In the present embodiment, each charging interface 110 is configured to couple with a power supply 210 of a type matching with the charging interface 110, so as to obtain power of the power supply 210 matching with its own type. Each charging interface 110 is coupled to an input terminal of the main control device 150, so that each charging interface 110 can output the acquired electric energy to the main control device 150.
The battery module 120 is a rechargeable power supply 210, and the battery module 120 is coupled to the output end of the main control device 150, so that the battery module 120 can charge and store energy for itself by acquiring the output voltage of the main control device 150.

And the battery module 120 is coupled to the main control device 150, so that the battery module 120 can transmit its own status information to the main control device 150. Wherein the state information includes: battery voltage information and battery power information.
By one approach, the battery module 120 includes: at least one lithium battery. When there is one lithium battery, the positive terminal of the lithium battery is coupled to the output terminal and the output terminal of the main control device 150, and the negative terminal of the lithium battery is grounded to form a loop. When there are a plurality of lithium batteries, the positive terminals of the lithium batteries are coupled to the negative terminals of the adjacent lithium batteries, and the positive terminal of the first lithium battery is coupled to the output terminal and the output terminal of the main control device 150, respectively. And the negative terminal of the last lithium battery is grounded to form a loop.
By coupling the input end of the temperature detection module 130 with the battery module 120, the temperature detection module 130 can obtain the operating temperature of the battery module 120, generate temperature information according to the operating temperature, and output the temperature information to the main control device 150. As one mode, the temperature detecting module 130 is provided with a thermistor, the resistance of the thermistor linearly changes with the temperature, and the resistance of the thermistor also changes correspondingly due to the change of the operating temperature of the battery module 120, so as to generate an electric signal. It will be appreciated that the electrical signal generated may be a temperature signal. Through the coupling between the output end of the temperature detection module 130 and the main control device 150, the temperature detection module 130 outputs the generated temperature signal to the main control device 150, so that the main control device 150 obtains the operating temperature of the battery module 120.
The key module 140 is configured to obtain a control instruction input by a user, and output the control instruction to the main control device 150. In this embodiment, the key module 140 may be an integrated circuit provided with keys, or may be a touch panel with virtual keys. When a user presses a key or a touch pad, the movement of the key or the conduction of a contact on the touch pad enables the coupling of control areas in the integrated circuit. The control regions of the integrated circuit are coupled to form a loop to generate an electrical signal. Through the coupling of the key module 140 with the main control device 150, the key module 140 can output the generated electrical signal to the main control device 150. It is also understood that the electrical signal generated by the key module 140 may represent a control command input by a user.
Referring to fig. 3, the master control device 150 includes: the device comprises a main control module and a voltage adapting module. In this embodiment, the main control module is an integrated circuit chip and has signal processing capability. The integrated circuit chip may be a general-purpose Processor, including a Central Processing Unit (CPU), a Network Processor (NP), and the like; but also Digital Signal Processors (DSPs), Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs) or other Programmable logic devices, discrete gate or transistor logic devices, discrete hardware components. The various methods, steps and logic blocks disclosed in the embodiments of the present invention may be implemented or performed. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.
Specifically, each charging interface 110 is coupled to the main control module, and after the charging interfaces 110 are coupled to the matched power supply 210 through the connection line, the main control module can form data interaction with the power supply 210. When the power supply 210 is an unregulated power supply, the main control module can obtain the output voltage of the power supply 210 through data interaction, and the output voltage is also the maximum output voltage. When the power supply 210 is an adjustable power supply, the main control module can control and adjust the output voltage of the power supply 210 through data interaction, so that the power supply 210 outputs the maximum output voltage to the charging interface 110 coupled to the power supply 210.
