And step 210, obtaining power supply requirement information from the electric equipment.
Wherein the power supply requirement information at least comprises one of input voltage, input current and input power required by the electric equipment.
When the power consumption device does not have a battery and needs an external power supply or a power supply device to operate, the input voltage in the power supply request information of the power consumption device may be the rated voltage of the power consumption device, the input current in the power supply request information may be the rated current of the power consumption device, and the input power in the power supply request information may be the rated power of the power consumption device. The power supply device in this embodiment can supply power to the electric device, so that the electric device works normally.
In the case where the electric device itself includes a battery and the battery can be repeatedly charged, the input voltage in the electric power supply request information may be a charging voltage required when the battery in the electric device is charged, and the input current in the electric power supply request information may be a charging current required when the battery in the electric device is charged. The power supply apparatus in this embodiment can charge the battery in the electric device.
In one example, the power supply device may communicate with the powered device in several ways:
firstly, a connecting line is connected between the power supply device and the electric equipment, and the connecting line can be used for data transmission; the power supply device communicates with the electric equipment by using the connecting line, and acquires power supply requirement information from the electric equipment. The connecting line may be a USB data line.

There may be a plurality of consumers around the power supply. Optionally, the power supply device obtains the power supply requirement information only from the electrical equipment with the smallest distance.
Alternatively, the power supply apparatus may provide the power supply requirement information of the power consuming device with the minimum distance to the user in order to determine whether the power consuming device with the minimum distance is a power supply target (the power supply target generally refers to a power consuming device connected to the power supply apparatus via a connection line). For example, the power supply requirement information is displayed in a display screen; for another example, the power supply requirement information is voice-broadcast.
If the power supply apparatus does not receive the charging confirmation signal within the predetermined time after providing the power supply requirement information, the power supply apparatus may obtain the power supply requirement information of the other peripheral electric devices except the electric device having the smallest distance to the peripheral electric device, and provide the obtained power supply requirement information to the user, or may perform step 220. When receiving the charging confirmation signal, the power supply device determines the power supply request information that was last provided to the user as the power supply request information of the power supply object.
The charging confirmation signal may be an operation signal generated when a confirmation button on the power supply device is operated, or may be a voice signal whose voice content collected by the voice collection device by the power supply device is "confirmed", and the charging confirmation signal is not specifically limited in this embodiment.
In the above, taking the example of obtaining the power supply requirement information from the electrical equipment with the smallest distance to the electrical equipment as an example, in actual implementation, the power supply apparatus may further display a plurality of surrounding electrical equipments, receive a selection instruction for selecting a certain electrical equipment, and obtain the power supply requirement information of the selected electrical equipment after receiving the selection instruction.
In another example, in a case where the power supply apparatus can communicate with the electric device, the power supply apparatus can acquire the power supply requirement information from the electric device by the following several ways:
firstly, sending an acquisition request to electric equipment, wherein the acquisition request is used for triggering the electric equipment to feed back stored power supply requirement information to a power supply device; and the electric equipment sends power supply requirement information to the power supply device according to the acquisition request.
Optionally, the power supply device sends the acquisition request to the electrical equipment after detecting that the power supply interface of the power supply device is connected to any electrical equipment through the connecting line.
For example, after detecting that the power supply interface of the power supply device is connected to any electric device through a connection line, the power supply device may send an acquisition request to the electric device through the connection line; or sending an acquisition request to all surrounding electric equipment by a wireless communication technology; the method can also send the acquisition request to the electric equipment closest to the electric equipment through the wireless communication technology, and can also send the acquisition request to the selected electric equipment through the wireless communication technology.
And secondly, when the electric equipment detects that the power supply device connected with the power interface or the charging interface of the electric equipment is arranged, the electric equipment sends power supply requirement information of the electric equipment to the power supply device, and the power supply device receives the power supply requirement information actively sent by the electric equipment.
For example, when detecting that there is a power supply device connected to the power interface or the charging interface of the electric device, the electric device may send power supply requirement information to the power supply device through the connection line; the power supply requirement information can also be sent to all the power supply devices around the power supply device through the wireless communication technology; and the power supply requirement information can also be sent to the power supply device closest to the power supply device through the wireless communication technology.
