[0047] In some embodiments of an aspect of the invention, Figure 1 is an optional flow chart of the power supply adjustment method of the mobile power supply provided in the embodiment of the present application. Figure 1 The method may include but is not limited to including S100 to S400.

[0048] S100, the mobile power supply is connected to the device to be charged, and when the mobile power supply is in a discharging state, the current power supply mode of the mobile power supply is detected.

[0049] S200, obtaining a detection voltage output by each battery cell in the mobile power supply according to a set time interval, and determining a current battery voltage of each battery cell according to the detection voltage.

[0050] S300, obtaining a set discharge curve of each battery cell, and determining a current power supply stage of the mobile power source according to the current battery voltage and the set discharge curve.

[0051] S400, obtaining a current charging requirement sent by the charged device, and adjusting the power supply rate of each battery cell according to the current charging requirement and the current power supply stage to adjust the current power supply mode.

[0052] S100 to S400 shown in the embodiment of the present application determine the current power supply stage of the mobile power supply through the set discharge curve of each battery cell and the current battery voltage to accurately control the power supply state of the mobile power supply, and adjust the power supply rate of each battery cell through the supply and demand relationship between the current power supply stage and the current charging demand, thereby adjusting the power supply mode, balancing the charging process of the mobile power supply and the charged device, optimizing the charging speed, reducing unnecessary energy loss, and improving the energy conversion efficiency of the mobile power supply, so that the power of each battery cell can be more effectively utilized, improving the power supply efficiency and improving the user experience.

[0053] In S100 of some embodiments, the mobile power source is connected to the charged device, wherein the mobile power source may be connected by wire via a data cable or by wireless connection via electromagnetic induction.

[0054] Determine whether the current mobile power supply is in a discharging state, that is, determine whether the mobile power supply is charging the device being charged. If so, detect the current power supply mode of the mobile power supply. That is, detect the current power supply mode.

[0055] The current power supply mode includes: a fast power supply mode and a normal power supply mode.

[0056] In S200 of some embodiments, the mobile power supply generally includes a plurality of battery cells. The battery cell may be in the form of a single battery, or may be a battery pack composed of a plurality of batteries connected in series or in parallel. After a set time interval, the output voltage of each battery cell is detected by the detection circuit. That is, one battery cell corresponds to multiple sets of output voltage data.

[0057] For a battery cell, multiple groups of output voltage data are cleaned, abnormal voltage data are removed, and the average is taken to obtain the detection voltage of the current battery cell. Data processing is performed on each battery cell to obtain the detection voltage of each battery cell.

[0058] By detecting the voltage, the current battery voltage of each battery cell can be calculated based on the detection circuit.

[0059] For example, refer to Figure 2 The actual voltage of the battery cell is divided by the voltage-dividing resistors R1 and R2 to obtain the output voltage. The output voltage is obtained every 10 seconds until the sampling number is reached, and multiple sets of output voltage data are obtained. The multiple sets of data are processed to obtain the detection voltage.io And the voltage divider resistors R1, R2, U io =U i ×R1 / (R1+R2), calculate the actual voltage U of the battery cell i Among them, according to the number of battery cells in the mobile power supply and the specifications of the battery cells, the resistance values ​​of the voltage divider resistors R1 and R2 are adjusted to increase the detection voltage range of the detection circuit.

[0060] The time interval may be 10 seconds or 3 seconds. The time interval may be set according to actual conditions and is not limited in this embodiment.

[0061] In S300 of some embodiments, a discharge curve corresponding to each battery cell is obtained, wherein the discharge curve can represent the change of the voltage of the battery cell with time or discharge depth during the discharge process. The battery voltage is divided into voltage intervals on the discharge curve, and each voltage interval corresponds to a different SOC (State of Charge) range.

[0062] The current battery voltage is compared with the discharge curve to determine the current voltage range, so as to estimate the SOC range of the current battery cell.

[0063] Among them, the voltage range includes: full charge area, middle area and cut-off voltage area. The SOC range includes: full charge initial stage, discharge mid-stage and discharge end stage. The battery voltage at the beginning of full charge (100%-90% SOC) is higher, corresponding to the full charge area; the battery voltage at the end of discharge (5%-0% SOC) is lower, corresponding to the cut-off voltage area, and the battery voltage at the middle of discharge (89%-6% SOC) is between the beginning of full charge and the end of discharge, corresponding to the middle area.

[0064] The current power supply stage of the mobile power source, ie, the current power supply stage, is confirmed through the corresponding voltage interval or SOC range of each battery cell.

[0065] Among them, the current power supply stage includes: full charging power supply stage, mid-power supply stage and final power supply stage.

[0066] By judging the discharge state of each battery cell, the current power supply stage of the mobile power supply is determined to match the current charging demand, adjust the power supply rate, make full use of the energy of the battery cell, improve performance, and accurately control the power supply state of the mobile power supply.

