Description

Technical Field

[0001] The present disclosure relates to the technical field of air-conditioning batteries, and in particular to a method, device, computer equipment and storage medium for monitoring charging of a portable air-conditioning multi-battery pack in chain topology. Background Art

[0002] With the development of technology, people use outdoor electrical equipment more frequently, and at the same time, the requirements for the capacity and performance of portable energy storage equipment have increased, such as the charging method of lithium-ion batteries for portable air conditioners. In order to balance the portability of equipment and the demand for battery capacity, major manufacturers have launched multi-battery pack daisy chain topology parallel structure products for portable air conditioners. Each battery pack can be used alone or in parallel, greatly increasing its capacity and the endurance of air conditioning equipment. At the same time, when the air conditioner battery is charging multiple battery packs, multiple battery packs can be charged in parallel without the need to control each battery pack individually.

[0003] However, current air conditioner battery multi-battery packs often use single battery packs to charge one by one, or although they are charged in parallel, each battery pack is often controlled by a main pack device to charge individually, and the next battery pack is charged after one battery pack is fully charged. The charging adapter cannot maintain the maximum power output for a long time, resulting in limited amount of power that can be charged in a certain time, and the maximum efficiency of charging cannot be achieved.

[0039] S300: Sending a charging packet switching failure signal to the chain topology charging system according to the constant voltage access adjustment value, so as to maximize the charging power of the chain topology charging system before all battery packs enter constant voltage charging.

[0040] In this embodiment, the constant voltage access adjustment amount is obtained based on the constant voltage charging access state parameter and the preset access state parameter. The constant voltage charging access state parameter is the charging data of the multiple battery packs of the portable air conditioner when chain topology charging is performed, that is, the constant voltage charging access state parameter is the current charging mode of each battery pack of the portable air conditioner, that is, the constant voltage charging access state parameter corresponds to the charging state of the battery pack of the portable air conditioner before constant voltage charging. Specifically, the constant voltage charging access state parameter is the battery self-charging state of each battery pack of the portable air conditioner when constant current charging is performed. By collecting the constant voltage charging access state parameter, it is convenient to determine the charging state of each battery of the portable air conditioner during the constant current charging process before entering the constant voltage charging. By processing the charging access adjustment of the constant voltage charging access state parameter and the preset access state parameter, it is convenient to determine the degree of change difference in the charging state of the battery pack of the portable air conditioner before constant voltage charging. After obtaining the constant voltage access adjustment value, whether the battery pack of the portable air conditioner enters constant voltage charging during the charging process can be determined, which facilitates the execution of chain topology constant current charging for each battery pack of the portable air conditioner, so that the charging power of the chain topology charging system will not be reduced, ensuring uninterrupted charging at the maximum charging power.

[0041] In this embodiment, after the constant voltage charging access state parameters are collected, the current charging mode of the portable air-conditioning battery pack is determined, and then the constant voltage charging access state parameters are compared with the standard charging access state parameters to facilitate determination of the difference between the current charging mode of the portable air-conditioning battery pack and the specified charging mode. Finally, based on the above difference value, the charging mode of the portable air-conditioning battery pack is adjusted to facilitate optimization of the charging power of the portable air-conditioning battery pack, so that the charging power is maintained at the maximum, thereby effectively improving the charging efficiency of multiple battery packs.

[0042] In one of the embodiments, the obtaining of the constant voltage charging access state parameters of the multiple battery pack modules of the portable air conditioner includes: obtaining the constant voltage access charging voltage of the battery pack of the portable air conditioner. In this embodiment, the constant voltage charging access state parameters are the charging data when chain topology charging is performed in the multiple battery packs of the portable air conditioner, that is, the constant voltage charging access state parameters are the current charging mode of each battery pack of the portable air conditioner, that is, the constant voltage charging access state parameters correspond to the charging state of the battery pack of the portable air conditioner before constant voltage charging. Specifically, the constant voltage charging access state parameters are the battery self-charging conditions of each battery pack of the portable air conditioner during constant current charging. By collecting the constant voltage charging access state parameters, it is convenient to determine the charging conditions of each battery of the portable air conditioner during the constant current charging process before entering the constant voltage charging. The constant-voltage charging access status parameter includes the constant-voltage access charging voltage of the battery pack of the portable air conditioner. The constant-voltage access charging voltage of the battery pack is the charging voltage of the battery pack of the portable air conditioner before entering the constant-voltage charging stage, that is, the constant-voltage access charging voltage of the battery pack is the real-time charging voltage of the battery pack of the portable air conditioner in the constant-current charging stage. By collecting the constant-voltage access charging voltage of the battery pack, it is convenient to determine the current charging state of the rechargeable battery pack of the portable air conditioner.

