However, traditional mobile power supplies have a slow charging speed, and the emerging fast charging technology will cause the battery to heat up quickly and lose power quickly, which will shorten the life of the mobile power supply, increase the charging loss, and make its capacity unable to reach the rated capacity.

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] The present application embodiment discloses a charging method for a mobile power source capable of rapid charging. Figure 1The charging method of the mobile power source capable of fast charging comprises the following steps: S1, obtaining device parameters, obtaining charging connection signals, the device parameters including charging protocol data, obtaining mobile terminal power data; S11, determining matching charging power data through charging protocol data, charging connection signals and preset mobile charging thresholds; S12, determining and outputting charging power data by matching charging power data, mobile terminal power data and a preset fast charging scheme threshold; S13, receiving fast charging signal; S14. Determine the charging power data through the fast charging signal and matching the charging power data and output it.

[0037] In detail: the device parameters are the data of the device to be charged, including the device model, the rated charging current, rated voltage, rated power, charging protocol data, etc. that can be received. The charging connection signal is the detection of an external device being plugged in to prepare for charging. The mobile terminal power data is the remaining power of the external device. The charging protocol data is the range of the allowed charging power that the external device can receive, including the range of rated voltage, the range of rated current, and the range of rated power. The mobile charging threshold is the range of charging output supported by the battery. For example, if the charging connection signal is the detection of the device being electrically connected, the charging protocol data is set to [5W, 40W], and the mobile charging threshold is set to [1W, 66W]. Then, it can be obtained that the battery can support all the charging ranges allowed by the external device at this time, and the matching charging power data is [5W, 40W]. In this embodiment, for ease of understanding, the threshold is obtained by table lookup, and in other embodiments, it can also be calculated by relational expressions. In the subsequent steps, the same is true. Suppose the fast charging solution is (3 0%, 100%), (80%, 90%), (95%, 50%), which means that when the power data on the mobile terminal is 30%, the battery is allowed to charge at a charging threshold of 100%, that is, the maximum is 66W. When the power data on the mobile terminal is 80%, the battery is allowed to charge at a charging threshold of 90%, that is, the maximum is 66*90%=59.4W. When the power data on the mobile terminal is 95%, the battery is allowed to charge at a charging threshold of 50%, that is, the maximum is 6 6*50%=33W. If the power data on the mobile terminal is 95%, that is, only 95% of the power remains, the maximum allowed battery is charged at a charging power of 33W. Combined with the matching charging power data, that is, the intersection of [0.5W, 33W] and [5W, 40W], the maximum charging power data can be obtained as 33W, so the maximum output is 33W. If a fast charging signal is received, the fast charging solution is ignored, and the charging power data is directly obtained and output according to the maximum power of the matching charging power data.

[0038] Reference Figure 2, the fast charging solution includes the following steps: S2, obtaining power supply data, outputting and displaying the power supply data; S21, determining charging mode data based on mobile terminal power data and a preset fast charging stage threshold; S22, determining charging efficiency data based on power supply data and a preset charging efficiency threshold; S23, determining a power ratio by using the mobile terminal power data and the power source power data; S24, determining a conversion coefficient by comparing the power ratio and a preset power ratio threshold; S25, determining a charging coefficient through the charging mode data, the charging efficiency data and the conversion coefficient; S26. Determine the charging power data by matching the charging coefficient with the charging power data and output it.

[0039] Detailed: The power data is the remaining power of the battery itself, which is displayed by a display device such as an LCD screen, an electronic screen, a digital screen or multiple LED lamps. The fast charging stage threshold is set to (30%, 100%), (80%, 90%), (95%, 50%), and the charging mode data can be obtained by substituting the mobile terminal power. For example, if the mobile terminal power is 30%, the charging mode data is 100%. The charging efficiency threshold is set to (30%, 80%), (60%, 60%), (90%, 50%), that is, It means that when the power data is 30%, that is, when the power is running low, 80% charging efficiency is required, that is, when the power output is 1000mah, the power data of the mobile terminal needs to increase by at least 800mah to reduce the loss caused by heating, that is, reduce the charging current and reduce heat generation. When the power data is 90%, only 50% charging efficiency is required, that is, when the power output is 1000mah, the power data of the mobile terminal needs to increase by at least 500mah to allow more Fast charging speed; if the power data of the mobile terminal is 30% and the power data of the power supply is 60%, the power ratio can be obtained as 0.3 / 0.6=0.5. Generally speaking, the smaller the power ratio is, the lower the power of the device to be charged is, and the higher the power of the power supply is, the higher the charging power can be allowed to charge. If the power ratio threshold is (0.1, 100%, 0%), (0.5, 50%, 50%), it means that when the power ratio is 0.5, the conversion coefficients of 50% and 50% can be obtained by substituting the power ratio. Substituting the charging method data and charging efficiency data, we can get a charging coefficient of 100%*50%+60%*50%=80%. Multiplying this 80% by the matching charging power will give the corrected charging power data. In simple terms, when the battery is full, a certain degree of loss is allowed, and the device is charged directly based on the maximum charging power output that the external device can receive. However, if the battery is low and the user does not input a fast charging signal, excessive loss is not allowed, and the external device must match the charging power of the battery.

