[0030] In this embodiment, a method for intelligently protecting air conditioner battery charging running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] Figure 2 FIG. 1 is a flow chart of a method for intelligently protecting the battery charging of an air conditioner according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0032] Step S201, obtaining a first charging power and a second charging power, wherein the first charging power is the charging power at a first moment, the first moment is the moment when charging of the air conditioner starts, and the second charging power is the charging power at a second moment, the second moment is the moment when the charging time of the air conditioner reaches a target duration;

[0033] Specifically, the first charging power refers to the output power of the adapter at the moment of starting to charge the air conditioner battery (i.e., the first moment). This power is usually the initial power in the charging process and may be affected by the current grid voltage, adapter state, and battery initial state.

[0034] The second charging power is the output power of the adapter after the air conditioner battery is charged for a period of time (i.e., the second moment, when the time reaches the target time). The target time is a preset time interval, such as 1 minute, which is used to obtain the stable power value during the charging process to more accurately reflect the current charging state.

[0035] Step S202, calculating the difference between the first charging power and the second charging power to obtain a power difference;

[0036] Specifically, after obtaining the first charging power and the second charging power, the difference between the two power values, i.e., the power difference, is calculated. This difference reflects whether the power has changed during the charging process and the degree of change. By comparing this power difference with the preset safety threshold, it can be determined whether the charging process is normal and whether power adjustment or power-off protection is required.

[0037] Step S203, adjusting the output power of the adapter according to the power difference so as to stabilize the charging voltage, wherein the adapter is used to adjust the power used by the power supply end to charge the air conditioner.

[0038] Specifically, according to the calculated power difference, the adapter will decide whether and how to adjust its output power.

[0039] If the power difference is lower than the preset lower threshold, it means that the power is too small and the voltage is too low to meet the charging requirements. At this time, the adapter will increase the voltage appropriately through its internal voltage regulator without changing the current to increase the power to the preset normal charging power range.

[0040] If the power difference is within the preset normal range, the adapter maintains the current output power and keeps the normal charging state.

[0041] If the power difference is higher than the preset upper threshold, it means that the power is too high and the charging current is too high. The adapter will immediately cut off the power and stop charging to prevent the battery from overheating or damage. When the grid voltage drops to a safe range, the adapter will restart the charging process to ensure that the battery is charged under safe conditions.

[0042] Through this embodiment, on the basis of the portable air conditioner, when the adapter charges the portable air conditioner battery, the adapter adds a main control to detect the charging power. If the voltage fluctuates, the charging power will change. The output power of the adapter is adjusted to keep the charging voltage stable and avoid the danger caused by excessively high or low voltage, thereby improving the safety of charging for outdoor portable air conditioners.

[0043] Specifically, due to the instability of the power grid, there will be voltage fluctuations in different regions, especially in rural areas where electricity consumption is irregular and voltage fluctuations are greater. Voltage fluctuations will cause the power to be higher and the current to be higher when charging the battery. High current and long-term charging will generate high heat, causing the battery cells to burn out. Even worse, the battery may catch fire, which is extremely dangerous. There is an urgent need for an intelligent method to protect the charging of portable air-conditioning batteries, using simple methods and increasing costs as little as possible, which can not only improve comfort and user experience but also meet customer needs.

[0044] Specifically, the battery of the portable air conditioner catches fire during the charging process, which is mainly caused by unstable voltage during the charging process. When electricity is used nationwide, the voltage will fluctuate in different regions at different times. At night, when electricity consumption in cities is at its peak, the voltage in the outskirts of cities and in rural areas is low, or even fluctuating. The adapter cannot adjust to the preset voltage normally, resulting in fluctuations in the charging voltage. When the voltage is high, the power is also high, the current is also high, and the heat increases. The internal chip of the battery will burn out if it is charged for a long time under high temperature. When the voltage is low, the power is also low, resulting in a long charging time.

