Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for adjusting an output mode of a mobile power supply according to an embodiment of the present invention, where the embodiment is applicable to a condition of adjusting an output mode of a mobile power supply, and the method can be executed by an adjusting apparatus of an output mode of a mobile power supply, and specifically includes the following steps:
and S110, acquiring the actual voltage of the mobile power supply in real time.
For example, the mobile power supply may include a voltage detection circuit for detecting an actual voltage of the mobile power supply in real time. A mobile power supply generally includes three output modes: firstly, the output voltage is 9V, and the output current is 2A; secondly, the output voltage is 9V and 1A; and thirdly, the output voltage is 5V, and the output current is 2A. Specifically, when the mobile power supply outputs a high-point voltage current to the outside, for example, in the case of the above-described mode one output, the actual voltage inside the battery is usually about 4.2V at the maximum, and is converted into 9V by the voltage step-up conversion circuit and output. It should be noted that, here, acquiring the actual voltage of the mobile power source refers to the actual voltage inside the battery, for example, 4.2V.
S120, when the actual voltage is judged to be smaller than the first threshold value, the external terminal is informed to change the specified output mode;
wherein, the actual voltage obtained gradually decreases as the battery voltage is lost. And when the actual voltage is less than the first threshold value, informing the terminal equipment to change the specified output mode, for example, when the actual voltage is less than 3.7V, the mobile power supply interacts with the mobile terminal equipment and informs the external terminal to change from the output voltage of 9V, the output current of 2A, the output mode I to the output voltage of 9V, and the output current of 1A, the output mode II.
It should be explained that, the battery of the mobile power supply has a certain internal resistance, when a high-point voltage current is output to the outside, for example, in an output mode of "output voltage is 9V and output current is 2A", the internal resistance voltage of the battery is divided greatly, the internal energy consumption of the mobile power supply is more, and the energy that can be output is less, when the actual voltage is reduced to the power-off voltage of the low-voltage protection function of the mobile power supply, for example, the power-off voltage of the low-voltage protection function is 3V, the mobile power supply automatically cuts off the external discharge, enters the protection mode, and the energy in the mobile power supply cannot be released. When the mobile power supply is switched to the output mode II of 9V output voltage and 1A output voltage, the internal resistance voltage division of the battery is small, the energy consumed in the mobile power supply is less, and more energy can be released. Moreover, the output voltage of the long-time high-point voltage and current mode is 9V, the temperature of the mobile power supply is increased in a violent manner due to charging in the mode of 2A output current, part of electric quantity of the mobile power supply is consumed in heating instead of charging the mobile terminal, the output efficiency of the mobile power supply is reduced, after the low-current output mode is switched, heat consumption is reduced, and the discharging efficiency is improved.
S130, controlling the power output circuit to output according to the designated output mode after external change;
wherein the output voltage of the designated output mode after the change is smaller than the output voltage of the designated output mode before the change, and/or the output current of the designated output mode after the change is smaller than the output current of the designated output mode before the change.
The first threshold is greater than a power-down voltage corresponding to the low-voltage protection function.
Fig. 3 is a structural assembly diagram of a mobile power supply according to a second embodiment of the present invention, and as shown in fig. 3, the mobile power supply includes a battery pack 10, a voltage detection circuit 20, a central control circuit 30, and a power output circuit 40. When the actual voltage is less than the first threshold, the central control circuit 30 of the mobile power supply interacts with the mobile terminal to notify the mobile terminal to change the output mode, and controls the power output circuit 40 to output according to the changed output mode, for example, notify the mobile terminal to change from "output voltage is 9V, output current is 2A" output mode one to "output voltage is 9V, output current is 1A" output mode two "to current reduction mode, and further notify the mobile terminal to change from" output voltage is 9V, output current is 2A "output mode one to" output voltage is 5V, output current is 2A "output mode three to voltage reduction mode, of course, the output mode can also be changed from" output voltage is 9V, output current is 1A "output mode two to" output voltage is 5V, and output current is 2A "output mode three.
When the actual voltage is greater than the first threshold value, after the mobile power supply interacts with the mobile terminal, the power output circuit 40 is controlled to output according to the current output mode, that is, when power is supplied to the outside according to the output mode before the mobile power supply is changed, for example, "the output voltage is 9V, and the output current is 2A" output mode — power supply to the outside.
When the voltage of the mobile power supply is consumed to a certain voltage, the mobile power supply can enter low-voltage protection, the power supply of the mobile power supply to the outside is automatically cut off, for example, before the power-off voltage of the low-voltage protection function, the mobile terminal is informed to switch an output mode, and the mobile power supply is guaranteed to supply power to the outside in real time.
The embodiment of the invention obtains the actual voltage of the mobile power supply in real time; when the actual voltage is judged to be smaller than the first threshold value, the external terminal is informed to change the specified output mode; controlling the power output circuit to output according to the designated output mode after external change; wherein the output voltage of the designated output mode after the change is smaller than the output voltage of the designated output mode before the change, and/or the output current of the designated output mode after the change is smaller than the output current of the designated output mode before the change. According to the method, the automatic output regulation mode of the mobile power supply reduces efficiency loss caused by high temperature, reduces the influence of virtual voltage, releases the actual electric quantity of the mobile power supply as much as possible, and improves the discharging efficiency of the mobile power supply.
Example two

s220, when judging whether the actual voltage is smaller than the first threshold value, informing the external terminal to change the specified output mode;
s230, controlling the power output circuit to output according to the designated output mode after external change;
wherein the output voltage of the designated output mode after the change is smaller than the output voltage of the designated output mode before the change, and/or the output current of the designated output mode after the change is smaller than the output current of the designated output mode before the change.
S240, when the actual voltage is judged to be smaller than the second threshold value, the external terminal is informed to change the specified output mode again;
for example, when the first threshold is 3.7V, the second threshold may be 3.3V, specifically, when the actual voltage is less than 3.3V, the mobile terminal notifies the external terminal to change the output mode again, for example, the output mode is changed from "the output voltage is 9V," the output current is 1A, "the output mode is two, more," the output voltage is 5V, "and the output current is 2A," after the mode is changed, the divided voltage of the internal resistance of the battery is further reduced, to a certain extent, the actual voltage of the battery is more output, and in the low-voltage mode, the heat loss is relatively small, the energy in the battery can be released more comprehensively, and the discharge efficiency of the mobile power supply is further improved.
S250, controlling the power output circuit to output according to the specified output mode changed again by the external terminal;
wherein the second threshold is less than the first threshold;
the output voltage of the specified output pattern after the re-change is smaller than the output voltage of the specified output pattern before the re-change, and/or the output current of the specified output pattern after the re-change is smaller than the output current of the specified output pattern before the re-change.
It should be noted that the number of times the mobile terminal changes the output mode is limited, which does not affect the external charging efficiency of the mobile power supply.
Optionally, the terminal device is a mobile phone and/or a tablet computer.
When the actual voltage is further judged to be smaller than the second threshold value, the external terminal is informed to change the specified output mode again; controlling the power output circuit to output according to the specified output mode after the external terminal is changed again; with the further loss of the voltage of the battery in the mobile power supply, the internal resistance of the battery is further reduced when the mobile power supply is switched to different output modes, more energy in the battery can be released, and in the low-voltage mode, the heat loss is relatively small, more energy in the battery can be released comprehensively, and the discharging efficiency of the mobile power supply is further improved.