[0040] Reference Figure 3 , the fast charging solution also includes the following steps: S3, obtaining charging current data and charging voltage data; S31, determining actual power data through charging current data and charging voltage data; S32, determining an error value through actual power data and charging power data; S33: Determine new charging power data based on the error value and a preset error adjustment threshold and output it.

[0041] In detail: the charging current data is the current detected when the battery itself charges the external device, and the charging voltage data is the voltage detected when the battery itself charges the external device. It is usually obtained by directly collecting the current and voltage at the external output end of the battery itself. The actual power can be obtained by multiplying the charging current data by the charging voltage data, that is, the actual power data P=U*I. The actual power data detected is compared with the charging power data obtained by theoretical calculation to obtain the error value. The error value may be caused by the increase of internal resistance or the existence of magnetic induction. This means that the processor outputs the charging power data signal to control the output current and voltage, and the error value between the actual output current and voltage exists in the conversion of digital electricity into analog electricity. Then the processor adjusts and corrects the original charging power data according to the error value through the calculation of the error adjustment threshold, obtains the new charging power data and outputs the control, so that the actual charging power is closer to the theoretical charging power.

[0042] Reference Figure 4 , the fast charging solution also includes the following steps: S4, obtaining temperature detection data; S41, determining a loss coefficient through temperature detection data, charging current data and a preset loss threshold; S42, determining charging conversion efficiency data by using a loss coefficient and a preset loss stage threshold; S43, determining a charging coefficient through the charging mode data, the charging efficiency data, the conversion coefficient and the charging conversion efficiency data; S44. Determine and output an emergency stop signal based on the temperature detection data and the preset alarm temperature threshold.

[0043] Detailed: The temperature detection data is the data directly obtained by detecting the battery, for example, the temperature is obtained by detecting the battery surface with a temperature sensor or inserting the battery to detect the temperature of the battery cell. Assume that the loss threshold is (40°, (bI) / b), I is the charging current data, b is the current without loss in the ideal state when it is just out of the factory and not working, 40° is the temperature detection data for example, indicating that at 40°, the current without loss is b, b changes with the change of temperature, and the current reduction caused by loss is bI, a is the coefficient, and the loss coefficient can be obtained as a*( bI), which means that the increase in internal resistance due to extended use time and increased internal resistance caused by increased temperature will lead to current loss. Combined with the loss stage threshold, the charging conversion efficiency threshold can be obtained. Simply put, if b is 2A at 40°, and the actual charging current data is 1.8A, the loss coefficient can be obtained as 0.2 / 2=10%. At this time, the charging conversion efficiency data is 1-10%=90%, which means that the electric energy in the battery can be charged into the external device with an efficiency of 90%. The charging conversion efficiency data is used to participate in the calculation of the charging coefficient in step S25. The original charging coefficient is corrected. For example, the original charging mode data with the external device is the charging power received by the external device. However, there is a conversion efficiency from the battery output to the external device. That is, if calculated according to the original charging power, the charging power of the external device will be less. For example, the battery is full, but the power of the external device is less, that is, the battery can output at the maximum power. At this time, if the charging mode data is 90%, the battery outputs at 90% of the charging power. The battery does output electrical energy at 90% of the charging power, but the electrical energy actually entering the external device can only be 90%*90%=81% of the charging power is used to charge the external device, and the 9% difference in the middle is lost in the internal resistance. Therefore, if the charging mode data needs to reach 90% at this time, the battery needs to output a charging power of 100%. At this time, 100%*90%=90% can achieve 90% of the charging mode data to charge the external device; if the temperature detection data exceeds the range of the alarm temperature threshold, for example, the temperature detection data is 70° and the alarm temperature threshold is 70°, the processor will output an emergency stop signal to stop the battery output charging to achieve cooling.

[0044] Reference Figure 5 , further comprising the following steps: S5, obtaining time data, device parameters including internal resistance threshold; S51, determining equivalent internal resistance data through charging current data and charging voltage data; S52, determining heating data through equivalent internal resistance data, charging current data and internal resistance threshold; S53, determining temperature change data through temperature detection data and time data; S54, determining fever change data through the fever data and the time data; S55, determining internal temperature data through temperature change data and heating change data; S56. Replace the temperature detection data with the internal temperature data to determine the loss coefficient with the loss threshold to participate in the calculation of the charging coefficient.