[0045] Specifically, by adopting the intelligent protection battery charging method of the present application, when the portable air conditioner battery is charged, the adapter intelligently determines whether the charging is normal, ensures that the battery can be charged safely during the charging process, improves the reliability of the battery, shortens the charging time, and improves the user experience.

[0046] In the specific implementation process, adjusting the output power of the adapter according to the above-mentioned power difference can be achieved through the following steps: obtaining a first difference threshold, wherein the above-mentioned first difference threshold is a preset minimum power value; obtaining a second difference threshold, wherein the above-mentioned second difference threshold is a preset maximum power value, wherein the above-mentioned first difference threshold is smaller than the above-mentioned second difference threshold; adjusting the above-mentioned output power of the above-mentioned adapter according to the size relationship between the above-mentioned power difference, the above-mentioned first difference threshold and the above-mentioned second difference threshold.

[0047] In this solution, by setting a reasonable power difference threshold, the adapter can adjust the output power according to the power difference detected in real time, ensuring that the charging power is within the preset normal range, avoiding the extension of charging time due to insufficient power, and improving charging efficiency and user experience. This method is particularly suitable for outdoor or rural areas with unstable voltage. The adapter can automatically adjust according to the current grid voltage status to achieve stable charging, enhancing the applicability and reliability of portable air conditioners in different environments.

[0048] Specifically, the first difference threshold is a preset minimum power difference value, usually marked as N0. When the detected actual power difference value is lower than this threshold value, it indicates that the charging power is insufficient and the voltage may be too low to meet the charging demand of the battery.

[0049] Specifically, the second difference threshold is a preset maximum value of the power difference, usually marked as N1. When the detected actual power difference exceeds this threshold, it means that the charging power is too high and the current may be too large, which may cause the battery to overheat or be damaged.

[0050] Specifically, after determining the first and second difference thresholds, the adapter will adjust the output power according to the relationship between the actually detected power difference P1-P0 and the two thresholds.

[0051] In some embodiments, the output power of the adapter is adjusted according to the relationship between the power difference, the first difference threshold and the second difference threshold, which can be specifically achieved through the following steps: when the power difference is less than the first difference threshold and the power difference is less than the second difference threshold, determining that the charging result is a first result, wherein the first result indicates a result of insufficient voltage; when the charging result is the first result, increasing the output power of the adapter.

[0052] In this solution, through the intelligent adjustment mechanism of the adapter, it can automatically identify and compensate for insufficient voltage, ensuring that the portable air conditioner battery can obtain sufficient charging power and avoiding the problem of too long charging time. Increasing the output power can speed up the charging speed and shorten the overall charging time, which is a significant improvement for users, especially in scenarios where fast charging is required. Even in an environment with grid voltage fluctuations, the adapter can maintain the stability of the charging process by adjusting the output power, ensuring that the battery charging is not affected by insufficient voltage. This method optimizes the charging process, reduces waiting time, and at the same time avoids charging interruptions or inefficiencies caused by insufficient voltage, thus significantly enhancing the user experience.

[0053] Specifically, since under normal circumstances, the power difference should be between the first difference threshold N0 and the second difference threshold N1, the statement "the power difference is less than the above first difference threshold" actually describes a special situation - that is, the power difference is not only lower than the first difference threshold N0, but it is also lower than the second difference threshold N1 (which logically must hold because N0 is less than N1). This indicates that the charging power is lower than the expected normal value, that is, the so-called "insufficient voltage" state.

[0054] Specifically, when the adapter detects that the charging result is the first result, that is, insufficient voltage, it will automatically adjust its output power, increasing the voltage to boost the power and ensuring that the charging power can reach or be maintained within the preset normal charging power range. This adjustment is made while keeping the current constant to prevent battery overload.

[0055] Suppose in the charging system of the portable air conditioner battery, the first difference threshold N0 is set to 260W and the second difference threshold N1 is set to 300W. These values are set based on the rated charging power of the battery and safety considerations.