[0067] In S400 of some embodiments, the charged device sends the current charging demand, and according to the supply-demand relationship between the current charging demand and the power supply state of the mobile power source, the power supply rate of each battery cell is adjusted, thereby adjusting the power supply mode of the mobile power source.

[0068] The current charging demand includes: the current power of the device being charged and the charging specification parameters of the device being charged.

[0069] In some embodiments of an aspect of the present invention, S300, the process of determining the current power supply stage specifically includes:

[0070] S310, judging whether the current battery cell enters a cut-off voltage region on a set discharge curve according to the current battery voltage.

[0071] S311, if yes, determine that the current battery cell is at the end of discharge, and detect the running number of battery cells at the end of discharge.

[0072] S312: When the running quantity is greater than the set quantity, it is considered that the current power supply stage is the final power supply stage.

[0073] In this embodiment, the current battery voltage is compared with the discharge curve of the current battery cell to determine whether the voltage interval of the current battery voltage on the discharge curve is a cut-off voltage region.

[0074] If the current battery voltage is in the cut-off voltage region, it is considered that the current battery cell is in the final stage of discharge (5%-0% SOC).

[0075] Traverse each battery cell and determine the number of battery cells at the end of discharge, that is, the running number. Determine whether the running number is greater than the set number. If so, it is considered that the current mobile power supply is at the end of the power supply stage and cannot meet the charging needs of the charged device.

[0076] That is to say, when the current battery voltages of the set number of battery cells are all in the cut-off voltage area, it is considered that the charging demand of the charged device cannot be met, the current mobile power supply is in the final power supply stage, the current mobile power supply stops supplying power to the charged device, and sends out a warning signal.

[0077] The specific numerical value of the set quantity can be set according to actual application and is not specifically limited in this embodiment.

[0078] In some embodiments of one aspect of the present invention, S300, the process of determining the current power supply stage specifically further includes:

[0079] S320: Determine, based on the current battery voltage, whether the current battery cell is in a full charge region on a set discharge curve.

[0080] S321, if yes, determine that the current battery cell is in the initial stage of full charge, and judge whether each battery cell is in the initial stage of full charge.

[0081] S322: When each battery cell is in the initial stage of full charge, it is considered that the current power supply stage is the full charge power supply stage.

[0082] In this embodiment, the current battery voltage is compared with the discharge curve of the current battery cell to determine whether the voltage interval of the current battery voltage on the discharge curve is a full charge area.

[0083] If the current battery voltage is in the full charge region, it is considered that the current battery cell is in the initial stage of full charge (100%-90% SOC).

[0084] Traverse each battery cell and determine the number of battery cells in the initial stage of full charge. Determine whether this number is the reserve of all battery cells on the mobile power supply. If so, it is considered that the current mobile power supply is in the full charge power supply stage and can meet the charging needs of the charged device.

[0085] That is to say, when the current battery voltage of all battery cells is in the full charge area, it is considered that the charging demand of the charged device can be met. The current mobile power supply is in the full charge power supply stage, and provides corresponding power supply rates for different charging demands of the charged device.

[0086] In some embodiments of one aspect of the present invention, S300, the process of determining the current power supply stage specifically further includes:

[0087] S330, judging whether the current battery cell is between the full charge region and the cut-off voltage region on the set discharge curve according to the current battery voltage.

[0088] S331, if yes, determine that the current battery cell is in the middle of discharge, and judge whether each battery cell is in the middle of discharge.

[0089] S332: When each battery cell is in the middle stage of discharge, it is considered that the current power supply stage is the middle stage of power supply.

[0090] In this embodiment, the current battery voltage is compared with the discharge curve of the current battery cell to determine whether the voltage interval of the current battery voltage on the discharge curve is in the middle area, that is, between the full charge area and the cut-off voltage area.

[0091] If the current battery voltage is in the middle region, it is considered that the current battery cell is in the middle of discharge (89%-6% SOC).

[0092] Traverse each battery cell and determine the number of battery cells in the middle of discharge. Determine whether this number is the reserve of all battery cells on the mobile power supply. If so, it is considered that the current mobile power supply is in the middle of power supply stage and can meet most of the charging needs of the charged device.

[0093] That is to say, when the current battery voltage of all battery cells is in the middle area, it is considered that the charging needs of the charged device can be mostly met. The current mobile power supply is in the middle power supply stage, providing corresponding power supply rates for different charging needs of the charged device.

[0094] In some embodiments of one aspect of the present invention, S400, the adjustment process specifically includes:

[0095] S410, when the current power supply stage is the full charge power supply stage and the current charging demand is a high demand, the power supply rate of each battery cell is adjusted, and the current power supply mode is adjusted to a fast power supply mode, so that the mobile power supply supplies power to the charged device at the set first power supply rate until entering the final power supply stage.