[0043] Further, the charging access adjustment processing of the constant voltage charging access state parameter and the preset access state parameter to obtain the constant voltage access adjustment includes: obtaining the adjustment of the constant voltage access charging voltage of the battery pack and the preset constant voltage access voltage to obtain the constant voltage access voltage adjustment. In this embodiment, the constant voltage charging access state parameter is the charging data when the multiple battery packs of the portable air conditioner are charged in a chain topology, that is, the constant voltage charging access state parameter is the current charging mode of each battery pack of the portable air conditioner, that is, the constant voltage charging access state parameter corresponds to the charging state of the battery pack of the portable air conditioner before constant voltage charging. Specifically, the constant voltage charging access state parameter is the battery self-charging state of each battery pack of the portable air conditioner when constant current charging is performed. By collecting the constant voltage charging access state parameter, it is convenient to determine the charging state of each battery of the portable air conditioner during the constant current charging process before entering the constant voltage charging. By performing the charging access adjustment processing of the constant voltage charging access state parameter and the preset access state parameter, it is convenient to determine the degree of change difference in the charging state of the battery pack of the portable air conditioner before constant voltage charging. The constant voltage charging access state parameter includes the constant voltage access charging voltage of the battery pack of the portable air conditioner. The constant voltage access charging voltage of the battery pack is the charging voltage of the battery pack of the portable air conditioner before entering the constant voltage charging stage, that is, the constant voltage access charging voltage of the battery pack is the real-time charging voltage of the battery pack of the portable air conditioner in the constant current charging stage. By collecting the constant voltage access charging voltage of the battery pack, it is convenient to determine the current charging state of the rechargeable battery pack of the portable air conditioner. By leveling the constant voltage access charging voltage of the battery pack with the preset constant voltage access voltage, the charging voltage of the battery pack before entering the constant voltage charging and the specified charging voltage are obtained by the least square difference, so as to reduce the error of the constant voltage access voltage leveling, so as to determine the degree of difference between the current charging state of the rechargeable battery pack of the portable air conditioner and the standard charging state, so as to determine whether the rechargeable battery pack of the portable air conditioner is to enter the constant voltage charging stage.

[0044] Furthermore, the method of sending a charging packet switching failure signal to the chain topology charging system according to the constant voltage access adjustment amount so as to maximize the charging power of the chain topology charging system before each battery pack enters constant voltage charging includes: detecting whether the constant voltage access voltage adjustment is greater than or equal to the preset access voltage adjustment; when the constant voltage access voltage adjustment is greater than or equal to the preset access voltage adjustment, sending a charging packet switching enable signal to the chain topology charging system to switch to constant current charging of the next battery pack. In this embodiment, the constant voltage access adjustment amount is obtained based on the constant voltage charging access state parameter and the preset access state parameter, and the constant voltage charging access state parameter is the charging data of the multiple battery packs of the portable air conditioner when chain topology charging is performed, that is, the constant voltage charging access state parameter is the current charging mode of each battery pack of the portable air conditioner, that is, the constant voltage charging access state parameter corresponds to the charging state of the battery pack of the portable air conditioner before constant voltage charging, and specifically, the constant voltage charging access state parameter is the battery self-charging state of each battery pack of the portable air conditioner when constant current charging is performed. By collecting the constant voltage charging access state parameters, it is convenient to determine the charging status of each battery of the portable air conditioner during the constant current charging process before entering the constant voltage charging. By processing the charging access adjustment of the constant voltage charging access state parameters and the preset access state parameters, it is convenient to determine the degree of difference in the charging state of the battery pack of the portable air conditioner before constant voltage charging. After obtaining the constant voltage access adjustment value, it is determined whether the battery pack of the portable air conditioner enters the constant voltage charging during the charging process, which facilitates the execution of chain topology constant current charging for each battery pack of the portable air conditioner, so that the charging power of the chain topology charging system will not be reduced, ensuring uninterrupted charging at the maximum charging power. The constant voltage access voltage difference is greater than or equal to the preset access voltage difference, indicating that the voltage of the battery pack currently being charged of the portable air conditioner has reached the voltage corresponding to the constant voltage charging mode, that is, it indicates that the battery pack currently being charged with constant current of the portable air conditioner will be charged with constant voltage. At this time, in order to ensure that the charging power of the chain topology charging system is not reduced, the charging packet cutting enable signal is output to switch to chain topology constant current charging of subsequent other battery packs, so that before the constant voltage charging of each battery pack of the portable air conditioner, the chain topology charging system maintains a high-power charging mode of constant current charging until all battery packs enter constant voltage charging.

