Description

Technical Field

[0001] This application relates to the technical field of mobile power supplies, and in particular, to a fast charging method, system, device, and storage medium based on a mobile power supply. Background Art

[0002] A mobile power supply is a portable battery device that can be used to charge various terminal devices, such as smartphones, projectors, tablets, Bluetooth headsets, etc. When there is no power outlet nearby, the mobile power supply provides a convenient way for users to charge. The mobile power supply contains one or more rechargeable batteries inside and is equipped with corresponding charging circuits and output ports. Users can connect the terminal device through the output port and charge the terminal device, thereby extending its usage time.

[0003] With the continuous improvement of the quantity and performance of terminal devices, the power consumption of terminal devices is also increasing. Therefore, terminal devices need to be charged frequently. Users hope that the mobile power supply can charge at the maximum power under the condition of meeting the charging threshold value of the terminal device, so as to achieve the purpose of charging the terminal device in the shortest time. However, limited by the battery parameters of the terminal device and the charging parameters of the mobile power supply, the mobile power supply cannot reach its optimal output value, which further leads to slow power supply efficiency of the mobile power supply for the terminal device. This situation needs to be improved. Summary of the Invention

[0004] To solve the problem of slow power supply efficiency of the existing mobile power supply for terminal devices, this application provides a fast charging method, system, device, and storage medium based on a mobile power supply, and adopts the following technical solutions:

[0005] In a first aspect, this application provides a fast charging method based on a mobile power supply, including:

[0006] If N output ports of the mobile power supply are connected to the terminal device, obtain the output parameters corresponding to the N output ports and the charging parameters of the terminal device, where N is an integer greater than or equal to 2;

[0007] Determine whether the output parameters match the charging parameters;

[0008] If the output parameters do not match the charging parameters, determine a first target difference between the output parameters and the charging parameters;

[0009] Determine adjustment parameters corresponding to the N output ports according to the first target difference;

[0010] Send a first prompt message according to the adjustment parameters, where the first prompt message is used to instruct the user to adjust the N output ports to obtain M output ports, where M is an integer greater than or equal to 1;

[0011] Charge the terminal device based on the M output ports.

[0012] By adopting the above technical solution, N output ports of the mobile power supply are connected to the terminal device. Among them, the number of charging ports through which the terminal device is connected to the mobile power supply is 1, that is, N output ports are connected to 1 charging port. Then, obtain the output parameters corresponding to the N output ports, and obtain the charging parameters of the terminal device, and determine whether the output parameters match the charging parameters. If the output parameters and the charging parameters match, determine the first target difference between the output parameters and the charging parameters, and determine the adjustment parameters corresponding to the N output ports according to the first target difference, and send a first prompt message according to the adjustment parameters. The first prompt message is used to instruct the user to adjust the N output ports. For example, adjust the original 2 output ports to 3 output ports, or adjust the original 2 output ports to 1 output port. That is, the adjustment of the N output ports is specifically to increase or decrease the number of output ports to obtain M output ports, and charge the terminal device based on the M output ports; the solution in this application adjusts the output voltage based on the number of adjusted output ports, so that the mobile power supply can reach the optimal value of its output while meeting the charging threshold of the terminal device, thereby solving the problem that the existing mobile power supply has a slow power supply efficiency for the terminal device.

[0013] Optionally, the charging the terminal device based on the M output ports includes:

[0014] If M is greater than or equal to 2, obtain the output voltage of each output port among the M output ports and the remaining power of each battery pack among the M battery packs corresponding to the M output ports;

[0015] Charge the terminal device according to the output voltage of each output port and the remaining power of each battery pack.

[0016] By adopting the above technical solution, when M is equal to 1, the terminal device is directly charged by this output port, and the output voltage of the output port is adjusted to reach the optimal value of the mobile power supply output under the condition of meeting the charging threshold of the terminal device; when M is greater than or equal to 2, obtain the output voltage of each output port among the M output ports, and the remaining power of each battery pack among the M battery packs corresponding to the M output ports, and charge the terminal device according to the output voltage of each output port and the remaining power of each battery pack. The output voltage of the corresponding output port can be adjusted according to the remaining power of the battery pack, so that the mobile power supply charges with the maximum power, which is beneficial to improving the power supply efficiency of the mobile power supply for the terminal device.