[0056] The user connects the adapter to the portable air conditioner battery and the power supply and starts charging. The adapter begins to detect the power P0 at the start of charging and the stable power P1 after 1 minute to calculate the power difference ΔP = P1 - P0.

[0057] In an actual charging scenario, suppose P0 = 0W. After 1 minute, the power P1 detected by the adapter is 120W. At this time, the calculated power difference ΔP = 120W.

[0058] Since ΔP = 120W, obviously ΔP < N0 = 260W and is also less than N1 = 300W. Therefore, according to the above description, the adapter determines the charging result as the first result, that is, insufficient voltage.

[0059] After determining that the charging result is the first result of insufficient voltage, the adapter automatically adjusts the output power through its internal voltage regulator. Assuming that under the current conditions, the adapter can safely increase the output voltage to a higher level to increase the power to 260W while ensuring that the charging current remains within a safe range.

[0060] The adapter increases the output power from 120W to 260W, which enables the charging process to meet the charging needs of the battery and avoids the problem of long charging time.

[0061] In the specific implementation process, according to the relationship between the power difference, the first difference threshold and the second difference threshold, the output power of the adapter is adjusted, which can be achieved by the following steps: when the power difference is greater than or equal to the first difference threshold and the power difference is less than or equal to the second difference threshold, the charging result is determined to be the second result, wherein the second result indicates a normal voltage result; when the charging result is the second result, the adapter is controlled to maintain the current output power and continue to operate.

[0062] In this solution, when the power difference falls within the normal range, the charging process is stable, avoiding safety issues that may be caused by excessively high or low power, such as battery overheating, damage, or long charging time. Maintaining the output of the adapter within the normal charging power range can avoid unnecessary power adjustments, ensure efficient charging, shorten charging time, and improve user experience.

[0063] Specifically, if the power difference ΔP falls between the first difference threshold N0 and the second difference threshold N1, that is, N0≤ΔP≤N1, the adapter will determine that the current charging state is a result of normal voltage, which is the so-called second result. This means that the current charging power is neither too low (resulting in a longer charging time) nor too high (which may cause battery overheating or damage), and is within an ideal charging power range.

[0064] Once the adapter determines that the charging result is the second result, that is, the voltage is normal, it will maintain the current output power unchanged and continue the charging process, ensuring that the charging is both safe and efficient until the battery is fully charged.

[0065] Assume that the preset parameters of the portable air conditioner battery charging system are: the first difference threshold value N0 = 260 W, the second difference threshold value N1 = 300 W. This means that the adapter will consider that the change of charging power between 260 W and 300 W is acceptable and the charging state is normal.

[0066] Use the adapter to charge the portable air conditioner battery under the conditions of a stable temperature of 25-30℃ and 60% humidity.

[0067] When charging starts, the adapter detects an initial charging power P0 of 0 W. One minute later, the adapter detects again, and the charging power P1 is now 300 W. The power difference ΔP is calculated to be P1-P0=300 W.

[0068] Since ΔP=300 W, which is exactly equal to the second difference threshold N1, the adapter determines the charging result as the second result, ie, the result that the voltage is normal.

[0069] Based on the above judgment, the adapter maintains the current output power of 300W and continues charging until the battery is fully charged. During this process, the adapter will continue to monitor the power difference to ensure that it is always within the preset normal range.

[0070] In some embodiments, the output power of the adapter is adjusted according to the relationship between the power difference, the first difference threshold and the second difference threshold, which can be specifically achieved through the following steps: when the power difference is greater than the first difference threshold and the power difference is greater than the second difference threshold, determining that the charging result is a third result, wherein the third result indicates a result of voltage overload; when the charging result is the third result, reducing the output power of the adapter.

[0071] In this solution, by setting the second difference threshold, when the power difference exceeds the second difference threshold, the adapter can immediately reduce the output power to avoid battery overheating caused by high-power charging, thereby protecting the battery cells, extending the battery life, and preventing safety issues such as battery fire. This can effectively deal with the situation of abnormal increase in grid voltage and avoid potential safety hazards caused by high-voltage and high-power charging, such as burning of the chip inside the battery or damage to the adapter.

