[0049] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application is described in detail below in conjunction with the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other implementation methods obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0050] It should be noted that when charging the batteries on household appliances, an adapter is connected between the power source and the battery. The existing adapter is a power supply conversion device for small portable electronic devices and electronic appliances. It is generally composed of a casing, a power transformer and a rectifier circuit. According to its output type, it can be divided into AC output type and DC output type.

[0051] When charging outdoors, the outdoor environment is relatively unstable and is greatly affected by the charging environment. For example, when the temperature is low, the battery will take too long to charge. For example, the test data is given below. The adapter is used to charge a portable air conditioner with two different batteries at an ambient temperature of 0-80℃ and a humidity of 60%. The two sets of batteries meet the charging time of 3.4-3.7h at normal charging temperature, and the two sets of batteries meet the charging time of more than 7h at low charging temperature. See Table 1 for details:

[0052]

[0053]

[0054] When the temperature is too high, the battery will overheat, causing the battery cells to burn out or even catch fire.

[0055] Take portable air conditioners as an example: the users of portable air conditioners are all different, with different living environments and usage habits. It cannot be guaranteed that the charging environment of the portable air conditioner battery can be met. Corrosion and high temperature environments are inevitable. When charging in a corrosive environment, the electrical equipment in the battery will be corroded, reducing the charging time. When charging at high temperature, the battery may catch fire and cause safety problems. This is mainly because the ambient temperature is high during the high-temperature charging process, and the temperature also rises during the charging process. The internal chip of the battery will burn out if it is charged for a long time under high temperature.

[0056] The schematic diagram of the portable air conditioner battery in this application being charged through an adapter is as follows Figure 1 The portable air conditioner adapter 1 is used to convert voltage, converting 220V into 24V to charge the portable air conditioner battery 2. The three-phase plug at one end is used to connect to the 220V mains power, and the aviation plug at the other end is used to connect to the portable air conditioner battery for charging. The voltage converter in the middle part converts the 220V voltage into 24V, so that the portable air conditioner battery 2 can power the portable air conditioner when there is no power supply outdoors, and can also be charged through the adapter 1.

[0057] Therefore, to solve this problem, refer to Figure 2 , an embodiment of the present application provides a battery charging control method, applied to an adapter, comprising:

[0058] S11: Acquire target parameters, where the target parameters include battery temperature, air humidity, and air pH;

[0059] First of all, it should be noted that the battery is equipped with sensors, such as a temperature sensor, a humidity sensor, and a pH sensor. When the battery is connected to a power source through an adapter, the chip in the adapter obtains the sensor parameters.

[0060] In another implementation, a sensor is provided on the adapter, and sensor parameters are obtained when the adapter is connected to a battery or a power source.

[0061] That is, as the preferred implementation method of the present application, when obtaining target parameters such as battery temperature, air humidity and air pH, it is necessary to start charging the battery, because the adapter generally does not have a separate power supply. Only when it is connected to the power supply and the battery respectively, the adapter will be powered and the internal chip will be powered on and work.

[0062] Of course, in practice, a power storage device can also be separately configured in the adapter, so that when the power storage device has power, it does not need to be connected to a power source to measure target parameters such as battery temperature, air humidity, and air pH. When connected to a power source, the energy storage device can be charged.

[0063] It should be noted that the reason why the target parameters of this application include air pH and air humidity is that when charging a conventional indoor battery, it is not necessary to consider air pH and air humidity, because the indoor environment is relatively stable and there is no unstable environment. However, the outdoor environment is changeable, so air pH and air humidity need to be considered.

[0064] S12: Determine a battery charging control strategy based on the target parameter;

[0065] In one embodiment, a battery charging control strategy is determined based on real-time target parameters.