[0017] Optionally, charging the terminal device according to the output voltage of each output port and the remaining power of each battery pack includes:

[0018] Determine the output level of the remaining power of each battery pack;

[0019] Adjust the output voltage of the M output ports according to the output level, and the adjusted output voltage of the M output ports matches the charging voltage in the charging parameters;

[0020] Charge the terminal device based on the adjusted output voltage of the M output ports.

[0021] By adopting the above technical solution, the specific steps of charging the terminal device according to the output voltage of each output port and the remaining power of each battery pack are as follows: First, determine the output level of the remaining power of each battery pack. For example, level 1 is the remaining power of 91%-100%, level 2 is the remaining power between 81%-90%, and so on. Second, adjust the output voltage of the M output ports according to the output level. For example, the higher the level, the higher the output voltage, or the lower the level, the lower the output voltage. No matter which way is used for adjustment, the adjusted output voltage of the M output ports always matches the charging voltage of the charging parameters. Finally, charge the terminal device based on the adjusted output voltage of the M output ports.

[0022] Optionally, charging the terminal device according to the output voltage of each output port and the remaining power of each battery pack includes:

[0023] Determine a second target difference between the remaining power of the target battery pack and a preset power threshold, where the target battery pack is any one of the M battery packs;

[0024] Adjust the output voltage of the output port corresponding to the target battery pack according to the second target difference;

[0025] Charge the terminal device based on the adjusted output voltage.

[0026] By adopting the above technical solution, the specific steps for charging the terminal device are as follows: First, determine the second target difference between the remaining power of the target battery pack and the preset power threshold. The preset power threshold is a value set in advance. If the second target difference is less than or equal to the preset power threshold, disconnect the target battery pack from the terminal device; on the premise that the second target difference is greater than the preset power threshold, adjust the output voltage of the output port according to the magnitude of the second target difference. If the second target difference is relatively large, increase the output voltage. If the second target difference is relatively small, decrease the output voltage to achieve the purpose of simultaneously depleting the power of M battery packs. Finally, charge the terminal device based on the adjusted output voltage.

[0027] Optionally, charging the terminal device according to the output voltage of each output port and the remaining power of each battery pack includes:

[0028] Judge whether there is a first battery pack with a remaining power less than the first preset threshold and a second battery pack with a remaining power greater than the second preset threshold among the M battery packs;

[0029] If so, disconnect the connection between the first battery pack and the first output port, and increase the output voltage of the second output port corresponding to the second battery pack, where the first output port is the output port among the M output ports connected to the first battery pack, and the second output port is the output port among the M output ports connected to the second battery pack;

[0030] Charge the terminal device based on the second output port after increasing the output voltage.

[0031] By adopting the above technical solution, the specific steps for charging the terminal device are as follows: If there is a first battery pack with a remaining power less than the first preset threshold and a second battery pack with a remaining power greater than the second preset threshold among the M battery packs, first disconnect the connection between the first battery pack and the first output port to enable the first battery pack to retain a certain amount of power, increase the output voltage of the second output port corresponding to the second battery pack, and charge the terminal device based on the second output port after increasing the output voltage. At this time, the first battery pack does not supply power to the terminal device, and the second battery pack supplies power to the terminal device.

[0032] Optionally, the method further includes:

[0033] Real-time monitor the remaining power of the second battery pack;

[0034] If the remaining power of the second battery pack reaches the first preset threshold, connect the first battery pack to the first output port;

[0035] Reduce the output voltage of the second output port;

[0036] Charge the terminal device based on the second output port and the first output port after reducing the output voltage.

[0037] By adopting the above technical solution, the remaining power of the second battery pack is monitored in real time. When the remaining power of the second battery pack reaches the first preset threshold, the first battery pack and the first output port are connected, and the output voltage of the second output port is reduced so that the output voltage of the second output port is the same as the output voltage of the first output port. Charge the terminal device based on the second output port and the first output port after reducing the output voltage. At this time, the first battery pack and the second battery pack supply power to the terminal device at the same time, so that the remaining power of the first battery pack and the remaining power of the second battery pack tend to be exhausted at the same time.

