[0045] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0046] It should be noted that in the embodiments of the present application, the term "and / or" is merely a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the embodiments of the present application, the character " / " generally indicates that the associated objects are in an "or" relationship.

[0047] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and indication, configuration and configuration, etc.

[0048] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0049] While various power-off protection mechanisms exist in related technologies, most lack effective recovery logic to determine when charging can safely resume. Some solutions rely solely on simple delayed restart strategies or manual intervention, failing to make intelligent decisions based on the actual cause of the outage and device status. This leads to inappropriate recharging timing, impacting charging efficiency and safety. This not only impacts the user experience but can also waste energy or damage the device due to inappropriate recovery timing.

[0050] Figure 1 This is a flow chart of the intelligent recharging method provided in the embodiment of the present application. Figure 1 As shown, the intelligent recharging method provided in the embodiment of the present application includes the following steps S101 to S104:

[0051] Step S101: acquiring power-off data.

[0052] In the embodiment of the present application, power-off data refers to various data information collected during the charging process for determining whether a power-off operation needs to be performed, such as the current value collected from the charging circuit, such as trickle charging current, time parameters, charging temperature, power status of the powered device, etc.

[0053] In this embodiment, power outage data is not only used to determine when a power outage occurred, but also provides fundamental support for subsequent recharging logic. By recording various parameters before the power outage, it is possible to more accurately assess the most appropriate time to resume charging when calculating the recharging duration, thereby avoiding the impact of resuming charging too early or too late.

[0054] Step S102 : disconnecting the charging circuit for charging the powered device according to the power-off data to stop charging the powered device.

[0055] In the embodiment of the present application, the charging circuit refers to the power transmission path between the power supply device and the powered device. By controlling the on and off of the circuit, active intervention in the charging process can be achieved, including stopping charging and resuming charging. Determine whether to disconnect the charging circuit based on the power-off data. Once it is confirmed that the power needs to be cut off, the main power transmission channel is cut off, but the communication function of the signal line (such as the DPDM line) is maintained, thereby achieving non-sensing power off. This design makes it possible for the user not to notice the charging interruption, while being prepared for the subsequent resumption of charging.

[0056] For example, in a typical charging cycle, when the battery is close to being fully charged, a power-off operation is performed to cut off the connection between the input voltage and the battery while retaining protocol communication; for another example, in the case of a high-temperature protection power-off, when the charging temperature is detected to be too high, the charging circuit is also cut off while retaining protocol communication to prevent heat accumulation from causing damage to the powered equipment.

[0057] Step S103: determining the recharging time according to the power-off data.

[0058] In this embodiment of the present application, the recharge duration refers to the time interval for resuming charging after a power outage, calculated based on the power outage data. Setting the recharge duration helps avoid resuming charging too early or too late, thereby improving charging efficiency and user experience.

[0059] In the embodiment of the present application, a reasonable recharging time is calculated by combining the power outage data before the power outage through a preset algorithm or preset rules.

[0060] In the embodiments of the present application, the recharge time can be adjusted based on different power outage data. For example, for low-power products, the recharge time can be set to be shorter due to their faster charging speed; while for high-power, high-capacity products, the recharge time should be appropriately extended.

[0061] Step S104: connecting the charging circuit according to the recharging time to resume charging the powered device.

[0062] In this embodiment of the present application, the time of the power outage can be recorded, and charging can be resumed after the power outage reaches the set recharge duration. Alternatively, a timer can be started after the power outage, and when the timer reaches the set recharge duration, the recharge action is triggered. For example, after a power outage, the recharge duration can be set to 30 minutes. In this case, the power outage time can be recorded as 10:00, and charging can be resumed at 10:30. Alternatively, a timer can be started after the power outage, and when the timer reaches 30 minutes, the recharge action is executed.

[0063] In this embodiment of the application, reconnecting the charging circuit refers to reopening the main power transmission loop, allowing the power supply device to once again supply power to the powered device. Because only the main power path is previously disconnected, while the signal path remains unchanged, the charging process is very fast and smooth, causing almost no perceptual interference to the user.

[0064] The intelligent recharging method provided in the embodiment of the present application obtains power outage data and uses the power outage data as the basis for subsequent judgments on whether a power outage has occurred and how to calculate the recharging time. Subsequently, the method determines whether to perform a power outage based on this data, and cuts off the main power circuit through the power outage module. Next, the method calculates the appropriate recharging time based on the power outage data, and arranges the timing for resuming charging through a timer or time record. Finally, after the recharging time is reached, the main power circuit is restored and charging is restarted. The entire process forms a closed-loop control, realizing intelligent management of the charging process. By reasonably setting the recharging time, the method can make the best response in different power outage scenarios, thereby improving the overall charging efficiency, reducing energy waste, and extending the service life of the powered equipment.

