Charging device, system thereof and charging method

Abstract

The invention is suitable for the field of charging technology. The invention discloses a charging device. The charging device comprises a charging controller which is electrically connected with a charging power acquiring end, and a connector which is connected with a charging output end that is in signal connection with the charging controller. The charging controller comprises a microprocessor,and a switch circuit which is connected with the control output of the microprocessor and controls charging output. The switch circuit controls charging on-and-off between the power acquiring end andthe connector by the signal which is output from the microprocessor. The microprocessor is provided with a solid identifying code which is composed of a plurality of sets of identifying codes. When the identifying code which is read by the microprocessor through the reader matches a random set of verifying code in the solid identifying code, an on control signal is output to the switch circuit, and the connector and the charging power acquiring end form a charging loop. Because the charging device can automatically read the identifying code for charging through controlling in connection witha mobile phone, carrying or purchasing of a charger by a user for charging is prevented, and purchasing cost of the user or low convenience in carrying is reduced. Furthermore the charging device realizes simple operation and improves user experience.

Description

Technical field [0001] The invention relates to the technical field of charging portable equipment, in particular to a charging device, a system and a charging method. Background technique [0002] As mobile terminals, such as mobile phones, have gradually become essential products for people’s daily lives, mobile phones are usually limited in size for easy carrying and use, making their own batteries limited. The characteristics of frequent use of mobile phones are prone to insufficient battery life. Therefore, it is necessary to replenish the electric energy in time, and people usually forget to carry the charger if they do not bring it because it is inconvenient to carry when going out, which is likely to cause the inability to charge. [0003] Then there is a charger that can be set with a password. The user scans the QR code on the product through the APP software pre-installed on the phone before using it, obtains a set of passwords from the APP software server, and enters th...

AI Technical Summary

Problems solved by technology

Although the charger is charged after obtaining the password through scanning, it can manage the use of the charger, but the user needs to manually enter the password when using it. On the one hand, a password input button needs to be set on the product, and on the other hand, the complexity of the user operation is increased. , poor user experience
