[0023] Please refer to Figure 1 , which shows a flow chart of an embodiment of a charging control method according to the present disclosure. The charging control method can be applied to a power supply device, which can read the voltage value of a target power source and control the voltage value output to the target power source. Figure 1 The charging control method shown comprises the following steps:

[0024] Step 101, in response to detecting a first power transmission instruction, supplying power to an over-discharged target power source, and detecting a fluctuation value of a voltage value of the target power source within a first preset time period.

[0025] Here, within the first preset time length, the target power supply voltage value within the first preset time length can be detected multiple times, so as to determine the fluctuation value of the target power supply voltage value within the first preset time length. Of course, within the first preset time length, the specific number of times the power supply voltage value is detected can be set according to actual conditions, for example, the voltage value of the power supply voltage can be detected in real time.

[0026] As an example, the fluctuation value may be understood as: a difference between a minimum voltage value of the target power source and a maximum voltage value of the target power source within a first preset time period.

[0027] Here, the target power source may be an over-discharged power source.

[0028] As an example, when the over-discharged target power source needs to be charged, the power supply device can be connected to the target power source, and then the first power transmission instruction can be generated. Correspondingly, the power supply device can supply power to the target power source at this time.

[0029] As an example, when supplying power to the target power source, a current smaller than the target power source's normal discharge current may be used for supplying power. Of course, the specific current used for supplying power may be set according to actual conditions.

[0030] Step 102: Determine whether the target power source corresponds to an over-discharge protection circuit according to the detected fluctuation value.

[0031] Here, the over-discharge protection circuit is used to interrupt the connection between the target power supply and the external power-consuming device when the target power supply voltage value is lower than the first preset voltage value. In this way, the target power supply can be prevented from continuing to supply power to the external power-consuming device, thereby preventing the target power supply from suffering excessive damage.

[0032] While charging the power supply, the impedance of the over-discharge protection circuit will increase instantaneously, and the voltage value of the power supply will increase instantaneously. However, as charging progresses, the amount of electricity inside the power supply gradually increases, and the impedance of the over-discharge protection circuit will gradually decrease. At this time, the over-discharge protection circuit can be understood as a wire; accordingly, the target power supply can be powered normally at this time.

[0033] At the same time, when the power supply is charged normally, the voltage of the target power supply will slowly rise as the charging process proceeds; if the power supply contains an over-discharge protection circuit, during the charging process, due to the presence of transistors, capacitors and other devices in the protection circuit, the power supply voltage of the target power supply will fluctuate more seriously.

[0034] That is, due to the function of the over-discharge protection circuit, when the over-discharge power source including the over-discharge protection circuit is charged, the over-discharge protection circuit will generate a large impedance, so that the voltage value of the target power source will suddenly increase.

[0035] For ease of understanding, you can combine Figure 2 To explain, Figure 2 It can be understood as a schematic diagram of the change in power supply voltage when a power supply with an over-discharge protection circuit is connected to a power supply device. Figure 2 It can be seen that after the power supply device is connected, if the over-discharge power supply includes an over-discharge protection circuit, the duration of the t1-t2 time period can be 1 second or several seconds. It can be seen that the power supply voltage will instantly soar from a low voltage to a high voltage. In the time period t1-t2, the power supply voltage will soar in a short period of time, which may be caused by the target power supply having a power protection circuit.

[0036] It should be noted that in order to protect the battery, when charging the power supply, it is usually charged with a small current first, and then with a larger current. It should be noted that the comparison objects of small and large here can be understood as the discharge current value of the target power supply. That is, the specific current used for charging needs to be reasonably set according to the actual power supply situation.

[0037] Step 103 , in response to determining that the target power source corresponds to the over-discharge protection circuit, adjusting the supply voltage to the target voltage value, and turning off the charge monitoring circuit corresponding to the target power source.

[0038] Here, the charging monitoring circuit can be used to interrupt the connection between the power supply device and the target power supply when the voltage value of the target power supply exceeds a second preset voltage value.

[0039] As an example, the second preset voltage value may be understood as: a charging cut-off voltage value of the target power source.

[0040] As an example, in order to prevent overcharging, the power supply is usually equipped with a charging monitoring circuit. When it is detected that the power supply is fully charged, the charging process can be interrupted, thereby effectively preventing overcharging. In general, the charging monitoring circuit can determine the charging process by judging the power supply current and power supply voltage. If the power supply voltage is greater than or equal to the maximum value of the power supply voltage (this voltage value can be understood as the charging cut-off voltage value), it can be indicated that the power supply is fully charged. If the power supply current is less than the predefined current value, it can also indicate that the power supply is fully charged.

[0041] In the related art, when charging an over-discharged power supply, it is usually charged directly. However, when the over-discharged power supply has an over-discharge protection circuit, the impedance of the over-discharge protection circuit will be very large, so the power supply voltage will have an instantaneous high voltage. At this time, the charging monitoring circuit can determine that the power supply has been charged, and the connection between the power supply and the power supply device can be interrupted, thereby terminating the charging. It can be seen that this method cannot realize the charging of an over-discharged power supply with an over-discharge protection circuit.