[0066] Exemplary:

[0067] When the battery temperature is less than the first temperature threshold, the charging control strategy of the battery is determined to be to continue charging and increase the charging current. When the battery temperature is greater than the second temperature threshold, the charging control strategy of the battery is determined to be to suspend charging. Wherein, the first temperature threshold is less than or equal to the second temperature threshold. When the first temperature threshold and the second temperature threshold are not equal, when the battery temperature is greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold, the charging control strategy of the battery is determined to be to continue charging. Because when the battery temperature is too low (i.e., less than the first temperature threshold), the battery charging time is long and the charging efficiency is low, but it will not cause damage to the battery, so it is kept to continue charging, and at the same time, the battery is heated by increasing the charging current to increase the battery temperature. When the battery temperature is too high (i.e., greater than the second temperature threshold), it will cause the battery to overheat, and there is a hidden danger of damaging the battery or even causing safety problems. Therefore, it is necessary to suspend charging at this time, and remind the user to change the charging environment or seal the charging. When the temperature is suitable (i.e., greater than or equal to the first temperature threshold and less than or equal to the second temperature threshold), there is no such problem, charging can continue, and there is no need to increase the charging current.

[0068] When the air humidity is less than the humidity threshold, the charging control strategy of the battery is determined to continue charging. When the air humidity is greater than or equal to the humidity threshold, the charging control strategy of the battery is determined to suspend charging. Because when the air humidity is low (i.e., less than the humidity threshold), the risk of battery corrosion is small, so charging is continued, and when the air humidity is high (i.e., greater than or equal to the humidity threshold), the risk of battery corrosion is high, so charging is suspended.

[0069] When the air pH is less than the first pH threshold, the charging control strategy of the battery is determined to be suspended charging. When the air pH is greater than the second pH threshold, the charging control strategy of the battery is determined to be suspended charging. Among them, the first pH threshold is less than the second pH threshold. When the air pH is greater than or equal to the first pH threshold and less than or equal to the second pH threshold, the charging control strategy of the battery is determined to continue charging. Because when the air pH is too low (i.e., less than the first pH threshold), it will cause damage to the battery, so charging is suspended. When the air pH is too high (i.e., greater than the second pH threshold), there is a problem of damaging the battery, so it is necessary to suspend charging at this time, and remind the user to change the charging environment or do a good job of sealing the charging. When the pH is appropriate (i.e., greater than or equal to the first pH threshold and less than or equal to the second pH threshold), there is no above-mentioned problem, and charging can continue.

[0070] However, during the actual test process, the inventor of the present application found that the charging control strategy determined by the real-time target parameters may not be consistent with the actual situation. For example, although the air humidity and air pH are not suitable for continued charging, the user has done special treatment on the battery, such as sealing, so the air humidity and air pH have little effect on the battery charging, so there is no need to suspend charging. The problem with other charging control strategies determined by real-time target parameters is that different batteries have different thresholds. For example, different batteries have different battery temperature ranges suitable for charging, and different batteries need to be configured with different thresholds. This increases the production cost of the adapter.

[0071] Based on this, the present application provides another preferred implementation method, which determines the charging control strategy based on the target parameter difference at the beginning of charging and after a period of time, that is, the charging environment is determined by the change in the target parameter after the battery is charged. In this way, when the user performs special treatment on the battery, the change in the target parameter during charging will be within an appropriate range, and the temperature change during battery charging is standard, so there is no need to set different standards, which will not increase the production cost of the adapter. The details are as follows:

[0072] The first target parameter when the charging starts for the first preset time is obtained, and the second target parameter when the charging starts for the second preset time is obtained; wherein the first preset time is less than the second preset time, and it can be understood that the first target parameter and the second target parameter are generally parameters shortly after the charging starts, because if the time is longer, the battery may be seriously damaged. The specific values ​​of the first preset time and the second preset time are set according to actual needs.

[0073] Calculating a target parameter difference between the second target parameter and the same target parameter in the first target parameter, wherein the target parameter difference includes a temperature difference, a humidity difference, and a pH difference;

[0074] A charging control strategy for the battery is determined based on the target parameter difference.

[0075] In one embodiment, determining the charging control strategy of the battery based on the target parameter difference includes:

[0076] When all target parameter differences are within a preset range, the charging control strategy of the battery is determined to continue charging.

[0077] When any target parameter difference is not within the preset range, the charging control strategy of the battery is determined to be charging suspension.

[0078] That is, the control method of this embodiment only sets different preset ranges for different target parameters, and then determines whether the target parameter difference is within the corresponding preset range. If it is, the charging control strategy of the battery is determined to continue charging; if not, the charging control strategy of the battery is determined to suspend charging. The control logic is simple.