[0065] refer to Figure 2 , Figure 2 The power-off process provided in this embodiment is shown in FIG. Figure 1 In the embodiment of the present application, the step 102: disconnecting the charging circuit for charging the powered device according to the power-off data; Figure 2 As shown, it includes steps 201 to 205, wherein,

[0066] Step 201: Determine a trickle charging current based on the charging data.

[0067] In the embodiments of the present application, the trickle charging current refers to the charging current dropping to a lower maintenance value when the powered device is close to being fully charged. This value is used to prevent battery overcharging and extend battery life. During this stage, the specific value of the trickle charging current is determined by the device's charging protocol, battery capacity, and current charge level. In actual application, when the charging power enters a specific range and remains within this range for a certain period of time, it can be determined that the current is in trickle mode, and the current used at this time is the trickle charging current.

[0068] In the embodiments of the present application, the trickle charge time refers to the duration that the device is in trickle charge mode, during which the charging current remains within the trickle charge current range. The time after the device enters the trickle charge phase is recorded and compared with a first preset time to determine whether the power-off condition is met. In actual implementation, the power-off operation is executed when the trickle charge time reaches the first preset time.

[0069] In the embodiments of the present application, by collecting real-time charging data, it is possible to identify whether the device has entered the trickle charging stage and accurately record the corresponding trickle charging current and trickle charging time, thereby providing a basis for subsequent power-off logic. By collecting real-time charging data and identifying whether the device has entered the trickle charging stage, it helps avoid frequent power outages or failure to shut down the power in a timely manner due to misjudgment, thereby improving the safety and stability of the charging process.

[0070] Step 202: Determine whether the trickle charging current is less than a preset current.

[0071] In the embodiment of the present application, the preset current is a pre-set threshold value used to determine whether the device has entered the trickle charging state. When the trickle charging current is detected to be lower than the preset current, it indicates that the device may be close to a full charge state and has the conditions to trigger the power-off protection.

[0072] In the embodiment of the present application, the judgment logic is designed based on the charging curve of the device. Different types of devices (such as mobile phones, tablets, laptops, etc.) have different charging characteristics, and the preset current is adjusted according to the specific device type and charging protocol. For example, when targeting low-power devices, the preset current is set to 100mA; and when targeting high-power devices, the preset current is set to 200mA or higher. It should be noted that the preset current can be set according to actual conditions, and the embodiment of the present application does not limit this.

[0073] In the embodiment of the present application, if the trickle charging current is less than the preset current, step 203 is executed; if the trickle charging current is greater than or equal to the preset current, step 201 is executed to continue to follow up the collected charging data to determine the trickle charging current.

[0074] Step 203: If the current is less than the preset current, record the trickle charging time during which the trickle charging current is less than the preset current.

[0075] When the trickle charge current is detected to be less than the preset current, the duration of this state is recorded. By accumulating sufficient data information, it can be determined whether the target device has entered a long-term stable trickle charge phase, providing the necessary data support for subsequent power-off decisions.

[0076] Step 204: Determine whether the trickle charging time is greater than or equal to a first preset time.

[0077] The first preset time is a set time threshold used to determine whether the device has been in the trickle charging state for an extended period of time. If the trickle charging duration exceeds or equals the set time threshold, it indicates that the device has been in the low-current charging phase for an extended period of time. In this case, the device can be determined to be nearing full charge and is eligible for a power-off operation.

[0078] In this embodiment of the present application, the first preset time can be set to take into account the charging characteristics of different powered devices and user usage habits. For example, for a standard smartphone, the first preset time can be set to 30 minutes; while for a high-capacity device such as a laptop, the first preset time may need to be extended to 60 minutes.

[0079] In the embodiment of the present application, if the trickle charging time is greater than or equal to the first preset time, step 205 is executed; if the trickle charging time is less than the first preset time, step 203 is executed to continue the trickle charging time in which the trickle charging current is less than the preset current.

[0080] Through the judgment logic, a power-off decision can be made at an appropriate time, avoiding the impact of premature power-off on user experience and the safety hazards caused by delayed power-off.

[0081] Step 205: If the time is greater than or equal to the first preset time, disconnect the charging circuit for charging the powered device.

[0082] When it is determined that the trickle charging time has met the first preset time, a power-off operation is executed, disconnecting the main charging circuit while keeping the signal transmission channel unobstructed to ensure normal operation of the communication function. This power-off method can be called a non-sensing power-off, that is, the power-off operation is completed without interrupting the user experience.

[0083] In the embodiments of the present application, the trickle charge current and trickle charge time are determined based on charging data, and based on the information obtained from the determination of the charging data, a determination is made as to whether to disconnect the charging circuit used to charge the powered device. By determining the trickle charge current and time based on the charging data and deciding whether to disconnect the charging circuit, it is possible to accurately identify whether the device has entered a stable charging state, thereby rationally controlling the timing of power disconnection, thereby improving charging safety and optimizing the overall charging experience.