[0042] In the present disclosure, when the first power transmission instruction is detected, power can be supplied to the target power supply, and the fluctuation value of the target power supply voltage value within the first preset time period can be detected, and whether the target power supply has an over-discharge protection circuit can be determined based on the fluctuation value; when it is determined that the target power supply has an over-discharge protection circuit, the supply voltage can be adjusted to the target voltage value, and the charging monitoring circuit corresponding to the target power supply can be turned off. In this way, the supply voltage can continuously output a high voltage to activate the target power supply, which increases the probability of activating the target power supply with a protection circuit.

[0043] In the related art, when charging an over-discharged power supply, the charging monitoring circuit will not be turned off. Therefore, when charging the over-discharged power supply, since the charging monitoring circuit is always monitoring the power supply voltage and current, the transmission between the power supply device and the power supply is interrupted when charging starts, and the over-discharged power supply cannot be charged.

[0044] In some embodiments, step 102 (determining whether the target power supply has an over-discharge protection circuit according to the detected fluctuation value) may specifically include:

[0045] Whether the target power supply has an over-discharge protection circuit can be determined based on the size of the fluctuation value.

[0046] As an example, if the target power supply does not have an over-discharge protection circuit, the power supply voltage value of the target power supply gradually increases during the charging process; that is, the power supply voltage value will not fluctuate greatly. If the target power supply has an over-discharge protection circuit, the power supply voltage will fluctuate greatly during the charging process due to the effect of the over-discharge protection circuit.

[0047] As an example, a fluctuation threshold may be set, that is, when the fluctuation value is greater than the fluctuation threshold, it may be determined that the target power supply has an over-discharge protection circuit. Of course, the specific value of the fluctuation threshold may be limited according to actual conditions.

[0048] Correspondingly, when the fluctuation value is less than the fluctuation threshold, it can be characterized that the target power supply does not have an over-discharge protection circuit. At this time, the power supply voltage of the target power supply gradually increases, and when the power supply voltage of the target power supply increases to the discharge cut-off voltage of the target power supply, the normal charging process can be entered.

[0049] In some embodiments, in step 103, "in response to determining that the target power source corresponds to an over-discharge protection circuit, adjusting the supply voltage to a target voltage value" may specifically include: determining the target voltage value according to a full-power voltage value corresponding to the target power source.

[0050] Here, the target voltage value is not less than the full-charge voltage value.

[0051] As an example, adjusting the supply voltage to a target voltage value may allow the target voltage value to continue to be used to activate the power source; thereby making it more likely that the target power source will be activated.

[0052] As an example, the target voltage value may be 1.2 times the full-power voltage value of the target power source. Of course, in a specific embodiment, the specific values ​​of the target voltage value and the full-power voltage value may be determined according to actual conditions.

[0053] In some embodiments, the voltage value of the target power source may be detected at least twice within the second preset time period; and whether to adjust the supply voltage may be determined based on the voltage values ​​of the target power source detected at least twice.

[0054] Here, within the second preset time period, the supply voltage can be maintained at the target voltage value.

[0055] As an example, when it is detected that the target power supply has an over-discharge protection circuit, the supply voltage can be adjusted to the target voltage value, and the supply voltage can be maintained at the target voltage value for a second preset time. In this way, it is convenient to activate the target power supply (a stronger voltage can be applied to the target power supply); at the same time, it is also convenient to reduce the impedance of the over-discharge protection circuit.

[0056] It should be noted that when a larger voltage (which can be understood as an activation voltage) is applied to the target power supply, the impedance of the over-discharge protection circuit will gradually decrease.

[0057] As an example, within the second preset time period, the specific number of times the voltage value of the target power source is detected can be limited according to actual conditions, and the specific number of times the voltage value of the target power source is detected is not limited herein.

[0058] In some embodiments, determining whether to adjust the supply voltage based on the voltage values ​​of the target power source detected at least twice may specifically include:

[0059] In response to detecting that the later detected voltage value is not greater than the earlier detected voltage value, it is determined whether to adjust the supply voltage based on a voltage difference between the first voltage value and the third preset voltage value.

[0060] Here, the third preset voltage value may be used to indicate a discharge termination voltage of the target power source.

[0061] Here, the first voltage value is a voltage value detected last time in at least two detections.

[0062] As an example, in the process of using a large voltage to activate the target power supply, since the target power supply is an over-discharged power supply, the initial voltage value of the target power supply is too small. Therefore, as time goes by, the voltage value of the target power supply will gradually decrease. When the voltage value of the target power supply decreases to near the third preset voltage value, if it does not continue to decrease at this time, it can be characterized that the target power supply has been activated. At this time, the supply voltage can be adjusted so that the battery can be charged normally, so as to reduce the loss of the battery during the charging process and save the battery life.