[0045] In another embodiment, when the constant voltage access voltage difference is less than the preset access voltage difference, a charging pack cut-off disable signal is sent to the chain topology charging system to continue constant current charging of the current battery pack. At this time, the voltage of the battery pack currently being charged of the portable air conditioner is lower than the voltage corresponding to the constant voltage charging mode, and constant current charging needs to be continued to avoid the situation where the charging power of the chain topology charging system is reduced.

[0046] In one of the embodiments, the acquisition of the constant voltage charging access status parameters of the multiple battery pack modules of the portable air conditioner includes: acquiring the remaining power of the battery pack of the portable air conditioner when constant voltage charging is performed. In this embodiment, the constant voltage charging access status parameters are the charging data when chain topology charging is performed in the multiple battery packs of the portable air conditioner, that is, the constant voltage charging access status parameters are the current charging mode of each battery pack of the portable air conditioner, that is, the constant voltage charging access status parameters correspond to the charging status of the battery pack of the portable air conditioner before constant voltage charging. Specifically, the constant voltage charging access status parameters are the battery self-charging status of each battery pack of the portable air conditioner when constant current charging is performed. By collecting the constant voltage charging access status parameters, it is convenient to determine the charging status of each battery of the portable air conditioner during the constant current charging process before entering the constant voltage charging. The constant-voltage charging access status parameter includes the remaining constant-voltage charging power of the battery pack of the portable air conditioner. The remaining constant-voltage charging power of the battery pack is the remaining charging power of the battery pack of the portable air conditioner before entering the constant-voltage charging stage, that is, the remaining constant-voltage charging power of the battery pack is the real-time remaining charging power of the battery pack of the portable air conditioner in the constant-current charging stage. By collecting the remaining constant-voltage charging power of the battery pack, it is convenient to determine the current charging state of the rechargeable battery pack of the portable air conditioner.

[0047] Furthermore, the charging access adjustment processing of the constant voltage charging access state parameter and the preset access state parameter to obtain the constant voltage access adjustment includes: obtaining the difference between the constant voltage access charging remaining power of the battery pack and the preset constant voltage access remaining power to obtain the constant voltage access remaining power adjustment. In this embodiment, the constant voltage charging access state parameter is the charging data when the multiple battery packs of the portable air conditioner are charged in a chain topology, that is, the constant voltage charging access state parameter is the current charging mode of each battery pack of the portable air conditioner, that is, the constant voltage charging access state parameter corresponds to the charging state of the battery pack of the portable air conditioner before constant voltage charging. Specifically, the constant voltage charging access state parameter is the battery self-charging state of each battery pack of the portable air conditioner when constant current charging is performed. By collecting the constant voltage charging access state parameter, it is convenient to determine the charging state of each battery of the portable air conditioner during the constant current charging process before entering the constant voltage charging. By performing charging access adjustment processing on the constant voltage charging access state parameter and the preset access state parameter, it is convenient to determine the degree of change difference in the charging state of the battery pack of the portable air conditioner before constant voltage charging. The constant voltage charging access state parameter includes the remaining power of the battery pack of the portable air conditioner after constant voltage access charging. The remaining power of the battery pack after constant voltage access charging is the remaining power of the battery pack of the portable air conditioner before entering the constant voltage charging stage, that is, the remaining power of the battery pack after constant voltage access charging is the real-time remaining power of the battery pack of the portable air conditioner during the constant current charging stage. By collecting the remaining power of the battery pack after constant voltage access charging, it is convenient to determine the current charging state of the rechargeable battery pack of the portable air conditioner. By adjusting the remaining power of the battery pack after constant voltage charging with the preset remaining power after constant voltage charging, the least square difference between the remaining power of the battery pack before entering constant voltage charging and the specified charging voltage is obtained to reduce the error of the constant voltage charging remaining power adjustment, so as to facilitate determination of the degree of difference between the current charging state of the rechargeable battery pack of the portable air conditioner and the standard charging state, thereby facilitating determination of whether the rechargeable battery pack of the portable air conditioner is to enter the constant voltage charging stage.