As one approach, the voltage adaptation module is coupled with the master control module. The master control module is also capable of detecting the maximum output voltage of each charging interface 110 coupled to the matching power supply 210. After the plurality of charging interfaces 110 are coupled to the matched power supply 210, if the maximum output voltage of each charging interface 110 is the same, the main control module can generate a coupling instruction to the voltage adaptation module to control the voltage adaptation module to be coupled to each charging interface 110, so that the voltage adaptation module obtains an input voltage which is not greater than the sum of the plurality of maximum output voltages of the preset input voltage threshold. If the maximum output voltages of the charging interfaces 110 are different, the main control module can also generate a coupling instruction to the voltage adaptation module to control the voltage adaptation module to be coupled with the charging interfaces 110 with the maximum output voltages. If some maximum input voltages in the charging interfaces 110 are the same and some maximum input voltages are different, the main control module respectively obtains a voltage sum of the multiple maximum input voltages with the same value and obtains a maximum value of the different maximum input voltages, and then the main control module compares the voltage sum with the maximum value. When the voltage sum is greater than or equal to the maximum value, the main control module can generate a coupling instruction to the voltage adaptation module to control the voltage adaptation module to be coupled with the charging interfaces 110 with the same maximum input voltage, so that the voltage adaptation module obtains an input voltage which is not greater than the sum of a plurality of maximum output voltages of a preset input voltage threshold. And when the voltage sum is smaller than the maximum value, the main control module can also generate a coupling instruction to the voltage adaptation module to control the voltage adaptation module to be coupled with the charging interface 110 with the maximum value in different maximum input voltages. And the main control module can also generate an adjusting instruction to the voltage adaptation module according to the input voltage obtained by the coupled maximum input voltage, so that the voltage adaptation module can output the output voltage with the same value as the input voltage.
Furthermore, the main control module is coupled to the output end of the temperature detection module 130, so that the main control module can obtain the temperature information sent by the temperature detection module 130, and compare the temperature information with the preset temperature information. When the temperature information is higher than the preset temperature information, the main control module generates an adjustment instruction to the voltage adaptation module, so that the voltage adaptation module reduces the output voltage output to the battery module 120. And the main control module compares the temperature information obtained again with the preset temperature information according to the preset time after the preset time is compared between the temperature information and the preset temperature information. When the temperature information is still greater than the preset temperature information, the main control module generates the adjustment instruction again to the voltage adaptation module, so that the voltage adaptation module stops outputting the output voltage to the battery module 120.
Meanwhile, through the coupling of the main control module with the key module 140 and the battery module 120, the main control device 150 can also obtain the control instruction sent by the key module 140 and the status information sent by the battery module 120, and package the temperature information and the status information according to the control instruction to generate the display information to the indication module 160.
In this embodiment, the voltage adaptation module may also be an integrated circuit chip, and the voltage adaptation module can have protection functions such as overvoltage, overcurrent, short circuit, reverse connection and the like through its own circuit structure. By one approach, the input voltage adaptation range of the voltage adaptation module is 3.6 volts to 20 volts. Wherein 20 volts is a predetermined input voltage threshold. Through the coupling of the voltage adaptation module and the main control module, the voltage adaptation module can acquire a coupling instruction sent by the main control module, and after the coupling instruction is analyzed and driven to be amplified, the voltage adaptation module can control the voltage adaptation module to be coupled with one or more of the plurality of charging interfaces 110 corresponding to the coupling instruction, so that the voltage adaptation module can acquire the input voltage smaller than or equal to the preset input voltage threshold. The voltage adaptation module can acquire the adjustment command sent by the main control module, and also analyze and drive and amplify the adjustment command, so that the voltage adaptation module can output the output voltage with the same value as the input voltage to rapidly charge the battery module 120. Furthermore, the voltage adaptation module further obtains a control charging instruction sent by the main control module, and analyzes and drives amplification of the control charging instruction, so that the voltage adaptation module can reduce the output voltage output to the battery module 120 or stop outputting the output voltage to the battery module 120 according to the control charging instruction.
The indication module 160 is coupled to the main control module, so that the indication module 160 can display the display information sent by the main control module, so that a user can know the operating state of the power supply apparatus 100. In this embodiment, the indication module 160 includes: after the indication module 160 acquires the display information, the indication module 160 analyzes and drives and amplifies the display information so as to facilitate the display of the LED display screen. Because, the display information includes: the temperature information and the state information, so that after the indication module 160 analyzes and drives and amplifies the display information and outputs the display information to its own LED display screen, the LED display screen can display the temperature information and the state information, so that a user can obtain information such as the electric quantity of the battery, the voltage of the battery, the temperature of the battery, and whether the battery is in a charging state or not by observing the indication module 160.
Referring to fig. 4, the number of the output interfaces 170 is also multiple, so that the output interfaces 170 can charge different types of external mobile devices through different types of connection lines, and thus the types of the output interfaces 170 are different. By way of one approach, the output interface 170 includes: a plurality of second dc power source interfaces 171, a plurality of fourth universal serial bus interfaces 172, a fifth universal serial bus interface 173, a sixth universal serial bus interface 174, and a second lightning interface 175.