[0045] In detail: R=U / I, where R is the equivalent internal resistance data, R is the calculated equivalent internal resistance, not the internal resistance at the time of leaving the factory. The equivalent internal resistance includes the part of the internal resistance increased due to temperature rise, and the internal resistance threshold is the cross-sectional area of ​​the internal resistance and other parameters related to the heat generated after the current passes through. This data is determined at the factory and will not change due to temperature rise. At this time, the detected charging current data and the calculated equivalent internal resistance data are combined with the fixed internal resistance threshold to obtain the heat generated by the internal resistance at this time, which is the heat generation data. Combined with the time data, the heat generated by the internal resistance over time can be obtained, and the temperature detection data directly collected indicates the temperature outside the battery, and the heat outside the battery is the heat dissipated. Combined with the time data, the heat dissipated by the battery can be obtained, which is the temperature change data. The heat change data minus the temperature change data is the heat remaining inside the battery that has not been dissipated, which is the internal temperature data, which is the heat inside the internal resistance. The internal temperature data replaces the temperature detection data in step S41 to obtain a more accurate internal resistance loss.

[0046] Reference Figure 6 , further comprising the following steps: S6. Determine the device internal resistance data through the internal temperature data, the charging current data, the charging voltage data and the preset temperature internal resistance threshold; S61, determining the device current and the device voltage through the charging current data, the charging voltage data and the device internal resistance data; S62, determining device power data through device current and device voltage; S63. Determine new charging power data based on the device power data and the charging power data and output it.

[0047] Detailed: The temperature internal resistance threshold indicates the approximate internal resistance at the current temperature. For example, the initial factory resistance is c, and the internal resistance of the current model is affected by temperature by a coefficient of d. If the temperature is t, the internal resistance increase caused by temperature t is t*d, and the total resistance is t*d+c. Therefore, the total resistance can be deduced from temperature t as t*d+c. At this time, the resistance of the battery and the battery output can be obtained. This resistance does not include external devices, that is, it does not include the external load of the battery. However, during the charging process, the charging current data and the charging voltage data are affected by the external load of the external device. If the battery is charged with a constant current, the theoretical charging voltage data can be obtained as I*(t*d+c), and the difference between the actually detected charging voltage data and I*(t*d+c) is the impact, and based on The equivalent resistance data obtained from the actual detected charging voltage data and charging current data minus I*(t*d+c) is the resistance of the external load of the external device, that is, the internal resistance data of the device. At this time, the resistance of the external load multiplied by the charging current data is the device voltage. When the battery is charged with a constant current, the detected charging current data is the device current. If it is charged with a constant voltage, the charging voltage data is the device voltage, and then the device current is calculated; then the device current is multiplied by the device voltage to obtain the device power data, which is actually the charging power received by the external device on the battery. By comparing this with the charging power data, the difference between the charging power output by the battery and the charging power received by the external device can be obtained, thereby adjusting the charging power output by the battery to obtain new charging power data.

[0048] Reference Figure 7 , further comprising the following steps: S7. Determine the proportionality coefficient based on the charging power data and the equivalent internal resistance data; S71, determining life data through a proportional coefficient and a preset proportional life threshold and outputting the data; S72, determining temperature-rise internal resistance data through internal temperature data, charging current data and a preset temperature-rise internal resistance threshold; S73, determining the internal resistance data to be used through the equivalent internal resistance data and the temperature rise internal resistance data; S74 , determining life data by using the internal resistance data and a preset life threshold value and outputting the life data.

[0049] In detail: the shorter the usage time, the lower the loss, that is, the smaller the increase in internal resistance due to use. If the battery is charged with constant power output, if the charging voltage data is e, let the equivalent internal resistance data be f, and the charging power data be g, and as the usage time increases, the equivalent internal resistance data continues to rise, that is, f will become larger and larger, and since the battery has a constant power output, if the charging voltage data is still maintained at e, the corresponding current U / R will become smaller and smaller, that is, g will become smaller and smaller, so if g needs to be kept unchanged, the output voltage will be continuously increased. Therefore, the longer the battery is used, in order to ensure the same power output, a higher temperature rise will be generated, that is, when the charging power data is the same, there will be a higher equivalent internal resistance data. If the proportionality coefficient is charging power data / equivalent internal resistance data, then The coefficient will become smaller and smaller, and then combined with the proportional life threshold to look up the table, you can get the approximate life data and output it to the user for viewing; the temperature generated by the equivalent internal resistance is T=(R1+R2+R3)*A*I, R1 is the internal resistance at the factory, which can be directly queried in the product parameters, R2 is the internal resistance that increases with the use time, R3 is the internal resistance caused by temperature rise, A is the coefficient of temperature rise caused by the internal resistance under the influence of current, that is, the internal resistance threshold, I is the charging current data, so R3 can be calculated, which is the temperature rise internal resistance data, and then the equivalent internal resistance data minus R1 minus R3 can get R2, which is the use internal resistance data, combined with the life threshold to determine the service life of the internal resistance, that is, the life data, of the two life data, whichever represents the longer used life will be displayed.
