which charges the external terminal through a fast charging interface. The charging speed is fast and can meet the needs of consumers who are in a hurry to charge.

[0058] The charging device provided in the embodiment of the present application integrates a charging protection structure that can be used for fast charging and a fast charging protocol into one charging device, so that the structural design of the external terminal that needs to be fast charged is more miniaturized and the production cost of the external terminal can be reduced.

[0059] Please refer to the following Figure 1 The charging device 100 shown in the embodiment of the present application includes a control chip 101, a charging structure 102, a charging protection structure 103 and a charging interface 104.

The charging protection structure 103 is electrically connected to the charging structure 102 and the charging interface 103 respectively.

[0060] The charging interface 104 is used to receive fast charging request information sent by the external terminal 200;

[0061] The control chip 101 is used to receive the fast charging request information sent by the charging interface 104, and determine whether the fast charging request information matches the fast charging protocol. After determining that the fast charging request information matches the fast charging protocol, the control chip 101 sends a fast charging instruction to the charging structure 102 and sends a fast charging response information to the charging interface 104;

[0062] The charging structure 102 is used to transmit a fast charging voltage to the charging protection structure 103 according to a fast charging instruction;

[0063] The charging protection structure 103 is used to transmit the fast charging voltage to the charging interface 104;

[0064] The charging interface 104 is further configured to output the received fast charging response information and the fast charging voltage to the external terminal 200 .

[0065] It should be noted that the external terminal 200 may be an electronic cigarette, a medical electronic atomization device, an earphone or a mobile phone, which is not specifically limited here.

[0066] An embodiment of the present application provides a charging device 100, which includes a control chip 101, a charging structure 102, a charging protection structure 103 and a charging interface 104. The control chip 101 of the charging device 100 is embedded with a fast charging protocol. The control chip 101 first determines whether the fast charging request information matches the fast charging protocol based on the received fast charging request information. After determining that the fast charging request information matches the fast charging protocol, the control chip 101 sends a fast charging instruction to the charging structure 102 and sends a fast charging response information to the charging interface 104.

[0135] After receiving the normal charging instruction, the charging interface 102 may switch on its own normal charging circuit 1032 according to the normal charging instruction, and transmit a normal charging voltage to the normal charging circuit 1032 of the charging protection structure 103 .

[0136] 562. The charging protection structure transmits the conventional charging voltage to the charging interface through its own conventional charging protection circuit;

[0137] The charging protection structure 103 may transmit the transmitted normal charging voltage to the charging interface 104 through its own normal charging protection circuit 1032 .

[0139] After receiving the normal charging response information sent by the control chip 101 , the charging interface 104 may output the normal charging response information to the external terminal 200 , and notify the external terminal 200 that it is ready to perform normal charging on the external terminal 200 .

[0141] After receiving the normal charging voltage transmitted by the normal charging protection circuit 1032 , the charging interface 104 finally outputs the normal charging voltage to the external terminal 200 .

[0142] It should be noted that there is no order in which step 572 and step 582 are executed. Step 572 may be executed first and then step 582, or step 582 may be executed first and then step 572, or step 572 and step 582 may be executed simultaneously. The specific order is not limited here.

[0144] In this embodiment, since a circuit structure capable of outputting a fast charging voltage and a regular charging voltage is provided in the charging device 100, when the control chip 101 receives different charging information, it can send different charging instructions, namely, fast charging instructions or regular charging instructions, to the corresponding charging circuit according to different charging request information, namely, fast charging request information or regular charging request information. When a fast charging instruction is sent, the fast charging circuit 1031 in the charging structure 102 will be turned on, and the fast charging voltage will be output to the fast charging protection circuit 1031 of the charging protection structure 103. When a regular charging instruction is sent, the regular charging circuit 1032 in the charging structure 102 will be turned on, and the regular charging voltage will be output to the regular charging protection circuit 1032 of the charging protection structure 103. Finally, the charging voltage is transmitted to the external terminal 200 through the charging interface 104, so that the external terminal 200 is fast charged or normally charged according to the corresponding charging request information of the external terminal 200.

[0145] As can be seen from the above, by setting two different charging circuit structures in the charging device 100 and embedding the fast charging protocol in the control chip 101 of the charging device 100, different charging modes can be switched to charge the external terminal 200 according to different charging request information of the external terminal 200. In this way, the external terminal 200 can save the cost of setting up a charging structure, thereby not only realizing the miniaturization and low cost of the structure of the external terminal 200, but also making the charging method of the charging device 100 flexible and diverse, and freely switching the charging mode according to the needs of consumers, thereby improving the use performance of the charging device 100, enriching the charging mode of the charging device 100, and meeting the diverse use needs of consumers at the same time, making the use of the charging device 100 more convenient.