[0084] refer to Figure 3 , Figure 3 Schematic diagram of the process for determining the recharge duration provided in the embodiment of the present application Figure 1 In the embodiment of the present application, the step 103: determining the recharging time according to the power-off data, such as Figure 2 As shown, it includes steps 206 to 208, wherein,

[0085] Step 206: Determine whether the trickle charging current is in the nth current interval.

[0086] By detecting the current trickle charge current value, it is determined whether the trickle charge current falls within one of several preset current intervals. These current intervals are set based on factors such as device type (such as high power or low power), battery capacity, and historical charging behavior. For example, for high-power devices, the trickle charge current is higher, and the corresponding lower and upper limits of the current interval are also larger; for low-power devices, the trickle charge current is lower, and the corresponding lower and upper limits of the current interval are also smaller. For example, when a computer is almost fully charged, the charging current is maintained between 120mA and 150mA, when a mobile phone is almost fully charged, the charging current is maintained between 80mA and 100mA, and when the headset is almost fully charged, the current is between 40mA and 60mA.

[0087] In the embodiment of the present application, if the trickle charging current is in the nth current interval, step 207 is executed; if the trickle charging current is not in the nth current interval, step 208 is executed.

[0088] Step 207: If it is in the nth current interval, determine the recharging time to be the time corresponding to the nth current interval.

[0089] In the embodiment of the present application, once it is confirmed that the current trickle charging current is in a specific current interval (i.e., the nth current interval), the recharging duration is determined to be the duration corresponding to the nth current interval. This mechanism allows the length of the recharging time to be dynamically adjusted according to different current levels, thereby improving the safety and efficiency of the charging process. For example, low-power devices may only require a shorter recovery time, while high-power devices may require a longer recovery time to ensure safety and stability.

[0090] In this embodiment of the present application, the nth current interval is a multiple current range divided according to the characteristics of the powered device, and each interval corresponds to a specific recharging duration. The larger the boundary value of the current interval, the higher the power consumption of the device corresponding to the nth current interval, and the longer the recharging duration corresponding to the nth current interval. This approach, based on the correspondence between current intervals and recharging durations, can intelligently adapt to different types of devices.

[0091] In an embodiment of the present application, the correspondence between the current interval and the recharging time refers to presetting multiple current intervals, each of which has a unique recharging time parameter. The mapping relationship between the current interval and the recharging time makes it possible to automatically select the appropriate recharging time based on the actual detected current interval, thereby achieving personalized processing for different types of devices. For example, one current interval may correspond to a recharging time of 5 minutes, and another current interval may correspond to a recharging time of 10 minutes. The recharging time of other current intervals is set in the same manner.

[0092] Step 208: If it is not in the nth current interval, determine the recharging time to be the preset time.

[0093] In the embodiment of the present application, if the trickle charging power does not fall within the preset current intervals, the recharging time is determined to be the preset time. The preset time can be set according to actual conditions, and the embodiment of the present application does not limit this.

[0094] In this embodiment, step 206 identifies the current current range, and steps 207 and 208 set the corresponding recharging duration based on the identification result of step 206. Throughout the entire process, each step is interdependent, forming a closed-loop control logic that ensures that reasonable judgments can be made based on real-time detection data, thereby improving the safety and efficiency of the charging process and further optimizing the user's overall charging experience.

[0095] refer to Figure 4 , Figure 4 The power-off process provided in this embodiment is shown in FIG. Figure 2 In the embodiment of the present application, the step 102: disconnecting the charging circuit for charging the powered device according to the power-off data; Figure 4 As shown, it includes steps 301 to 303, wherein,

[0096] Step 301: Determine whether the power level of the powered device is greater than a preset power level.

[0097] In the embodiments of the present application, the preset power level refers to a pre-set power threshold. When the current power level of the powered device exceeds the preset power level, the powered device is considered to be nearly fully charged or has reached a condition where charging can be stopped. The preset power level can be dynamically adjusted based on different battery types and charging strategies. For example, when managing the charge of a lithium-ion battery, the preset power level can be set to 95% to 98% to avoid the risk of overcharging and extend the service life of the battery used in the powered device.

[0098] In the embodiment of the present application, by setting a reasonable preset power level, the charging circuit used to charge the powered device can be disconnected in time when the powered device is close to a fully charged state, thereby reducing unnecessary energy loss, improving overall charging efficiency, protecting the health of the battery in the powered device, and extending the battery life of the powered device.

[0099] In the embodiment of the present application, if the power of the powered device is greater than the preset power, step 302 is executed; if the power of the powered device is less than or equal to the preset power, step 303 is executed.