[0079] However, in practice, when the target parameter is the battery temperature, if the battery temperature is not within the preset range and is relatively low, the battery can continue to be charged, but the charging efficiency is relatively low and the charging time is relatively long. Therefore, in another embodiment, the charging control strategy of the battery is determined based on the target parameter difference, including:

[0080] When all target parameter differences are within a preset range, the charging control strategy of the battery is determined to continue charging.

[0081] When any target parameter difference value is not within the preset range, a charging control strategy for the battery is determined based on a bad target parameter difference value, wherein the bad target parameter difference value is a target parameter difference value not within the preset range.

[0082] That is, in this embodiment, when all target parameter differences are within a preset range, the charging control strategy of the battery is determined to continue charging; otherwise, the charging control strategy of the battery is determined based on the poor target parameter differences.

[0083] As a preferred implementation of the embodiment of the present application, determining the charging control strategy of the battery based on the bad target parameter difference includes:

[0084] If the bad target parameter difference includes a temperature difference, the charging control strategy of the battery is determined based on the magnitude relationship between the temperature difference and the preset range.

[0085] If the bad target parameter difference does not include a temperature difference, it is determined that the charging control strategy of the battery is to suspend charging.

[0086] Further, determining the charging control strategy of the battery based on the magnitude relationship between the temperature difference and the preset range includes:

[0087] When the temperature difference is less than a first preset temperature difference, the charging control strategy of the battery is determined to continue charging and increase the charging current, wherein the first preset temperature difference is a lower limit of a preset range corresponding to the temperature difference.

[0088] When the temperature difference is greater than a second preset temperature difference, the charging control strategy of the battery is determined to be charging suspension, wherein the second preset temperature difference is an upper limit value of a preset range corresponding to the temperature difference.

[0089] S13: Controlling the charging process of the battery based on the charging control strategy.

[0090] Wherein, controlling the charging process of the battery based on the charging control strategy includes:

[0091] When it is determined that the charging control strategy of the battery is to suspend charging, a reminder is sent to the user in a first preset form, wherein the first preset form includes at least one of the following:

[0092] Sounds, words, lights, patterns and codes.

[0093] When it is determined that the charging control strategy of the battery includes maintaining continuous charging, a reminder is sent to the user in a second preset form, wherein the second preset form includes at least one of the following:

[0094] Sounds, words, lights, patterns and codes.

[0095] For example, a general adapter is provided with an LED light, which displays a red light during normal charging and a green light when fully charged. The present application reminds the user to continue charging by having a constantly lit red light and reminds the user to pause charging by having a flashing red light.

[0096] In addition, as an optional implementation scheme of an embodiment of the present application, when it is determined that the charging control strategy of the battery is to continue charging and increase the charging current, the increase amount or increase coefficient of the charging current is determined based on the difference between the first preset temperature difference and the temperature difference, wherein the greater the difference between the first preset temperature difference and the temperature difference, the greater the increase amount or increase coefficient, and the smaller the difference between the first preset temperature difference and the temperature difference, the smaller the increase amount or increase coefficient, wherein the increase coefficient is greater than 1. In addition, the increase in charging current mentioned in this application refers to increasing the charging current (i.e., increasing the charging power) while the charging voltage remains unchanged.

[0097] The battery charging control method provided in the embodiment of the present application determines the battery charging control strategy according to the target parameters after obtaining the target parameters in the environment, and controls the battery charging process based on the charging control strategy. Since the charging control strategy is determined according to the target parameters of the environment, when the battery is charged outdoors, even if the environment is not conducive to charging, the battery charging process can be controlled in real time to ensure that the battery will not be corroded and the charging time will be reduced, and that the battery will not be overheated during the charging period, so that the battery cells will not burn out, and the battery charging safety is ensured.

[0098] Based on the same inventive concept, Figure 3 As shown, the present application also provides a battery charging control device 30, which is applied to an adapter, including:

[0099] A target parameter acquisition module 31 is used to acquire target parameters, wherein the target parameters include battery temperature, air humidity and air pH;

[0100] First of all, it should be noted that the battery is equipped with sensors, such as a temperature sensor, a humidity sensor, and a pH sensor. When the battery is connected to a power source through an adapter, the chip in the adapter obtains the sensor parameters.

[0101] In another implementation, a sensor is provided on the adapter, and sensor parameters are obtained when the adapter is connected to a battery or a power source.