Optionally, when the power supply device acquires the power supply requirement information of a certain piece of electrical equipment through the wireless communication technology, the power supply requirement information may be provided to the user for confirmation. For example, the power supply device displays the power supply requirement information in its display screen for confirmation by the user. The power supply device executes step 230 when receiving a confirmation signal for confirming that the power supply requirement information is correct. If the power supply requirement information displayed by the power supply device is not the power supply requirement information of the electrical equipment to be charged, the user can directly input the power supply requirement information of the electrical equipment to be charged on the power supply device, specifically please refer to step 220.
This step can be achieved in several ways:
the power supply device further comprises a display screen, wherein the display screen can be used for displaying multiple groups of candidate power supply requirement information, and each group of candidate power supply requirement information comprises at least one of output voltage, output current and output power; and determining the power supply requirement information of the electric equipment selected by the user.
Each set of candidate power supply requirement information can be set by a technical developer or a user, the output voltage in each set of candidate power supply requirement information can be the input voltage required by any electric device on the market, the output current in each set of candidate power supply requirement information can be the rated current or the charging current required by any electric device on the market, and the output power in each set of candidate power supply requirement information can be the rated power required by any electric device on the market.
It should be noted that, if a user can directly select a set of candidate power supply requirement information, the power supply apparatus determines the set of candidate power supply requirement information as the power supply requirement information of the power consumption device. The user may also select an output voltage and/or an output current and/or an output power from the plurality of sets of candidate power supply requirement information, and the output voltage, the output current and the output power selected by the user may not be in the same set of candidate power supply requirement information.
By way of example, each set of candidate power supply requirement information includes only output voltages, the power supply device displays a plurality of output voltages in its display screen; and determining the output voltage selected by the user as the input voltage required by the electric equipment.
Secondly, the power supply device also comprises a display screen, wherein an input frame for inputting the input voltage required by the electric equipment can be displayed in the display screen; the voltage input in the input box is determined as the input voltage of the consumer electrical device.
Optionally, the display screen may further display an input frame for inputting an input current required by the electric device; the current input in the input box is determined as the input current of the consumer electrical device.
Optionally, the display screen may further display an input box for inputting the input power required by the electric device; the power input in the input box is determined as the input power of the consumer electronic device.
Thirdly, the power supply device also comprises a voice acquisition device which can acquire voice signals by utilizing the voice acquisition device; and analyzing the voice signal, and generating power supply requirement information of the user equipment according to the voice signal.
The specific implementation can be as follows: the power supply device can be provided with a voice key, and a user can press the voice key for a long time and speak power supply requirement information of the electric equipment. Correspondingly, when the power supply device detects an operation signal generated when the voice key is pressed, the voice acquisition device is used for acquiring a signal to obtain a voice signal; and analyzing the voice content in the voice signal, and extracting the power supply requirement information from the voice content.
For example, three key groups are pre-stored in the power supply device, and the three key groups are respectively: 1. input voltage, volts; 2. inputting current and ampere; 2. input power, watts. The user presses the voice button and speaks that the input voltage is 5 volts, and then the voice content extracted from the voice signal collected by the voice collecting device by the power supply device is that the input voltage is 5 volts. And if the power supply device determines that the voice content comprises the first group of keywords, extracting a value 5 among the first group of keywords, and determining that the input voltage of the power consumption equipment is 5 volts according to 5 volts.
Optionally, in this embodiment, step 210 may be performed first, then step 230 may be performed, and step 220 may not be performed; alternatively, step 220 may be performed first, step 230 may be performed, and step 210 may not be performed.
And step 230, outputting the electric energy to the electric equipment according to the power supply requirement information.
Hereinafter, an example will be described in which, when the power supply request information includes an input voltage, an output voltage having a value equal to the input voltage is output to the electric equipment. In addition, when the power supply requirement information comprises input current, output current with the value equal to the input current is output to the electric equipment; when the power supply requirement information comprises input power, the power supply requirement information outputs output power with the value equal to the input power to the electric equipment.