[0038] Optionally, after charging the terminal device based on the M output ports, the method includes: determining the real-time output voltage when charging the terminal device through the target output port and the reference voltage range of the target output port, where the target output port is any one of the M output ports;

[0039] Judge whether the real-time output voltage is within the reference voltage range;

[0040] If the real-time output voltage is not within the reference voltage range, a second prompt message is sent to prompt the user to replace the target output port with other output ports among the N output ports except the M output ports;

[0041] Adjust the output parameters of the other output ports according to the output parameters of the target output port, and charge the terminal device based on the other output ports after adjusting the output parameters.

[0042] By adopting the above technical solution, determine the real-time output voltage when the target output port charges the terminal device, and determine the reference voltage range of the target output port, and judge whether the real-time output voltage is within the reference voltage range. When the real-time output voltage is within the reference voltage range, the target output port continues to be connected to the terminal device; when the real-time output voltage is not within the reference voltage range, a second prompt message is sent. The second prompt message is used to prompt the user to replace the target output port with other output ports among the N output ports except the M output ports, and adjust the output parameters of the other output ports so that the output parameters of the other output ports are the same as the output parameters of the target output port. Finally, charge the terminal device based on the other output ports after adjusting the output parameters.

[0043] In a second aspect, the present application provides a fast charging system based on a mobile power supply, including:

[0044] An acquisition module, configured to acquire output parameters corresponding to the N output ports and charging parameters of the terminal device if the N output ports of the mobile power supply are connected to the terminal device, where N is an integer greater than or equal to 2; a judgment module, configured to judge whether the output parameters match the charging parameters;

[0045] A determination module, configured to determine a first target difference between the output parameters and the charging parameters if the output parameters do not match the charging parameters;

[0046] An adjustment module, configured to determine adjustment parameters corresponding to the N output ports according to the first target difference;

[0047] A prompt module, configured to send a first prompt message according to the adjustment parameters, where the first prompt message is used to instruct the user to adjust the N output ports to obtain M output ports, where M is an integer greater than or equal to 1; a charging module, configured to charge the terminal device based on the M output ports.

[0048] By adopting the above technical solution, first, when the N output ports of the mobile power supply are connected to the terminal device, the acquisition module acquires the output parameters corresponding to the N output ports and the charging parameters of the terminal device; then, the judgment module judges whether the output parameters match the charging parameters. Next, when the output parameters do not match the charging parameters, the determination module determines the first target difference between the output parameters and the charging parameters. Then, the adjustment module determines the adjustment parameters corresponding to the N output ports according to the first target difference. Next, the prompt module sends a first prompt message according to the adjustment parameters. The first prompt message is used to instruct the user to adjust the N output ports, that is, the adjustment of the N output ports is specifically to increase or decrease the number of output ports to obtain M output ports. Finally, the terminal device is charged based on the M output ports. The solution in the present application adjusts the output voltage by adjusting the number of output ports, so that the mobile power supply can reach its optimal output value while meeting the charging threshold of the terminal device, thereby solving the problem of slow power supply efficiency of the existing mobile power supply for the terminal device.

[0049] In a third aspect, the present application provides an electronic device, including a memory and a processor, and a computer program capable of being loaded and executed by the processor and implementing the fast charging method based on a mobile power supply as described in the first aspect is stored on the memory.

[0050] Fourthly, the present application provides a computer-readable storage medium storing a computer program that can be loaded and executed by a processor to perform the fast charging method based on a mobile power supply as described in the first aspect.

[0051] In summary, it can be seen that in the embodiments provided by the present application, N output ports of the mobile power supply are connected to the terminal device, the output parameters corresponding to the N output ports and the charging parameters of the terminal device are obtained, and it is determined whether the output parameters match the charging parameters. If the output parameters and the charging parameters match, a first target difference between the output parameters and the charging parameters is determined, and adjustment parameters corresponding to the N output ports are determined according to the first target difference. A first prompt message is sent according to the adjustment parameters. The first prompt message is used to instruct the user to adjust the N output ports, that is, the adjustment of the N output ports specifically refers to increasing or decreasing the number of output ports to obtain M output ports, and charging the terminal device based on the M output ports; in the solution of the present application, the adjustment parameters are determined by the first target difference, and the number of output ports is adjusted by the adjustment parameters, so as to realize the adjustment of the output voltage, so that the mobile power supply can reach the optimal value of its output when meeting the charging threshold value of the terminal device, thereby solving the problem that the existing mobile power supply has a slow power supply efficiency for the terminal device.