[0072] Specifically, when the power difference ΔP detected by the adapter is greater than the first difference threshold N0 and also greater than the second difference threshold N1, that is, ΔP>N1, this indicates that the current charging power is much higher than the upper limit of the normal charging power, and the charging result is determined as the third result, that is, the voltage overload result. This means that the grid voltage is abnormally high, resulting in excessive charging power, which may cause damage to the battery or safety hazards.

[0073] After determining that the charging result is the third result of voltage overload, the adapter will automatically reduce its output power. The purpose of this adjustment is to reduce the charging power to a safe range, avoid overheating, overcharging or damage to the battery due to excessive charging power, and ensure the safety of the charging process and the reliability of the battery.

[0074] Assume that in the charging system of the portable air conditioner battery, the first difference threshold value N0 is set to 260W, and the second difference threshold value N1 is set to 300W. These values ​​are set based on the safe charging power range of the battery and the prevention of overheating.

[0075] The user connects the adapter to the portable air conditioner battery and power supply to start charging. The adapter starts to detect the power P0 at the beginning of charging and the stable power P1 after 1 minute to calculate the power difference ΔP = P1-P0.

[0076] In an actual charging scenario, assuming P0 = 0 W, after 1 minute, the power detected by the adapter is P1 = 450 W. At this time, the calculated power difference ΔP = 450 W, and it is obvious that ΔP>N0 = 260 W, and it is also greater than N1 = 300 W. Therefore, according to the above description, the adapter determines the charging result as the third result, that is, voltage overload.

[0077] After determining that the charging result is the third result of voltage overload, the adapter automatically reduces the output power through its internal voltage and current regulation mechanism. Assuming that under the current conditions, the adapter is able to reduce the output power from 450W to 280W to ensure that the charging power remains within a safe range while avoiding the risk of battery overheating. After reducing the output power, the adapter will continue to monitor the power changes to ensure a stable charging process.

[0078] The adapter will maintain real-time detection of power. If it subsequently detects that the power difference exceeds the preset threshold again, it will repeat the above adjustment process to keep the output power within a safe range until the battery is fully charged.

[0079] Specifically, the schematic diagram of charging the portable air conditioner battery through the adapter is as follows Figure 3 As shown, the portable air conditioner adapter 10 is used to convert voltage, converting 220V into 24V to charge the portable air conditioner 20 battery. One end of the three-phase plug is used to connect to the 220V mains power, and the other end of the aviation plug is used to connect to the portable air conditioner battery for charging. The middle part is a voltage converter, which converts the 220V voltage into 24V. The portable air conditioner battery can power the portable air conditioner when there is no power supply outdoors, and can also be charged through the adapter.

[0080] Specifically, the control logic of the portable air conditioner battery charging adapter is as follows: Figure 4As shown in the figure, when the customer uses the smart adapter to charge the portable air conditioner battery, the adapter is connected to the portable air conditioner battery, the power is turned on and charged for 1 minute. The adapter detects the charging power P. When it detects that P1-P0<N0, the stable power after 1 minute is different from the power when it is turned on. After 1 minute, the power is more stable and closer to the real power. The power is lower than 260W. The power detection is too low and the voltage is too low, which cannot meet the charging requirements and will affect the charging time. The long charging time leads to a poor user experience. Through the voltage regulator inside the adapter, the voltage is adjusted while the current remains unchanged. The power is increased to within 260W to 300W to meet the charging requirements. When N0≤P1-P0<N1 is detected, the power is between 260W and 300W after 1 minute, which just meets the battery charging power. The general charging time is 3-4h. When N1<P1-P0 is detected, the power is greater than 300W after 1 minute. The power is too high. On the one hand, the current is too large and the heat is serious. The temperature of the capacitor inside the battery and the adapter increases, which affects the life of the adapter and burns the adapter. The adapter is directly powered off and restarts charging after the voltage drops and stabilizes. The power angle code 1 and 0 represent the adapter charging power of 1 minute minus the adapter charging power of 0 minute.