[0048] Furthermore, the charging packet switching failure signal is sent to the chain topology charging system according to the constant voltage access adjustment amount, so that the charging power of the chain topology charging system is maximized before each battery pack enters the constant voltage charging, including: detecting whether the constant voltage access residual power adjustment is greater than or equal to the preset access residual power adjustment; when the constant voltage access residual power adjustment is less than the preset access residual power adjustment, sending a charging packet switching failure signal to the chain topology charging system to continue to perform constant current charging on the current battery pack. In this embodiment, the constant voltage access adjustment amount is obtained based on the constant voltage charging access state parameter and the preset access state parameter, and the constant voltage charging access state parameter is the charging data of the multiple battery packs of the portable air conditioner when the chain topology charging is performed, that is, the constant voltage charging access state parameter is the current charging mode of each battery pack of the portable air conditioner, that is, the constant voltage charging access state parameter corresponds to the charging state of the battery pack of the portable air conditioner before the constant voltage charging, and specifically, the constant voltage charging access state parameter is the battery self-charging state of each battery pack of the portable air conditioner when the constant current charging is performed. By collecting the constant voltage charging access state parameters, it is convenient to determine the charging status of each battery of the portable air conditioner during the constant current charging process before entering the constant voltage charging. By processing the charging access adjustment of the constant voltage charging access state parameters and the preset access state parameters, it is convenient to determine the degree of difference in the charging state of the battery pack of the portable air conditioner before constant voltage charging. After obtaining the constant voltage access adjustment value, it is determined whether the battery pack of the portable air conditioner enters the constant voltage charging during the charging process, which facilitates the execution of chain topology constant current charging for each battery pack of the portable air conditioner, so that the charging power of the chain topology charging system will not be reduced, ensuring uninterrupted charging at the maximum charging power. The constant voltage access residual power difference is less than the preset access residual power difference, indicating that the remaining power of the battery pack currently being charged of the portable air conditioner is lower than the remaining power corresponding to the constant voltage charging mode, that is, it indicates that the battery pack of the portable air conditioner needs to continue to be charged with constant current. At this time, the remaining power of the battery pack currently being charged of the portable air conditioner is lower than the remaining power corresponding to the constant voltage charging mode, and constant current charging needs to be continued to avoid the situation where the charging power of the chain topology charging system is reduced.

[0049] In another embodiment, when the constant voltage access residual power balance is greater than or equal to the preset access residual power balance, a charging packet switching enable signal is sent to the chain topology charging system to switch to constant current charging of the next battery pack. The constant voltage access residual power balance is greater than or equal to the preset access residual power balance, indicating that the residual power of the battery pack currently being charged of the portable air conditioner has reached the residual power corresponding to the constant voltage charging mode, that is, it indicates that the battery pack currently being charged with constant current of the portable air conditioner will be charged with constant voltage. At this time, in order to ensure that the charging power of the chain topology charging system is not reduced, the charging packet switching enable signal is output to switch to chain topology constant current charging of subsequent other battery packs, so that before the constant voltage charging of each battery pack of the portable air conditioner, the chain topology charging system maintains a high-power charging mode of constant current charging until all battery packs enter constant voltage charging.

[0050] In the actual chain topology charging process of the portable air conditioner multi-battery pack, the portable air conditioner is usually used outdoors, and the battery pack needs to be replaced frequently, especially in high power consumption mode. For example, when used outdoors in summer, the replacement frequency of the battery pack in the portable air conditioner increases significantly. When the multi-battery pack of the portable air conditioner is placed in the charging device of the chain topology charging system for charging, in order to maintain the use of the portable air conditioner under high power consumption, the battery pack that has just been placed in for charging is often taken out and installed on the portable air conditioner, which easily leads to a shorter effective working time of the portable air conditioner, resulting in frequent replacement of the battery pack, which not only affects the use of the portable air conditioner, but also easily causes unhealthy charging of the battery, resulting in a sharp decrease in the service life of the battery pack.

[0051] In order to avoid the situation where an incompletely charged battery pack is mistakenly taken, a charging packet switching failure signal is sent to the chain topology charging system according to the constant voltage access adjustment value, so that the charging power of the chain topology charging system is maximized before each battery pack enters constant voltage charging, and the following steps are also included:

[0052] Obtaining a constant current charging time of a battery pack of a multi-battery pack module of the portable air conditioner;

[0053] Detecting whether the constant current charging time of the battery pack is less than or equal to a preset constant current charging time;

[0054] When the constant current charging time of the battery pack is less than or equal to the preset constant current charging time, a chain end charging locking signal is sent to the chain topology charging system to lock the current battery pack in the charging position, and the charging sequence number of the battery pack is at the end of the chain topology charging sequence.