[0102] That is, as the preferred implementation method of the present application, when obtaining target parameters such as battery temperature, air humidity and air pH, it is necessary to start charging the battery, because the adapter generally does not have a separate power supply. Only when it is connected to the power supply and the battery respectively, the adapter will be powered and the internal chip will be powered on and work.

[0103] Of course, in practice, a power storage device can also be separately configured in the adapter, so that when the power storage device has power, it does not need to be connected to a power source to measure target parameters such as battery temperature, air humidity, and air pH.

However, the outdoor environment is changeable, so air pH and air humidity need to be considered.

[0108] When the battery temperature is less than the first temperature threshold, the charging control strategy of the battery is determined to be to continue charging and increase the charging current. When the battery temperature is greater than the second temperature threshold, the charging control strategy of the battery is determined to be to suspend charging. Wherein, the first temperature threshold is less than or equal to the second temperature threshold.

[0126] If the bad target parameter difference does not include a temperature difference, it is determined that the charging control strategy of the battery is to suspend charging.

[0127] Further, determining the charging control strategy of the battery based on the magnitude relationship between the temperature difference and the preset range includes:

[0128] When the temperature difference is less than a first preset temperature difference, the charging control strategy of the battery is determined to continue charging and increase the charging current, wherein the first preset temperature difference is a lower limit of a preset range corresponding to the temperature difference.

[0129] When the temperature difference is greater than a second preset temperature difference, the charging control strategy of the battery is determined to be charging suspension, wherein the second preset temperature difference is an upper limit value of a preset range corresponding to the temperature difference.

[0130] The battery charging control module 33 is used to control the charging process of the battery based on the charging control strategy.

[0131] Wherein, controlling the charging process of the battery based on the charging control strategy includes:

[0132] When it is determined that the charging control strategy of the battery is to suspend charging, a reminder is sent to the user in a first preset form, wherein the first preset form includes at least one of the following:

[0133] Sounds, words, lights, patterns and codes.

[0134] When it is determined that the charging control strategy of the battery includes maintaining continuous charging, a reminder is sent to the user in a second preset form, wherein the second preset form includes at least one of the following:

[0135] Sounds, words, lights, patterns and codes.

[0136] For example, a general adapter is provided with an LED light, which displays a red light during normal charging and a green light when fully charged. The present application reminds the user to continue charging by having a constantly lit red light and reminds the user to pause charging by having a flashing red light.

[0137] In addition, as an optional implementation scheme of an embodiment of the present application, when it is determined that the charging control strategy of the battery is to continue charging and increase the charging current, the increase amount or increase coefficient of the charging current is determined based on the difference between the first preset temperature difference and the temperature difference, wherein the greater the difference between the first preset temperature difference and the temperature difference, the greater the increase amount or increase coefficient, and the smaller the difference between the first preset temperature difference and the temperature difference, the smaller the increase amount or increase coefficient, wherein the increase coefficient is greater than 1. In addition, the increase in charging current mentioned in this application refers to increasing the charging current (i.e., increasing the charging power) while the charging voltage remains unchanged.

[0138] The battery charging control device provided in the embodiment of the present application determines the battery charging control strategy according to the target parameters after acquiring the target parameters in the environment, and controls the battery charging process based on the charging control strategy. Since the charging control strategy is determined according to the target parameters of the environment, when the battery is charged outdoors, even if the environment is not conducive to charging, the battery charging process can be controlled in real time to ensure that the battery will not be corroded and the charging time will be reduced, and during the charging period, the battery will not be overheated, so that the battery cells will not burn out, and the battery charging safety is ensured.

[0142] The processor is configured to execute the battery charging control method provided in the above embodiment.

[0143] The battery charging control system provided in the embodiment of the present application stores executable instructions of the processor in the memory. When the executable instructions are executed, the processor can determine the charging control strategy of the battery according to the target parameters after obtaining the target parameters in the environment, and control the charging process of the battery based on the charging control strategy. Since the charging control strategy is determined according to the target parameters of the environment, when the battery is charged outdoors, even if the environment is not conducive to charging, the charging process of the battery can be controlled in real time to ensure that the battery will not be corroded and the charging time will be reduced, and the charging time period will not be overheated, so as to ensure that the battery cells will not burn out and ensure the safety of battery charging.

[0144] Based on the same inventive concept, the present application provides an adapter, applying the battery charging control method provided in the above embodiment.