[0081] Specifically, the meanings of the above letters are shown in Table 1.

[0082] Table 1

[0083]

[0084]

[0085] The test data shows that when the adapter is used to charge the portable air conditioner at an ambient temperature of 25-30℃ and a humidity of 60%, the three adapters meet the charging time of 3.5-3.63h at normal charging power, and the three adapters meet the charging time of more than 5h at low charging power.

[0086] Specifically, the operating parameters of multiple adapters are shown in Table 2.

[0089] In the specific implementation process, the output power of the above-mentioned adapter is adjusted according to the size relationship between the above-mentioned power difference, the above-mentioned first difference threshold and the above-mentioned second difference threshold, which can be achieved through the following steps: when the charging result is the above-mentioned third result, the above-mentioned adapter is controlled to stop charging the above-mentioned air conditioner; the voltage value of the power supply end is obtained, and when the above-mentioned voltage value is within the normal range, the above-mentioned adapter is controlled to continue charging the above-mentioned air conditioner.

[0090] In this solution, by immediately stopping charging in response to abnormal charging results, safety hazards such as battery overheating, damage, and even fire can be effectively avoided, ensuring the safety of the charging process. The adapter can independently determine the power supply voltage status and intelligently control the start and stop of charging without user intervention, which improves the intelligence level of the charging system. The timely stop and restart charging mechanism can reduce the working time of the battery and adapter under abnormal voltage conditions, thereby extending the service life of the equipment and reducing maintenance costs.

[0091] Specifically, when the adapter detects that the charging result is the third result, that is, the current charging state poses a potential safety risk to the battery or adapter, such as overheating caused by excessive charging power, the adapter will be immediately controlled to stop charging the portable air conditioner battery to prevent further damage.

[0092] After the adapter stops charging, it continues to monitor the voltage at the power supply to determine whether the voltage has returned to normal. This is usually achieved through a voltage detection circuit inside the adapter, which can still detect the input voltage even if charging has stopped.

[0093] Once it is detected that the voltage value at the power supply end is again within the normal range, that is, within the preset voltage threshold range, the adapter will restart and continue to charge the portable air conditioner battery to complete the charging process.

[0094] The adapter can be designed with an independent voltage detection circuit. When the main circuit of the adapter is powered off, this circuit can still obtain enough power from the backup battery, super capacitor or external power supply (if the adapter is designed with a backup power access point) to detect whether the input voltage has returned to the normal range. This design ensures that the voltage detection function can still operate even when the main circuit is powered off.

[0095] When the power is off, the main controller of the adapter can set a delay time. During this time, although the adapter stops supplying power to the battery, it does not completely cut off the connection with the grid. Instead, it keeps the voltage detection circuit powered and continuously monitors the changes in the grid voltage. Once it detects that the voltage returns to normal, the main controller will restart the adapter and resume the charging process.

[0096] After the power is cut off, the adapter can be designed to automatically try to reconnect to the grid at a preset interval (for example, every 5 minutes). At this time, the adapter will briefly start its voltage detection circuit to check whether the grid voltage has returned to normal. If the voltage is normal, the adapter will restart charging; if the voltage is still abnormal, the adapter will continue to remain in the power-off state until the voltage returns to normal.

[0097] In some embodiments, after obtaining the first charging power and the second charging power, the method further includes the following steps: obtaining a charging duration, wherein the charging duration is the duration from the first moment to the current moment; determining a charging timeout when the charging duration is greater than or equal to a preset duration threshold; and generating a warning message when a charging timeout is determined.