It should also be understood that the term "and / or" used in the present application refers to any and all possible combinations including one or more of the listed items.

[0056] Hereinafter, the terms "first" and "second" are only for descriptive purposes and should not be construed as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0057] An embodiment of the present application discloses a fast charging method based on a mobile power supply.

[0058] Referring to Figure 1 , Figure 1 is a schematic flowchart of the fast charging method based on a mobile power supply provided by the embodiments of the present application. The method includes the following steps:

[0059] S10. If N output ports of the mobile power supply are connected to the terminal device, obtain the output parameters corresponding to the N output ports and the charging parameters of the terminal device, where N is an integer greater than or equal to 2;

[0060] Among them, there are at least two output ports of the mobile power supply connected to the terminal device. The connection line between the terminal device and the mobile power supply integrates a communication function, so that the mobile power supply can supply power to the terminal device, and obtain the output parameters corresponding to the N output ports and the charging parameters of the terminal device, and determine the power supply mode of the mobile power supply to the terminal device according to the output parameters and the charging parameters. It should be noted that the terminal device can be an electronic device such as a mobile phone, a tablet computer, a smart wearable device, a computer, etc.

[0061] It should be noted that the charging parameter can be a charging current or a charging voltage, and is not specifically limited. The output parameter of the output port of the mobile power supply is the same as the charging parameter of the terminal device. If the charging parameter of the terminal device is a charging current, the output parameter of the output port of the mobile power supply is an output current. If the charging parameter of the terminal device is a charging voltage, the output parameter of the output port of the mobile power supply is an output voltage.

[0062] S20. Determine whether the output parameter matches the charging parameter;

[0063] Among them, if it is necessary to determine whether the mobile power supply can supply power to the terminal device, it is necessary to determine whether the output parameter and the charging parameter of the mobile power supply match. If the output parameter and the charging parameter match, it is determined that the mobile power supply reaches the optimal value of the output, which is beneficial to improving the power supply efficiency of the mobile power supply to the terminal device. It should be noted that if the output parameter is an output voltage and the charging parameter is a charging voltage, the matching of the output parameter and the charging parameter is that the output voltage is consistent with the charging voltage.

[0064] If the output parameters and charging parameters do not match, first, it is necessary to determine whether the output parameters are greater than the charging parameters. When it is determined that the output parameters of the mobile power supply exceed the charging threshold value of the terminal device, it is easy to cause damage to the terminal device. Second, it is necessary to determine whether the output parameters are much smaller than the charging parameters. When the mobile power supply charges the terminal device, the optimal output value cannot be reached, which in turn leads to slow power supply efficiency of the mobile power supply for the terminal device.

[0065] That is, when the mobile power supply charges the terminal device with overvoltage power supply (the output voltage of the mobile power supply is greater than the charging voltage allowed by the terminal device), the battery of the terminal device is easily damaged; when the mobile power supply charges the terminal device with low-voltage power supply (the output voltage of the mobile power supply is less than the charging voltage allowed by the terminal device), the power supply efficiency is easily slow.

[0066] S30. If the output parameters and charging parameters do not match, determine the first target difference between the output parameters and the charging parameters;

[0067] Among them, when the output parameters and charging parameters do not match, determine the first target difference. The first target difference is the difference between the output parameters and the charging parameters. Through the first target difference, the power supply situation of the mobile power supply and the terminal device can be fed back. Taking the output parameters and charging parameters as voltages as an example, for example, the output parameter is 3.5V and the charging parameter is 5.0V, then the first target difference is 1.5V.