[0063] For ease of understanding, you can combine Figure 3 To explain, Figure 3 It can be understood that the target power supply is in the process of power activation. Figure 3 In the figure, V1 can be understood as the power supply voltage value of the target power supply after the power supply is over-discharged, V2 can be understood as the power supply voltage value after the target power supply is normally discharged, and V3 can be understood as the maximum value to which the power supply voltage soars due to the impedance of the over-discharge protection circuit when the over-discharged power supply is activated. Figure 3It can also be seen that in the time period t1-t2, the power supply voltage can soar to the maximum value, and in the time period t3-t4, the power supply voltage is fluctuating (at this time, due to the effect of the transistor in the over-discharge protection circuit, the power supply voltage will fluctuate). In the time period t4-t5, the power supply voltage will gradually decrease to a normal discharge voltage near V2. At this time, it can be indicated that the normal charging process has begun, that is, it can be indicated that the activation of the target power supply is successful at this time. It can be understood that if the power supply voltage of the target power supply gradually decreases and tends to a fixed voltage value ( Figure 3 The voltage value corresponding to the dotted line can be understood as a fixed value), which can indicate that the target power supply is activated successfully; correspondingly, if the voltage value that the power supply voltage of the target power supply finally tends to is less than the third preset voltage value, it can also indicate that the target power supply activation fails.

[0064] At the same time, from Figure 3 It can be seen that the time interval from V1 to V3 is short, that is, in the process of activating the power supply, the power supply voltage will soar from the over-discharge discharge voltage value to the maximum voltage value in a short time, and maintain at the maximum value. Then, due to the action of the over-discharge protection circuit, there may be a short-term fluctuation in the power supply voltage. After that, the power supply voltage may gradually decrease and tend to a stable voltage value (if the voltage value is not less than V2, it can be indicated that the activation of the target power supply is successful), and then the normal charging process can be entered.

[0065] In some embodiments, the voltage difference between the first voltage value and the third preset voltage value determines whether to adjust the supply voltage, which may specifically include: in response to determining that the voltage difference is not greater than a preset threshold and the first voltage value is not less than the third preset voltage value, the supply voltage may be adjusted according to the first voltage value.

[0066] As an example, if the voltage difference is not greater than the preset threshold value, and the first voltage value is not less than the third preset voltage value, it can be indicated that the power supply voltage has dropped to near the third preset voltage value, and thus it can be indicated that the target power supply can be powered normally at this time, therefore, the power supply voltage can be adjusted according to the first voltage value at this time. In this way, it is possible to avoid a large voltage acting on the target power supply and damaging the target power supply.

[0067] It should be noted that when the voltage value of the target power source is higher than the third preset voltage value and enters the normal charging process, the impedance of the over-discharge protection circuit is low at this time, so it will not interfere with the normal charging process.

[0068] In some embodiments, after adjusting the supply voltage according to the voltage value detected last time, the charging monitoring circuit may be turned on.

[0069] As an example, after the supply voltage is adjusted according to the last detected voltage value, it can be indicated that the normal charging process has begun. At this time, in order to avoid overcharging during the charging process, the previously closed charging monitoring circuit can be turned on. In this way, damage to the power supply caused by the charging process can be avoided.

[0070] In some embodiments, the above-mentioned determination of whether to adjust the above-mentioned supply voltage based on the voltage difference between the first voltage value and the third preset voltage value may also specifically include: in response to determining that the voltage difference is greater than a preset threshold value, determining not to adjust the supply voltage.

[0071] As an example, when the voltage difference is greater than a preset threshold, it can indicate that the target power source has not yet been completely activated. At this time, the power supply device can continue to maintain the target voltage to activate the target power source.

[0072] In some implementations, when the voltage difference is greater than a preset threshold and the first voltage value is also less than a third preset voltage value, it can indicate that the voltage value of the target power source has dropped below the discharge termination voltage, which can indicate activation failure of the target power source.

[0073] In some embodiments, the target power source may be subjected to a first preset number of voltage detections within a third preset time period; and whether to generate prompt information may be determined based on the voltage values ​​detected the first preset number of times and a third preset voltage value.

[0074] Here, within the third preset time period, the supply voltage can continue to maintain the target voltage value.

[0075] Here, the prompt information may be used to indicate that the target power source fails to charge.

[0076] As an example, if the target power supply is activated (that is, it can be charged normally); the voltage value of the target power supply will usually not be less than the third preset voltage value (discharge termination voltage) for multiple times; therefore, it can be determined whether the target power supply can be charged normally based on the voltage values ​​of the first preset number of times detected and the third preset voltage value, and it can be determined whether to generate corresponding prompt information.

[0077] In some embodiments, whether to generate prompt information can be determined based on the voltage values ​​detected a first preset number of times and the third preset voltage value. Specifically, it can include: determining whether to generate prompt information based on the number of voltage values ​​detected a first preset number of times that are less than the third preset voltage value.

[0078] Here, if the voltage values ​​detected multiple times in the first preset number of voltage values ​​are all lower than the third preset voltage value, it can indicate that the power activation has failed at this time, and a corresponding prompt message can be generated at this time to remind the user that the target power supply has not been activated and cannot be charged.

[0079] As an example, the specific display form of the prompt information can be set according to the actual situation. For example, the specific display of the prompt information can include but is not limited to: prompt voice, flashing indicator light, etc.