[0098] In this solution, by setting a preset time threshold T and monitoring the charging time in real time, it is possible to detect abnormally extended charging time in time, prevent the battery from overheating or damage due to long-term charging, and ensure the safety of the charging process. Timely warning information allows users to understand possible charging problems and respond quickly when charging is abnormal, avoiding long waits without knowing whether the battery can be fully charged, thereby improving users' trust in the product and satisfaction with the charging process. The generation of warning information helps prevent potential charging failures, such as adapter or battery failure, and provides maintenance personnel with a basis for diagnosing charging abnormalities, facilitating subsequent troubleshooting and repairs.

[0099] Specifically, the adapter or charging management system records the time from the first moment of charging to the current moment, and calculates the difference between these two time points, which is the charging time. This process can be achieved through a built-in clock module and software algorithm.

[0100] Specifically, in order to ensure that the portable air conditioner battery is charged within a reasonable time, a preset charging time threshold T is set. If the detected charging time reaches or exceeds the preset T, it will be determined as charging timeout.

[0101] Specifically, once charging timeout is determined, an early warning message will be generated to alert users or maintenance personnel to charging anomalies. The early warning message can be in the form of an audible alarm, a screen display warning message, a mobile phone APP notification, etc., so that users can take appropriate measures, such as checking the charging environment, disconnecting the power supply, or consulting technical support.

[0102] Assuming that the normal charging time of a portable air conditioner battery is 3.5 hours, the preset time threshold T is set to 3.5 hours. This threshold is determined after considering the battery capacity, charging efficiency and safety factors, aiming to ensure that the battery is fully charged within a reasonable time while avoiding overheating caused by long-term charging.

[0103] Before camping outdoors, the user connects the portable air conditioner battery to the smart adapter to start charging. The built-in clock module of the adapter records the first moment of charging.

[0104] The adapter continuously monitors the charging time from the first moment to the current moment. For example, when charging is performed for 1 hour, the adapter records and compares whether this time exceeds the preset time threshold T. Obviously, in the case of 1 hour, the charging time is far from 3.5 hours, so the monitoring continues.

[0105] Considering the fluctuation of grid voltage and the impact of charging environment, it is assumed that during a charging process, due to voltage instability, the adapter adjusts the output power multiple times, resulting in a gradual increase in charging time. When the adapter detects that charging has lasted for 4 hours, that is, the charging time L = 4 hours, and finds that L ≥ T = 3.5 hours, it will determine that the charging has timed out.

[0106] When the charging timeout is determined, the adapter immediately generates a warning message in the form of:

[0107] Sound an alarm to alert the user.

[0108] "Charging timed out, please check the environment or contact technical support" is displayed on the adapter's display.

[0109] Through wireless connection, the warning information is sent to the user's mobile phone APP to inform the user of charging abnormalities.

[0110] After receiving the warning information, users can take the following actions:

[0111] Check the charging environment, such as whether there are any obstructions that affect heat dissipation, whether the power supply is stable, etc.

[0112] If conditions permit, disconnect the adapter and allow the battery to cool for a while before attempting to charge again.

[0113] If the charging environment is normal, you may need to contact technical support to check whether there is a fault with the adapter or battery.

[0114] Specifically, the results of charging tests on portable air conditioner batteries are shown under specific environmental conditions, that is, the ambient temperature is 25-30℃ and the humidity is 60%. Specifically, it involves the effect of charging power on charging time when using an adapter to charge a portable air conditioner battery. For "three sets of adapters meet the charging time of 3.5-3.63h at normal charging power", this means that under normal charging power conditions (that is, the power is within the range where the adapter can effectively and safely charge the battery), three different sets of adapters can fully charge the portable air conditioner battery within 3.5 to 3.63 hours. This shows that the charging process is both fast and effective, meeting the charging needs of portable air conditioner batteries. For "three sets of adapters do not meet the charging time when the charging power is low and all three sets are higher than 5h", this means that when the charging power of the adapter is lower than the normal range, the time required for the three different sets of adapters to charge the portable air conditioner battery exceeds 5 hours. This shows that the lack of charging power leads to an extension of the charging time, which cannot meet the charging efficiency standards of portable air conditioner batteries, thereby affecting the user experience.