Optionally, the output voltage of the power supply device with the value equal to the input voltage can be implemented in the following two ways:
first, the power supply device includes a voltage conversion circuit for providing an output voltage; the voltage conversion circuit is provided with a feedback circuit which is used for feeding back the output voltage of the power supply device to a processor in the power supply device; the processor in the power supply device adjusts a Pulse Width Modulation (PWM) duty ratio according to the processor feedback output voltage, and adjusts the output voltage provided by the voltage conversion circuit by a PWM technique, so that the output voltage has an output value equal to the input voltage.
Secondly, a coupling inductance circuit is arranged in the power supply device, and the output voltage of the power supply device is changed by adjusting the number of turns of a mutual inductance coil in the coupling inductance circuit.
Under the condition that the power supply requirement information simultaneously comprises input voltage, input current and input power, calculating a product result of the input voltage and the input current; if the product result is not equal to the input power, prompt information is displayed, and power supply requirement information input by a user is obtained again, wherein the prompt information is used for prompting that the input power input by the user is not matched with the input voltage and the input current.
For reference, step 220 in this embodiment may be referred to for reacquiring the power supply requirement information input by the user, which is not described herein again.
In summary, in the method provided in this embodiment, the power supply requirement information of the electrical device is obtained, where the power supply requirement information at least includes one of an input voltage, an input current, and an input power required by the electrical device; outputting electric energy to the electric equipment according to the power supply requirement information; the power supply device can provide electric energy for the electric equipment according to the power supply requirement information required by the electric equipment, and the problems that the type of the electric equipment capable of supplying power is limited and the use range is small due to the fact that the power supply voltage provided by the power supply source is usually fixed in the related art are solved; the effects of expanding the application range of the power supply and the power supply device and supplying power to more kinds of electric equipment are achieved.
In one example, the power supply device further comprises a battery and a charging interface, by means of which the battery of the power supply device can be repeatedly charged. The power supply device may be part of a battery-equipped electric device such as an electronic cigarette, a mobile power supply, a mobile phone, or the like. In order to ensure the normal operation of the electrical equipment where the power supply device is located, the power supply device may further perform several steps as shown in fig. 3 before performing step 230.
In one example, step 222 can be implemented in several ways:
first, when the remaining power of the power supply device is lower than a preset first threshold, the step 230 is stopped.
Wherein the first threshold is set by a system developer. Taking the first threshold as 500 ma-hr as an example, in the case that the remaining power of the power supply device is 499 ma-hr, the power supply device stops executing step 230.
Secondly, determining the residual capacity of the power supply device according to the residual capacity of the power supply device; when the remaining power is lower than the preset second threshold, the step 230 is stopped.
The residual electric quantity of the power supply device is the proportion of the residual electric quantity of the power supply device in the rated capacity; the second threshold may be set by a system developer or by a user, for example, the remaining capacity may be set to 20%.
For example, when the remaining power of the power supply device is 199 ma and the rated capacity of the battery of the power supply device is 1000 ma, the remaining power of the power supply device is lower than 20%, and the power supply device stops executing step 230.
Thirdly, determining a first power supply time length according to the residual electric quantity and the power supply requirement information, wherein the first power supply time length is a time length for which the power supply device can continuously output the voltage and the current which meet the power supply requirement information; displaying the first power supply duration and acquiring a second power supply duration; when the duration of continuously outputting the voltage and the current according to the power supply requirement information reaches the second power supply duration, the step 230 is stopped.
The specific implementation of determining the first power supply duration according to the remaining power amount and the power supply requirement information may be: the power supply device can determine first power consumption of the electric equipment according to the power supply requirement information; and dividing the current remaining electric quantity by the first power consumption of the electric equipment to obtain a first power supply duration.
For example, when the remaining power of the power supply device is 1300 ma, the output current of the electrical equipment is determined to be 1300 ma according to the power supply requirement information, the first power supply duration obtained by dividing 1300 ma by 1300 ma is 1 hour, and the power supply duration is shown to be 1 hour. The power supply device can continuously supply power for 1 hour to the electric equipment under the condition that the user knows that the power supply device uses all electric quantity to supply power to the electric equipment.