The working principle of the charging device provided by the invention is as follows:
one or more charging interfaces 110 of the plurality of charging interfaces 110 obtain the power of the matched power supply 210 by coupling the matched power supply 210 with itself. The main control module can adjust the output voltage of the power supply 210 coupled to each charging interface 110, so that each charging interface 110 obtains the maximum output voltage of the power supply 210 matched with the type of the charging interface 110. The main control module detects whether the maximum output voltages output by each charging interface 110 are the same, and generates a coupling instruction to the voltage adaptation module according to the detection result. The voltage adaptation module is coupled to one or more charging interfaces 110 of the plurality of charging interfaces 110 according to the coupling instruction, so as to obtain a sum of the plurality of maximum output voltages as the input voltage, or obtain a maximum output voltage of the plurality of maximum output voltages as the input voltage. The main control module generates an adjustment command to the voltage adaptation module according to the input voltage value, and the voltage adaptation module outputs an output voltage having the same value as the input voltage value to the battery module 120 according to the adjustment command, so as to facilitate the fast charging of the battery module 120. The temperature detection module 130 may detect an operating temperature of the battery module 120, generate temperature information according to the detected operating temperature, and output the temperature information to the main control device 150. The main control module can acquire the temperature information, and when the temperature information acquired by the main control module is higher than or equal to the preset temperature information of the main control module, the main control module generates a charging control instruction to the voltage adaptation module. The voltage adaptation module reduces the output voltage output to the battery module 120 or stops outputting the output voltage to the battery module 120 according to the control charging instruction. And the battery module 120 can also transmit its own state information to the main control device 150. When the main control module obtains a control instruction input by the user through the key module 140, the main control module packages the temperature information and the state information according to the control instruction and sends the temperature information and the state information to the indicating module 160. The indicating module 160 displays the packaged temperature information and state information, and a user can acquire information such as the electric quantity of the battery, the voltage of the battery, the temperature of the battery, whether the battery is in a charging state or not by observing the indicating module 160. Meanwhile, when the charging apparatus is not in the charging state, the external mobile device is coupled to one or more of the plurality of output interfaces 170 through the connection line, so that the charging apparatus can charge the external mobile device.
Referring to fig. 5, an embodiment of the present invention further provides a charging method, where the charging method includes: step S100 and step S200.

Each charging interface 110 is configured to couple with a power supply 210 with a type matching with that of the charging interface 110, each charging interface 110 is coupled with an input end of the main control device 150, an output end of the main control device 150 is coupled with the battery module 120, and each output interface 170 is coupled with the battery module 120.
The charging interface 110 is provided in plurality, and since each charging interface 110 is used for coupling with the power supply 210 matched with the type of the charging interface 110, the charging device can be coupled with a plurality of matched power supplies 210 by simultaneously adapting to a plurality of different types of charging connecting lines. Each charging interface 110 is coupled to the input terminal of the main control device 150, so that the main control device 150 can form data interaction with the matching power supply 210 coupled to each charging interface 110 through each charging interface 110, and further, the main control device 150 can enable each charging interface 110 to acquire the output voltage of the power supply 210 coupled to the charging interface 110 through the data interaction.

If only one charging interface 110 is coupled to the matched power supply 210, the master control device 150 can obtain the input voltage input to the charging interface 110. If the charging interfaces 110 are coupled to the matched power source 210 and the types of the charging interfaces 110 are the same, the master control device 150 can obtain the sum of the maximum output voltages, which is less than or equal to the input voltage threshold preset by the master control device 150. If the charging interfaces 110 are coupled to the matched power source 210 and the types of the charging interfaces 110 are different, the master control device 150 can obtain the input voltage with the maximum value from the output voltages. Meanwhile, the master control device 150 can output an output voltage having the same value as the input voltage through its internal regulation.
Furthermore, the output terminal of the main control device 150 is coupled to the battery module 120, so that the main control device 150 can output an output voltage having the same value as the input voltage to the battery module 120. Thereby enabling the battery module 120 to be rapidly charged.
Therefore, the power supply device 100 can be coupled with the power supply 210 through various types of connection lines to charge itself through the plurality of charging interfaces 110. And the self-quick charging of the power supply device 100 is realized through the automatic adjustment of the main control device 150, so that the applicability of the power supply device 100 is effectively improved.