[0115] In summary, the scheme of this application is based on the portable air conditioner. When the adapter charges the portable air conditioner battery, the adapter adds a main control to detect the charging power. When the detected power is compared with the preset value, if it is higher than the preset value, the adapter controls the power off to ensure that the battery can be charged safely during the charging process, and improve the reliability of the battery. When it is lower than the preset value, the adapter control logic cannot be used to adjust the voltage to meet the charging, shorten the charging time, and improve the user experience. This solves the problem of high temperature on the surface of the portable air conditioner battery and burnout of the battery cell when charging; it also solves the problem of long charging time when charging the portable air conditioner battery.

[0116] The embodiment of the present application also provides a device for intelligently protecting the battery charging of an air conditioner. It should be noted that the device for intelligently protecting the battery charging of an air conditioner in the embodiment of the present application can be used to execute the method for intelligently protecting the battery charging of an air conditioner provided in the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and those that have been described will not be repeated here. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0117] The following is an introduction to the device for intelligently protecting the charging of the air conditioner battery provided in the embodiment of the present application.

[0118] Figure 5 1 is a structural block diagram of a device for intelligently protecting the battery charging of an air conditioner according to an embodiment of the present application. Figure 5 As shown, the device comprises:

[0119] The first acquisition unit 100 is used to acquire a first charging power and a second charging power, wherein the first charging power is the charging power at a first moment, the first moment is the moment when charging of the air conditioner starts, and the second charging power is the charging power at a second moment, the second moment is the moment when the charging time of the air conditioner reaches a target duration;

[0120] The calculation unit 200 is used to calculate the difference between the first charging power and the second charging power to obtain a power difference;

[0121] The adjustment unit 300 is used to adjust the output power of the adapter according to the power difference so as to stabilize the charging voltage, wherein the adapter is used to adjust the power of the power supply end for charging the air conditioner.

[0122] Through this embodiment, on the basis of the portable air conditioner, when the adapter charges the portable air conditioner battery, the adapter adds a main control to detect the charging power. If the voltage fluctuates, the charging power will change. The output power of the adapter is adjusted to keep the charging voltage stable and avoid the danger caused by excessively high or low voltage, thereby improving the safety of charging for outdoor portable air conditioners.

[0123] In the specific implementation process, the adjustment unit includes a first acquisition module, a second acquisition module and an adjustment module, the first acquisition module is used to obtain a first difference threshold, wherein the first difference threshold is a preset minimum power value; the second acquisition module is used to obtain a second difference threshold, wherein the second difference threshold is a preset maximum power value, wherein the first difference threshold is less than the second difference threshold; the adjustment module is used to adjust the output power of the adapter according to the relationship between the power difference, the first difference threshold and the second difference threshold.

[0124] In this solution, by setting a reasonable power difference threshold, the adapter can adjust the output power according to the power difference detected in real time, ensuring that the charging power is within the preset normal range, avoiding the extension of charging time due to insufficient power, and improving charging efficiency and user experience. This method is particularly suitable for outdoor or rural areas with unstable voltage. The adapter can automatically adjust according to the current grid voltage status to achieve stable charging, enhancing the applicability and reliability of portable air conditioners in different environments.

[0125] In some embodiments, the adjustment module includes a first determination submodule and a first adjustment submodule, the first determination submodule is used to determine that the charging result is a first result when the power difference is less than the first difference threshold and the power difference is less than the second difference threshold, wherein the first result indicates a result of insufficient voltage; the first adjustment submodule is used to increase the output power of the adapter when the charging result is the first result.

[0126] In this solution, the adapter's intelligent adjustment mechanism can automatically identify and compensate for insufficient voltage, ensuring that the portable air conditioner battery can obtain sufficient charging power and avoiding the problem of long charging time. Increasing the output power can speed up charging and shorten the overall charging time, which is a significant improvement for users, especially in scenarios that require fast charging. Even in an environment where the grid voltage fluctuates, the adapter can maintain the stability of the charging process by adjusting the output power to ensure that the battery charging is not affected by insufficient voltage. This method significantly improves the user experience by optimizing the charging process, reducing waiting time, and avoiding charging interruptions or inefficiencies due to insufficient voltage.