[0068] S40. Determine the adjustment parameters corresponding to the N output ports according to the first target difference;

[0069] Among them, after determining the first target difference, determine the adjustment parameters corresponding to the N output ports according to the first target difference. The feedback of the adjustment parameters continuously adjusts the output voltage and output current of the mobile power supply to improve the power supply efficiency of the mobile power supply for the terminal device. It should be noted that the adjustment parameters are for the N output ports as a whole and do not adjust a certain output port alone.

[0070] S50. Send a first prompt message according to the adjustment parameters. The first prompt message is used to instruct the user to adjust the N output ports to obtain M output ports, where M is an integer greater than or equal to 1;

[0071] Among them, after determining the adjustment parameters, send a first prompt message according to the adjustment parameters. The first prompt message is used to instruct the user to adjust the N output ports to obtain M output ports, that is, the first prompt message is used to instruct the user to adjust the number of output ports. As Figure 2 shown, Figure 2 is a schematic diagram of the mobile power supply supplying power to the terminal device provided by the embodiment of the present application. Among them, Figure 2Wherein, a in [description] is a schematic diagram of simultaneously powering a terminal device by two output ports. Figure 2 Wherein, b in [description] is a schematic diagram of simultaneously powering a terminal device by three output ports. When the mobile power supply can meet the charging threshold value of the terminal device, according to the first prompt message, it instructs the user to adjust the original two output ports to three output ports, or adjust the original two output ports to one output port. The first prompt message is used to prompt the user to adjust the number of N output ports, and by adding or reducing the N output ports, M output ports are obtained.

[0072] S60: Charge the terminal device based on M output ports.

[0073] Wherein, after determining M output ports from N output ports, the terminal device can be charged through the M output ports. The M output ports can be in series or in parallel, and there is no specific limitation as long as the output parameters of the M output ports match the charging parameters of the terminal device.

[0074] In one embodiment, after step S60, the following operations are further performed:

[0075] Determine the real-time output voltage when charging the terminal device through the target output port and the reference voltage range of the target output port, wherein the target output port is any one of the M output ports;

[0076] Judge whether the real-time output voltage is within the reference voltage range;

[0077] If the real-time output voltage is not within the reference voltage range, send a second prompt message to prompt the user to replace the target output port with other output ports among the N output ports except the M output ports;

[0078] Adjust the output parameters of other output ports according to the output parameters of the target output port, and charge the terminal device based on the other output ports with adjusted output parameters.

[0079] In this embodiment, after the M output ports of the mobile power supply supply power to the terminal device simultaneously, it is necessary to detect the connection status between each output port in the M output ports and the terminal device, so as to determine whether the connection status between the M output ports and the terminal device is normal. First, determine the real-time output voltage when the target output port charges the terminal device and determine the reference voltage range of the target output port, and judge whether the real-time output voltage is within the reference voltage range. Secondly, when the real-time output voltage is not within the reference voltage range, it is determined that the target output port is damaged, and a second prompt message is sent to the user. The second prompt message instructs the user to replace the target output port with other output ports among the N output ports except the M output ports. Then, adjust the output parameters of the other output ports so that the output parameters of the other output ports are consistent with the output parameters of the target output port. Finally, charge the terminal device based on the other output ports after adjusting the output parameters.

[0080] It should be noted that, determine the real-time output voltage corresponding to each output port in the M output ports in turn. If the real-time output voltage of the output port is within the reference voltage range (the reference voltage range refers to the normal voltage output range allowed by the output port when the mobile power supply charges the terminal device through this output port), it is determined that the output port is in a normal connection state. If the real-time output voltage of the output port is not within the reference voltage range, it means that the output port is in an unconnected state or a damaged state. If the output port is in an unconnected state, prompt the user to detect whether the output port is loosely connected and instruct the user to connect the output port to the terminal device. If the output port is in a damaged state, replace the output port.

[0081] In one embodiment, step S60 includes:

[0082] If M is greater than or equal to 2, obtain the output voltage of each output port in the M output ports and the remaining power of each battery pack in the M battery packs corresponding to the M output ports;

[0083] Charge the terminal device according to the output voltage of each output port and the remaining power of each battery pack.