In the case where the power supply device is part of an electric device having a battery, such as an electronic cigarette, a portable power source, a mobile phone, or the like, the normal operation of the electric device in which the power supply device is located consumes the electric power of the battery. For example, when the power supply device is part of an electronic cigarette, a user simulating smoking with the electronic cigarette also consumes power from a battery in the power supply device. Therefore, the specific implementation of determining the first power supply duration according to the remaining power amount and the power supply requirement information may further be: acquiring second power consumption which is pre-stored locally and is used when the electric equipment where the power supply device is located works normally, and determining first power consumption of the electric equipment according to the power supply requirement information; and dividing the remaining electric quantity by the sum of the second electric power consumption and the first electric power consumption to obtain a first power supply duration. At this time, the first power supply duration is the longest duration for which the power supply device continuously supplies power to the electrical equipment under the condition that the power supply device normally works. Alternatively, the first power consumption amount and the second power consumption amount may be calculated according to the current actual power consumption of the device, and of course, may also be an average power consumption amount obtained by historical statistics stored in the device in advance, for example, taking the average power consumption amount obtained by the historical statistics as an example, assuming that the power supply device consumes 10W per hour in normal operation, the first power consumption amount is 10, and similarly, assuming that the power consumption device consumes 15W per hour in operation, the second power consumption amount is 15. Of course, in actual implementation, the first power consumption and the second power consumption may be obtained in other manners, which is not described herein again.
In addition, after the power supply device determines the first power supply time, the first power supply time can be displayed in the display screen, and the user can be reminded of the first power supply time in a voice mode. After knowing the first power supply duration, in order to ensure that the power supply device has the remaining power to supply power to the electric equipment to work, the user can submit a second power supply duration to the power supply device, wherein the second power supply duration is lower than the first power supply duration. And the power supply device stops executing step 230 when detecting that the time period for which the power supply device continuously supplies power to the electric equipment reaches the second power supply time period.
Wherein, submitting the second power supply duration to the power supply device may be:
firstly, displaying an input frame for filling a second power supply duration when a first power supply duration is displayed in a display screen; and acquiring a second power supply time length input in the input frame.
Secondly, when the first power supply time length is provided for the user, a voice signal is collected by a voice collecting device; and analyzing the voice content in the voice signal, and acquiring a second power supply time length from the voice content.
In one example, during the execution of step 230 and before the stop of the execution of step 230, the power supply device may further provide the user with inquiry information for inquiring whether the user stops charging; the power supply apparatus stops performing step 230 when receiving the confirmation signal for confirming the stop of charging.
Optionally, the power supply device continues to perform step 230 when receiving the operation signal for denying stopping the charging.
In one example, the power supply device includes a power supply interface that is a USB (Universal Serial Bus) port. Generally speaking, when providing an electric device for a user, a manufacturer also provides a connection line adapted to the electric device, and one port of the connection line is a USB port and can also be used for connecting with a power supply interface of a power supply device; the other port of the connecting line is matched with a charging interface or a power supply interface of the electric equipment. The user can directly utilize the connecting wire of the electric equipment to connect the power supply device with the electric equipment, and the power supply device can utilize the connecting wire to provide electric energy for the electric equipment.
Optionally, when the manufacturer provides the power supply device to the user, the manufacturer also provides a connection line adapted to the power supply device. One port of the connecting wire is a USB port and can be used for being connected with a power supply interface. Therefore, a user can conveniently connect the power supply device with the electric equipment by using the connecting wire of the power supply device, and the power supply device can supply electric energy to the electric equipment by using the connecting wire.
Optionally, the charging interface on the power supply device is different from the power supply interface. For example, when the power supply interface of the power supply device is a USB port, the charging interface of the power supply device is not the USB port.
The power supply device in the present invention may include a processor for executing computer program instructions to perform various procedures and methods, and a memory for storing program instructions, the processor being capable of implementing the power supply method in any of the above embodiments by executing the program instructions.