[0127] During the specific implementation process, the adjustment module includes a second determination submodule and a second adjustment submodule. The second determination submodule is used to determine that the charging result is a second result when the above-mentioned power difference is greater than or equal to the above-mentioned first difference threshold and the above-mentioned power difference is less than or equal to the above-mentioned second difference threshold, wherein the above-mentioned second result indicates a normal voltage result; the second adjustment submodule is used to control the above-mentioned adapter to maintain the current above-mentioned output power and continue to operate when the charging result is the above-mentioned second result.

[0128] In this solution, when the power difference falls within the normal range, the charging process is stable, avoiding safety issues that may be caused by excessively high or low power, such as battery overheating, damage, or long charging time. Maintaining the output of the adapter within the normal charging power range can avoid unnecessary power adjustments, ensure efficient charging, shorten charging time, and improve user experience.

[0129] In some embodiments, the adjustment module includes a third determination submodule and a third adjustment submodule, the third determination submodule is used to determine that the charging result is a third result when the power difference is greater than the first difference threshold and the power difference is greater than the second difference threshold, wherein the third result indicates a result of voltage overload; the third adjustment submodule is used to reduce the output power of the adapter when the charging result is the third result.

[0130] In this solution, by setting the second difference threshold, when the power difference exceeds the second difference threshold, the adapter can immediately reduce the output power to avoid battery overheating caused by high-power charging, thereby protecting the battery cells, extending the battery life, and preventing safety issues such as battery fire. This can effectively deal with the situation of abnormal increase in grid voltage and avoid potential safety hazards caused by high-voltage and high-power charging, such as burning of the chip inside the battery or damage to the adapter.

[0131] During the specific implementation process, the adjustment module includes a fourth adjustment sub-module and a fifth adjustment sub-module. The fourth adjustment sub-module is used to control the adapter to stop charging the air conditioner when the charging result is the third result; the fifth adjustment sub-module is used to obtain the voltage value of the power supply end, and when the voltage value is within a normal range, control the adapter to continue charging the air conditioner.

[0132] In this solution, by immediately stopping charging in response to abnormal charging results, safety hazards such as battery overheating, damage, and even fire can be effectively avoided, ensuring the safety of the charging process. The adapter can independently determine the power supply voltage status and intelligently control the start and stop of charging without user intervention, which improves the intelligence level of the charging system. The timely stop and restart charging mechanism can reduce the working time of the battery and adapter under abnormal voltage conditions, thereby extending the service life of the equipment and reducing maintenance costs.

[0133] In some embodiments, the above-mentioned device also includes a second acquisition unit, a determination unit and a generation unit, the second acquisition unit is used to obtain the charging duration after acquiring the first charging power and the second charging power, wherein the above-mentioned charging duration is the duration of charging from the above-mentioned first moment to the current moment; the determination unit is used to determine that the charging timeout is in the case that the above-mentioned charging time is greater than or equal to a preset duration threshold; the generation unit is used to generate a warning message when it is determined that the charging timeout has occurred.

[0134] In this solution, by setting a preset time threshold T and monitoring the charging time in real time, it is possible to detect abnormally extended charging time in time, prevent the battery from overheating or damage due to long-term charging, and ensure the safety of the charging process. Timely warning information allows users to understand possible charging problems and respond quickly when charging is abnormal, avoiding long waits without knowing whether the battery can be fully charged, thereby improving users' trust in the product and satisfaction with the charging process. The generation of warning information helps prevent potential charging failures, such as adapter or battery failure, and provides maintenance personnel with a basis for diagnosing charging abnormalities, facilitating subsequent troubleshooting and repairs.