[0084] In this embodiment, each output port corresponds to a battery pack. When M is greater than or equal to 2, after obtaining the output voltage of each output port, also obtain the remaining power of the battery pack corresponding to the output port, and then charge the terminal device according to the output voltage of each output port and the remaining power of each battery pack. It should be noted that the output voltage of the corresponding output port can be adjusted according to the remaining power of the battery pack, so that the mobile power supply charges with the maximum power, which is beneficial to improving the power supply efficiency of the mobile power supply for the terminal device.

[0085] In one embodiment, charging the terminal device according to the output voltage of each output port and the remaining power of each battery pack includes:

[0086] Determining the output level of the remaining power of each battery pack;

[0087] Adjusting the output voltage of the M output ports according to the output level, and the adjusted output voltage of the M output ports matches the charging voltage in the charging parameters;

[0088] Charging the terminal device based on the adjusted output voltage of the M output ports.

[0089] In this embodiment, first, determine the output level of the remaining power of each battery pack. Different remaining powers represent different output levels. Second, adjust the output voltage of the M output ports according to the output level. The adjusted output voltage of the M output ports always matches the charging voltage of the charging parameters. Finally, charge the terminal device based on the adjusted output voltage of the M output ports. Please refer to Table 1. Table 1 is the mapping table of output levels and output voltages provided by the embodiments of the present application:

[0090] Table 1

[0091] Output level Remaining battery level Output voltage 1 81％～100％ 3.6～5v 2 51％～80％ 2.6～3.5v 3 21％～50％ 1.6～2.5v 4 0％～20％ 0～1.5v

[0092] As shown in Table 1, when the remaining power of the battery pack is more, the ranking of the output level is more forward, and the output voltage of the output port corresponding to the battery pack is also higher. For example, when there are Battery Pack A and Battery Pack B supplying power to the terminal device at the same time, where the remaining power of Battery Pack A is 78% and the remaining power of Battery Pack B is 45%. Referring to Table 1, the output level of Battery Pack A is 2, and the output level of Battery Pack B is 3. Adjust the output voltage of the output port corresponding to Battery Pack A and the output voltage of the output port corresponding to Battery Pack B for different levels. It can be seen from Table 1 that the output voltage of the output port corresponding to Battery Pack A is greater than the output voltage of the output port corresponding to Battery Pack B, so that the power consumption of Battery Pack A is faster than that of Battery Pack B, so as to achieve the purpose of Battery Pack A and Battery Pack B running out of power at the same time and maintaining the mobile power supply.

[0093] It should be noted that when the A battery pack and the B battery pack supply power to the terminal device, the remaining power of the A battery pack and the remaining power of the B battery pack are also detected in real time, and according to the corresponding mapping table, the output voltage of the output port corresponding to the A battery pack and the output voltage of the output port corresponding to the B battery pack are adjusted. For example, as the power supply time of the A battery pack and the B battery pack increases, when the output of the remaining power of the A battery pack tends to be the same as the remaining power of the B battery pack, the output voltage of the output port corresponding to the A battery pack and the output voltage of the output port corresponding to the B battery pack are adjusted to be the same.

[0094] It should be noted that the final output voltage of the mobile power supply is determined by the A output voltage and the B output voltage. If the A output voltage and the B output voltage cannot charge the terminal device with the optimal output voltage after adjustment, a prompt message can be sent. This prompt message is used to prompt the user to increase the connection ports between the mobile power supply and the terminal device. For example, the number of output ports is increased from the original 2 to 3, so as to ensure that the mobile power supply always charges the terminal device with the optimal output voltage.

[0095] In one embodiment, charging the terminal device according to the output voltage of each output port and the remaining power of each battery pack further includes:

[0096] Determine a second target difference between the remaining power of the target battery pack and a preset power threshold, where the target battery pack is any one of the M battery packs;

[0097] Adjust the output voltage of the output port corresponding to the target battery pack according to the second target difference;

[0098] Charge the terminal device based on the adjusted output voltage.

[0099] In this embodiment, determine a second target difference between the remaining power of the target battery pack and a preset power threshold. The preset power threshold is a value set in advance. For example, the preset power threshold is 10% of the rated charge capacity of the battery. If the second target difference is greater than the preset power threshold, the output voltage of the output port is adjusted according to the magnitude of the second target difference. Specifically, if the second target difference is relatively large, the output voltage of the target battery pack is increased; if the second target difference is relatively small, the output voltage of the target battery pack is decreased, so as to achieve the purpose of depleting the power of the M battery packs at the same time. Finally, the terminal device is charged based on the adjusted output voltage.