[0055] In this embodiment, the battery pack constant current charging time is the time duration for which the battery pack of the portable air conditioner is placed in the charging device of the chain topology charging system for constant current charging. By sampling the battery pack constant current charging time, it is convenient to determine the duration of constant current charging of each battery pack of the portable air conditioner during chain topology charging. The battery pack constant current charging time is less than or equal to the preset constant current charging time, indicating that the constant current charging time of the current battery pack of the portable air conditioner during chain topology charging is too short, that is, it indicates that the current battery pack of the portable air conditioner has been placed in the charging device for too short a time. For example, the preset constant current charging time is 70% to 85% of the constant current charging stage. At this time, the battery pack cannot be used as a battery pack that is taken out for replacement in the near future. A chain end charging locking signal is sent to the chain topology charging system to lock the current battery pack in the charging position, and the charging sequence number of the battery pack is at the end of the chain topology charging sequence. Specifically, for a battery pack that has been placed in the charging device for a short time, regardless of its charging position, its chain topology charging sequence number is set to the end, and the battery pack is in a charging lock state, ensuring that the battery pack will not be taken out again in a short time, thereby avoiding the use of a battery pack with insufficient power for battery replacement of a portable air conditioner.

[0056] Furthermore, the detecting whether the constant current charging time of the battery pack is less than or equal to a preset constant current charging time further includes:

[0057] When the constant current charging time of the battery pack is greater than the preset constant current charging time, obtaining the constant current and constant voltage switching times of the battery packs of the multi-battery pack module of the portable air conditioner;

[0058] Detecting whether the constant current and constant voltage switching times of the battery pack is greater than or equal to a preset switching times;

[0059] When the constant current and constant voltage switching times of the battery pack are greater than or equal to the preset switching times, a constant voltage unlocking signal is sent to the chain topology charging system to unlock the charging of the current battery pack and enter the constant voltage charging stage.

[0060] In this embodiment, the constant current charging time of the battery pack is greater than the preset constant current charging time, indicating that the constant current charging time of the current battery pack of the portable air conditioner is sufficient when charging in the chain topology, which can ensure that the remaining power of each battery pack is maintained at a high power level, avoiding frequent replacement. For battery packs with a long service life, due to the large number of constant current and constant voltage charging cycles they have experienced, the loss of such battery packs is more serious than that of new battery packs. In order to extend the service life of the battery pack, by obtaining the number of constant current and constant voltage switching of the battery pack, it is convenient to determine the complete charging cycle of each battery pack, thereby facilitating the determination of the service life of each battery pack. The number of constant current and constant voltage switching of the battery pack is greater than or equal to the preset switching number, indicating that the battery pack performs a large number of complete constant current charging and constant voltage charging times, that is, it indicates that the replacement frequency of the battery pack is high, and the internal polarization of such battery packs is serious. By sending a constant voltage unlocking signal to the chain topology charging system, the battery pack can be unlocked for replacement only after it has fully entered the constant voltage charging stage, avoiding being taken out for replacement before entering the constant voltage charging stage.

[0061] In another embodiment, when the constant current and constant voltage switching times of the battery pack are less than the preset switching times, a constant current terminal unlock is sent to the chain topology charging system. At this time, the replacement frequency of the battery pack is low, that is, the battery pack is a new battery pack, and the battery pack can be used for replacement before entering the constant voltage charging.

[0062] The above-mentioned various preset variables are all set in the database for timely retrieval, and different preset variables are placed in different storage units, that is, in different storage stacks. Moreover, the constant current charging time of the battery pack and the number of constant current and constant voltage switching times of the battery pack can be collected through corresponding detectors, for example, through the charging timer and counter in the charging collection module.

[0063] In one of the embodiments, the present disclosure also relates to a portable air conditioner multi-battery pack chain topology charging monitoring device, comprising: a charging acquisition module, a constant voltage access processing module and a charging packet cutting module; the charging acquisition module is used to obtain the constant voltage charging access status parameters of the multi-battery pack module of the portable air conditioner; the constant voltage access processing module is used to perform charging access adjustment processing on the constant voltage charging access status parameters and preset access status parameters to obtain a constant voltage access adjustment amount; the charging packet cutting module is used to send a charging packet cutting failure signal to the chain topology charging system according to the constant voltage access adjustment amount, so as to maximize the charging power of the chain topology charging system before each battery pack enters the constant voltage charging.

[0064] In this embodiment, after the charging acquisition module collects the constant voltage charging access state parameters, the current charging mode of the portable air-conditioning battery pack is determined, and then the constant voltage access processing module compares the constant voltage charging access state parameters with the standard charging access state parameters to facilitate determining the difference between the current charging mode of the portable air-conditioning battery pack and the specified charging mode. Finally, the charging packet cutting module adjusts the charging mode of the portable air-conditioning battery pack according to the above difference value, so as to optimize the charging power of the portable air-conditioning battery pack, so that the charging power is kept at the maximum, and the charging efficiency of multiple battery packs is effectively improved.