[0096] In this embodiment, if the current state is the full charge power supply stage, that is, each battery cell is in the initial stage of full charge (100%-90% SOC), the mobile power supply can meet the charging demand of the charged device.

[0097] When the mobile power supply is in the full charging stage and the current charging demand is high, that is, the charged device needs to be quickly replenished to prevent shutdown, and the mobile power supply has sufficient power, the current power supply mode is adjusted to the fast power supply mode, and the power supply rate of each battery cell is adjusted. The mobile power supply supplies power to the charged device according to the set first power supply rate.

[0098] Since the power bank has limited power, under high charging demand, it may not be able to fully cover the power of the charged device. In this case, the power bank will supply power to the charged device until the end of the power supply period.

[0099] The current charging demand includes: the current power of the device being charged and the charging specification parameters of the device being charged. The current power is inversely proportional to the charging demand, that is, the lower the current power of the device being charged, the higher its charging demand.

[0100] Exemplarily, when the current power level of the charged device is less than the set high demand threshold, it is considered that the charging demand of the charged device is high demand.

[0101] S420, when the current power supply stage is the middle power supply stage and the current charging demand is high demand, the power supply rate of each battery cell is adjusted, and the current power supply mode is adjusted to the fast power supply mode, so that the mobile power supply supplies power to the charged device at the set second power supply rate until entering the final power supply stage.

[0102] In this embodiment, if the current power supply is in the middle stage, that is, each battery cell is in the middle stage of discharge (89%-6% SOC), the mobile power supply can meet most of the charging requirements of the charged device.

[0103] When the mobile power supply is in the mid-stage of power supply, when the current charging demand is high, that is, the charged device needs to be quickly replenished to prevent shutdown, and the mobile power supply has a certain amount of power, the current power supply mode is adjusted to the fast power supply mode, and the power supply rate of each battery cell is adjusted. The mobile power supply supplies power to the charged device according to the set second power supply rate.

[0104] Since the power in the middle stage of power supply is lower than the power in the full charge stage, under high charging demand, the current power supply mode is still adjusted to the fast power supply mode, and the power supply rate of each battery cell is adjusted. The mobile power supply supplies power to the charged device according to the set second power supply rate, which is lower than the first power supply rate. The power supply is divided into power supply stages to adapt to the battery state changes of the battery cells, ensure that each battery cell in the mobile power supply is balanced, and prevent over-discharge, until the mobile power supply supplies power to the charged device until it enters the final stage of power supply.

[0105] S430, when the current power supply stage is the mid-power supply stage and the current charging demand is low demand, or when the current power supply stage is the full-charge power supply stage and the current charging demand is low demand.

[0106] S431, adjusting the power supply rate of each battery cell, adjusting the current power supply mode to the normal power supply mode, so that the mobile power supply supplies power to the charged device at the set third power supply rate.

[0107] In this embodiment, if the current charging demand is a low demand, the current power supply stage is a mid-power supply stage or a full-charge power supply stage, and it is considered that the mobile power supply can meet the charging demand of the charged device.

[0108] On the premise that the mobile power supply can provide enough power, when the current charging demand is low, that is, the charged device has a certain amount of power and does not need to be fully charged quickly, and the mobile power supply has a certain amount of power, then in order to extend the service life of the batteries of the mobile power supply and the charged device, the current power supply mode is adjusted to the normal power supply mode, and the power supply rate of each battery cell is adjusted. The mobile power supply supplies power to the charged device at a set third power supply rate, which is lower than the second power supply rate, so as to lower the charging temperature and reduce the battery cycle pressure.

[0109] In addition, since the mobile power supply has a certain amount of power and the charged device has low demand, it can be considered that the power of the mobile power supply is sufficient to supply the charged device, and there is no need to cut off the power supply in the final stage of power supply as in high demand adjustment.

[0110] Exemplarily, when the current power level of the charged device is greater than the set low demand threshold, it is considered that the charging demand of the charged device is low demand.

[0111] The embodiment of the present application also provides a power supply regulation system of a mobile power source, which can implement the power supply regulation method of the mobile power source mentioned above. The device includes: a mode detection module, a voltage detection module, a first regulation module and a second regulation module.

[0112] The mode detection module is used to connect the mobile power supply to the charged device, and when the mobile power supply is in a discharging state, the current power supply mode of the mobile power supply is detected;

[0113] The voltage detection module is used to obtain the detection voltage output by each battery cell in the mobile power supply according to a set time interval, and determine the current battery voltage of each battery cell according to the detection voltage;

[0114] The first regulating module is used to obtain a set discharge curve of each of the battery cells, and determine the current power supply stage of the mobile power source according to the current battery voltage and the set discharge curve;

[0115] The second regulating module is used to obtain the current charging demand sent by the charged device, and adjust the power supply rate of each battery cell according to the current charging demand and the current power supply stage to adjust the current power supply mode.