[0100] It should be noted that in order to protect the target battery pack, if the second target difference is less than or equal to the preset power threshold, the target battery pack enters a protection state, temporarily stops charging, and cuts off the connection between the target battery pack and the terminal device to protect the health of the battery.

[0101] Further, when the second target difference is less than or equal to the target battery pack, a warning message is sent. The warning message is used to instruct the user to replace the battery pack in a timely manner, replace the target battery pack with other battery packs except for the M battery packs, and adjust the output parameters of the other battery packs to continue powering the terminal device through the other battery packs, preventing the power supply efficiency of the mobile power supply to the terminal device from decreasing.

[0102] In one embodiment, charging the terminal device according to the output voltage of each output port and the remaining power of each battery pack further includes:

[0103] Determine whether there is a first battery pack with a remaining power less than a first preset threshold and a second battery pack with a remaining power greater than a second preset threshold among the M battery packs;

[0104] If so, disconnect the connection between the first battery pack and the first output port, and increase the output voltage of the second output port corresponding to the second battery pack, where the first output port is the output port among the M output ports connected to the first battery pack, and the second output port is the output port among the M output ports connected to the second battery pack;

[0105] Charge the terminal device based on the second output port with the increased output voltage.

[0106] In this embodiment, if there is a first battery pack with a remaining power less than the first preset threshold and a second battery pack with a remaining power greater than the second preset threshold among the M battery packs, first disconnect the connection between the first battery pack and the first output port. For example, the first preset threshold is 20% of the rated charge capacity of the battery, and the second preset threshold is 60% of the rated charge capacity of the battery. At this time, the remaining power difference between the first battery pack and the second battery pack is too large, and the first battery pack is in a nearly depleted state. First, disconnect the connection between the first battery pack and the first output port so that the first battery pack cannot power the terminal device, and then increase the output voltage of the second output port corresponding to the second battery pack so that the second output port with the increased output voltage meets the conditions for fast charging the terminal device, and charge the terminal device based on the second output port with the increased output voltage. If the output voltage of the increased second output port still cannot reach the most suitable charging voltage for the terminal device, a prompt message can be sent. The prompt message is used to prompt the user to increase the connection ports between the mobile power supply and the terminal device. For example, increase the number of output ports from the original 2 to 3. In this way, it can be ensured that the mobile power supply always charges the terminal device with the optimal output voltage.

[0107] It should be noted that the first battery pack and the second battery pack are two independent battery packs, and these two battery packs can supply power to the terminal device separately. For example, the first battery pack and the second battery pack are two battery packs within the same mobile power supply. It should be noted that the first battery pack and the second battery pack can be battery packs with the same battery pack parameters, or can be battery packs with different battery pack parameters. The power supply parameters can include the power supply voltage and / or the charging current, so as to provide the required voltage or current to the same terminal device.

[0108] In one embodiment, after charging the terminal device based on the second output port with the increased output voltage, the method further includes:

[0109] Real-time monitor the remaining power of the second battery pack;

[0110] If the remaining power of the second battery pack reaches the first preset threshold, connect the first battery pack to the first output port;

[0111] Reduce the output voltage of the second output port;

[0112] Charge the terminal device based on the second output port with the reduced output voltage and the first output port.

[0113] In this embodiment, when the second battery pack continuously supplies power to the terminal device, the remaining power of the second battery pack is also monitored in real time. When the remaining power of the second battery pack reaches the first preset threshold, for example, the remaining power of the second battery pack drops from 60% of the battery's rated charge capacity to 20% of the battery's rated charge capacity, and at this time the remaining power of the second battery pack is the same as that of the first battery pack, then connect the first battery pack to the first output port so that the first battery pack and the second battery pack supply power to the terminal device simultaneously. In order to make the first battery pack and the second battery pack tend to deplete their power at the same time, reduce the output voltage of the second output port corresponding to the second battery pack, and charge the terminal device based on the second output port with the reduced output voltage and the first output port.