[0100] Step 302: If the power level is greater than the preset power level, disconnect the charging circuit for charging the powered device.

[0101] In the embodiment of the present application, the charging circuit refers to the power transmission path between the power supply device and the powered device. In the present application, disconnecting the charging circuit means cutting off the current supply, but retaining signal communication (such as DP / DM) so that the device can be quickly identified and the charging process can be started when charging is resumed later.

[0102] For example, in a fast-charging power bank, when a user connects a mobile phone to the power bank and begins charging, the current battery level of the phone is obtained through a communication protocol. Assuming the preset battery level is 97%, when the phone's battery level reaches 97%, it is determined that the conditions for disconnecting the charging circuit have been met, and the charging circuit is disconnected while maintaining the communication link connection.

[0103] Step 303: If the power is less than or equal to the preset power, continue to collect the power of the powered device.

[0104] In the embodiment of the present application, if the power level of the powered device is less than or equal to the preset power level, the power level of the powered device continues to be collected and monitored.

[0105] In this embodiment, when the power level of the powered device exceeds a preset level, the charging circuit is disconnected, effectively preventing overcharging of the powered device. During this process, signal communication functions are maintained, ensuring seamless connection upon subsequent power restoration, enhancing the user experience.

[0106] refer to Figure 5 , Figure 5 Schematic diagram of the process for determining the recharge duration provided in the embodiment of the present application Figure 2 In the embodiment of the present application, the step 103: determining the recharging time according to the power-off data, such as Figure 5 As shown, it includes steps 304 to 310, wherein:

[0107] Step 304: Determine a trickle charging current based on the charging data.

[0108] By collecting real-time current data in the charging circuit, the current value of the device in the trickle charging stage before power failure can be obtained.

[0109] Step 305: Determine whether the trickle charging current is in the nth current interval.

[0110] Current intervals divide trickle charge currents within different ranges into several segments, each corresponding to a different handling strategy. The nth current interval represents a specific range of the currently detected trickle charge current. For example, the trickle current can be divided into three intervals: [0-10mA], [10-20mA], and [20-30mA], each representing a different charging state.

[0111] In the embodiment of the present application, if the trickle charging current is in the nth current interval, step 306 is executed; if the trickle charging current is not in the nth current interval, step 310 is executed.

[0112] Step 306: If it is the nth current interval, determine the relationship between the change value of the power of the powered device within the second preset time and the preset change amount.

[0113] The second preset time is a pre-set time window used to observe the changing trend of the device's power level. For example, if the second preset time is 5 minutes, the increase in the device's power level during these 5 minutes is counted. Within the second preset time, the difference in the device's power level is calculated, and this difference is defined as the power level change value, i.e., the power level increment. The second preset time can be set based on actual circumstances, such as 10 minutes, 30 minutes, etc., and is not limited in this embodiment of the present application.

[0114] In the embodiment of the present application, if the change value is greater than the preset change amount, step 307 is executed; if the change value is equal to the preset change amount, step 308 is executed; if the change value is less than the preset change amount, step 309 is executed.

[0115] Step 307: If the change is greater than the preset change, determining the recharging duration to be the first duration corresponding to the nth current interval;

[0116] Step 308: If the change amount is equal to the preset change amount, determining the recharging duration to be the second duration corresponding to the nth current interval;

[0117] Step 309: If the change is less than the preset change, determine the recharging duration to be a third duration corresponding to the nth current interval; wherein the first duration is less than the second duration, and the second duration is less than the third duration.

[0118] Step 310: If the trickle charging current is not in the nth current interval, determine the recharging time to be a preset time.

[0119] In the embodiment of the present application, if the trickle charging power does not fall within the preset current intervals, the recharging time is determined to be the preset time. The preset time can be set according to actual conditions, and the embodiment of the present application does not limit this.

[0120] In an embodiment of the present application, the first duration is less than the second duration, and the second duration is less than the third duration; if the change in the power of the powered device within the second preset time is greater than the preset change amount, it indicates that among the multiple devices whose trickle charging current is within the nth current interval, the battery and / or power of the powered device is relatively small, and its recharging time can be relatively short; if the change in the power of the powered device within the second preset time is less than the preset change amount, it indicates that among the multiple devices whose trickle charging current is within the nth current interval, the battery and / or power of the powered device is relatively large, and its recharging time can be relatively long.

[0121] Specifically, the system uses the trickle charge current to determine whether the device is a high-power product. It then uses the change in the device's charge level over a preset time period to further differentiate between different devices. For example, if the trickle charge current range is 120mA-150mA, the second preset time is set to 10 minutes, and the preset change is 1%. If the device's charge level increases by 1% over 10 minutes, the corresponding recovery charging time is set to 2 hours. If the device's charge level increases by less than 1% over 10 minutes, the corresponding recovery time is set to 2 hours and 20 minutes.
